Regular inspection of the 9 parts of the chiller can save you money and your colleagues will not tell you!

In your factory or laboratory, the chiller is responsible for cooling and controlling the temperature of the manufacturing equipment. They are like a caring "care worker" to cool and control the production equipment. Then you should love it and treat it like you treat your family members before you can extend their lifespan, quality and quantity to promote production.

Regular inspection of the following 9 parts can make the chiller more efficient, healthier and less expensive!

1. Maintenance of the compressor

Take the screw compressor as an example, the screw is a precision component, which determines the performance of the chiller. If you often work in bad conditions, it may fail, and the maintenance cost is very expensive. A small part may have to be at least thousands of pieces, not to mention the labor cost. And if it can be repaired regularly to avoid the failure, it will save money. It is generally tested by a professionally qualified engineer, with a cycle of two years.

2. Regular inspection of safety valves

The condenser is a large part of the chiller. On the screw chiller, the safety valve is installed on it. In order to avoid the impact of the condenser high pressure on the unit, the safety valve can serve the purpose of automatic pressure relief. So it should be checked regularly, whether it is malfunctioning and aging, and it must be replaced if it fails.

3. Regularly clean the scaled parts

For example, cooling water towers: larger chillers usually cool the condenser temperature through the cooling water tower, and the water tower will circulate for a long time, which will also cause contamination of impurities and scale in the condenser tubes, causing damage to the unit. Therefore, regular cleaning of the condenser helps to clean the interior.

For example, the condenser, evaporator, and heat dissipation pipes, especially the connected parts, have a long running time of the chiller, which is easy to produce scale, which will affect the refrigeration efficiency and heat dissipation of the unit. Therefore, the pipes should be cleaned according to the specific operating environment. It is usually cleaned every six months.

4. Change the lubricant regularly

The water chiller is also a mechanical device. It also uses lubricating oil during operation. After a long working time, the natural oil quality will deteriorate and impurities such as air and moisture will penetrate. Therefore, regular replacement is a good thing for the water chiller. . Replace at least once a year.

5. Periodic drying filter replacement

The drying filter is a component that filters moisture in the refrigeration system, fills the unit with dry refrigerant, avoids moisture, and damages the refrigeration system. Therefore, the dryer filter is always working during the operation of the unit, and it should be checked at least once a year, and it should be checked once every six months under harsh operating conditions.

6. Check the refrigerant quantity of the chiller

If it is not enough, the refrigerant needs to be replenished in time to avoid the insufficient cooling effect, which will cause "burn" to the unit.

The following are some inspections and maintenance of electrical components and regulating components.

7. Check whether the main line of the electric control system is externally insulated

If it is a humid environment, it should be tested frequently to ensure that the circuit is normal and there is no leakage.

8. Check the high and low pressure switch of the unit

The high and low pressure switch of the unit is a device to ensure the safety of the compressor. If it exceeds or falls below the rated pressure, it will automatically cut off the line and the compressor will stop working. If this set of values is not within the normal range, it will affect the use of the compressor.

9. Check the thermostat of the unit to ensure the normal display of the thermostat

The thermostat is a device for the staff to directly control the temperature. It can be displayed normally to ensure the normal operation of the chiller. Therefore, you should regularly check whether it is displayed or abnormal.

After the inspection of the above 9 parts, the test machine should be run and the total correction should be carried out to test whether the superheat is normal and whether there are abnormal conditions such as abnormal noise and smell. Regular inspection is the maintenance of each chiller equipment, which can extend the use of equipment for 3-6 years.

Kedley summarized with you that the 9 parts of the chiller to be regularly checked, the compressor, the scale-prone pipeline, the safety valve, the dryer, the lubricating oil, the refrigerant, the line insulation, the pressure switch, and the temperature switch. In fact, it is easy to understand that the four major parts of refrigeration plus oil, electricity, water (dryer dehydration), refrigerant and two switches that control pressure and temperature.

Regularly check the 9 parts of the chiller. Don't wait until the equipment is broken before you pay for repairs! Bai Hua wasted money.
