Hydraulic universal testing machine will always encounter some emergencies in daily use, such as suddenly stopping working. What should we do?

1. If the motor cannot work due to non rotation, check whether the power supply or motor is broken

2. If the friction force of the force measuring piston increases or gets stuck in the oil cylinder, it shall be grinded with chromium oxide grinding paste until it is normal

3. There is a problem with the transmission system of the motor and lead screw. If the machine is driven by sprocket, it may slip or the chain may be broken. If it is driven by worm, it may be worn.

4. When the user did not pay attention to hygiene during the test, there were iron filings between the lead screw and the large nut, which squeezed the large nut

5. If the beam is not horizontal and does not work, the beam must be leveled before it can work.

6. The oil circuit system leaks oil seriously or the oil pipe is broken. First, check whether the joint of the oil circuit system is tightened. If it is necessary to replace the gasket, replace it in time. If the oil pipe is broken, it is necessary to replace the oil pipe with higher strength. In addition, observe whether the piston of oil delivery valve and overflow valve is jacked or installed reversely. eleven
