Atomization penetrating flaw detection device

Abstract

The invention discloses an atomization penetrating flaw detection device which comprises a penetrating groove, a penetrating fluid supply device and a waste gas exhaust device. The penetrating fluid supply device and the waste gas exhaust device are connected onto the penetrating groove. The atomization penetrating flaw detection device is characterized in that the penetrating groove is provided with a groove and an openable cover; the penetrating fluid supply device comprises a mist spray tank, a mist spray valve and a bidirectional fan, a penetrating fluid atomization spray nozzle is arranged in the mist spray tank, and the mist spray tank is communicated with the penetrating groove via the mist spray valve; the waste gas exhaust device comprises an exhaust valve, a waste gas filter tankand an exhaust fan, and the penetrating groove is communicated with the waste gas filter tank via the exhaust valve. The atomization penetrating flaw detection device has the advantages that the usage of penetrating fluid can be reduced to a great extent; the penetrating fluid penetrates the atomization penetrating flaw detection device in the form of mist and can be prevented from remaining in inner cavities, accordingly, workload on follow-up water treatment equipment can be relieved, and penetrating procedures are convenient to automatically control.

Description

technical field [0001] The invention relates to a device for flaw detection of parts, in particular to a device using a penetrating flaw detection method. Background technique [0002] Penetration testing is a non-destructive testing method that uses wetting and capillary phenomena to inspect material surface defects. The penetrant wets the surface of the part and penetrates into the surface defect under capillary action, so that the surface near the defect is different from other positions, and the detection of material defects is realized. The process of penetrant flaw detection can be divided into steps such as penetration, cleaning, imaging, and observation. Penetration methods generally include dipping, brushing and spraying. [0003] Among them, the dipping method is to immerse the workpiece directly in the prepared permeate tank, which is widely used because of its simple equipment, small investment and good permeation effect. However, with this method, the amount ...

Problems solved by technology

However, with this method, the amount of permeate used is large, and parts transfer personnel are required, which makes it difficult to realize automatic operation; at the same time, for parts with inner cavities, the inner surface does not need to be inspected and even the permeate is not easy to discharge, which reduces the cost of infiltration. Liquid, and form a huge load on the post-cleaning treatment

The spraying method is usually used for the detection of the surface of large-scale equipment. The penetrating liquid is directly sprayed on the inspected part of the workpiece. It is required to be used in an open environment or a well-ventilated place. In order to ensure that the surface of the inspected part is wet, manual observation is required. , the processing workload is large, and the processing effect has a greater relationship with the experience of the workers
