Problems solved by technology

However, the deposition device cannot realize the orderly deposition of wear particles, and the mixed use of permanent magnets and electromagnets increases the volume and complexity of the device
[0005] Therefore, the inventors found that in the deposition devices of online ferrography at the present stage, there is no device structure that can effectively realize the orderly deposition of wear particles and obtain the size distribution characteristics of wear particles

Embodiment 1

[0035] Embodiment 1 of the present disclosure discloses an electromagnetic device for orderly deposition of wear particles, which mainly includes:

[0036] Inner electromagnet—at least two sets of enamelled copper wires are wound on the inner electromagnet column, and the magnetic induction intensity is controlled by controlling the on and off of the current in the coil. There is a through hole in the center of the magnet for the placement of the flow channel;

[0037] Outer electromagnet—the outer electromagnet includes at least two sets of columns and the number of sets is the same as that of the inner electromagnet copper wires. The columns are wound with enamelled copper wires, and the magnetic induction intensity is controlled by controlling the on-off of the current in each set of coils;

[0038] Yoke—connects the magnetic circuit and transmits the magnetic field lines.

[0039] Flow Passages - The lubricating oil flows through the deposit areas through flow passages.

Abstract

The disclosure relates to an electromagnetic device for orderly deposition of wear particles, which belongs to the technical field of lubricating oil monitoring devices. The device includes an inner magnet, an outer magnet, a flow channel and a magnetic yoke; Multiple sets of coils are wound on the outer surface of the outer magnet; the outer magnet is composed of multi-section columns, which are arranged in a circle around the inner magnet and distributed around the inner magnet; each column is wound in the same direction; the outer magnet coil winding direction is the same as the inner magnet coil winding direction On the contrary; the yoke is used to fix the inner magnet and the outer magnet; the center of the yoke is provided with a center hole. The flow channel includes two parts: the upper and lower flow channels; the upper flow channel is provided with an oil outlet; the lower flow channel includes the oil inlet pipe and the surface deposition area; the oil inlet pipe is set in the through hole in the center of the inner magnet; the flow channel and the yoke are fixed inside and outside by buckling magnet. The device adjusts the magnetic induction intensity by changing the number of energized coil groups, and realizes the orderly separation of wear particles in the deposition area according to the size during the online monitoring process.

Description

technical field [0001] The disclosure belongs to the technical field of lubricating oil monitoring devices, in particular to an electromagnetic device and method for orderly deposition of wear particles. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Ferrography is a method of separating ferromagnetic wear particles from the lubrication system of mechanical equipment by using a high-gradient strong magnetic field, and then observing and analyzing them. Off-line ferrography (including direct-reading, analytical, and rotary) uses a permanent magnet with a specific structure to achieve orderly deposition of wear particles. The size, concentration, material and morphology information of wear particles can be obtained by densitometer, ferrographic microscope and scanning electron microscope. However, offline analysis is inseparable from manual sampl...
