In the use of hydraulic systems, to ensure that the hydraulic system can work reliably for a long time, what needs to be done? Dalan Hydraulics reminds you that you must strictly follow the following four aspects during design or use:
1, to prevent leakage.
1 External leakage is not allowed. Internal leakage is unavoidable, but the leakage cannot exceed the allowable value. If the leakage is too much, the pressure will not rise, and the liquid engine will not reach the expected force (or torque).
2 The amount of oil leakage is related to the pressure level, which will make the working parts unstable.
3 Due to excessive leakage, the volume loss is increased and the oil temperature is increased. In order not to cause excessive leakage, appropriate clearances should be provided between the relatively moving parts and appropriate sealing devices should be installed.
2, to prevent oil temperature is too high.
1 The oil temperature of the hydraulic system is suitable to maintain 15 ° C - 50 ° C.
2 too high oil temperature will bring a series of adverse consequences:
a. As the oil temperature rises, the oil will become thinner, the leakage will increase, and the system efficiency will decrease.
b. The oil works at higher temperatures and is prone to deterioration.
c. To avoid excessive oil temperature, in addition to measures to avoid oil heating (such as hydraulic pump unloading and volume control for high-power systems), consider whether the fuel tank has sufficient heat dissipation capability. .
d. If necessary, a cooling device can be added.
3. Prevent air from entering the system and drain the air that is mixed into the system in time.
1 Air entering the hydraulic system can cause adverse effects such as noise and oxidative deterioration of oil.
2 Measures must be taken to prevent air from entering, and the air mixed into the system should be drained frequently.
4. Always keep the oil clean.
1 The oil is mixed with impurities, which will cause the spool to get stuck, block the orifice or gap, and the hydraulic components will not work properly, and the relative moving parts will wear out.
2 In addition to the installation of oil filters and various devices to prevent external impurities from entering the system, the oil filter should be cleaned regularly and the oil should be replaced.
3 Hydraulic system should be cleaned when assembling various hydraulic components and pipes.
4 After the test, it is best to remove the hydraulic components and pipes, and then carefully clean them before installing them.
