Influence and reason of oil leakage in oil pipe of hydraulic pump

Causes of oil leakage in oil pipe of hydraulic pump

The reasons for oil leakage in oil pipe of hydraulic pump generally include the following:

1. Loose pipe joints: Due to long-term use, vibration, temperature rise and fall, etc., the fasteners of the pipe joints are easy to loosen, causing oil pipe leakage.

2. Pipeline aging: Due to long-term use, the oil pipe will age due to erosion by hydraulic oil and metal fatigue, resulting in cracks and damage in the oil pipe, resulting in oil pipe leakage.

3. Poor pipeline installation: If the installation is not standardized and there are grooves in connections, bends, etc., carelessness will occur, causing damage to the oil pipe and oil leakage.

The impact of oil leakage from hydraulic pump oil pipes on the hydraulic system

Oil leakage from the hydraulic pump oil pipe will have the following effects on the normal operation of the hydraulic system:

1. Pressure reduction: Because part of the flow output by the pump body is leaked after flowing out, the pressure cannot maintain the normal value.

2. Increased energy consumption: Due to oil leakage, the hydraulic pump needs to output more flow to maintain the original pressure. This will lead to increased energy consumption in the hydraulic system.

3. Oil pollution: Due to leakage in the oil pipe, the hydraulic oil enters the external environment of the system and is easily inhaled by the air with adsorbed impurities, resulting in an increase in the impurity content of the oil and a reduction in the life of the system.

Preventive measures

In order to avoid oil leakage from the hydraulic pump oil pipe, the following preventive measures can be taken:

1. Pay attention to the quality of pipeline installation: During the installation process, attention should be paid to defects in seals, fasteners and other accessories, and the opening size and processing quality of the oil passage should be strictly controlled.

2. Regular inspections: Conduct regular inspections of the hydraulic system to promptly detect problems such as aging, wear, and leaks in the pipelines and repair them.

3. Use high-quality products: Use high-quality, corrosion-resistant hydraulic oil pipes and fasteners to reduce oil leakage rates. Choose a reputable supplier for high-quality hydraulic components and accessories.
 

Conclusion

This article briefly introduces the impact and cause analysis of oil leakage in hydraulic pump oil pipes. The hydraulic system is a precision project, and the quality requirements for its pipelines are also very high. Ensuring that the oil pipe does not leak oil is very important to reduce hydraulic system failures and extend service life.
