yazi umahluko phakathi kwetywina elinye kunye neliphindwe kabini lomatshini

INingbo Xindeng Seals iphambiliitywina lomatshiniumthengisi osemazantsi e-china, ukususela ngo-2002, asigxininisi kuphela ekwenzeni zonke iintlobo ze-mechanical seal, kodwa sinikele ingqalelo ekuphuculweni kobugcisa bokutywinwa komatshini.

Sihlala sixoxa kunye nenjineli ethile ephezulu kwitywina lomatshini elifakwe, kwaye sazi uhlaziyo lwetekhnoloji yetywina.

Ngezantsi inqaku ifayile yetekhnoloji elungileyo yokwazi ukuba yintoni umahluko malunga netywina lomatshini elinye kunye netywina eliphindwe kabini lomatshini, sabelana ngolu xwebhu ukwazisa abantu abaninzi ngalo.

Mechanical seals zizixhobo ezitywina oomatshini phakathi kwamalungu ajikelezayo (iishafti) kunye neendawo ezimileyo (izindlu zempompo) kwaye ziyinxalenye yempompo. Umsebenzi wabo ophambili kukuthintela imveliso emponthiweyo ekuvuzeni kokusingqongileyo kwaye yenziwa njengetywina elinye okanye kabini. Yintoni umahluko phakathi kwezi zimbini?

YINTONI Itywina ELINYE LOOMATSHINI?

Isitywina esisebenza ngoomatshini sinemigangatho emibini ethe tyaba ecinezelwe kunye ngespring kunye nesilayidi ngokuchaseneyo. Phakathi kwale miphezulu mibini kukho ifilimu yolwelo eyenziwe yimveliso emponthiweyo. Lo mboniso bhanyabhanya wolwelo unqanda itywina lomatshini ekubambeni iringi emileyo. Ukungabikho kwale filimu yolwelo (ukusebenza okomileyo kwempompo) kubangela ubushushu obukhukhulayo kunye nokutshatyalaliswa kokugqibela kwetywina lomatshini.

Iimpawu zoomatshini zikholisa ukuvuza umphunga ukusuka kwicala loxinzelelo oluphezulu ukuya kwicala loxinzelelo oluphantsi. Olu lwelo luthambisa ubuso betywina luze lufunxe ubushushu obuveliswa kukukhuhlana okunxulumene noko, obunqumla ubuso betywina njengolwelo luze lube ngumphunga emoyeni. Ke, yinto eqhelekileyo ukusebenzisa itywina elinye lomatshini ukuba imveliso emponthiweyo ayibeki mngcipheko omncinci kokusingqongileyo.

Ngaba ufuna ulwazi oluninzi lwangaphakathi oluvela kubuNjineli beCrane?

YINTONI I-DOUBLE MECHHANICAL SEAL?

Itywina eliphindwe kabini lomatshini liquka amatywina amabini acwangciswe ngokulandelelana. I-inboard, okanye "i-primary seal" igcina imveliso equlethwe ngaphakathi kwendlu yempompo. I-outboard, okanye "itywina lesibini" lithintela ulwelo olugungxulwayo ukuba lungavuzi emoyeni.

Izitywina eziphindwe kabini zoomatshini zinikezelwa ngamalungiselelo amabini:

• Umva nomva
  • Amakhonkco amabini ajikelezayo okutywina acwangciswe ajonge kude omnye komnye. Ifilimu yokuthambisa iveliswa ngulwelo lwesithintelo. Eli lungiselelo lidla ngokufumaneka kwishishini lemichiza. Kwimeko yokuvuza, ulwelo lomqobo lungena kwimveliso.
• Ubuso ngobuso
  • Ubuso betywina obulayishwe entwasahlobo bucwangciswe ubuso ngobuso kwaye butyibilika ukusuka kwelinye icala ukuya kwindawo enye okanye ezimbini ezimileyo. Olu lukhetho oludumileyo kwishishini lokutya, ngakumbi kwiimveliso ezithanda ukuncamathela. Kwimeko yokuvuza, ulwelo lomqobo lungena kwimveliso. Ukuba imveliso ithathwa "ishushu", i-barrier barrier liquide yenza njenge-agent epholileyo yesitywina somatshini.

Iitywina eziphindwe kabini zoomatshini ziqhele ukusetyenziswa kwezi meko zilandelayo:

• Ukuba ulwelo kunye nomphunga walo unobungozi kumsebenzisi okanye kwindawo engqongileyo, kwaye KUFUNEKA lugcinwe
• Xa imidiya enobudlova isetyenziselwa uxinzelelo oluphezulu okanye amaqondo obushushu
• Kwiipolymerizing ezininzi, imidiya encangathi
