Hunan Ruisheng Electromechanical Xiaobian will explain the maintenance steps of air compressor intake valve in detail, and the maintenance of Chigo screw air compressor intake valve usually requires replacing piston spring, piston O-shaped diagram, sealing ring and check valve spring.
1. Shut down and release all internal pressure before disassembly. Note: Do not disassemble screws, screw plugs and other parts while Chigo screw air compressor is running or under pressure;
2. Disassemble all pipes connected to the intake valve;
3. Disassemble the 4 bolts and elastic pads connected to the intake valve body and the Chigo screw air compressor, and remove the intake valve from the Chigo screw air compressor; Disassembly of the retaining ring and O-ring from the intake valve body;
4. Remove the check valve assembly and spring from the valve body;
5. Remove the piston spring and piston assembly;
6. Clean the valve body, ensure that the internal passage is clean, and remove the old sealing ring on the intake valve flange;
7. Replace the old parts with new parts provided by spare parts and install them to the intake valve. Note: To ensure the seal, grease the parts;
8. Put an O-ring on the piston, grease the outside with some oil and install the valve body;
9. Install new piston springs;
10. The piston is built into a new check valve spring, and then the check valve assembly is installed;
11. Place a new PTFE O-ring on the valve body and lock the nut, at this time you need to take out the bolt and gently tap on the head. When disassembling, pay attention to the order of each part;
12. Clean the air intake surface of Chigo screw air compressor before installing the new flange gasket;
13. Tighten 4 bolts and lock the expansion washer.
Air compressor maintenance precautions:
1. Do not disassemble screws, screw plugs and other components in Chigo screw air compressor running or under pressure;
2. Use the same type of Chigo screw air compressor oil to apply flange sealing ring to strengthen the sealing effect;
3. Regularly check the intake valve (generally 600 hours or two months), the venting valve and the loading solenoid valve to ensure that its seal does not leak and the operation is normal.
