Diesel trash pump is excellent product

The engine driven water pump integrates self-priming and non-blocking sewage. It adopts axial reflow and external mixing, and through the unique design of the pump body and impeller flow channel, the diesel trash pump can be installed like the general self-priming pump without installing the bottom valve and the tank. Water diversion, and can also absorb liquids containing large particles of solids and long fiber impurities, can be widely used in municipal sewage flood control and drought relief, mountain farm irrigation, river pumping and other diesel engine irrigation pump.

Compared with domestic similar products, the diesel dewatering pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance, etc. It is the first in the domestic sewage pump series. The technical performance indicators are leading domestically, reaching the international advanced level, with a wide application market and development prospects.

There are many types of engine driven water pump, of which, on the other hand, the water discharged by the impeller into the gas-water separation chamber flows back to the outer edge of the impeller through the left and right return holes. The water flowing back from the left return hole is directed into the impeller channel under the action of pressure difference and gravity, and is crushed by the impeller, mixed with the air from the suction pipe, and then squirted to the volute, and the vacuum pump is pumped. Pump gear pump corrosion-resistant pump acid-resistant pump fire pump flows in the direction of rotation. It then merges with the water flowing from the right return hole and flows along the volute. Because the liquid pump continuously hits the cascade in the volute, the diesel engine is continuously crushed by the impeller, and is stirred and mixed with the air to form a gas-water mixture, and continuously flows so that the gas and water cannot be separated.

The mixture is peeled off at the outlet of the volute by the tongue and enters the separation chamber along the short tube. In the separation chamber, the air is separated and discharged by the outlet pipe, and the water still flows to the outer edge of the impeller through the left and right return holes, and is mixed with the air of the suction pipe. This cycle is repeated, gradually draining the air in the suction line, allowing water to enter the pump and completing the self-priming process.

The internal hybrid diesel engine has the same working principle as the externally-mixed self-priming pump. The trailer mounted pump differs only in that the return water does not flow to the outer edge of the impeller and flows to the impeller inlet. When the internal self-priming pump is started, the return valve in front of the impeller must be opened to allow the liquid in the pump to flow back to the impeller inlet. The water is mixed with the air from the suction pipe by the high-speed rotation of the impeller, and the gas-water mixture is discharged to the separation chamber. Here the air is discharged and the water is returned from the return valve to the impeller inlet. Repeat this until the air is drained and the water is sucked up.
