Three major ills and solutions for the hydraulic system of film forming machines

1, fever

Because the force transmission medium (hydraulic oil) of the film forming machine has different flow rates in various parts during the movement, there is a certain internal friction inside the liquid, and there is also friction between the liquid and the inner wall of the pipeline, which causes the hydraulic oil. The reason for the increase in temperature. An increase in temperature will result in an increase in internal and external leakage and a decrease in mechanical efficiency. Together, because of the higher temperature, the hydraulic oil will swell and cause an increase in compressibility, so that the manipulation can not be transmitted well. Solution: Heat is an inherent feature of the hydraulic system of a film forming machine. It cannot be eradicated and can only be minimized. The use of high-quality hydraulic oil and hydraulic piping should be used to prevent the appearance of elbows, the use of high-quality pipelines, pipe joints, hydraulic valves, etc.

2, oscillation

The oscillation of the hydraulic system of the film forming machine is also one of its ailments。 Because of the high-speed movement of the hydraulic oil in the pipeline, the impact of the attack and the impact of the valve opening and closing process are the reasons for the oscillation of the system。 Strong oscillations can lead to faults in the control of the system, and some of the more elaborate instruments in the system can cause faults, leading to system problems。 Solution: The hydraulic lines should be fixed as much as possible to prevent sharp bends。 To prevent frequent changes in the direction of the flow, it is impossible to prevent the vibration reduction method。 The entire hydraulic system should have an excellent damping method, together with the impact of external sources on the system。

3, leaking

The leakage of the hydraulic system of the film forming machine is divided into internal leakage and external leakage. Internal leakage refers to the leakage process that occurs inside the system, such as leakage at both ends of the hydraulic cylinder piston, leakage between the valve stem and the valve body. Although the internal leakage does not cause the loss of hydraulic oil, due to the leakage, the established control action may be affected until the system is faulty. External leakage refers to the leakage between the system and the external environment. Hydraulic oil leaks directly into the environment, in addition to affecting the working environment of the system, it will also cause system pressure to cause problems. Hydraulic oil leaking into the environment is also a risk of fire. Solution: Use better quality seals to improve the machining accuracy of the equipment.
