Covering core components such as Monocular BOP DQ70BSC 2210170197 70MPa, Gear Pump P37 3S8022, Closed Pliers Repair Kit ZJ50 BX-00C, and Insert Carbide Roller Bit 8-1/2″ HJ517G, our products are designed to solve the critical pain points of target users in oil and gas drilling, industrial equipment operation, and maintenance.

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 or damaged components, minimizing unplanned equipment downtime and emergency repair costs; 2) High-pressure, corrosion-resistant, and wear-resistant parts that ensure reliable operation in harsh drilling and industrial environments; 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, GB/T standards for hydraulic components) and are produced using precision CNC machining and advanced surface treatment technology, ensuring a dimensional tolerance of ±0.01mm and a service life 26% 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 (Nut P1200378AA, Bolt X20-08-054) to large core assemblies (Monocular BOP DQ70BSC 2210170197 70MPa, Main Carriage ZJ50LDB Valve Island 10P-18-6A-MP-R–Y-5CL) and precision parts (Control Circuit Board TJB, One-way DC Contactor SK-2Z16 K6 CCZ38-125)—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 Monocular BOP DQ70BSC 2210170197 70MPa is engineered for high-pressure drilling operations, with a maximum working pressure of 70MPa and a pressure-bearing capacity 15% higher than standard BOPs; the Gear Pump P37 3S8022 delivers a flow rate of 37L/min, ensuring stable hydraulic power supply for drilling rig systems. By providing such high-performance parts, we help users cut unplanned downtime by 45%, reduce maintenance costs by 35%, and improve overall equipment operational efficiency by 31%.

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 Insert Carbide Roller Bit 8-1/2″ HJ517G (replace when carbide insert wear exceeds 2mm), inspect the sealing performance of the C2 Sealing Ring ZJ70DB C2F015N3584 (replace if there is oil leakage), and check the Gear Pump P37 3S8022 for flow rate (calibrate if flow rate deviation exceeds ±5%).

• Lubrication Maintenance: Apply appropriate lubricating oil to transmission components (such as Gear Pumps 512601010010006000 and Bearing NU2220ECM-C3) 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 Rectifier Bridge QBK-22) and control components, store them in sealed packaging to avoid moisture and dust.

• Replacement Standards: Replace parts in accordance with service life and wear standards. For example, the service life of the Air Filter ZJ50L QUQ3-10×4 is 180 operating hours, and it should be replaced in time to ensure air filtration efficiency; the service life of the Monocular BOP DQ70BSC 2210170197 70MPa is 15000 operating hours, and regular inspection and maintenance should be carried out to ensure well control safety.
