Ua tiav kev daws teeb meem rau centrifuge tsis ua haujlwm

Sijhawm: 2022-01-24 Ntaus: 100

1. Qhov chaw tsis raug: centrifuge feem ntau yog muab tso rau hauv qhov chaw qhuav kom deb ntawm tshav ntuj ncaj qha. Lub peev xwm ua kom sov ntawm lub centrifuge yog qhov loj, thiab tsis muaj cov khoom siv yuav tsum tau muab tso rau ntawm lub centrifuge. Qhov kev ncua deb ntawm phab ntsa, baffle thiab lwm yam airtight thiab tsis zoo cua sov dissipation khoom yuav tsum yog tsawg kawg yog 10 cm. Nyob rau tib lub sijhawm, lub centrifuge yuav tsum muab tso rau hauv ib chav kom deb li deb tau, thiab cov organic reagents thiab inflammables yuav tsum tsis txhob muab tso rau ib puag ncig.

2. Cov kev tiv thaiv kev tiv thaiv tsis zoo tag nrho: tom qab txhua qhov kev siv, lub hau npog ntawm lub centrifuge yuav tsum tau qhib kom cov cua sov los yog dej vapor evaporate lawm. Yog tias qhov kub thiab txias centrifugation tau siv ua ntej thiab tej zaum yuav muaj dej khov, nws yuav tsum tau tos kom cov dej khov yaj thiab so nws nrog cov paj rwb qhuav hauv lub sijhawm, thiab tom qab ntawd npog nws thaum tsis muaj dej vapor pom tseeb. Yog tias lub taub hau tig ntawm lub centrifuge tuaj yeem hloov tau, txhua lub taub hau tig yuav tsum tau muab tshem tawm hauv lub sijhawm tom qab siv, ntxuav nrog cov ntaub qhwv huv thiab qhuav qhuav, thiab muab tso rau pem hauv ntej. Tsis txhob siv cov cuab yeej ntse los khawb. Aluminium rotating taub hau yuav tsum tau ntxuav tas li. Nyob rau tib lub sijhawm, lub centrifuge yuav tsum tau khaws cia thiab kho ntau zaus. Lub zog hluav taws xob yuav tsum raug txiav tawm thaum tus neeg teb xov tooj tawm mus. Thawj zaug cov neeg siv, thov sab laj cov neeg ua haujlwm uas tau siv nws ua ntej lossis xa mus rau phau ntawv. Tsis txhob siv qhov muag tsis pom kev.

3. Cov teeb meem kev ua haujlwm yuam kev: peb yuav tsum xyuam xim rau txhua yam thaum peb siv nws. Tom qab xaiv lub rotating lub taub hau thiab teeb qhov tsis, lub centrifuge yuav tsum tau soj ntsuam ib pliag. Tom qab ncav cuag qhov siab tshaj plaws ceev thiab ruaj khov, lub centrifuge tuaj yeem tawm mus. Yog tias koj hnov ​​​​lub suab txawv txav lossis hnov ​​​​tsw ib yam dab tsi thaum lub sijhawm ua haujlwm, nres tam sim ntawd, nias lub pob "stop", thiab txiav tawm lub hwj chim yog tias tsim nyog. Cov raj centrifugal yuav tsum tau muab tso rau hauv symmetrically, thiab cov raj centrifugal sib txuas yuav tsum sib npaug ntawm qhov hnyav kom deb li deb tau. Thaum lub sijhawm ua haujlwm ntawm qhov ntsuas, nws yog txwv tsis pub qhib lub centrifuge npog kiag li! Nyob rau tib lub sijhawm, nws yog qhov tsim nyog rau txhua tus neeg ua haujlwm hauv chav kuaj kom tsim tau tus cwj pwm zoo rau kev sau npe. Ua ntej, lawv tuaj yeem paub leej twg tau siv lub centrifuge ua ntej thiab qhov xwm txheej ntawm qhov ntsuas thaum nws tau siv ua ntej; thib ob, peb tuaj yeem paub cov sijhawm siv centrifuge, kom paub seb nws puas yuav tsum tau kho lossis hloov.

4. Kev sib tsoo: vim yog siv lub centrifuge ntau zaus, kev puas tsuaj thiab kev sib tsoo ntawm lub tshuab yog siab. Qhov laj thawj tseem ceeb yog kev ua haujlwm tsis raug ntawm cov neeg ua haujlwm hauv chav kuaj. Cov teeb meem tshwm sim yog: lub hau npog tsis tuaj yeem qhib tau, lub raj centrifugal tsis tuaj yeem tshem tawm, thiab lub centrifuge tsis ua haujlwm tom qab nias tus yuam sij. Cov teeb meem loj dua muaj xws li kev khoov ntawm lub rotating ncej tshwm sim los ntawm lub zog tsis sib xws, lub cev muaj zog raug hlawv tawm, thiab lub thoob kab rov tav raug muab pov tseg rau kev raug mob hnyav thiab txawm tias raug mob.

