Every finished part undergoes pressure testing, dimensional calibration and material fatigue inspection to form unified procurement standards and on-site technical troubleshooting guidelines.

2. Product Introduction & Functional Description

2.1 Core Product Composition

This integrated spare parts system covers six core functional modules: Hydraulic power components including L10VSO100DFLR piston pumps, HJC and KCB83.3 oil pumps, Rexroth control valves and full-series hose assemblies; disc brake system parts consisting of PS80 composite brake units, BG-00C emergency cylinders, KQ-21 working brake heads, BQ-22 emergency brake heads and friction disc cores; transmission and bearing assemblies with multi-model SKF bearings, standard domestic bearings, cardan shafts, clutch covers and toothed clutches; sealing and adjusting accessories including multi-spec O-rings, oil seals, control shims, retaining rings and spring washers; pneumatic and filtering components covering air filters, hydraulic filters, check valves and three-way valve assemblies; auxiliary structural parts such as brake brackets, rope stops, air springs, pressure gauges and position limiters.

2.2 Practical Working Functions

Hydraulic pump and valve assemblies provide stable pressure and flow output for the entire rig hydraulic system, ensuring accurate execution of braking, clutch switching and drawwork lifting actions. PS80 disc brake systems integrate normally open and normally closed structures to achieve reliable working braking and emergency locking, preventing drilling tool runaway accidents. High-precision bearings and cardan shafts stabilize power transmission operation and eliminate rotational jitter. Professional sealing accessories block hydraulic oil leakage and external dust intrusion. Filter elements continuously purify hydraulic oil circuits to reduce precision component abrasion. Control shims and limit parts calibrate assembly clearance to maintain long-term system operating accuracy and stability.

3. Structural Features & Applicable Working Conditions

3.1 Unique Structural Advantages

PS80 disc brakes adopt a composite multi-pad structure with uniform force distribution, effectively solving local stress concentration and rapid friction disc wear defects. L10VSO variable piston pumps feature adaptive pressure regulation structure to adapt to variable load changes. SKF heavy-duty bearings adopt optimized internal clearance design with strong anti-vibration and anti-fatigue capabilities. All sealing parts use composite rubber materials with high temperature resistance and low aging rate. Modular valve body and hose assembly structures support quick disassembly and on-site replacement, greatly improving maintenance efficiency for field teams.

3.2 Adaptable Working Scenarios

This series of spare parts adapts to conventional onshore oil and gas exploitation, deep well high-pressure drilling and long-cycle uninterrupted operation of heavy-duty drilling rigs. Components stably work in ambient temperatures ranging from -40℃ to 85℃, resisting salt fog corrosion, high dust accumulation and continuous mechanical vibration. All parts support 24-hour cyclic operation of drawwork braking, hydraulic power transmission and pneumatic control systems under rated heavy load conditions.

4. Practical Field Maintenance Suggestions

Summarized from decades of front-line oilfield maintenance experience, standardized upkeep effectively reduces system failure rates. Replace hydraulic filter elements every 600 working hours to avoid oil circuit blockage and pump body wear. Inspect disc brake pad thickness and sealing ring status every 700 working hours to maintain stable braking performance. Check bearing lubrication and cardan shaft fastening status after each heavy-load drilling cycle. Calibrate pressure switch and position limiter data accuracy quarterly. Avoid mixed installation of non-standard gaskets and shims; conduct full-pressure holding testing after hydraulic component replacement to eliminate hidden leakage risks.
