Structural Features

All our spare parts are designed with durability, compatibility, and performance at the forefront, using high-quality raw materials and advanced manufacturing processes: Hydraulic components (AH36001-0501B0 hydraulic cylinder, BK-F-G3 globe valve) feature precision-machined cylinders and valve cores, with sealed structures that ensure leak-proof performance and stable pressure resistance; Filtration components (1R0755 filter element, HBX40×10 oil filter) use multi-layer filter media, providing high filtration efficiency (up to 10μm for HBX40×10) and strong dirt-holding capacity; Mechanical connections (DQ70BS rail pin, GB5780-86 bolt) undergo heat treatment to improve hardness and wear resistance, ensuring they can withstand heavy loads and frequent use; Electrical accessories (360404 oil pressure sensor, SK-2000 CAN bus connector) adopt high-precision sensing and transmission technology, ensuring accurate data and stable performance. Every part is manufactured to OE specifications, so no modifications are needed during installation.

Applicable Working Conditions

Our spare parts are engineered to adapt to the harshest industrial working conditions, including: Onshore and offshore oil drilling sites (high dust, high temperature, high pressure, and corrosive mud); Industrial workshops (constant vibration, heavy loads, and high humidity); Outdoor construction sites (extreme temperature fluctuations from -25℃ to 75℃); and Oilfield auxiliary facilities (high-pressure fluid environments). For example, the FA3 hose assembly F381 CACF 151508-280 maintains performance in high-pressure (up to 31.5MPa) and high-temperature drilling environments; the 1R0755 filter element resists clogging in dusty air compressor operations; and the ZJ-70DB disc brake safety pliers disc spring PSZ75-2-08 ensures reliable braking even in high-vibration winch operations. All parts comply with industry-specific environmental and safety standards for their respective applications.

We supply the following spare parts:

On-Site Fault Maintenance Cases

Case 1: ZJ-70DB Rig Winch Brake Malfunction

A drilling company reported that the winch of their ZJ-70DB rig was failing to hold load securely, posing a safety risk. On-site inspection revealed that the disc brake safety pliers disc spring PSZ75-2-08 was fatigued and deformed, reducing braking force. We supplied a matching OE-compatible disc spring, which was installed without modifications. After replacement, the winch brake regained full functionality, ensuring safe hoisting operations and preventing potential accidents.

Case 2: F-1300 Mud Pump Hydraulic Cylinder Leakage

A drilling team noticed severe hydraulic oil leakage from their F-1300 mud pump, causing reduced pump efficiency and oil waste. Inspection showed that the hydraulic cylinder (original part) was worn, and the O-ring 530301011850070007 was damaged. We provided the AH36001-0501B0 hydraulic cylinder with matching O-rings, which were installed to OE specifications. After maintenance, the mud pump operated without leakage, restoring full efficiency and reducing oil consumption by 30%.

Case 3: TU-FL1000 Air Compressor Overheating

An oilfield auxiliary facility reported that their TU-FL1000 air compressor was overheating frequently, leading to automatic shutdowns. Inspection found that the 1R0755 filter element was severely clogged with dust, restricting air flow and causing overheating. We replaced it with our high-quality 1R0755 filter element, which has a high dirt-holding capacity. After replacement, the air compressor’s operating temperature returned to normal, and there were no further shutdowns—ensuring continuous operation of auxiliary equipment.

Maintenance & Care Suggestions

To maximize the service life of our spare parts and ensure optimal equipment performance, we recommend the following practical maintenance practices that align with industrial operational needs:

• Filtration components (1R0755, HBX40×10, RFA-400×30F-Y): Check monthly for clogging (more frequently in dusty or harsh environments). Replace filters when the pressure difference exceeds 0.3MPa, and clean the filter housing to remove accumulated impurities. Use only compatible filter media to avoid damaging equipment.

• Hydraulic components (AH36001-0501B0 cylinder, BK-F-G3 globe valve, F381 CACF hose): Inspect quarterly for leaks. Replace O-rings and seals every 12 months (or earlier if wear is detected). Use hydraulic oil that meets API standards to maintain system performance and prevent component corrosion.

• Mechanical connections (DQ70BS rail pin, GB5780-86 bolt): Check monthly for loose connections or wear. Tighten bolts to the recommended torque, and replace pins or bushings if there is excessive play. Apply anti-rust lubricant to metal parts to prevent corrosion in humid or corrosive environments.

• Electrical & instrument accessories (360404 oil pressure sensor, SK-2000 connector): Inspect bi-annually for loose wiring or sensor drift. Calibrate sensors and instruments once a year to ensure accurate data. Store electrical spare parts in a dry, dust-free environment to prevent damage.
