Kev daws teeb meem ntawm Kev Tsis Txaus Siab hauv Coarse Focusing Assembly of Microscopes
Lub ntsiab ua txhaum ntawm cov ntxhib tsom xam mechanism yog tsis siv neeg slipping thiab inconsistent nruj thaum nqa. Tsis siv neeg swb yog hais txog qhov tshwm sim uas lub raj, caj npab lossis theem maj mam nqis los ntawm nws tus kheej qhov hnyav yam tsis muaj kev hloov kho thaum nws nyob ntawm qhov chaw ruaj khov. Nws tshwm sim thaum lub gravitational quab yuam ntawm lub raj, caj npab los yog theem siab tshaj qhov kev sib txhuam zoo li qub. Txoj kev daws teeb meem yog txhawm rau ua kom muaj kev sib txhuam zoo li qub kom nws tshaj qhov hnyav ntawm lub raj lossis caj npab.
Rau qhov ntxhib focusing mechanism ntawm inclined-tube thiab feem ntau binocular microscopes, yog hais tias lub caj npab nqes down, tuav lub anti-slip log nyob rau hauv lub ntxhib focusing handwheels nrog ob txhais tes, thiab nruj nreem clockwise kom tsis txhob ntog. Yog tias txoj kev no ua tsis tiav, lub tshuab tsom iav yuav tsum tau kho los ntawm tus kws tshaj lij.
Tsis siv neeg plam ntawm lub raj feem ntau ua rau kev nkag siab yuam kev tias cov iav thiab khib meshing yog xoob dhau. Qee tus neeg ua haujlwm yog li ntxiv shims hauv qab khib. Txawm hais tias slipping tej zaum yuav tsum tau nres ib ntus, qhov no tso cov iav thiab khib nyob rau hauv ib qho txawv meshing mob. Kev txav mus tas li yuav deform ob qho tib si. Yog hais tias lub shim yog unevenly muab tso rau, lub khib yuav deform ntau heev, uas ua rau tsis sib xws meshing: nruj nyob rau hauv ib co seem thiab xoob nyob rau hauv lwm tus neeg. Li no txoj kev no tsis pom zoo.
Tsis tas li ntawd, yog hais tias lub coarse tsom mechanism tsis muaj kev saib xyuas rau lub sij hawm ntev thiab cov roj lubricating dries, lub lifting lag luam yuav hnov nkig, thiab kev sib txhuam suab nrov ntawm qhov chaw yuav hnov. Nyob rau hauv cov ntaub ntawv no, lub mechanical sib dhos yuav disassembled, ntxuav, greased thiab reassembled.
