Introduction to the maintenance of the metallographic microscope stage and the storage of the microscope
According to usage requirements, the stage of the metallographic microscope does not require high mechanical strength, but the flatness of the stage and the verticality of the optical system axis are highly demanded. Otherwise, even if the performance of the objective lens is good, it will still affect the uniformity of the field of view clarity. To this end, it is necessary to avoid placing samples weighing more than 2 kilograms on the stage, to prevent the stage from being impacted, and not to use hammers or other objects to strike the table to prevent deformation and reduce instrument performance. Do not place heavy objects on the stage for a long time. When the microscope is not in use, remove the heavier samples to prevent damage to the lifting mechanism. The moving parts should be regularly lubricated with an appropriate amount of grease.
When using a microscope in cold seasons, sometimes you may feel that the movement of the stage is not flexible enough, which is caused by the cooling and solidification of lubricating oil or the increase in viscosity. At this time, you can drop gasoline into the four small holes on the stage, slowly dissolve the grease, and then remove the stage and slide plate, clean the oil stains with gasoline, and replace them with suitable lubricating oil to eliminate this fault.
Storage in use
The microscope should be kept by a dedicated person. The storage room should be chosen as a separate room that is relatively clean, well lit, and dry.
Metallographic microscope should be placed in the instrument cabinet and divided into several grids according to the variety* The lower floor is better for placing desiccants (such as silica gel, calcium chloride, charcoal, etc.), and there should be ventilation holes between each floor. The cabinet should be at least 0.5 meters away from the wall and 0.2 meters away from the ground. On the cabinet should
Hanging a registration form for storing instruments. Large and medium-sized metallographic microscopes should be placed on dedicated tables, tightly covered with glass, and filled with moisture absorbing agents.
Before storage, wipe and apply a small amount of rust proof oil to areas that have been repainted or oxidized.
Microscopes should not be stored in packaging boxes (transport boxes) for a long time (more than one month).
Due to climate change, it is necessary to regularly inspect, wipe, and ventilate, and take timely measures if problems are found.
