The working principle of the drainage pump truck mainly includes the following key steps:
Start the pump truck: After the pump truck is started, the engine drives the pump body to start working. The power of the engine is transmitted to the pump system through the transmission system (such as a drive shaft or chain).
Pumping out the accumulated water: The pump body draws the accumulated water into the pump through the suction pipe. The suction pipe is usually connected to the accumulated water area and sucks the liquid through the negative pressure.
Gas-liquid separation and self-priming effect: A negative pressure area is formed in the pump body. After the liquid is sucked in, the gas-liquid separation device separates the gas and liquid, and the liquid is pushed to the periphery of the pump, and the gas is pushed to the center of the pump. When the pump chamber is filled with liquid, the self-priming effect is formed, and the liquid is pushed to the outlet through the centrifugal device.
Compression drainage: The pump body compresses the sucked liquid and discharges it through the drainage pipe. This process involves the suction, transmission and discharge of liquid.
Circulation operation: The pump truck continuously performs the cycle operation of suction, compression, and drainage until the accumulated water is removed .
Differences in the working principles of different types of drainage pump trucks Mobile self-priming sewage pump truck: This pump truck sucks liquid through negative pressure to achieve gas-liquid separation and self-priming effect, and is suitable for discharging sewage, wastewater or liquid containing particles. It is characterized by simple operation, low fuel consumption, high vacuum, high head and large flow .
Flood drainage rescue pump truck: It is usually equipped with an efficient pumping system (such as a centrifugal pump or a plunger pump) that can handle a large amount of liquid in a short time. The centrifugal pump relies on the high-speed rotating impeller to generate centrifugal force to push the liquid to the outlet, while the plunger pump generates pressure through the movement of the piston to push the liquid .
Performance characteristics and application scenarios of drainage pump trucks Efficient drainage: The drainage pump truck can quickly drain the accumulated water, and is suitable for various emergency rescue drainage operations such as municipal administration, water affairs, mining, and emergency flood control.
