Number pressure switch endurance test equipment, using constant pressure water supply system to increase the water pressure to 0.4 mpa, adjust the inlet water pressure to the water pressure to be tested, the water pressure to be tested on the control interface input, the test pressure data is adjusted automatically by the control system after the pressure changes, and the data are uploaded to the PLC precision ± 0.25% F. S, the test pressure switch contacts use fast connection, head connected to PLC, PLC according to the state of Io to judge the on-off state of the pressure switch, the operator can be selected for different positions, switch mode (normally on/Off) , turn-on time, turn-off time, test times, etc. 

Constant pressure control system: equipped with variable frequency pump, ensure output flow 30L/min, output pressure 4bar, equipped with an 80L water tank, water tank with a high and low water level alarm float switch, disconnect intake valve at high water level to stop filling, at low water level

Open the intake valve and fill the tank with water. Equipped with a pressure sensor, feedback constant pressure water pressure, accuracy ± 0.25% F. S.

Technical parameters:

1.Number of stations: 10 High Voltage Switch Test stations (life test) On-off time of each station

On-off count and other tests, test parameters are individually adjustable Switching time adjustable range (0-9999s)  Disconnect time adjustable range (0-9999s)  On-off count can be adjusted range (0-999999 times)  Connection pressure range (0-0.4 mpa) Breaking pressure range (0-0.4 mpa)  Number of stations: 10 High Voltage Switch Test stations (life test) 

2.The control interface displays the content: Current test mode  Turn on the pressure value  Disconnect pressure value  Cumulative number of times  Number of on-off times  Turn on time  Results Switch status, etc.
