Taw qhia: Ncuav qab zib tso kua mis yog ib qho tseem ceeb precision Cheebtsam hauv cov khoom lag luam naj hoom, uas txiav txim siab ncaj qha rau cov khoom lag luam, txee lub neej thiab hom duab.
Ib
Lub ntsiab lus ntawm ib qho naj npawb tshuaj tsw qab
Ib qho tshuaj tsw qab twj yog lub precision kho tshuab ua kua hluav taws xob ua rau cov khoom siv hluav taws xob uas tsim los rau cov ntsiab lus muaj zog, feem ntau 70%-ethanol), muaj dej siab. Nws yog feem ntau yog mounted ntawm lub caj dab ntawm ib tus naj hoom lub raj mis, thiab los ntawm nias hauv piston, nws rub ib qho nyiaj ntawm cov tshuaj tsw qab tawm ntawm lub raj mis thiab nruab nrab nws mus rau hauv cov tshuaj tsuag zoo.
Nws cov txiaj ntsig tseem ceeb yog: kev kho cov koob tshuaj zoo, ua kom pom zoo los tiv thaiv evapation thiab to muaj qhov zoo tshaj plaws ntawm kev xav, thiab zoo nkauj zoo nkauj.

Cov Qauv Ua Haujlwm Ntawm Cov Ncuav Qab Zib Twj
1. Sab nraud / cov neeg siv khoom sib xyaw tiv thaiv:
Thawb lub taub hau / nozzle: feem ntau uas tus neeg siv presses, feem ntau nrog ib qho ating nozzle (nrog lub zog me me uas hla) hauv lub pos huab. Cov khoom siv feem ntau cov yas (ABS, pom, thiab lwm yam) plated, thiab lwm yam), thiab lwm yam kev kho kom zoo nkauj.
Cover zoo nkauj: them rau sab nraud lub cev tso kua mis, nws ua lub luag haujlwm tiv thaiv thiab zoo nkauj, thiab yog ib qho tseem ceeb ntawm kev tsim qauv.
2. Cov tub ntxhais ua haujlwm / ua haujlwm ntawm lub twj tso kua mis lub cev:
Twj Chamber / tog raj kheej: Tseem ua haujlwm chamber nrog sab hauv precision precision. Cov khoom siv yuav tsum tau tiv taus cov tshuaj (piv txwv li PP, PT, PCTG, iav). Sab hauv phab ntsa ua tiav yog heev.
Piston: Reciprocating txav sab hauv lub twj tso kua mis kom tsim kev nqus thiab siab. Feem ntau yog ua los ntawm cov roj hmab-resistant roj hmab (piv txwv li EPDM, FKM fluoroelaster) lossis tshwj xeeb haum rau sab hauv phab ntsa ntawm lub twj tso ua ke los sau lub foob.
Piston Qws / Qia: txuas lub taub hau xovxwm rau lub piston thiab transmits lub zog nias. Lub qauv tsim sab hauv feem ntau muaj cov kua channel thiab valve qauv. Cov ntaub ntawv feem ntau yog pom lossis stainless hlau.
Caij nplooj ntoos hlav: muab lub resilience ntawm lub taub hau xovxwm thiab pab rov ua lub piston. Cov khoom siv yuav tsum muaj cov xeb zoo-tiv taus (feem ntau 302/304 stainless hlau), thiab nws cov elasticity ncaj qha cuam tshuam rau qhov kev xav ntawm cov xovxwm thiab rov qab ceev.
Pob Valve / Kos Valve:
Inlet pob valve: Nyob rau hauv qab ntawm lub raj xuas nrig ntawm lub cev, nws tsuas tso cai rau cov kua twj tso kua mis los ntawm lub raj mis thiab tiv thaiv backflow. Feem ntau yog iav hlaws (inert) lossis cov kuab tshuaj-resistant yas hlaws (piv txwv li ua haujlwm nrog lub rooj valve.
Qhov hluav taws xob pob valve / Sealing Bead: (muaj nyob rau qee qhov kev tsim qauv) nyob rau hauv lub piston lossis tsis tau nias, tiv thaiv cua los ntawm kev nkag mus thiab naj hoom los ntawm evaporating. Qhib thaum nias kom tso cai ua kua kom dim.
