Pulse test system
Shenyang Ziweiheng Testing Equipment

A pulse test system mainly performs internal medium circulation pressure pulse tests, and medium temperature and ambient temperature alternating tests for automotive pressure-bearing parts (cooling water pipes, new-energy vehicle motor controllers, cooling water plates, quick-plug connectors, etc). The test shows whether the piece can complete the number of cycles required by the standard, and the product quality and reliability.

Thanks to the unified design of the hydraulic station, pulse generator, ambient-temperature box, medium-temperature box and tooling fixtures, the test system from Shenyang Ziweiheng Testing Equipment has good stability, repeatability and sealing, and low noise. A hydraulic power station has a reasonable spatial layout and large space to ensure convenient repair and maintenance. It adopts electrohydraulic servo closed-loop automatic control, and the system fully meets its specified working procedures. It adopts an isolated liquid pressurizing cylinder as a pulse generator, and the pulse pressure output is controlled by electrohydraulic servo, which can realize various waveforms such as trapezoidal wave, sine wave and square wave.

The technology is a specially designed and developed medium temperature control system that can meet the requirements of the medium test temperature when the test medium is circulated or non-circulated. It uses Visual Basic to develop special control software that can realize closed-loop control, complete automatic control, automatic measurement and other functions during the test process. It is very reliable and can be constantly upgraded to suit the development of new testing machine measurement and control technology and changing test standards.
