High-Speed Qjb-W Reflux Pum Submersible Sewage Treatment Agitator Mixer

This pump is a special equipment for mixed liquid return, denitrification and denitrification of secondary sewage treatment plants. lt can also be used for pumping and purifying ground drainage.Water, irrigation and control water system, recirculation in the process of wastewater treatment, or mud pumping loops where micro-lift and large flow are required.

1.Cable:The cable adopts special watertight cable;
2.Junction box:The junction box is fully enclosed and isolated from the surrounding liquidand stator box;
3.Motor:50Hz squirrel cage 3-phase submersible asynchronous motor,F-class insulation,protection class IP68.The motor is cooled by the surrounding medium;
4.Shaft:The shaft of the motor is made of stainless steel,and the rotor is tested for dynamicbalance;
5.Seal:The static seal is an O-ring.The shaft seal is a mechanical seal,which isolates the oilchamber from the surrounding medium;
6.Bearings:Imported bearings are used,and the designed service life can reach more than100,000 hours;
7.Oil chamber:oil is used to lubricate and cool the friction pair of the mechanical seal,andisolate the permeate;
8.Impeller:The impeller has three blades,the blades are wide and thin,the surface issmooth and swept back,efficient and unobstructed,and has a self-cleaning function;
9.Inlet cone:the purpose of the inlet cone is to form a better flow state;
10.Discharge joint:The discharge joint is used to fix the inlet tapered pipe on the outlet pipe;
11.Guiding device:The guiding device consists of two pipes(catheters)and an upper catheter clamp.
