Compressor shutdown for screw compressor repair

Compressor shutdown for screw compressor repair Among the many refrigeration compressors, the screw compressor is the most extensive one. When the screw compressor suddenly stops after working for a day, a reasonable treatment method should be carried out to ensure that it can be used normally next time. The countermeasures for compressor shutdown in screw compressor maintenance: 1. The screw compressor has the characteristics of small size, light weight, and easy maintenance. It is a faster-developing model of refrigeration compressors. The shutdown causes the equipment to fail to work properly and reduces the equipment's utilization efficiency. 2.Switch the main unit to "manual" mode, reduce the energy and internal pressure ratio to about 20%, and adjust the suction valve appropriately. 3. Check the exhaust pressure, suction pressure and condenser liquid level, and recover the freon in the evaporator to the fluorine cooler. 4. After the fluorine collection is completed, reduce the energy to internal pressure ratio to the "0" position, press the stop button, wait for the oil level to decrease, and then stop the main oil pump, thin oil pump, glycol pump, circulating water pump, and cut off the "power supply" "Make good parking records. 5. Regardless of whether the problem is large or small, the maintenance time will greatly affect the work schedule and efficiency. Regular inspections must be done when using the equipment daily. It is not only a method of coping with screw compressors, but also to start up and shut down. This is to keep the equipment in use for a long time without causing problems. If it is handled well, it can also improve work efficiency. And to extend the service life.
