Maintenance & Care Suggestions

To extend the service life of the products and ensure the stable operation of the equipment, we provide the following professional maintenance and care suggestions, which can reduce the failure rate of parts by 40% and extend the service life by 30%:

1. Regular Inspection: For easily worn parts (such as seals, friction plates, and filter elements), inspect them every 500 working hours, and replace them in time if there is wear, deformation, or damage; for bearings, check the lubrication status every 300 working hours, and add lubricating oil in time.

2. Proper Storage: When the parts are not in use, store them in a dry, ventilated, and clean warehouse, avoiding direct sunlight, rain, and corrosion by chemical substances; for seals and O-rings, store them in a low-temperature environment (0℃ to 10℃) to prevent aging.

3. Correct Installation: When installing the parts, strictly follow the original equipment installation manual, ensure that the installation is in place, and avoid loose connections or incorrect installation, which may lead to part damage or equipment failure; for hydraulic parts, check for oil leakage after installation, and deal with it in time if there is leakage.

4. Lubrication Maintenance: For rotating parts (such as bearings, gears, and winch drums), regularly add appropriate lubricating oil (according to the equipment manual), and replace the lubricating oil every 2000 working hours to ensure good lubrication and reduce wear.

5. Fault Handling: If the parts fail during operation, stop the equipment immediately, check the cause of the failure, and replace the damaged parts with genuine products; do not use inferior replacement parts to avoid further damage to the equipment.

On-Site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, which can provide reference for users to solve similar technical problems and reflect the reliability and compatibility of our products:

Case 1: Oil Filter Blockage of ZJ45 Drilling Rig

Fault Phenomenon: A ZJ45 drilling rig had a sharp drop in lubricating oil pressure during operation, and the equipment alarmed. After inspection, it was found that the original oil filter was blocked by impurities, resulting in poor oil circulation, and the filter element was severely worn.

Maintenance Solution: Replace the original filter with our oil filter ZJ45 Lx2S-160×1000L, clean the lubricating oil pipeline, and add new lubricating oil. The filter element of our product has a multi-layer filtration structure, which can effectively filter impurities and has a larger dirt-holding capacity.

Maintenance Effect: After replacement, the lubricating oil pressure of the drilling rig returned to normal (0.8-1.2MPa), and the equipment operated stably. The filter element was inspected after 1000 working hours, and there was no obvious blockage, which effectively extended the maintenance cycle.

Case 2: Brake Failure of ZJ50L Winch

Fault Phenomenon: A ZJ50L drilling rig winch had a brake failure during hoisting operation, and the brake could not effectively lock the winch drum, which posed a safety hazard. After inspection, it was found that the closed caliper bearing BQ-34 of the brake device was worn, and the brake pad was damaged.

Maintenance Solution: Replace the brake device ZJ50L closed caliper bearing BQ-34 and brake pad with our products, adjust the brake clearance, and test the brake performance.

Maintenance Effect: After replacement, the winch brake torque reached 1200N·m, which met the safety operation requirements. The brake worked normally during subsequent hoisting operations, and there was no failure after 800 working hours, ensuring the safety of the operation.

Case 3: Boiler Water Level Gauge Malfunction

Fault Phenomenon: A factory's WNS2-1.25-Y boiler had a water level gauge malfunction, the water level display was inaccurate, and the alarm function failed, which could easily lead to boiler dry burning.

Maintenance Solution: Replace the original water level gauge with our sensor type water level gauge C1.6-HB350, calibrate the sensor, and test the alarm function.

Maintenance Effect: After replacement, the water level measurement accuracy reached ±0.5mm, the real-time display was accurate, and the over-high and over-low water level alarms worked normally. The boiler operated stably for 6 months without any water level-related faults.
