Honghua JC Series Drawworks Spare Parts

Core Application & Target User Demand

All spare parts listed are exclusively compatible with Sichuan Honghua Petroleum Equipment’s JC series drawworks, including JC-70D, JC50DB, JC50, JC40DB, JC90, JC70DB, JC40, JC90DB, JC70D, and JC40D models. These drawworks are core equipment for onshore oil and gas drilling, shale gas development, and geological exploration projects. Targeting drilling contractors, oilfield maintenance teams, and energy project operators, the parts address critical demands—covering bearings, clutches, seals, hydraulic components, electrical parts, and transmission chains—to minimize unplanned downtime, ensure operational safety in harsh drilling environments, and comply with national and international standards such as GB/T, HG, JB, and ISO specifications for petroleum equipment components.

Product Overview & Functional Description

This parts portfolio integrates full-system components for Honghua JC series drawworks, encompassing precision bearings (SKF and standard-compliant models), air/hydraulic clutches (LT series), sealing elements (oil seals, O-rings, combined washers), hydraulic valves (flow regulating, overflow, solenoid valves), gear pumps, pressure gauges, transmission chains (double-row, six-row, four-row), structural fasteners (bolts, nuts, pins), and brake system parts (disc brakes, brake pads, piston rods). Each component is engineered to match the drawworks’ operating parameters: bearings ensure stable power transmission for drum and input shafts; clutches control torque transfer with high responsiveness; sealing parts prevent fluid leakage in high-pressure systems; and transmission chains maintain reliable power transfer under heavy loads, supporting the drawworks’ core function of hoisting drill strings and casing.

Structural Characteristics

1. OEM Compatibility: All parts adhere to Honghua’s original design specifications and comply with relevant standards (GB/T288-94, HG4-692-67, GB3452.1-82), ensuring direct interchangeability with factory components without modification. 2. Wear-Resistant Design: Bearings adopt high-strength materials such as GCr15 and 42CrMo, with CC/W33/C3 configurations for enhanced load capacity and fatigue resistance; sealing elements use nitrile rubber and fluorine rubber to withstand high pressure, oil corrosion, and temperature fluctuations. 3. Systematic Integration: Components are categorized by functional systems (transmission, hydraulic, brake, sealing), facilitating quick on-site identification and replacement, reducing maintenance labor costs. 4. Explosion-Proof & Safety Compliance: Electrical components (explosion-proof solenoid valves, pressure gauges) meet EX explosion-proof standards, suitable for Zone 1 and 2 hazardous areas in oilfields.

Applicable Working Conditions

These parts are designed for the extreme operating conditions of onshore oil and gas drilling, including: 1. Harsh Climatic Environments: Resistant to high temperature (up to 65℃), low temperature (-25℃), humidity, sand dust, and corrosive media. 2. High-Load & Vibration Scenarios: Bearings and chains withstand continuous heavy loads (up to the drawworks’ rated hoisting capacity) and vibration from drilling operations; hydraulic components tolerate working pressures up to 25MPa. 3. Hazardous Zones: Explosion-proof parts comply with IECEx and ATEX standards, ensuring safe operation in flammable gas-rich environments. 4.Long-Term Continuous Operation: Components are tested for 10,000+ hours of continuous operation, matching the JC series drawworks’ high-duty cycle requirements in oilfield drilling.

Maintenance & Care Recommendations

1. Regular Inspection Schedules: Check bearings (per GB/T288-94) every 600 operating hours for clearance, lubrication, and wear; inspect oil seals (HG4-692-67) monthly for cracks, deformation, or oil leakage. 2. Lubrication Management: Use NLGI 2 extreme pressure lithium grease for bearings and transmission chains; hydraulic systems adopt ISO VG46 hydraulic oil; replace lubricants and filters (primary/secondary oil filters) per the drawworks’ maintenance manual. 3. Sealing System Maintenance: Replace O-rings (GB3452.1-82) and combined washers (JB982-77) after 3 disassembly cycles; apply 609 sealant to mating surfaces to enhance sealing performance. 4. Clutch & Brake Maintenance: Inspect friction pads of LT series clutches every 800 hours; adjust brake caliper clearance (per PS80 hydraulic disc brake specifications) to ensure braking responsiveness. 5. Storage Precautions: Store parts in a dry, temperature-controlled warehouse (5-25℃); protect hydraulic fittings and valves with dust caps to prevent contamination; avoid direct sunlight on rubber components to prevent aging.

On-Site Fault Maintenance Cases

Case 1: Bearing Failure in JC50DB Drawworks Drum Shaft

A JC50DB drawworks in a Xinjiang oilfield experienced abnormal vibration and overheating in the drum shaft. Inspection revealed damage to the 22240C bearing (Φ200×Φ360×98) due to insufficient lubrication and axial displacement exceeding 0.2mm. Replacing the bearing with a GB/T288-94 compliant unit, realigning the shaft with a dial indicator, and refilling with NLGI 2 grease resolved the issue, extending bearing service life by 70% and avoiding unplanned downtime.

Case 2: Hydraulic Leakage in JC-70D Brake System

During drilling operations in a Shandong oilfield, the JC-70D drawworks’ hydraulic disc brake system leaked. Root cause was worn O-rings (71×3.55) and damaged oil seals (PD250×290×18) complying with HG4-692-67. Replacing the seals with genuine parts, applying sealant to mating surfaces, and flushing the hydraulic system restored pressure stability, ensuring reliable braking performance.

Case 3: Clutch Malfunction in JC40DB Drawworks

A JC40DB drawworks’ LT500/250T clutch failed to engage, causing hoisting interruptions. Testing showed worn friction pads and a damaged bladder. Replacing the friction pads, bladder, and inspecting the air control valve (QF515) resolved the issue. Following maintenance protocols for clutch air pressure adjustment ensured smooth torque transfer, reducing downtime by 10 hours.

Case 4: Transmission Chain Breakage in JC70D Drawworks

A JC70D drawworks’ 24S-6 six-row chain (GB3638-83) broke during heavy hoisting. Root cause was insufficient lubrication and wear from sand dust contamination. Replacing the chain with a genuine GB3638-83 compliant unit, cleaning the chain drive mechanism, and establishing a weekly lubrication schedule (using extreme pressure grease) prevented recurrence, extending chain service life by 50%.
