Abstract
The invention discloses a draining pump. The draining pump comprises a pump body. The pump body is internally provided with a fan impeller. The exterior of the pump body is connected with a stator coil assembly. The two ends of the interior of the stator coil assembly are each provided with a bearing. A rotor shaft is installed in the two bearings. A rotor which is located between the two bearings is fixed to the rotor shaft. One end of the rotor shaft extends into the pump body to be connected with the fan impeller. A thrust ball bearing is installed on the end face of the rotor. According to the draining pump of the structure, due to the fact that the thrust ball bearing is installed on the end face of the rotor, the sliding friction between the end face of the rotor and the end faces of the bearings is converted into the rolling friction, so that a friction coefficient is greatly decreased, production heat is greatly lowered, the abrasion generated due to the relative motion friction between the bearings and the rotor at a high speed is lowered, and the service life is effectively prolonged.
Description
Technical field
The present invention relates to a kind of pump, particularly a kind of draining pump.
Background technique
Common draining pump is made up of rotor, impeller, coupling shaft sleeve, the pump housing, pump cover and stator coil.The rotor of draining pump gathers methyl alcohol by the ferrite of steel axle and cylinder type by mold injection to combine.This rotor structure is cylindrical, and two ends of rotor face covers the thick polyoxymethylene of one deck 1.5mm, and the heat distortion temperature of polyoxymethylene is 130 degree, also not wear-resisting.When draining pump load draining, rotor can move axially, and makes its end face can be close to the bearing face be fixed on the pump housing.When running up, the sliding friction that rotor end-face and bearing face produce because of relative movement and raw temperature of generating heat, the temperature of rotor end-face raises and makes that working of plastics hardness reduces, deliquescing, the wearing and tearing of aggravation contact surface, thus the working life shortening draining pump.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of draining pump, can reduce the wearing and tearing of rotor end-face, effectively increase the service life.
In order to solve the problems of the technologies described above, a kind of draining pump of the present invention, comprise the pump housing, be provided with Vane wheel in the pump housing, the pump housing is externally connected with stator coil assembly, and the inner two ends of described stator coil assembly are respectively arranged with bearing, in two bearings, rotor shaft is installed, rotor shaft is fixed with the rotor between two bearings, this rotor shaft one end is stretched in the pump housing and is connected with described Vane wheel, and described rotor end-face is provided with thrust ball bearing.
As the improvement of technique scheme, described thrust ball bearing comprises the pedestal being fixed on rotor end-face, this pedestal is fixed with pressing plate, pressing plate is provided with gland, is provided with some balls between described gland and pressing plate.
As the improvement of technique scheme, described pedestal is provided with the limiting board of inside arc-shaped bend, forms arc-shaped cavity between this limiting board and pedestal, described platen edge has the arc chimb embedding and fix in this arc-shaped cavity.
As the improvement of technique scheme, in the middle part of described pressing plate, there is through hole, described gland both ends of the surface have first, second arc crisperding respectively, and described first arc crisperding clamps fixing through described through hole, and described ball is arranged and between the second arc crisperding and pressing plate.
The invention has the beneficial effects as follows: in this draining pump structure, by the thrust ball bearing installed at rotor end-face, the sliding friction of original rotor end-face and bearing face is converted to rolling friction, significantly reduce friction factor and produce heat, decrease bearing and rotor in the fricative wearing and tearing of high speed relative movement, effectively increase the service life.
