Planar inductive wear particle monitoring device and measuring unit thereof

Abstract

The invention discloses a planar inductive wear particle monitoring device and a measuring unit thereof. The device comprises the measuring unit and an analysis module. The measuring unit comprises a planar inductor and a cavity, wherein taps at both ends of an inductance coil are connected with the analysis module; the cavity is used for liquid to be tested to flow through; and the inductance coil of the planar inductor is used as one part of the inner wall of the cavity. When the planar inductive wear particle monitoring device provided by the invention is applied to monitor wear particles in oil or other liquid to be tested, the cavity is used as a flow passage of the fluid to be tested; and due to the direction contact between the liquid to be tested and the inductance coil of the planar inductor, a theoretical space between the liquid to be tested and the inductance coil of the planar inductor is 0, so that the wear particles in the liquid to be tested can be passed through by more magnetic force lines and an insulated conductor has larger inductance change, and thus, the monitoring sensitivity is greatly improved. The planar 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 a planar inductive wear 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, timely and accurate grasp of the wear particles in the oil is of great significance to the safe and reliable operation of equipment and personal safety. [0003] For this reason, the prior art provides a planar 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 equipment to prevent The failure...
