There are many types of industrial chillers. When purchasing a chiller, different chiller suppliers make different chiller solutions. Therefore, customers need to face choices in the process of purchasing chillers. How can they choose a suitable chiller Suppliers?  Are there any problems that we need to pay attention to when purchasing chillers? The following Oumal chiller manufacturer will take you to analyze together.

First of all, when purchasing a chiller, it is necessary to know whether it is an air-cooled chiller or a water-cooled chiller, whether the chiller model recommended by the supplier meets your requirements, whether the cooling capacity is sufficient, and whether the power supply voltage matches , If different chiller suppliers have different prices, we compare air-cooled chillers with water-cooled chillers, it will be difficult to choose a suitable supplier. Because the price of water-cooled chillers is cheaper than that of air-cooled chillers. The same water-cooled chiller also distinguishes the difference between the box-type chiller ( Packaged water cooled chiller)  and the open-type chiller.

When comparing the price of the chiller of the same scheme, we can't see the low price and choose the low-priced supplier. We must compare the configuration of the chiller. First of all, the compressor is the core component of the chiller, and the brands of compressors are different. , The price is naturally different. We can’t just look at the compressor brand as a well-known brand to determine that the quality of this chiller is high, and other accessories should be balanced, including pump brand, pump material, pump pressure, evaporator type and evaporator material, condenser, fan , And the control panel. Take the screw chiller for example, the control panel has a button type, LCD Touch Screen, PLC Controller, and different control systems, resulting in different costs for the screw chiller.

Secondly, the after-sales service of the chiller is also worthy of our attention. Whether the manufacturer of the chiller is professional, whether there are professional service personnel, and the time of the after-sales service are all factors that we need to consider when purchasing the chiller. The production time of the chiller, payment method, price terms, each difference will lead to the different price of the chiller. Only by choosing a supplier that suits our positioning can we get quality service at a preferential price.

Oumal chiller has favorable price, high-end configuration and professional technical team. It is a trusted chiller supplier in China. If you want to purchase a chiller, please contact us, Oumal will make the best chiller solution for you with best price .

As we all know, the application of industrial chillers is very wide, of which chillers are the most widely used in the plastics industry. So, why does the plastics industry need to use water chillers, and where do they need to use water chillers in the plastics industry?

We know that a chiller is a kind of refrigeration equipment that cools water and recycles it. In plastic production, the high temperature easily affects the molding of plastic products. The chiller can be used to cool down injection molds and improve the quality of plastic products. So which plastic machinery needs to use a chiller? Below, Omar Refrigeration will take you to understand the application of chillers in the plastics industry.

Injection molding machine: In the injection molding process of plastic products (televisions, computers, washing machines, mobile phones, refrigerators, air conditioners, plastic toys, automotive plastic parts, etc.), whether the product can be cooled (cooling down) in a timely and effective manner will directly affect the appearance of the product And shape qualification rate, which affects production efficiency, production costs and corporate profits.

Air cooled chiller is easy to install, and widely used in the injection molding machines. If you want to use one chiller to provide chilled water for several injection molding machines, the water-cooled screw chiller for central water chiller is a good choice.

Plastic Extruder machine (Sheet Extruder Machine ): Extruder extrudes pipes, trunking, cables and various plastic profiles. The heated and melted raw materials are cooled by a freezing water bath after being molded by the mold, and the water temperature in the freezing water bath must be kept constant. Due to the high production speed, large cooling capacity units are required for the surface. If the existing frozen pool is large enough, the unit may not be equipped with a water tank.

Bottle blowing machine: mainly produces all kinds of mineral water bottles and soda bottles. Compressed air drying-clean, dry compressed air is required for blowing, and the water in the compressed air can be removed by using the frozen water provided by the industrial chiller as a cold source. Also chiller used in other machines like Compression molding machine, stretch film machines, cast film machine, cup making machine, plastic forming machine, cup making machines, cup lid machines, cup forming machines, sheet machine and so on.

Oumal Chiller specializes in the production of chillers for the plastics industry, including air-cooled chillers, water-cooled chillers, screw chillers, etc. The appropriate chiller model is selected according to the size of the customer's machine.

Ultrasonic cleaners also called Ultrasonic cleaning machines, are widely used in surface spray treatment industry, machinery industry, electronics industry, medical industry, semiconductor industry, watch jewelry industry, optical industry, textile printing and dyeing industry. Other industries, etc. Compared with other cleaning, ultrasonic cleaning machine has the advantages of high cleaning rate, less residue, short cleaning time, and good cleaning effect. Ultrasound has a cleaning effect on all parts to be cleaned that can be immersed in liquid. It is not limited by the surface shape of the cleaning parts, such as deep holes, slits, and grooves. Can be cleaned.

