The invention discloses a gearbox lubricating oil cleanliness detection pretreatment method based on an extinction method. The main design concept of the invention is as follows: a pre-prepared organic solvent and gearbox lubricating oil are mixed and stirred to obtain a to-be-detected and treated solution without small liquid particles; therefore, the influence of small liquid particles on the cleanliness detection result is eliminated. According to the invention, the extinction method can be suitable for the cleanliness detection of the gearbox lubricating oil again, so that the cleanliness detection of the gearbox lubricating oil can meet the requirement of accuracy, and can also meet the requirements of low-cost, low-threshold and high-efficiency mass production detection operation. In addition, the method is easy to operate, good in universality and applicability and capable of being expanded to other vehicles for oil use, i.e. cleanliness detection links of engine lubricating oil, hydraulic oil and the like.
Description
technical field [0001] The invention relates to the technical field of gearboxes, in particular to a method for detecting and preprocessing lubricating oil cleanliness of a gearbox based on an extinction method. Background technique [0002] The cleanliness of gearbox lubricating oil refers to the size and number distribution of solid particles in the oil (specific grade definition can refer to ISO 4406-1999), which is a very important indicator of gearbox lubricating oil. The cleanliness of the oil will affect the work of the gearbox hydraulic system, especially the solenoid valve. When the cleanliness is poor, it will affect the performance of the hydraulic system, and even cause functional failure in severe cases. [0003] In order to confirm whether the cleanliness of the gearbox lubricating oil meets the design requirements, corresponding testing is required. At present, there are two main methods for testing the cleanliness of gearbox lubricating oil, namely microscop...