5. Qhov teeb meem tsis sib npaug: thaum siv ntau yam centrifuges, lub raj centrifugal thiab nws cov ntsiab lus yuav tsum raug sib npaug ntawm qhov sib npaug ua ntej. Qhov sib txawv ntawm qhov hnyav thaum ntsuas yuav tsum tsis pub tshaj qhov ntau tau teev tseg hauv phau ntawv qhia ntawm txhua lub centrifuge. Lub taub hau sib txawv ntawm txhua lub centrifuge muaj lawv tus kheej tso cai sib txawv. Ib tus naj npawb ntawm cov raj yuav tsum tsis txhob ntim rau hauv lub taub hau tig. Thaum lub taub hau tig tsuas yog ib nrab loaded, cov yeeb nkab yuav tsum tau muab tso rau hauv symmetrically nyob rau hauv lub rotor kom lub load yog sib npaug zos rau ib ncig ntawm lub rotor.

6. Precooling: thaum centrifuging ntawm qhov kub thiab txias ntawm chav tsev. Lub taub hau tig yuav tsum tau txias ua ntej hauv lub tub yees lossis hauv chav hloov taub hau ntawm lub centrifuge ua ntej siv.

7. Tshaj ceev: txhua lub taub hau tig muaj nws qhov siab tshaj plaws uas tso cai rau kev ceev thiab kev txwv tsis pub siv. Thaum siv lub taub hau teb, koj yuav tsum sab laj nrog phau ntawv qhia thiab tsis txhob siv nws ceev heev. Txhua qhov tig yuav tsum muaj cov ntaub ntawv siv los sau cov sijhawm siv ntau ntxiv. Yog tias qhov siab tshaj plaws ntawm kev siv lub voj voog yog dhau, qhov ceev yuav tsum raug txo raws li cov cai.

8. Yog tias tsis muaj teeb meem, xyuas seb lub band hloov lossis rheostat puas puas lossis raug txiav. Yog hais tias nws puas los yog txiav, hloov nws. Yog hais tias nws puas lawm los yog disconnected, hloov cov khoom puas thiab rewire cov hlau. Yog tias tsis muaj teeb meem, xyuas seb lub tshuab hluav taws xob sib nqus ntawm lub cev puas tawg lossis qhib (sab hauv). Yog tias nws tawg lawm, rewelding tuaj yeem ua tau Yog tias qhib Circuit Court hauv lub kauj, tsuas yog rewind lub kauj.

9. Lub cev muaj zog tsis tuaj yeem ncav cuag qhov ntsuas ceev: ua ntej kuaj cov kabmob, yog tias cov kabmob puas lawm, hloov cov kabmob. Yog tias cov kabmob tsis muaj roj lossis av ntau dhau, ntxuav cov kabmob thiab ntxiv roj. Xyuas seb qhov commutator nto yog txawv txav los yog seb cov txhuam hniav sib tw nrog lub commutator flashover nto. Yog hais tias lub commutator nto yog txawv txav, yog hais tias muaj ib tug txheej ntawm oxide, nws yuav tsum tau polished nrog zoo sandpaper Yog hais tias lub commutator tsis phim nrog txhuam, nws yuav tsum tau kho kom zoo nyob rau hauv lub xeev kev sib cuag. Yog tias tsis muaj teeb meem saum toj no, xyuas seb puas muaj luv luv Circuit Court hauv rotor coil. Yog hais tias muaj, rewind lub coil.

10. Kev vibration hnyav thiab nrov nrov: xyuas seb puas muaj teeb meem tsis txaus ntseeg. Lub txiv ntoo kho lub tshuab yog xoob. Yog tias muaj, nruj nws. Xyuas seb cov kabmob puas puas lossis khoov. Yog tias muaj, hloov cov kabmob. Lub tshuab npog yog deformed los yog nws txoj hauj lwm tsis raug. Yog tias muaj kev sib txhuam, kho nws.

11. Thaum nws txias, lub iav qis tsis tuaj yeem pib: cov roj lubricating solidifies lossis cov roj lubricating deteriorates thiab dries thiab sticks. Thaum pib, koj tuaj yeem siv koj txhais tes los pab tig rov qab los yog pib pib rov ua dua tom qab ntxuav.
