Hordhac Aqoonta Seal ee ugu Fahamsan.

Saliidda saliidda waa qayb makaanik ah oo loo isticmaalo xiridda, oo sidoo kale loo yaqaan giraanta shaabada bishimaha ee wareega.Qaybta is jiid jiidka ee mishiinada waxa laga ilaaliyaa in saliida soo gasho inta lagu guda jiro shaqada, iyo shaabada saliidda ayaa loo isticmaalaa si looga hortago in saliidda ee mishiinka.Kuwa caadiga ah waa saliidaha qalfoofka.

1. Habka matalida shaabadda saliidda

Hababka matalaadda guud:

Nooca shaabadda saliidda - dhexroorka gudaha - dhexroorka dibadda - dhererka - walxaha

Tusaale ahaan, TC30 * 50 * 10-NBR waxay ka dhigan tahay shaabad saliideed oo labajibbaaran oo gudaha ah oo leh dhexroor gudaha ah oo ah 30, dhexroorka dibadda ah 50, iyo dhumucda 10, oo ka samaysan caag nitrile ah.

2. Qalabka saliidda qalfoofka

Nitrile caag (NBR): xidho adkaysi u leh, saliid adkaysi (lama isticmaali karo warbaahinta polar), heerkulka u adkaysta: -40 ~ 120 ℃.

Caag Nitrile Hydrogenated (HNBR): Xiro caabbinta, caabbinta saliidda, caabbinta gabowga, caabbinta heerkulka: -40 ~ 200 ℃ (ka xoog badan iska caabinta heerkulka NBR).

Xabagta Fluorine (FKM): aashitada iyo alkali adkaysi u leh, saliid adkaysi u leh (u adkaysta dhammaan saliidaha), heerkulka u adkaysta: -20 ~ 300 ℃ ( iska caabin saliid ka wanaagsan labada sare).

Rubber Polyurethane (TPU): Xiro iska caabbinta, iska caabinta gabowga, iska caabinta heerkulka: -20 ~ 250 ℃ ( iska caabin gabow heer sare ah).

Caag Silikoon ah (PMQ): kulayl u adkaysta, qabow u adkaysta, oo leh cidhiidhi yar oo qallafsan oo joogto ah iyo xoog farsamo oo hooseeya.Iska caabinta heerkulka: -60 ~ 250 ℃ (iska caabin heerkul aad u fiican).

Polytetrafluoroethylene (PTFE): waxay leedahay xasillooni kiimiko oo wanaagsan, iska caabin u ah warbaahinta kala duwan sida aashitada, alkali, iyo saliidda, xidho caabbinta iyo iska caabbinta heerkulka sare, xoogga farsamada sare, iyo sifooyinka wanaagsan ee is-saliimaynta.

Guud ahaan, alaabta sida caadiga ah loo isticmaalo shaabada saliidda qalfoofka waa caag nitrile, fluororubber, caag silikoon, iyo polytetrafluoroethylene.Sababtoo ah sifooyinka wanaagsan ee is-saliimaynta, gaar ahaan marka lagu daro bronze, saameyntu way ka sii fiican tahay.Dhammaantood waxaa loo isticmaalaa in lagu sameeyo faraanti haynta, giraangiraha Glee, iyo sticks.

3. Kala saarida qaabka qalfoofkasaliid xidhid

Shaabadda saliidda qalfoofka nooca C-ga waxaa loo qaybin karaa shan nooc: Nooca shaabadda saliidda ee SC, nooca shaabadda T Coi, nooca shaabadda saliidda ee VC, nooca saliidda KC, iyo nooca saliidda DC.Waxay yihiin shaabaddii saliidda qalfoofka ee bushimaha gudaheed, shaabad saliideed oo labajibbaaran, shaabad saliid gudaha ah oo bilaash ah, bushimo labajibbaaran oo saliid gudaha ah oo bilaash ah, iyo shaabad saliid gudaha ah oo bilaash ah.(Waxaan kugula talineynaa inaad fiiro gaar ah u yeelato xisaabta rasmiga ah "Injineer Makaanik" si aad u fahamto aqoonta alaabta qalalan iyo macluumaadka warshadaha marka ugu horeysa)

Shaabadda saliidda qalfoofka ee nooca G waxay leedahay qaab dun ah oo dibadda ah, kaas oo la mid ah nooca C-ga.Si kastaba ha ahaatee, waxaa la bedelay si ay u leedahay qaab dunta dibadda ee habka, oo la mid ah shaqada aO-ring, taas oo aan kor u qaadin saamaynta xidhitaanka, laakiin sidoo kale waxay ka caawisaa hagaajinta saliidda saliidda ee dabacsan.

Shaabadda saliidda qalfoofka ee nooca B waxay leedahay walxo xabag ah oo ku yaal dhinaca gudaha ee qalfoofka ama ma jiraan wax dhejis ah gudaha ama dibedda qalfoofka.Maqnaanshaha walxaha koollada ayaa hagaajin doona waxqabadka kulaylka.

Shaabadda saliidda A-nooca qalfoofka waa shaabad la soo ururiyey oo leh qaab-dhismeed aad u adag marka la barbar dhigo saddexda nooc ee kor ku xusan, oo lagu garto waxqabadka cadaadiska ka wanaagsan oo sarreeya.
