Fire Nozzles And Fire Hose Dynamic Pressure Jet Testing Apparatus

1. Scope of application:

It is suitable for fire-fighting soft reel and fire nozzles spray test. Its design and manufacture refer to the standards of GB15090-2005 "Fire Hose Reel" and GB8181-2005 "Fire nozzles", using computer automatic control, automatic collection test Data, pressure control is precise, and formatted reports are automatically generated. The overall design is reasonable, the maintenance is convenient and fast; the automatic constant pressure, the slight leakage automatically replenishes the constant pressure; the high-pressure pipeline is made several times, and it is durable.

The working pressure is 0.20Mpa~4.0Mpa, and the flow rate is not more than 16L/S;

This instrument only includes fire hose reel jet test, fire water gun jet test and flow test;
