Pump industry suppliers to tell you: submerged pump mainly have the following parts

submerged pump has the following parts:

1, the impeller is the key of submerged pump parts.

according to fluid absorption methods of different impeller can be divided into single suction and double suction type two kinds. Single suction impeller structure is simple, the liquid can only from one side suction. Double suction impeller can symmetrically on both sides from the impeller suction liquid at the same time, it not only has a larger liquid absorption ability, and basically eliminated the axial thrust.

according to the impeller blade geometry, the blade can be divided into after bending, radial and the former three. Because after the curved blade can is advantageous to the fluid kinetic energy is converted to static pressure, so widely used; Radial blade is mainly used in partial emission pump and non-clogged pumps; Before the curved blade seldom applied in the submerged pump.

2, guide vane and the pump body in order to reduce the left liquid directly into the pump impeller caused by impact energy loss, sometimes in between the impeller and the pump shell device with a fixed blade wheel. Roller blades made of liquid into the pump shell gradually turned to continuously expand and flow path, make part of the kinetic energy is converted to static pressure can effectively. Multi-level submerged pump usually are installed on guide.

3, due to the water pump shaft rotation shaft sealing device fixed pump shell, in the shaft and the pump shell contact must have a certain gap. In order to avoid the water pump along the clearance leakage in high pressure liquid, or to prevent outside air into the pump from the opposite direction, you must set up the shaft sealing device. Submerged pump shaft sealing device is stuffing box and the mechanical seal. Two ring end face of the relative rotation by spring force against each other, have the effect of the seal. Mechanical seal is suitable for sealing occasions with higher requirements, such as transportation acid, alkali, inflammable, explosive and poisonous liquid.

Getting submersible pump from an idea to production is a complex process. It involves significant research, time, planning and patience. But with the right information, the right resources and the right product, it's possible.
The trend toward using pool cover drain pump submersible pump to ease winter cover pump, once established, soon extended into such additional fields as pool cover drain pump and winter cover pump.
