3. Nā ʻano a me ka hoʻohana ʻana omea hoʻopaʻa

ʻO ka mea sila pono e hoʻokō i nā koi o ka hana sila.No ka mea he ʻokoʻa ka media e hoʻopaʻa ʻia a ʻokoʻa nā kūlana hana o nā mea hana, pono nā mea hoʻopaʻa paʻa e loaʻa i nā ʻokoʻa like ʻole.ʻO nā koi no ka hoʻopaʻa ʻana i nā mea maʻamau:

1) He maikaʻi ka nui o ka mea a ʻaʻole maʻalahi ka leak media;

2) Loaʻa i ka ikaika mechanical a me ka paʻakikī;

3) Ka hoʻopili maikaʻi a me ke kūpaʻa, ka liʻiliʻi liʻiliʻi mau loa;

4) ʻAʻole palupalu a palaha paha i nā wela kiʻekiʻe, ʻaʻole paʻakikī a pohā paha i nā wela haʻahaʻa;

5) Loaʻa iā ia ke kūpaʻa corrosion maikaʻi a hiki ke hana no ka manawa lōʻihi i ka waikawa, ka alkali, ka aila a me nā media ʻē aʻe.He liʻiliʻi kona leo a me ka paʻakikī, ʻaʻole pili i ka ʻili metala;

6) Liʻiliʻi friction coefficient a me ka maikaʻi kāʻei pale;

7) Loaʻa iā ia ka maʻalahi e hui pū me kaili hoʻopaʻa;

8) Ke kūpaʻa maikaʻi a me ka lōʻihi;

9) He mea maʻalahi ka hana a me ka hana ʻana, maʻalahi a maʻalahi ka loaʻa ʻana o nā mea.

Lapaʻo ia ka mea hoʻohana maʻamau i hoʻohana ʻia.Ma waho aʻe o ka lāʻau lapaʻau, ʻo nā mea hoʻopaʻa sila kūpono ʻē aʻe he graphite, polytetrafluoroethylene a me nā mea hoʻopaʻa like ʻole.

4. Nā mea pono no ka hoʻokomoʻana a me ka hoʻohanaʻana i nā sila mechanical

1).He ≤0.04 mm ka holo ʻana o ka radial o nā mea hoʻololi a me ka neʻe ʻana o ka axial ma mua o 0.1 mm;

2) Pono e hoʻomaʻemaʻe ʻia ka ʻāpana sealing o nā mea hana i ka wā o ka hoʻokomo ʻana, pono e hoʻomaʻemaʻe ʻia nā ʻāpana hoʻopaʻa ʻana, a paʻa pono ka maka hope o ka sila e pale i nā haumia a me ka lepo mai ka lawe ʻia ʻana i ka ʻāpana sila;

3).ʻAʻole paʻa loa ka paʻi ʻana a kīkēkē paha i ka wā o ke kaʻina hana e pale aku i ka pōʻino friction i ka sila mechanical a me ka pau ʻole o ka sila;

4) I ka wā o ka hoʻokomo ʻana, pono e hoʻopili ʻia kahi papa o ka ʻaila mīkini maʻemaʻe i ka ʻili e pili ana me ka sila e hōʻoia i ka hoʻonohonoho maʻalahi;

5) I ka wā e hoʻokomo ai i ka static ring gland, pono e hoʻoikaika ʻia nā wili paʻa e hōʻoia i ka perpendicularity ma waena o ka maka hope o ke apo static a me ka laina axis;

6) Ma hope o ka hoʻokomo ʻana, e hoʻokuʻu i ke apo neʻe ma ka lima e hoʻoneʻe i ke apo neʻe me ka maʻalahi ma ke kumu a loaʻa kahi pae o ka elasticity;

7) Ma hope o ka hoʻouka ʻana, e hoʻohuli i ka lāʻau ʻōwili ma ka lima.ʻAʻole pono ke kaumaha a me ke kaumaha o ke kumu hoʻololi;

8) Pono e hoʻopiha ʻia nā mea hana me ka media ma mua o ka hana ʻana e pale i ka friction maloʻo a me ka pau ʻole o ka sila;

9) No ka media crystallized a me ka granular maʻalahi, ke ʻoi aku ka mahana ma mua o 80OC, pono e lawe ʻia nā ana e like me ka flushing, kānana, a me ka hoʻoluʻu.E ʻoluʻolu e nānā i nā kūlana kūpono o nā sila mechanical no nā mea kōkua like ʻole.

10).I ka wā o ka hoʻokomo ʻana, pono e hoʻopili ʻia kahi papa o ka ʻaila mechanical maʻemaʻe i ka ʻili e pili ana me kasila.Pono e uku nui ʻia i ke koho ʻana i ka aila mīkini no nā mea hoʻohui like ʻole e pale aku ai i ka hoʻonui ʻana o ka O-ring ma muli o ke komo ʻana o ka ʻaila a i ʻole ka wikiwiki o ka ʻelemakule, e hoʻokau i ka sila mua.He kūpono ʻole.

5. He aha nā mea hoʻopaʻa sila ʻekolu o kahi sila lāʻau mechanical, a me nā loina hoʻopaʻa ʻana o kēia mau mea sila ʻekolu.

ʻO kasilama waena o ke apo neʻe a me ke apo paʻa e hilinaʻi ana i ka mea elastic (punawai, bellows, etc.) a me kawai hoʻopaʻakaomi e hana i ka ikaika kaomi kūpono (ratio) ma ka ʻili pili (ke alo hope) o ke apo e neʻe ana a me ke apo paʻa.ʻO ke kaomi) e hoʻopili pono i nā maka hope ʻelua a pololei;mālama ʻia kahi kiʻiʻoniʻoni wai lahilahi ma waena o nā maka hope e hoʻokō i kahi hopena sila.Loaʻa i kēia kiʻiʻoniʻoni ke kaomi wai a me ke kaomi static, e pāʻani ana i ke ʻano o ke kaupaona ʻana a me ka lubricating i ka maka hope.ʻO ke kumu o ka maʻalahi a me ka pololei o nā maka hope ʻelua, ʻo ia ka hana ʻana i kahi kūpono kūpono no nā maka hope a e hoʻohālikelike i ke kaomi kikoʻī.He sila hoʻololi pili kēia.

6. Sila mīkiniʻike a me nā ʻano ʻenehana seal mechanical

Hiki ke hoʻokaʻawale ʻia ka ʻenehana sealing Bellows i nā bellow metala i hana ʻia a me ka welded metal bellows mechanical sealing technology.

Hoʻokaʻawale ʻia ka ʻenehana sealing multi-end i ʻelua sealing, sealing ring intermediate a me ka ʻenehana multi-seal.Eia kekahi, aia nā ʻenehana sealing surface parallel, nānā ʻenehana sealing, ʻenehana sealing hui, etc.

7. Sila mīkinika ʻike, ka hoʻoheheʻe ʻana i ka sila mechanical a me nā hiʻohiʻona

ʻO ke kumu o ka holoiʻana,ʻo ia ke pale i ka hōʻiliʻiliʻana o nā mea haumia, pale i ka hanaʻana o nāʻeke ea, mālama a hoʻomaikaʻi i ka lubrication, a me nā mea'ē aʻe.ʻO nā ʻano kumu nui o ka flushing penei:

1. ʻO ka ʻili ʻana i loko
