Abstract
The utility model provides a water pump motor's waterproof construction, includes the skeleton oil blanket that centers on the coaxial setting of motor shaft and paste tight motor end cover, sets up the water proof dish on the motor shaft, the coaxial fixed firmly skeleton oil blanket that supports of water proof dish and motor shaft, the water proof dish includes along the discoid body of motor shaft radial projecting extension and sets up the fixed hoop at the body both ends separately. The fixed hoop that the water proof coiled one end supports firmly skeleton oil blanket, makes the skeleton oil blanket can not take place to shift, and the while sets up a plurality of water drainage tank on the body surface of water proof dish, coils synchronous rotation the under the drive at the motor shaft at motor water proof in service, and the pump shaft of water pump and the swing joint of pump body department are as taking place the seepage, and water can be followed the motor shaft and arrived the water proof dish to spiral at the water proof and change the line of production livingly to throw away under the centrifugal force effect, thereby inside preventing that water from entering into the motor, the security that has improved the water pump operation in -process.
Description
Technical field
The utility model relates to the technical field of water pump, the waterproof construction of a kind of pump motor.
Background technology
Fig. 1 is the external structure schematic diagram of centrifugal water pump in prior art.
The centrifugal force that centrifugal water pump is dependent on producing when impeller rotates is to carry the water pump of liquid.Centrifugal water pump of the prior art generally includes the pump housing 1, impeller, pump shaft, mechanical seal, pump cover 2, motor shaft 3 and motor 4, its middle pump body and pump cover be combined with each other and are being internally formed pump chamber, impeller is arranged in above-mentioned pump chamber, impeller interfixes with pump shaft, it is flexibly connected between pump shaft with pump cover and mechanical seal is set, pump shaft is mutually permanently connected with motor shaft, and motor shaft is the drive shaft of motor, is connected with external power source by terminal box and powers for water pump.Pump needs before being initiated by hydraulically full in pump chamber and its corresponding suction hose connected, and when pump shaft impeller rotates, liquid is rotated by centrifugal force and thrown away by blade, and the liquid making suction hose be connected constantly enters in pump chamber under the effect of pressure reduction.Motor shaft is passed in the motor end cap corresponding to water pump side, the position that passes at motor shaft arranges the outside framework oil seal fitted with electric motor end cap simultaneously, on the one hand outside framework oil seal stops that the lubricating oil in motor is excessive, on the other hand the effect covering motor shaft fairlead is also acted as, to prevent the water spilt in water pump cover from entering into the inside of motor along pump shaft and motor shaft.But outside framework oil seal easily causes displacement in water pump operation because of vibrations, causes outside framework oil seal cannot fit tightly with electric motor end cap, in turn results in motor internal water inlet.
Utility model content
The technical problems to be solved in the utility model is to provide the waterproof construction of a kind of pump motor.
The utility model is adopted the technical scheme that by solving technical problem present in known technology:
The waterproof construction of pump motor of the present utility model, including being coaxially disposed and be adjacent to the outside framework oil seal of electric motor end cap around motor shaft, arranges water proof dish on motor shaft, and water proof dish and motor shaft are coaxially fixing and prop up outside framework oil seal；Water proof dish includes along the disc-shaped body of the radially projecting extension of motor shaft and sets up the clips at body two ends separately.
The utility model can also use techniques below measure:
The multiple rhone of surface configuration of body.
It it is cambered surface bottom rhone.
Each rhone be dorsad motor shaft direction of rotation gradually open helical.
Corresponding to the clips edge of outside framework oil seal side is radially projecting, water fender is set.
The utility model has the advantage that with good effect:
In the waterproof construction of pump motor of the present utility model, motor shaft arranges water proof dish, the clips of water proof dish one end props up outside framework oil seal, outside framework oil seal is made to be shifted over, body surface at water proof dish arranges multiple rhone simultaneously, water proof dish synchronous axial system under the drive of motor shaft in motor runs, such as there is seepage in the pump shaft of water pump and the active connection place of pump cover, water can arrive water proof dish along motor shaft, and throw away under the centrifugal action that water proof disc spins produces, thus prevent water from entering into motor internal, improve the security during water pump operation.

Fig. 2 is the structural representation of the waterproof construction of pump motor of the present utility model；
Fig. 3 is the top view of the waterproof construction of pump motor of the present utility model.
Detailed description of the invention
Referring to the drawings and the utility model is described in detail by embodiment.
As shown in Figures 2 and 3, the waterproof construction of pump motor of the present utility model, including being coaxially disposed and be adjacent to the outside framework oil seal 7 of electric motor end cap 6 around motor shaft 3, motor shaft arranges water proof dish 8, water proof dish and motor shaft are coaxially fixing and prop up outside framework oil seal；Water proof dish includes along the disc-shaped body 9 of the radially projecting extension of motor shaft and sets up the clips 10 at body two ends separately.Clips and motor shaft are tightly fastened and clamping motor shaft, to avoid being subjected to displacement between water proof dish and motor shaft, make to remain synchronous axial system between water proof dish and motor shaft.
The multiple rhone of surface configuration 12 of body, is cambered surface bottom rhone, each rhone be dorsad motor shaft direction of rotation gradually open helical.When motor runs, water proof dish rotates with motor shaft, and the water spilt in the pump housing can flow along rhone under the influence of centrifugal force, and throws away from body edges.
Corresponding to the clips edge of outside framework oil seal side is radially projecting, water fender 11 is set.Water fender fits tightly with outside framework oil seal.
The above, it it is only preferred embodiment of the present utility model, not the utility model is made any pro forma restriction, although the utility model is open as above with preferred embodiment, but, it is not limited to the utility model, any those skilled in the art, in the range of without departing from technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, belong in the range of technical solutions of the utility model.
