Hydraulic pipe joint of excavator leaks oil

Oil leakage often occurs at the hydraulic pipe joints of excavators, and the reasons are as follows:

1. Working principle: Here I will explain in layman’s terms that due to the frequent impact of the hydraulic oil pump during the operation of the excavator breaker hammer, sufficient power is provided to the digging bucket and the drill rod of the breaker hammer to carry out production work.

2. Reasons for oil leakage in hydraulic pipe joints of excavators: Strong vibrations and hydraulic oil impacts during production can cause loose threads at the hydraulic pipe joints of excavators, leading to oil leakage. Therefore, it is necessary to regularly check the tightness of the pipe joints. Strong vibrations and hydraulic oil impacts during work may cause loosening of oil pipe connections, leading to oil leakage.
3. Reasons for oil leakage in hydraulic pipe joints of excavators: If the material of the excavator hydraulic pipe joint does not meet the standard due to strong vibration during production, vibration marks will appear at the 60 degree or 74 degree connection seal, causing oil leakage. At this time, the restraining effect is no longer effective because the seal has been damaged. If the interface material is not suitable, it may cause rusting of the internal structure, thereby affecting the fluidity of the internal liquid or causing water leakage at the interface, resulting in oil leakage at the interface
4. Reasons for oil leakage in hydraulic pipe joints of excavators: The sealing ring and oil seal may age or be damaged during operation due to the influence of working time and environment, resulting in oil leakage. In this case, it is necessary to replace them with new ones, otherwise it will affect the work during operation or repair tasks. If used interchangeably, there are safety hazards because the temperature of hydraulic oil will be very hot during operation. Under the influence of work environment and time, sealing rings and oil seals may age or be damaged, leading to oil leakage.
5. The occurrence of excavator oil leakage faults may be related to the excavator operator’s daily operation and use of the excavator. Therefore, it is necessary to avoid the occurrence of excavator oil leakage faults. Excavator operators should use the excavator according to the prescribed requirements during daily operation and use, and do a good job in daily maintenance of the excavator to reduce the occurrence of excavator oil leakage faults.
