Ukwakheka nokusebenza kwezigxivizo zemishini kuyinkimbinkimbi, kuhlanganisa izingxenye ezimbalwa eziyinhloko. Zenziwe ngobuso bezimpawu, ama-elastomer, ama-seal seal, ne-hardware, ngayinye inezici nezinjongo ezihlukile.

Izingxenye eziyinhloko ze-mechanical seal zihlanganisa:

1. Ubuso Obuphendukayo (Indandatho Eyinhloko):Lena ingxenye yophawu lwemishini ezungeza ne-shaft. Ivamise ukuba nobuso obuqinile, obungagugi obenziwe ngezinto ezifana nekhabhoni, i-ceramic, noma i-tungsten carbide.
2. Ubuso Obunganyakazi (Isihlalo noma Indandatho Yesibili):Ubuso obumile buhlala buqinile futhi abuphenduki. Ngokuvamile yenziwe ngezinto ezithambile ezihambisana nobuso obuphendukayo, okudala isixhumi esibonakalayo sophawu. Izinto ezijwayelekile zifaka i-ceramic, i-silicon carbide, nama-elastomer ahlukahlukene.
3. Ama-Elastomers:Izingxenye ze-Elastomeric, njenge-O-rings nama-gaskets, zisetshenziselwa ukunikeza uphawu oluguquguqukayo noluvikelekile phakathi kwendlu emile kanye ne-shaft ejikelezayo.
4. Izinto Zokuvalwa Kwesibili:Lokhu kufaka phakathi ama-O-rings wesibili, ama-V-rings, noma ezinye izakhi zokuvala ezisiza ukuvimbela ukungcola kwangaphandle ukuthi kungangeni endaweni yokuvala.
5. Izingxenye Zensimbi:Izingxenye zensimbi ezihlukahlukene, njenge-metal casing noma i-drive band, zibamba isigxivizo esisebenza ndawonye futhi sivikeleke ezintweni zokusebenza.

Ubuso be-Mechanical seal

• Ubuso be-seal obujikelezayo: Iringi eyinhloko, noma ubuso bophawu obuzungezayo, buhamba ngokuhambisana nengxenye yomshini ojikelezayo, ngokuvamile i-shaft. Le ndandatho ivame ukwakhiwa ngezinto eziqinile, eziqinile njenge-silicon carbide noma i-tungsten carbide. Idizayini yeringi eyinhloko iqinisekisa ukuthi ingakwazi ukusekela amandla okusebenza kanye nokungqubuzana okukhiqizwa phakathi nokusebenza komshini ngaphandle kokuguqulwa noma ukuguga ngokweqile.

• Ubuso bophawu olungamile: Ngokungafani neringi yokuqala, iringi yokukhwelana ihlala imile. Idizayinelwe ukwakha ipheya evalayo eneringi yokuqala. Nakuba imile, iklanyelwe ukuthwala ukunyakaza kweringi eyinhloko kuyilapho igcina uphawu oluqinile. Indandatho yokukhwelana ivame ukwenziwa ngezinto ezifana nekhabhoni, i-ceramic, noma i-silicon carbide.

Ama-Elastomers (ama-O-rings noma ama-bellows)

Lezi zakhi, ngokuvamile ama-O-rings noma izivunguvungu, zinikeza ukunwebeka okudingekayo ukuze kugcinwe uphawu phakathi komshini wokuhlanganisa uphawu kanye nomphini womshini noma indlu. Zivumela ukungahambi kahle kweshaft nokundindizela ngaphandle kokuphazamisa ubuqotho bophawu. Ukukhethwa kwempahla ye-elastomer kuncike ezintweni ezahlukahlukene, okuhlanganisa izinga lokushisa, ingcindezi, kanye nemvelo yoketshezi oluvalwayo.

Izimpawu zesibili

Izigxivizo zesibili ziyizingxenye ezihlinzeka ngendawo yokuvala emile ngaphakathi komhlangano wokuvala uphawu. Bathuthukisa ukusebenza nokuthembeka kophawu, ikakhulukazi ezimeni eziguquguqukayo.

Izingxenyekazi zekhompuyutha

• Iziphethu: Iziphethu zinikeza umthwalo odingekayo ebusweni be-seal, ukuqinisekisa ukuthintana njalo phakathi kwabo ngisho nangaphansi kwezimo zokusebenza ezihlukene. Lokhu kuthintana njalo kuqinisekisa uphawu oluthembekile nolusebenzayo kukho konke ukusebenza komshini.

• Abagcini: Abagcini babamba izingxenye ezihlukahlukene zophawu ndawonye. Bagcina ukuhleleka okulungile kanye nesimo sokuhlangana kwezimpawu, baqinisekise ukusebenza kahle.

• Amapuleti endlala: Amapuleti endlala asetshenziselwa ukufaka uphawu emshinini. Basekela ukuhlanganiswa kophawu, balugcine luvikelekile.

• Setha izikulufu: Izikulufu zokusetha ziyizingxenye ezincane, ezinentambo ezisetshenziselwa ukuvikela ukuhlanganiswa kophawu lokusebenza ku-shaft. Baqinisekisa ukuthi isigxivizo sigcina indawo yaso ngesikhathi sokusebenza, sinqanda ukugudluzwa okungase kuphazamise ukusebenza kophawu.

 

 

 

 

Ekuphetheni

Ingxenye ngayinye yophawu lwemishini idlala indima ebalulekile ekuvaleni okusebenzayo kwemishini yezimboni. Ngokuqonda umsebenzi nokubaluleka kwalezi zingxenye, umuntu angabonga ngobunkimbinkimbi nokunemba okudingekayo ekuklameni nasekugcineni izimpawu zemishini ezisebenza kahle.
