The purpose and working principle of lifting the fire pump by hand

The original habit is called hand-lifting fire pump. It is a fire pump set that can be lifted with human hand and assembled with light engine. The hand-lifted fire pump set is composed of light gasoline engine or diesel engine and fire pump system. The overall layout should be reasonable and the structure To be compact, small in size, weight ≦ 100kg, vacuum sealing performance ≦ 2.6kPa, large vacuum ≧ 85.0kPa, diversion time ≦ 35.0s and other parameters, the whole machine consists of water pump, water diverter, gasoline, diesel engine and other components. The hand-lifting fire pump is mainly applicable to the fire extinguishing of fire fighting, various professional fire brigades, industrial and mining enterprises, county towns, villages and towns, etc. It is more advantageous in areas where fire-fighting vehicles cannot pass through, and hand-lifting fire pumps can also drain cockroaches, drought, green water, Ideal equipment for water supply and emergency disaster relief. Working principle Lifting the fire pump unit The whole machine is composed of a water pump, water diverter, gasoline or diesel engine. The engine is started first to drive the pump impeller to rotate at a high speed, and the water is taken from the inlet pipe by the vacuum pump vacuum or the exhaust type vacuum for 30 seconds. A water pump was introduced to generate pressure through a high number of rotations of the pump impeller, and then drained through the water outlet of the pump.
