Description
Technical field
The utility model is related to a kind of circulating pump, more particularly to it is a kind of circulating water flow circulation passage is set, for motor and
The anti-card machine circulating pump of bearing lubrication.
Background technology
As shown in figure 1, circulating pump includes the pump housing and shield electric machine.Under normal circumstances, aperture, pump are opened up on the pump cover of the pump housing
The water of intracavitary is by the pressure in pump chamber, is entered by the hole on pump cover inside the housing of motor, to the bearing on rotor
It is lubricated and motor can be cooled down（Although circulating pump is commonly used to heating, for conveying hot fluid medium（Such as hot water）, but
It is that the temperature of hot water still can be lower than the motor temperature after operation a period of time）.Circulating pump is in use, substantial amounts of warm
Water is circulated in housing intracavitary, and meeting fouling in mantle cavity is shielded, rotation of the fouling to rotor and rotating shaft has an impact, even
There is card machine and damage.Meanwhile can have impurity in hot water unavoidably, impurity is entered in housing inner chamber by the hole on pump cover,
Certain influence be present to the flexible rotating of rotor, rotating shaft, be easily stuck in the component position of rotation, card machine occur.
The content of the invention
The purpose of this utility model is solve above mentioned problem existing for prior art and provide a kind of anti-card machine circulating pump,
The water of lubrication and cooling is provided by accessory impeller to housing inner chamber, that is, meets the cooling to motor and the lubrication to bearing；Again
The circulation formed by the gap then passed through between front and back bearings and rotating shaft, the flow of water is small, reduces and is produced in housing inner chamber
The possibility to scale, the appearance for even avoiding card machine is reduced, simultaneously as gap is smaller, the impurity in water is difficult to enter shielding
Inner chamber is covered, further reduces and even avoids card machine caused by impurity.
What above-mentioned technical purpose of the present utility model mainly solved by the following technical programs：Anti- card machine circulating pump, bag
Include motor and the pump housing, the motor is provided with stator, rotor, the housing being arranged between the stator and rotor, described turn
The rotating shaft of son driving, sets bearing in the rotating shaft, the pump housing includes pump case, covers the pump cover on pump case, be arranged on pump
Shell and pump cover enclose the impeller in the pump chamber to be formed, it is characterised in that accessory impeller are set on the impeller, the accessory impeller is set
On the impeller hub towards motor side, the rotating shaft drives wheel rotation, and the accessory impeller is rotated, made together with impeller
Hydraulic pressure is formed in pump chamber, hydraulic pressure promotes the water in pump chamber to form recirculated water between the housing and bearing, and recirculated water is used for
It is lubricated to electric motor temperature reduction and to bearing.By accessory impeller, the enough hydraulic pressure of form, water appropriate in pump chamber is forced by turning
The gap between fore bearing and rotating shaft on axle is flowed into housing inner chamber, and water passes through the rear bearing in rotating shaft from housing inner chamber
Gap outflow between rotating shaft, is flow back into pump chamber, the current returned of formation are to motor by the water stream channel of rotating shaft
Cooling and the lubrication of bearing is met；Because the gap between front and back bearings and rotating shaft is smaller, the flow of water is small,
The possibility that incrustation scale is produced in housing inner chamber is reduced, reduces the appearance for even avoiding card machine, simultaneously as gap is smaller, water
In impurity be difficult to enter housing inner chamber, further reduce even avoid card machine caused by impurity.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures：It is described
Accessory impeller includes outer rim and inner rim, the plural pieces blade being arranged between the outer rim and inner rim, the inner rim
For one section of the impeller shaft.Accessory impeller can not touch the inwall of pump cover, the front end of fore bearing is contacted with the water in pump chamber.
The side of the blade stands in the hub surface of the impeller.When accessory impeller is with wheel rotation, before promoting water to think
Bearing flows, and then accessory impeller region forms secondary pressure, absorbs the water in pump chamber, can and so on continue to provide water to fore bearing
Stream, current are entered in canned motor pump inner chamber further through the gap between fore bearing and rotating shaft.
Gap coordinates between the accessory impeller and the pump cover, the radius of the accessory impeller for the impeller radius 1/5 ~
1/3.The diameter of accessory impeller is determined in OK range, that is, is avoided colliding with pump cover, avoided accessory impeller oversized again,
Increase the burden of impeller unitary rotation, accessory lobes size of wheel again can not be too small, too small then to the motive force deficiency of water.
Gap, housing inner chamber between the pump chamber, bearing and rotating shaft and the passage being arranged in the rotating shaft are formed
Loop passage, the passage in the rotating shaft run through the both ends of rotating shaft.The current pushed by accessory impeller flow in loop passage,
Motor, and can lubrication front and back bearings can be cooled down.
The utility model has the advantage that：1st, by accessory impeller, the enough hydraulic pressure of form, force appropriate in pump chamber
Water is flowed into housing inner chamber by the gap between the fore bearing in rotating shaft and rotating shaft, and water passes through in rotating shaft from housing inner chamber
Rear bearing and rotating shaft between gap flow out, flow back into by the water stream channel of rotating shaft in pump chamber, the water returned of formation
Stream（I.e. powerful interior circulation）Cooling to motor and the lubrication of bearing is met；2nd, due to front and back bearings and rotating shaft
Between gap it is smaller, the flow of water is small, reduce in housing inner chamber produce incrustation scale possibility, reduce even avoid card machine
Occur.3rd, because gap is smaller, the impurity in water is difficult to enter housing inner chamber, further reduces and even avoids caused by impurity
Card machine.
