Because the society develops, a lot more and much more massive buildings seem. The structure of sizeable buildings is difficult, which brings considerably issues for fire protection and fire suppression. Spary fire pump would be the automatic fire extinguishing apparatus for massive buildings, and it offers safety for fire safty of big buildings. Automatic spary fire pump is controlled straight by the press switch from the water program or water flow indicator, as well as the Fire Center also can handle its on or off. vertical cantilever pump When a fire begins, the crystal ball around the hole of automatic spraying program breaks, and after that the hole starts to spraying water. The water present inside the water pipe pushes the blade of water flow indicator to create the speak to closed, connect circuits, and output electrical signal for the Fire Center. Commonly, a automatic spray fire fire comes with two pumps, 1 in use and 1 in reserve. The reserved a single can automatically place into operation when the functioning pump breaks. Inside the manage circuits, there is certainly functioning state selector switch by which you can actually manage which 1 is in use, and which 1 is reserved. In accordance with the fire closed impeller pump protection guidelines, spray fire program automatically cease the pump right after beginning for 1 hour, so the time relay TM004 set delay time is 1 hour, it electrify l hours later, the intermediate relay energy 20004 release, make the operating energy spray pump manage circuit, water pump stops operating. We use PLC to manage spray fire pump, so it may set many different protection hyperlinks in te approach effortlessly, and adjust the delay time conveniently. It diaphragm pump manufacturer may communicate with all the upper laptop or computer by PLC, and after that the Fire Center can monitor the operating situation of spary fire pumps straight. Increase the automation amount of fire protection program to lay a foundation for the networked fire manage method, in order that the entire method efficiency can retain steady and trustworthy.
