The main advantage of the hand-held diesel fire pump is the high lift, which can reach 90 meters. It is generally used for fire emergency fire prevention, forest emergency fire prevention, and factory fire protection. When the diesel engine fire pump is working, the auxiliary impeller is together with the pump main shaft Rotating, the liquid in the auxiliary impeller will also rotate together, and the rotating liquid will generate an outward centrifugal force. On the one hand, this centrifugal force resists the liquid flowing to the mechanical seal, reducing the pressure at the mechanical seal. On the other hand, it prevents the solid particles in the medium from entering the friction pair of the diesel engine fire pump seal, reduces the wear of the mechanical seal grinding block, and prolongs its life. The auxiliary impeller of the diesel engine fire pump can not only play a sealing role, but also reduce the axial force. In the diesel engine fire pump, the axial force is mainly caused by the pressure difference force of the liquid acting on the impeller and the gravity of the entire rotating part. The direction of action of these two forces is the same, and the resultant force is formed by the addition of the two forces.

The number of impellers is different, and the head is also different: Generally speaking, a single-stage pump has only one impeller, while a multi-stage pump has two or more impellers, which enables it to suck water many times and segment it. processing, which greatly increases the lift. Therefore, under the same medium flow, the lift of the multi-stage fire pump appears higher.
