Problems solved by technology

Under normal circumstances, artificially proportioned magnetic suspension is used. During the use of magnetic suspension, the magnetic powder in water or kerosene will settle and agglomerate due to factors such as gravity, so that the concentration will gradually decrease. This is an irreversible process. Settling or agglomeration After re-stirring and diluting the magnetic powder, it is also difficult to achieve uniform distribution

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] refer to figure 1 As shown, a magnetic particle flaw detection magnetic suspension containing device includes a tooling box 4 for holding the magnetic suspension. The tooling box 4 is provided with a liquid suction pump 1, and the liquid suction pump 1 is electrically connected to The corresponding power supply is used to extract the magnetic suspension in the tooling box body 4. In the tooling box body 4 and at the periphery of the suction pump 1, several stirring air pipes 3 are arranged. One end of the stirring air pipe 3 Immerse and communicate with the magnetic suspension, and the other end is connected to the gas source through the corresponding pipeline and air valve, which is used to stir and turn the magnetic suspension with compressed gas.

[0020] The bottom of the liquid suction pump 1 is provided with a stirring ...

Abstract

The invention relates to a magnetic powder flaw detection magnetic suspension containing device which comprises a tool box body used for containing magnetic suspension, a liquid pump is arranged in the tool box body, the liquid pump is electrically connected with a corresponding power supply and used for pumping the magnetic suspension in the tool box body, and a plurality of stirring air pipes are arranged in the tool box body and located on the periphery of the liquid pump. One end of the stirring air pipe is immersed and communicated with the magnetic suspension, and the other end of the stirring air pipe is communicated with an air source through a corresponding pipeline and an air valve and used for stirring and stirring the magnetic suspension through compressed air. Manual stirringis replaced, the magnetic suspension is stirred in real time through compressed gas, the concentration change of the magnetic suspension in the using process is avoided, operation is simple and easy,and the stirring strength is adjustable.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and detection, in particular to a magnetic suspension liquid holding device for magnetic particle flaw detection. Background technique [0002] In the magnetic particle flaw detection of ferromagnetic materials, after the parts are magnetized, due to defects such as cracks, holes, and uneven density distribution, the magnetic field lines on the surface and near the surface of the parts are locally distorted to generate a leakage field, and then the magnetic flux applied to the surface of the parts The magnetic powder is adsorbed and accumulated, and visible magnetic marks are produced under the light of fluorescent lamps, etc., and then defects such as cracks on parts can be detected. [0003] Water or kerosene is often used as a carrier in the process of magnetic particle flaw detection. A certain proportion of magnetic powder is added to water or kerosene to prepare a magnetic susp...
