ʻO Gasket ka mea e hoʻopaʻa ai i ka mea hoʻololi wela pā. He kuleana koʻikoʻi ia i ka hoʻonui ʻana i ke kaomi sealing a me ka pale ʻana i ka leakage, e hoʻoheheʻe ʻia nā media ʻelua ma kā lākou mau kahawai kahe me ka ʻole o ka hui ʻana.
No laila, he mea nui e hoʻomaopopo i ka hoʻohana ʻana i ka gasket kūpono ma mua o ka holo ʻana i ka mea hoʻololi wela, No laila pehea e koho ai i kahi gasket kūpono nomea hoʻololi wela pā?
ʻO ka mea maʻamau, pono e noʻonoʻo ʻia kēia mau mea:
Inā kūpono ia i ka mahana hoʻolālā;
Inā kūpono ia i ke kaomi hoʻolālā;
ʻO ka hoʻohālikelike kemika no ka media a me ka hoʻomaʻemaʻe CIP;
Paʻa ma lalo o nā kūlana wela kūikawā;
Inā noi ʻia ka papa ʻai
ʻO ka mea gasket maʻamau i hoʻohana ʻia me EPDM, NBR a me VITON, pili lākou i nā mahana like ʻole, kaomi a me ka media.
ʻO ka mahana lawelawe o EPDM he - 25 ~ 180 ℃. He kūpono ia no ka media e like me ka wai, ka mahu, ozone, non petroleum based lubricating oil, dilute acid, weak base, ketone, alcohol, ester etc.
ʻO ka mahana lawelawe o NBR - 15 ~ 130 ℃. He kūpono ia no ka media e like me ka aila wahie, ka aila lubricating, ka aila holoholona, ka aila mea kanu, ka wai wela, ka wai paʻakai etc.
ʻO ka mahana lawelawe o VITON - 15 ~ 200 ℃. He kūpono ia no ka media e like me ka sulfuric acid concentrated, caustic soda, heat transfer oil, alcohol fuel oil, acid fuel oil, high temperature steam, chlorine water, phosphate etc.
Ma keʻano laulā, pono e noʻonoʻo ʻia nā ʻano mea like ʻole e koho i kahi gasket kūpono no ka mea hoʻololi wela pā. Inā pono, hiki ke koho ʻia ka mea gasket ma o ka hoʻāʻo ʻana i ka wai.
