The invention discloses an engine water circulation oil leakage detection system and a method for utilizing the system to perform oil leakage detection. A water circulation system water inlet and a water outlet of a to-be-detected engine are communicated with a water tank respectively through an engine water outlet pipe and an engine water inlet pipe of an engine test table frame. The system comprises a control system and an oil detection instrument. A water inlet and a water outlet of the oil detection instrument are respectively communicated with the engine water outlet pipe and the water tank through an oil detection instrument water inlet pipe and an oil detection instrument water outlet pipe, and an electromagnetic valve is arranged on the oil detection instrument water inlet pipe and used for controlling the oil detection instrument water inlet pipe to be opened and closed. The control system is respectively in controlled connection with the oil detection instrument, the electromagnetic valve and the to-be-detected engine. The engine water circulation oil leakage detection system is simple and reasonable in structure, the oil content of engine circulating water is detected timely accurately through the oil detection instrument, and the oil leakage conditions of the engine water circulation system are judged accurately.
Description
technical field [0001] The invention relates to the field of engines, in particular to an engine water circulation oil leakage detection system and an oil leakage detection method using the system. Background technique [0002] In the production process, the engine often needs to analyze and judge whether there are "three leaks" hidden dangers in the quality of the engine, so as to improve the failure check rate. At present, there are relatively mature methods for judging the "three leaks" on the outer surface of the engine by observing the leakage of the outer surface, and there is a more reliable method for judging the water leakage of the engine lubrication system by testing the quality of lubricating oil. At the same time, the automatic oil measuring instrument on the market The application technology is mature, but there is a lack of a detection system for detecting oil leakage faults in the engine water circulation system. Contents of the invention [0003] The pres...
