Based on the case of the oil-gas separator for engine parts, this article has found the key steps to improve the cleanliness level by extracting and analyzing the impurity particles on its surface, and has reached the limit requirements in the enterprise standard. The whole detection process is divided into two parts: particle extraction and analysis. The impurity particles on the surface of the sample are extracted and collected by pressure washing, and the weight and size of the impurity particles are analyzed using a high-precision balance and a microscope. The test results show that the weight of the impurity particles on the surface of the oil and gas separator is 1.68 mg, and the maximum particle size is 887.31μm, which does not meet the product standard requirements. Through the analysis of the actual situation of the case to find the reasons and formulate measures, the final weight of the impurity particles on the surface of the improved sample is 1.22mg, and the maximum particle size is 481.40μm, which effectively improves the cleanliness level of the oil and gas separator.
