測繪儀器的保養和使用

1 設計儀器時注意防霧,儀器結構應加強密封性能,保證儀器在高溫或低溫情況下不降低密封性能,以防止因漏氣而引起的水性霧,設計人員應當充分注意選擇化學穩定性能好的光學玻璃和材料,為防霧打下良好的基礎。 1 design instrument attention to anti fog, the structure of the instrument should be strengthened to ensure the sealing performance, the instrument does not reduce the sealing performance under high temperature or low temperature, to prevent water fog caused by leakage, designers should fully pay attention to the choice of good chemical stability of the glass and optical materials, a good foundation for anti fog lay. 2 在制造和維修過程中注意整潔生產,裝配和維修的工房須清潔,并嚴格遵守操作規程,精心擦拭光學零件,嚴禁用手直接接觸和拿取光學零件,夾持光學零件的工具須進行脫脂處理,擦光學零件所用的輔件,如棉光、布塊、乙醇、乙醚、碘以及與光學零件接觸的有機墊片均須進行嚴格脫脂,控制含脂量,裝光學零件的器皿和盛乙醇、乙醚的瓶子,須經常清洗,保持清潔,這些都是減少油性霧的重要途徑。 2 in the manufacturing and maintenance process that clean production, assembly and maintenance of the workshop shall be clean, and strictly abide by the rules, carefully wiping optical components, non hand contact and taking optical components, optical parts clamping tools shall be degreased parts for wiping optical accessories, such as cotton light a piece of cloth, and ethanol, ethyl ether, iodine and contact with the optical parts of organic gaskets shall conduct strict degreasing, control the amount of fat, vessels and optical parts with ethanol and ether bottle, require regular cleaning, keep clean, these are less important way less oily mist. 3 減少儀器內部的水蒸氣,防止水蒸氣在玻璃表面上凝結,盡可能在干燥的條件下進行裝配或對裝配好的儀器進行干燥處理,如充干燥氮氣或空氣以及放置干燥劑。儀器在使用和庫存中,盡量控制使用環境和庫房的相對濕度在6%左右,對于外業儀器在使用中不好控制濕度,用后應放在通風、向陽、干燥的地方,在儀器箱內放入干燥劑,并注意密封和及時更換烘干硅膠干燥劑,在潮濕環境下,使用的內業儀器,如糾正儀、復照儀等,對于可取下來的鏡頭和精密的光學部件,用后及時取下來故人干燥缸內加以保護,并經常保持儀器清潔,減少結霧核心。 2.3.4 合理選擇和使用油脂,光學儀器上用的各種防塵脂、潤油油脂必須是揮發度極低和化學穩定性好的材料,在光學儀器的金屬零件上涂油脂時,首先要把零件清洗干凈,讓汽油揮發完后再涂油脂,并且要涂均勻而不能過多,距光學件10-15mm的范圍內,禁止涂潤滑油脂和防塵脂,防止油脂擴散引起油性霧。 3, reduce the water vapor inside the instrument, prevent condensation of water vapor on the surface of the glass, and assemble it as far as possible under dry conditions, or desiccation of the assembled instruments, such as drying nitrogen or air and placing desiccant. In the use of equipment and inventory, try to control the relative humidity of environment and warehouse in about 6%, the field instrument does not control the humidity good in use, after use should be placed in ventilated, dry, sunny place, in the instrument box with desiccant, and pay attention to the sealing and timely replacement of silica gel desiccant drying, in the wet environment, use the instrument within the industry, such as correcting instrument, camera, lens and it for precision optics, with time after taking down enemy drying cylinder to protect and keep equipment clean, reduce fogging core. 2.3.4 the reasonable selection and use of oil, optical instruments used in a variety of dust grease, lubricating oil grease must be very low volatility and good chemical stability of the material, metal parts in the optical instruments with grease, first of all to the parts clean, let the volatilization of gasoline after oil and grease, and spread evenly not too much, from the range of optical 10-15mm, coated with lubricating grease and dust from fat, prevent oil diffusion caused by oily mist.
