3, Check the steering
If the steering is reversed, it is also impossible to pump water, we need to correct the steering to solve this problem.
4, Check the pressure out of the pipeline
If the pressure line is too thin or the line loss is too big, it will affect the water output of fire pump, find and switch the suitable pressure line.
5, Consider the conveying medium
When conveying some special media, such as hot or volatile media, we should reduce the suction range or use the backflow installation method to ensure that the media can be transported normally.
6, Check whether the suction pipe or fire pump is drained of gas
When there is gas in the suction pipe or fire pump, it will also affect the normal suction of the fire pump.
7, Whether to fill the liquid. Refill the fire pump can be.
