RWB-II-222E screw compressor for cooling methanol in refrigeration system is a refrigeration equipment widely used in chemical, pharmaceutical, food and other industries. However, due to various reasons, the compressor may fail and need to be repaired. This article will introduce the common faults and maintenance methods of RWB-II-222E screw compressor.
Common faults of screw compressors:
1.Compressor failure to start: This can be due to a power failure, a control system failure, or a mechanical failure.
2.Abnormal compressor operation: such as abnormal sound, excessive vibration, too high or too low temperature, etc., may be caused by mechanical failure, control system failure or lubrication system failure.
3.Poor refrigeration: It can be caused by refrigerant leakage, clogged condenser or evaporator, control system failure, etc.
Screw compressor maintenance method.
1.Power failure: Check whether the power supply line is normal and replace the damaged power supply parts.
2.Control system failure: Check whether the control system circuit is normal, replace the damaged circuit board or sensor.
3.Mechanical failure: Disassemble the compressor for inspection and replace damaged bearings, seals or rotors and other components.
4.Lubrication system failure: Check whether the lubrication system is normal, replace damaged oil pump or oil filter and other components.
5.Refrigerant leaks: Find leaks and fix them, and replenish the right amount of refrigerant.
6.Condenser or evaporator blockage: Disassemble the condenser or evaporator for inspection, remove the blockage and clean it.
Precautions for screw compressors.
1.Before performing repairs, the power supply must be cut off and the pressure inside the compressor must be relieved.
2.When disassembling the compressor, use the correct tools and methods to avoid damaging other components.
3.In the maintenance process, pay attention to protect your own safety and avoid accidents.
4.If you encounter a problem that cannot be solved, it is recommended to seek the help of a professional maintenance personnel.
RWB-II-222E screw compressor for methanol cooling in refrigeration system is an important refrigeration equipment, and its maintenance work requires professional skills and experience. When encountering a fault, it is necessary to carefully analyze the cause and take the correct repair method. At the same time, it is necessary to pay attention to safety and protection of the equipment to ensure its normal operation and service life.
