Threshold self-learning oil filter pipeline leakage detection and protection device and method

Abstract

The invention discloses a threshold self-learning oil filter pipeline leakage detection and protection device and method. A first flow meter, a second flow meter, a first electric valve and a second electric valve are arranged on an inlet pipeline and an outlet pipeline of an oil filter; the first electric valve and the second electric valve are used for collecting the flow in the inlet pipeline and the outlet pipeline, the controller is used for comparing the flow with corresponding reference flow data to judge whether pipeline leakage exists or not, and if the pipeline leakage exists, the controller immediately gives an alarm, the oil filter is shut down, and the inlet electric valve and the outlet electric valve are closed at the same time. When leakage occurs, inlet and outlet electric valves of an oil filter and oil using equipment can be rapidly closed, the leakage amount of lubricating oil is reduced to the maximum extent, automatic protection control over leakage in the lubricating oil filtering process is achieved, manual closing is not needed, the safety of oil treatment work is improved, and the working intensity of field operators is reduced. The device can effectively prevent oil leakage, realizes unattended operation in the oil treatment process, and saves manpower.

Description

technical field [0001] The invention belongs to the technical field of oil filtration, in particular to a device and method for detecting and protecting pipeline leakage of an oil purifier with self-learning threshold. Background technique [0002] In the power industry, lubricating oil is usually used as the main medium for cooling, insulation and heat dissipation of oil-using equipment. In the process of use, lubricating oil inevitably contacts with metals, air and other substances, resulting in catalysis and deterioration, resulting in the particle size of oil products. , moisture, oxidation performance and other indicators exceed the standard. For the deteriorated oil, an oil filter is usually used to maintain the oil quality of the lubricating oil, so that the indicators of the oil meet the standard requirements. [0003] Some oil-using equipment has been equipped with oil purifiers at the beginning of design and production, but due to the relatively simple maintenance ...
