Kodi Kupatukana kwa Centrifuge ndi chiyani? - Wopanga Centrifuge | ZONELINK

Momwe centrifuge imagwirira ntchito

Makina oyeretsera madzi ndi makina omwe amagwiritsa ntchito mphamvu ya centrifugal kulekanitsa zigawo kuchokera ku tinthu tamadzimadzi ndi tolimba kapena chisakanizo cha madzi ndi madzi. Ma centrifuge amagwiritsidwa ntchito makamaka kulekanitsa tinthu tamadzimadzi ndi madzi omwe ali mu suspension; kapena kulekanitsa madzi awiri osasakanikirana amitundu yosiyanasiyana mu emulsions (monga kulekanitsa kirimu ndi mkaka); ingagwiritsidwenso ntchito kuchotsa Madzi mu zinthu zolimba zonyowa, monga kuumitsa zovala zonyowa ndi makina ochapira; olekanitsa machubu apadera a ultra-speed amathanso kulekanitsa zosakaniza za mpweya zamitundu yosiyanasiyana; pogwiritsa ntchito mawonekedwe a kuchulukana kosiyana kapena kukula kwa tinthu tamadzimadzi tolimba mu zakumwa zomwe zili ndi liwiro losiyana la sedimentation, zina zoyeretsera madzi. Ma Centrifuge amathanso kugawa tinthu tamadzimadzi ndi kuchuluka kapena kukula kwa tinthu tamadzimadzi.

Pamene choyimitsira chokhala ndi tinthu tating'onoting'ono chimaima chilili, tinthu toyimitsidwa timamira pang'onopang'ono chifukwa cha mphamvu yokoka. Tinthu tolemera kwambiri timamira mofulumira, pomwe tinthu tomwe tili ndi mphamvu yochepa kuposa madzi timayandama mmwamba. Liwiro limene tinthu timayenda mu mphamvu yokoka limakhudzana ndi kukula, mawonekedwe, ndi kuchuluka kwa tinthuto, komanso mphamvu ya mphamvu yokoka ndi kukhuthala kwa madziwo. Tinthu tating'onoting'ono tomwe tili ndi maselo ofiira a magazi, okhala ndi mainchesi angapo, timatha kuoneka kuti takhazikika pansi pa mphamvu yokoka yachibadwa.

Kuphatikiza apo, pamene chinthucho chikhazikika mu sing'anga, chimaphatikizidwa ndi chochitika cha kufalikira. Kufalikira sikopanda malire ndipo ndi kopanda malire. Kufalikira kumagwirizana mosiyanasiyana ndi kulemera kwa chinthucho, ndipo tinthu tating'onoting'ono tikakhala tating'onoting'ono, kufalikira kumakhala koopsa kwambiri. Kutsika kwake kumakhala kofanana komanso kokhazikika, ndipo kumafunika kupatsidwa mphamvu yakunja kuti kusunthe. Kutsika kwake kumakhala kofanana ndi kulemera kwa chinthucho, tinthu tating'onoting'ono tikakhala tating'onoting'ono tikakhala tating'onoting'ono, kutsika kwake kumakhala kofulumira. Pa tinthu tating'onoting'ono tomwe tili ndi ma microns ochepa, monga ma virus kapena mapuloteni, timakhala mu colloidal kapena semi-colloidal state mu yankho, ndipo sizingatheke kuwona njira ya kusungunuka kokha ndi mphamvu yokoka. Chifukwa tinthu tating'onoting'ono tikakhala tating'ono, kusungunuka kwake kumakhala kochedwa, komanso kufalikira kwake kumakhala koopsa kwambiri. Chifukwa chake, ndikofunikira kugwiritsa ntchito centrifuge kuti mupange mphamvu yamphamvu ya centrifugal kuti mukakamize tinthuti kuti tigonjetse kufalikira ndikupanga kayendedwe ka kusungunuka.

Kutsegula centrifugation ndi kugwiritsa ntchito mphamvu yamphamvu ya centrifugal yopangidwa ndi kuzungulira kwa liwiro la centrifuge rotor kuti ifulumizitse liwiro la sedimentation la tinthu tating'onoting'ono mumadzimadzi, ndikulekanitsa zinthuzo ndi ma sedimentation coefficients osiyanasiyana ndi kuchulukana kwa buoyancy mu chitsanzocho.

Kusintha pakati pa mphamvu ya centrifugal (g) ndi liwiro lozungulira (rpm)

Fomula yosinthira pakati pa mphamvu ya centrifugal G ndi liwiro lozungulira RPM ndi iyi:

G=1.11×10^(-5)×R×(rpm)^2

Pakati pawo, G ndi mphamvu ya centrifugal, yomwe nthawi zambiri imafotokozedwa ngati multiple of g (kuthamanga kwa mphamvu yokoka).

10^(-5) ndi mphamvu yachisanu yotsutsa ya 10, sikweya ya liwiro lozungulira (rpm)^2, R ndiye radius, ndipo unit ndi masentimita.

Mwachitsanzo, ndi utali wa centrifugal wa 10 cm ndi liwiro lozungulira la 8000 RPM, mphamvu ya centrifugal ndi:

G=1.11*10(-5)*10*(8000)2=7104

Ndiko kuti, mphamvu ya centrifugal ndi 7104g.

Ndipo mphamvu ya centrifugal ikakhala 8000g, liwiro lake liyenera kukhala: 8489 ndi pafupifupi 8500rpm

Kodi mungagule bwanji?

