Function Description

Core Functions of Key Products

Every part we supply is designed to perform a critical role in keeping equipment operational, with functional advantages tailored to real-world needs:

• Bearings & Transmission: Bearings like 43011001 UN240 and 97521E GB299-86 reduce friction between moving parts, ensuring smooth power transmission with a friction coefficient of ≤0.002. The Transmission shaft L=1523 5000700068 maintains alignment even under heavy loads, preventing shaft bending and equipment jamming.

• Drilling Components: The ZJ-50/315 DB19 cylinder liner GH3161-05.21 withstands high pressure (up to 35MPa) and temperatures (up to 160°C), preventing cylinder scuffing and fluid leakage. The Elevator DDZ250 5IEU safely lifts and positions drill pipes, with a load capacity of 250 tons—meeting API 8C standards.

• Pump Parts: The Piston rod 1P102967 SPM ensures stable crankshaft operation in TWS-600S mud pumps, with a surface hardness of HRC 60-62 to resist wear. The MECHANICAL SEAL 22451-1 creates a leak-tight barrier for Mission centrifugal pumps, preventing fluid loss and protecting internal components from contamination.

• Filtration: Filters like 377-2873 pilot circuit filter and MF4003A25HB P01 MP FILTRI remove impurities (down to 5μm) from hydraulic fluid and air, reducing component wear by 40% and extending equipment service life by 25%.

• Seals & Gaskets: O-RING 568-234 NIT 90DR C6711912 and Seal 280 X 320 X 20GB/T13871-1992 provide reliable sealing in high-pressure, high-temperature environments, with a leak rate of ≤0.01 cc/min—far below industry standards of 0.05 cc/min.

• Electrical & Controls: The Oil Temperature Sender DC24V 789802-00-0180 monitors ZJ-20 air system temperature with ±1°C accuracy, triggering alerts for overheating and preventing system damage. The Control valve SM HH8S372WV regulates fluid flow with precision, ensuring consistent equipment performance.

Structural Features

Material & Design Advantages

Our parts are built to last, with structural features that address the harsh conditions of industrial and drilling environments:

1. High-Performance Materials

We use industry-grade materials tailored to each component’s function: GH3161 alloy (for ZJ-50/315 cylinder liners and guides) offers exceptional corrosion resistance to acid drilling fluids; high-carbon chromium steel (for bearings 43011001 UN240 and 234GB276-64RG) ensures fatigue strength and wear resistance; Nitrile (NIT 90DR) for O-rings provides flexibility and oil resistance; and 40Cr steel (for Oil filling connector 4272-343-1-01) delivers high tensile strength. All raw materials pass ISO 9001:2015 certification, with a material qualification rate of 100%.

2. Precision Engineering

All parts are manufactured using CNC machining technology, with a dimensional tolerance of ±0.004mm—ensuring perfect compatibility with OEM equipment. For example, the Piston rod 1P102967 SPM has a surface finish of Ra ≤ 0.6μm, reducing friction and wear; the INTEGRAL CROSSOVER 2″ FIG 1502 MXM 1502MX2M features precision-threaded connections for leak-proof assembly; and the Bearing 97521E GB299-86 has a hardened raceway to extend service life.

3. Durability & Safety Design

Many parts feature reinforced designs for harsh conditions: the HAMMERSEAL UNION COMPLETE ASSY.SIZE.16″ PS160A has a heavy-duty steel body to withstand high pressure (up to 16,000 psi); the EMERGENCY CALIPER PSZ75A-2-00 is designed for quick emergency braking, with a response time of ≤0.5 seconds; and the Vibrating screen box 503 200 mesh HDF-5 has a reinforced frame to resist vibration and extend screen life.

Applicable Working Conditions

Our parts are rigorously tested to perform in the most demanding industrial and drilling environments, covering key scenarios:

• Oilfield Drilling: Suitable for ZJ-50/315 drilling rigs, SPM TWS-600S mud pumps, NOV TDS-10SH top drives, and Mission centrifugal pumps. Withstands high pressure (up to 35MPa), corrosive drilling fluids, extreme temperatures (-40°C to 160°C), and heavy vibration.

• Industrial Manufacturing: Compatible with Doosan engines, Shangair compressors, and general industrial pumps. Adapts to dusty, humid, and continuous operation environments, ensuring reliable performance in factories and processing plants.

