The parallel connection of fire pumps means that two or more fire pumps supply water to the fire water supply system at the same time. The reason is very simple. The parallel connection of multiple fire pumps increases the flow.

So in the case of series and parallel connection, what should we pay attention to?

When the fire pumps are connected in series, it is best to use fire pumps of the same model and specification in the selection, so as to avoid the impact and damage to the equipment due to differences in model and power. In terms of control, the front fire pump should be turned on first according to the direction of water flow, and then the back fire pump should be turned on. If the fire pumps are connected in series, it is better to use multi-stage pumps in the selection of fire pumps.

In the selection of parallel fire pumps, it is best to choose fire pumps of the same model and specification, so as to avoid the different outlet pressures of the fire pumps during work, resulting in unstable work.

In order to keep the fire pump from losing its chain in an emergency, daily maintenance is very important. After understanding the series and parallel connection of fire pumps, let's talk about how to maintain fire pumps in daily use?

We all know that the fire pump is a piece of equipment that is likely to be useless after its service life. This is a very common situation, but once it is used, it must not make mistakes. Therefore, in order to ensure that the fire pump can start normally in an emergency, we should conduct a test on the output flow and pressure of the fire pump every quarter, manually start the fire pump once a month, and check the power supply. Conditions automatically start the fire pump, check the oil volume of the oil storage tank every week, and observe the power of the starting battery of the waterproof pump every day. Of course, in order to do a better job of inspection, corresponding records should be made for each inspection.
