Chidziwitso choyambirira cha makina a hydraulic ndi zisindikizo zamapampu

Chosindikiziracho chimapangidwa ndi sitepe ndi O-ring.
Kuchita ndi kudalirika kwa makina a hydraulic ndi mapampu kumadalira kwambiri momwe zisindikizo zimagwirira ntchito, zomwe piston rod seal ndi piston seal ndi zida zosindikizira.Zisindikizo zophatikizira masitepe (zisindikizo zamasitepe kuphatikiza zisindikizo za O-ring) ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi piston rod ndipo zimagwiritsidwanso ntchito posindikiza pisitoni.
Makina a Hydraulic ndid mpope pophatikizira masitepe osindikiza mawonekedwe ake:

Zisindikizo za pistoni za Hydraulic zosindikizira masitepe

1. Kupanikizika ≤(MPa) : 60/MPa
2. Kutentha: -45 ℃ mpaka +200 ℃
3. Liwiro ≤(m/s) : 15 m/s
4. Zida zosindikizira: NBR/PTFE FKM
5. Amagwiritsidwa ntchito makamaka mu: pisitoni ndodo mu makina a hydraulic, silinda yokhazikika, chida cha makina, makina osindikizira a hydraulic, etc.

Monga chida chosindikizira chachikulu monga piston rod seal ndi piston seal, ngati pali kutayikira, zidzakhudza momwe makinawo amagwirira ntchito ndikuwononga chilengedwe.Chifukwa chake, chisindikizo chophatikizika chophatikizika osati pansi pazisindikizo zokhazikika (static), komanso pansi pazisindikizo zokhazikika (zamphamvu) ndizotheka kukwaniritsa kutayikira kochepa.
Kuphatikiza apo, kugwiritsa ntchito mphamvu zamagetsi komanso kuvala kwa zida zosindikizira kumakhudzanso kwambiri magwiridwe antchito amakina.Kutayikira, kugwiritsa ntchito mphamvu, kuvala moyo ndi zina zofunika kwambiri za chisindikizo chophatikizika komanso mawonekedwe amakina a chisindikizo pansi pamikhalidwe yogwirira ntchito ndizogwirizana kwambiri ndi kukakamizidwa ndi kugawa kwa malo olumikizana pakati pa chisindikizo ndi ndodo ya pistoni (kapena khoma la silinda). ).Ndi za chikoka cha mawotchi dongosolo ntchito magawo pa makina katundu ndi ntchito zisindikizo.
