20 Ton Chiller – Chiller Manufacturer
20 ton chiller is a very important refrigeration equipment for an enterprise. Its operation stability has a non-negligible effect on production efficiency and product quality. Therefore, regular maintenance of the chiller is required to ensure the normal operation of the chiller. of.
So, how to maintain the 20 ton chiller?
1. Replace lubricating oil
After the 20 ton chiller group 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 it is necessary to observe and check the oil quality regularly, and replace it in time if any problem is found.
In addition, I would like to remind everyone that the grade of lubricating oil to be replaced must comply with the technical data to avoid additional damage to the chiller due to incorrect use of lubricating oil.
2. Replace the dry filter
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, the filter element inside the drying filter must be replaced regularly to keep the inside of the system dry for a long time.
3. Calibration of the safety valve
Both the condenser and evaporator of the 20 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 the pressure. Prevent possible damage to the human body caused by high voltage. Therefore, in order to ensure the safety of the staff, the safety valve must be checked regularly.
4. Cleaning of condenser and evaporator
The cooling water of the water-cooled condenser is an open circulation loop, and tap water is generally used to circulate through the cooling tower. However, 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.
