Exclusive bench test data confirms the matched parts maintain stable rated working pressure and rotational precision for 1200 consecutive operating hours under standard drilling load conditions.

2. Product Introduction

The product lineup includes drawworks braking and control components, reducer transmission gears, swivel sealing and bearing accessories, mud pump core spare parts, crownblock sheave assemblies and drilling tong slip inserts. Every component adopts industrial-grade raw materials and precision machining processes, covering all vulnerable and consumable parts of conventional medium-duty drilling rig supporting equipment. Core components such as WCB224 dynamic and static friction discs, SL 135 series sealing packs and TC158 crownblock bearings undergo strict pressure resistance, wear resistance and fatigue resistance tests, achieving full dimensional and performance compatibility with matched drilling equipment. It provides standardized, one-stop spare part supply solutions for daily operation and maintenance of oilfield drilling equipment.

3. Core Functional Description

Each spare part undertakes independent key functions to ensure coordinated and stable operation of drilling systems. The SDLT-00 dual guide valve controls the hydraulic logic of JC21D drawworks drum, solving unsmooth clutch switching faults; TPQ series friction plates and 710750-00-0080 brake blocks provide stable friction braking force for drawworks operation; ZJ-20 reducer gears with 21 and 35 teeth stabilize torque transmission and reduce transmission loss; SL 160 swivel seals and bearings isolate mud erosion and reduce rotational friction; F-800 mud pump piston assembly and dual-dial pressure gauges guarantee stable pumping pressure and real-time pressure monitoring; TC158 crownblock sheaves and bearings ensure smooth wire rope operation; tong dies and rotary slips provide stable clamping force for pipe handling operations.

4. Structural Characteristics

All drilling spare parts adopt working-condition optimized structural design for oilfield harsh environments. Friction plates adopt high-density alloy friction coating structure to enhance wear resistance and high-temperature resistance; chevron packing and cup seals adopt multi-lip composite structure to improve sealing performance under high mud pressure; reducer gears adopt carburizing and quenching integral molding structure to extend fatigue life; swivel and crownblock bearings adopt precision raceway polishing structure to reduce rotational resistance; slip inserts adopt tooth-shaped reinforced structure to improve pipe clamping stability and anti-slip performance.

5. Applicable Working Conditions

This series of spare parts is widely applicable to conventional onshore oil and gas drilling operations, water well drilling and geological exploration drilling scenarios. It stably adapts to harsh working environments including high mud erosion, continuous high-load operation, field dust pollution and temperature alternating changes. Field verification proves the parts can operate stably in the temperature range of -25℃ to 75℃, fully matching the long-cycle continuous operation demand of medium-duty drilling rigs in domestic and international conventional oilfields.

6. Professional Maintenance Suggestions (Engineer Practical Guide)

Based on long-term oilfield onsite maintenance experience, targeted maintenance can effectively extend equipment service life. Replace drawworks friction plates and brake blocks every 900 working hours to avoid insufficient braking force; inspect swivel sealing assemblies and bearings every 600 working hours to prevent mud leakage and shaft jitter; calibrate mud pump piston assembly and pressure gauge accuracy every 800 working hours; check crownblock sheave and bearing wear status every 1000 working hours; replace slip inserts regularly according to pipe clamping frequency to prevent pipe slipping accidents. Avoid overloading the drilling tool clamping system during daily operation to reduce abnormal wear of tong dies.

7. On-Site Drilling Fault Maintenance Cases

Case 1: Daqing Oilfield, JC21D Drawworks, Rated Drilling Load 450kN

The drawworks had slow braking response and unstable clutch engagement during drilling operation. Fault cause: severe wear of TPQ324-00 friction plate and aging of SDLT-00 dual guide valve. After replacing matching parts, the drawworks braking response time recovers to standard 0.2s, and clutch switching is smooth without jitter for 1200 consecutive working hours. Customer feedback: drawworks operation stability is fully restored, no intermittent faults occur.

Case 2: Tarim Oilfield, SL 160 Swivel, Continuous Mud Flushing Operation

Swivel shaft end mud leakage and rotational jitter occurred during deep drilling. Fault cause: failure of SL 135-06 chevron packing and fatigue wear of 32936 bearing. After replacing sealing and bearing components, zero mud leakage is realized, and swivel rotational runout is controlled within 0.1mm. Customer feedback: swivel operating performance meets factory standards, reducing field maintenance frequency.

Case 3: Shengli Oilfield, F-800 Mud Pump, Continuous Pumping Load

Mud pump pressure fluctuation exceeded standard range during circulating operation. Fault cause: aging BS0000060103 piston assembly and inaccurate pressure gauge data. After replacing core parts, pump pressure fluctuation is stabilized within 0.2MPa, meeting drilling circulating operation requirements. Customer feedback: mud pump operating efficiency is improved, and pressure failure rate is eliminated.

Case 4: Liaohe Oilfield, TC158 Crownblock, Long-Term Lifting Load

Crownblock sheave stuck and produced abnormal noise during pipe lifting. Fault cause: severe wear of Н760-03 sheave and 352936Е bearing. After replacing accessories, the sheave rotates flexibly without noise, and lifting operation is stable. Customer feedback: crownblock fault is completely resolved, ensuring safe drilling operation.
