The practicality of mobile pump trucks in urban flood control projects

Mobile pump truck, also known as mobile pump truck or mobile pump station, replaces the original fixed pump station. Because of its vehicle-mounted installation, it is convenient and fast to operate. The main application occasions are: no fixed pumping station and no power supply area, assault flood control and drainage, emergency rescue, agricultural irrigation, aquaculture water supply, temporary water transfer, cofferdam pumping, industrial and municipal drainage, replacement of rainwater pumping station, etc.

    The Emergency Drainage Mobile Pump Truck adopts an integrated design, is durable, and is equipped with a vacuum auxiliary system, which has the characteristics of fast water absorption and high efficiency. It is suitable for flood control and drainage, and is equipped with a mobile diesel engine self-priming pump, a trailer-type emergency drainage pump truck, a 4-wheel mobile pump truck, and a combination of diesel engine and self-priming pump, with manual and automatic control settings. The diesel engine self-priming pump integrates self-priming and non-clogging sewage discharge, adopting an axial backflow external mixing type. Through the unique design of the pump body and impeller flow channel, it does not need to install a bottom valve and a tank like a general self-priming clean water pump. It can be used for water diversion, and it can absorb and discharge liquid containing large solid particles and long fiber impurities. It can be used for municipal sewage discharge, flood control, drought relief, river pond breeding, light industry, paper making, textile, food, chemical industry, electrical industry, fiber, slurry and mixed suspension, etc. Compared with domestic similar products, diesel engine self-priming pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, energy saving, convenient use and maintenance, etc. The mobile pump truck has good mobility and simple operation, and has application market and development prospects.

    The diesel engine mobile pump truck is an intelligent control product, and the operation information is displayed in informational information. The running status display of diesel engine mobile pump truck includes: waiting, starting, fuel supply, starting, starting delay, idling delay, normal operation, cooling shutdown, emergency shutdown. The display of equipment operating parameters includes: water pump speed, water pump head, cooling temperature, lubricating oil pressure, water pump flow, running time, fuel stock, starting battery voltage and other parameters. Equipment protection settings include: overspeed, low speed, low oil pressure, high cooling temperature, low air temperature (below 4°C), low fuel level, low battery voltage, high battery voltage, uncalibrated speed signal, and water pump water pressure is too low and over Flow and other pre-alarms; no speed signal, overspeed, low speed, low oil pressure, high cooling temperature, start failure, shutdown failure, oil pressure sensor open/short circuit, water temperature sensor open/short circuit, speed sensor open/short circuit, water pump water pressure over Automatic alarm for low and over flow;

    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.
