The working principle and the advantages of the invention are as follows: when the vortex ring leakage detection device for the electric vortex dynamometer is used, the working process is as follows:
as shown in fig. 1, under a stable test condition, an eddy ring to be detected is placed on the detection table 2, the positioning rod 4 plays a role in positioning so as to quickly and accurately align the port of the eddy ring with the hollow plug 13 and the solid plug 14, so as to improve the detection efficiency, then the hydraulic cylinder 7 is started to work, so that the hydraulic cylinder 7 drives the lifting plate 6 to move down, the hollow plug 13 and the solid plug 14 respectively plug the port of the eddy ring, and at this time, the hydraulic cylinder 7 is stopped and kept.
The motor 8 is started to work, the motor 8 drives the second conical roller 18 to rotate through the speed reducer 9, so that the second conical roller 18 drives the first conical roller 17 to rotate through the driving roller 39, the first conical roller 17 drives the air pump 10 to work, the air pump 10 conveys air into the hollow pressure rod 11 through the air pipe 21, air is conveyed into the vortex ring, and whether leaks exist in the vortex ring is detected, wherein the one-way valve 22 plays a role of preventing air leakage in the vortex ring, as shown in fig. 3, air pressure in the first sliding cylinder 20 and the second sliding cylinder 27 is synchronously increased along with increase of air pressure in the vortex ring, so that the piston plate 29 moves upwards in the second sliding cylinder 27 and compresses the second spring 28, the second spring 28 obtains restoring force, the rack 26 of the piston plate 29 ascends synchronously, the rack 26 drives the screw rod 42 to rotate through the toothed column 41 as shown in fig. 2, so that the screw rod 42 drives the rotating disc 40 and the driving roller 39 through the threads, the transmission ratio of the first conical roller 17 and the second conical roller 18 is reduced, the speed of conveying the air to the vortex ring is reduced, the air conveying speed of the vortex ring is gradually reduced, and damage to the vortex ring is prevented.
When the piston plate 29 is in abutting contact with the limiting rod 37, the air inflation is finished, the motor 8 is turned off, the buckling grooves 35 in the piston plate 29 correspond to the wedge-shaped ends of the locking rods 31, the locking rods 31 are inserted into the buckling grooves 35 under the action of the springs III 32, the position of the piston plate 29 is kept still, hardness of a detection result under the action of restoring force of the springs II 28 is avoided, and therefore the detection accuracy is guaranteed.
As described above, during the inflation process, the air pressure in the first slide cylinder 20 is gradually increased, so that the plunger 25 moves to the left in fig. 3 and compresses the first spring 24, so that the first spring 24 obtains a restoring force, and the hydraulic oil moves into the tubule 19 due to the left movement of the plunger 25, so that the floating plug 34 moves up in the tubule 19, after the inflation is finished, the height of the floating plug 34 in the tubule 19 is recorded, if no leak exists on the wall of the vortex ring, the air pressure in the vortex ring is unchanged, so that the height position of the floating plug 34 does not change, if a leak exists on the wall of the vortex ring, air leaks at the same time of inflation, so that the inflation time length is increased, and after the inflation is finished, the air pressure in the vortex ring is gradually reduced due to the air leakage, because the tubule 19 with a small inner diameter is used, the plunger 25 can slightly move in the first slide cylinder 20 due to the small air pressure change, so that the volume of the same amount of hydraulic oil in the slide cylinder 20 is slightly changed, and the change of the cross section volume is in a state of the volume is greatly changed in a state of the height of the tubule 19, so that the small air pressure change can be greatly increased, and the detection efficiency can be greatly improved, and the detection of the leakage of the hydraulic oil can be greatly increased, thereby increasing the detection efficiency can be greatly increased.
After the test is finished, the hydraulic cylinder 7 is started to drive the lifting plate 6 to move upwards and reset, so that the hollow pressure rod 11 drives the hollow plug 13 to move upwards, the solid pressure rod 12 drives the solid plug 14 to move upwards, and the detected vortex ring is taken down after the hollow plug 13, the solid plug 14 and two ports of the vortex ring are separated.
As described above, after the hollow plug 13 and the solid plug 14 are separated from the two ports of the swirl ring, the plunger 25 and the floating plug 34 are reset under the restoring force of the first spring 24 and the action of gravity, and in the process of moving up and resetting the lifting plate 6, the first sliding cylinder 20 synchronously drives the second sliding cylinder 27 and the wedge rod 30 thereon to move up, when the lower end of the suspension rod 15 abuts against and contacts with the wedge surface of the wedge rod 30, the wedge rod 30 drives the lock rod 31 to move left, and the third spring 32 is stretched to obtain a restoring force, so that the lock rod 31 is drawn out from the catching groove 35, at this time, the piston plate 29 drives the rack 26 to move down and reset under the action force of the second spring 28, so that the rack 26 drives the screw rod 42 to rotate reversely through the tooth column 41, as shown in fig. 2, so that the screw rod 42 drives the turntable 40 and the driving roller 39 to move left and reset through the screw thread transmission, so as to be used for next detection of the swirl ring.
