Open fine water mist fire extinguishing system set up the necessity of pressure stabilizing pump system
Release time:
Jan 10,2022
Norms require closed water spray system pump group should be set up pressure stabilizing pump, but not open water spray fire extinguishing system to put forward clear requirements, in fact, open water spray fire extinguishing system should be set up pressure stabilizing pump, specific reasons are as follows:
First, the pressure regulating system can make the partition control valve to the pipeline between the pump group to maintain a certain pressure, is conducive to monitoring the pipeline and valve leakage.
Second, if there is no pressure stabilization system, all pipe networks are in the air state, the pump starts, you need to empty the partition control valve to the pump group between the pipe network air, air emission time becomes longer, which is more obvious for the delivery of pipeline longer; coupled with high-pressure water mist pump start-up time is longer, resulting in difficult to meet the design response time should not be greater than 30s requirements.
Third, set up after the pressure regulator system, partition control valve to the pipeline between the pump group is completely similar to the closed water mist system, partition control valve open, the pressure regulator pump can not maintain the pressure of the network, even if there is no fire alarm linkage system to start the pump instructions, water mist control cabinet can automatically start the main fire pump to extinguish the fire.
