Structural characteristics and application of trailer-type mobile pump truck

The trailer-type mobile pump truck is also called the traction-type mobile pump truck, which is mainly used for mobile drainage equipment by external force dragging or traction. The trailer-type mobile pump truck is mainly composed of a drawbar, a car base, and a diesel engine water pump unit. The unique design of the pump body and impeller flow path of the diesel engine water pump makes the pump unit of the trailer-type mobile pump truck no need to install like a clean water pump. Water diversion and bottom valve can also absorb and discharge water with large particles and long fiber impurities.

The trailer-type mobile pump truck is one of the modern and intelligent mobile drainage equipment developed by Better Technology. The main features are as follows:

1) The trailer-type mobile pump truck has the characteristics of simple operation, flexible maneuverability, and quick start-up.

2) It can be used for pipeline repair in some large communities.

3) The trailer-type mobile pump truck has strong suction and discharge capacity, and can suck and discharge sewage cleanly and quickly.

4) The open impeller design mode can avoid the clogging of the pump by particulate impurities.

5) It can work in mountainous areas without power supply, and the trailer-type mobile pump truck has a high head, which can transport water to places with high terrain.

6) The maintenance cost is low. When the impeller is stuck or entangled, the worn disc can be directly replaced.

7) Convenient and quick. It only takes 15-30 seconds to achieve normal operation on the job site, and there is no need for water injection.

    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.
