Problems solved by technology
[0004] However, when the above-mentioned monitoring device is used, it is necessary to periodically remove the magnet base to detect the amount of particle adsorption, which is cumbersome and laborious to operate. Not only that, during the removal process, the oil in the oil chamber is easy to leak, polluting the surrounding environment, causing oil waste, and need to interrupt the equipment to cooperate with the interrupted operation, resulting in reduced productivity, and increased labor costs due to the need for manual disassembly

The invention discloses a metal wear ferromagnetic particle sensor. The metal wear ferromagnetic particle sensor comprises a detection probe, a magnet assembly and a demagnetization assembly, wherein the magnet assembly and the demagnetization assembly are arranged in the detection probe; the metal wear ferromagnetic particle sensor further comprises a signal processing control unit and a wiring terminal used for electrical connection; the magnet assembly is used for generating a forward magnetic field for adsorbing ferromagnetic particles, and the degaussing assembly is used for exciting a reverse magnetic field which temporarily counteracts the forward magnetic field; and a magnetic field detection device connected with the signal processing control unit is arranged in an overlapped area of the forward magnetic field and the reverse magnetic field. The metal wear ferromagnetic particle sensor generates the forward magnetic field for adsorbing ferromagnetic particles through the magnet assembly, the magnetic field detection device detects the change of the magnetic field, and after the adsorption of the ferromagnetic particles reaches a preset value, the demagnetization assembly excites a reverse magnetic field temporarily counteracting the forward magnetic field, so that the ferromagnetic particles lose adsorption force and automatically fall off, manual operation is not needed, the detection cost is reduced, oil leakage is avoided, continuous operation of mechanical equipment is guaranteed, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of lubricating oil detection, in particular to a metal wear ferromagnetic particle sensor. Background technique [0002] Lubricating oil is the "blood" of mechanical equipment, which runs through the entire life cycle of equipment operation. It plays an important role in sealing, lubricating, cooling and anti-corrosion in mechanical equipment. Monitoring lubricating oil can keep abreast of equipment status, reasonably arrange maintenance time, reduce the impact of downtime and regular maintenance on production, not only prolong the mean time between failures of equipment, but also improve productivity. [0003] The traditional off-line lubricating oil condition monitoring refers to the comprehensive analysis of lubricating oil samples using various physical and chemical techniques, which not only consumes a lot of manpower and material resources, but also cannot diagnose problems in time, so the monitoring o...
