Sewage pump belongs to the centrifugal pump size, layout, principle and general centrifugal pump is like ordinary water pump is designed in order to get the highest efficiency of, that is to say, the water pump of hydraulic layout parameters is to obtain the best combination of the highest efficiency. The efficiency of sewage pump, which has special requirements of the pump can not be more than the same period of time the efficiency of the water pump.
Sewage pump, efficiency is lower than the main reason for the water pump is the widening of their flow channels. The value of the efficiency decrease is mainly related to the extent of the broadening. Sewage pump flow channel is widened to prevent the obstruction.
Sewage pump impeller, simpler than that of the water pump, retainer, so as not to when the dirty grass live, underneath the impeller and a serrated blade, to the conditioning, the end of the thread, cloth cutter broken and pulled out.