In our country, the military electronics complete machine factory has begun to promote, and has received the double benefits of not only improving product reliability, but also reducing the cost of after-sales service. In the production of connectors, connectors, adapters and other devices, they must also be cleaned before electroplating and assembly, otherwise the dust and oil adsorbed on these assembled parts will inevitably affect their conductivity and insulation performance, especially some complex multi-core This is especially true for connectors.

Why do ultrasonic cleaning machine need to be equipped with industrial chillers?

The ultrasonic cleaning machine is equipped with a chiller mainly to reduce the temperature of the tank body when the ultrasonic cleaning machine is working, and effectively prevent the cleaning agent from volatilizing.

As long as it is a gas-phase ultrasonic cleaner or an ultrasonic cleaner that uses a solvent-based cleaning medium, it must be equipped with a chiller.

Solvent-based cleaning media are relatively volatile, and the cleaning fluid is easy to volatilize at high temperatures. If a chiller or cooling device is not equipped, the solvent volatilizes faster.

The special smell of solvents will also be emitted. Many solvent-based cleaning media are toxins, which is not conducive to the health of equipment operators.

How to choose a chiller for an ultrasonic cleaning machine?

The following factors need to be considered when the ultrasonic cleaning machine is equipped with a chiller:

1. The power of the heating tube

2. The power of the ultrasonic

3. The organic matter, toxic, needs to be used for volatilization

4. The cleaning fluid is more expensive and needs to be used for volatilization.

Such as: enclosed optical ultrasonic cleaning machine, 17-slot automatic resin optical lens cleaning machine, optical glass ultrasonic cleaning machine, these three kinds of ultrasonic cleaning machines need to use chillers.

Selection formula: (heating tube power + ultrasonic power) x safety factor, the safety factor is generally 1.2.

Ultrasonic cleaners special chillers generally require clean water quality. Therefore, when we are equipped with chillers, we need to use 304 stainless steel or 316 stainless steel for the water pump, water tank, pipes and pipe fittings of the chiller.

During the use of the chiller, sometimes freezing occurs, and the chilled water malfunctions and alarms. The evaporator is one of the four core components of the chiller, and its importance is self-evident. Once it fails, the chiller will also go on strike. Today we will talk about the more common evaporator failures, namely Icing, to analyze the cause and find a solution. Why does the chiller freeze? How to eliminate the icing failure of the evaporator?

1. Look at the type of chiller, whether it is a low-temperature Chiller machine or a room temperature chiller machine.

For low-temperature chillers, use antifreeze instead of water. Such as Glycol.

A normal temperature chiller uses water for circulation. The temperature of this chiller is generally set at 5 degrees. The factory has set it before leaving the factory. Of course, you can set it yourself. If the temperature is too low, it will freeze. If the temperature of the medium and high temperature chiller is lower than 5 degrees without adding antifreeze, it is easy to cause the evaporator to freeze and cause the chilled water failure alarm.

2. See if the chiller is installed with a temperature sensor

The temperature probe will work in coordination with the control board. When the temperature is too low, the temperature probe will tell the main board that the main board will sound an alarm and stop automatically, so there will be no icing.

3. Insufficient refrigerant

During the use of the chiller, refrigerant leakage or blockage will occur. After the refrigerant is reduced, the evaporation pressure will be too low, causing the evaporator to freeze. The location of the icing is sometimes in the evaporator. If the refrigerant leaks, The method of elimination is to deal with the leaking part first, add enough refrigerant, and the fault will be eliminated. If the expansion valve is blocked, replace the expansion valve with a new one.

OUMAL CHILLER Supply all kinds of chillers, such as low temperature chiller, industrial chiller, Brine chiller, screw chiller, glycol chiller……If you are looking for a cooling water system, contact us. Will provide you the best chiller solution with good price.

Both air-cooled screw chillers and air-cooled scroll chillers are air-cooled chillers. Air-cooled chillers use air cooling, eliminating the need for cooling towers, cooling water pumps and piping systems that are essential for cooling water systems. Areas with poor water quality cause condenser fouling and water pipe blockage, and also save water resources. It is the most economical and simple model for maintenance and repair of cold water air-conditioning equipment.

 

Advantage:

Functionally: The air-cooled screw chiller and the scroll chiller have the same refrigeration function. Refrigeration, heating, heating, and energy are all electric energy.

