As the heart of the cold water compressor, it is good or bad to determine whether the whole unit can run properly. The main function of the compressor oil is lubrication, cooling, the screw compressor lubricant also plays a role in capacity regulation. Thus, for the problem of lubricating oil can not be underestimated, so today to share with you is: cold water pump should pay attention to oil and oil.
     First, the oil filling note
     1, we must give the cold water machine oil must be through the quality certification, and different brands of oil can not be mixed use. Different kinds of refrigerants should correspond to different kinds of lubricating oil. Ensure the cleanliness of the system before feeding the water cooler, no impurities such as welding slag.
     2, the use of synthetic oil in the cold water unit, and to ensure that the oil is not exposed to the atmosphere for a long time. The first boot should be thoroughly vacuum pumping system.
     3, in order to ensure the normal operation of the unit, the system should be dehumidification, it is recommended to use dry nitrogen into the system for drying, and then vacuum treatment.
     4, when the customer lubrication oil filling system should ensure that the total amount of lubricating oil to achieve the required charge. If the customer's cold water system has been filled with enough oil, but in order to maintain the need to release some of the oil, then re filling the lubricating oil, as long as the amount of oil can be added to the.
     Two, some suggestions on the replacement of lubricating oil
     1, oil change cycle: if the cold water compressor has been running for 10000 hours, should check the lubricating oil. If the compressor is running for the first time, it is recommended to replace the oil after 2000 hours of operation and clean the oil filter. Check the system is clean, if the chiller system operating conditions are good, every 20000 hours or every 4 years to replace the lubricating oil.
     2, avoid solid residue and metal impurities through the oil filter, which may lead to bearing damage, it is recommended to install a pressure switch (optional). When the pressure difference between the two sides of the oil filter reaches the set value, the differential pressure switch acts, so that the system stops, and the bearing can be prevented from serious damage due to oil loss.