Lub rooj zaum: haum rau hauv lub pob valve thiab cov ntawv tuav nto. Cov khoom yuav tsum yog corrosion resistant thiab me ntsis nyuaj (piv txwv li pom).
Kev xuas tes ua: tso rau hauv qab ntawm lub raj mis los qhia cov kua rau hauv cov twj tso kua mis. Cov ntaub ntawv feem ntau yog PP lossis PE, qhov ntev yuav tsum tsim nyog rau hom raj mis, thiab hauv qab yog feem ntau txiav rau hauv ib qho bevelled nto lossis nrog ib tug neych los pab txhawb lub nqus ntawm cov kua.
3. Txhim Kho thiab Ntim Ntim:
Gasket / Foob: nyob nruab nrab ntawm lub twj tso kua mis thiab lub raj mis lub qhov ncauj, nws ua kom pom tseeb tias lub raj mis tau ntim los tiv thaiv kom tsis txhob muaj kev xau thiab tsis kam. Cov ntaub ntawv feem ntau epdm lossis FKM fluoroelomer, uas yuav tsum tau muaj kev tiv thaiv zoo thiab kev tawm tsam me me.
Xauv Cap / kho nplhaib: feem ntau ua los ntawm txhuas los yog yas, lub cev tso kom ruaj rau lub raj mis los ntawm kev siv tshuab txhais tau tias (kev ntaus nrig) thiab kev ntaus nrig) thiab kev sib tsoo gasket yog compressed.

Cov ntsiab lus txheej txheem ntawm cov dej tso dej
1. Cov khoom sib xyaw:
Txhua qhov chaw nyob hauv kev sib cuag nrog naj hoom (pitting, phatons, muaj peev xwm yuav muaj cov dej es ua kom muaj kev sib tw, cov pa roj av, melting, tawg, nag lossis daus.
2. Sealing Performance:
Cov lus ceeb toom zoo li qub: lub raj mis sab saum toj gasket yuav tsum zoo foob lub raj mis lauj kaub.
Dynamic sealing: Lub foob ntawm lub piston thiab phab ntsa sab hauv cov twj tso kua mis yog qhov tseem ceeb thiab yuav tsum raug tswj kom tsis txhob muaj dej cawv thiab poob ntawm aroma.
VALVE SEALING: Cov Inlet thiab Outlet Li (Yog muaj) yuav tsum kaw ntom ntom thaum tsis yog nyob rau hauv kev ua haujlwm los tiv thaiv cua ingress thiab kua dej evaporation. Kev kho tshuaj fluoride feem ntau yog siv los txhim kho cov kev sib khi saum npoo hauv inertness thiab cov nyhuv seading.
3. Atomisation kev ua tau zoo:
Lub nozzle aperture, thiab kua siab ua ke, kev sib xyaw ua ke, thiab cov qauv atomisation (piv txwv li cov kiv cua, lub khob hliav tshuaj. Nws yog ib qho tsim nyog los ua kom tiav cov nyhuv ntawm "raws li lub teeb ua pos huab" uas cov neeg siv khoom xav tau.
4Cov. Kev ntsuas ntsuas qhov tseeb thiab sib txawv:
The amount of fluid dispensed per press (typically 0.05ml - 0.2ml) must be precise and consistent, with little batch-to-batch variation.
5. Siab Xav:
Lub caij nplooj ntoos hlav yuam thiab kev sib txhuam yuav tsum tau sib npaug los muab kev du, dag zog, nrawm nrawm dua thiab "hwm" hwm kev. Mob stroke thiab kev ua yeeb yam yog cov yuam sij yog qhov tseem ceeb.
6. Volortility / Rulcarance Tuav:
Qhov no yog qhov tseem ceeb ntawm dab tsi paub qhov txawv naj hoom los ntawm cov twj ua ke zoo tib yam. Cov tshuaj oxidation thiab evaporation ntawm cov tshuaj tsw qab yog rawm cov khoom siv (tshwj xeeb yog cov viton), qee zaum kev siv cov roj ntsha ua kom huv si lossis siv lub tshuab nqus tsev tshwj xeeb ua rau huab cua txo qis.
