Abstract
The utility model discloses a durable submersible pump. The durable submersible pump comprises a hollow pump body, wherein the upper end of the pump body is provided with a water outlet pipe, the lower end of the pump body is a water inlet end, an inner shell is installed in the pump body, a motor is installed in the inner shell, the lower end of the motor is provided with an impeller, a flow passage is formed by a gap between the pump body and the inner shell, the lower end of the flow passage is provided with a volute, a water inlet is formed in the middle of the lower end of the volute, vortex-shaped partition plates are arranged in the volute, and a water outlet end of the volute is divided into a plurality of volute outlets by the vortex-shaped partition plates. By adopting reasonable restructuring and especially dividing the flow passage of the submersible pump into a plurality of water flow passages through the matching of the vortex-shaped partition plates and flow deflectors, and according to the durable submersible pump, turbulent flow is reduced, the efficiency of the pump is improved, and the service life of the motor is prolonged as heat of the motor is quickly taken away by more effectively utilizing the radiating effect of water flow, so that the submersible pump is durable and has good economic benefits.
Description
Technical field
The utility model relates to a kind of submersible pump, particularly a kind of cooling effect of motor better, more durable submersible pump.
Background technique
Submersible pump is the draining pump that the pump housing and motor can be immersed in the water work, the motor of drives impeller is installed in the mode of sealing in its inside, utilizes the rotation of impeller, from the water intake suction water source, bottom of machine, waste pipe by the machine top discharges the water of suction again, reaches the purpose of draining.
Existing submersible type pump drainage effect directly relies on the power of motor, pump efficiency is not high, need heat radiation during its machine operation simultaneously, it adopts motor to fill the structure of cold oil on every side, coordinating the body water on every side of flowing through to keep straight on dispels the heat, the radiating efficiency of this structure is limited, and motor can not get well cooling, directly affects the working life of submersible pump.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of durable submersible pump.
The utility model solves the technological scheme that its technical problem adopts:
A kind of durable submersible pump, the pump housing that comprises hollow, described pump housing upper end is equipped with outlet pipe, described pump housing lower end is feed-water end, be provided with inner casing in the described pump housing, in described inner casing, motor is installed, the lower end of described motor is provided with impeller, space between the described pump housing and inner casing forms runner, described runner lower end is provided with spiral case, the middle part, lower end of this spiral case has water intake, is provided with eddy current shape cutting plate in described spiral case, and described eddy current shape cutting plate is divided into several spiral case outlets to the waterexit end of spiral case.
In order further to improve the water conservancy diversion effect, on described eddy current shape cutting plate, be provided with upwardly extending guide plate.
In order to guarantee the stress balance of feed-water end place impeller, the number of described spiral case outlet is six, and described each spiral case outlet is equally spaced.
The beneficial effects of the utility model are: this submersible pump is by rational structure of modification, particularly by eddy current shape cutting plate and guide plate, coordinate the runner of submersible pump is separated into to several flow channels, both reduced turbulent flow, improved pump efficiency, also more effectively utilize the thermolysis of current, take away rapidly the motor heat, improve motor working life, make submersible pump more durable, there is good economic benefit.
