IS vertical pipeline pump

Submersible pump is an important equipment for deep well water extraction.

When using the unit into the water, the extract to the surface of groundwater, water is life, mine emergency rescue, industrial cooling, farmland irrigation, seawater lift, ships, can also be used for fountains landscape.

The working principle of

There are several types of submersible pumps. The cables in the motors are oil immersed, water immersed and dry.

Before use must read manual first, cannot make a mistake, do not use for a long time, must be used before the impeller must be turned, otherwise will burn a bag because of long-term need not stick dead.

Before opening the pump, the suction pipe and the pump must be filled with liquid.

After open pump, high-speed rotating impeller, the liquid with the blades rotate together, in under the action of centrifugal force, fly away from the impeller to injection, injection of the liquid in the pump shell gradually spread of indoor speed slow, pressure increase gradually, and then from the pump discharge, the discharge pipe flow.

At this point, in the center of the blade due to liquid was dumped into the surrounding formation is no air and no liquid vacuum low pressure area, fluid in the pool liquid under the action of atmospheric pressure on surface of the pool, the suction pipe into the pump, the liquid is continuously from the liquid pool was sucking up and continuously from the discharge pipe flow.

The submersible electric pump unit consists of four parts: water pump, submersible motor (including cable), water pipe and control switch.

The submersible pump is a single-suction multistage vertical centrifugal pump.

The submersible motor is a closed, water-filled, vertical three-phase squirrel cage asynchronous motor.

Equipped with three core cables of different specifications;

The starting equipment is made of air switches of different capacity levels, autocouple decompression pneumatic devices and pipes of different diameters, with flange connection and gate valve control for high-lift electric pumps.

The upper part of the submersible motor shaft is equipped with labyrinth sand control device and two return assembly frame oil seals to prevent sand flow into the motor.

The submersible motor adopts water-lubricated bearing, and the lower part is equipped with rubber pressure regulating film and pressure regulating spring, forming a pressure regulating chamber and adjusting pressure changes caused by temperature.

Motor winding using polyethylene insulation, nylon sets of water resistant electromagnetic wire, cable connection according to the cable joint process, scrape off the joints of the paint layer, respectively connected and the welding is firm, use raw rubber layer.

Wrap 2-3 layers of waterproof adhesive tape around the bread and 2-3 layers of waterproof adhesive cloth on the bread or wrap one layer of rubber (the inner tube of the bicycle) with water adhesive to prevent water seepage.

Each stage of the submersible pump is fitted with a rubber cap;

The impeller is fixed on the pump shaft with a vertebral sleeve.

The guide shell is threaded or bolted together.

The upper part of high lift program submersible pump is equipped with check valve to avoid the damage caused by stop water hammer.

The motor is sealed with precision bolt and cable outlet with rubber gasket.

The upper end of the motor has a water injection hole, there is a vent hole, and the lower part has a water outlet hole.

The lower part of the motor is equipped with upper and lower thrust bearings, which have grooves for cooling, and its stainless steel thrust plates for grinding, bearing the upward and downward axial forces of the pump.

The choice of submersible pump before use is very important. The type of water pump should be selected according to the actual situation of water source, working time and pump water quantity.

First of all, the head should be greater than the difference between the intake and outlet.

Second, pump flow to meet the drainage and irrigation requirements.

(1) environmental requirements for use

1. Safe and reliable power supply.

2. The difference between the outlet pipe and the water surface of the sink should be less than the head.

Choose relatively clean water sources.
