Dingan County is equipped with fixation holes, and the side of the fixation holes is installed with pedestal, and peace is fixed in the upper end outer surface of the pedestal
Equipped with buckle, and pedestal is fixedly connected with wheel disc, and the inner wall of the opening is installed with fitting cushion block.
Preferably, the shape of the wheel disc is circle, and the thickness of wheel disc is one centimetre.
Preferably, the shape of the wheel cap and opening is circle, and wheel cap is respectively positioned on the centre of wheel disc with opening.
Preferably, the shape of the fixation holes is round, and a diameter of 1 point 5 centimetre of fixation holes.
Preferably, the quantity of the damping spring is several groups.
Preferably, the shape of the fitting cushion block is arc, and is bonded the inner wall that cushion block is fitted in wheel cap.
Compared with prior art, the utility model has the advantages that：The tooth type centrifugal compressor impeller, by setting
The damping spring set just can effectively reduce the impeller in rotation when institute when the impeller is assembled and starts rotation
The vibrations of generation, it is ensured that impeller was stablized run, by the fixation holes of setting, when being used in different situations
When, just enable to multigroup impeller to be attached fixation by fixation holes and buckle, to just can be suitably used for different shapes
Condition, by the fitting cushion block of setting, when the impeller is assembled, by fitting cushion block so that the opening energy of the impeller
It is enough to be more bonded between attachment, the case where to avoid impeller from being slid when being used, whole equipment structure
Simply, easy to operate, vibrations can be reduced during use, and can be so that being attached fixation between multigroup impeller, also
It can make more to be bonded between impeller and attachment, it is more preferable relative to traditional approach.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-5, peace is fixed in the upper end outer surface of a kind of tooth type centrifugal compressor impeller, including wheel disc 1, wheel disc 1
Equipped with blade 2 and guide vane 3, and guide vane 3 is located at the side of blade 2, and the outer surface of wheel disc 1 is installed with wheel cap 4, wheel cap
4 upper end center position is installed with opening 5, and the inside of wheel disc 1 is installed with damping spring 6, in the upper end of wheel disc 1
Surface is installed with fixation holes 7, and the side of fixation holes 7 is installed with pedestal 8, and the upper end outer surface of pedestal 8 is fixed
Buckle 9 is installed, and pedestal 8 is fixedly connected with wheel disc 1, be open 5 inner wall be installed with fitting cushion block 10.
The shape of wheel disc 1 is circle, and the thickness of wheel disc 1 is one centimetre；Wheel cap 4 and the shape of opening 5 are circle, and
