Solution to damage of screw chiller compressor
1. Remove the drying filter, and use the temporary detachable connecting pipe or copper pipe joint to connect the short-circuit part;
2. Inject the cleaning agent into the pipeline system to clean the circulating flow. If necessary, replace the cleaning agent for multiple cleaning;
3. Blow the whole system dry with nitrogen until there is no residual detergent;
4. Install a good compressor and dry filter, and use pressure nitrogen to detect leakage. If there is no leakage, the remaining nitrogen can be discharged into the atmosphere through the high-pressure end angle valve;
5. At the same time, vacuum the high and low voltage terminals, and then check all power supplies and electric control systems;
6. Add liquid refrigerant and start the machine for test after the refrigerant reaches 80%~90%. Note: the compressor must be heated for 2 hours.
7. Replace the compressor refrigerant oil and observe the oil consumption during the operation of the compressor.
