At present, hydraulic systems have been widely used in machinery, textiles, mining, petroleum, mobile equipment and other industries, but sometimes three common problems occur during work: heat, vibration, and leakage. After more than ten years of research and industry practical experience, the three major problems have summed up corresponding solutions.
The heating of the hydraulic system is a manifestation of the increase in the temperature of the hydraulic oil. The reason is that the flow rate of each part of the hydraulic oil is different during the flow, which leads to a certain internal friction inside the liquid, and there is also friction between the liquid and the inner wall of the pipeline. , Causing the entire hydraulic temperature to rise.
Solution: Heat is an inherent feature of the hydraulic system and cannot be eradicated. It can only be reduced as much as possible. You can use high-quality hydraulic oil, high-quality pipelines and pipe joints, hydraulic valves, etc.
Strong vibration can cause errors in system control actions, and also cause friction damage to some of the more sophisticated instruments in the system.
Solution: Avoid sharp bends in the hydraulic pipeline, avoid frequent changes in the direction of the fluid flow, and if it is unavoidable, take timely shock absorption measures.
Leakage is generally divided into internal leakage and external leakage. Internal leakage refers to the leakage that occurs between the system and the external environment.
Solution: For leaks, better quality seals can be used to improve the processing accuracy of the equipment.
