Maintenance of metallurgical microscope stage and storage of microscope
According to the requirements of use, the carrier stage of metallographic microscope, does not require high mechanical strength, but the straightness of the stage and the perpendicularity of the axis of the optical system requires high. Otherwise, even if the performance of the objective lens is good, it will affect the uniformity of the field of view clarity. For this reason, it should not be placed on the carrier stage weight more than 2 kg of specimens, to prevent the carrier stage to be impacted, not to mention the hammer or other objects to knock the table surface, in order to prevent the deformation of the table surface, reduce the performance of the instrument, do not place heavy objects on the carrier stage for a long period of time, microscope is not in use, that is, the weight of the specimen is to be taken away in order to prevent damage to the lifting mechanism, the activities of the part should be added on a regular basis with an appropriate amount of lubricating grease.
In the cold season to use the microscope, sometimes feel the moving of the carrier stage is not flexible enough, this is due to the lubricant cooling solidification or viscosity caused by the increase, at this time, you can drop gasoline into the four small holes on the surface of the carrier stage, and slowly dissolve the grease, and then take out the carrier stage and the sliding plate gear, with gasoline will be cleaned up, replaced with the appropriate lubricant, you can rule out this kind of failure.
Storage in the state of use
The microscope should be kept by the person in charge. Keeping room should choose a cleaner, well-lit and dry separate room.
Metallographic microscope is best placed in the instrument cabinet, according to the species into several compartments. The lowest layer of the best desiccant (such as silica gel, calcium chloride, charcoal, etc.), there should be ventilation holes between the layers, the cabinet from the wall in more than 0.5 metres, more than 0.2 metres from the ground. The cabinet should be
Hang a registration form for the custody of the instrument. Large and medium-sized metallurgical microscope should be placed on a special table, with a glass cover tightly, inside the moisture-absorbing agent.
It should be wiped before storage, and a small amount of antirust oil should be applied to the parts that have been depainted or oxidised.
The microscope should not be kept in the packing box (transport box) for a long time (more than one month).
According to the climate change, it needs to be checked, wiped and ventilated frequently, and timely measures should be taken when problems are found.
