Maintenance & Care Suggestions (Field Engineer Practical Tips)

Routine Inspection Items

Check mud pump bumper cups, shaft seals, and O-rings every 8 working hours for wear, swelling, and fluid leakage; inspect hydraulic valve action, IBOP actuator status, and fastener tightness every 50 working hours; monitor mud pump casing temperature, top drive sealing flange pressure, and hydraulic system pressure every 100 working hours; clean impurities on sealing surfaces and filter elements regularly to avoid blockage.

Scheduled Replacement Cycle

Vulnerable rubber seals, bumper cups, and shaft packing: replace every 800 working hours or immediately after leakage; hydraulic valves, IBOP actuators, and mud pump valve guides: full inspection every 2400 working hours, replace when wear clearance exceeds 0.03mm; transmission shafts, sprockets, and high-strength fasteners: performance test every 3000 working hours, replace when wear or deformation is detected.

Installation Avoidance Tips

Before installing sealing components, clean the mating surface thoroughly to remove mud, iron filings, and impurities to prevent cutting the seal; when installing hydraulic valves and mud pump components, ensure correct installation direction and interface sealing, and do not use brute force to avoid damaging precision parts; tighten fasteners with a standard torque wrench, and the torque error shall not exceed ±5% to prevent over-tightening fracture or under-tightening loosening; rubber parts should be stored in a cool and dark environment before installation to avoid premature aging.

Storage & Transportation Notes

Rubber and sealing parts should be stored in a dry, ventilated, light-proof environment to avoid UV irradiation and high-temperature aging; precision hydraulic components and mud pump alloy parts should be coated with anti-rust oil for long-term storage and protected by shock-absorbing packaging; during transportation, avoid collision and extrusion to prevent deformation of precision components.