7. Sib txuam thiab hloov tau:
Qhov loj ntawm cov twj tso kua mis (tshwj xeeb cov xov loj ntawm lub raj mis lub kaus mom) thiab qhov ntev ntawm kev xuas nrig ua kom haum rau lub raj mis. Cov zis ntawm lub twj tso kua mis yuav tsum raug yoog raws li lub viscosity thiab nto nro ntawm tus naj hoom.
8. Physico-tshuaj lom neeg ruaj khov:
Tom qab lub sij hawm ntev, cov seem tsis yog deformed, tsis yog kev laus, lub caij nplooj ntoo tsis swb, thiab kua tsis paug.
Plaub
Qhov tseem ceeb rau kev yuav khoom naj hoom
1. Txhais tau tias yuav tsum muaj:
Txheeb xyuas cov khoom nqus dej (piv txwv li, cov qauv tshuaj tsuag, cov khoom siv hluav taws xob, kev ua kom zoo nkauj (lub raj mis qhib loj, thiab lub hom phiaj.
2 . Tus neeg xa khoom yuav tsum tau txais kev tsim nyog:
Kev paub tshaj lij: Puas yog tsom rau lossis muaj kev nplua nuj hauv kev tsim cov khoom siab siab kawg-kawg naj hoom twj?
Cov cuab yeej siv technability: yog cov khoom siv R & D, pwm kev tsim kho, kev tsim khoom siv, tshwj xeeb yog cov khoom siv omisation) ua tiav?
Cov Txheej Txheem Zoo: Puas yog ntawv pov thawj los ntawm ISO 9001, ISO 22716 (GMP rau cov tshuaj pleev ib ce)?
Ua raws cai: Ua cov ntaub ntawv ua raws cov cai uas muaj feem xyuam (piv txog kev txiav txim siab, ROHS, FDA raug qhov yuav tsum tau ua)? Yog cov ntawv teev cov ntaub ntawv kev nyab xeeb cov ntaub ntawv nyab xeeb thiab tshaj tawm ntawm kev ua raws li?
Muaj peev xwm ntau lawm thiab muab cov saw hlau ruaj khov: Koj tuaj yeem lees txais cov khoom ruaj khov thiab xa khoom?
3. Cov qauv ntsuas:
Kev kuaj nruj:
Kev ntsuas kev sib xyaw: Sau lub twj tso kua mis nrog cov tshuaj tsw qab tiag tiag thiab ua kom nrawm dua (}}
Sealing kuaj: Qhov hnyav poob txoj kev (hnyav poob ntawm lub fwj ntim puv sim (simulating cua thauj qis dua), inverted xau dej, thiab lwm yam.
Kev ntsuam xyuas ua haujlwm: tshuaj tsuag cov ntim raug thiab ntsuas xwm yeem sib xws, nias qhov kev tshuaj xyuas, thim kev ntsuas nrawm (txawm tias nws tuaj yeem rov qab rov nqus cov kua).
Kev Ntsuas Lub Cev: Kev Siv Caij Nplooj Hlav, Qhov Ntsuas Qhov Tseeb ntawm Cheebtsam, Kev Kuaj Xyuas Kom Zoo Nkauj (Burrs, Plating / Txheej Zoo).
4. Cov khoom xa khoom siv thiab kev sib txuas lus:
Paub meej tias lawv lub tswv yim kev ua haujlwm, teeb meem daws teeb meem, muaj peev xwm txhim kho kev cai, kev txiav txim yam tsawg kawg nkaus muaj nuj nqis, thiab lub sijhawm ua.
5Cov. Cov nqi thiab cov ntsiab lus lag luam:
Sib piv cov nqi thaum lub rooj sib tham zoo thiab ua haujlwm kom ua haujlwm. Xav txog tag nrho cov nqi ntawm cov tswv cuab (suav nrog tus nqi ntawm cov kev pheej hmoo muaj txiaj ntsig zoo).
