This utility model relates to the field of oil leakage detection technology, and in particular to an oil leakage detection device for a lubricating oil air-cooled radiator
filter element. It includes a
filter element body installed on the circulating oil
pipe of the radiator body, an
oil pump for controlling the circulation of the circulating oil
pipe on the circulating oil
pipe, a collection cylinder located outside the
filter element body, at least two proximity switches cooperating with a sensing element, and a controller. The upper end of the collection cylinder is open for collecting leaked oil from the filter element body. A
buoyancy rod is slidably connected inside the collection cylinder via a connecting pipe, and a
buoyancy ball is connected to the lower end of the
buoyancy rod. This utility model utilizes the buoyancy of the buoyancy ball to drive the sensing element to contact the proximity switch at the corresponding position, thereby realizing a multi-position detection and graded early warning mechanism. This avoids misoperation or overreaction caused by single threshold detection, provides operators with more reasonable
response time and decision-making basis, and reduces the
workload of on-site personnel inspection.
