Specific embodiment
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited to following embodiments.
As shown in Figure 1, a kind of experimental provision for simulating eddy channel blade wear measurement, including experiment bucket 8, circulation pipe
Road 5, experiment motor 7 and experiment impeller 6.The top of the experiment bucket is opened wide and the bottom of experiment bucket is up big and down small funnel
Shape.
The experiment motor is fixed in experiment bucket by support construction.The support construction includes support plate 10 and support frame
11.The support plate is arranged horizontally in the top of experiment barrel cavity, and support frame is arranged outside experiment bucket and extends to experiment bucket
In connect with support plate.
The experiment impeller and experiment motor are arranged in the top and lower section of support plate.The experiment motor is fixed on
Support plate bottom surface, the shaft for testing motor pass through support plate straight up.The experiment motor is that the frequency conversion of adjustable revolving speed is dived under water
Motor, for meeting the requirement of different rotating speeds and experimental situation.
The experiment impeller includes that (as shown in Figure 6: blade is cambered surface for overhead gage 6.1, lower baffle plate 6.2 and several blades 6.3
Shape).The overhead gage with it is horizontally disposed above and below lower baffle plate.The blade be vertically fixed between overhead gage and lower baffle plate and
Radially arrange.The top vertical of the overhead gage is fixed with inlet tube 6.4, and the center of overhead gage is equipped with to be connected to inlet tube
Through-hole.The overhead gage can be used transparent material (such as organic glass) and be made, in order to Germicidal efficacy.The lower baffle plate passes through
The shaft of the connector (omitting in figure) of ring flange etc and experiment motor is fixed, and the top surface of lower baffle plate is matched equipped with several with blade
The fixing groove 6.21 (installation for facilitating blade) of conjunction, the shape of fixing groove is depending on blade shape.
The blade is fixed by fastener and overhead gage and lower baffle plate.The fastener can be bolt, set on overhead gage
There is the upper fixation hole 6.11 interted on several for bolt, several lower fixed holes interted for bolt are equipped in the fixing groove of lower baffle plate
