250 Ton Chiller – Chilling System Manufacturer

The main content of maintenance of 250 ton chiller includes daily maintenance and regular inspection. Regular inspection and maintenance can ensure the long-term normal operation of the unit and prolong the service life of the unit.

1. The 250 ton chiller compressor is a very critical part of the unit, and the quality of the compressor is directly related to the stability of the unit. The user should have an operation record, record the operation of the unit, and establish a maintenance technical file. The complete technical information is helpful to discover hidden troubles and take measures early to prevent the occurrence of troubles.

2. Since the cooling water of the condenser is an open circulation loop, the tap water generally used is recycled through the cooling tower. When the content of calcium salt and magnesium salt in the water is large, it is easy to decompose and deposit on the cooling water pipe to form scale, which affects heat transfer. Excessive scaling will also reduce the circulation section of cooling water, reduce the amount of water, and increase the condensation pressure. Therefore, when the water quality of the cooling water used is poor, the cooling water pipe should be cleaned at least once a year to remove scale and other dirt in the pipe.

3. After the 250 ton chiller is used for a long time, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture inside the oil will increase, so the oil quality should be observed and checked regularly. Once a problem is found, it should be replaced in time.

4. The dry filter is an important part to ensure the normal circulation of the refrigerant. Since water and refrigerant are incompatible with each other, if there is water in the system, it will greatly affect the operating efficiency of the unit. Therefore, it is very important to keep the inside of the system dry, and the filter element inside the drying filter should be replaced regularly.

5. Both the condenser and evaporator of the 250 ton chiller are pressure vessels. According to regulations, a safety valve should be installed on the high-pressure end of the unit, that is, the condenser body. Once the unit is in an abnormal working environment, the safety valve can automatically release Pressure, in order to prevent possible damage to the human body caused by high pressure. Therefore, the regular calibration of the safety valve is very important for the safety of the whole unit.

6. If there is no other special reason, the general unit will not produce a large amount of leakage. If a certain amount of refrigerant leaks due to improper use or after maintenance. Refrigerant needs to be added again. Charge the refrigerant and pay attention to the type of refrigerant used by the unit.
