Abstract

The utility model provides a water pump mechanism of a motor hollow rotor shaft and belongs to the technical field of electrical equipment and machinery. The water pump mechanism consists of a motor, a motor hollow rotor shaft, a spiral impeller, a water outlet pipe connector, a water inlet and a water outlet, wherein the motor hollow rotor shaft is internally provided with the spiral impeller; the spiral impeller is fixed at the inner wall of the hollow rotor shaft; the water outlet pipe connector is fixed on a motor cover plate; the spiral impeller rotates along with the motor; and a water source is delivered to the water outlet. The water pump mechanism can be used for overcoming multiple defects that the existing water pump sucks silt and foreign matters, the impeller and a pump casing are blocked, and the motor and a capacitor have high possibility of being burned out; and according to the utility model, the water pump mechanism of the motor hollow rotor shaft is designed and the water pump mechanism has the characteristic that the motor is not blocked and stuck in rotation by the silt and the foreign matters entering the water pump.

Description

A kind of water pump mechanism of motor hollow rotor shafts

Technical field

1, the utility model relates to a kind of water pump, particularly a kind of water pump of motor hollow rotor shafts.

Background technique

2, generally comprise motor, intake chamber, impeller, water outlet composition at present existing water pump structure; There is very big defective in this structural design; Water pump vane and water pump shell exist gapped, and it is stuck that promptly water pump sucks silt, foreign material impeller and the pump housing, and motor, electric capacity burn easily.

The model utility content

3, to the problems referred to above, the utility model has designed a kind of water pump that adopts the motor hollow rotor shafts, does not receive the characteristics of extraneous water source silt, the stuck helical runner of foreign material when drawing water.

4, for realizing above-mentioned purpose, the utility model adopts following technological scheme.

5, a kind of water pump mechanism of motor hollow rotor shafts; Comprise motor, motor hollow rotor shafts, helical runner, titting water outlet, water intake, water outlet composition; It is characterized in that: helical runner is arranged on the motor hollow rotor shafts axle inwall; Helical runner changes along with motor, sucks the water source and is transported to water outlet.Titting water outlet is fixed in motor terminal cover plate and extraneous pipe in succession.

6, at work, helical runner has been fixed in axial wall in the motor hollow rotor shafts, silt, impurity to water outlet, do not receive extraneous water source silt, impurity to suck stuck impeller operation through the helical runner surface transport when drawing water.

Description of drawings

7, Fig. 1 accompanying drawing is the structure sectional view of the motor hollow rotor shafts of the utility model; Among the figure, 1 motor; 3 motor hollow rotor shafts; 4 helical runners; 5 titting water outlets; 6 motor two end cover plates; 7, water intake; 8, water outlet.

8, Fig. 2 is the helical runner and the sleeve rotor axial section of A-A cross section structure among the utility model Fig. 1;

Among the figure, 3 motor hollow rotor shafts; 4 helical runners.

Embodiment

9, the water pump structure of the utility model motor hollow rotor shafts is as depicted in figs. 1 and 2; Comprise motor 1, motor hollow rotor shafts 3, helical runner 4, titting water outlet 5, water intake 7, water outlet 8 compositions; Said helical runner 4 is fixed on motor hollow rotor shafts 3 inwalls; Titting water outlet 5 is fixed in motor terminal cover plate 6 and is connected with extraneous pipe, and when helical runner 4 changes along with motor 1, the water source is transported to water outlet 8.

10, at work, helical runner 4 is fixed in axial wall in the hollow rotor shafts 3, and silt, impurity arrive water outlet 8 through the surface transport of helical runner 4 when drawing water, and do not receive special advantages such as silt, the stuck impeller of impurity and motor operation.

11, specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but the spirit that can't depart from the utility model surmounts the defined scope of appended claims.
