Specific embodiment
The utility model is further described below with reference to embodiment.
It is as shown in Figure 1 dynamic dispenser 2 comprising if longer 21 and of primary blades of upper ring plate, lower Circular Plate, dry plate
If the shorter back blades 22 of dry plate (does not indicate upper ring plate and lower Circular Plate) in figure, primary blades 21 and back blades 22 are respectively provided with
Between upper ring plate and lower Circular Plate, primary blades 21 and back blades 22 are by circumferencial direction successively alternately uniformly arrangement, primary blades
21 and the outermost end of back blades 22 be located on same circumference 23.
As shown in Figures 2 and 3 it is the dynamic dispenser primary blades degree of impairment detection instrument 1 of the present embodiment, is equipped with arc
The diameter of shape bar 12, the inner arc surface 13 of curved rod 12 is equal with the diameter of circumference 23 where the outermost end of primary blades 21, arc
The inner arc surface 13 of shape bar is fixed with measuring rod 18 and fixture block 19 as benchmark arc surface on inner arc surface 13, is surveying
The end face of the separate curved rod 12 of gauge rod 18 is equipped with the first mark post 14 extended forward, is equipped in the front end face of the first mark post 14
The second mark post 15 extended forward, measuring rod 18, the first mark post 14 and the total length after being added of the second mark post 15 and primary blades 21
Equal length, in this way, can by the relationship compared between primary blades 21 and measuring rod 18, the first mark post 14 and the second mark post 15
It is fast and accurate to judge 21 degree of impairment of primary blades.The outer end of spacing and primary blades 21 between fixture block 19 and measuring rod 18
Thickness is corresponding.The length of first mark post 14 and the second mark post 15 is to be used to judge that primary blades to be eroded according to what is recorded in producer's handbook
Depending on the size of situation.
When detecting using detection instrument 1, measuring rod 18 is inserted into the main lobe that need to be detected from the outer rim side of dynamic dispenser 2
In gap between piece 21 and adjacent back blades 22, the inner arc surface 13 of curved rod 12 is resisted against the outer end of primary blades, measurement

With the regulation of producer's handbook and it is different.
Sometimes it can remain some solder on the welding edge of 21 two sides of primary blades, cause measuring rod 18 can not be with primary blades
21 fittings completely.In order to solve the problems, such as to be bonded completely, the cross section of the measuring rod 18 of the present embodiment is set as rectangular, so that
Measuring rod 18 can be preferably flattened in primary blades 21, be equipped with chamfering in the side for the plane of measuring rod 18 being bonded with primary blades
(chamfering is not shown in the figure), chamfering can make measuring rod avoid the solder for remaining in primary blades side.
It is covered with orchil on the side of the first mark post 14, to make warning alert effect, the present embodiment is in the first mark
Orchil is covered on the first section 17 formed on bar.
In order to it is more preferable, more easily use detection instrument, the present embodiment is equipped with handle 11 on the exterior arc surface of curved rod,
Worker can preferably use detection instrument by holding handle 11.On handle 11, frosted processing can be also done, to increase friction
Power.
The plane towards measuring rod 18 of the plane and fixture block 19 towards fixture block 19 of the measuring rod 18 of the present embodiment is mutual
In parallel.
In order to be more suitable for use in practice, it is preferred that the radius of the inner arc surface 13 of curved rod 12 is 176.801mm,
The length of measuring rod 18 is 77.530mm, and the integral thickness of detection instrument 1 is 7.25mm, the height and measuring rod of the first mark post 14
18 height differs 0.5mm, and the height of the second mark post 15 differs 0.5mm, the outer circle of curved rod 12 with the height of the first mark post 14
The radius of cambered surface is 186.801mm, and the chamfering of 18 side of measuring rod is 0.5mm chamfering.Measuring rod 18 with inner arc surface 13
The connection with the close measuring rod 18 of the junction of inner arc surface 13 on the connection side and fixture block 19 of the close fixture block 19 of junction
The linear distance on side is 13.010mm, i.e., the upper junction plate with the junction of inner arc surface 13 of measuring rod 18 as shown in Figure 3
