YJY12 series
Intrinsic safety on-line oil monitoring system for mine
YJY12The intrinsic safety type online oil monitor for mining is composed of oil quality data acquisition module (wear, viscosity, moisture, dielectric constant) Temperature, density, cleanliness sensor), equipment status acquisition module (pressure, vibration, flow), data processing module, object Network remote communication module. The system can realize coal detection by installing oil on-line monitoring in the recycling and return oil circuit of coal mine equipment Mining machinery equipment lubrication system, gearbox transmission system, hydraulic system and other oil aging state of real-time monitoring, coordination The internal oil aging model algorithm provides scientific monitoring data for oil life status and equipment operation status in real time to ensure The safe operation of the equipment and the design of various communication protocols provide powerful data support for the data visualization of intelligent coal mine.
