Therefore, there is a need for an improvement over the prior art to address the deficiencies of the prior art.
The invention comprises the following steps:
the invention provides a cooling system of an overspeed test bed of a magnetic suspension fan impeller, which aims to solve the problems in the prior art.
The invention adopts the technical scheme that: the cooling system comprises a test bed, a host machine, a protection end cover, a guide rail bracket, guide rails, sliding blocks, air cylinder brackets, a first air cylinder, a blower, a butterfly valve and a single-acting air cylinder, wherein the host machine is fixed on the test bed; the first cylinder is fixedly connected between the two cylinder brackets, and a cylinder shaft of the first cylinder is fixedly connected with the protective end cover; the air outlet of the blower is communicated with the host through a butterfly valve, and the cylinder shaft of the single-acting cylinder is connected with the valve rod of the butterfly valve and controls the opening and closing of the butterfly valve.
Further, the protection end cover is provided with a balance pin, the cylinder bracket is provided with a pin hole, the diameter of the pin hole is larger than that of the balance pin, and the balance pin is arranged in the pin hole in a penetrating mode.
The invention has the following beneficial effects:
1) The invention adopts the blower to cool forcedly, reduces the cooling time and improves the cooling efficiency;
2) The invention has simple structure and convenient use, adopts the first cylinder to assemble and disassemble the protective end cover, and improves the working efficiency and the safety.
Description of the drawings:
fig. 1 is a rear three-dimensional view of the present invention.
Fig. 2 is a front three-dimensional view of the present invention.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the invention discloses a cooling system for a magnetic suspension fan impeller overspeed test bed, which comprises a test bed 11, a main machine 12, a protection end cover 13, a guide rail bracket 21, a guide rail 22, a sliding block 23, a cylinder bracket 31, a first cylinder 32, a blower 51, a butterfly valve 52 and a single-acting cylinder 53, wherein the main machine 12 is fixed on the test bed 11, and the protection end cover 13 covers the main machine 12. The guide rail brackets 21 are fixed on the test bed 11, the two guide rails 22 are mutually parallel and fixed on the guide rail brackets 21, the two sliding blocks 23 are connected on each guide rail 22 in a sliding way, the two cylinder brackets 31 are mutually parallel, the cylinder brackets 31 are perpendicular to the guide rails 22, and two ends of each cylinder bracket 31 are fixedly connected with one sliding block 23 on each guide rail 22. The first cylinder 32 is fixedly connected between the two cylinder brackets 31, and the cylinder shaft of the first cylinder 32 is fixedly connected with the protective end cover 13. The air outlet of the blower 51 is connected with one port of the butterfly valve 52 through a connecting pipe, the other port of the butterfly valve 52 is connected with the host 12 through a connecting pipe, the cylinder shaft of the single-acting cylinder 53 is connected with the valve rod of the butterfly valve 52, and the opening and closing of the butterfly valve 52 are controlled.
In order to ensure the stability of the movement of the protecting end cover 13, a balance pin 41 is arranged on the protecting end cover 13, a pin hole is arranged on the cylinder bracket 31, the diameter of the pin hole is larger than that of the balance pin 41, and the balance pin 41 is penetrated in the pin hole.
When the overspeed test stand performs overspeed test, the single-acting cylinder 53 is not pressurized, the butterfly valve 52 is closed, and the blower 51 is not operated. After the test is completed, the single-acting cylinder 53 is firstly pressurized to open the butterfly valve, the blower 51 starts to work after the valve of the butterfly valve 52 is opened, normal-temperature air is pumped in from the bottom of the main machine, and hot air is discharged from the upper part of the main machine 12.
During overspeed test, the impeller is firstly arranged in the overspeed test stand, the cylinder bracket 31 is moved to enable the protection end cover 13 and the host 12 to be in the same center, the first cylinder 32 is ventilated, and the protection end cover 13 is lowered and pressed on the host 12. After the test is completed, the first cylinder is depressurized, the protective end cover 13 is lifted, and the initial position is returned. Finally, the cylinder bracket 31 is removed, and the impeller is detached. The balance pin 41 prevents the protective end cap 13 from shaking too much during the ascent and descent.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
