The Information about Submersible Pump

Submersible pump is an important equipment for deep well –raising

water. It is a pump that places the pump directly in the water. When use, the entire unit sneakes into the water to work and extract groundwater to the surface. The purpose of the submersible pump is to sneak into the water and extract water to the place where the user needs. The submersible pump unit consists of four parts: water pump, diving motor, water pipe pipe and control switch. Let's understand the structure and working principle of the submersible pump.

  • The working principle of the submersible pump

1. What Is The Submersible Pump?

The submersible pump is a device dedicated to extracting water from the depths of the ground. During the use process, the entire equipment sinks into the bottom of the water to work, Then extract the underground water sources to the surface. Use of submersible pumps, the journey is very extensive.

Extraction of groundwater can also be used for rivers, reservoirs, canals, etc.

Water engineering. It is mainly used for farmland irrigation and human and animal water in the alpine areas. It can also be used for cooling, heat pump units, cold pump units, and cities.  Municipal, factories, railways, mines, and construction sites.

Depending on the demand, there are many classifications of submersible pumps, including deep well pumps, submersible axis flow pumps, large submersible pumps.

Hot water diving pumps, stainless steel diving pumps, diving spiral centrifugal pumps, etc. There are some submersible pumps that can only pump water with clear water, do not contain debris, or very small granules, such as deep well submersible pumps, hot water submersible pumps, etc. There are some submersible pumps to pump mud water, Rain and the lake, such as submersible sewage pumps, but the size of the particles should be strict, too big to drain. For its unique structural characteristics, the substance that can be pumped is compared large, you can pump live fish, potatoes, apples and so on.

2. The Structure of The Submersible Pump

The submersible pump unit is pump and diving motor (including electricity Cable), water pipes, and control switches are composed of most of them. The submersible pump is a single -level multi -level vertical centrifugal pump; the submersible motor is a closed filling and wet formula, vertical three -phase strange motor, motor and water pump directly through the claws or single -key cylindrical shafts; equipped with different specifications.

Three -core cable; the starting equipment is made of air switches with different capacity levels, auto -coupled pressure hypotoniac, and water pipes are made of steel pipes with different diameter. The flanges are connected. The upper part of the diving motor is equipped with a maze -type sandprofeer and two returns.

The skeleton oil seal prevent flowing sand from entering the motor. Diving motor use water lubrication bearing, the lower part is equipped with a rubber pressure regulatory film and a pressure -regulated spring to form a regulatory room to adjust the pressure changes caused by temperature; the motor winding uses polyethylene insulation, nylon households to water -resistant electromagnetic wire, cable connection mode according to the cable joint process processing process , Take off the joints and scrape the lacquer layer, connect it separately, the welding is firm, and the raw rubber rubbing a layer. Twitted 2-3 layers with waterproof adhesive tape, 2-3 layers of waterproof adhesive tape on the outer outside or packed a layer of rubber (tire in the bicycle) to prevent water seepage.

There is a rubber inheritance in each stage of the submersible pump; the leaf wheels are fixed with a vertebral sleeve on the pump axis. The upper part of the high lift submersible pump is equipped with a stop valve to avoid the crew damage caused by the stopped water hammer. The motor is closed, and the precision stop snail is used.

The bolt, the cable exit plus the glue pad for sealing. There is a water injection hole at the upper end of the motor, a firing hole, and a water pore of the lower part.

The lower part is equipped with upper and lower push bearing, and there is a groove on the bearing bearing for Cooling, and the stainless steel thrusting plate of the grinding, to withstand the upper and lower axis force of the pump.

3. The Working Principle of The Submersible Pump

There are several types of submersible pumps. The wire bags in the motor are oily and water -soaking. You must read the instructions before use. Do not make mistakes. If you don't need it for a long time, you have to turn the impeller before use.

Otherwise, you will burn the bag because you do not need to die for a long time.

Before the pump is turned on, the inhalation tube and the pump must be filled with liquid. After the pump is turned on, the leaf wheels rotate at a high speed. The liquid in it rotates with the leaves. Under the action of centrifugation, the impeller is shot outward. Exit, the discharge pipe flows out. At this time, at the center of the leaves, the liquid was thrown around the surrounding area, and there was no air .

There is no liquid vacuum low -pressure zone, the liquid in the liquid pool is large on the pool surface. 

Under the influence of the air pressure, the flowing tube flows into the pump, and the liquid is continuously sucted from the liquid pool and continuously flows out of the discharge pipe.
