12 requirements for metallographic microscope maintenance and maintenance work
As an optical instrument, the metallographic microscope should pay attention to the maintenance of the relevant details of the microscope, not only to protect the metallographic microscope, but also to be of great help to the stable work of the microscope. We all know that in production and scientific research, the microscope usually plays an important role. In the long-term working environment, the microscope may cause some small problems and cause the microscope to work abnormally. This requires us to do it carefully every day. Maintain the microscope and standardize the operation of the microscope.
1. The test room should have three defense conditions: shockproof (away from the source of shock), moisture-proof (use air conditioner, dryer), dust-proof (floor on the ground); power supply: 220V±10%, 50HZ; temperature: 0°C—40 °C.
2. When adjusting the focus, be careful not to let the objective lens touch the sample, so as not to scratch the objective lens.
3. Do not switch the objective lens when the center of the round hole of the stage gasket is far away from the center of the objective lens, so as not to scratch the objective lens.
4. Don't adjust the brightness suddenly, and don't be too bright, which will affect the service life of the bulb and also damage the eyesight.
5. For all (function) switching, the action should be light and in place.
6. When shutting down, adjust the brightness to the minimum.
7. Non-professionals should not adjust the lighting system (filament position lamp), so as not to affect the image quality.
8. Pay attention to high temperature when replacing the halogen lamp to avoid burns; be careful not to directly touch the glass body of the halogen lamp with your hands.
9. When the machine is not in use, adjust the objective lens to the lowest state through the focusing mechanism.
10. When the machine is turned off and not in use, do not cover the dust cover immediately, and cover it after it cools down. Pay attention to fire prevention.
11. Optical components that are not frequently used are placed in a drying dish.
12. Non-professionals should not try to wipe the objective lens and other optical components. The eyepiece can be wiped with a cotton swab dipped in a 3:7 ratio (absolute alcohol: ether) mixed liquid and wiped dry. Do not use other liquids to avoid damage to the eyepiece.
The maintenance work of the microscope needs to pay attention to the above 12 requirements, which is of great help to the maintenance of the microscope, effectively prolonging the working life of the microscope, saving costs and improving work efficiency.
