Metering Pumps: incazelo kanye nokubuyekeza

Uzotshala ukuphathwa izici uketshezi yesimanje inqubo amaphampu enikeziwe in izindlela manual kanye othomathikhi. Kuye ngetidzingo tekusebenta kungadinga Ukucabangela nemingcele ahlukahlukene. Ngokwesibonelo, umsebenzisi angakwazi ulungise ivolumu ukunikezela umsebenzi umfutho. Ngesikhathi esifanayo, kunezinhlobo ezithile imishini lenzelwa ezithile inkonzo abezindaba iphuzu. Lezi zihlanganisa metering amaphampu esetshenziswa izimboni ukudla, eyenza imithi namakhemikhali.

Izici kwe-futha metering

Isikali amayunithi uvumele volumetric osenyameni ukudonsa uketshezi, ukumiswa kanye emulsions. Nokho, iningi amaphampu enjalo angalondoloza abezindaba hlangothi futhi nolaka. Ngenxa yalesi sizathu, ukusetshenziswa kwazo kuvamile umkhakha zamakhemikhali. Kuye izici ezisetshenziselwa ukugeleza tube, uzimisele futhi imishini ethize injongo. Umehluko omkhulu kusuka amayunithi bendabuko yasekhaya wukuthi amaphampu nokushintsha kokudla nokufakwa akuvumela ukulungisa ingcindezi ezingeni ophumayo iphuzu ukungena nelondekile. I ngokuphelele itheku ingcindezi Inkomba ephakeme kunaleyo ngentukuthelo ayegcwele ketshezi akhishwa. Phakathi eyisisekelo izici lobuchwepheshe kanye namasistimu okusebenza imishini yikhono ngokuphawulekayo ukusebenza kwabezindaba ethize viscosity kinematic futhi ububanzi we amapayipi ndima.

Peristaltic nokushintsha kokudla nokufakwa amaphampu

Lolu hlobo nokushintsha kokudla nokufakwa futha yakhelwe ukusebenza nge uketshezi futhi izinto pasty. Umgomo we operation isekelwe isenzo mechanical esiteshini ukusebenza, okuyinto evame emelelwa tube okuqinile kodwa nokunwebeka. Okungukuthi, phakathi ukusebenza ku hose ingcindezi mechanical is wayenethonya imvelo, kanjalo Uyamkhipha u- uketshezi yokuxhuma. Ngo kweqa kanye obungazungeza ezinamasondo asetshenziswa njengoba Activator zemvelo. Ngu ukwakhiwa, metering amaphampu zaloluhlobo zinzima idivayisi ehlanganisa ipayipi nezimo futhi hose ne iqoqo ezinamasondo. Futhi ingxenye ingqalasizinda ihlinzeka ithrekhi lapho tube selibekiwe umugqa. Yilapho futhi kuba nomphumela ngokomzimba.

amayunithi ulwelwesi

Lokhu futha volumetric lapho isici yokusebenza uthatha umsebenzi design fixed ipuleti nezimo emaphethelweni. Ngokwezinga elithile, yena uba piston. Ulwelwesi flexes ngesikhatsi kokuhlinzwa, okuholela uketshezi ukufuduka. Kulokhu, umphumela amandla unganikezwa ngezindlela ezahlukene. Ngokwesibonelo, lo mkhuba usebenzisa ngemoto mechanical, amadivayisi wokubacindezela futhi womoya, okuyinto plate zikhubazekile ngokushintsha ingcindezi ekamelweni ukusebenza. Ngenxa ukungabikho gearboxes kanye izinjini, amaphampu nokushintsha kokudla nokufakwa zibhekwa ephephile kakhulu futhi enokwethenjelwa. Lokhu kubalulekile ikakhulukazi nokugcinwa yiluphi uketshezi oluvutha kalula, njengoba umsebenzi iyunithi ayinakho preconditions kumiswa Sparks.

