3. Core Functional Description

3.1 Stable Braking & Control Function

Matched with JC32B series brake drums, DPZ70 disc brakes and JC28 series brake shafts and brake rims, the product achieves sensitive and stable braking control. It effectively solves the pain points of delayed braking response and insufficient braking torque of old equipment under frequent start-stop and heavy-load working conditions, ensuring safe and reliable equipment operation.

3.2 Efficient Power Transmission Function

Components including BHJ20QC400 drive shafts, 2LYQC850-9.4A right gearboxes, 324WCB ring gears and JXB260-31 keys form a complete power transmission system. It eliminates transmission jitter and power loss caused by part wear and poor meshing, maintaining continuous and efficient power output of mechanical equipment.

3.3 Filtration & Sealing Protection Function

C-M90X2 air filters and NJU-400×180F-C oil suction filters effectively block impurity particles in oil and gas circuits, solving the problem of internal pipeline blockage and component abrasion. Matching gaskets, plugs and shaft sleeves provide all-round sealing protection to avoid liquid leakage and dust invasion inside the equipment.

4. Structural Characteristics

All parts adopt modular integrated structural design with unified assembly benchmarks and precise size calibration. Custom JC28 and JX/BJX series components adopt integral forging and precision finishing technology, featuring high structural rigidity and strong deformation resistance. The optimized balance beam and Y-support structure balance equipment operating torque, while the limiting device and adjusted screw bar realize accurate stroke and position control. Standard fasteners and customized special parts achieve zero-gap matching, supporting quick disassembly, replacement and daily maintenance in field environments.

5. Applicable Working Conditions

This series of supporting parts is mainly applicable to heavy-load hoisting, braking and transmission equipment for oilfield exploration, well repair and engineering construction. It stably adapts to working environments with ambient temperatures ranging from -25℃ to 50℃, frequent start-stop circulation and continuous heavy-load operation. It can resist dust erosion and slight vibration impact in open-air field scenarios, and is compatible with all mechanical equipment equipped with JC28, JX and BJX series host supporting systems.

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

Based on years of field maintenance experience, air and oil suction filters need cleaning every 3 months and replacement every 10 months to prevent filter clogging from affecting equipment power. Braking system components such as brake rims and brake drums require a gap calibration every 6 months to avoid braking failure caused by wear. Transmission gears and bearings need regular lubrication supplementation to reduce friction loss. Standard bolts and washers under long-term vibration should be inspected for fatigue deformation regularly. Standardized maintenance can extend the overall service life of the equipment supporting system by 1800 working hours compared with irregular maintenance modes.
