On-Site Fault Maintenance Cases

The following are 3 real on-site fault cases of the 106.60.270.00 Air Piping Installation for Lanzhou LS Drawworks JC50D, including fault phenomena, cause analysis, and solutions, which can provide practical reference for on-site maintenance personnel.

Case 1: Air Leakage at Pipeline Joints, Resulting in Reduced Air Pressure

Fault Phenomenon: During the operation of the Lanzhou LS Drawworks JC50D, the air pressure of the air piping system is unstable and lower than the rated value, and there is a hissing sound at the joint of the F9-2-93 Pipe and GB3289.28-82 Connector, affecting the normal operation of the drawworks.

Cause Analysis: After on-site inspection, it is found that the 106.02.270.04 Washer at the joint is aged and deformed, losing the sealing effect, resulting in air leakage; at the same time, the GB6170-86 Nut at the joint is loose due to long-term equipment vibration, which aggravates the air leakage.

Solution: Shut down the drawworks, release the air pressure in the pipeline, disassemble the joint, take out the aged washer, replace it with a new 106.02.270.04 Washer that is consistent with the original model, then re-install the connector, and use a torque wrench to tighten the GB6170-86 Nut to the specified torque. After the replacement, conduct a pressure test, and confirm that there is no air leakage and the air pressure is stable before restarting the equipment. The fault is completely eliminated, and the system operates normally.

Case 2: Air Filter Blockage, Resulting in Insufficient Air Supply

Fault Phenomenon: The drawworks’ air-powered control components respond slowly, and even fail to act occasionally. After checking the air source, it is found that the air supply is normal, but the air output of the air piping system is significantly reduced, and the Air Filter has obvious dust accumulation on the surface.

Cause Analysis: The construction site has more dust, and the Air Filter has not been cleaned for a long time, resulting in severe blockage of the filter element. The compressed air cannot pass through smoothly, leading to insufficient air supply to the air-powered components, and thus affecting their normal operation.

Solution: Shut down the equipment, disassemble the Air Filter, take out the filter element, clean the filter element with compressed air (blow from the inside out to avoid dust entering the clean side), and if the filter element is severely damaged or the cleaning effect is not good, replace it with a new Air Filter of the same specification. After installation, restart the equipment, check the air output, and confirm that the air-powered components respond normally. The fault is solved, and the system operates stably.

Case 3: Pressure Relay Valve Malfunction, Resulting in Excessive Air Pressure

Fault Phenomenon: During the operation of the drawworks, the air pressure of the air piping system suddenly rises above the rated value, and the pressure gauge shows an overpressure state. If it is not handled in time, it may damage the pipeline and valves. After inspection, it is found that the QY411 Pressure Relay Valve does not act when the pressure exceeds the rated value.

Cause Analysis: The QY411 Pressure Relay Valve has been in operation for a long time, and the valve core is stuck by impurities in the compressed air (the Air Filter was not replaced in time before, resulting in unfiltered impurities entering the valve body), and the pressure regulation spring is fatigued and deformed, resulting in the valve failing to work normally and unable to release pressure automatically when overpressure occurs.

Solution: Shut down the equipment, cut off the air source, release the air pressure in the pipeline, disassemble the QY411 Pressure Relay Valve, clean the valve core and valve body with clean diesel oil to remove impurities, check the pressure regulation spring, and replace it with a new spring of the same specification if it is fatigued and deformed. After reassembly, adjust the pressure to the rated range, conduct a pressure test, and confirm that the valve can automatically release pressure when overpressure occurs. At the same time, replace the Air Filter element to prevent impurities from entering the system again. The fault is eliminated, and the pressure of the air piping system is stable.
