We introduce a block share some hydraulic pressure testing machine function and operation,we first introduce the hydraulic system, the fuel tank through the filter net oil is sucked into the pump, the pump oil pipe to the oil supply valve, when the oil feeding hand wheel is closed, because the oil pressure and the piston pushed away, the oil from the oil return tank,oil feed handwheel when opened, the oil fluid through tubing into the working cylinder, and then through the pressure oil through the oil return valve to tank.
Specific operation, we also finishing it, we hope to help.
1, unscrew the oil return valve, so that the lower platen down, take out the test samplecrushed.
2, record the need to load value, and described the pen up.
3, the sample after crushing, closes the valve, and stop the oil pump motor.
4, according to the requirements of experiment loading speed, slowly unscrew the oil supply valve for loading test.
5, use the beam motor, the upper pressing plate dropped from the sample of about 10mm,and then rotate the handwheel on the cross beam, the upper pressing plate in contact with the sample surface.
6, the active and passive needle needle adjustment to zero, close the oil supply valve.
7, start the oil pump, the oil supply valve, so that the plate under the wheels out of orbit of about 10mm.
8, in the depiction of drum drum roll pressure recording paper, this just when needed.Hydraulic pressure testing machine operation process
9, according to the samples required measuring range, on a swing rod hung or disassembledthe pendulum thallium, and the buffer valve handle on the reticle alignment mark.
10, the lower pressure plate is pushed to the testing machine, and alignment.
11, the total switch on the power, the specimen is put in with the plate.
