Function Description

Each product is engineered to fulfill the specific functional requirements of its matched equipment, ensuring efficient, safe, and stable operation. The core functions of key product categories are as follows, explained in simple, practical terms:

Drilling Rig & Transmission Parts

Cardan shafts (ZJ51L SWC315BH-1410) and roller shafts (ZJ-30C) transmit power to drilling components, ensuring smooth operation of ZJ series drilling rigs. Connecting beams (JJ746609-120400) and intermediate shaft bearing housings (TDS QT450-10 P/N 9702020206) provide structural support, maintaining component alignment and stability. Slurry pump shafts (CAM073M) and with pump shaft assemblies (ZJ-45 3042) drive pump impellers, ensuring stable fluid circulation for drilling operations. Quick connectors (ZJ-40LDB PSZ75A H3) enable fast and leak-free connection of hydraulic hoses, reducing installation time.

Brake & Safety Parts

PS series hydraulic control disc brake devices (PSZ75A-2-00) and disc brake blocks (PSE75A-ⅲ) provide reliable braking force for drilling rigs, preventing accidents during drilling and lifting operations. ZJ-70D electromagnetic eddy current brakes control rig speed, ensuring precise operation. Emergency relay valves (ZJ-30C SH382-3527/4900300030) ensure emergency braking in critical situations, enhancing operational safety. Friction discs (W24-07-301) enable smooth clutch engagement and disengagement, protecting transmission components.

Boiler & Valve Parts

WNS1.0-1.25-YQ boiler plunger valves (U11S-16C DN15) and high-pressure globe valves (PKH10) regulate fluid flow in boiler systems, ensuring safe and efficient boiler operation. Three-position four-way rotary valves (34ZS-21.25) control hydraulic fluid direction, enabling smooth switching of equipment working states. Cylinder covers (P/N 36001-0503) seal engine cylinders, preventing gas leakage and maintaining engine performance.

Pneumatic & Hydraulic Parts

High-pressure hoses (1/2″×150MPa×25m) and hydraulic connectors (QBJ5013006) transmit high-pressure hydraulic fluid, ensuring reliable operation of ZJ series hydraulic systems. Accumulator charging valves (DQ70BS Y0N0201 M16×1.5/M14×1.5) maintain accumulator pressure, ensuring stable hydraulic system performance. Balance solenoid valves (Y/F0025) regulate fluid pressure, enabling precise control of hydraulic components. O-type sealing strips (P1700402AA) and spring seals (ZJ45 180×220×15) provide reliable sealing, preventing fluid leakage in high-pressure environments.

Filters & Electrical Parts

3512B air filters (8N-6309) and filter elements (3827643, 9N3367) remove impurities from air and fluid, protecting engines and hydraulic systems from wear. Filter regulators (512605540020150000) filter and regulate compressed air, ensuring clean air supply for pneumatic systems. Dynamos (24V 80A) provide electrical power for drilling rig systems, while toggle switches (VA863 380/12) control electrical circuits. Torque gauges (ZJ50L 63C19) and weight gauges (JZZ1-420KN, JZ series) measure torque and weight, providing accurate data for drilling operations.

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, ZJ30C roller shafts, ZJ45 with pump shaft assemblies (3042), TDS intermediate shaft bearing housings (9702020206), and DQ70BS accumulator charging valves (Y0N0201) 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 cardan shafts and roller shafts, wear-resistant rubber for O-type sealing strips and oil seals, and corrosion-resistant materials for boiler valves. 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 (3827643, 9N3367) and air filters (8N-6309) adopt a snap-on design for quick replacement; quick connectors (ZJ-40LDB PSZ75A H3) enable fast installation. Even complex parts like PS series brake devices have clear installation marks, reducing installation time.

• Safety-Critical Design: Parts related to equipment safety—such as emergency relay valves, PS series brake devices, and high-pressure globe 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 seals (5300200111, P1700402AA), hoses, and electrical connectors daily. Ensure there is no looseness, leakage, or damage. For O-type sealing strips, spring seals, and oil seals, check for aging or cracks—replace them immediately if issues are found to avoid fluid leakage and equipment damage. Inspect brake blocks (PSE75A-ⅲ) for wear and adjust or replace as needed.

Regular Cleaning & Replacement

Replace air filters (8N-6309), filter elements (3827643, 9N3367), and stem packings (C22176-08) every 25-30 days (or according to equipment operation hours) to maintain performance. Clean friction discs (W24-07-301) and brake devices to remove debris, preventing wear and ensuring braking performance. Clean hydraulic connectors and quick connectors to avoid blockages.

Lubrication Maintenance

Apply API-certified lubricating oil to moving parts such as cardan shafts (ZJ51L SWC315BH-1410), roller shafts (ZJ-30C), and thrust bearings (6839819) regularly. Follow the equipment manual for lubricant type and quantity to reduce friction loss and extend part service life. Check springs (5710-115, P9000140AA) for elasticity and replace if worn.

Storage & Handling

Store unused parts in a dry, ventilated, and clean warehouse, away from moisture, dust, and corrosive substances. Precision parts like torque gauges (ZJ50L 63C19) and filter elements should be kept in sealed packaging to avoid damage. When handling heavy parts (e.g., intermediate shaft bearing housings), use appropriate tools to prevent collision and deformation.

Replacement Standards

Replace parts immediately if they show the following signs: excessive wear (e.g., friction discs W24-07-301), deformation (e.g., cardan shafts), leakage (e.g., oil seals 5300200111), or failure to meet operational requirements (e.g., torque gauges with inaccurate readings).
