Product Description

Product Introduction

Our CSF-1300 general frame parts are premium OEM-equivalent components covering the pump’s full structural, power transmission, and auxiliary systems, including rack assemblies, crankshaft and pinion components, crosshead parts, multi-specification oil seals and O-rings, high-tensile bolts/nuts, safety valves, air domes, and pressure monitoring hardware. Crafted from forged alloy steel, wear-resistant cast iron, oil/abrasion-resistant elastomers, and corrosion-resistant metal alloys, all parts meet strict API 7K standards for drilling pump equipment, making them the trusted choice for structural repairs, routine maintenance, full pump overhauls, and emergency field fixes.

Functional Specifications

  • Heavy-Duty Structural Support: Reinforced rack and base assemblies withstand torsional loads up to 110,000 lbs, maintaining precise pump alignment under continuous high-vibration operation and 60Mpa pressure cycling.
  • Leak-Free Sealing Performance: Multi-size single/two-lip oil seals, O-rings, and packing rings prevent lubricant loss and fluid leaks, protecting internal rotating components and maintaining clean, compliant rig conditions.
  • Smooth Power Transmission: Precision-machined crankshaft and pinion assemblies ensure efficient torque transfer, minimizing energy loss and reducing premature wear on bearings and crosshead components.
  • Safety & Pressure Monitoring: JA-3 shearing safety valves, KB-75 air domes, and 60Mpa quake-proof pressure gauges provide critical overpressure protection and real-time performance tracking to prevent catastrophic pump failure.
  • Vibration-Resistant Fastening: High-tensile bolts, nuts, and spring washers maintain tight assembly integrity under harsh field conditions, eliminating vibration-induced loosening and structural misalignment.

Structural Characteristics

These CSF-1300 frame components feature a rugged, field-optimized modular design: welded reinforced rack assemblies for maximum structural rigidity, interchangeable crosshead and crankshaft components for quick replacement, precision-machined sealing interfaces for universal OEM fit, and standardized fasteners for simplified installation. The modular layout allows targeted replacement of worn individual parts instead of full frame overhauls, cutting material waste and repair labor time significantly.

Applicable Operating Conditions

These components are engineered to perform reliably in the most demanding drilling environments: onshore deep-well oil/gas exploration, offshore platform well servicing, directional drilling, geothermal drilling, and high-solid abrasive mud circulation operations. They tolerate extreme temperature fluctuations (-20°F to 220°F), acidic drilling fluids, continuous 60Mpa pressure cycling, heavy dust exposure, and high-vibration rig conditions, making them suitable for remote land rigs, offshore vessels, and commercial drilling installations worldwide.

Maintenance & Servicing Recommendations

To maximize component lifespan and preserve frame integrity, follow these industry-approved maintenance protocols: inspect all oil seals, O-rings, and packing rings every 300 operating hours for wear, cracking, or leakage, replacing damaged parts immediately; re-torque all bolts, nuts, and stud bolts to OEM-specified torque values every 450 hours to prevent vibration-induced loosening; inspect rack and base assemblies for cracks or misalignment quarterly; calibrate quake-proof pressure gauges semi-annually to ensure accurate readings; lubricate crankshaft and crosshead components with API-approved lubricant every 600 operating hours; and clean strainers, air vent covers, and copper mesh filters regularly to maintain unobstructed fluid and air flow.

Field Failure Repair Case Studies

Case 1: Worn Two-Lip Oil Seal Causing Crankshaft Lubricant Leak

A land drilling rig operating a CSF-1300 pump detected persistent lubricant leaks around the crankshaft assembly, traced to a degraded two-lip oil seal. Replacing the OEM-matched oil seal and re-sealing the assembly stopped leaks completely, preventing bearing dry-running and extending crankshaft service life.

Case 2: Loose M27 Frame Bolts Causing Structural Misalignment

An offshore well servicing crew reported abnormal pump vibration and reduced pumping efficiency, caused by loose M27 frame bolts that weakened structural stability. Re-torquing the bolts, replacing worn spring washers, and realigning the rack assembly restored smooth operation, eliminating vibration-related component wear.

Case 3: Faulty KB-75 Air Dome Airbag Leading to Pressure Instability

A remote drilling rig faced erratic pressure fluctuations on a CSF-1300 pump, due to a ruptured airbag in the KB-75 air dome. Installing a new OEM-grade airbag and seal ring restored consistent pressure stabilization, preventing hydraulic shock to the fluid end assembly and resuming normal drilling operations.
