ʻO ka loina hoʻopaʻa ʻana o ka paʻi ʻana e hilinaʻi nui ʻia i ka hopena labyrinth a me ka hopena o ka lawe ʻana.

ʻO ka hopena Maze: ʻAʻole kūlike ka ʻili o ka microscopic i lalo o ka lāʻau, a hiki ke kūpono i kahi ʻāpana me ka paʻi, akā ʻaʻole pili me nā ʻāpana ʻē aʻe. No laila, aia kahi ʻāpana liʻiliʻi ma waena o ka paʻi ʻana a me ke kumu, e like me ka maze, a ʻo ke ʻano kaomi i loko o ke āpau. Hoʻopili ʻia i nā manawa he nui e hoʻokō i ka hopena sealing.

Ka hopena: E loaʻa kahi kiʻiʻoniʻoni wai liʻiliʻi ma waena o ka paʻi a me ke kumu, ka mea e hoʻohālikelike ai i ka paʻi ʻana a me ke kumu i nā bearings sliding a pāʻani i kekahi hopena lubrication, no laila e pale aku ai i ka ʻaʻahu nui o ka paʻi a me ke kumu.

Nā mea e pono ai ka hoʻopaʻa ʻana: Ma muli o ka mahana, ke kaomi, a me ka PH o ka mea i hoʻopaʻa ʻia, a me ka wikiwiki laina, ka ʻili o ka ʻili, coaxiality, runout radial, eccentricity a me nā mea ʻē aʻe o ka axially. pahu moku ʻO ka pauma, pono e loaʻa i nā mea packing nā ʻano penei:

1. Loaʻa i kekahi degere o ka elasticity a me ka plasticity

2. Ke kūpaʻa kemika

3. Impermeability

4. Lubrication pono'ī

5. Kū'ē wela

6. Maʻalahi e wehe a hui

7. Maʻalahi e hana a haʻahaʻa i ke kumukūʻai.

Hoʻopili pololei nā mea waiwai i luna i ka hana sila a me ke ola lawelawe o ka paʻi ʻana, a he liʻiliʻi loa nā mea hiki ke hoʻokō piha i nā waiwai āpau i luna. No laila, ʻo ka loaʻa ʻana o nā mea hoʻopaʻa kiʻekiʻe kiʻekiʻe a me ka hoʻomaikaʻi ʻana i kā lākou mau waiwai waiwai ʻo ia ka mea nui o ka noiʻi ʻana ma ke kahua o ka sila.

Hoʻokaʻawale, haku mele ʻana a me ka hoʻohana ʻana i ka paʻi ʻana no  axially split case pumps .

Ma muli o nā kūlana hana like ʻole, nui nā ʻano mea packing. I mea e hoʻokaʻawale maikaʻi ai a koho i ka hoʻopili ʻana, hoʻokaʻawale pinepine mākou i ka paʻi ʻana e like me ka mea o ka mea kumu kumu hoʻopaʻa hoʻopaʻa paʻa:

1. Hoʻopili fiber maoli. ʻO ka pulupulu maoli, ke olonā, ka hulu hipa, a me nā mea ʻē aʻe, e like me ka hoʻopaʻa ʻana i nā mea kumu.

2. Hoʻopili ʻana i ka fiber mineral. ʻO ka hoʻopili ʻana i ka fiber mineral ka nui o ka asbestos packing, etc.

3. Hoʻopili fiber synthetic. ʻO ka hoʻopili ʻana i ka fiber synthetic ka mea nui: graphite packing, carbon fiber packing, PTFE packing, Kevlar packing, acrylic-clip silicone fiber packing, etc.

4. Hoʻopili ʻia ka pāpaʻi a me ka fiber Metala ʻo ka hoʻopaʻa ʻana i nā mea nui: silicon carbide packing, boron carbide packing, medium-alkali glass fiber packing, etc. hoʻohana ʻia ka fiber no ka ulana ʻana i ka ʻeke. No ka mea aia nā āpau ma waena o nā fiber packing, maʻalahi ke kumu leakage. I ka manawa like, loaʻa i kekahi mau fibers nā waiwai lubricating ponoʻī a me kahi coefficient friction nui, no laila pono lākou e hoʻopili ʻia me kekahi mau lubricants a me nā mea hoʻopihapiha. a me nā mea hoʻohui kūikawā, etc. No ka hoʻomaikaʻi ʻana i ka momona a me ka lubricity o ka mea hoʻopihapiha, e like me: ka aila mineral a i ʻole ka molybdenum disulfide grease i hui pū ʻia me ka pauka graphite, talc pauka, mica, glycerin, ʻaila ʻaila, etc., a impregnated polytetrafluoroethylene dispersion emulsion, a i Hoʻohui i nā nui kūpono o nā surfactants a me nā mea hoʻopuehu i ka emulsion. Hoʻokomo pinepine ʻia nā mea hoʻohui kūikawā i nā ʻāpana zinc, nā mea pale, nā mea hoʻopiʻi corrosion e pili ana i ka molybdenum, etc.
