SJ PETRO Hydraulic System Replacement Parts: 852XBAKP-F6XS PTO, V20-1P13P-11D20L Blade Pump

Professional Hydraulic Components for SJ PETRO Drilling Hydraulic System

This complete range of hydraulic spare parts is custom-designed and fully compatible exclusively with SJ PETRO drilling rig hydraulic systems, covering power take-off devices, hydraulic pumps, control valves, pipeline assemblies, oil tank components, brake system parts, and explosion-proof electrical accessories. These parts target the precise needs of oilfield hydraulic maintenance engineers, drilling rig fleet managers, procurement specialists for oilfield equipment, and field repair technicians — solving core pain points such as hydraulic pressure loss, valve body leakage, pump body wear, pipeline cracking, brake system failure, and unplanned drilling downtime caused by inferior aftermarket parts. Every component is manufactured in strict accordance with SJ PETRO OEM specifications, API 13D hydraulic system standards, and ISO 9001 quality management certification, adopting proprietary precision casting and pressure testing processes to ensure zero leakage, stable pressure output, and long-lasting performance in harsh oilfield drilling environments.

Core Purpose Statement

These SJ PETRO dedicated hydraulic parts serve as direct OEM replacements for routine hydraulic system maintenance, emergency fault repair, and comprehensive system overhauls. Their core mission is to restore normal hydraulic pressure transmission, seal all hydraulic circuit interfaces, stabilize the operation of power and control components, ensure the reliable operation of brake and steering auxiliary systems, and maintain the SJ PETRO hydraulic system in optimal working condition. By resolving common hydraulic failures such as leakage, pressure instability, and component jamming, these parts reduce maintenance costs, extend the service life of the entire hydraulic system, and guarantee safe and continuous drilling operations.

Structured Product Description

1. Product Introduction

This hydraulic parts portfolio covers all key components of the SJ PETRO drilling hydraulic system: including 852XBAKP-F6XS 5000950002 PTO, Z-series hydraulic pipeline assemblies (latch locking cylinder lines, multi-bank valve lines, steering aided cylinder lines, tong cylinder lines), V20-1P13P-11D20L 4900550076 blade pump, FM3-08P-130-150-10 relief valve, CIT-06-04-50 check valve, G21-69-B steering distribution valve, series of intake/working/needle valves, EF6-80 air filter, Z07170000066AA hydraulic oil tank, brake pump pipe joints, YB100L2-4 explosion-proof motor, brake system connecting parts, and PHP1050R2 axial piston pump. Each part undergoes 100% pressure testing (up to 160MPa) and dimensional inspection, with a field-proven service life of 3200 operating hours — 1100 hours longer than ordinary aftermarket hydraulic parts. All parts feature matching OEM part numbers for quick identification and hassle-free installation.

2. Function Description

• Power Components: 852XBAKP-F6XS PTO transmits engine power to hydraulic pumps; V20-1P13P-11D20L blade pump and PHP1050R2 axial piston pump provide stable hydraulic power, ensuring continuous pressure supply for the drilling system.

• Control Valves: Relief valves, check valves, and distribution valves regulate hydraulic pressure, control flow direction, prevent oil backflow, and protect the hydraulic system from overpressure damage.

• Pipeline & Tank Components: Z-series hydraulic pipelines connect each hydraulic actuator; hydraulic oil tank stores and cools hydraulic oil, ensuring clean and stable oil circulation.

• Brake & Auxiliary Parts: Brake pump joints, explosion-proof motors, and connecting sleeves ensure reliable operation of the drilling rig brake system; air filters keep hydraulic oil clean and reduce component wear.

3. Structural Features

All hydraulic components adopt high-strength ductile iron casting for valve bodies and pump casings, with precision-honed inner surfaces to reduce friction and leakage; hydraulic pipelines use thick-walled seamless steel pipes with anti-corrosion coating, resistant to high pressure and vibration; sealing components use oil-resistant nitrile rubber and polyurethane materials, with a compression set of less than 0.05mm under long-term pressure. Precision-machined mating surfaces have dimensional tolerances controlled to ±0.01mm, ensuring a tight fit and zero leakage. The modular design of valves and pumps allows for quick on-site replacement, cutting maintenance time by 70 minutes per repair.

4. Applicable Operating Conditions

These parts are specially developed for SJ PETRO drilling rig hydraulic systems, suitable for onshore oilfield drilling, well workover, and drilling rig auxiliary operations. They operate stably in ambient temperatures ranging from -38°C to 92°C, withstand continuous vibration, mud erosion, and crude oil corrosion, and comply with API 13D drilling hydraulic system standards and GB 3836 explosion-proof electrical standards. All hydraulic components are rated for a maximum working pressure of 160MPa, suitable for all-weather harsh oilfield environments.

5. Maintenance & Servicing Recommendations (Field Engineer Practical Tips)

• Pump Maintenance: Inspect V20-1P13P-11D20L blade pump and PHP1050R2 piston pump every 500 operating hours; replace worn bearings and seals, and replenish special hydraulic oil to prevent cavitation.

• Valve Inspection: Check relief valves, check valves, and control valves every 400 operating hours; clean valve cores, remove impurities, and replace faulty valves to avoid pressure instability.

• Pipeline & Tank Care: Inspect Z-series hydraulic pipelines for cracks or leaks monthly; clean the hydraulic oil tank and replace EF6-80 air filter every 800 operating hours to keep oil clean.

• Brake System Check: Test brake pump joints and explosion-proof motors every 300 operating hours; tighten loose joints and check motor insulation to ensure brake reliability.

• Seal Replacement: Replace all hydraulic seals every 1200 operating hours; use special installation tools to avoid seal damage during assembly.
