The cleanliness of the surface of the component has a very important influence on the reliability and durability of the component work. The pollutants on the surface of the parts are mostly solid particles such as chips, burrs, cast sand, welding slag and abrasives. These contaminants will accelerate the wear of the parts, block the orifice of the component and make the component lose its regulation function. The coal rock analysis will enter the spool gap and the valve core will be stuck, which will damage the inner surface of the cylinder and increase the leakage or reduce the output force. Small, it will damage the pump's oil distribution plate to burn or kill the pump. The emergence of these conditions ultimately leads to the loss or complete paralysis of system functions. Therefore, it is necessary to start from every detail of each link to prevent and reduce the generation of pollutants, so that the installed system can be safely and reliably operated.

The automatic cleanliness meter raises the automation, detection efficiency and detection accuracy of parts cleanliness detection to a new level. The fully automatic cleanliness analyzer collects contaminant particles on the filter paper in a fully automatic manner, and then quickly images the contaminated particles on the filter through a microscopic imaging system. The particle size can be analyzed and automatically distinguished by one-button operation. Particle type, particle distribution, in the assessment of rapid assessment of pollutant levels.
