The rational use of pressure fluctuation and the pressure switch
Cause the reason of pressure fluctuation is a lot in the pipeline, such as the change of cutting resistance, electromagnetic direction valve switch, etc., will cause the hydraulic impact in the corresponding line.When hydraulic impact happened, the peak pressure, often leading to or greater than the setting value.Therefore, in the design of hydraulic system, hydraulic impact should be avoided.If you know when the design of hydraulic system within the possible impact pressure high, the design of the whole system, especially to the proper use of pressure relay is helpful.
Due to many factors cause of hydraulic impact, is difficult to accurately calculate, so can only according to the agency work, seize the main contradiction are calculated.When the piston driven workbench execution of the heavier components, such as if a sharp change speed, is caused by the movement system of inertia hydraulic impact tend to be larger.Hydraulic impact when the pressure inside the duct in a short time, increase the delta P.
