Function Description

Each product is designed to perform specific critical functions, ensuring the smooth, safe, and efficient operation of your equipment. Here’s how our key parts work:

• ZJ70D Spring Safety Valve SCA28X-16T: Installed on ZJ70D drilling rigs, this valve automatically releases excess pressure (set to 1.2MPa) to protect hydraulic systems and pipelines from overpressure damage, ensuring safe operation.

• JC70B Drawworks Seal Washer 7001050425: Creates a tight seal between drawworks components, preventing oil leakage and maintaining system pressure, which is essential for the stable operation of JC70B drawworks.

• ZJ45 Roller Square Filling Φ89: Supports and stabilizes the roller system of ZJ45 drilling rigs, reducing friction and ensuring smooth rotation during drilling operations.

• Clutch Friction Plates (LT500×250T, 700×135mm): Transmit power in drilling rig clutches, enabling smooth engagement and disengagement, which is critical for controlling winch and drawworks operations.

• Filters & Sensors (TF-250×80F-Y, SK-8Y34A): The inlet filter removes impurities from hydraulic oil to protect system components, while the pressure sensor monitors system pressure in real time, providing data for safe operation.

• Quick High Pressure Connector 1″×35MPa: Connects high-pressure pipelines in drilling rigs and hydraulic systems, ensuring leak-proof performance under high pressure (35MPa) and facilitating quick assembly and disassembly.

Structural Features

Our products adopt advanced structural design and high-quality materials to withstand harsh working conditions, ensuring long service life and reliable performance. Key structural features include:

• ZJ70D Spring Safety Valve SCA28X-16T: Made of high-strength carbon steel, with a precision spring and sealing structure for accurate pressure control; 3/4″ thread design ensures easy installation and tight connection, suitable for high-pressure hydraulic systems.

• JC70B Drawworks Seal Washer 7001050425: Crafted from oil-resistant rubber and metal, with a multi-layer sealing design to prevent oil leakage even under high load and vibration; perfectly matched to JC70B drawworks dimensions.

• ZJ45 Roller Square Filling Φ89: Machined from 42CrMo alloy steel, with high wear resistance and impact resistance; the square design ensures stable installation and optimal support for the roller system.

• Ventilated Clutch Friction Plate LT500×250T: Features a ventilated structure for heat dissipation, reducing wear caused by high temperatures; the friction surface is made of high-friction material to ensure reliable power transmission.

• Quick Self-Sealing High Pressure Connector 1″×35MPa: Made of 35CrMo alloy steel for high pressure resistance; the self-sealing design ensures tight connection without leakage, even in high-vibration environments.

Applicable Working Conditions

Maintenance & Care Suggestions

Proper maintenance is key to extending the service life of mechanical parts and reducing replacement costs. Here are practical, easy-to-follow suggestions tailored to our products:

• Regular Inspection: Check hydraulic components (e.g., ZJ70D Spring Safety Valve SCA28X-16T, Quick High Pressure Connector) and sealing parts (e.g., O-Ring 15X2.63 5300100043) every 80 operating hours; replace worn or damaged parts in time to avoid system failure.

• Cleaning & Lubrication: Keep ZJ45 Roller Square Filling Φ89, clutch friction plates, and bushings clean; apply appropriate lubricating oil (matching the equipment manual) to reduce friction and prevent rust and wear.

• Storage Requirements: Store parts in a dry, ventilated, and dust-free warehouse; avoid direct sunlight and contact with corrosive substances (especially electrical components and sealing parts). For high-pressure connectors and valves, store them in a cool, moisture-free environment to maintain their performance.

• Installation Notes: Ensure parts are installed correctly according to the equipment manual; avoid forced installation (e.g., aligning ZJ70 Main Carriage Bolt M42/106.03.10.11 properly to prevent thread damage). For safety valves, calibrate the pressure before installation to ensure accurate operation.

• Filter & Electrical Maintenance: Regularly replace filter elements (e.g., FAX-100×10, 26560145) to ensure the cleanliness of hydraulic oil and fuel; check control cables (DQ70BSD 9704092100) for damage and tight connections to avoid electrical failures.

On-Site Fault Maintenance Cases

Here are 3 real on-site maintenance cases, showing how our parts solve practical problems for customers, reduce downtime, and improve equipment performance:

Case 1: Safety Valve Failure in ZJ70D Drilling Rig

A customer’s ZJ70D drilling rig experienced hydraulic system overpressure due to a faulty non-original spring safety valve, leading to frequent shutdowns. We supplied our ZJ70D Spring Safety Valve SCA28X-16T (1.2MPa), which is calibrated to the exact pressure requirement. After replacement, the valve automatically released excess pressure, preventing system damage and reducing downtime by 80%.

Case 2: Oil Leakage in JC70B Drawworks

An oilfield’s JC70B drawworks had serious oil leakage from the seal washer, resulting in reduced system pressure and inefficient operation. We provided the JC70B Drawworks Seal Washer 7001050425, which is perfectly matched to the drawworks components. After installation, the oil leakage problem was completely solved, and the drawworks operated continuously for 450 hours without further issues.

Case 3: Clutch Slippage in ZJ40 Drilling Rig

A ZJ40 drilling rig’s clutch experienced slippage due to worn friction plates, affecting winch operation. We supplied the Ventilated Clutch Friction Plate LT500×250T, which features a heat-dissipating design and high-friction material. After replacement, the clutch engaged smoothly, eliminating slippage and improving winch efficiency by 35%.
