Description

Technical Field

[0001] This utility model relates to the field of spectrum preparation technology, and in particular to a spectrum preparation device for a dual-rotation ferrography instrument. Background Technology

[0002] The dual-rotation ferrograph is a novel oil analysis instrument for equipment operation. It utilizes a high-intensity gradient magnetic field to deposit ferromagnetic and paramagnetic particles generated by wear in the equipment's lubricating oil (or other liquid media) onto a glass substrate (ferrograph), arranging them according to the magnetic force distribution to form a ferrograph. During the abrasive deposition process, lubricating oil (or other liquid media) containing wear particles and other impurities drips onto the center of rotation of the ferrograph, which rotates along with the magnetic field. At this point, the ferromagnetic and paramagnetic abrasive particles are simultaneously subjected to gravity, centrifugal force, magnetic force, and internal friction of the lubricating oil (or other liquid media), depositing into a ferrograph within the working magnetic field region. Other impurities are ejected from the ferrograph under centrifugal force, essentially eliminating the deposition of impurity particles on the ferrograph and significantly reducing their interference with qualitative and quantitative ferrograph observation and analysis. The dual-rotation design and rapid magnetic head replacement greatly improve ferrograph preparation efficiency and tolerance to various contaminated oil samples. Therefore, the dual-rotation ferrograph is particularly suitable for qualitative and quantitative ferrograph analysis of severely contaminated oils. After the spectra are formed, a ferrography microscope is used to observe the size, shape, color, surface texture, etc. of the wear debris on the spectra, identify the wear type, and count the number of wear particles, thereby obtaining the technology of equipment wear conditions. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a spectral preparation device for a dual-rotation ferrography instrument. Impurities are thrown off the spectral slide under the action of centrifugal force, which basically eliminates the phenomenon of impurity particles depositing on the spectral slide, greatly reducing their interference with qualitative ferrography observation and quantitative ferrography analysis. The dual-rotation and quick-change magnetic head design greatly improves the spectral preparation efficiency and tolerance to various contaminated oil samples. During spectral preparation, the oil sample is dropped at the center of rotation of the substrate to ensure that the spectral image is evenly distributed circumferentially, and greatly reduces the harm of volatile solvents to the human body, ensuring the health of operators and facilitating the safe use of the instrument. The microcomputer-controlled stepper motor is directly connected to the main shaft, which is supported by two bearings, resulting in smooth rotation, low noise, and good stability, avoiding the impact of the instrument on the surrounding environment.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model discloses a spectrometer preparation device for a dual-rotation ferrography instrument, comprising a magnetic field stage 15. A first shock-absorbing leg 12 is fixedly connected to the lower surface of the magnetic field stage 15, located at the four corners of the magnetic field stage 15. A mounting frame 11 is fixedly connected to the upper surface of the magnetic field stage 15 via a mounting vertical rod 6. A limiting sleeve hole 7 is provided inside the mounting frame 11, and a quantitative pipette 1 is fitted inside the limiting sleeve hole 7. An oil sample 2 is placed inside the quantitative pipette 1. The front surface of the magnetic field stage 15 is fixedly connected to... There is an operating table 10, and a display screen 8 is installed on the upper end of the operating table 10. The display screen 8 is tilted at a 45-degree angle. The lower surface of the operating table 10 is fixedly connected to a second shock-absorbing leg 9, which is located at the four corners of the operating table 10. The upper surface of the magnetic field platform 15 is fixedly connected to an oil collecting cylinder 13. The upper end of the oil collecting cylinder 13 is fixedly connected to a positioning funnel 14. The lower end of the positioning funnel 14 is fixedly connected to a magnetic head 4, which is located inside the magnetic field platform 15. The upper surface of the magnetic head 4 is provided with a glass substrate 3.

[0023] Reference Figure 2 Stepper motor 5 is fixedly connected inside the magnetic field stage 15, and the output end of stepper motor 5 is fixedly connected to magnetic head 4.

[0024] Specifically, the magnetic field stage 15 is the core part for preparing the spectrum. The upper end of the magnetic field stage 15 has 1-2 concentric annular non-ferromagnetic gaps, which allow abrasive particles to be deposited in this gap area in a certain pattern. During operation, several drops of anhydrous ethanol are first placed on the magnetic head 4, and then the glass substrate 3 is placed on it. The glass substrate 3 is then wetted and fixed at the end of the magnetic field by anhydrous ethanol. The stepper motor 5 with microcomputer speed regulation is directly connected to the main shaft. After the residual oil is thrown out along the glass substrate 3, it is collected through the cylinder wall and enters the oil collection cylinder 13. During spectrum preparation, the oil sample 2 is dropped at the center of rotation of the glass substrate 3 to ensure that the spectrum is evenly distributed along the circumference.

[0025] Working principle: The dual-rotation ferrometer uses a permanent magnet, pole shoes and magnetic yoke to form a closed magnetic circuit. The working magnetic field is the 1-2 annular air gaps (narrow slits of about 0.5 mm) on the pole shoes. The magnetic field lines at the working position are parallel to the glass substrate 3. When lubricating oil containing ferromagnetic impurities flows into the glass substrate 3, the ferromagnetic material is retained on the glass substrate 3 under the action of the magnetic field force and is arranged along the direction of the magnetic field lines.

[0026] During the preparation of the spectrum, oil sample 2 is transported by a quantitative pipette 1 to a glass substrate 3 fixed on the upper end face of the magnetic head 4. The magnetic head 4 and the glass substrate 3 are rotated by a stepper motor 5. Due to centrifugal force, oil sample 2 flows outward along the plate. Ferromagnetic and paramagnetic abrasive particles in oil sample 2 are deposited on the glass substrate 3 according to the magnetic force distribution under the action of magnetic force, centrifugal force, liquid viscous resistance and gravity. The residual oil is thrown out from the edge of the glass substrate 3, collected and drained into the oil storage cup. After the glass substrate 3 is cleaned, fixed and dried, the ferrograph is prepared.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
