Muhuri wa Silinda ya Nyumatiki ya ZHM
♠Maelezo-ZHM Pneumatic Seal
Muhuri wa Nyuma wa ZHM unaotumika kwa vijiti vya silinda vinavyofanana kwa kuziba na kuzuia vumbi, nyingi zikitumia FKM/VITON na nyenzo za silikoni.Mdomo wa kuziba ulioimarishwa umeundwa mahsusi kwa ajili ya utumizi wa kuziba kwa fimbo ya silinda.Kando na hilo, mwelekeo wa kuziba muhuri wa nyumatiki unaweza kuwa wa ndani kama kwa muhuri wa fimbo, wa nje kama kwa bastola, ulinganifu, au axial.Kwa mihuri ya ndani ya nyumatiki, shimo la nyumba huzunguka muhuri na mdomo wa kuziba hugusa shimoni.Kwa kuongeza, muhuri huu unahitaji lubricant kidogo sana.

♣Faida
● Sifa za umeme, PTFE ni nyenzo isiyo ya polar, yenye sifa bora sana za dielectri, hasa ikiwa ni zaidi ya 0 ℃, sifa za dielectric na haiathiri mzunguko wa joto, unyevu na haiathiriwi na gesi babuzi .PTFE kiasi resistivity na uso resistivity ni ya juu zaidi ya plastiki zote, hata baada ya kuzamishwa kwa muda mrefu katika maji, itakuwa si kushuka kwa kiasi kikubwa, katika 100% unyevu wa hewa, resistivity uso bado unchanged.Ufuwele wa PTFE kwa 50% hadi 80%, nguvu ya dielectri ni karibu huru ya kiwango cha fuwele, na kuwa na dielectric ya chini kabisa isiyobadilika.PTFE upinzani bora wa safu.
