Part cleanliness detection device and detection method

Abstract

The invention relates to a part cleanliness detection device and detection method. The device comprises an electromagnet, a test solution storage container, a driving motor, a paddle, a tray, an electronic balance, a test solution buffer bottle, a filter membrane, a recovery bottle and a vacuum pump, wherein the test solution storage container is made of an iron material which can be adsorbed by the electromagnet, the driving motor is positioned above the test solution storage container, an output shaft of the driving motor extends into the test solution storage container, and the paddle is fixed on the output shaft of the driving motor; an electric heating pipe is arranged at the bottom of the tray; the electromagnet wraps the outer wall of the test solution storage container; the outputend of the lower part of the test solution storage container is connected with the input end of the upper part of the test solution buffer bottle through a valve; an opening is arranged in the test solution buffer bottle; the output end of the lower part of the test solution buffer bottle is connected with the recovery bottle through the filter membrane and another valve; the output end of the upper part of the recovery bottle is connected with the vacuum pump through an air pipe. According to the device, separation of iron impurities and non-iron impurities is achieved, the impurities can beroughly detected through the method, and the detection speed is increased.

Description

technical field [0001] The invention relates to the technical field of component quality detection, in particular to a component cleanliness detection device and detection method. Background technique [0002] In the factory inspection of automobile engines and transmission components, the inspection of cleanliness is the most basic inspection item and an important indicator to measure the quality of parts. Impurities adhering to parts may cause equipment failure, failure, and loss of control, and the tolerance of key transmission parts also has high requirements. If there are more pollutants between moving parts, it will accelerate the wear of parts and cause the whole machine to be damaged. Life shortened or scrapped. The purpose of component cleanliness testing is to eliminate or minimize early product failures to keep the cleanliness of components within the range of their pollution tolerance, so as to ensure the reliability and service life of components.

Problems solved by technology

[0003] At present, microporous membrane filtration devices are generally used for cleanliness testing. Since impurities are filtered through a single-layer membrane, it is easy to cause clogging of the pores of the filter membrane, thereby greatly reducing the detection speed and detection accuracy; the impurities obtained by this method contain different types. If you want to find the reason for the unqualified cleanliness, you need to separate the impurities. The steps are cumbersome and the operation process is complicated.
