Ezweni eliguquguqukayo lemishini yezimboni, ubuqotho bemishini ejikelezayo bubaluleke kakhulu. Izivalo zemishini ze-single cartridge ziye zavela njengengxenye ebalulekile kulo mkhakha, eziklanywe ngobuhlakani ukunciphisa ukuvuza nokugcina ukusebenza kahle kwamaphampu kanye nabaxubi. Lo mhlahlandlela ophelele udlula ezinkingeni zezivalo zemishini ze-single cartridge, unikeza ukuqonda ngokwakhiwa kwazo, ukusebenza kwazo, kanye nezinzuzo eziletha ezinhlobonhlobo zezicelo zezimboni.
Kuyini i-SingleIsivalo Semishini Yekhatriji?
I-single cartridge mechanical seal iyithuluzi elenziwe ngobunjiniyela elisetshenziselwa ukuvimbela ukuvuza koketshezi emishinini ejikelezayo efana namaphampu, abaxubi, kanye neminye imishini ekhethekile. Iqukethe izingxenye eziningi ezifaka phakathi ingxenye engashintshi enamathele esitsheni semishini noma ipuleti le-gland, kanye nengxenye ejikelezayo enamathiselwe ku-shaft. Lezi zingxenye ezimbili zihlangana nobuso obufakwe ngomshini obushelelana, okudala uphawu olugcina umehluko wokucindezela, oluvimbela ukungcola, futhi olunciphisa ukulahleka koketshezi.
Igama elithi 'ikhatriji' libhekisela esimweni esihlanganisiwe salolu hlobo lwesivalo. Zonke izingxenye ezidingekayo—ubuso besivaloama-s, ama-elastomer, iziphethu, isivikelo somgodi—kufakwe kuyunithi eyodwa engafakwa ngaphandle kokudiliza umshini noma ukubhekana nezilungiselelo zokuvala eziyinkimbinkimbi. Lo mklamo wenza kube lula izinqubo zokufaka, uqondanisa izingxenye ezibalulekile ngokunembile, futhi unciphisa amaphutha okufaka angaba khona.
Ngokungafani nezivalo zezingxenye ezakhelwe phezu kwephampu ngesikhathi sokufakwa, izivalo zemishini ze-single cartridge ziyalinganiswa njengengxenye yomklamo wazo ukuze zivumelane nokucindezela okuphezulu futhi zivikele ekuphazamisekeni kobuso. Ukucushwa okuzimele akugcini nje ngokusindisa isikhathi sokulungisa kodwa futhi kuqinisekisa ukusebenza okuthembekile ngenxa yamapharamitha ahambisanayo asethwe efektri angase ahluke uma ehlanganiswe ngendlela engafanele endaweni.
Incazelo Yesici
Izivalo ezihlanganiswe kusengaphambili zilungele ukufakwa ngaphandle kokudinga ukulungiswa okuyinkimbinkimbi ngesikhathi sokuhlanganiswa.
Umklamo Olinganiselayo Wenzelwe ukusingatha izindawo ezicindezelekile kakhulu ngenkathi kugcinwa ubuqotho besakhiwo.
Izingxenye Ezihlanganisiwe Izinto eziningi zokuvala zihlanganiswe zaba iyunithi eyodwa okulula ukuyiphatha.
Ukufakwa Okulula Kunciphisa isidingo samakhono noma amathuluzi akhethekile ngesikhathi sokusetha.
Ukuthembeka Okuthuthukisiwe Imininingwane esethwe efektri iqinisekisa ukuhambisana nokunemba ekusebenzeni kahle kokuvala.
Ukuvuza Okuncishisiwe Nokungcola Kunikeza ukulawula okuqinile phezu koketshezi lwenqubo ngaleyo ndlela kugcina ukuhlanzeka nokusebenza kahle kohlelo.
Isebenza Kanjani I-Single Cartridge Mechanical Seal?
I-single cartridge mechanical seal isebenza njengedivayisi yokuvimbela ukuvuza koketshezi oluvela epompo noma komunye umshini, lapho ishafti ejikelezayo idlula khona endlini engashintshi noma ngezikhathi ezithile, lapho ishafti ijikeleza khona ishafti.
Ukuze kufezwe lokhu kugcinwa koketshezi, uphawu luqukethe izindawo ezimbili eziyinhloko eziyisicaba: olulodwa olumile nolunye olujikelezayo. Lezi zici ezimbili zenziwe ngomshini oqondile ukuze zibe ziyisicaba futhi zibanjwe ndawonye yi-spring tension, i-hydraulics, kanye nengcindezi yoketshezi oluvalwayo. Lokhu kuxhumana kudala ifilimu encane yokugcoba, ehlinzekwa ngokuyinhloko yi-process fluid uqobo, enciphisa ukuguguleka kobuso bokuvala.
Ubuso obujikelezayo bunamathele emshafini futhi buhamba nawo kuyilapho ubuso obungashukumi buyingxenye yenhlangano yesivalo ehlala ingashukumi ngaphakathi kwendlu. Ukuthembeka nokuphila isikhathi eside kwalezi zivalo kuncike kakhulu ekugcineni ukuhlanzeka kwazo; noma yikuphi ukungcola phakathi kwazo kungaholela ekugugeni noma ekwehlulekeni kusenesikhathi.
Izingxenye ezizungezile zisekela umsebenzi kanye nesakhiwo: i-elastomer bellows noma i-O-ring isetshenziselwa ukunikeza ukuvalwa kwesibili okuzungeze umgodi futhi ikhokhele noma yikuphi ukungahambisani kahle noma ukunyakaza, kuyilapho isethi yezipilingi (i-spring eyodwa noma umklamo wezipilingi eziningi) iqinisekisa ukuthi kugcinwa ingcindezi eyanele kuzo zombili izinhlangothi zesipilingi ngisho noma kukhona ukuguquguquka kwezimo zokusebenza.
