Core Purpose & Target User Needs

The core purpose of our products is to ensure the safety, reliability, and continuity of critical drilling operations—from ZJ-20 drilling rig pneumatic/hydraulic systems and JC21D drawworks to ZD-500 BOP handling systems. These components work together to keep drilling equipment running smoothly: pneumatic/hydraulic components (810612-00-0015 valve, ZJ30-10-07-00 control unit) regulate fluid and air flow for precise system control; sensors (82234 2088G4, SA1111E-S5-K2) monitor key parameters (pressure, temperature, oil level) to prevent overheating and system damage; bearings (TIMKEN 24122EJW33C3, NU236EMA) reduce friction in rotating components; filters (810504 series) keep hydraulic/pneumatic systems clean; and cables (4061112, TDQ series) ensure reliable electrical signal and power transmission—all critical for avoiding catastrophic equipment failures, ensuring operator safety, and maximizing drilling productivity.

We target four key user segments, each with distinct, specialized needs:

• ZJ-20 Drilling Rig Operators: Manage ZJ-20 drilling rigs, needing reliable spare parts (810612-00-0015 air control valve, ZJ30-10-07-00 hydraulic control unit, 870902-01-0130 check valve, 810504 series oil filters) to maintain pneumatic/hydraulic system performance and prevent rig downtime.

• JC21D Drawwork & Winch Maintenance Teams: Maintain JC21D drawworks and winches, requiring components like JC21A-03-01-00 brake tape, JC21D-03-01-00 bushing, 600320-05-3000 copper screw, and TPQ 124-02 spring to ensure smooth operation and safe load handling.

• Drilling Equipment Electrical Technicians: Install and maintain electrical systems of drilling equipment, needing electrical components (MT-MN 033682 circuit breaker delay unit, DRM570024LT relay, 4NIC-CD240 power supply unit, TDQ series cables) to ensure reliable power supply and signal transmission.

• BOP Handling System Operators: Manage ZD-500 BOP handling systems, requiring SLING ASSY LIFT DZ5001-10.00A and other specialized parts to ensure safe and efficient BOP movement during drilling operations.

Key pain points we solve: ZJ-20 rig shutdowns due to faulty air control valves (810612-00-0015) or hydraulic control units (ZJ30-10-07-00); JC21D drawwork failures from worn brake tapes (JC21A-03-01-00) or bushings (JC21D-03-01-00); hydraulic system damage from contaminated oil (lack of 810504 series filters); electrical malfunctions from faulty relays (DRM570024LT) or power supply units (4NIC-CD240); and BOP handling accidents from low-quality slings (DZ5001-10.00A)—all of which result in costly downtime, safety risks, and increased maintenance expenses.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases and practical solutions, helping you quickly resolve common technical issues, reduce downtime, and maximize the performance of our components:

Case 1: ZJ-20 Pneumatic System Failure (810612-00-0015 Air Control Valve)

Fault Phenomenon: A ZJ-20 drilling rig’s pneumatic system failed to operate, with the air control valve 810612-00-0015 not responding to control signals, preventing the operation of pneumatic actuators. Solution: The valve was inspected and found to be clogged with mud and debris, causing internal jamming. The valve was disassembled, cleaned, and reinstalled, and the pneumatic system was tested to ensure smooth operation.Cause Analysis: Drilling mud entered the valve during operation, causing internal components to jam. Suggestion: Clean the air control valve weekly and install a pre-filter to prevent debris from entering the valve.

Case 2: JC21D Drawwork Brake Failure (JC21A-03-01-00 Brake Tape)

Fault Phenomenon: A JC21D drawwork’s brake failed to hold the load, with the brake tape JC21A-03-01-00 showing excessive wear. Solution: The worn brake tape was replaced with a new JC21A-03-01-00 brake tape, and the brake tension was adjusted to ensure proper friction. The drawwork was tested, and the brake performed reliably. Cause Analysis: Prolonged high-load operation caused excessive wear of the brake tape’s friction material. Suggestion: Inspect the brake tape weekly for wear and replace it every 8,000 working cycles or when the thickness is less than 5mm.

Case 3: ZJ-20 Hydraulic System Contamination (810504-00-0370 Oil Filter)

Fault Phenomenon: A ZJ-20 hydraulic system experienced abnormal noise and reduced performance, with the oil filter 810504-00-0370 showing a high pressure differential. Solution: The clogged oil filter was replaced with a new 810504-00-0370 filter, and the hydraulic fluid was drained, filtered, and refilled. The hydraulic system resumed normal operation. Cause Analysis: Contaminants (dust, metal particles) in the hydraulic fluid clogged the filter, restricting fluid flow. Suggestion: Replace the oil filter every 2,000 operating hours and check the hydraulic fluid for contamination monthly.
