Trailer-type mobile pump truck has strong self-priming ability

Trailer-type mobile pump truck is also called mobile self-priming drainage pump station, and can also be referred to as mobile pump truck, pump truck, mobile pump unit, mobile pump station, etc. Trailer-type mobile pump truck is a kind of mobile pump truck developed by our company. A self-priming pump driven by a diesel engine is a pumping device with strong self-priming capability.
The trailer-type mobile pump truck adopts the axial return and external mixing type, and through the unique design of the pump body and impeller flow channel, it can not only need to install a bottom valve and irrigation water like a general self-priming clean water pump, but also can suck and discharge large solids And long-fiber impurity liquid, widely used in flood control and drought relief, municipal sewage discharge, emergency drainage and other fields.

A diesel engine is used to coaxially drive a generator and a water pump, so that a disaster relief equipment can simultaneously or separately carry out the operation of transmitting electric energy and pumping water. Aiming at the two operations of supplying power and pumping water, which have a high application rate in emergency rescue and disaster relief, the company has adopted innovative methods to develop the company’s new dual-function integrated pump truck for power generation and pumping for emergency rescue and disaster relief, which effectively solves the problems frequently encountered in emergency rescue and disaster relief activities. Difficulty in entering, narrow working area, and parallel pairing of various operations.

    When the diesel engine mobile pump truck is working, the diesel engine water pump relies on the high-speed rotating impeller, and the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump works, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation. When the impeller rotates rapidly, the blades make the medium rotate quickly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. While continuously inhaling liquid, it continuously gives the inhaled liquid a certain amount of energy to discharge the liquid. The diesel engine water pump just works continuously like this.
