The chiller is already an indispensable part of the plastics, electronics, chemical, food preservation, ink printing, pharmaceutical, machinery and other industries. Its main function is to provide chilled water to the equipment / products to achieve the purpose of cooling.
▲ SUNNY-HVAC air cooled box chiller
The cooling effect of an industrial chiller depends on its quality. However, we all know that industrial chillers will always wear out during use. Therefore, we need to record and analyze its operating parameters regularly, listen to the sounds emitted during operation, check the use of snow and frozen oil, and regularly. Perform maintenance operations for it.
The daily maintenance of industrial chillers is very simple. I suggest you consider the following points:
01
Check the compressor regularly
The compressor is the "heart" of the industrial chiller, and its quality directly affects the stability of the chiller when it is used.
If the compressor is repaired after failure, the cost is relatively high, especially the precision of the screw compressor is high and expensive. Therefore, if you hear abnormal sounds or other conditions in the compressor, be sure to contact the chiller factory to find a professional engineer to check, find out the cause and carry out maintenance.
02
Clean the condenser and evaporator regularly
The condenser/evaporator is the second most important component of an industrial chiller, preferably once every six months.
The cooling water of the water-cooled condenser is an open circulation loop. The tap water used is recycled through the cooling tower, which easily decomposes and deposits impurities to form scale on the water pipe, affecting the heat transfer effect; the excessively thick scale also makes the cooling water The flow cross section is reduced, the amount of water is reduced, and the condensing pressure is increased.
Therefore, when the tap water used is poor in water quality, it is preferable to wash it at least once a year to remove the scale in the pipe, and it is preferable to carry out a water treatment operation on the tap water.
03
Regular inspection of safety valves
The condenser and evaporator of the industrial chiller are all pressure vessels. According to the regulations, the safety valve should be installed on the high pressure end of the chiller, that is, the condenser body. Once the unit is in an abnormal working environment, the safety valve can automatically relieve pressure. To prevent high pressure damage to the human body.
04
Regularly change lubricants
After long-term use of the industrial chiller, 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 inspect the oil quality regularly. Once the problem is found, it should be replaced in time. The brand of the replacement lubricant is best provided by the original manufacturer.
05
Regularly change the dry filter
The drying filter is an important part to ensure the normal circulation of the refrigerant. Since water and refrigerant are incompatible with each other, if the system contains moisture, it will greatly affect the operating efficiency of the chiller. Therefore, it is very important to keep the internal drying of the system. The filter element inside the drying filter must be replaced regularly.
