2. Product Introduction & Functional Description

2.1 Core Product Composition

This integrated spare parts portfolio covers five core functional modules: Transmission bearing components including 32240, 22244CA/W33, 23048CA/W33, NU1048 and 6040 series high-load roller bearings; drawwork brake system parts consisting of PS-70-01-03A brake pads, FDR disc brakes, KG-80 normally open hydraulic cylinders, BG-80 normally closed hydraulic cylinders and emergency brake devices; hydraulic power assemblies with WBZ-40 and WBZ-63 oil pump assemblies, QGA series telescopic cylinders and QF528 mandril valves; pneumatic and pipeline systems including LT700/135 air tube clutches, 3/4″-M22×1.5 tee joints, multi-spec air and water pipe assemblies; auxiliary structural parts covering spacer sleeves, sprockets, adjusting washer sets, copper washers, O-rings, rope clamps and oil guiding ring assemblies.

2.2 Practical Working Functions

High-load roller bearings support stable rotary operation of JC70B drawwork main drum and transmission shafts, reducing rotary friction and avoiding shaft deflection caused by abrasion. Disc brake and hydraulic cylinder assemblies provide reliable normal braking and emergency locking protection to prevent drilling tool sliding risks. Oil pump and cylinder assemblies supply continuous stable hydraulic power for drawwork speed regulation and braking actions. Pneumatic clutch and pipeline assemblies ensure sensitive power switching and unobstructed gas circuit transmission. Sealing and washer accessories block hydraulic oil and gas leakage, while structural spacer and adjusting parts calibrate assembly clearance to maintain overall equipment operational stability.

3. Structural Features & Applicable Working Conditions

3.1 Unique Structural Advantages

All bearings adopt W33 oil groove design with enhanced lubrication performance, effectively solving bearing burnout and rapid abrasion defects under long-term heavy load. Brake pads and disc brakes adopt high-friction wear-resistant materials with stable friction coefficient, avoiding braking force attenuation after frequent use. Composite oil seals and felt rings feature dual dust-proof and leakage-proof performance, adapting to complex dusty oilfield environments. Sprocket and chain transmission parts adopt precision tooth profile machining to ensure tight meshing and low jitter. All standard fasteners strictly follow GB/T national standards to guarantee assembly accuracy and structural stability.

3.2 Adaptable Working Scenarios

This series of spare parts is specially developed for Gara Altyn JC70B onshore drilling rig drawwork systems, adapting to medium and deep well high-pressure drilling, long-cycle continuous heavy-load operation and frequent start-stop braking working conditions. Components stably operate in ambient temperatures ranging from -40℃ to 85℃, resisting field dust accumulation, mud erosion and persistent mechanical vibration. All parts support 24-hour uninterrupted cyclic operation of drawwork transmission, braking and hydraulic control systems.

4. Engineer Practical Maintenance Suggestions

Summarized from front-line oilfield overhaul experience, standardized maintenance effectively reduces system failure frequency: Replace bearing lubricating grease and inspect clearance every 650 working hours to avoid rotary jitter; renew brake pads and sealing assemblies every 700 working hours to maintain stable braking performance; clean oil pump filter elements and pipeline impurities regularly to prevent hydraulic blockage; calibrate hydraulic cylinder stroke and pneumatic clutch sensitivity after each heavy-load drilling cycle. Avoid mixed installation of non-standard bearings and sealing parts; conduct full hydraulic pressure holding testing after component replacement; never adjust brake system pressure parameters without professional calibration.
