Dab tsi yuav tsum tau ceev faj txog kev nyab xeeb thaum teeb tsa thiab ua haujlwm?

Thaum ua haujlwm arotary nqus evaporatorhauv chav kuaj, kev nyab xeeb yog qhov tseem ceeb. Ua ntej dhia mus rau hauv cov txheej txheem teeb tsa thiab kev ua haujlwm, nws yog ib qho tseem ceeb kom ntseeg tau tias koj muaj cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) ntawm tes. Qhov no suav nrog tsom iav kev nyab xeeb, hnab looj tes, thiab lub tsho (lab) los tiv thaiv koj tus kheej los ntawm kev phom sij. Tsis tas li ntawd, xyuas kom meej tias qhov chaw ua haujlwm tau zoo-ventilated los tiv thaiv cov vapors tsub zuj zuj.

Thaum lub sijhawm teeb tsa, ua tib zoo nyeem cov chaw tsim khoom cov lus qhia thiab paub koj tus kheej nrog cov khoom siv. Xyuas kom meej tias tag nrho cov khoom sib dhos tau ruaj ntseg, thiab xyuas ob npaug rau kev sib txuas kom tiv thaiv kom tsis txhob xau. Ua ntej yuav pib nrog ib qho kev sim, tshuaj xyuas lub cuab yeej kom pom tias muaj kev puas tsuaj lossis hnav uas tuaj yeem cuam tshuam kev nyab xeeb.

Thaum nws los txog rau kev ua haujlwm, ib txwm pib nrog kev tshuaj xyuas tag nrhorotary nqus evaporator. Tshawb xyuas lub tshuab nqus tsev twj tso kua mis rau kev ua haujlwm kom zoo thiab xyuas kom meej tias tag nrho cov li qub thiab cov tswj tau ua haujlwm zoo. Tsis txhob tso cov khoom siv tsis tu thaum nws khiav, vim qhov no tuaj yeem ua rau muaj xwm txheej lossis ua haujlwm tsis zoo.

 

Puas muaj kev pheej hmoo cuam tshuam nrog kev tuav cov kuab tshuaj hauv qhov system?

 

Kuaj cov kuab tshuaj nyob rau hauv arotary nqus evaporatorua rau muaj qee yam kev pheej hmoo uas yuav tsum tau hais kom muaj kev nyab xeeb ua haujlwm. Ib qho ntawm cov kev txhawj xeeb tseem ceeb yog qhov muaj peev xwm rau cov kuab tshuaj vapors kom sib sau thiab tsim kom muaj cua sov. Txhawm rau txo qhov kev pheej hmoo no, ib txwm siv cov evaporator rotary nyob rau hauv qhov chaw uas muaj cua zoo thiab tsis txhob tshaj cov kuab tshuaj uas tau pom zoo.

Lwm qhov kev pheej hmoo yuav xav txog yog raug rau cov tshuaj phem. Ntau cov kuab tshuaj siv hauv kev sim kuaj yuav ua rau muaj kev phom sij yog tias nqus tau los ntawm daim tawv nqaij. Txhawm rau txo qhov raug, hnav PPE tsim nyog thiab ua raws li cov txheej txheem kev nyab xeeb tsim thaum tuav thiab xa cov kuab tshuaj.

Tsis tas li ntawd, muaj kev pheej hmoo ntawm implosion yog tias lub siab nyob rau hauv lub rotary evaporator chamber ua siab dhau. Txhawm rau tiv thaiv qhov no, tsis txhob siv cov cuab yeej siv siab tshaj qhov kev txwv siab thiab ib txwm siv cov yam ntxwv kev nyab xeeb xws li lub siab nyem li qub.

Yuav ua li cas tu cov txheej txheem yuav tsum ua kom muaj kev nyab xeeb?

Txhawm rau tswj kev nyab xeeb thiab ua haujlwm ntawm arotary nqus evaporator, kev saib xyuas tsis tu ncua yog qhov tseem ceeb. Pib los ntawm kev ua niaj hnub tshuaj xyuas cov cuab yeej los txheeb xyuas cov cim qhia ntawm kev hnav lossis kev puas tsuaj. Hloov cov khoom hnav raws li xav tau thiab xyuas kom meej tias tag nrho cov ntsaws ruaj ruaj thiab kev sib txuas yog nruj kom tiv thaiv kom tsis txhob xau.

Kev huv huv kuj tseem ceeb heev rau kev ua haujlwm nyab xeeb. Tom qab txhua qhov kev siv, ua kom huv si huv lub evaporator thiab tag nrho cov iav uas cuam tshuam kom tshem tawm cov kuab tshuaj seem lossis cov khoom paug. Ua tib zoo saib xyuas thaj chaw uas cov kuab tshuaj tuaj yeem sib sau ua ke, xws li evaporating flask thiab condenser.

Ntxiv nrog rau kev tu txhua hnub, nws tseem ceeb heev uas yuav tsum ua cov haujlwm tu ncua xws li lubricating txav qhov chaw thiab ntsuas ntsuas ntsuas. Ua raws li cov chaw tsim khoom cov lus pom zoo rau kev saib xyuas ncua sij hawm thiab cov txheej txheem kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb.

Los ntawm kev ua raws li cov kev tiv thaiv kev nyab xeeb thiab kev saib xyuas cov txheej txheem no, koj tuaj yeem ua haujlwm ruaj ntseg ntawm lub tshuab nqus tsev vacuum hauv chav kuaj thiab txo qhov kev pheej hmoo ntawm kev raug mob lossis raug mob.
