yazi umehluko phakathi kwe-single and double mechanical seal

I-Ningbo Xindeng Seals ihamba phambiliuphawu lomshiniumphakeli eningizimu ye-china, kusukela ngo-2002, asigxili kuphela ekwenzeni zonke izinhlobo ze-mechanical seal, kodwa futhi sinake ukuthuthukiswa kobuchwepheshe bezimpawu zemishini.

Sivame ukuxoxa nonjiniyela othile omkhulu ku-mechanical seal efakiwe, futhi sazi isibuyekezo se-seals tech.

Ngezansi i-athikili kunefayela lobuchwepheshe elihle lokwazi ukuthi yimuphi umehluko mayelana ne-single mechanical seal kanye ne-double mechanical seal, sabelana ngale dokhumenti ukuze sazise abantu abaningi.

Ama-mechanical seal amadivaysi avala imishini phakathi kwezingxenye eziphendukayo (shaft) kanye nezingxenye ezimile (indlu yamaphampu) futhi ayingxenye ebalulekile yepompo.Umsebenzi wabo oyinhloko ukuvimbela umkhiqizo ompontshelwe ukuthi ungangeni endaweni ezungezile futhi ukhiqizwa njengezimpawu ezilodwa noma ezimbili.Uyini umehluko phakathi kwakho kokubili?

IYINI I-MECHANICAL SEAL EYODWA?

Uphawu olulodwa lomshini luqukethe izindawo ezimbili eziyisicaba kakhulu ezicindezelwa ndawonye isiphethu bese zishelelana.Phakathi kwalezi zindawo ezimbili kukhona ifilimu ewuketshezi ekhiqizwa umkhiqizo ompontshiwe.Le filimu ewuketshezi ivimbela uphawu olusetshenziswayo ukuthi luthinte iringi emile.Ukungabikho kwaleli filimu eliwuketshezi (ukusebenza okomile kwepompo) kubangela ukushisa okungqubuzanayo kanye nokucekelwa phansi komshini wophawu.

Izigxivizo zemishini zivame ukuvuza umhwamuko ukusuka ohlangothini lwengcindezi ephezulu iye ohlangothini lwengcindezi ephansi.Lolu ketshezi lugcoba ubuso be-seal futhi lumunce ukushisa okubangelwa ukungqubuzana okuhlobene, okunqamula ubuso be-seal njengoketshezi bese kuhwamuka emoyeni.Ngakho-ke, kuwumkhuba ojwayelekile ukusebenzisa uphawu olulodwa lomshini uma umkhiqizo ompontshiwe ubeka engcupheni encane endaweni ezungezile.

IYINI I-DOUBLE MECHANICAL SEAL?

I-double mechanical seal iqukethe izigxivizo ezimbili ezihlelwe ngochungechunge.I-inboard, noma "primary seal" igcina umkhiqizo uqukethwe ngaphakathi kwendlu yephampu.I-outboard, noma "seal seal" ivimbela uketshezi olushaywayo ukuthi lungangeni emkhathini.

Isigxivizo esiphindwe kabili semishini

emuva emuva

ubuso nobuso

usebenzisa izigxivizo ezimbili.

Single mechanical seal

ingxenye eyodwa yendandatho ye-rotary

eyodwa staionary ring ingxenye.

enengxenye yesibili yophawu, njengerabha, ptfe, fep

 

Izigxivizo ezimbili ezisebenza ngomshini zinikezwa ngamalungiselelo amabili:

• Emuva emuva
  • Amandandatho amabili ajikelezayo ophawu ahlelwa abheke kude.Ifilimu yokugcoba ikhiqizwa uketshezi oluvimbelayo.Leli lungiselelo livame ukutholakala embonini yamakhemikhali.Uma kwenzeka ukuvuza, uketshezi oluvimbelayo lungena emkhiqizweni.
• Ubuso nobuso
  • Ubuso be-rotary seal obulayishwe intwasahlobo buhlelwa bubheke ubuso nobuso bese bushelela busuka kolunye uhlangothi buyiswe engxenyeni eyodwa noma ezimbili ezimile.Lokhu ukukhetha okudumile embonini yokudla, ikakhulukazi emikhiqizweni evame ukunamathela.Uma kwenzeka ukuvuza, uketshezi oluvimbelayo lungena emkhiqizweni.Uma umkhiqizo ubhekwa "ushisayo", uketshezi oluvimbelayo lusebenza njenge-ejenti yokupholisa uphawu lwemishini.

Izigxivizo ezimbili ezisebenza ngomshini zivame ukusetshenziswa ezimweni ezilandelayo:

• Uma uketshezi nezihwamuko zalo kuyingozi ku-opharetha noma endaweni, futhi KUMELE kuqukethwe
• Lapho imidiya enolaka isetshenziswa lapho kunengcindezi ephezulu noma amazinga okushisa
• Okwemidiya eminingi ye-polymerizing, enamathelayo
