Universal testing machine is a mechanical testing machine that can carry out many different tests such as tension, compression, bending and torsion. There are two common types of lever pendulum and hydraulic pendulum, which are mainly used for mechanical performance tests of metal and non-metallic materials. They are ideal testing equipment for industrial and mining enterprises, scientific research units, universities, engineering quality supervision stations and other departments. Next The technical personnel of our company will introduce the operation precautions and installation methods of the universal testing machine, let's understand it together.

1. Notes on operation of universal testing machine
1 During the test, if the oil pump suddenly stops working, the added load should be removed to reduce the pressure of the oil pump, and then restart the pump after inspection. Do not start the oil pump under high pressure.
2 During the test, if the electrical appliance fails, the start or stop button does not work, the power should be cut off immediately to stop the testing machine.
3 In order to prevent the sample from flying out and causing an accident, a protective plate can be made.
4 When using, pay attention to whether the pressure plate bolts on both sides of the wedge block of the upper and lower jaw seats are loose. Should be tightened at any time to prevent accidents caused by flying out of the pressure block.
5 Before driving, tighten the oil delivery valve to prevent the piston from rising suddenly and quickly.
6 The lifting and lowering of the beam is used to adjust the test space. If the wrong operation or wrong test block is pressed, the chain jumper in the drive mechanism and the moving beam will be stuck and other accidents will occur.
7 When the testing machine is installed, correctly connect the three-phase power line, and the zero line cross-sectional area is not less than 1.5 square millimeters. Connect the ground wire firmly, and connect the cable between the main unit and the screen display part.
8 Pay attention to the direction of motor rotation during the initial test run. If the direction is opposite, replace any two-phase power cord position.
9 Check whether the limit switch is flexible and reliable, whether the thermal relay current setting value is appropriate, and the specifications should be the same when replacing the fuse.
