Abstract
The utility model relates to a short shaft for impeller rotor dynamic balancing experiments. The short shaft for the impeller rotor dynamic balancing experiments comprises a short shaft body and an impeller rotor axial fixing mechanism which is arranged on the short shaft body. The short shaft for the impeller rotor dynamic balancing experiments is simple in structure, can be used for experiments only need independently installing with an impeller, solves the problem that direct use of a water pump shaft for impeller dynamic balancing experiments is inconvenient, and is not only convenient to assemble and disassemble, but also is high in efficiency.
Description
Technical field
The utility model relates to water pump, particularly relates to a kind of minor axis for the vane rotor experiment of dynamic balancing.
Background technique
Pump impeller is around the pump shaft rotation time, and non-uniform mass relative owing to it and this axle axis produces centrifugal force.This uneven centrifugal action can cause vibrations on axle bearing, produce noise and accelerate bearing wear, so that have a strong impact on overall performance and the working life of water pump.According to the GB9239 standard: 1. pair single-stage pump, the rotor of two stage pump is during all working speeds 〉=1800 rev/min, as long as dynamic balancing should be done in D/b＜6 o'clock.2. to multistage pump and combined rotor, no matter working speed how much, should be done the dynamic balancing of combined rotor.(D represents the diameter of rotor, b represent between two rectifying planes of rotor apart from size)
The space of the experiment porch of general commonly used experiment of dynamic balancing machine is limited, and according to the selected water pump spindle of different performance requirements usually inconvenience be directly used in the experiment of dynamic balancing of impeller.The length that mainly is axle can exceed experiment porch, unfavorable carrying out with testing.
Summary of the invention
The utility model provides the vacuum removal method of a kind of passenger car inner decoration spare harmful poisonous substance and volatile organic matter for the deficiencies in the prior art.The technological scheme that the utility model adopts is as follows:
A kind of minor axis for the vane rotor experiment of dynamic balancing is characterized in that, comprises minor axis body and vane rotor axial fixing mechanism, and described vane rotor axial fixing mechanism is located on the described minor axis body.
Aforesaid a kind of minor axis for the vane rotor experiment of dynamic balancing, wherein, described vane rotor axial fixing mechanism comprises for the baffle plate that axially blocks described vane rotor with for the nut that axially presses described vane rotor, described baffle plate is fixed on the described minor axis body, and described nut is threaded with described minor axis body.
The utility model is simple in structure, and only needing to assemble separately impeller can test, and has solved water pump spindle inconvenience and has been directly used in the problem that dynamic balance of impeller is tested, and is not only easy to loading and unloading, and efficient is high.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is that the utility model is at the structural representation of dynamic balance running state.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of minor axis for the vane rotor experiment of dynamic balancing comprises minor axis body 110 and vane rotor axial fixing mechanism 120.
Vane rotor axial fixing mechanism 120 is located on the minor axis body 110.
Particularly, vane rotor axial fixing mechanism 120 comprises that baffle plate 121 is fixed on the minor axis body 110 for the baffle plate 121 that axially blocks vane rotor 2 with for the nut 122 that axially presses vane rotor 2, and nut 122 is threaded with minor axis body 110.
One end of minor axis body 110 is baffle plates 121, and vane rotor 2 is installed on the minor axis body 110 by keyway, and then the nut 122 by the other end compresses, and prevents the generation of axial motion.The two ends frame of minor axis body 110 is finished the dynamic balance of impeller test on dynamic balancing machine.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a minor axis that is used for the vane rotor experiment of dynamic balancing is characterized in that, comprise minor axis body and vane rotor axial fixing mechanism, described vane rotor axial fixing mechanism is located on the described minor axis body.
2. a kind of minor axis for the vane rotor experiment of dynamic balancing according to claim 1, it is characterized in that, described vane rotor axial fixing mechanism comprises for the baffle plate that axially blocks described vane rotor with for the nut that axially presses described vane rotor, described baffle plate is fixed on the described minor axis body, and described nut is threaded with described minor axis body.
