Classification and working principle of submersible pumps

Stainless steel cutting submersible pump, submersible sewage pump, WQK/QG belt cutting device sewage pump is mainly used for engineering sewage and domestic sewage.

(1) Used in construction sites, engineering foundation construction, municipal facilities, and waterworks.

(2) Sewage discharge from underground floors such as basements, civil air pits and subways of various high-rise buildings.

(3) Sewage treatment and circulating water transportation for small and medium-sized enterprises.

(4) Slurry slurry pumping from factories and mines such as food, paper, brewing, steel and non-ferrous metals, leather, textile, pharmaceutical, and cement plants.

(5) Chicken farms, pig farms, various aquaculture industries, fish ponds for pumping clear ponds, aeration, septic tanks, etc. Note: The main performance and data of wqk are the same as wqk/qg type except that without cutting device.

Stainless steel, cast iron submersible pump A very versatile water treatment tool. Unlike ordinary pumps, it works underwater, and most pumps work on the ground.

How the submersible pump works

The suction tube and pump must be filled with liquid before the pump is turned on. After the pump is turned on, the impeller rotates at a high speed, and the liquid rotates with the blade. Under the action of the centrifugal force, it flies outward from the impeller, and the liquid that is ejected gradually slows down in the pump chamber, the pressure gradually increases, and then the pump At the exit, the discharge pipe flows out. At this point, at the center of the blade, the liquid is drawn to the surroundings to form a vacuum low-pressure zone with neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure of the pool surface, and the liquid is continuous. It is continuously sucked from the liquid pool and continuously flows out from the discharge pipe.

Basic parameters of submersible pumps

Including flow, lift, pump speed, matching power, rated current, efficiency, outlet pipe diameter and so on.

The submersible pump consists of a control cabinet, a diving cable, a water pipe, a submersible pump and a submersible motor.

The main purposes and scope of application of submersible pumps include mine rescue, construction and construction drainage, water agriculture irrigation and drainage, industrial water circulation, urban and rural residents' reference water supply, and even disaster relief.

Classification of submersible pumps

As far as the medium is used, the submersible pump can be roughly classified into a clean water submersible pump, a sewage submersible pump, and a seawater submersible pump (corrosive).

The wqx series sewage sewage submersible sewage pump is mainly used for discharging domestic wastewater, sewage, human excrement and solid suspended solids and non-corrosive media containing short fiber paper scraps, wood chips, starch, sediment, ore particles, and pumped liquid. The temperature does not exceed 40 ° C, the density is not more than 1200 kg / m3, the pH value is ~ 9.
