The working principle of small submersible pump for deep well pumping

The small submersible pump is an important equipment for lifting water from deep wells. When in use, the whole unit is submerged in water to work. The groundwater is extracted to the surface, the domestic water industry is used to cool mines, rescue farmland, and irrigate seawater. The ship can also be used for fountain landscape hot water. Small submersible pumps are used for hot spring bathing. It is suitable for extracting groundwater from deep wells. Water works. It is mainly used for farmland irrigation and human and livestock water in high mountainous areas for central air conditioning cooling heat pump units and cold pump units for urban construction site drainage. Generally, the head can reach 1500 meters, and the pump is a machine that changes the pressure of the fluid in the volume or conveys the fluid. Machinery that sucks and discharges fluids. Relying on the working parts such as piston diaphragm, plunger gear or vane to make reciprocating or rotary motion in the pump body, the volume of several working chambers in the pump body is changed periodically to alternately suck and discharge liquid. It can lift, transport or compress fluids. Small submersible pumps are mainly used to transport liquids, including water and oil, acid and alkali liquids, emulsified liquid suspension emulsions and liquid metals, and can also transport liquids, gas mixtures and liquids containing suspended solids. The energy of the positive displacement pump periodically applies force to the interface of one or more mobile effective attachments, the liquid equivalent to the volume, which causes the pressure to rise directly to deliver the liquid through the valve or pipe until the pressure required by the pipeline.

The suction pipe and pump must be filled with liquid before the small submersible pump is turned on. After the pump is turned on, the impeller rotates at a high speed. The liquid will fly away from the impeller with the blades and shoot outwards. The pressure gradually increases and then flows out of the pump outlet discharge pipe. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface. The small submersible pump forms a vacuum low pressure zone with neither air nor liquid at the center of the blade due to the liquid being thrown to the surroundings. The liquid is like this continuous The ground is sucked up from the liquid pool and continuously flows out of the discharge pipe.