Application industry: Du Shi is mainly used in industries such as industry, medicine, food, coal, and shopping malls.

 

Comparison of unit characteristics:

The air-cooled screw chiller is named air-cooled screw chiller because of its key component-the compressor adopts a screw type. The state of the unit from the evaporator is a gas refrigerant; after adiabatic compression by the compressor, it becomes a high temperature and high pressure state. The compressed gas refrigerant is cooled and condensed at equal pressure in the condenser, and then changes into a liquid refrigerant after condensation, and then expands to a low pressure through a throttle valve and becomes a gas-liquid mixture. Among them, the liquid refrigerant under low temperature and low pressure absorbs the heat of the substance to be cooled in the evaporator and becomes a gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline to start a new cycle. These are the four processes of the refrigeration cycle. It is also the main working principle of the screw chiller.

 

The air-cooled screw chiller adopts the international brand screw compressor, and is equipped with high-quality and high-efficiency copper pipes to make the condenser, evaporator and world-famous control components, so that the unit has small size, low noise, large energy, long life, and easy operation And other advantages, its beautiful and exquisite shape design and reliable and stable high-performance quality are outstanding among similar products!

2. Advanced intelligent defrosting method, microcomputer control analyzes the temperature of each point at any time, optimizes the defrost cycle time, and ensures that the defrosting in time does not affect the normal operation of the equipment.

3. Professional motor cooling device. Meet the harsh operating conditions.

4. Using a new generation of high-efficiency heat exchange tubes, the heat transfer coefficient can be increased by 5%. The double groove tube sheet design and advanced tube expansion technology make the structure more sealed and reliable, and completely avoid the possibility of mutual penetration.

5. Generally, no water pump is installed in the unit, and there is no water tank, so an external water tank is needed for circulation.

 

The air-cooled scroll chiller is called an air-cooled scroll chiller because its compressor uses a fully enclosed scroll compressor, and the condenser uses a finned fan. The scroll air-cooled chiller has a cooling capacity from 27.8kW to 284.5kW and a heating capacity from 29kW to 303.5kW, which can meet the different load requirements of various occasions. The unit has a compact structure, small floor space, simple pipeline design, only requires an external water pipe, and is easy to install and maintain. The machine components are integrated and modular. The modular unit is assembled from 2 to 8 modules and has the characteristics of large cooling capacity, mutual standby, and gap operation.

Chiller installation and maintenance instructions

1. Installation instructions

1. Machine installation, it is required to lay flat and not tilt;

2. There should be a maintenance space of about one meter on both sides of the machine;

3. Connect the cooling water inlet and outlet specifications of this machine to your cooling system;

4. The ice water pipe must be replaced with a loop to allow the ice water to circulate;

5. The ice water pipeline must be insulated;

6. When connecting the power supply, please make sure that the power supply is sufficient to bear the maximum load of the chiller’

7. The power supply of the unit must be controlled separately;

8. Must be grounded to ensure safety.

2. Troubleshooting

When the unit fails, observe the abnormal indication, then turn off the main power switch, and check according to the following steps;

1. When it shows abnormal cooling, it should be checked;

a. Whether the ice water source is sufficient;

b. Whether the water pipe valve is open;

c. Whether the ice water pump is operating normally;

d. Whether the water pipeline is disconnected.

After confirming that it is correct, press the reset button to reset, and then turn it on after 5 minutes’

2. When the refrigerant is insufficient, check the unit pipeline for leakage and blockage, reset it after troubleshooting, and restart it after 5 minutes;

3. When the display is too low, check whether the ice water pipe valve is open and whether the ice water circulates normally, and restart it after 5 minutes;

4. When the oil pressure is too low, you should look through the window to see if the oil is sufficient, and add it if it is insufficient;

5. When the compressor is overloaded, it should be checked;

a. Electromagnetic switch, whether there is aging, open circuit, poor contact, etc.;

b. Check whether the insulation resistance of the compressor is normal with a resistance meter;

c. Use a universal meter to check whether the coil resistance of the compressor is balanced. If there is any abnormality, the compressor must be replaced (note: in this case, the compressor cannot be turned on blindly without finding the cause of the failure);

When the pump is overloaded, the inspection method is the same as 5.

Three, maintenance

1. For example, in the injection molding industry: to reduce the production of "pouring sweat" from the mold, before stopping the plastic machine, turn off the cold water valve of the attached mold, or turn off the cold water, which will increase the water temperature in the mold cavity. Prevent the mold from rusting.

