8. On-Site Fault Maintenance Cases

The following are 4 real on-site fault maintenance cases of pneumatic and hydraulic components, which are common faults in actual use. Through these cases, users can quickly judge and solve similar faults, reduce equipment downtime, and provide reference for technical maintenance:

Case 1: Two-Position Three-Way Button Valve 23r1-l8 Air Leakage Fault

• Fault Phenomenon: During the operation of the drilling platform, the 23r1-l8 button valve has obvious air leakage after being pressed, and the system pressure drops rapidly, which affects the normal operation of the pneumatic control system.

• Fault Judgment: After on-site inspection, it is found that the internal sealing ring of the button valve is aging and deformed (the sealing ring has been used for more than 1200 working hours), resulting in poor sealing and air leakage; at the same time, there is dust in the valve core, which affects the closing of the valve core.

• Maintenance Method: Stop the machine immediately, cut off the air source; disassemble the button valve, remove the aging sealing ring and valve core; clean the valve core and valve inner cavity with professional cleaning agent; replace it with the original genuine sealing ring, reinstall the valve core and button valve; connect the air source, press the button to test, the air leakage fault is solved, and the valve operates flexibly.

• Preventive Measures: Regularly clean the button valve and check the sealing ring status during daily maintenance; replace the sealing ring in time when it is found to be aging; keep the air source clean to avoid dust entering the valve.

Case 2: Check Valve 50.8mm qf539 Backflow Fault

• Fault Phenomenon: The hydraulic system of the loader is unable to maintain pressure, and the hydraulic oil flows back, resulting in the loader bucket unable to stay in the specified position, affecting the loading operation.

• Fault Judgment: On-site inspection shows that the check valve qf539 is clogged by impurities in the hydraulic oil, and the valve core cannot be closed tightly, resulting in backflow of hydraulic oil; the valve core surface is worn, and the fit gap with the valve body is too large, which also aggravates the backflow fault.

• Maintenance Method: Stop the machine, drain the hydraulic oil in the system; disassemble the check valve qf539, remove the valve core, clean the valve inner cavity and valve core with cleaning agent; grind the worn valve core surface to restore the fit gap; reinstall the check valve, replace the hydraulic oil and oil filter; start the machine for test run, the system pressure is stable, and there is no backflow fault.

• Preventive Measures: Replace the hydraulic oil and oil filter regularly according to the maintenance cycle; install a high-precision oil filter in the hydraulic system to improve the oil cleanliness; check the check valve regularly for clogging and wear.

Case 3: Brake Cylinder 115*125 Movement Inaccuracy Fault

• Fault Phenomenon: The brake cylinder 115*125 of the crane moves inaccurately during braking, and there is obvious jitter, resulting in unstable braking and potential safety hazards.

• Fault Judgment: After on-site inspection, it is found that the piston rod of the brake cylinder is worn, and there is excessive friction between the piston and the cylinder barrel; the air source pressure is unstable, and the filter decompression unit is clogged, resulting in uneven air supply to the cylinder.

• Maintenance Method: Disassemble the brake cylinder, remove the piston rod, grind the worn surface of the piston rod; replace the piston sealing ring; clean the filter element of the filter decompression unit, adjust the air source pressure to the rated range; reinstall the brake cylinder, test the braking performance repeatedly, and the cylinder moves smoothly and accurately, and the braking is stable.

• Preventive Measures: Regularly check the wear of the piston rod and piston; apply lubricating oil to the piston rod regularly; clean the filter decompression unit regularly to ensure stable air source pressure.

Case 4: Valve Island 10p-18-8a-mp-r-y-4cncch + PR Control Failure

• Fault Phenomenon: The valve island of the industrial automation production line fails to receive control signals, and the corresponding valves cannot be opened or closed normally, resulting in the production line being shut down.

• Fault Judgment: On-site inspection shows that the connection between the valve island and the control system is loose, resulting in poor signal transmission; at the same time, the internal solenoid valve of the valve island is faulty, and the electromagnetic coil is burned out due to overheating.

• Maintenance Method: Cut off the power supply of the valve island; check the connection line between the valve island and the control system, re-tighten the loose connection; replace the faulty solenoid valve with the original one (provided by us); connect the power supply, test the control signal, the valve island operates normally, and the production line resumes operation.

• Preventive Measures: Regularly check the connection status of the valve island and the control system; check the electromagnetic coil of the solenoid valve for overheating; ensure the stability of the power supply to avoid voltage fluctuation damaging the solenoid valve.
