What do you need to do to ensure the long-term reliability of the hydraulic system?

In the use of hydraulic systems, to ensure that the hydraulic system can work reliably for a long time, what do you need to do? In the design or use process must be strictly in accordance with the following four aspects:

1, to prevent leakage.

External leakage is not allowed, internal leakage is inevitable, but the amount of leakage can not exceed the allowable value, if the leakage is too much, the pressure will not rise, the hydraulic motor can not achieve the expected force (or torque).

The size of the oil leakage is related to the level of pressure, which will make the movement of the working parts unstable.

(3) Due to excessive leakage, the volume loss increases, the oil temperature rises, in order not to leak too much, it should make the relative moving parts have an appropriate gap and install the appropriate sealing device.

2, to prevent oil temperature is too high.

① The oil temperature of the hydraulic system is suitable to maintain 15℃-50℃.

② Too high oil temperature will bring a series of adverse consequences:

A. Rising oil temperature will dilute oil, increase leakage, and decrease system efficiency.

b, the oil works at a higher temperature, easy to deteriorate.

C. To avoid too high oil temperature, in addition to taking measures to avoid oil heating in the design (such as hydraulic pump unloading and volumetric speed regulation for high-power systems, etc.), it is also necessary to consider whether the tank has sufficient heat dissipation capacity.

d, if necessary, can add cooling device.

4, always keep the oil clean.

(1) There are impurities in the oil, which will cause the slide valve to jam, block the orifice or gap of the throttle, so that the hydraulic components can not work normally, and the wear of the relative moving parts is aggravated.

In addition to installing the oil filter and various devices to prevent foreign impurities from mixing into the system, the oil filter should be cleaned regularly and the old oil should be replaced.

③ When assembling the hydraulic system, it is necessary to clean the various hydraulic components and pipelines.

After the test, it is best to remove the hydraulic components and pipes, and then install them after careful cleaning.