• High-Pressure Hydraulic Systems: Parts like high-pressure hose 10 meters ZQ203-100 (working pressure up to 25MPa) and 4807100024-NXQ accumulator bladder are designed for hydraulic systems in heavy machinery, withstanding frequent pressure cycling.

• Hazardous Zones: Electrical components (e.g., Oil Temperature Sender 789802-00-0180) meet IP65 waterproof and dustproof standards, suitable for onshore and offshore drilling sites with flammable or corrosive materials.

Maintenance & Care Recommendations

Proper maintenance of our parts will maximize their service life, reduce replacement costs, and ensure equipment safety. Below are practical, easy-to-follow recommendations based on industry best practices:

• Bearings: Lubricate bearings (43011001 UN240, 97521E GB299-86) with API-grade grease every 800 operating hours. Check for abnormal noise or vibration—this may indicate misalignment or wear. Replace bearings if they show signs of rust or pitting.

• Seals & Gaskets: Inspect O-rings (568-234 NIT 90DR, GB3452.1-82) and gaskets (Doosan 65.96601-0046A) every 500 operating hours for cracks, hardening, or deformation. Clean sealing surfaces before installation to avoid debris affecting performance. Replace seals after 3,000 operating hours or if leakage is detected.

• Filters: Replace pilot circuit filter 377-2873 and MP FILTRI MF4003A25HB P01 when pressure differential exceeds 0.25MPa. Clean pre-filter AmAir 300-2″ 24X20 every 1,000 hours to maintain airflow and prevent clogging. Use only genuine filters to avoid damaging hydraulic or engine systems.

• Piston Rods & Cylinder Liners: Clean piston rods (1P102967 SPM, GH3161-28.05) and ZJ-50/315 DB19 cylinder liner regularly to remove debris. Inspect for scratches or wear—polish minor scratches to prevent seal damage. Replace cylinder liners if they show signs of excessive wear (wall thickness ≤5mm).

• General Care: Store parts in a dry, clean, and ventilated area, away from direct sunlight and moisture. Apply anti-rust oil to metal parts (transmission shafts, bearings) for long-term storage. For electrical components, avoid exposure to water or corrosive fumes.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases, providing practical guidance for equipment maintenance and part replacement—helping you quickly diagnose issues and minimize downtime:

Case 1: SPM TWS-600S Mud Pump Crankshaft Instability

Equipment Model: SPM TWS-600S Mud Pump
Fault Phenomenon: The pump experienced excessive vibration, reduced pressure output, and abnormal noise from the crankshaft area.
Root Cause: The original piston rod (non-genuine) had uneven surface wear and insufficient hardness, leading to crankshaft misalignment and increased friction.
Solution: Replaced with our Piston rod 1P102967 SPM, which features a hardened surface (HRC 60-62) and precision machining. After installation, vibration was reduced by 55%, pressure output returned to standard, and the pump operated smoothly. The piston rod has since lasted 4,200 operating hours—2.8x longer than the original non-genuine part.

Case 2: ZJ-50/315 Drilling Rig Cylinder Leakage

Equipment Model: ZJ-50/315 Drilling Rig (DB19 Cylinder System)
Fault Phenomenon: Fluid leakage from the cylinder liner, leading to reduced drilling efficiency and increased fluid consumption.
Root Cause: The original cylinder liner was made of low-grade material, lacking corrosion resistance to acid drilling fluid, resulting in wear and leakage after 2,500 operating hours.
Solution: Installed our ZJ-50/315 DB19 cylinder liner GH3161-05.21, crafted from GH3161 alloy for corrosion and wear resistance. The cylinder passed a 72-hour pressure test (35MPa) without leakage, and service life is expected to reach 8,000 operating hours—3.2x longer than the original part. Drilling efficiency was restored, and fluid consumption decreased by 30%.

Case 3: Mission Centrifugal Pump Leakage

Equipment Model: Mission Centrifugal Pump (Model 648414308)
Fault Phenomenon: Severe fluid leakage from the pump shaft, causing environmental hazards and reduced pump performance.
Root Cause: The original mechanical seal (22451-1) was worn and had a damaged diaphragm, failing to maintain a leak-tight seal.
Solution: Replaced with our MECHANICAL SEAL FOR CENTRIFUGAL PUMP 22451-1 MISSION H224511A, which features a reinforced diaphragm and corrosion-resistant materials. After replacement, leakage was eliminated, and the pump’s flow rate and pressure returned to standard. The seal has operated reliably for 3,800 hours, with no signs of wear.
