How to make sure that the power supply working pressure of the fire water monitor is unsatisfactory? So in general, if everyone consults the professional and technical personnel of the manufacturer, it is concluded that the very simple method is to test the fire and water on the spot, such as 5L The working pressure of the power supply of the fire monitor is 0.6 MPa. If it exceeds, the reasonable maintenance of the longitude is 30 meters. Then it seems to be appropriate. Set an open flame in the area of 30 meters, and then start the fire monitor. It can be clear whether the working pressure is qualified if the fire accident is extinguished.
If the fire water cannon's long-distance gush cannot reach a distance of 30 meters, it means that the supply and demand balance of the automatic fire gun's pipeline working pressure is less than 0.6MPa. Then at this time, the rated power supply working pressure must be increased. Here It is proposed that everyone install a terminal water test device to check whether the working pressure of the tail end of the fire water monitor is qualified, and can query the working pressure status of the tail end of the pipeline at any time, anywhere, and then adjust the supply pressure of the centrifugal pump upward to the rated working pressure. Scaling is fine.
There is also a situation where the gushing distance exceeds 30 meters, so the result can not be used to extinguish the open flames. At this time, everyone will feel the pressure is too great, can the gushing be far away? Is this difficult? It is also necessary to integrate the working pressure bearing scope of the fire hose. Most 5L fire water monitors use DN50 flanges, so the working pressure that can be assumed is equal to the rated pressure of the fire water monitor. The internal working pressure is too large, and it will cause damage to the pipe fittings and equipment for a long time. Therefore, the working pressure must be adjusted to the rated value.
