Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of casting flaw detection, in particular to a wind power accessory flaw detection system and method. BACKGROUND

[0002] The wind power accessory refers to a pure aluminum or aluminum alloy device obtained by casting, which is generally obtained by pouring heated aluminum or aluminum alloy into a mold cavity in the form of liquid aluminum or aluminum alloy, and is usually referred to as an aluminum die casting part.

[0003] Chinese patent application No. 201310661181.8 discloses an aluminum alloy impeller integral flaw detection method. According to the flaw detection method, the aluminum alloy impeller to be detected is placed in a container containing a solution. Since the solution has the same attenuation rate of X-ray as the aluminum alloy impeller, when the bottom plate is arranged at the bottom of the container and the container is irradiated with X-rays and imaged on the bottom plate, the image on the bottom plate can truly reflect whether the aluminum alloy impeller has pores, porosity, cracks, impurities and other defects.

During flaw detection, the valve cover is placed in the solution. Since the mounting holes a and the mounting holes b have small diameters, the solution cannot completely enter the mounting holes a and the mounting holes b, and air is left in the mounting holes a and the mounting holes b, which leads to inaccurate flaw detection of the valve cover.
