Maintenance & Care Recommendations

Proper maintenance of drilling rig and industrial parts is crucial to extending their service life and ensuring equipment reliability. Below are practical, easy-to-follow maintenance recommendations for core products:

General Maintenance Principles

• Inspect parts regularly: Weekly inspection for high-load components (gears, bearings), monthly inspection for hydraulic seals and filters, and quarterly inspection for electrical components. Replace worn or damaged parts immediately to prevent further equipment damage.

• Keep parts clean: Remove dust, mud, and oil stains from mechanical parts and electrical components to avoid performance degradation. For hydraulic parts, ensure hydraulic oil is clean (replace oil every 500 working hours).

• Store parts properly: Store parts in a dry, ventilated environment (temperature 0-30℃, humidity ≤70%) to prevent rust and corrosion. Rubber parts (O-rings, seals) should be stored away from direct sunlight to avoid aging.

Product-Specific Maintenance

• ZJ70DB Disc Brake O-Ring OK019000701: Inspect the O-ring every month for cracks, deformation, or oil leakage. Replace the O-ring if it shows signs of wear, and apply a thin layer of hydraulic oil before installation to prevent damage.

• 3512 Pump 313-7770: Clean the pump filter every 200 working hours, and replace the pump if there is abnormal noise or reduced flow rate. Use only OEM-specified fuel to avoid pump wear.

• LHE3200AZ Inclinometer Inner Cylinder: Clean the cylinder surface before installation, and check the seal for damage. Avoid dropping or impacting the cylinder to prevent internal sensor damage. Calibrate the inclinometer every 6 months to ensure measurement accuracy.

• Oil Suction Filter Element ZJ50L TFX-400×100: Replace the filter element every 300 working hours or when the pressure difference exceeds 0.1MPa. Clean the filter housing before installing a new element.

• Electrical Components (SK-2Z16 Transformer T15, SKZYP Control Board): Check electrical connections regularly for looseness. Keep electrical components dry to avoid short circuits. Replace parts if they show signs of overheating (discoloration, burning smell).

Maintenance Safety Tips

When performing maintenance, shut down the equipment and cut off power/hydraulic pressure to avoid accidental operation. Use proper tools (e.g., torque wrenches for bolt tightening) to prevent component damage. Follow safety guidelines for oilfield operations, including wearing protective equipment (gloves, goggles) when handling oil and chemicals.
