Sewage submersible pump manufacturers supply I. Introduction sewage submersible pumps are widely used to transport civil engineering, mining industry, agriculture, forestry, fisheries and other operations contain Sewage, solid small particles, is a small-scale sewage movable carriage equipment. It features easy to use, efficient, clean and easy maintenance. Second, the use conditions ● pump outlet flow had more than ratings (used to develop within the limits prescribed); ● diving depth of no more than 5 meters declare when ordering; ● water temperature does not exceed +40 degrees Celsius; ● Ph value between 5-9; ● Motor dehydration running time not too long; ● sewage containing solid particles 5s volume ratio of less than 2% below the viscosity. ● Operating parameters of the flow range lift range caliber range power range 5-300 m / h 5-200 m 33-264MM 0.75kw-220kw three, disassembly sequence 1, the assembly of the motor: Stator - cover - outlet box - - rotor assembly (including press-fit bearings) - under cover - with the sleeve in place gently tap the rotor - Mechanical seal - oil chamber - to try to pressure - the oil chamber oiling - seals. 2, the pump assembly: the assembled motor impeller coat - washers - impeller nut - volute casing (volute) - Base - Headers - handle. Note that when assembled, each mouth should be painted only calcium-based butter. 3, pump disassembly by the reverse order of assembly.
