A transmission test oil circulation filter system, device and method

Abstract

The invention discloses an oil circulating filtration system, device and method for a transmission test. The system comprises dirty oil tanks and a clean oil liquid storage tank. The dirty oil tanks communicate with the clean oil liquid storage tank through a multi-stage filtration device. The multi-stage filtration device is used for intercepting particles with the particle diameter being 5 micrometers or above in dirty oil. The clean oil liquid storage tank is connected with an oiling connector through an oiling pump. The oiling connector is used for being connected with an oiling fuse of a gearbox. The dirty oil tanks are connected with an oil drainage connector through an oil well pump. The oil drainage connector is used for being connected with an oil pumping hose of the gearbox. An oil outlet particle counter is connected to an oil pumping pipeline of the oil drainage connector in parallel. According to the oil circulating filtration system, device and method, oil product filtration precision and controllability of offline assembly cleanliness are guaranteed, and meanwhile, the technical requirements for use and maintenance convenience, low cost and the long period of filtration equipment are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of transmission testing, in particular to an oil circulation filtering system, device and method for transmission testing. 【Background technique】 [0002] The internal cleanliness of the transmission assembly is one of the important indicators for evaluating the quality of the assembly. If the cleanliness is poor and there are many magazine particles, it will directly affect the service life of the internal transmission parts. The cleanliness of the assembly is determined by many factors in the production process, especially in the test run of the transmission. Since the test oil is recycled, if the oil filtration accuracy is poorly controlled, it will lead to the accumulation of impurity particles in the oil. Therefore, the test run process often causes damage to the assembly. Secondary pollution. Secondly, traditional filtration equipment cannot monitor the cleanliness of the filtered test oil online, a...

AI Technical Summary

Problems solved by technology

The cleanliness of the assembly is determined by many factors in the production process, especially in the test run of the transmission. Since the test oil is recycled, if the oil filtration accuracy is poorly controlled, it will lead to the accumulation of impurity particles in the oil. Therefore, the test run process often causes damage to the assembly. Secondary pollution

Secondly, traditional filtration equipment cannot monitor the cleanliness of the filtered test oil online, and only rely on laboratory measurements or experience for maintenance, so it is difficult to control the operating status of the equipment and the level of oil filtration

In addition, the general transmission test run in the industry adopts the process of refueling→test run→draining oil. Due to the limited amount of oil in the test run, there are residual impurities in the assembly, and the cleanliness of the off-line assembly is difficult to meet the standard.

Finally, the unreasonable layout and filtration scheme of the filtration equipment often lead to problems such as difficult maintenance, high cost of use, and short maintenance cycle
