The screw compressor cannot run at full load due to various faults, including pressure switch, solenoid valve, intake valve, and control pipeline issues. Solutions involve checking and replacing faulty components.
Case Details
Answer:
(1) Fault phenomenon. After the air compressor is started, the intake valve servo cylinder cannot be fully opened.
(2) Cause analysis.
- 1) Pressure switch failure;
- 2) Three-way solenoid valve failure;
- 3) Intake valve malfunction;
- 4) Discharge solenoid valve failure;
- 5) Pressure maintenance valve malfunction;
- 6) Control pipeline leakage.
(3) Elimination method.
- 1) Check and replace the pressure switch;
- 2) Check and replace the three-way solenoid valve;
- 3) Check and handle after disassembly;
- 4) Check and replace the discharge solenoid valve;
- 5) Check whether the valve seat and check valve plate are worn after disassembly;
- 6) Check the leakage location and handle it.