2. The chiller has been used for more than six months, and the high/low pressure often fails, or the cooling capacity is reduced. Please arrange for staff to clean the radiator, (if the chiller is equipped with a pressure gauge, pay attention to whether the pressure is higher than 21KG/cm2, such as If it exceeds, clean the radiator, or check whether the water pipe has been turned off). If you follow the above instructions for repairs several times, the chiller fault alarm will sound for a long time, please notify the factory to contact for repair.

3. The chiller will not be used for a period of time. Due to the solidification of water and dirt, the water pump rotor must be rotated before starting to avoid the pump blades not rotating, which may cause protection of the pump.

Water chiller cleaning method (it is necessary to find professionals to operate)

1. Clean the condenser: first remove the dust on the condenser, and then clean it with a special washing liquid. The washing liquid should be used carefully and the concentration of the washing liquid should be adjusted. Do not touch, touch the skin and eyes, if you accidentally touch it, please Rinse immediately with plenty of water and send to the hospital for treatment if necessary.

2. Cleaning the evaporator: first remove the dirt on the evaporator, clean it with clean water, do not damage the evaporator, and drain the sewage.

Four, matters needing attention

The company’s product warranty period is 15 months, and the warranty will not be provided for the following situations:

1. Those who disassemble the crew by themselves

2. Self-adjusting the pressure controller, temperature controller and control panel data, and self-adding refrigerating oil and refrigerant to cause damage to the unit;

3. The equipment and accessories of the unit are damaged by the customer's own transportation or improper installation;

4. The thermal load of the user exceeds the load of the unit, causing damage to the unit.

Warning: When not in use in winter, please drain all the water to avoid damage to the machine due to icing. Remember!

Common failures in chiller maintenance

During the maintenance of the chiller, in some environments with many dust layers, after the chiller has been used for a period of time, we will find that the chiller is noisy, and there are many dust layers on the accessories. This is a common phenomenon in the use of the chiller. At this time, the chiller is We need to serve it.

First of all, the chiller is a device that provides cold to the outside world, in other words it takes away the heat, so the ventilation environment required by the chiller is very important. The water cycle of the chiller is a simple process, but we must pay attention to the details of the simple process. If the front hood of the chiller is filled with dust, it will affect the heat dissipation of our chiller. Once the heat dissipation is affected The impact will directly cause the cooling effect of the chiller to drop sharply. If we do not remove the ash layer from time to time, on the one hand, it will affect the cooling effect, on the other hand, it will cause the internal components to burn out. After many chillers have been used for a period of time, the poor cooling effect is basically caused by this aspect.

Secondly, the temperature of about 20 degrees Celsius is just suitable for the strong growth of our microorganisms. When we use the chiller, sometimes its temperature is controlled at about 20 degrees Celsius. A large number of microorganisms accompany our water cycle, and some microorganisms are attached to our filter. Above the board, the waterway is not smooth, causing the chiller to produce a lot of noise. Even some microorganisms are attached to the heat exchanger of the chiller, causing the chiller's cooling effect to be poor.

 

Combining the above two points, I must maintain the chiller regularly and clean up the dust and debris in the chiller in time, so that the functions of our chiller can be guaranteed in all aspects, and it can maintain normal operation. The following are common faults in the maintenance of chillers.

 

1. Power failure. If a power failure occurs during the use of the chiller, it may cause the fuse to blow, the phase sequence protector to burn, phase loss, or instability. The solution is simple, that is, to replace the corresponding protector, Or fuse to ensure no phase loss and power supply stability.

 

2. Water pump failure. If there is a water pump failure, it may be caused by the overload protection action on the AC contactor of the water pump, the capacitor burned out, or the water pump itself; it is necessary to deal with the overload problem, replace the capacitor, or the water pump identity problem.

 

3. Water pump failure. If the compressor fails, it may be because the compressor capacitor is burned out and the compressor coil winding is abnormal. At this time, replace the capacitor or unwind the winding to restore it to normal.

 

4. Pressure switch failure, if it is a high and low pressure switch failure, it may be that the filter is blocked, the system is insufficient in winter, the circulating cooling water is stopped, the heat exchange cooling fan stops working, etc., it is necessary to replace the appropriate filter and add refrigerant to the cooling system ; At the same time, check whether the sweat cooling water circulating pump is normal; check whether the fan is working normally, if it is abnormal, repair it as soon as possible.

