Function Description

Each of our spare parts is designed to perform a specific, critical function that directly contributes to the overall performance and safety of your equipment. Below are the key functions of core product categories, explained in simple terms:

1. Rotary Table & Hydraulic Parts

The Adjusting Washer P1000230AA ensures precise alignment of the ZP-275 Rotary Table, preventing vibration and wear during high-speed rotation—critical for maintaining drilling accuracy. The Hydraulic Pump 3139610587 delivers stable hydraulic pressure to the Mast Hydraulic System, enabling smooth lifting and positioning of the mast in oil drilling operations.

2. Mechanical Components

Impellers (GG12137, 64056, F6021) are key components in slurry pumps and fluid handling systems, responsible for moving liquids efficiently with minimal energy loss. The Three-cylinder Crankshaft Plunger Pump FKQ1280-8 QB21-82 provides high-pressure fluid delivery for downhole drilling operations, ensuring consistent performance in high-load conditions.

3. Valves & Control Components

Two-position Three-way Air Control Reversing Valve 4900350107 controls the direction of air flow in pneumatic systems, allowing quick and reliable switching of equipment functions. The Safety Valve V74G-4GK-NMN protects hydraulic and pneumatic systems from overpressure, preventing equipment damage and ensuring operator safety.

4. Fasteners & Seals

High Strength Bolts ZJ70 PSK PY701-01-0304 are engineered to withstand extreme tension and vibration in ZJ70 rigs, ensuring components stay securely fastened even in harsh drilling environments. Sealing Rings (AZ502101020218, BKD-SR-4) prevent fluid leakage in hydraulic and pneumatic systems, maintaining system pressure and reducing maintenance frequency.

Structural Features

Our spare parts are designed with durability, compatibility, and ease of installation in mind, featuring the following structural advantages that set them apart from standard components:

1. Precision Manufacturing

All parts are produced using CNC machining and strict quality control processes, ensuring dimensional accuracy within ±0.01mm. This precision guarantees seamless compatibility with original equipment (OEM standards), eliminating the risk of mismatched components that cause equipment jams or failure.

2. High-Durability Materials

Critical components like impellers, bolts, and seals are made from high-grade materials—including carbon steel, stainless steel, and wear-resistant rubber—to withstand corrosion, high pressure, and extreme temperatures. For example, the SPM Oil Scraper Ring P101883HP uses a special alloy coating to reduce wear and extend service life by 30% compared to standard scraper rings.

3. User-Friendly Design

Many parts feature modular designs for easy installation and replacement, reducing maintenance time. For instance, the Middle and Lower Structure Repair Kit 9X6425 includes all necessary components (gaskets, bolts, seals) in one package, eliminating the need for separate part sourcing.

4. Safety-Centric Structure

Components like the Brake Device ZJ-70D Disc Brake Working Pliers Oil Cylinder Assembly KG-00 feature a double-seal structure to prevent oil leakage, ensuring reliable braking performance in emergency situations. The Front Seal RJ1114&09.17.02 is designed with a reinforced lip to withstand high pressure and prevent fluid loss.

Applicable Working Conditions

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

• Oil Drilling Sites: Compatible with ZJ30C, ZJ50, ZJ70, and DQ70BSD drilling rigs, operating in high-temperature (up to 120℃), high-pressure (up to 20MPa), and dusty environments—ideal for onshore and offshore drilling operations.

• Heavy Industrial Plants: Suitable for rotary tables (ZP-275), mast hydraulic systems, and pneumatic winches (JQH5B50*12) in mining, construction, and manufacturing facilities, where equipment operates continuously under heavy loads.

• Harsh Outdoor Environments: Seals and hoses (Flame Retardant Hose Assembly 140507021001040013, High Pressure Hose Assembly 140507020801000000) are resistant to UV radiation, moisture, and chemical corrosion, making them suitable for outdoor operations in all weather conditions.

• High-Vibration Applications: Fasteners like Socket Head Cap Screws DQ70BS B03050060081201 M6×8 feature anti-loosening designs to withstand constant vibration in rotating equipment, ensuring long-term stability.

Maintenance & Care Recommendations

Proper maintenance of spare parts is essential to extend their service life and ensure equipment performance. Below are practical, easy-to-follow recommendations for daily use and maintenance:

1. Regular Inspection

Check fasteners (bolts, nuts) monthly for tightness, especially in high-vibration components like rotary tables and pumps. Inspect seals and hoses for cracks, leaks, or wear—replace immediately if damage is found to prevent system failure.

2. Cleaning & Lubrication

Clean impellers (GG12137, 64056) and filters (Filter Element 1R-0741) every 3 months to remove debris and prevent clogging. Lubricate moving parts (bearing pinions AH36001-0309, transfer case BJX260) 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.

4. Replacement Schedule

Follow the recommended replacement intervals: Oil filters (YOTJ750-03) every 6 months or 500 operating hours; mechanical seals (SB34J) every 12 months; impellers (F6021) every 18 months (or sooner if excessive wear is observed).

On-Site Fault Repair Cases

Below are three real-world repair cases, demonstrating how our spare parts solve common equipment issues and minimize downtime. These cases are based on actual feedback from our clients in the oil drilling industry:

Case 1: ZP-275 Rotary Table Vibration Issue

Problem: A drilling company reported excessive vibration in their ZP-275 rotary table, leading to reduced drilling accuracy and increased wear on other components. Root Cause: Worn adjusting washer (original part) causing misalignment. Solution: Replaced with our Adjusting Washer P1000230AA, which features precise dimensional accuracy. Result: Vibration reduced by 40%, drilling accuracy improved, and component wear decreased significantly—downtime was limited to 2 hours.

Case 2: Mast Hydraulic System Pressure Loss

Problem: A ZJ70 rig’s mast hydraulic system experienced sudden pressure loss, preventing the mast from lifting. Root Cause: Failed hydraulic pump (original part 3139610587) due to internal wear. Solution: Installed our replacement Hydraulic Pump 3139610587, which features a reinforced internal structure. Result: System pressure restored to normal, mast operation resumed within 3 hours, and the pump has maintained stable performance for over 6 months.

Case 3: Sand Pump Leakage

Problem: A ZJ40 sand pump was leaking fluid, leading to reduced efficiency and environmental concerns. Root Cause: Damaged mechanical seal (original part). Solution: Replaced with our Sand Pump Mechanical Seal ZJ40 SB34J, which features a double-seal design for enhanced leak resistance. Result: Leakage stopped completely, pump efficiency restored, and maintenance frequency reduced by 50%.
