Same working condition.
Rotating circular disk cavitation corrosion equipment, referred to as " rotating-table apparatus ", operation principle is：On disk away from axle center different distance at
The hydrophthalmia (hole) through disc thickness is provided with, it, will at hydrophthalmia rear portion when disk high speed rotation in the water body in being placed in water tank
Wake flow cavitation is generated, wherein the type vacuole of vacillating will crumble and fall in wake flow end, bubble collapse will generate cavitation erosion to test specimen, this
Sample can measure the relatively anti-cavitation corrosion ability of various materials for test or coating.
At present, there are some rotating circular disk cavitation corrosion equipment in Hydrodynamic cavitation laboratory, but all there is some shortcomings, for example：It is real
Test specimen is not easy to install with dismounting during testing, while test specimen position is influenced bigger by water flow fluctuation, and test specimen easily comes off；Equipment
The operating mode that can be simulated is relatively simple, little to the practical directive significance in scene；Experimental facilities is complicated, and operating process is cumbersome
Deng.
Therefore, equipment performance is stable, test specimen installing and dismounting is easy, Neng Goumo in a kind of simple in structure, experimentation of urgent need
Intend various working and rotating circular disk cavitation corrosion equipment time saving and energy saving, with strong applicability.
Utility model content
The utility model is intended to provide a kind of rotating circular disk cavitation corrosion equipment, and the rotating circular disk cavitation corrosion for solving at this stage is set
It is standby it is existing it is complicated, operating process is cumbersome, equipment performance is unstable in experimentation, test specimen it is not easy to install with dismounting,
The operating mode of simulation is single to wait series of problems.
Technical solution is used by the utility model solves its technical problem：
This rotating circular disk cavitation corrosion equipment is made of water tank, disk, shaft, inlet tube, iron ring, screw rod.It is opened up on disk
There are shaft through-hole, hydrophthalmia, screw vent, disk is used in shaft through hole with shaft and is keyed, the water on same disc radius
The size of eye differs, small hydrophthalmia on big disc radius, big hydrophthalmia size and small hydrophthalmia on small disc radius,
The size difference correspondent equal of big hydrophthalmia.Screw vent is equipped with internal thread and its size is the same.Water tank connects inlet tube, spiral shell
Bar passes through screw vent, and is connected through a screw thread iron ring at both ends.
The advantages of the utility model：
Hydrophthalmia size on same disc radius is different, the size of small hydrophthalmia, big hydrophthalmia on big disc radius
Size and the size difference correspondent equal of small hydrophthalmia, big hydrophthalmia on small disc radius, disk can be vertical with water tank in addition
Or it is horizontal positioned, the operating mode that can finally simulate is relatively more.Screw rod passes through screw vent, and connects iron ring, iron ring at its both ends
The degree for being screwed into screw rod is different, can place different size of test specimen, and test specimen is fixed, therefore test specimen is not present in experimentation
Situations such as coming off, test specimen installation is also easier with dismounting, simultaneously because the cavitation corrosion situation of screw rod both ends test specimen is different, it can be right
Than observation.Inlet tube can pass in and out working solution according to actual conditions.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is disk vertical view.
Fig. 3 is disk installation screw rod and the side view after iron ring.
Fig. 4 is screw rod and iron ring installation diagram.
In figure：Water tank 1, disk 2, shaft 3, inlet tube 4, shaft through-hole 5, iron ring 8, screw rod 9.
Specific embodiment
The utility model is further described below in conjunction with attached drawing：
This rotating circular disk cavitation corrosion equipment is made of water tank 1, disk 2, shaft 3, inlet tube 4, iron ring 8, screw rod 9.
Shaft through-hole 5, hydrophthalmia, screw vent are offered on disk 2；Disk 2 uses key with shaft 3 at shaft through-hole 5
Connection；The size of hydrophthalmia on same disc radius differs, the size of small hydrophthalmia, big hydrophthalmia on big disc radius
Distinguish correspondent equal with the size of hydrophthalmia small on small disc radius, big hydrophthalmia；Screw vent is equipped with internal thread and its size is big
It is small the same.
Water tank 1 connects inlet tube 4, for Inlet and outlet water or other working solutions；Shaft 3 connects motor, for providing power；Spiral shell
Bar 9 passes through screw vent, and iron ring 8 is connected through a screw thread at both ends.
Before equipment work, test specimen is placed in iron ring 8 first, then according to the actual size of test specimen, iron ring 8 is adjusted and is screwed into
The degree of screw rod 9, so as to achieve the purpose that fixed test specimen.Experimental needs can place test specimen at 9 both ends of screw rod,
Can only test specimen be placed in one end of screw rod 9；It is also possible to select one or several corresponding positions in screw vent
Connecting screw 9 places test specimen.
Water tank 1 after the completion of test specimen is placed, seals to (water tank 1 is detachable, and concrete structure is not belonging to the consideration of this utility model
Scope), water or other working solutions then are pumped into from inlet tube 4, hereafter starts motor, disk 2 is high with the rotation of shaft 3
Speed rotation.When high speed rotation (clockwise) in the water body in being placed in water tank 1 of disk 2, it is empty wake flow will to be generated at hydrophthalmia rear portion
Change, wherein the type vacuole of vacillating will crumble and fall in wake flow end, bubble collapse will generate cavitation erosion to test specimen, can thus determine
Property or use the relatively anti-cavitation corrosion ability of the various materials for test of correlation technique quantitative analysis.
Since the two sides of 8 both ends of screw rod, that is, disk 2 can place test specimen, the different works such as the hydraulic turbine or blade can be simulated
Make the cavitation corrosion situation in face；The size of hydrophthalmia on same disc radius differs, small hydrophthalmia, big hydrophthalmia on big disc radius
Size and the size difference correspondent equal of small hydrophthalmia, big hydrophthalmia on small disc radius, so there is four kinds of differences
The wake flow of intensity, i.e. four kinds of cavitation corrosion situations, have finally been significantly increased the applicability of the equipment.
When disk 2 is horizontal positioned as shown in Figure 1, then hydrophthalmia is in horizontal position, and disk 2 is in rotation process, together
Wake strength caused by one hydrophthalmia is equal always, so the active force suffered by test specimen is unchanged always.The position in disk 2 is by Fig. 1
Put and be rotated by 90 ° counterclockwise with water tank 1 when putting, then disk 2 is placed vertically, when disk 2 rotates, hydrophthalmia alternately through high water level,
Low water level, since high water level, low water level pressure size are different, so the active force suffered by test specimen is also at periodical change
Change.At this point, just increase the operating mode quantity that the equipment can be simulated.
Disk 2 is used with shaft 3 and is keyed, easy for assemble or unload；Iron ring 8 is used with screw rod 9 and is threadedly coupled, can be according to examination
The actual size of part and determine the degree being screwed into, so test specimen installing and dismounting is easy, and fixed, influenced it by water flow fluctuation
Position does not change, and equipment performance is stablized.
Such rotating circular disk cavitation corrosion device structure is simple, performance is stable in experimentation, test specimen installing and dismounting is easy, can
Various working is simulated, is had stronger with strong applicability.
