How to protect the hydraulic universal testing machine?

The frequency converter of hydraulic Universal tester machine is the application of frequency conversion technology and microelectronic technology, work way of power frequency by changing the motor to control the power of ac motor control equipment. Inverter is crucial in the application of hydraulic universal testing machine, therefore, be sure to do the protection work of the inverter.

1. Firstly, before the daily maintenance of the transducer of hydraulic universal testing machine, the total power supply of the equipment must be cut off;3-30 minutes (depending on the power of the frequency converter) in the inverter to show complete disappearance.

2, should pay attention to check the power grid voltage, frequency converter, motor and circuitry of the surrounding environment, remove dust converter internal, on a regular basis by strengthening equipment management as far as possible to reduce the failure rate of frequency converter.

3. In order to solve the related environmental problems of hydraulic universal testing machine inverter, a set of air conditioning system can be installed to improve environmental conditions with fresh air pressure.

4, in order to reduce corrosive gas corrosion of components on printed circuit boards, hydraulic universal testing machine also can request frequency converter manufacturers to anticorrosive processing of circuit boards, after the repair will spray preservatives, effectively reduce the failure rate, improve the efficiency.

5. While maintaining the hydraulic universal testing machine, carefully check the frequency converter, send the electricity regularly, and take the motor to work at the low frequency of 2hz for about 10 minutes to ensure that the frequency converter is working properly.
