In addition, the body 2 has a bearing 20 built in the center thereof. The bearing 20 and the rotary bar 3 are coupled to each other so that the sliding scale 4 coupled with the rotary bar 3 is not rotated, So that it is smoothly rotated in place with the bar 3.

The sliding scale 4 includes an upper horizontal ruler member 40 and a lower horizontal support member 42. The sliding scale bar 4 is inserted into the rotary bar 3 and is horizontally extended. One end of which is fixed by the fixing member 44 and the other end of which is connected to the rotary bar 3 by the engaging member 46, The distance between the center of the impeller 1 and the vane 12 can be measured by the impeller 40, so that the structure can be easily seen at a glance.

The horizontal and vertical support members 40 and 42 of the sliding scale 4 are connected to each other by the upper and lower portions of the conveying block 5, 42 are provided so as to be freely slidable and capable of measuring the distance from the center of the boss 10 of the impeller 1 to the end of the vane 12 and provided with a fixed knob 52 at one side The one-side protractor 50 is configured to be able to fix the position of the transfer block 5 at a required position and to measure the distance to each vane 12 while rotating around the rotary bar 3, So that the angle of the vane 12 with respect to the end of the vane 12 can be measured.

The measuring unit 6 is connected to one side of the transport block 5 and is provided with a measurement window 62 for measuring the scale of the protractor 50 from the outside, And a vane measuring scale 60 is provided on one side of the vane 12 so that measurement of the abrasion portion of the vane 12 can be performed.

In the case of the present invention as described above, the operation is performed as follows.

4, the body 2 is coupled to the center hole 10a formed in the boss 10 of the impeller 1 and the bearing 20 of the body 2 The sliding bar 4 and the measuring bar 6 are engaged with each other and the sliding bar 4 is moved upward from the top of the rotating bar 3 in a state where the sliding scale 4, The rotating bar 3 is inserted into the body 2 in a state where the engaging member 46 is engaged or the rotating bar 3, the sliding scale 4, the transport block 5 and the measurer 6 are engaged, Or in the state where the body 2, the rotary bar 3, the sliding scale 4, the transport block 5 and the measurer 6 are engaged with each other, And is engaged with the center hole 10a of the impeller 1 to perform preparatory work for measuring the impeller 1. [

Next, the transport block 5 is positioned by sliding the slide ruler 4 so as to match the position and distance with respect to the vane 12, and is brought into alignment with the position for measurement, The distance, the angle, and the like with respect to the abrasion portion of the vane 12 from the center of the impeller 1 can be measured after adjusting the angle of the vane 12.

After the position of the transport block 5 is temporarily fixed by the fixing knob 52 at the above measurement point, the slide ruler 4, the transport block 5, and the measurer 6 are moved around the rotary bar 3, The comparative measurement of the vanes 12 of the impeller 1 becomes possible.

Of course, after the measurement operation is completed, the body 2 may be separated from the impeller 1 and installed in the impeller 1 for another measurement, and another measurement operation may be performed.

Therefore, according to the present invention, it is possible to analyze the cause of the pump vibration by measuring and comparing the amount of wear of each vane 12 of the impeller 1, and it is possible to improve the reliability of maintenance for the customer, And it is possible to economically utilize the reduction of the maintenance manpower such as shortening of the maintenance manpower.
