Mud Pump Group ZJ-30C, Fuel Filter BF5800, Three-Position Four-Way Reversing Valve 34JR6-L8

Introduction

This document focuses on a full range of precision-manufactured spare parts specifically engineered for drilling rigs (ZJ-30C, ZJ45, ZJ50L, ZJ70, ZJ70L, ZJ50/3150DZ) and supporting industrial equipment (Caterpillar C32, Detroit 8V-71, Boiler WNS2-1.25-5Y, Horizontal Sand Pump SB3*4J-15k). Covering core components such as Mud Pump Group ZJ-30C, Fuel Filter BF5800 (for Detroit 8V-71), Three-Position Four-Way Reversing Valve 34JR6-L8, and Brake Device ZJ70L Disc Brake Hydraulic Station Elastic Coupling YZBS-120LD-2, our products are designed to solve the most critical pain points of target users in oil and gas drilling, equipment maintenance, and industrial operations.

Our target users include oilfield drilling companies, drilling rig maintenance teams, industrial equipment procurement departments, and heavy machinery service providers. We precisely address three core segmented needs: 1) 100% compatible spare parts for quick replacement of worn components, minimizing unplanned equipment downtime and emergency repair costs; 2) High-pressure, high-temperature resistant parts that perform reliably in harsh drilling and industrial environments (e.g., high-pressure drilling, dusty construction sites); 3) Cost-effective, long-service-life components that reduce replacement frequency and lower overall operational costs. All products comply with international industrial standards (ISO 9001:2015 quality management system, API Spec 7K for drilling equipment, GB91-86 for fasteners) and are produced using precision CNC machining and advanced heat treatment technology, ensuring a dimensional tolerance of ±0.01mm and a service life 22% longer than industry averages.

Core Purpose

The core purpose of our spare parts is to provide a one-stop, reliable solution for drilling rigs and industrial equipment, ensuring continuous, safe, and efficient operation while reducing operational and maintenance costs. Each component—from small fasteners (GB91-86 Cotter Pin, Round Nut 50LDB 39×1.5) to large core assemblies (Mud Pump Group ZJ-30C, Horizontal Sand Pump SB3*4J-15k)—is designed to match original equipment specifications perfectly, eliminating compatibility issues that often lead to equipment failure, costly repairs, and project delays. For example, the High-Pressure Manual Gate Valve Z23Y-35 DN80 is engineered to withstand a maximum working pressure of 35MPa, ensuring leak-free operation in ZJ70 series drilling rig hydraulic systems; the Fuel Filter BF5800 (for Detroit 8V-71) features a filtration precision of 4μm, protecting engine components from wear and reducing engine failure rates by 30%. By providing such high-performance parts, we help users cut unplanned downtime by 38%, reduce maintenance costs by 30%, and improve overall equipment operational efficiency by 27%.

Structural Features

Design Advantages of Core Components

Our products adopt advanced structural design to enhance performance, durability, and compatibility, addressing the common pain points of ordinary parts such as easy wear, poor sealing, and short service life:

• Drilling Core Assemblies: The Mud Pump Group ZJ-30C adopts a double-cylinder, single-acting structure, which evenly distributes load and reduces wear on internal components. The SAVER SUB 4-1/2″ FOR KELLY features a NC50 connection design, ensuring a tight and reliable connection with the kelly, preventing disconnection during high-torque drilling.

• Valves & Hydraulic Components: The Three-Position Four-Way Reversing Valve 34JR6-L8 uses a spool valve structure with a hard chrome-plated surface (thickness 0.09mm), improving wear resistance and corrosion resistance. The High-Pressure Manual Gate Valve Z23Y-35 DN80 adopts a wedge-shaped gate design, ensuring tight sealing and easy operation even under high pressure.

• Brake Components: The Brake Device ZJ70L Elastic Coupling YZBS-120LD-2 uses a rubber damping structure, which effectively absorbs vibration and reduces noise (noise ≤ 70dB). The Brake Pad Shaft Pin SY-PS-1650/720 is made of high-strength alloy steel, with a tensile strength of 800MPa, ensuring it can withstand high braking forces.

• Filters & Seals: The Fuel Filter BF5800 adopts a multi-layer filtration structure, with a filter efficiency of 99.8% for particles larger than 4μm. The O-Ring DQ70 2.4.51.003 is made of high-temperature resistant nitrile rubber, which can work normally at -40℃ to 125℃, ensuring reliable sealing in high-temperature hydraulic systems.

Maintenance & Care Recommendations

Proper maintenance and care can extend the service life of spare parts, reduce maintenance costs, and ensure stable equipment operation. We provide professional recommendations based on industry best practices and product characteristics, serving as a clear technical reference for users:

• Regular Inspection: Conduct a comprehensive inspection of key components every 350 operating hours. For example, check the wear of the Brake Pad Shaft Pin SY-PS-1650/720 (replace when wear exceeds 2mm), inspect the sealing performance of the O-Ring DQ70 2.4.51.003 (replace if there is oil leakage), and check the pressure gauge YTN-60ZT(1.6MPa)/380 for accuracy (calibrate if error exceeds ±1.5%).

• Lubrication Maintenance: Apply appropriate lubricating oil to transmission components (such as Oil Guide Swivel Joint R019 and Drive Ring 515867) every 120 operating hours. Use lubricating oil that meets API GL-5 standard to ensure good lubrication and reduce wear.

• Storage Requirements: Store spare parts in a dry, ventilated, and clean warehouse, with a temperature of 0-25℃ and relative humidity ≤ 55%. Avoid direct sunlight and contact with corrosive substances (such as seawater, acid, and alkali) to prevent rust and damage. For electrical parts (such as starters and current transformers), store them in sealed packaging to avoid moisture.

• Replacement Standards: Replace parts in accordance with service life and wear standards. For example, the service life of the Fuel Filter BF5800 is 120 operating hours, and it should be replaced in time to avoid fuel blockage; the service life of the Mud Pump Group ZJ-30C internal components is 8000 operating hours, and regular inspection and maintenance should be carried out to ensure its performance.
