Submersible double suction electric pump

Abstract

The invention discloses a submersible double suction electric pump which comprises an integral machine shell and a submersible motor. A wet submersible motor is adopted as the submersible motor. The integral machine shell sequentially comprises a water outlet segment, a motor segment, a work component segment and a water suction segment from top to bottom. The submersible motor is located in the water outlet segment and the motor segment. The water outlet segment comprises a water outlet shell. A drainage opening is formed in the top of the water outlet shell. A first cable is arranged on one side of the water outlet shell and is in electric wire connection with the submersible motor. The motor segment and the work component segment are provided with the same water cover. The work component segment comprises a volute and a double suction impeller. An exhaust hole is formed in one side of the volute. Through the adoption of the double suction impeller and the wet submersible motor, the surface of the submersible motor can be cooled easily, and the service life of the submersible motor can be prolonged; and the form of the double suction impeller is adopted, the water suction speed of one suction inlet is reduced, and the function of avoiding cavitation is effectively achieved by reducing the suction speed.

Description

technical field [0001] The invention relates to the technical field of submersible pump equipment, in particular to a submersible double-suction electric pump. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water and extracts groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. [0003] However, the submersible pump needs a huge range to transport the sewage, so it needs more power, which is easy to cause the motor to heat up and affect the service life, and the larger the range will also lead to faster flow, so it is easy to cause the submersible pump internal Cavitation phenomenon, in the cleaning process of some warehouses, submersible pumps need to be used to pump sewage, but because the sewage contains a certain weight of particles, it is easy to sink to t...

[0003] However, the submersible pump needs a huge range to transport the sewage, so it needs more power, which is easy to cause the motor to heat up and affect the service life, and the larger the range will also lead to faster flow, so it is easy to cause the submersible pump internal Cavitation phenomenon, in the cleaning process of some warehouses, submersible pumps need to be used to pump sewage, but because the sewage contains a certain weight of particles, it is easy to sink to the bottom of the water, and when the sewage is pumped, the particles will still remain in the warehouse At the bottom, the particles are not easy to clear, and follow-up manpower is still required to clean up, which affects work efficiency
