Ua ntej mus kawm chemistry, nws raug nquahu kom koj paub koj tus kheej nrog cov lus nug txog dab tsi lub tripod yog dab tsi thiab nws yog dab tsi. Ib tug tuav yog siv los txhawb cov hwj, cov cuab yeej thiab lwm yam khoom siv. Cov khoom siv rau nws yog xaiv los ntawm cov hlau hnyav kom lub khib tsis poob tom qab kho lub nkoj nrog cov kua rau nws.
sawv daws yog dab tsi?
Thaum xav txog dab tsi lub tripod yog, lub hom phiaj tseem ceeb ntawm kev siv nws yog tuav cov khoom statically thiab ruaj ntseg. Scope ntawm lub khib yog dav. Ntxiv nrog rau chav kuaj, nws tuaj yeem siv rau kev tsim khoom.
Lub ntsiab lus ntawm lub koob yees duab tau pom nws txoj hauv kev rau kev tsim duab. Lub koob yees duab lossis lub taub hau ib leeg yog siv los tso lub lens lossis flash rau ntawm nws. Muaj cov qauv nrog ob peb lub mounts, qee zaum tshwj xeeb. Ua tsaug rau cov cuab yeej no, daim duab tau txais los ntawm lub kaum ntse ntse thiab tsis muaj qhov muag plooj.
Hauv chemistry thiab tshuaj, lub tripod pab dai lub khob kom sov. Feem ntau, cov raj kuaj tau muab tso rau hauv cov clamps uas tsis tuaj yeem muab tso rau ntsug. Ntau qhov kev sib txuas uas tshem tau tso cai rau koj los teeb tsa txoj haujlwm xav tau hauv qhov chaw.
Ntaus Ntaus
Cia peb txhais tias lub koob yees duab yog dab tsi:
- Ib qho khoom siv los ntawm cov cuab yeej pabcuam ntawm chav kuaj, uas ua haujlwm tuav cov nkoj thiab cov khoom siv.
- Lo lus "tripod" yog siv los hais txog kev txhawb nqa uas ib yam dab tsi kho nrog clamps lossis ties.
- Lub tripod yog tus yam ntxwv los ntawm qhov muaj cov fasteners, adjustable vertically thiab horizontally nrog clamping tabs.
- Muaj cov kab rov tav thiab ntsug. Thawj hom yog siv los tso cov raj hauv nws. Cov cuab yeej no ua rau nws yooj yim rau kev ua haujlwm nrog cov cuab yeej kuaj.
Cov kab ntsug ntsug muaj lub phaj hlau hnyav ntawm lub hauv paus, uas yog ntsia tau rau hauv cov hlau sawv ntsug. Clamps nrog paws twb txuas rau nws.
Lub cuab yeej ua los ntawm dab tsi?
Kom nkag siab tias lub koob yees duab yog dab tsi, koj yuav tsum paub koj tus kheej nrog nws cov khoom siv. Lub hauv paus feem ntau yog ua los ntawm cam khwb cia hlau. Nws yog hnyav thiab tsis cia lub khib poob. Nws qhov hnyav yog xaiv rau qhov siab tshaj plaws tau ntim nrog cov kua. Yog tias koj xaiv qhov tsis ncaj ncees lawm, koj tuaj yeem tso cov khoom thiab hlawv los ntawm cov tshuaj.
Rau cov ntim ntim ntim, cov raj ntsuas thiab lwm yam khoom siv hauv chav kuaj, kab rov tav version ntawm lub tripod nrog ob lub hauv paus, racks thiab crossover pas nrig hauv daim ntawv P tuaj yeem siv tau. ntawm cov cuab yeej xav tau txhua hnub.
Rau qhov ntim loj, ib lub lawj lossis ob lub lawj racks nrog lub hauv paus hnyav raug xaiv los txo qhov kev pheej hmoooverturning lub installation. Txhua lub hlwb muaj tus lej tshwj xeeb txhawm rau txhawm rau txhawm rau sau npe thiab zam kev tsis meej pem thaum hloov cov thawv.
khoom siv
Cov khoom siv yog cov hmoov coated nrog cov txheej txheem dej noo uas tuaj yeem tiv taus cov tshuaj tua kab mob luv luv thaum muaj xwm txheej tsis zoo. Feem ntau cov khoom siv hlau yog npog nrog yas rau saum. Qhov kev daws teeb meem no tso cai rau koj tsis txhob txhawj xeeb txog kev tau txais cov tshuaj reagents ntawm qhov chaw tripod.
