Function Description

Each of our spare parts is engineered to perform a specific, critical function that directly impacts the safety, efficiency, and longevity of your equipment. Below is a simple breakdown of core functions for key product categories:

1. Temperature & Electronic Components

The Temperature Sensor 2566453 CATC18 monitors the operating temperature of CATC18 engines in real time, sending accurate data to the control system to prevent overheating and engine damage. The Electronic Balance Digital DT-1000 0.2g provides precise weight measurement for industrial components, ensuring accurate assembly and equipment balance—critical for reducing vibration and wear.

2. Seals & Gaskets

O-Rings (530301012000070007, 5303100510 160×7) and Valve Seals 6N7174 create airtight and watertight seals in hydraulic, pneumatic, and fluid systems, preventing leakage that can lead to pressure loss and equipment failure. The Tracheal Bundle Sealant 6PKG.102 20hole ensures secure sealing of air and gas pipelines, reducing energy waste and improving system efficiency.

3. Valves & Fittings

The Two-Position Three-Way Pneumatic Control Valve 3WP6B5X/N controls the direction of air flow in pneumatic systems, enabling quick and reliable switching of equipment functions (e.g., brake activation, winch operation). The Crane ZJ-70D Superimposed Two-Way Overflow Valve Z2DBK6VC2-1X/210V protects hydraulic systems from overpressure, preventing damage to pumps and cylinders.

4. Engine & Brake Components

The Engine Repair Kit 6V8023 includes all necessary components (gaskets, seals, hardware) to repair and maintain engines, reducing the need for separate part sourcing. The Brake Device ZJ-70D Filter Element FXB 400*30 removes contaminants from brake fluid, ensuring smooth braking performance and extending the life of brake components in ZJ-70D rigs.

Structural Features

Our spare parts are designed with durability, compatibility, and ease of use in mind, featuring structural advantages that make them stand out in harsh industrial environments. These features are engineered to solve real-world problems for our users:

1. OEM-Level Compatibility

All parts are manufactured to match the exact dimensional and performance specifications of original equipment (OEM standards). For example, the Copper Sleeve-I ZX01.01.02 for Drawworks JC70DB is precision-machined to fit seamlessly with the original drawworks, eliminating the need for modifications during installation and reducing the risk of mismatched components.

2. High-Durability Materials

Critical components are made from high-grade materials to withstand extreme conditions: friction plates (23010436, 23041786) use wear-resistant alloy to extend service life by 35% compared to standard plates; O-rings are made from nitrile rubber (NBR) for excellent oil and temperature resistance (-40℃ to 120℃); and sprockets (P3500010AA) are heat-treated for enhanced strength and corrosion resistance.

3. User-Friendly Design

Many parts feature modular and easy-to-install designs to reduce maintenance time. The Engine Repair Kit 6V8023 comes with pre-sorted components and clear installation instructions, allowing maintenance teams to complete repairs quickly. The Flushing Assembly DQ70BSD 9702036000 52MPa is designed for easy connection to DQ70BSD rigs, simplifying system flushing and maintenance.

4. Safety-Centric Construction

Components like the Gate Assembly FZ897.21.09.00 and Back Vise Guide Sleeve DQ70BS T754020523 feature reinforced structures to withstand high pressure and heavy loads, ensuring safe operation in drilling and industrial settings. The Brake Lever Assembly ZJ70DB YK02-01 is designed with an ergonomic handle for easy operation, reducing operator fatigue and improving safety.

Applicable Working Conditions

Our spare parts are engineered to perform reliably in the most challenging industrial environments, making them suitable for the following scenarios:

• Oil Drilling Sites: Compatible with ZJ30C, ZJ45, ZJ50D28, ZJ70DB, and DQ70BSD drilling rigs, operating in high-temperature (up to 130℃), high-pressure (up to 52MPa), dusty, and humid environments—ideal for onshore and offshore drilling operations.

• Engine & Power Systems: Suitable for CATC18 engines and manham diesel systems, operating in high-load, continuous-run conditions where temperature and pressure fluctuations are common.

• Heavy Industrial Facilities: Perfect for mud pumps, winches, brakes, and boiler systems (KDB-250FA) in mining, construction, and manufacturing, where equipment operates under heavy loads and harsh conditions.

• High-Vibration Applications: Components like the Retaining Ring WH-550-S16 (BOP Group) and Shaft Spacer B117C21 are designed to withstand constant vibration in rotating equipment, ensuring long-term stability and preventing component loosening.

Maintenance & Care Recommendations

Proper maintenance of spare parts is key to extending their service life and ensuring optimal equipment performance. Below are practical, easy-to-follow tips for daily use and maintenance:

1. Regular Inspection

Inspect seals (O-rings, valve seals) and hoses (Main Oil In Hose Assembly 9702010003) monthly for cracks, leaks, or wear—replace immediately if damage is found to prevent system failure. Check fasteners and retaining rings quarterly for tightness, especially in high-vibration components like winches and sprockets.

2. Cleaning & Lubrication

Clean filters (Mud Pump Group Filter IA-192/5400150038, Brake Filter Element FXB 400*30) every 3 months to remove debris and prevent clogging. Lubricate moving parts (pulley Φ1005, sprockets, angle gearbox JJX140) with high-temperature lubricating oil to reduce friction and wear.

3. Storage Guidelines

Store spare parts in a dry, clean, and temperature-controlled environment (10-25℃) to avoid rust and damage. Seals and rubber components should be stored away from direct sunlight and chemicals to prevent aging. Electronic components (DT-1000 balance, temperature sensor 2566453) should be stored in anti-static packaging to protect sensitive circuits.

4. Replacement Schedule

Follow these recommended replacement intervals: O-rings every 6-12 months (or sooner if leakage is observed); engine oil seals (5I7660) every 12 months; filters (IA-192, FXB 400*30) every 6 months or 500 operating hours; friction plates (23010436, 23041786) every 18 months.
