Sewage pump classification
Sewage pumps can be divided into: submerged sewage pumps, pipeline sewage pumps, submersible sewage pumps, vertical sewage pumps, corrosion-resistant sewage pumps, acid-resistant sewage pumps, and self-priming sewage pumps.
The sewage pump models are: PW sewage pump and PWL sewage pump.
PW type sewage pump adopts the most common volute in the pressurized water chamber. In the built-in submersible pump, radial guide vanes or flow channel guide vanes are mostly used.
PWL sewage pump impeller and pressurized water chamber are the two core components of the sewage pump. The pros and cons of its performance also represents the pros and cons of the pump.
With the progress of society, the continuous improvement of people's living standards and the strengthening of environmental protection awareness, sewage pumps have been familiar to people, and the scope of application has become wider and wider.
Of course, the sewage pump is just an application name. In fact, the rubber-lined slurry pump is very good as a horizontal sewage pump. In the treatment of industrial sewage, because the sewage contains acidic or alkaline substances, rubber-lined pumps are widely used. According to some application cases in the pump industry, the use of rubber jackets and metal impellers in rubber-lined pumps can not only achieve the high pressure and efficiency of metal pumps, but also give full play to the corrosion resistance of rubber materials. In the treatment of urban sewage, a filter screen is generally added in front of the sewage treatment tank to block fiber windings and the like before the suction port of the pump, so that it cannot enter the pump cavity, so that the pump can work better and have a longer life. long.
