Starting and stopping methods of fire pump
Thread Content
In Chapter 11, Control and Operation, of GB50974-2014, the methods for starting and stopping fire pumps are mentioned on several occasions. I have some doubts regarding this, and I hope the experts can clarify them: 1 11.0.5 Fire pumps should be able to be started and stopped manually as well as automatically； 2、11.0.7 Article 1: The fire control cabinet or control panel shall be equipped with manual direct start buttons connected via dedicated wires ； 3. 11.0.8 Fire pumps and pressure stabilization pumps shall be equipped with local manual start/stop buttons, as well as protective devices ； 4. 11.0.12 The fire pump control cabinet shall be equipped with a manual mechanical start function, to ensure that personnel with appropriate authority can start the fire pump in emergency situations when there is a fault in the control circuits within the cabinet. It should operate normally within 5 minutes of the alarm occurring in manual mode. I would like to ask the teachers: how many different ways are there to start and stop a fire pump? Can you summarize it? I’m not sure if there are any repetitions among the above start/stop methods? Since these provisions are still mandatory, I want to find out
In short: local and remote
In short: local and remote
In short: there are two options, local start/stop and remote start/stop
Remote automatic, remote manual, proximal manual, mechanical start
What is described in the standards does not conflict with each other, nor is it repetitive； The methods of starting it are basically manual start/stop on-site, automatic start, start via the control cabinet in the control room, or manual start
1. The fire pumps and fire pressure stabilizing pumps mentioned in the post refer to two different types of fire pumps; in systems equipped with fire pressure stabilizing pumps, the fire pumps do not operate during normal times, while the fire pressure stabilizing pump operates. It can automatically switch on the fire pump when a large volume of water is required for firefighting during a fire. 2. Every pump requires both manual and automatic start functions. 3. Regardless of the type of fire protection system, fire pumps must have an interlocking function. General condition interlocking activation is a mandatory inspection item during fire safety inspections
