2. Operation
The oil delivery valve
can be opened wider when raising the workbench, so that the testbench can rise at a faster speed. When the sample is loaded, it can be opened according to the test It can be closed without reason by adjusting the specified loading rate of the sample, causing the load on the sample to suddenly drop, thus affecting the accuracy of the test data
The oil return valve
must be closed when loading, and no After the oil leakage sample breaks, slowly open the oil return valve to remove the load and return the piston to its original position.
