Our target users are segmented into three key groups: 1) Oil drilling companies operating ZJ-series and DQ70-series rigs, requiring durable drilling bits, hydraulic components, and brake devices; 2) Industrial maintenance teams responsible for hydraulic systems, electric motors, and filtration equipment, needing reliable replacement parts to minimize downtime; 3) Procurement departments of manufacturing and drilling enterprises, seeking cost-effective, high-quality spares that meet API (American Petroleum Institute), ISO 9001, and GB (Chinese National Standards) requirements. All our parts are designed to extend equipment service life, reduce maintenance frequency, and ensure safe, continuous operation.

Product Introduction & Functional Description

1. Drilling Rig Core Components

Tailored for ZJ-40, ZJ-45, ZJ-50DB, ZJ-70DB, and ZJ70PS drilling rigs, this category includes components that drive drilling efficiency and safety. Key products: main drum assembly Z03010000070AA (supports heavy-load hoisting operations in rigs), Inserted Carbide Roller Bit 12-1/4″ HJT517GK (high wear resistance for drilling in medium-hard rock formations), Steel Tooth Roller Bit 17-1/2″ GJT115GC (ideal for soft to medium rock with efficient cutting performance), and axial piston pump ZJ50DB 25SCY14-1B (delivers stable hydraulic power to rig systems). These parts are engineered to withstand high pressure, heavy loads, and the harsh conditions of drilling sites.

2. Filtration Components

Essential for protecting industrial equipment from impurity damage, this range includes suction, fuel, and hydraulic filters. Key models: Oil suction filter DQ70 ISV40-160×80MC 2.4.02.007 (filters contaminants from hydraulic oil to prevent wear in DQ70-series rig hydraulic systems), Fuel Filter 1R-0755 MODEL C32 (removes dirt and water from fuel to protect engine components), Ctype air filter DQ70C-G3/4A 2.4.02.450 (filters airborne dust to extend the life of DQ70C rig engines), and HYDRAULIC FILTER BT287 (for hydraulic tanks/charge pumps, ensuring clean hydraulic fluid for system stability). These filters feature high dirt-holding capacity and precise filtration to reduce equipment wear.

3. Hydraulic & Pneumatic Components

Critical for the smooth operation of hydraulic systems in rigs and industrial machinery, this category includes valves, pumps, cylinders, and seals. Key products: Hydraulic control valve ZJ70 (regulates hydraulic pressure in ZJ70 rig systems with high precision), Brake device ZJ-70 plunger pump 80SGY14-1B (provides reliable braking force for ZJ-70 rigs), steering cylinder 9253602 and Z02030900002AA (ensures smooth steering of rig components), Combined seal ZJ70DB FY-100Y (prevents hydraulic oil leakage in ZJ70DB rig systems), and High pressure connector and backing ring BX158 (ensures leak-proof connection of high-pressure hydraulic lines). These components deliver stable performance, reduce oil waste, and prevent system failures.

4. Mechanical & Electrical Components

This range covers bearings, fasteners, electric motors, and sensors that form the foundation of industrial equipment. Key products: Bearing NU2222EM and 430104003204400000 (support rotating components with high load-bearing capacity), bolt AF300307-010108 and nut DQ70BSD 9701100015 (securely fasten equipment parts with high strength), ELECTRIC MOTOR FOR HYDRUALIC COOLING FAN 15KW 380V 50HZ (Part Number: 3101030320, cools hydraulic systems to prevent overheating), and Inclinometer GE-MWD drive lower end line plug 981990 (ensures accurate inclination measurement for drilling operations). These parts are precision-machined to ensure dimensional accuracy and long service life.

