Embodiment Construction

[0015] The marine ferrography instrument and its measurement and analysis method of the present invention will be described in detail below in conjunction with specific embodiments.

[0016] 1. The structure and specific working process of the marine ferrgraph

[0017] The composition of the marine ferrography instrument includes: spectrometry device 1, high-pixel camera 2, USB3, virtual instrument device 4, and notebook computer 5. The lubricating oil in the oil sample pool 6 in the spectrum making device 1 leaves abrasive grains on the glass substrate 8 through the micro pump 7, and the lubricating oil enters the waste oil pool 9. The high-pixel camera 2 takes high-definition images of the abrasive grains, and transmits the high-definition images to the notebook computer 5 through the virtual instrument device 4 . The image preprocessing software in the notebook computer 5 preprocesses the image to obtain five parameters including the area of ​​abrasive grains in the image,...

Abstract

The invention discloses a ferrograph for ships and a measurement and analysis method. The ferrograph comprises a ferrogram maker 1, a high pixel camera 2, a USB 3, a virtual instrument 4 and a notebook computer 5 and is characterized in that lubricating oil in an oil sample tank 6 in the ferrogram maker 1 goes through a micro-pump 7, abrasive particles stay on a glass substrate 8, the oil enters into a waste oil tank 9, high definition images of the abrasive particles are taken by the high pixel camera 2, the high definition images are transmitted into the notebook computer 5 by the virtual instrument 4, the images are processed by image pre-processing software in the notebook computer 5, an abrasive particle wear type is determined in a virtual interface of the notebook computer 5 by a grey clustering algorithm, a grey forecasting model (EGM(1,1)) is developed by a grey prediction algorithm and abrasive particle wear tendency is predicted. The ferrogram maker has a simple structure and is suitable for a complex electromagnetic environment of a ship cabin. Through use of the virtual instrument, the ferrograph for ships can be developed and upgraded at any time.

Description

Technical field: [0001] The invention relates to an analysis device for judging the wear condition of moving parts of a marine diesel engine according to the shape parameters of abrasive grains in lubricating oil of a lubricating system of a marine diesel engine, and belongs to the field of measuring instruments. Background technique: [0002] Since the ship sails in the ocean all the year round, the flow is scattered, and it is difficult to return to the port of registry for a long time. It is obviously not in line with the reality to use the analytical ferrography and rotary ferrography to establish a ferrography analysis room for marine diesel engines in the shipowner company. Publication number: 102494973A, Publication date: 2011-04-13, Invention name: On-line full-flow visual ferrography; Publication number: 101093191, Publication date: 2007-12-26, Invention name: Comprehensive detection system for oil pollutants Due to the narrowness of the ship's engine room, noise, v...
