Abstract
The utility model discloses a kind of motor seal member, comprise fan housing and fan blade, fan blade is arranged on motor, fan housing covers fan blade, also comprises that sealing ring, sealing ring are O type, fan housing central authorities are provided with exhaust vent, and sealing ring is arranged on exhaust vent, in fan blade incision sealing ring.Adopt technique scheme to make a kind of motor seal member that can raise the efficiency, reduce the wastage.By the sealing ring adding, in motor rotation, fan blade can be fitted fully with sealing ring, make air-flow that the inspiration of motor institute goes without leakage, sealing function by sealing ring all enters in the middle of fan blade the air-flow of motor, reduce loss, improved the efficiency of machine operation, by fan housing position being added to the method for sealing ring, can improve 4% to 43% to the efficiency of series excited machine.Sealing ring add the sealing that has improved motor, the motor working efficiency of increase, is sucking under the requirement that power is constant, the power of motor can be reduced, and reduces the energy consumption of motor.
Description
Technical field
The utility model relates to the field of sealing technology of motor air-out, particularly a kind of motor seal member.
Background technology
The series excited machine that prior art is produced has gap at tuyere position, air-flow has part air-flow to enter fan blade outside (as shown in Figure 1) while entering motor fan part, but the air-flow that enters fan blade outside is useless air-flow, to motor rotation without positive role, make on the contrary electric efficiency on the low side, loss is higher, most effectively can only reach 39%.
Be badly in need of at present a kind of motor seal member that can raise the efficiency, reduce the wastage.
Utility model content
In order to address the above problem, the utility model provides a kind of motor seal member that can raise the efficiency, reduce the wastage.
A kind of motor seal member in the utility model, comprise fan housing and fan blade, described fan blade is arranged on motor, described fan housing covers fan blade, it is characterized in that, also comprises sealing ring, described sealing ring is O type, described fan housing central authorities are provided with exhaust vent, and described sealing ring is arranged on exhaust vent, in described fan blade incision sealing ring.In fan blade incision sealing ring, can guarantee well agreeing with of fan blade and sealing ring, can in the process of running, not depart from, guarantee the effect of sealing.
In such scheme, described sealing ring is red steel paper sealing ring.Red steel paper is the converted paper that a kind of flintiness is very high, has good elasticity, resistance to wear, corrosion resistance, thermal endurance, mechanical strength, insulation property and machining moulding performance.The good red steel paper of elasticity can make fan blade can cut easily sealing ring.
In such scheme, described fan blade is aluminum alloy fan blade.Aluminium alloy is a most widely used class non-ferrous metal structural material in industry, and aluminium alloy both can reduce costs also can cut sealing ring easily.
In such scheme, described sealing ring is one-body molded.One-body molded more firm, be not easy fracture.
Advantage of the present utility model and beneficial effect are: the utility model provides a kind of motor seal member that can raise the efficiency, reduce the wastage.By the sealing ring adding, in motor rotation, fan blade can be fitted fully with sealing ring, make air-flow that the inspiration of motor institute goes without leakage, sealing function by sealing ring all enters in the middle of fan blade the air-flow of motor, reduce loss, improved the efficiency of machine operation, by fan housing position being added to the method for sealing ring, can improve 4% to 43% to the efficiency of series excited machine.Sealing ring add the sealing that has improved motor, the motor working efficiency of increase, is sucking under the requirement that power is constant, the power of motor can be reduced, and reduces the energy consumption of motor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 2 and Figure 3, the utility model is a kind of motor seal member, comprise fan housing 1 and fan blade 2, fan blade 2 is arranged on motor, and fan housing 1 covers fan blade 2, also comprises sealing ring 3, sealing ring 3 is O type, fan housing 1 central authorities are provided with exhaust vent, and sealing ring 3 is arranged on exhaust vent, in fan blade 2 incision sealing rings 3.
Sealing ring 3 is red steel paper sealing ring, and fan blade 2 is aluminum alloy fan blade.As shown in Figure 4, Figure 5, when the feature of sealing ring 3 and fan blade 2 materials coordinates them, can make fan blade 2 cut easily sealing ring 3.Sealing ring 3 is one-body molded, one-body molded more firm, is not easy fracture.
As shown in Figure 6, by the sealing ring adding, in motor rotation, fan blade can be fitted fully with sealing ring, make air-flow that the inspiration of motor institute goes without leakage, the sealing function by sealing ring all enters in the middle of fan blade the air-flow of motor, has reduced loss, improve the efficiency of machine operation, by fan housing position being added to the method for sealing ring, can improve 4% to 43% to the efficiency of series excited machine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
