The pump will start to work when the pressure in the fire extinguishing system pipeline of EDJ small Fire Fighting water supply equipment drops suddenly. The first triggered pump is the jockey pump(pressure stabili-zation pump). The pressure stabilization pipeline of the jockey pump is allowed to start frequently within a certain range. In general, the pressure of the jockey pump is 1-1.5 bar higher than that of the main pump.

Answer: First of all, we must understand the relationship between pressure and lift: pressure = liquid density * g * lift (g = 0.981). In fact, the fire water pump can not only transport water, as long as the physical and chemical characteristics and water liquid are fine, but most of them transport water in daily life. The density of water is 1 ton per cubic meter. It can be obtained from the above formula : Pressure=1000*0.981*lift, pressure=0.981*lift, at this time the pressure and lift are almost the same, so whether we refer to lift or pressure, it can basically be regarded as a parameter.

The jockey pump of the jockey fire water supply system must be kept running at ordinary times to maintain the pressure of the pipe network. When a fire occurs, it should still be able to run for a period of time until the main fire pump is started. It must be set according to the main and standby pumps. pressure pump. Due to the need for the stabilizing pump to keep running, energy is wasted, and the stabilizing pump is in working condition for a long time.

Proper design and installation of suction and discharge piping are vital for the efficient operation of a fire pump system. The suction piping connects the fire pump to the water supply source, while the discharge piping carries water from the pump to the fire protection devices.

Key considerations for these piping systems include the sizing, material selection, and routing. Proper sizing ensures that water can be drawn from the source at the required rate, and the piping material must be compatible with the water and the environment. Piping routing should minimize friction losses and ensure that the system operates without cavitation or other issues.