 

1. Reverse alarm:

1. The three-phase wiring of the power supply is wrong (pay attention to the auxiliary control line), check the wiring problem, turn on the power switch and the water pump switch to burn the fuse, and the circuit is short-circuited. Check the control wire and the main power line. The water pump rotor is stuck. Loosen the motor rotor;

 

2. If the fuse is not installed, install an appropriate fuse.

 

3. The power indicator is damaged, replace the electronic board.

 

2. Compressor failure

 

1. Compressor coil is short and open circuit, replace the matched compressor

 

2. Compressor overload protector automatically trips, adjust the current limit of the protector appropriately within the allowable range and press the reset button

 

Three, water pump failure

 

1. The water pump motor coil is short, open circuit, repair the motor coil or replace the motor

 

3. The overload protector of the water pump automatically trips, and the current limit of the protector is appropriately increased within the allowable range. Press the reset button halfway.

 

Fourth, the compressor is frosting

 

1. If the circulating water is flowing or the valve is not opened, check the water valve and all pipelines to ensure unobstructed flow, and install short-circuit pipelines.

 

2. The circulating water pipe configuration is too small, increase the diameter of the circulating water pipe to ensure the normal water circulation.

 

Troubleshooting of chiller maintenance

1. The temperature sensing wire and temperature measuring body are dirty, wipe the temperature measuring body clean

2. The temperature control meter is damaged, repair or replace the temperature control meter

3. Poor contact of the temperature sensing wire, repair or replace the temperature sensing wire

4. There is no circulating water in the water tank, and a circulating water path is short-circuited between the chilled water outlet and the inlet

5. The temperature control meter is out of control. Replace the temperature control meter. High pressure failure. Poor heat dissipation, dirty radiator, bad air to clean the radiator, improve ventilation conditions, and the cooling fan does not work. Check whether the fan motor is burned out or short circuit. Repair or replace the motor. Damaged, replace the high pressure

In many industries, industrial chillers are required. The industrial chiller mainly achieves the refrigeration effect through absorption cycle vapor compression or vapor compression. These liquids can flow through the heat exchanger to cool the air or equipment. When we use industrial chillers, in order to ensure safety, we should master the following precautions for safe operation of industrial chillers.

1. Check whether the chiller is damaged before installation.

2. In order to facilitate future use and maintenance, the place where the industrial chiller is installed must be a flat ground.

3. The chiller should be placed in a ventilated, constant temperature machine room. In winter, if the temperature is too low, it needs to be filled with antifreeze.

4. Choose the water pipe with the appropriate pipe diameter, the cooling system and the cold water system when the chiller is running at the maximum power, and connect them correctly.

5. For ordinary applications, the water flow speed through the evaporator and condenser is about 1-8m/s.

6. Under any load conditions, the water flow should remain stable.

7. After the leak test is completed, all the nozzles of the chiller must be treated with rust prevention.

 

How to ensure the safe operation of industrial chillers: The safety of the operating environment determines the service life of the specific industrial chillers. In order to maintain the stability of the industrial chillers, in the actual installation process, the power supply of the industrial chillers must first be ensured. It is recommended Consult the chiller supplier during the installation of the industrial chiller. The chiller requires the installation of an independent power supply for the industrial chiller, and safely and effectively controls the voltage and current to meet the normal operation of the industrial chiller. At the same time, the power supply is separated to avoid various overloads and affect the normal operation of the industrial chiller. It can also be achieved when running for a long time. N state, there will be no security problems.

 

Maintain a clean and hygienic operating environment: The installation environment of industrial chillers can achieve the purpose of extending the service life of industrial chillers. If the industrial chillers are in a relatively harsh environment, they will have a great impact on the life of key parts, especially for large amounts of water cooling. Industrial chillers have high requirements for the environment, but not high requirements for the environment. He uses a clean environment to reduce the dirt under the industrial chiller, which plays a vital role.

 

Freon cooling requires careful maintenance: Many industrial cooling water equipment is made of Freon to achieve the purpose of lowering the ambient temperature. Therefore, in actual use, users can improve the cooling effect by entering high-quality refrigerants. Domestic refrigeration plants must meet the overall needs of the market. , With the popular high quality of feet. The refrigerant is used to reduce the temperature of the medium and achieve the purpose of improving the efficiency of the entire industrial chiller, which plays a vital role in meeting many special low-temperature environments. Industrial chillers have higher requirements for the operating environment. In daily use, mastering the common sense of industrial chillers can achieve the purpose of improving the operating efficiency of industrial chillers. At the same time, by extending the service life of industrial chillers, the daily maintenance funds required by enterprises can be reduced.