Sab saum toj ntawm qhov ntsuas lub raj khib yog ua los ntawm cov yas lossis hlau nrog cov txheej silicone uas tsis ua rau cov tshuaj reagents thiab tshuaj. Nrog rau kev tsim ob-tier, hlau rods ua los ntawm stainless hlau yog siv los khov kho cov qauv.
Cov khoom raug hlau ntawm cov fasteners yog ua los ntawm cov khoom tsis muaj zog ntawm kev ua kom muaj zog, feem ntau xaiv cov tshuaj tiv thaiv corrosion.
Txhob Cia Siab
Tus nqi tseem ceeb ntawm chav kuaj tripod hauv cov txheej txheem tshuaj thiab lub cev yog kho txhua yam khoom siv kho mob. Yog li ntawd, lub hom phiaj tseem ceeb thaum xaiv cov cuab yeej tsim nyog yog kom tswj tau ntau yam hauv daim ntawv thov. Ntau tshaj 3 hom clamps feem ntau muab tso rau ntawm ib lub khib, uas hloov rau txhua qhov kev paub.
Cov khoom siv Mount tuaj yeem muaj cov khoom hauv qab no:
- Kev tswj lub rooj rau lub teeb ntsuj plig, lub hwj thiab lwm yam khoom ntawm kev paub.
- Cov tuav tuav tau txuas rau ntawm lub khib rau kev kho ntawm qhov siab.
- Cov nplhaib loj thiab me nrog cov hlua khi yog siv los ua ib qho chaw sawv ntsug rau ntau lub thawv: cov raj mis, cov raj ntsuas.
- Paws clamping lub caj pas ntawm lub tais los yog ib feem ntawm lwm yam cuab yeej.
- Retainers rau burettes.
Kev sib sau ua ke
Nyob hauv tsev kawm ntawv, hauv chav kawm chemistry, lawv pib kawm paub tias lub ntsiab lus ntawm chav kuaj tripod yog dab tsi. Txhawm rau kom nkag siab lub hom phiaj ntawm kev siv lub cuab yeej, thawj qhov yuav tsum ua yog sib sau ua ke.
Nws raug nquahu kom ua raws li qee yam ntawm kev ua:
- Lub hauv paus hnyav muab tso rau ntawm lub rooj.
- Lub rooj zaum yog ntsia hlau rau hauv, kev sib txuas yog ruaj ruaj nrog tus yuam sij.
- Ua ntej, lub tshuab tig lub rooj sib dhos yog strung ntawm lub khib.
- Qhov txuas ntxiv yog xaiv los ntawm tus kws pab kuaj mob ntawm nws tus kheej rau kev ua haujlwm tshwj xeeb.
- Thaum zawm fasteners, nws tsis pom zoo kom siv lub zog ntau dhau. Kev ntseeg siab ntawm qhov kev sib txuas ntawm qhov tshwm sim yuav tsum tau kuaj xyuas los ntawm nias ua ntej muab cov tais diav nrog cov tshuaj rau nws. Kev siv cov qauv txheej txheem rau lub hom phiaj tsis yog los ntawm cov chaw tsim khoom ua rau muaj kev pheej hmoo ntawm kev tawg ntawm lub tripod. Nws kuj tsis tsim nyog tshaj qhov tsim nyog load, lub khib yuav tsis tiv taus, thiab tag nrho cov qauv yuav poob rau ntawm nws sab.
Ua tib zoo mloog rau qhov chaw mounting ntawm lub tripod. Nws yuav tsum yog theem nrog kev hwm rau kab rov tav. Rau kev sim kuaj, nws yog txwv tsis pub muab tso rau ib qho twgkhoom nyob rau hauv thiaj li yuav dlhos tus qauv. Lub rooj sim yuav tsum muaj kev nruj zoo thiab muaj lub tiaj tiaj.
