ZHM pnevmatik muhr Pnevmatik silindrli muhr
♠Ta'rif-ZHM pnevmatik muhr
ZHM pnevmatik plomba muhrlash va changdan himoya qilish uchun pistonli silindrli novdalar uchun ishlatiladi, ularning aksariyati FKM / VITON va silikon materialdan foydalanadi.Qalinlashgan sızdırmazlık dudog'i silindrli novda muhrlash ilovalari uchun maxsus mo'ljallangan.Bundan tashqari, pnevmatik muhrning muhrlanish yo'nalishi novda muhridagi kabi ichki, pistonli kabi tashqi, simmetrik yoki eksenel bo'lishi mumkin.Ichki pnevmatik qistirmalari bilan korpus teshigi muhrni o'rab oladi va muhrlangan labda milga tegadi.Bunga qo'shimcha ravishda, bu muhr juda kam yog'ni talab qiladi.

♣ Afzallik
● Elektr xususiyatlari, PTFE juda qutbsiz material bo'lib, juda zo'r dielektrik xususiyatlarga ega, 0 ℃ dan yuqori bo'lsa, dielektrik xususiyatlarga ega va harorat, namlik bilan chastotaga ta'sir qilmaydi va korroziy gaz ta'siriga duchor bo'lmaydi.PTFE hajmining qarshiligi va sirt qarshiligi barcha plastmassalardan eng yuqorisidir, hatto suvga uzoq vaqt botgandan keyin ham u sezilarli darajada pasaymaydi, havoning 100% nisbiy namligida sirt qarshiligi o'zgarishsiz qoladi.PTFE ning kristalliligi 50% dan 80% gacha, dielektrik quvvati kristallik darajasidan deyarli mustaqil va eng past dielektrik o'tkazuvchanlikka ega.PTFE mukammal yoy qarshiligi.
