Abstract
The utility model relates to a submersible electric pump with a front impeller. The front end (the water inlet end) of a submersible electric motor is provided with water pumping impeller, and the water flow flows through a prearranged water guiding groove and carries away the heat generated by the electric motor when the electric motor operates. When the water is pumped out of the submersible pump, the water is pressurized. The utility model not only holds the favorable radiating performance of the electric motor, but also effectively improves water outlet lifting as the water outlet pressure is increased. The utility model has the advantages of novel design, reasonable structure, and convenient manufacture and refitting.
Description
The utility model is involved in Submerged Motor Pumps, particularly the Submerged Motor Pumps of impeller before being equipped with.
Existing Submerged Motor Pumps, impeller all are contained in motor back, i.e. waterexit end.Ubiquity two big drawbacks: 1. the motor heat dispersion is relatively poor, and working life is short; 2. the water outlet lift is not high.
The purpose of this utility model provides a kind of motor perfect heat-dissipating, the Submerged Motor Pumps that the water outlet lift is high.
The purpose of this utility model is achieved in that the front end at motor is that feed-water end is equipped with impeller, and the impeller front end is equipped with intake pipe and filter, and the rear end of motor is the waterexit end, and impeller and outlet pipe are housed successively.Motor is sealed in the housing of band tongue and groove.When the work of this Submerged Motor Pumps, the front end impeller draws water, and the housing of the band tongue and groove by sealed electric-motor is with the water waterexit end of making a gift to someone.The tongue and groove housing had both played the effect of water guide, took away the heat of motor again by flowing water, made motor keep good working performance; When flowing water during through the impeller of waterexit end, further increase hydraulic pressure, improved the lift of water pump effectively.
The utility model modern design, rational in infrastructure, be convenient to make and repacking, help implementing to promote.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is a plan view of the present utility model.
With reference to accompanying drawing, motor (4) is sealed in the housing (3) of band tongue and groove (5), identical impeller of direction (2) and impeller (8) are equipped with in motor (4) two ends, the two ends of housing (3) are connecting the outlet pipe (1) and the intake pipe (6) of different-diameter, and the feed-water end of intake pipe (6) is equipped with filter (7).
When submersible pump was worked, water flowed into intake pipe (6) through impeller (8) pressurization by filter (7), enters in the water chute (5) in the housing (3), when flowing into outlet pipe (1), pressurizes once more through impeller 2, is pumped by outlet pipe (1).
Claims (2)
1, the Submerged Motor Pumps of impeller before a kind of being equipped with is made of filter (7), intake pipe (6), outlet pipe (1), impeller (8), impeller (2) and motor (4), and it is characterized in that: the motor front end has impeller (2).
2, the Submerged Motor Pumps of impeller before according to claim 1 being equipped with, it is characterized in that: submersible pump housing (3) inboard has the water chute (5) of convex-concave.
