【標(biāo)題】

So repeated cycle, gradually the pipe in the air drained, so that water into the pump, complete the self-suction process. Sewage pump sewage self-suction pump oil pump diaphragm pump screw pump gear oil pump internal mixed sewage self-suction pump. More water is needed to fill the entire pipe before starting. Bottom valves are often faulty due to inclusions or lax closure of themselves, and eliminating these failures can sometimes take a lot of labor, especially in winter. There are many structural types of sewage self-priming pump, among which, on the other hand, the water discharged into the gas-water separation chamber by the impeller is returned to the outer edge of the impeller by the left and right backwater flows. The left backwater hole flows back to the water under the action of pressure difference and gravity, shot into the impeller groove, and was crushed by the impeller, mixed with the air from the pipeline, dumped into the worm shell, vacuum pump liquid pump metering pump gear pump corrosion pump resistance pumps fire pump to the direction of rotation flow. Ordinary centrifugal pump at the bottom of the pipeline with the bottom valve and then the right backwater hole flow to the water confluence working principle and the external mixed sewage self-suction pump is the same.
