Corresponding extend is connected to interior water blocking side plate in portion.
The motor includes casing, cover and drive end bearing bracket, is realized and is fixed with bolt and drive end bearing bracket between casing and cover, preceding
End cap is fixedly connected with speed reducer.
Through-hole is provided between the impeller upper surface and two-by-two wind guide and heat dispersion piece.
The beneficial effects of the utility model are:
Compared with conventional art, in the process of work, impeller rotation drives water repellent blade to pull water out to the utility model
The water surface, the water section of extraction are beaten on block water plate and are kept off back, and during impeller rotation, the wind-guiding of impeller upper surface dissipates
Backing synchronous rotary simultaneously forms upward airflow lifting force, and the airflow lifting force of formation can will keep off return water by block water plate and dispel shape upwards
At water mist, so as to radiate to motor.
Compared with conventional art, the limbers of the utility model water extraction leaf on piece is set as trapezoidal shape and aperture is from lower end
It is gradually increased to upper end, when water is rotated and extracted out by water repellent blade, therefore the water of water extraction leaf on piece is in the position of limbers upper end
It can accelerate to flow out, to reduce the consumption of motor kinetic energy, while lower end section start be provided with water flowing inclined-plane, by water flowing inclined-plane
The angle that raises of water change, so that the flow direction angle of water is corresponded to the upper end of limbers, further speed up water by logical
Water hole outflow, to reduce the consumption of motor kinetic energy.
