2. Product Introduction

The product portfolio covers full-range core supporting parts for drilling equipment, including XJ40C-09A series brake plates, swing arms, shaft sleeves and positioning pins, JC28 series transition flanges, chain rollers, adjusting gaskets and bearing covers. It is equipped with TPQ330 and ATD330H friction clutch assemblies, 22236C heavy-duty bearings, multi-specification standard bolts, nuts and cotter pins, as well as PD190X225X18 oil seal accessories and pneumatic hydraulic crane components. Every accessory adopts precision machining and high-strength forging technology, featuring high assembly accuracy and structural durability, fully compatible with XJ40C drilling rigs and supporting JC28/JC32B host systems to meet full-cycle equipment overhaul and daily maintenance needs.

3. Core Functional Description

3.1 High-stability Braking Control

XJ40C series cast brake plates and JC28 brake drums cooperate with ATD330H and TPQ330 friction clutches to form a complete braking and power separation system. This structure effectively solves the pain points of delayed braking response and friction attenuation caused by long-term high-frequency braking, maintaining stable braking torque output for drilling equipment under variable load conditions.

3.2 Efficient Power Transmission Operation

Custom keys, chain rollers, shaft sleeves and 22236C heavy-duty bearings form a reliable power transmission assembly. It eliminates power loss and mechanical jitter caused by part wear and assembly gaps, ensuring continuous and stable power transmission of drilling rig transmission structures in long-cycle operation.

3.3 Sealing & Pipeline Connection Protection

Multi-specification oil seals, transition flanges and straight pipe joints achieve tight sealing and stable connection of hydraulic and pneumatic pipelines. It avoids medium leakage and pipeline pressure fluctuation in field high-vibration environments, ensuring normal operation of pneumatic and hydraulic control systems of drilling equipment.

4. Structural Characteristics

All components adopt modular assembly design with unified industrial assembly tolerance benchmarks and excellent interchangeability for rapid on-site disassembly and replacement. XJ40C and JC28 series core structural parts adopt high-strength alloy forging process, with strong wear resistance and deformation resistance. The matched adjusting gaskets and positioning pins realize accurate equipment calibration, while standardized fasteners and sealing parts resist structural loosening and medium erosion. The optimized chain roller and bearing cover structure reduces mechanical friction and operational noise, adapting to harsh continuous working environments.

5. Applicable Working Conditions

This series of accessories is suitable for onshore oilfield drilling, well repair and heavy-load hoisting working scenarios. It stably adapts to open-air working environments with ambient temperatures ranging from -20℃ to 60℃, high dust concentration and frequent mechanical vibration. It fully matches the full-load operation parameters of XJ40C drilling rigs and JC28/JC32B supporting equipment, and can maintain stable mechanical performance under long-term intermittent heavy-load and high-frequency start-stop cyclic operation.

6. On-site Maintenance Suggestions (Engineer Practical Experience)

Based on long-term oilfield equipment maintenance experience, friction clutch components and brake plates need inspection every 4 months and integral replacement every 10 months to avoid friction attenuation failure. Bearings and transmission keys require regular lubrication supplementation to reduce friction loss. Pipeline sealing parts should be checked for aging and deformation regularly. Using mismatched fasteners and gaskets is forbidden, which will cause equipment operation deviation and part fatigue damage. Standardized maintenance can increase the overall stable working duration of supporting equipment by 2000 working hours compared with irregular maintenance modes.
