What should I pay attention to when installing hydraulic components of hydraulic universal test machine

Hydraulic universal testing machine is a large load, high availability of the universal testing machine, said the following note hydroulic components hydroulic universal testing machine installation, mainly in the following four aspects:

First, hydroulic universal testing machine, hydroulic components prior to installation, tocleaning with kerosene, two times the test pressure desirable work pressure, or the maximum pressure of one point five times. The test should be graded, not all of a sudden rise to test pressure, each level check once a.

Second, check the oil inlet and outlet seal ring is required before the installation, should highlight the installation plane sealing ring, to ensure the installation after a certain amount of compression, to prevent leakage.

Third, the directed control valve (control element to change gas or liquid flow is called thedirected control valve) should ensure that the axis is arranged in a horizontal position.

Fourth, the fixing screw hydraulic system of hydraulic universal testing machine of thetightening force should be uniform, so that the components of the installation plane and the bottom plane good contact element.

Hydraulic universal testing machineIt is a universal testing machine with large loads and high practicality. Let’s talk about the precautions for installing hydraulic components of the hydraulic universal testing machine. There are mainly four aspects:
Before installation, the hydraulic components of the hydraulic universal testing machine 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, 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.
Third, 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.
Fourth, the tightening force of each fixing screw in the hydraulic system of the hydraulic universal tensile tester must be uniform, so that the installation plane of the component and the bottom plate plane of the component should be in good contact.
