Description

Technical Field

[0001] The present invention relates to the technical field of flaw detection of axial flow pumps, and particularly to a component flaw detection device for an axial flow pump. Background Art

[0002] An axial flow pump is a pump that relies on the force generated by the blades of a rotating impeller on the liquid to convey the liquid along the axial direction. The main component among them is the impeller. To ensure the stability of the axial flow pump, flaw detection needs to be carried out on the impeller therein so that the staff can timely understand the condition of the impeller. The traditional flaw detection method is to manually perform flaw detection on the impeller, which is time-consuming and laborious, and it is difficult to detect small scars.

[0003] Therefore, there have emerged an X-ray flaw detection automatic verification device disclosed in the invention patent with the publication number CN111982937B and a non-destructive flaw detection device for vehicle parts disclosed in the invention patent with the publication number CN117517332B, etc., to perform flaw detection on the impeller.

[0004] However, it is found in the use process that when using X-ray for flaw detection, although it is relatively accurate, the cost is high, and it has a certain impact on the health of the staff. When using coloring flaw detection, although the cost is low, it is difficult to detect the defects extending into the impeller. When using ultrasonic flaw detection, although it can detect the defects extending into the impeller and will not affect the health of the staff, but because most impellers are thin, it is not convenient for ultrasonic to accurately detect the defects in the thin impeller, resulting in poor practicability. Therefore, there is an urgent need for a component flaw detection device for an axial flow pump to improve the above problems. Summary of the Invention

[0056] Clamp the axial flow pump impeller through the fixture 5. Extend the first hydraulic cylinder 11 to cover the sealing cover 12 on the top of the base 4. Then drain water into the sealing cover 12 through the drainage mechanism. Turn on the ultrasonic generator 42 to clean the oil stains on the axial flow pump impeller. After the cleaning is completed, raise the sealing cover 12 to let the water flow into the sewage tank 43, and then drain the water in the sewage tank 43 through the sewage discharge valve 44. At the same time, move the first piston 14 upward to open the fifth electromagnetic control valve, so that water enters the second water delivery pipe 48. At the same time, the piston 46 extends and the third hydraulic cylinder 47 moves downward to drain the cleaning liquid in the storage barrel 45 into the second water delivery pipe 48, so that both water and the cleaning liquid enter the spray pipe 49, mix the cleaning liquid with water, and then spray it out through multiple groups of nozzles 50 to clean the inside of the sealing cover 12.

Then inject air into the sealing cover 12 through the booster pump 8 to create a high pressure inside the sealing cover 12 and maintain it for a period of time to make the water penetrate into the defects of the axial flow pump impeller. Then contract the second hydraulic cylinder 15 to make the first piston 14 slide downward to suck the water back into the water storage barrel 13. Then place dry ice in the crushing barrel 18 and threadedly install the sealing cover 19 on the top of the crushing barrel 18.

At the same time, compressed air passes through the rotary scraper 22 and enters the crushing barrel 18 to mix the compressed air with the crushed dry ice to form a mixed gas. Then contract the first cylinder 29 to make the first slider 28 slide on the first slide rail 27 to cover the first support cover 31 on the axial flow pump impeller.

Since the temperature of the axial flow pump impeller is different from the temperature of the water in its defects,Highlight the defect location and transmit the detection result to the processor 41. The processor 41 draws a three-dimensional structure diagram of the axial flow pump impeller, displays the temperature at each position in the three-dimensional structure diagram, and then transmits the three-dimensional structure diagram back to the computer used by the staff, thereby improving the practicality of the device.