Ukuze kusizwe ekupholiseni nasekususeni udoti, ezinye izivalo zemishini ze-single cartridge zihlanganisa amapulani okufaka amapayipi avumela ukujikeleza koketshezi kwangaphandle. Ngokuvamile ziza nezindlala ezihlonyiswe ngokuxhumeka kokukhipha uketshezi, ukucima nge-cooling noma i-heating medium, noma ukunikeza amakhono okubona ukuvuza.
Umsebenzi Wengxenye
Ubuso obujikelezayo Bunamathela emgodleni; Kwakha indawo yokuvala eyinhloko
Ubuso obungaguquki buhlala bunganyakazi; Buhambisana nobuso obujikelezayo
I-Elastomer Bellows/O-ring Ihlinzeka ngokuvalwa kwesibili; Ikhokhela ukungalungi kahle
Iziphethu Zisebenzisa ingcindezi edingekayo ekuvaleni ubuso
Amasu Okufaka Amapayipi (Ongakukhetha) Kwenza kube lula ukupholisa/ukuhlanza; Kuthuthukisa ukuzinza kokusebenza
Izinto Okufanele Uzicabangele Lapho Ukhetha I-Cartridge Mechanical Seal Eyodwa
Uma ukhetha uphawu olulodwa lwe-cartridge mechanical lwezicelo zezimboni, ukuqonda izici ezibalulekile ezilawula ukusebenza nokuthembeka kubaluleke kakhulu. Inqubo yokukhetha kufanele icabangele izimo ezithile zokusebenza kanye nezidingo zesicelo. Izinto ezibalulekile okufanele uzicabangele zifaka:
Izici Zoketshezi: Ulwazi lwezakhiwo zoketshezi, njengokuhambisana kwamakhemikhali, uhlobo lokuhuzuka, kanye nokuthambekela, lungathonya kakhulu ukukhethwa kwezinto zesivalo ukuqinisekisa ukuhambisana nokuphila isikhathi eside.
Ububanzi Bokucindezela Nezinga Lokushisa: Izivalo kumele zikwazi ukumelana nobubanzi obuphelele bokucindezela kanye namazinga okushisa ezizohlangana nawo lapho zisebenza ngaphandle kokwehluleka noma ukwehla.
Usayizi we-Shaft kanye nesivinini: Ukulinganisa okunembile kosayizi we-shaft kanye nesivinini sokusebenza kusiza ekukhetheni uphawu olufanele olungaphatha amandla e-kinetic akhiqizwa ngesikhathi sokusebenza.
Izinto Zokuvala: Izinto ezisetshenziselwa ukuvala ubuso kanye nezingxenye zesibili (njenge-O-rings), kumele zifanele izimo zesevisi ukuvimbela ukuguguleka noma ukwehluleka kusenesikhathi.
Imithetho Yezemvelo: Ukuthobela imithetho yezemvelo yendawo, yesizwe, noma yemboni ethile mayelana nokukhishwa kwegesi kumele kucatshangelwe ukuze kugwenywe izinhlawulo noma ukuvalwa.
Ukulula Kokufaka: I-cartridge eyodwa yokuvala kufanele ivumele ukufakwa okulula ngaphandle kokudinga ukuguqulwa okukhulu kwemishini noma amathuluzi akhethekile.
Izidingo Zokuthembeka: Ukunquma isikhathi esimaphakathi phakathi kokwehluleka (i-MTBF) ngokusekelwe kudatha yomlando kungakuqondisa ezimvilophini ezaziwa ngokuqina kwazo ngaphansi kwezimo zokusebenza ezifanayo.
Ukusebenza kahle kwezindleko: Hlola hhayi nje izindleko zokuqala kodwa nezindleko zomjikelezo wokuphila ezihlanganisa izindleko zokulungisa, isikhathi esingaba khona sokungasebenzi, kanye nemvamisa yokushintsha.
Ekuphetheni
Ekuphetheni, izivalo ze-single cartridge mechanical zinikeza inhlanganisela ekhangayo yokuthembeka, ukusebenza kahle, kanye nokulula kokufakwa okungazuzisa kakhulu izinhlelo zokusebenza eziningi zezimboni. Ngokuhlinzeka ngobuqotho bokusebenza obuthuthukisiwe kanye nokunciphisa izidingo zokulungisa, lezi zixazululo zokuvala ziwutshalomali ekude nasekusebenzeni kwemishini yakho. Kodwa-ke, ukukhetha iyunithi yesivalo efanele izidingo zakho ezithile kubalulekile ekuqinisekiseni ukusebenza kahle.
Sikumema ukuthi ujule kakhulu ezweni lama-single cartridge mechanical seals bese uthola ukuthi ubuchwepheshe bethu bungahambisana kanjani nezidingo zakho zokusebenza. Ithimba lethu elizinikele lizibophezele ekuhlinzekeni ukwesekwa okuphezulu kanye nezixazululo ezenzelwe wena ezibhekana nezinselelo zakho ezihlukile. Vakashela iwebhusayithi yethu ukuze uthole umbono oningiliziwe ngemikhiqizo yethu ebanzi noma uxhumane nathi ngqo. Abameleli bethu abanolwazi bakulungele ukukusiza ekuboneni nasekusebenziseni ikhambi eliphelele lokuvala ukuze kuthuthukiswe ukusebenza nokuthembeka kwemishini yakho.
