Description

technical field [0001] The invention belongs to the technical field of permanent magnet gradient magnetic field filtration, and relates to a high-gradient magnetic system for filtering magnetic particles in lubricating oil. Background technique [0002] As the main lubricating medium of mechanical equipment, lubricating oil plays the roles of lubrication, cooling and heat dissipation. Metal wear is inevitable during the operation of the equipment, and the metal particles in the lubricating oil will accelerate the deterioration of the oil, so it is necessary to install a magnetic filter in the oil circuit. Due to the small particle size and weak magnetic properties of the particles, the commonly used magnetic rod type magnetic filter cannot remove the weak magnetic particles in the lubricating oil. [0003] The magnetic particle separation technology using the gradient magnetic field technology has been used in the separation of metal ore dressing and industrial wastewater. ...