Yuav xaiv tus qauv twg?
Thaum saib cov qauv uas twb muaj lawm, txiav txim siab qhov tseem ceeb ntawm lub koob yees duab hauv chemistry. Rau ib txoj haujlwm tshwj xeeb, nws yuav tsum xaiv cov yam ntxwv tsim nyog: tus naj npawb ntawm cov fasteners, qhov siab thiab hom khib, qhov hnyav ntawm lub hauv paus, hom txheej ntawm cov khoom. Yog tias tsis muaj leej twg ua qhov kev sim ntxiv, ces qhov kev siv nyiaj ntxiv rau kev yuav khoom kim heev yuav tsis muaj nuj nqis.
Nrog me me ntawm cov kua aggressive, nws raug tso cai siv hlau tripods ua los ntawm galvanized lossis stainless hlau. Cov khoom siv polypropylene yog nyob rau hauv kev thov rau kev ua haujlwm nrog cov raj xa dej. Ob txhais ceg ntawm cov tuav tau xaiv nrog cov txheej txheem silicone kom tsis txhob ua rau lub iav nto ntawm lub khob thaum clamping.
khoom xav tau
Thaum kuaj xyuas ib lub koob yees duab, ua tib zoo saib xyuas cov yam ntxwv hauv qab no:
- Lub zog ntawm cov khib nyiab thiab kho cov khoom yuav tsum ntau dua li ob peb zaug ntawm qhov hnyav ntawm cov khoom thiab cov tais diav siv txhua hnub.
- sawv qhov siab yog xaiv me ntsis ntau dua li qhov xav tau.
- Yuav tsum tau ntim cov roj hmab los kho cov tais diav uas tsis muaj cov ntsiab lus txuas tshwj xeeb.
- Txhua lub qhov dej yuav tsum tau sau nrog cov tsiaj ntawv thiab cov lej yog tias siv lub raj khib nyiab. Tus nqi ntawm qhov kev nthuav dav no raug kuaj xyuas hauv kev xyaum, qhov no tso cai rau koj kom pom lub thawv zoo thiab tsis txhob cuam tshuam nrog lwm cov reagents.
- MuajTxhua yam ntawm cov nplhaib, ties, mounts rau ib hom kev paub.
- Resistance rau tripod kub yog muab rau hauv tus account.
- Lub hauv paus ntsiab lus ntawm kev tshem tawm thiab kev sib dhos, nrog rau kev yooj yim hauv kev khaws cov khoom tsim.
Universal rack qauv yog nyiam nyob rau hauv ib qho chaw kuaj. Hauv tsev kawm ntawv, qhov no yog qhov tseeb tshwj xeeb vim muaj cov npe loj ntawm ntau yam kev sim hauv cov lus qhia ntawm chemistry, biology, thiab physics. Thiab coob tus tub ntxhais kawm tsis pub xaiv cov qauv tripod ntawm lub zog tsis muaj zog. Kuj tseem ceeb yog qhov yooj yim ntawm kev sib dhos, tsis tas siv cov yuam sij ntxiv.
Kev Tiv Thaiv Kev Tiv Thaiv
Rau cov khoom siv kho mob kom raug, nws raug nquahu kom koj nyeem cov lus qhia txuas nrog. Tag nrho cov fastening qhov chaw ntawm cov qauv yuav unscrewed tsuas yog tom qab cov reagents tau raug tshem tawm ntawm qhov chaw ua hauj lwm. Cov kua dej ntws ntau li ntau tau. Yog kub, muab sijhawm kom txias.
Flasks raug pom zoo kom tshem tawm ntawm ob txhais ceg hauv lub xeev kaw. Nrog rau ob peb lub ntsiab lus clamping, lub tab sab saud yog thawj zaug unscrewed, tom qab ntawd cov ntim khoom ntxiv tau raug tshem tawm raws li ntu. Tsis tas yuav sim loosen cov fasteners ntawm cov clamps tam sim ntawd ntawm lub khib. Ua ntej tshaj plaws, cov ceg raug tso tawm, ncaj qha tuav caj pas ntawm lub khob nws tus kheej.
