What issues should be paid attention to when installing hydraulic components of hydraulic systems?

The following four aspects should be paid attention to when installing hydraulic components of hydraulic systems.
,Hydraulic universal testing machineBefore installation, the hydraulic components must be cleaned with kerosene. The test pressure can be twice the working pressure, or 1.5 times the use pressure. During the test, you should conduct it in grades. Do not immediately increase the test pressure. Check it once every step up.
Second, the directional control valve (the control element used to change the flow direction of gas or liquid in the pipeline is called the directional control valve) should ensure that the axis is arranged horizontally.
Third, check whether the sealing ring at the oil inlet and outlet meets the requirements. Before installation, the sealing ring should protrude from the installation plane to ensure a certain amount of compression after installation to prevent leakage.
Fourth, the tightening force of each fixing screw in the hydraulic system of the hydraulic universal test machine must be uniform, so that the installation plane of the component and the bottom plate plane of the component must be in good contact.http://www.hssdtest.com/
