Inductive wear particle monitoring device and measuring unit thereof

Abstract

The invention discloses an inductive wear particle monitoring device and a measuring unit thereof. The device comprises a test coil and an analysis module. The measuring unit comprises an insulated conductor and a cavity, wherein taps at both ends of the insulated conductor are connected with the analysis module; the cavity is used for liquid to be tested to flow through; and the insulated conductor is fixed on the inner wall of the cavity in a spiral shape. When the inductive wear particle monitoring device provided by the invention is applied to monitor wear particles, the cavity is used as a flow passage of the fluid to be tested; and the liquid to be tested is directly in contact with the insulated conductor, so a theoretical space between the liquid to be tested and the insulated conductor is 0. Compared with the prior art, the wear particles in the liquid to be tested can be passed through by more magnetic force lines and the insulated conductor has larger inductance change, so that the monitoring sensitivity is greatly improved; the wear particles with the diameters of less than 50 micrometers in the liquid to be tested can be detected; and the inductive wear particle monitoring device and the measuring unit thereof have important significance in monitoring and diagnosing a fault of machine equipment.

Description

technical field [0001] The invention belongs to the technical field of oil monitoring, and in particular relates to an inductive abrasive grain monitoring device and a measuring unit thereof. Background technique [0002] During the operation of various machinery and equipment, wear particles suspended in the oil of the lubrication system will inevitably be produced. Large wear particles will cause serious damage to the equipment in a short time. Wear particles are an important information carrier of the internal wear state of the equipment. Therefore, it is of great significance to timely and accurately grasp the situation of wear particles in the oil for the fault monitoring and fault diagnosis of the equipment. [0003] For this reason, the prior art provides an inductive wear particle monitoring device, which monitors the wear particles in lubricating oil or other mechanical equipment oil, and plays a role in active preventive maintenance of the equipment, preventing the...
