Xu Rui shares common faults and maintenance of chillers

Maintenance and maintenance of chiller: the use of chiller can reduce the preheating time of the mold, improve the surface quality of the finished product and enable fully automated production

Industrial chiller (chiller) ice water machine maintenance: keep the surface of the industrial chiller (chiller) ice water machine clean, clean the ice water and cooling filter regularly, the industrial chiller (chiller) ice water machine has been used for more than six months, or the high and low pressure engines often fail, or the cooling capacity is reduced, please check whether the high pressure gauge pressure is higher than 300PSI

If it exceeds, the staff should be arranged to clean the condensation, keep it clean, and improve the effect of the radiator

1 . Screw compressor Screw compressor is a very critical component in the unit, the quality of the compressor is directly related to the stability of the unit

If the compressor fails. Due to the high installation accuracy requirements of screw compressors, it is generally necessary to ask the factory for maintenance

2 . Cleaning of the condenser and evaporator The cooling water of the water-cooled condenser is an open circulation loop, and the tap water generally used is circulated 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 the heat transfer

If the scale is too thick, the flow section of the cooling water will be reduced, the water volume will be reduced, and the condensing pressure will rise

Therefore, when the quality of the cooling water used is poor, the cooling water pipes should be cleaned at least once a year to remove scale and other dirt in the pipes
