Maintenance & Care Recommendations

To extend the service life of the parts and ensure the stable operation of the equipment, we recommend the following maintenance and care measures:

1. Daily Inspection

Check the connection status of hydraulic components, bolts, and nuts regularly (once a week), and tighten them in time if there is loosening; check the surface of filter elements and oil seals for damage, deformation, or leakage, and replace them in time if any abnormality is found.

2. Regular Replacement

According to the equipment operation time and working environment, replace the wearing parts regularly: (1) Filter elements (37540-02100, 23049373/29510910S) should be replaced every 2000 working hours; (2) Oil seals and O-rings (530301011250070007, 5300200106) should be replaced every 3000 working hours; (3) Thrust bearings and bushings should be inspected every 5000 working hours, and replaced if the wear exceeds 0.1mm.

3. Storage Requirements

Unused parts should be stored in a dry, ventilated, and dust-free warehouse, avoiding direct sunlight and contact with corrosive substances; hydraulic components and electrical parts should be stored in a moisture-proof environment (relative humidity ≤60%) to prevent rust and damage to internal components.

4. Installation Notes

When installing the parts, ensure that the installation position is correct and the connection is tight, and avoid forced installation to prevent damage to the parts; before installation, clean the installation interface to remove impurities and oil stains, ensuring the tightness and compatibility of the parts.

On-site Fault Maintenance Cases

The following are 3 real on-site fault maintenance cases, which can help you quickly judge and solve problems by using our parts:

Case 1: Hydraulic System Pressure Instability of ZJ30DB Drilling Rig

Fault Phenomenon: The hydraulic system of the ZJ30DB drilling rig has unstable pressure during operation, and the shift is not smooth, which affects the drilling efficiency. Fault Cause: The original high-pressure control valve (DLF5/16-00) is worn, resulting in internal leakage and pressure fluctuation. Solution: Replace the original valve with our high-pressure control valve DLF5/16-00. After replacement, the system pressure is stable at 30MPa, the pressure fluctuation rate is less than 1%, and the shift operation is smooth. The equipment returns to normal operation, and the maintenance cost is reduced by 40% compared with replacing the original parts.

Case 2: Filter Blockage of Mitsubishi Machinery

Fault Phenomenon: The hydraulic pump of Mitsubishi machinery has abnormal noise, and the oil temperature rises rapidly, which leads to frequent shutdown of the equipment. Fault Cause: The original filter element (37540-02100) is blocked by impurities, resulting in poor oil circulation and increased load on the hydraulic pump. Solution: Replace the filter element with our Mitsubishi filter element 37540-02100. After replacement, the oil circulation is smooth, the noise of the hydraulic pump disappears, the oil temperature returns to normal (35-45℃), and the service life of the hydraulic pump is extended by 30%.

Case 3: Electrical Signal Distortion of Rotary Encoder

Fault Phenomenon: The rotary encoder of the industrial production line (model 380504050400000000) has signal distortion, resulting in inaccurate equipment positioning and product quality defects. Fault Cause: The internal circuit of the original encoder is aging, and the signal transmission is unstable. Solution: Replace the encoder with our rotary encoder 380504050400000000. After replacement, the signal transmission accuracy reaches 99.99%, the equipment positioning is accurate, and the product qualification rate is increased by 25%.
