Downward sucking submersible electric pump

Abstract

The invention discloses a down-suction submersible electric pump, which belongs to the technical field of submersible electric pumps. The technical problem to be solved by the invention is to solve the problem that the submersible electric pump cannot work when the liquid level is lower than or below the water inlet in the prior art . The technical scheme adopted is: including the water pump and the submersible motor, the water pump and the submersible motor are arranged from top to bottom, the water inlet is provided between the water pump and the submersible motor, and the water outlet is provided on the top of the water pump; it also includes the shroud and the connecting piece, the water pump There is a shroud on the outside of the submersible motor; the connecting parts include the outlet pipe and the connection plate Ⅰ above the water outlet pipe and the connection plate Ⅱ below the water outlet pipe; the water outlet pipe is in communication with the water outlet on the top of the pump; Above the hood and the water pump, the shroud and the water pump are fixedly connected to the connection plate Ⅱ; the diversion channel for the upper part to seal the bottom water is formed between the shroud, the connection plate Ⅱ, the water pump and the submersible motor; the connection plate Ⅱ has a Exhaust device communicated with the diversion channel.

Description

technical field [0001] The invention relates to the technical field of a submersible electric pump, in particular to a down suction submersible electric pump. Background technique [0002] The submersible electric pump is a kind of water pump in which both the impeller of the pump body and the motor driving the impeller are submerged in water. There are two types for deep wells and working surfaces. The submersible electric pump for deep well supplies power to the motor through the cable extending into the well. It has a compact structure, light weight, and is easy to install, use and transfer; the submersible electric pump for the working face is a pump that connects a vertical motor and a water pump to work submerged in water. , has the advantages of small size, light weight, and convenient installation, and is widely used in farmland irrigation. [0003] The traditional ordinary submersible pump consists of a submersible motor and a submersible pump. The submersible pump...
