Maintenance & Care Suggestions

Proper maintenance can effectively extend the service life of products, reduce equipment failure rates, and ensure the stable operation of oilfield equipment. The following are targeted maintenance suggestions for different product categories:

Valves & Valve Components

• Regularly check valves for leakage, corrosion, and blockage; it is recommended to inspect every 400 working hours. Clean the valve core and valve seat in time, and replace worn seals (such as OO-ring 9S4191) immediately.

• Lubricate the valve stem and moving parts every 200 working hours with high-temperature resistant lubricating grease (NLGI Grade 2) to ensure smooth operation.

• For electromagnetic valves (such as MFH-3-1/8-EX24DC), check the wiring and coil status every 300 working hours to avoid poor contact or coil burnout.

Drilling Tools & Mechanical Parts

• Inspect PDC drill bits for diamond wear and bit body damage after each use; grind the bit surface if necessary to maintain drilling efficiency. Store drill bits in a protective case to avoid collision.

• Regularly check sprockets, bearings, and drive shafts for wear and deformation; replace them in time if the wear exceeds 0.08mm. Add lubricating grease to rotating parts every 250 working hours.

• Clean the Righting body DQ70BS T7540205071 365×155 every 500 working hours to remove mud and impurities, ensuring the verticality of the drilling rig.

Hydraulic & Brake Components

• Regularly check hydraulic hoses (such as A8I-5500) for cracks, bulges, and oil leakage; replace them immediately if any damage is found. The service life of hydraulic hoses should not exceed 24 months.

• Replace hydraulic oil every 1200 working hours and clean the hydraulic filter element every 350 working hours to ensure the cleanliness of the hydraulic system (NAS 7 class).

• Inspect brake discs and brake calipers every 400 working hours; grind the brake disc surface if the wear exceeds 0.1mm, and replace worn brake pads in time.

Electrical & Filter Components

• Clean air filters and oil water separators regularly; replace the air filter element every 300 working hours and the oil water separator filter element every 500 working hours.

• Check starters, relays, and pressure controllers every 600 working hours; test their performance and replace damaged components (such as starter spring 6885166) in time.

• Store electrical components in a dry, dust-free environment, avoiding moisture and corrosion. Clean the surface of explosion-proof components regularly to ensure explosion-proof performance.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, providing practical reference for users to quickly solve similar problems, reduce downtime, and improve operation efficiency:

Case 1: ZJ50 Drilling Rig Hydraulic System Pressure Instability

Fault Phenomenon: The hydraulic system of the ZJ50 drilling rig had unstable pressure, with frequent pressure fluctuations, leading to slow movement of the hydraulic cylinder and affecting drilling efficiency.

Inspection & Analysis: After inspection, it was found that the Three-position five-way reversing valve ZJ50 VL-5/3E-D3-C had internal leakage, and the valve core was worn, resulting in unstable oil flow. The original valve had a short service life and poor wear resistance, which failed after only 800 working hours.

Maintenance Solution: Replace the original valve with our ZJ50 VL-5/3E-D3-C three-position five-way reversing valve. The new valve has a leakage rate of ≤0.1ml/min and a service life of more than 2000 working hours. After installation and debugging, the hydraulic system pressure was stable, the hydraulic cylinder operation was smooth, and the drilling efficiency was restored.

Case 2: Detroit Engine Fuel Supply Failure

Fault Phenomenon: The Detroit engine on the drilling rig had insufficient fuel supply, leading to unstable engine operation and frequent stalling, affecting the normal progress of drilling operations.

Inspection & Analysis: After inspection, it was found that the detroit oil water separator 23533816 was blocked by water and impurities, resulting in insufficient fuel supply. The original separator had a low separation efficiency, and the filter element was blocked after only 250 working hours.

Maintenance Solution: Replace the oil water separator with our detroit oil water separator 23533816. The new separator has a separation efficiency of ≥99.5% and a dirt-holding capacity of 60g. After replacement, the engine fuel supply was normal, the operation was stable, and no stalling occurred during 1000 hours of continuous operation.

Case 3: ZJ40DB Drilling Rig Turntable Abnormal Noise

Fault Phenomenon: The ZJ40DB drilling rig turntable made abnormal noise during operation, and the rotation speed was unstable, which could not meet the drilling requirements.

Inspection & Analysis: After disassembly, it was found that the pin ZJ40DB BK-4-6C was worn and deformed, and the Turntable ZP275 double row sprocket AG27500130 had tooth wear, resulting in unstable power transmission and abnormal noise.

Maintenance Solution: Replace the pin with our ZJ40DB BK-4-6C pin and the sprocket with our ZP275 double row sprocket AG27500130. After installation, the turntable operated stably, the abnormal noise disappeared, and the rotation speed returned to the normal range, ensuring the smooth progress of drilling operations.