Structural Features

All our spare parts are designed with durability, compatibility, and performance in mind, using high-quality raw materials and advanced manufacturing processes: Drilling bits (HJT517GK, GJT115GC) adopt carbide or steel tooth materials, with optimized tooth profiles to enhance drilling efficiency and wear resistance; Hydraulic components (ZJ70 hydraulic control valve, 80SGY14-1B plunger pump) feature precision-machined valve cores and sealed structures, ensuring leak-proof performance and stable pressure control; Filtration components (ISV40-160×80MC, 1R-0755) use multi-layer filter media, providing high filtration efficiency and strong dirt-holding capacity; Mechanical parts (NU2222EM bearings, AF300307 bolts) undergo heat treatment to improve hardness and wear resistance. Every part is manufactured to OE specifications, ensuring seamless installation without modifications.

Applicable Working Conditions

Our spare parts are engineered to adapt to the harshest industrial working conditions, including: Oil drilling sites (high dust, high temperature, high pressure, and corrosive mud), outdoor construction sites (extreme temperature fluctuations from -20℃ to 70℃), industrial workshops (constant vibration and heavy loads), and offshore drilling platforms (high humidity and salt corrosion). For example, the DQ70 ISV40-160×80MC oil suction filter maintains performance in dusty drilling environments; the ZJ-70DB hydraulic station oil cooler SL-307 effectively cools hydraulic fluid in high-temperature operations; and the Inserted Carbide Roller Bit HJT517GK withstands the impact of hard rock formations. 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: DQ70 Rig Hydraulic System Failure

A drilling company reported that their DQ70 rig’s hydraulic system was operating sluggishly, with frequent pressure drops. On-site inspection revealed that the ISV40-160×80MC oil suction filter was severely clogged with mud and metal impurities, restricting oil flow. We replaced it with our OE-compatible filter, which has a high dirt-holding capacity and precise filtration. After replacement, the hydraulic system pressure stabilized, and the rig returned to normal operation—reducing unplanned downtime by 85% and avoiding costly engine damage.

Case 2: ZJ-70DB Rig Brake System Malfunction

A drilling team noticed that the brake device of their ZJ-70DB rig was failing to hold load effectively, posing a safety risk. Inspection showed that the brake pads ZJ40PS Kopen KQ-21 were worn beyond the safe limit, and the Combined seal FY-100Y was leaking hydraulic oil. We supplied matching brake pads and seals, which were installed without modifications. After maintenance, the brake system regained full functionality, ensuring safe hoisting operations and preventing potential accidents.

Case 3: Fuel System Contamination in ZJ50DB Rig

A ZJ50DB rig experienced frequent engine stalling, which was traced to contaminated fuel clogging the injection system. The original Fuel Filter 1R-0755 had failed to filter out water and dirt. We replaced it with our high-quality 1R-0755 filter, which features a water separation function and high filtration precision. After replacement, the engine ran smoothly, and there were no further stalling issues—extending the engine’s service life and reducing maintenance costs.

Maintenance & Care Suggestions

To maximize the service life of our spare parts and ensure optimal equipment performance, we recommend the following practical maintenance practices:

• Filtration components (ISV40-160×80MC, 1R-0755, BT287): Check monthly for clogging (more frequently in dusty or harsh environments). Replace filters when the pressure difference exceeds 0.25MPa, and clean the filter housing to remove accumulated impurities.

• Hydraulic components (ZJ70 control valve, 80SGY14-1B plunger pump, FY-100Y seals): Inspect quarterly for leaks. Use compatible hydraulic oil and replace seals every 12 months (or earlier if wear is detected). Avoid over-tightening connections to prevent seal damage.

• Drilling bits (HJT517GK, GJT115GC): Inspect after each drilling shift for tooth wear or damage. Clean bits thoroughly to remove rock debris, and store in a dry environment to prevent corrosion. Replace bits when tooth wear exceeds 30% to maintain drilling efficiency.

• Mechanical & electrical parts (NU2222EM bearings, 3101030320 electric motor): Lubricate bearings every 6 months with high-temperature lubricating grease. Check electric motor wiring for loose connections, and clean the motor housing regularly to prevent overheating.
