Abstract

An embodiment of the present application provides a portable ferrography instrument, including a sensor assembly, a top cover, a first magnetic device, a movable image acquisition device, and an oil injection device; the top cover is located on the top of the sensor assembly, and is movable with the sensor assembly connected to form a cavity, the cavity is a test cavity, the first magnetic device is installed on the top cover, and is located in the test cavity; the oil injection device is used to inject oil samples into the test cavity; the lower part of the sensor assembly is installed There is a second magnetic device, the second magnetic device is used to adsorb ferromagnetic particles and paramagnetic particles in the oil sample flowing through the test surface of the sensor assembly; the image acquisition device is used to collect the ferromagnetic particles and / or particles adsorbed on the test surface or images of paramagnetic particles. The portable ferrograph of the present application has the advantages of short test time, simple operation process and portability, which is beneficial to popularization and application of the ferrgraph.

Description

technical field [0001] The present application relates to the technical field of particle detection, and in particular, the present application relates to a portable ferrography instrument. Background technique [0002] Ferrography is a device for testing mechanical wear. It separates the metal particles in the oil by magnetic force, and deposits them on a transparent substrate sequentially and non-overlappingly according to the size of the metal particles (that is, making spectrograms) , Observe under a microscope for qualitative analysis (referring to the monitoring and analysis of the surface morphology and composition of abrasive grains such as morphological characteristics, size and differences). Using the densitometer installed on the ferrographic microscope, the relative content of the large and small abrasive particles on the spectrogram can also be quantitatively analyzed, and the computer can also be used to process the image of the abrasive debris to obtain the re...
