sewage pump belongs to non-clogged pumps, has a variety of forms: such as diving type and dry type two kinds, the most often dive type for submersible sewage pump wq type, the most common dry sewage pump as w type horizontal sewage pumps and wl type vertical sewage pump two. it is mainly used in transporting urban sewage, feces or liquid contains fiber. confetti of solid particles, such as the medium is often transport medium temperature is not more than 80 ℃. because be transported medium contains wrapping easily or gather bundle of fiber content. so the pump flow easily jams, pump once clogged will make pump can not work normally, and even burn motor, causing the sewage poorly. to city life and environmental bring serious influence. therefore, resist plugging sex and reliability is the important factor of sewage pump actor. and other pump impeller, and water pressure, as is sewage pump room, two core components. the performance of the advantages and disadvantages, means the pump"s performance is superior, sewage pump anti-clogging performance, efficiency, and the cavitation performance of the abrasion resistant properties, mainly by leaf pump and water pressure room two components to guarantee.

sewage pump structure and performance characteristics 1, the structure of impeller type: the impeller"s structure is divided into four categories: vane (open, closed), swirling, port type, (including single port and shuang liu tao) spiral centrifugal four, open impeller manufacturing convenient open half, when the impeller caused inside clogged, can easily cleaning and maintenance, but in the long run, in the particles will darken the abrasion vane and water pressure indoor wall, thus make the gap increase inefficient. and the increasing gap would damage the differential pressure distribution on the leaf. not only produce the massive vortex loss, and surely will make the pump axial force, at the same time, because of increased increased, the liquid flow between the flow pattern stability have been destroyed and vibration generation pump impeller not easily, the type of conveying contain big particle and long fiber medium, from the performance of speaking, this type of the impeller adiabatic efficiency is low, the highest efficiency about 92% of closed impeller as common, high-lift curve are relatively flat around. 2, swirling impeller: using this type of the impeller pump impeller, because some or all from water pressure chamber contraction flow. so non-clog performance is good, the particle ability and long fiber by skills. particles in water pressure indoor flow vortices generated by rotating impeller movement driven, suspending sex particles itself doesn"t generate energy, just in the flow and liquid exchange energy. in flow process, suspended sex particle or long fiber not and leaf contact, leaf abrasion conditions of lighter, does not exist for abrasion and increase the gap in the long run, will not cause the serious decline, the efficiency of the impeller pump using this type of suitable for pumping contain large particles and long fiber medium. from the performance of speaking, the impeller adiabatic efficiency is low, is only about 70% of the average closed impeller, high-lift curve are relatively flat. 3, closed impeller: this type of impeller normal with higher efficiency. and in the long term operation conditions are stable, with this type of pump impeller axial force, and can in smaller before setting on vice blade flat. on the front cover, vice blade can reduce the vortex loss and impeller imports of sealing ring wear particle. the vice hougaiban blade is not only the axial within balance effect, and can prevent suspended sex particles into the mechanical seal chamber of mechanical seal protection. but this type of the impeller, easily without plugging sex differences in pumping roots, unfavorable containing large particles (long fiber) end after the sewage medium. 4, port type impeller: the impeller belongs to no leaves impeller, impeller port is a from of a crooked imported to export the port. so suitable for pumping contain large particles and long fiber medium. fight plugging the gender is good. from the performance of speaking, this type of high efficiency and ordinary impeller closed impeller differ not quite, but with this type of impeller pump head curve more steep drop. power curve smoothly, not easy the creation bears the super power problems, but this type of cavitation performance of the impeller than ordinary closed impeller, especially suitable to use in the pump pressure on imports. 5, spiral type centrifugal impeller blades of the impeller for distorted helical vane wheel body on the cone, from the suction along the axial elongation. this type of the impeller pump and has the displacement pump and centrifugal pump function, suspended sex particles in leaf, don"t hit pump shed obsolete in any place, so nondestructive sex good. less damaging to transport things. due to the spiral boost, suspended particles through sexual strong, so the using this type of pump impeller suitable for pumping contain large particles and long fiber medium, and high levels of medium. the destruction of conveyance medium in a strict occasions has obvious characteristic.
