Structural Features

Our products are designed with a focus on compatibility, durability, and ease of use—directly addressing the common challenges users face with generic parts, such as poor fit, short service life, and difficult installation. Key structural features include:

• 1:1 OEM Compatibility: Every part is manufactured to the exact specifications of the original equipment. For example, ZJ50LDB RVP-20 check valves, ZJ70 M16×200 bolts, ZJ70D PSZ75A/13II high-pressure hoses, and BF1262 fuel filters match the original equipment perfectly, allowing direct replacement without modifying the equipment structure or using special tools.

• High-Durability Materials: Key parts use industry-grade materials to withstand harsh conditions—high-strength steel for bolts, bearings, and pump components, wear-resistant rubber for O-rings and oil seals, and corrosion-resistant materials for filters and electrical connectors. This ensures resistance to wear, corrosion, high temperature, and high pressure, extending part service life.

• User-Friendly Design: We prioritize on-site operation convenience. For example, filter elements (1R0749) and air filters (P777869) adopt a snap-on design for quick replacement; high-pressure joints (BX152) enable fast and secure connection. Even complex parts like hydraulic control valves (ZJ50 BK-F-W2) have intuitive installation marks, reducing installation time.

• Safety-Critical Design: Parts related to equipment safety—such as shut-off valves (DN25 140MPa), check valves, and boiler solenoid valves—adopt multiple safety structures to prevent failure during high-load or emergency operations, protecting operators and equipment.

Maintenance & Care Recommendations

Proper maintenance and care can significantly extend the service life of parts, reduce equipment downtime, and lower maintenance costs. Below are practical, easy-to-follow recommendations for on-site teams:

Daily Inspection

Check the condition of O-rings (530301010950053007), high-pressure hoses (ZJ70D PSZ75A/13II), electrical connectors, and brake pads (BK-1-6A) daily. Ensure there is no looseness, leakage, or damage. For oil seals (53X8630R-2), gaskets, and sealing rings, check for aging or cracks—replace them immediately if issues are found to avoid fluid leakage and equipment damage. Inspect pressure gauges and oil temperature gauges for accurate readings.

Regular Cleaning & Replacement

Replace air filters (P777869), BF1262 fuel filters, 1R0749 filter elements, and ZJ70 oil return filter elements every 25-30 days (or according to equipment operation hours) to maintain performance. Clean impellers (641212105, F10147) and horizontal sand pumps (SB6*8J-13 75kW) to remove debris, preventing blockages and ensuring pump efficiency. Clean HEPA filters (29538489/29538491) to maintain air cleanliness.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as 222244CA/W33/C3 roller bearings, DAM005M bearing assemblies, and crossheads (5259573) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check arimite lubrication pumps (331380-N1) and hand oil pumps (CAT3412/4W0788) for proper operation and refuel as needed.

Storage & Handling

Store unused parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive substances. Precision parts like ZKX-3450BM-G05L encoders, SK-8L03A sensors, and filter elements should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., pump head bodies, bearing boxes), use appropriate tools to prevent collision and deformation.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., brake pads BK-1-6A, bearings), deformation (e.g., pulleys ZJ45 Ф1270), leakage (e.g., BX152 gasket rings), or failure to meet operational requirements (e.g., check valves, solenoid valves).
