"The maintenance of the microscope"
1, regular maintenance
(1) If the indoor humidity moisture, optical lens, it is easy to mycophenolate Health, Health and fog. Once the Health sp lens, it is difficult to remove. As the lens of the microscope in-house cleaning inconvenience, the greater the danger to its wet. Mechanical parts damp, vulnerable to rust. In order to moisture, and stored microscope, in addition to the choice of drying room, the place should be kept away from the wall, off and away from the source of wetlands. Microscope should be placed inside a bag or 2 for desiccant silica gel. And always carry silicone baking. In his post-pink color change should be baked in a timely manner, and then continue to use baking.
(2) dust on the surface of optical components from falling into the dust, not only through the effects of light, but also by the optical amplification system will generate a lot of Wu Ban, to observe the impact. Dust, sand falling into the hands of some of the machinery, we will increase the wear and tear caused disruption campaign against much the same. It is therefore necessary to keep the microscope clean.
(3) anti-corrosion microscope and can not have the corrosive chemical reagents together. Such as sulfuric acid, hydrochloric acid, alkali and so on.
(4) thermal heat of the main purpose is to avoid Rezhanglengsu cause the lens to open with the plastic off.
2, the optical system clean
Usually on the part of the optical microscope of the surface with a clean sweep of the brush or rub with paper-that is, wipe clean lines. Ma Budiao there are lenses in the dirt, oil or finger printed, mycophenolate lens hygiene, Health and the fog out after the resumption of long-term use, they need to go through the use of clean again.
(1) scope of the eyepiece and clean condenser open to allow clean. As a result of the complex structure of the lens, when the assembly but also specialized equipment that can be corrected to restore the original precision, it is strictly forbidden apart to clean.
Eyepiece and the demolition of condenser, should pay attention to the following:
A, be careful.
b, demolition, to mark the components of the relative position (in the shell can make a mark on line), the relative order of the lens and back to prevent the re-made a mistake when.
C, operating environment should be kept clean and dry. Eyepiece demolition, as long as the spin from both ends of the lens up and down to two. Eyepiece field of view of the light bar can not move. Otherwise, the fuzzy boundary of the field will. Condenser is strictly prohibited further spin-opened after the break on the lens. Its lens is on oil, the factory after a good seal, then it would undermine the decomposition of the damage and seal performance.
2. Methods used to wipe clean or brush hair ball on the surface of the lens to remove dust. And then with a clean flannel from the lens center to the edge of the beginning for a one-way spiral movement. Cawan flannel for the first time in one place and then wipe, wipe up to date. If there is oil on the lens, such as fingerprints or dirt Cabu Diao, Panicum be available Guoshang cotton, dip a small amount of alcohol and ether mixture (80% alcohol, 20% ether) cleanse. If there is more or Meidian of Meiban not removed, can be attached after wetting cotton Zhanshui calcium carbonate powder (the content for more than 99%) to wipe. Clean, powder should be cleared away. Whether or not wipe lenses, lenses can be used on light reflection to observe the inspection. It should be noted that the former must wipe the dust In addition to the net. Otherwise, the dust of the sand will draw from Gouwen mirror. Are not allowed to use a towel, handkerchief, clothing, etc. to clean the lens. Mixture of alcohol ether can not be used too much in order to avoid the lens into the liquid adhesive so that the Department of degumming lens. The surface of the lens has a layer of purple light blue film, do not be mistaken for dirt wiped.
3, the mechanical part of the clean
Some of the paint surface can be used to clean cloth. But we can not use alcohol, organic solvents such as ethyl ether rub, so as not to paint stripping. If it does not paint some of the rust can be wiped cloth dipped gasoline. After re-wipe grease can be good protection.
■ rule out the possibility of mechanical failure
1, the rough part of the transfer rule out the possibility of failure
The failure of the main coarse redeployment is automatically down or landing and taking off at different elastic. The so-called auto-down means the tube, or arm-loading Taiwan in a stationary position, without regulation, in the role of the weight of its own, automatically falling slowly. The reason is that tube, the arm-and objects to Taiwan's own set of gravity than the static caused by friction. The solution is to increase the static friction so that it is greater than or tube-arm its own gravity.
Most tube Oblique for the binocular microscope and the transfer of rough body, the mirror when the arm down automatically, respectively, two-handed grip can be used to transfer crude hand round the inside of the pulley only his hands are tightening force in a clockwise direction, you can Stop the decline. If we do not ineffective, they should look for professionals to carry out repairs.
Tube down automatically, often in order to give the misleading impression is that the gear rack and with the rise of the song too. So on the rack in Canada under the pads. In this way, the tube down while stopped for the time being, but to make gear and rack in an abnormal state of the bite. The results of the campaign, making gear and rack are deformed. In particular, is not normally pad, the deformation of the rack is much heavier, resulting in a part of tighter bite, the bitten part of the song. As a result, this method should not be used.
In addition, the coordinating body for a long time due to the lack of rough, dry lubricants, landing and taking off at will feel uncomfortable, or even hear the mechanical sound of friction. At this time, can be removed cleansing mechanism, the oil re-assembly.
2, rule out the possibility of fine-tuning some of the fault
Fine-tuning some of the most common failure is a failure and death card. Fine-tuning some of the equipment installed in the interior of its mechanical parts small, compact, the microscope is the most complex and sophisticated. Fine-tuning parts of the fault should be professional and technical personnel to carry out repairs. Do not have enough grasp of the Do not indiscriminate demolition.
3, lens converters rule out the possibility of failure
The main objective of the converter failure is the failure of positioning device. Spring is the general orientation film damage (deformation, fracture, loss of elasticity, spring-chip fixed screw loose, etc.) caused by the replacement of the new films spring, we should not screw tightened up, this section should be "three (b) 2" First optical axis for correction. , And other co-axis, the screw tightened up again. If the inside-positioning of the converter should be under the rotating disk rotation of the bulk of the central screw, turn off disk in order to position the replacement of a spring-chip, optical correction method and the same front.
4, condenser-body movements rule out the possibility of failure
This is a major part of the fault is automatically down. Ruled out as follows:
(1) Straight microscope condenser's body movements as shown in Figure 10-3-2: 1.5. Celluloid washer 2. Gordonia 3 screws. Gear-eccentric set of 4-under. Tooth 6-under. Handwheel movements 7. Eyes nut
Adjustment, with his eyes with one hand in hand to insert round of nut wrench-side surface of the eyes of the nut, with one hand and insert the screwdriver on the other side of the big screw slot, the force can be tightened up to stop falling.
(2) oblique microscope condenser tube's body movements as shown in Figure 10-3-3:
Adjustment, the first driver to use the eyes in the middle of the screw nut 2 to 1 out of 2 circles, bearings and gasket 3 is in line with the snail 2 pressed, it will follow along from, and teeth from the end of 10-under. Then, with his eyes blindfolded nut wrench to adjust to a nut Block 5 precession. At the same time, another round of hand to hand, the test until a suitable elastic body movements, can stay at any position, only his eyes to stop the nut precession. Finally, in further into the spiral, so that the tooth contact bearing washer-under 10 on the line.
The reason why this can be adjusted troubleshooting because regulation of Block 5 in the hole is tapered. 4 conical sleeve in the axial a slot, as shown in Figure 10-3-4. When his eyes to a nut, precession, the cone will be set to the top, so that the cone-shaped set in advance, the smaller the slot, inside the hole shrink to 10-under-tooth folder closer, stepped up a gear rotation Frictional resistance, which automatically stop the decline.
