Phakathi kwezinto ezininzi zokutywina, "o" uhloboI-Seal ringHn 7445-200 × 7.0 isetyenziswe ngokubanzi kwimimandla eyahlukeneyo yeshishini ngenxa yokusebenza kwabo ngokugqibeleleyo kunye nokunyaniseka. Eli nqaku liza kugxila kwinkcazo ethile ye-o-ring-ring 7445-250 × 7.0, kwaye ixoxe ngezinto zayo, isakhiwo, imeko yesicelo kunye nezibonelelo.

I-O-ring HN 7445-250 × 7.0 yenziwe ngerabha yerabha (i-nbr) kunye ne-nitrile irabha. Esi sixhobo sinokuchasana kweoyile elungileyo, ukumelana nokuziphatha nokunganyangeki, kwaye kufanelekile ukuba ube ziindawo ezahlukeneyo kunye nemithombo yeendaba. Ipropathi entle yerabha ye-nitrile ivumela i-HN 7445-200-200 × 7.0 O

I-o-ring yirhasi ye-ring ene-rain, kunye ne-onnastomer ye-elastomer kunye noyilo lwecandelo lokuwela i-candelo livumela ukuba libekwe kwi-Groove kwaye licinezelwe ngamacandelo amabini okanye ngaphezulu kwendibano. Olu lwakhiwo olulula nolukaci olukhulu lwenza i-o-ring enye yeyona uyilo luxhaphakileyo lokutywinwa.

Ubungakanani be "O" khupha itywina HN 7445-250 × 7.0 yi-250 × 70 mm kunye nenqanaba le-Pros-Cross yi-7.0 mm. I-o-rings yolu nkcazo inokumelana noxinzelelo lwe-pascals yeshumi elinambini (amawaka eepawundi), ibenza balungele iindawo ezahlukeneyo zoxinzelelo.

Ngokwezicelo, i-HN 7445-250-200 × 7.0 I-O-iringi inokusetyenziswa kwizicelo ezichongiweyo, ezinje ngezikhongozeli zokutywina, imibhobho kunye neevalve. Ingasetyenziswa kwizicelo ezinamandla apho kukho intshukumo ephakathi kwamacandelo, enjenge-shaft yempompo yeposti kunye nepiston ye-hydraulic cylicter. Kwezi zicelo, iringi ye-O inokuthintela ngempumelelo ukuvuza okuphakathi kwaye kuqinisekiswe ukusebenza kwesiqhelo kwezixhobo.

Ukulula kwemveliso, iindleko eziphantsi, ezilula zokufakwa, kunye nomsebenzi othembekileyo weIringiyenza ukuba ihlawulwe kakhulu kwicandelo lokutywinwa kwemizi-mveliso. Xa kuthelekiswa nezinye izinto zokutywina, ufakelo kunye neendleko zokugcina i-O-iringi ephantsi kwaye kulula ukuyibuyisela.

Nangona kunjalo, kubalulekile ukuba uqaphele ukuba nangona i-O-iringi ineendleko eziphezulu, kusafuneka ukuba ukhethe ngokwesimo sefowuni kunye neemfuno xa ukhetha. Umzekelo, amajelo osasazo, amaqondo obushushu, kunye neengcinezelo zineemfuno ezahlukeneyo zezinto kunye nobungakanani be-o-ring. Ke ngoko, xa uthenga i-o-ring, qiniseka ukuba uqinisekisa ukuba inkcazo ekhethiweyo kunye nezinto ezinokufezekisa iimfuno zokwenyani.

Kwisishwankathelo, "O" uhlobo lokuthengiswa kwetywina HN 7445-250 × 7.0, Ulwakhiwo olungenantlonelo, lunomyinge ongenayo, inomyinge ophethwe yindleko kwicandelo lokutywina kwemveliso. Ukukhetha ngokuchanekileyo kunye nokufakwa kwe-O-iringi inokuqinisekisa ukusebenza kwesiqhelo kwezixhobo kwaye kwandiswe ubomi benkonzo. KuPhuhliso lweMizi-mveliso yexesha elizayo, i-HN 7445-250-209-20 × 7.0 I-O-iringi iza kuqhubeka nokudlala indima yayo ebalulekileyo kwaye ibonelele ngokhuseleko olunokuthenjwa kwizixhobo ezahlukeneyo kunye neenkqubo.
