ZJ30DB14 Bomco Drilling Rig Parts

Core Application & Target User Demand

All parts listed are exclusively compatible with the Bomco ZJ30DB14 drilling rig, a core equipment widely used in onshore oil and gas exploration, shale gas development, and geological drilling projects. Targeting drilling contractors, oilfield maintenance teams, and energy project operators, these parts address critical demands for reliable replacement components—covering transmission, sealing, hydraulic, electrical, and structural systems—to minimize unplanned downtime, ensure operational safety in harsh drilling environments, and comply with industry standards such as GB/T, JB, SY/T, and international specifications for bearing and fluid components.

Product Overview & Functional Description

This parts portfolio integrates multi-system components for the ZJ30DB14 rig, including precision bearings (SKF, NSK, ZWZ brands), sealing elements (O-rings, oil seals), hydraulic fittings (hoses, joints, valves), electrical components (explosion-proof contactors, sensors), structural fasteners (bolts, pins), and core functional parts (clutches, pumps). Each component is engineered to match the rig’s operating parameters: the transmission parts ensure stable power transfer for drawworks and rotary tables; sealing elements prevent fluid leakage in high-pressure hydraulic systems; electrical parts meet explosion-proof requirements for hazardous oilfield zones; and structural parts withstand heavy loads and vibration during drilling operations.

Structural Characteristics

1. High Compatibility: All parts adhere to the original design specifications of Bomco ZJ30DB14, ensuring direct interchangeability with OEM components without modification. 2. Durability-Oriented Design: Bearings use GCr15 and 42CrMo materials for wear and fatigue resistance; sealing parts adopt nitrile rubber and fluorine rubber to withstand high pressure and oil corrosion. 3. Explosion-Proof & Safety Compliance: Electrical components (e.g., contactors, solenoid valves) meet EX explosion-proof standards, suitable for Zone 1 and 2 hazardous areas. 4. Modular Configuration: Components are categorized by system, facilitating quick identification and on-site replacement, reducing maintenance time.

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 60℃), low temperature (-20℃), humidity, and sand dust. 2. High-Pressure & Vibration Scenarios: Hydraulic components withstand working pressures up to 25MPa; structural parts resist continuous vibration from drilling operations. 3. Hazardous Zones: Explosion-proof electrical parts comply with IECEx standards, ensuring safe operation in flammable gas environments. 4. Long-Term Continuous Operation: Components are tested for 8,000+ hours of continuous operation, matching the rig’s high-duty cycle requirements.

Maintenance & Care Recommendations

1. Regular Inspection Schedules: Check bearings (per GB/T299) every 500 operating hours for clearance and lubrication; inspect O-rings (GB1235) and oil seals monthly for cracks or deformation. 2.Lubrication Management: Use NLGI 2 extreme pressure lithium grease for bearings and hydraulic oil complying with ISO VG46; replace lubricants per the rig’s maintenance manual. 3. Sealing System Maintenance: Apply 609 sealant (per manufacturer specifications) when installing gaskets; replace combination washers (JB982) after 3 disassembly cycles. 4. Electrical Component Care: Clean explosion-proof connectors (330399 series) quarterly to remove dust; test contactors and relays annually for contact reliability. 5. Storage Precautions: Store parts in a dry, temperature-controlled warehouse (5-25℃); protect hydraulic fittings with caps to prevent contamination.

On-Site Fault Maintenance Cases

Case 1: Bearing Failure in Drawworks

A ZJ30DB14 rig in a Shaanxi oilfield experienced abnormal noise in the drawworks. Inspection revealed wear on the ZWZ 23240 bearing (200X360X128) due to insufficient lubrication and axial displacement exceeding 0.1mm. Replacing the bearing with a genuine ZWZ 23240CA/W33 (per HG4-692 standards) and realigning the shaft with a dial indicator resolved the issue, extending bearing service life by 60%.

Case 2: Hydraulic Leakage from Hose Joints

During drilling operations in a Sichuan shale gas field, the rig’s hydraulic system leaked from NPT3/4 joints. Root cause was damaged O-rings (30×3.1) and loose clamp connections. Replacing the O-rings (GB1235) and retightening joints with torque wrenches (per SY/T5595) stopped the leakage, avoiding hydraulic pressure loss and ensuring normal operation of the drilling fluid system.

Case 3: Electrical Contactor Malfunction

A 3TF3200-0XN2 AC contactor failed to engage, causing the rig’s rotary table to shut down. Testing showed worn contacts due to long-term arcing. Replacing the contactor with a genuine unit and cleaning the explosion-proof enclosure (per GBYL-Y2X20 standards) restored power transmission, preventing a 12-hour downtime.

Case 4: Air Compressor Seal Failure

The rig’s air compressor suffered pressure loss due to damaged双唇 oil seals (AH1001010416). The seals deteriorated from high-temperature oil aging. Replacing the seals and flushing the lubrication system with NLGI 2 grease resolved the issue, ensuring the air compressor maintained stable pressure for downhole tools.
