Multistage Slurry
This Slurry progression in the desired impeller , the middle ( guide vanes ) installed at both ends of the suction and discharge sections segment , then these parts with staves to bear .
Pumps installed at both ends of the bearing , the axial force on the impeller balance hole , balance drum , balance disc and arranged symmetrically balanced impeller and other methods . Balance the disk structure is generally not loaded thrust bearings , pump head can be less than 700m dorsal blade balance hole or axial force balance . Liquids containing impurities or frequent starting of the occasion can be arranged symmetrically balanced impeller axial force method , in addition, extensive use of the balance disc or balancing drum structure .
Slurry body is a double structure , the inner and outer casing to maintain pressure of the pressure space is filled with high pressure water . Thus, the inner housing only by external pressure , the fluid pressure pump with the well sealed . Pressed out of the outer housing to withstand the pressure is equal to the internal pressure , and, because it is a simple cylindrical shape , the design, manufacture , maintenance is very easy .

Slurry in the field of application of sewage
slurry pump manufacturer in the sewage increasingly widespread application in the field of many of the domestic wastewater treatment plant sludge screw centrifugal pumps are used .
slurry pump manufacturer in the sewage increasingly widespread application in the field of many of the domestic wastewater treatment plant sludge screw centrifugal pumps are used .
Such as sewage treatment plant sewage treatment capacity of existing 450,000 t / d using enhanced biological nitrogen removal process based, supporting a 720m3 / d of sludge landfill ; outside the plant engineering including rain sewers 21km and two 2.0T / S sewage pumping station, in order to avoid clogging and thus adopt Slurry, each pumping stations designed to have three sets screw centrifugal pump 2 with a prepared , single pump flow 540L / s, head 7m, power 55kW. Body structures for the efficient handling of sewage settling tank into the mixing zone first chemical coagulant dosing with rapid stirring Pharmacy sewage mixed, then enter the flocculation zone dosing slow mixing polymer floc formation , and then entered the water from the bottom sediment area after separation of the inclined pipe treated water is discharged from the sludge sump area down to concentration .
Sludge from the sludge thickener concentration and convergence in the central pool of mud bucket , mud bucket portion of the sludge from the pump back to the flocculation zone sludge discharged to the sludge treatment system , return sludge that is not fully reacted Pharmacy further use could give full play to the role of pharmaceutical dosage savings .
Return sludge pumps and sludge pumps are used centrifugal pump , power of 55KW, flow of 1127m3 / h. Operation shows clogging the pump is not only difficult , but also avoids breaking return sludge floc sedimentation effect guaranteed .