Pali mitundu yambiri ya ma centrifuge, ndipo mtengo wake ndi wokwera mtengo. Mukamagula, muyenera kuyeza malinga ndi ntchitoyo. Nthawi zambiri zinthu zotsatirazi ziyenera kuganiziridwa:

(1) Cholinga cha centrifugation, analytical centrifugation kapena kukonzekera centrifugation;

(2) Mtundu ndi kuchuluka kwa chitsanzo, kaya ndi maselo, mavairasi, kapena mapuloteni, ndi kukula kwa chitsanzocho. Kutengera ndi zinthu izi, chisankho chogula centrifuge yowunikira kapena yokonzekera; centrifuge yothamanga pang'ono, yothamanga kwambiri, kapena yothamanga kwambiri; centrifuge yothamanga kwambiri, yokhazikika, kapena yotsika kwambiri.

(3) Kuthekera kwachuma: Pamene chitsanzocho chatsimikiziridwa, wopanga ndi mtengo wake ziyenera kuganiziridwa. Mtengo ndi magwiridwe antchito a chinthucho zimagwirizanitsidwa.

(4) Zina: monga ngati ntchito ya centrifugal ndi yosavuta, ngati kukonza kuli kosavuta, ngati kapangidwe kake ndi kakale, ngati kupezeka kwa zida zovalira kuli kosavuta, ndi zina zotero.

(5) Vuto lofanana: sizingatheke kuti centrifuge igwire ntchito mothamanga pang'ono, mothamanga kwambiri komanso mopitirira muyeso nthawi imodzi. Kawirikawiri, ma ultracentrifuge amangogwiritsidwa ntchito poyesa mphamvu kwambiri, osati poyesa mphamvu kwambiri, komanso poyesa mphamvu pang'ono, komanso ma centrifuge othamanga kwambiri sali oyenera poyesa mphamvu pang'ono. Chifukwa chake, pogula ultracentrifuge, ndikofunikira kuganizira za centrifuge yothamanga kwambiri, apo ayi ubwino wake sudzaperekedwa. Kawirikawiri, liwiro lotsika komanso liwiro lalikulu zimagwiritsidwa ntchito mobwerezabwereza, pomwe kuchuluka kwa ma ultracentrifuge ndi kochepa. Ma ultracentrifuge amagulidwa m'ma laboratories omwe nthawi zambiri amagwiritsidwa ntchito kapena kuganizira malo opezeka anthu ambiri m'madera osiyanasiyana.

Pambuyo poti chitsanzo cha centrifuge chadziwika, ndi mtundu wa rotor ya centrifugal yomwe muyenera kusankha. Chofunika kwambiri ndi mphamvu ya chitsanzo ndi momwe centrifuge imagwirira ntchito. Nthawi zambiri, pamakhala rotor imodzi yopingasa ndi rotor imodzi ya angular, kapena rotor imodzi yayikulu (yotsika liwiro) ndi rotor imodzi yaying'ono yothamanga kwambiri kuti ikwaniritse zosowa zosiyanasiyana pantchito. Ikakhala yokwanira bwino, imakhala yabwino kwambiri. Chifukwa pali mitundu yambiri ya ma rotor a centrifugal, ambiri mwa iwo ndi ofanana, ndipo ma rotor a makina othamanga kwambiri ndi okwera mtengo kwambiri. Ngati onse akugwirizana, mtengo wake ndi wokwera kangapo kuposa wa centrifuge host, ndipo sizofunikira. Chifukwa cha liwiro losiyana la rotor, mtengo wake umasiyana kwambiri. Ponena za liwiro lozungulira, sikoyenera kutsatira kwambiri momwe mungathere, koma payenera kukhala rotor yokhala ndi liwiro lozungulira kwambiri lomwe centrifuge imavomereza, apo ayi idzakhala yopanda ntchito kwa centrifuge. Mayunitsi okhala ndi ma centrifuge awiri angaganizire mitundu yowonjezera ya rotor kuti asunge ndalama.

Kuyang'anira ma centrifuge, malinga ndi kugwiritsa ntchito ma centrifuge ku China kwa zaka zambiri, mitundu yonse ya ma centrifuge iyenera kuyang'aniridwa ndikusamalidwa ndi antchito apadera. Ma centrifuge amphamvu komanso othamanga kwambiri amafunika kuyang'aniridwa ndi kusamalidwa nthawi zonse. Ogwiritsa ntchito ayenera kulemba momwe amayesera komanso momwe amasamalirira mwatsatanetsatane kuti atsimikizire kuti centrifuge ikugwiritsidwa ntchito bwino. Ma centrifuge amphamvu komanso otsika kwambiri ndi osavuta kugwiritsa ntchito, kotero mutha kuwagwiritsa ntchito nokha mutawerenga malangizo ndikuphunzira njira zogwiritsira ntchito ma centrifuge. Ma centrifuge amphamvu ali ndi kapangidwe kovuta komanso njira zovuta zogwirira ntchito. Kugwiritsa ntchito molakwika kumabweretsa ngozi. Makamaka, rotor ya centrifugal iyenera kusamalidwa mosamala ndikugwiritsidwa ntchito. Poganizira momwe amagwiritsidwira ntchito kunyumba ndi kasamalidwe ka zaka zambiri, kusunga ndi kugwiritsa ntchito chidacho ndiye chitsimikizo kuti chidacho chili bwino. Oyang'anira ndi ogwiritsa ntchito ayenera kuphunzitsidwa kuti asamangodziwa bwino momwe amagwirira ntchito, komanso kuti amvetsetse chidacho.
