Oil pollution levels can quantitatively reflect the degree of oil pollution and it is an important theoretical basis of oil pollution control. According to statistics, 70%-85% failure of the hydraulic system is caused by oil pollution. Therefore, the detection of oil pollution level has great significance in improving the reliability and extending the service life
