Working principle of submersible pump

Submersible pumps are important equipment for deep well water lifting. When in use, the entire unit dives into the water to extract groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship adjustment, and can also be used for fountain landscape.

 

This article contains the following:

  • Working principle of submersible pump

  • Basic parameters of submersible pumps

  • Mechanical structure of submersible pump

 

1.Working principle of submersible pump

There are several types of submersible pumps, and the wire packs in the motor are oil-immersed and water-immersed, as well as dry. You must read the instruction manual before use. You can't make mistakes. If you don't use it for a long time, you must turn the impeller before use. Otherwise, you will burn it because you don't need to be stuck for a long time. Before starting the pump, the suction pipe and the pump must be filled with liquid. After the pump is turned on, the impeller rotates at high speed, and the liquid in it rotates along with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the ejected liquid in the diffusion chamber of the pump casing gradually slows down, and the pressure gradually increases. Outlet, discharge pipe outflow. At this time, because the liquid at the center of the blade is thrown to the surroundings, a vacuum low-pressure area is formed that is 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. It is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.

 

2.Basic parameters of submersible pumps

Including flow rate, head, pump speed, supporting power, rated current, efficiency, outlet pipe diameter and so on.

The complete set of submersible pump is composed of control cabinet, submersible cable, water pipe, submersible electric pump and submersible motor.

Submersible pump main purpose and scope of application

Including mine emergency rescue, construction drainage, agricultural water drainage and irrigation, industrial water circulation, drinking water supply for urban and rural residents, and even emergency rescue and disaster relief.

 

3.Mechanical structure of submersible pump

The submersible electric pump unit is composed of four parts: water pump, submersible motor (including cable), water pipe and control switch. The submersible pump is a single-suction multi-stage vertical centrifugal pump; the submersible motor is a closed water-filled wet, vertical three-phase squirrel cage asynchronous motor. The motor and the water pump are directly connected by a claw or single key cylinder coupling; equipped with different specifications Three-core cable; starting equipment is made of air switches with different capacity levels and self-coupling decompression pneumatics, and water pipes are made of steel pipes of different diameters, which are connected by flanges, and high-lift electric pumps are controlled by gate valves.

The upper part of the submersible motor shaft is equipped with a labyrinth sand control device and two back-mounted skeleton oil seals to prevent quick sand from entering the motor. The submersible motor uses water-lubricated bearings, and the lower part is equipped with a rubber pressure-regulating film and a pressure-regulating spring to form a pressure-regulating chamber to regulate the pressure change caused by temperature; the motor winding is insulated with polyethylene, nylon household water-resistant electromagnetic wire, and the cable connection method In the cable joint process, the joint insulation is stripped of the paint layer, and the joints are connected separately, and the welding is firm, and the raw rubber is used to wrap one layer. Then wrap 2-3 layers with waterproof adhesive tape, and wrap a layer of rubber (bicycle inner tube) with 2-3 layers of waterproof tape or water glue to prevent water leakage.
