2. Product Introduction

The complete product portfolio covers four core functional modules: drill motor power components, hydraulic braking systems, lubrication and heat dissipation assemblies and sealing & structural accessories. Core power units include left and right 118217 series drill motor assemblies, matched with toothed belt and pulley sets to ensure stable power transmission. Braking systems consist of 109528 caliper disc brake assemblies and 109555 brake rotors, cooperating with 114860-2 KShZ full repair kits to support complete brake system disassembly and performance recovery. Lubrication and heat dissipation parts feature 30122104 oil heat exchangers, 117603-1 lubrication Hacoc assemblies, flush pipe components and breather pipe sets to achieve circulating cooling and fluid purification. Supporting accessories cover multi-spec O-rings, PolyPak seals, oil seals, bearing insulators, bearing shields, safety relief valves and magnetic stoppers, forming full-process sealing, protection and fault prevention solutions for top drive hydraulic and power systems.

3. Functional Description

118217 series left and right drill motor assemblies provide stable high-torque power output for drilling operations, ensuring consistent rotational speed under variable formation load. Caliper disc brake assemblies achieve rapid braking and reliable positioning of drill motors, eliminating tool rotation displacement during tool joint connection and disconnection. KShZ complete repair kits replace worn internal components to restore original braking torque and mechanical coordination accuracy. Oil heat exchangers and circulating lubrication assemblies reduce hydraulic fluid operating temperature and maintain stable fluid viscosity, effectively avoiding component abrasion caused by dry friction. Multi-stage sealing parts block internal hydraulic leakage and external dust and moisture ingress, while safety valves and magnetic stoppers prevent system overpressure damage and metal particle contamination.

4. Structural Characteristics

All drill motor internal structures adopt precision gear grinding technology, maintaining stable torque output after 17200 continuous cyclic operations without power attenuation. Disc brake assemblies adopt dual-sided caliper clamping structure, achieving uniform stress and rapid response braking. KShZ repair kit accessories adopt unified dimensional tolerance calibration, realizing zero-tolerance assembly matching with original equipment structures. Heat exchanger internal flow channels adopt enhanced heat exchange design to improve thermal conversion efficiency under long-duration high-load operation. Bearing insulators and shields form double mechanical protection, reducing motor bearing wear and electrical interference risks in complex electromagnetic environments.

5. Applicable Working Conditions

This component suite is fully compatible with mainstream top drive drill motor and hydraulic brake systems, adapting to offshore salt spray humid platforms, onshore desert high-temperature deep well sites and seasonal temperature-alternating oilfield working environments. It stably operates in ambient temperatures ranging from -32℃ to 70℃, supporting 24-hour uninterrupted high-torque drilling and frequent braking cyclic operations. All components resist hydraulic oil corrosion, high-temperature aging and mechanical fatigue, meeting long-cycle high-intensity operational maintenance demands of oil and gas exploration projects.

6. On-Site Maintenance & Engineer Practical Suggestions

Professional field drilling engineers recommend inspecting disc brake pad wear status every 430 operating hours to replace severely worn parts timely and avoid insufficient braking torque. Clean heat exchanger and flush pipe pipeline passages quarterly to eliminate oil dirt accumulation and ensure unobstructed heat dissipation circulation. Check all sealing components and O-ring status during seasonal overhaul to prevent micro-leakage caused by aging and fatigue. Verify safety valve pressure relief sensitivity before high-load drilling operations to avoid system overpressure hazards. Lubricate pulley and bearing assemblies regularly to reduce transmission friction loss and extend component service life.
