Maintenance & Care Recommendations
Proper maintenance of engineering parts is essential to extend their service life and ensure equipment performance. Below are practical, easy-to-follow maintenance suggestions tailored to our products:
• Regular Inspection: Check drilling rig components (TL45110 Volute Liner, ZJ70D Pressure Regulator), engine parts (3512 Air Motor 7C-3372), brake components (ZJ70DB Guide Belt), and electrical sensors (SK-8Y21A) every 500 operating hours for signs of wear, cracks, leakage, or damage. Replace damaged parts promptly to avoid equipment failure, especially safety-critical components.
• Filtration & Seal Maintenance: Replace pilot filters (4I3948), oil filters, and seals (O-Ring AG3750011102, Piston Seal XWSY471) every 1000 operating hours or as recommended by the equipment manual. Clean filter housings regularly to prevent impurity buildup, and check seals for leakage to maintain hydraulic/pneumatic system integrity.
• Lubrication: Apply appropriate lubricating oil to moving parts such as clutch springs (LT600*250T), connecting rods (5I7637), and turntable connectors. Use lubricants that meet OEM specifications to reduce friction and wear, and avoid mixing different types of lubricants. Pay special attention to lubricating one-way clutches and winch components.
• Storage: Store spare parts in a dry, clean, and well-ventilated area. Avoid direct sunlight, high temperature, and humidity to prevent rust and aging. For electrical components (WS9020 Resistor, SK-2Z16 Thyristor) and precision sensors, store them in anti-static, sealed packaging to protect their performance and accuracy.
• Professional Installation & Testing: Ensure parts are installed by trained maintenance technicians with experience in industrial equipment. Follow OEM installation guidelines to avoid incorrect installation, which can cause part damage or equipment malfunction. After installation, test the equipment to ensure the part is working properly—especially for precision components like pressure regulators and sensors.
