Maintenance & Care Suggestions

To extend the service life of the products, reduce equipment failure rate, and ensure the stable operation of the entire equipment system, we provide the following professional maintenance and care suggestions, which are practical and easy to operate, and can help users reduce maintenance costs and improve equipment utilization:

1. Regular Inspection: For hydraulic valves, sealing parts, and belts, conduct a comprehensive inspection every 100 working hours, check for wear, cracks, deformation, and leakage, and replace them in time if any abnormality is found; for PDC drill bits and pump impellers, check for wear and damage every 200 working hours.

2. Cleaning & Replacement: Clean the surface of filters (line filter ZUI-E25×10BD-P, filter element 6I-2501) every 50 working hours, and replace the filter element every 500 working hours; clean the impeller and throatbush of the pump every 800 working hours to remove sediment and impurities, ensuring smooth flow.

3. Lubrication Maintenance: Apply lubricating oil (No. 32 anti-wear hydraulic oil) to transmission parts (turbo shaft, crank shaft) every 200 working hours, and apply grease to bearings (SB68J0024, DW40C5003BZ000009) every 300 working hours to reduce friction and wear, extending the service life of the parts.

4. Storage Requirements: Unused spare parts should be stored in a dry, ventilated, and clean warehouse, avoiding direct sunlight, rain, and contact with corrosive substances; the storage temperature should be controlled between -10℃ and 40℃, and the relative humidity should not exceed 75%; for sealing parts and O-rings, store them in sealed packaging to avoid aging.

5. Installation & Fault Handling: When installing the parts, ensure that the connection is tight, and the torque meets the standard (refer to the original equipment manual); do not use damaged or unqualified parts. If the parts fail during use, stop the equipment immediately, check the cause of the fault according to the maintenance manual, and do not force the equipment to operate to avoid secondary damage to the equipment.

On-Site Fault Maintenance Cases

We have accumulated rich on-site maintenance experience in long-term cooperation with oilfield, boiler, and water treatment enterprises. The following are 3 real on-site fault maintenance cases, which can provide practical reference for users to solve similar technical problems and ensure the rapid recovery of equipment operation:

Case 1: ZJ50 Mud Pump Belt Breakage

Fault Phenomenon: During the operation of the ZJ50 mud pump, the pump belt (8V*J4*10160) suddenly broke, resulting in the mud pump stopping working and affecting the drilling progress.

Fault Cause: The belt had been used for more than 2500 working hours, exceeding the service life, and the surface was severely worn, leading to breakage under high load.

Maintenance Solution: Replace the mud pump belt with our 8V*J4*10160 spare part, adjust the belt tension according to the standard (20-30mm deflection under 100N force), and test the pump operation. After replacement, the mud pump operates normally, and the belt runs stably, ensuring the drilling progress is not affected.

Case 2: DQ70 Drilling Rig Hydraulic System Leakage

Fault Phenomenon: The DQ70 drilling rig’s hydraulic system had serious oil leakage at the back clamp, resulting in insufficient hydraulic pressure and unstable operation of the clamp.

Fault Cause: The back clamp seal (DQ70 260×230×14.5 2.4.99.01.005) was aged and damaged, leading to oil leakage.

Maintenance Solution: Replace the back clamp seal with our DQ70 260×230×14.5 2.4.99.01.005 spare part, clean the sealing surface, and apply lubricating oil. After replacement, there is no oil leakage, the hydraulic system pressure is stable at 28MPa, and the back clamp operates normally.

Case 3: DZS1-0.7-QY Boiler Water Level Control Failure

Fault Phenomenon: The DZS1-0.7-QY industrial boiler’s water level control panel (AP-1) failed, the water level display was inaccurate, and the boiler could not automatically adjust the water supply, posing a safety hazard.

Fault Cause: The circuit board (23045141) of the water level control panel was damaged, leading to signal transmission failure.

Maintenance Solution: Replace the circuit board with our 23045141 spare part, calibrate the water level sensor, and test the control function. After replacement, the water level display accuracy is ±1mm, the boiler can automatically adjust the water supply, and the safety hazard is eliminated.
