Abavelisi betywina kunye nezinye izinto ezisetyenziswayoipholima(PTFE) ngokukhawuleza ukuba bagqibe ukutshayela uninzi lweengeniso zabo kunye chips machining xa bevelisa iinxalenye ukusuka ngokwesiko ukucinezela iintonga ezibunjiweyo kunye neityhubhu.Iireyini ze-PTFE ziyabiza kwaye zenza iinxalenye ukusuka kuxinzelelo lwentonga ezibunjiweyo okanye iityhubhu zihlala ziphela zivelisa kuphela i-10-20% yezinto ezithengiweyo kwiindawo ezigqityiweyo.Ukusukela ukuba i-PTFE, xa ifakwe i-sintered, ayinakuphinda isetyenziswe kwakhona, i-80% yeendleko zezinto eziphathekayo ziphelela kwinkunkuma.Impendulo kukusebenzisa ubuchule bokubumba i-isostatic ukuvelisa iityhubhu ezibhityileyo ezinodonga.
Ekuqaleni, xa izikhuselo zempumlo ezijulwayo zempumlo zazisenziwa kwi-PTFE, ubuchule babudingeka ukucinezela ngokulinganayo umgubo we-PTFE kumhlaba omile okwembumbulu wekhowuni yempumlo.Oku kwenziwa ngokubeka umgubo we-PTFE phezu kweplagi ye-aluminiyam eyenziwe ngempumlo, emva koko igqume umgubo nge-elastomeric bladder.Iplagi, umgubo kunye nesinyi zaye zafakwa kwisitya soxinzelelo kunye noxinzelelo oluphezulu lwamanzi ampontshelwa ngaphakathi ukuze afezekise ukuxinzelelwa komgubo kwimilo esele yenziwe ngaphambili elungele ukutshisa i-oveni.
Njengenqaku elinomdla elisecaleni, njengoko iirokethi zikhula, kwaye iicones zempumlo zaba nkulu kakhulu ukuba zingene kwiinqanawa zoxinzelelo, iiplagi ezigqunywe sisinyi ezinomgubo wentlaka ngaphakathi zathotywa nje elwandle ukuya kubunzulu obufanelekileyo ukufikelela kuxinzelelo olufanelekileyo loxinzelelo.
I-isostatic yanamhlanjeoomatshini bokubumbabasuka kude ukusuka kwikhowuni yempumlo ejulwayo.Ngoku basebenzisa ioli endaweni yamanzi kwiinqanawa zoxinzelelo lwe-cylindrical.Oomatshini bokubumba i-Isostatic ngokubanzi basebenzisa inkqubo yoxinzelelo lwe-hydraulic etyisa umxhasi wesiko ukukhaba uxinzelelo olusuka kumalungu esiqhelo angama-3000 wenkqubo yoxinzelelo lwe-psi ukuya kuxinzelelo oluphezulu olufunekayo ukufezekisa iipropati ezifanelekileyo zomzimba kwi-PTFE ebunjiweyo.
Uyilo olungcono lusebenzisa i-mandrels etshintshanayo ukwenza iyunithi iqhelane nobukhulu obuninzi betyhubhu, kunye ne-polyurethane ekupheleni kunye neefom zedayamitha zangaphandle zokudlulisa uxinzelelo lwe-hydraulic ukusuka kwisinyi se-urethane ukuya kwiisayizi ezahlukeneyo zetyhubhu.I-urethane ethambileyo isebenza njengolwelo ngokwalo ukudlulisa uxinzelelo lwehydraulic kwintlaka engumgubo exiniweyo.Ngokusebenzisa iintsimbi ezithambileyo zokuphela, ukubethelwa kokuphela okuqhelekileyo kunye noyilo lwangaphambili kucinywa ukuze bonke ubude bombhobho obunjiweyo busebenziseke.
Ulawulo oluncinci lwe-hydraulic luyafuneka, kwaye uninzi lwamalungu olwelo olwenziwa ngamanzi afunekayo ayafumaneka ngaphandle kweshelufu.Imeko eyahlukileyo sisigxininisi, ekufuneka siqhele ukuyilwa ukusuka ekuqaleni ukuphumeza unyuso olufunekayo loxinzelelo kunye neemfuno zokwenziwa komthamo wenkqubo enkulu, ebhetyebhetye yehydraulic.