plunger onobuhle

Kuyinto uhlobo piston wokubacindezela ezisebenza ngesisekelo ukunyakaza reciprocating. Valve ukusatshalaliswa kohlelo ayivumeli ukusetshenziswa amayunithi esinjalo isinyathelo reverse, okuyinto eveza umahluko phakathi kwabo kwamanye amadivayisi okukhulu kakhulu. Le nhlangano yenkolo yokulwela reverse of the piston kuya ipayipi okuholela circuit umphini evimbela ukuvuza medium esiteshini. Ngesikhathi esifanayo, valve osenyameni ohlangothini ivuleka, zokuphuma uketshezi ngokusebenzisa isikhala eyamukelayo. Ngo kokuhlinzwa, futha plunger metering inikeza Isivinini engalingani uketshezi, okuholela icala zako ezisemqoka. Offset umphumela ngakanye ngezindlela ezihlukahlukene, kuhlanganise ngokusebenzisa ukwethulwa ukwakha ezakhi eziningana piston.

imishini kophawu

Uma, ngenxa constructional ukubulawa Amayunithi ababulawa ngokuhambisana nezidingo ethile Isici sefomu, ngokuya okuqukethwe tekusebentisa izindlela zokulawula abakhiqizi ukuthuthukisa amazinga ajwayelekile. Ngakho, i-ND nokushintsha kokudla nokufakwa futha ihlinzeka manual transmission uketshezi isiqondiso kusukela iyunithi isicimile. Uma uhlelo evumela ukuzilawula ngokuzenzekelayo futhi akude, imishini inikezwa isiqu NDE.

Futhi, abakhiqizi ukhombise Inkomba nokushintsha kokudla nokufakwa, okuyinto ngokwesilinganiso 1-2.5. Kukhona amacebo lapho le nkomba aluboniswa. Ngokuvamile, imodeli ne Inkomba kokuqala abe Ukushisa jacket, futhi izinga eliphakeme sokuphuzisa ukunemba ephawula khona kule ngesakhiwo usinika ketshezi wokuwasha noma esangweni. Lokhu kuhlukaniswa kusebenza futhi zonke izinhlobo amayunithi. Ngokwesibonelo, plunger nokushintsha kokudla nokufakwa futha kungase kudingeke LP Inkomba kanye ngokunemba kuqala, futhi eyesibili.

Izibuyekezo abakhiqizi

Sokuphuzisa amamodeli we uzotshala imikhaya imishini hlala niche ahlukene esenziwa isicelo sabo ethize. Leli akulona ingxenye ekhaya, ngakho lokubolekwa okwandile bona lezo abakhiqizi akudingeki. Ukuthuthukiswa kulesi siqondiso yizinkampani ezinkulu ezikhethekile, kuhlanganise Etatron futhi Grundfos. Ububanzi ukuguqulwa lokuqala udumo yomenzi iwine eOne Eyisisekelo. Le yunithi ulwelwesi, lapho abasebenzisi wazi khona bokusungula ngamabomu nge high-ukucacisa uhlelo lokulawula amandla isiqondiso. Ayikho ngaphansi ngokwanele owethulwe kanye nokushintsha kokudla nokufakwa iphampa Grundfos, futhi abameleli ethile yochungechunge diaphragm DME. Abanikazi imishini enjalo ukugcizelela ukuthembeka, ukusebenza kahle ibhola valve uhlobo, kanye electronic iyunithi umsebenzi ikuvumela ukulungisa ukunemba nokushintsha kokudla nokufakwa.

isiphetho

Ingxenye imishini metering futha akunakubangelwa embonini, ngoba zinsizakuphila ngokwethukela iyasetshenziswa amabhizinisi, izinhlangano inkonzo, nokunye. D. Lokhu kuchaza izidingo ukusebenza high izingxenye zesakhiwo. Zisuke zezokuvikela nokuzinza - lawa izimfanelo eziyinhloko edingekayo zanamuhla nokushintsha kokudla nokufakwa izinhlelo. Pumps yalolu hlobo lomsebenzi e imodi kakhulu ukusebenza, ngakho abakhiqizi bafuna ukwandisa imithombo yendalo timphawu. Phakathi kwezici negative ukuhlukanisa bafake ajwayelekile izingxenye mechanical hhayi kuphela. Ngokwesibonelo, amayunithi ulwelwesi kuncane noma akukho nhlobo izingxenye ukuzihlikihla. Kodwa ukugeleza izingxenye nabo abezindaba nolaka, kumele avikelwe ekuhlaselweni zamakhemikhali.
