Abstract
Disclosed is a detection method and a sensor for overloading gear oil dustiness, wherein the sensor is used to measure the overloading gear oil dustiness. The sensor is embedded with a speed reducer oil tank, an upper cavity wall of a casing is provided with oil guide holes, an inner core of the sensor is provided with a measuring oil bath, two sides of the measuring oil bath are provided with optical glass, the light beams emitted from a semiconductor sensor become parallel after passing through optical fiber and an optical fiber collimator, such that the light beams are shooted into the measuring oil bath to meet an embedded real time online measuring requirement, and the inner core of the sensor can be took out, such that the quartz glass baffle of the measuring oil cavity side wall may be cleaned without leakage of oil droplets. Based on optical principle, 850 nm is selected as the measuring wavelength, by means of an optical fiber measuring technology, the light is guided into the measuring oil cavity in parallel by the optical fiber collimator, light signals are transformed into electric signals by a silicon photocell after the optical fiber passes through the measuring oil cavity, and it is then capable of obtaining the dustiness degree of the gear oil by comparing with a dustiness degree comparison table.
Description
technical field [0001] The invention relates to a detection method and a sensor for the pollution degree of heavy-duty gear oil, which is a sensor mainly aimed at the pollution degree of solid particles of N320 heavy-duty gear oil. Background technique [0002] The traditional oil monitoring technology mainly adopts the analysis method of off-line sampling. This method not only requires expensive precision instruments, but also requires a long detection time. With the development of modern industry, the traditional oil monitoring technology is not conducive to the early diagnosis and prevention of mechanical system failures. In order to solve the problem of real-time on-site monitoring and diagnosis of mechanical equipment, the first problem is the development of online oil monitoring equipment, and the sensor is the core part of the online testing instrument, so the sensor technology is the first technology to be solved. On-line monitoring technology must include on-line ...
