Structure of pressurized water chamber of sewage pump

Sewage pump used in the pressurized water chamber is the most common volute, built-in submersible pumps in the choice of radial guide vane or flow channel guide vane. Volute spiral, ring and intermediate type three.

Centrifugal pump (except self-priming pump) should be before the start of the pump and the inlet pipe filled with water, centrifugal pump before filling the water there are two main methods: one is the use of assembly bottom valve filled with water. Otherwise the pump is unable to lift the work of the centrifugal pump does not start after the water is often due to pump the air is not drained, the water has not been filled due.

Insoluble sulfur production process, the high temperature insoluble sulfur quenching liquid to be quenched by the quenching liquid to be quenched by the centrifugal pump to complete, because the quenching liquid has a more corrosive, with a pump to stop the pump frequently, so the operator of the Irrigation pump is quite critical of the urgent urge to change the cumbersome and primitive pump method.

After analysis and study, decided to take the following methods to change irrigation pump operation, thus avoiding the need to pump every pump before the trouble, as shown in Figure 1, in the centrifugal pump inlet before adding a keg, installation, Keg bottom is not lower than the highest point of centrifugal pump casing, open the pump from the keg above the flange hole filled with quenching liquid, and then sealed with a blind flange flange, so that as long as a pump, No need to re-irrigation pump, which greatly improved the operator's working conditions.
