Imaphi amafutha ongawasebenzisa kuma-o-ring werabha we-hose

Uma kuziwa ekugcineni ukusebenza nokuphila isikhathi eside kwama-o-ring werabha wamapayipi, ukusebenzisa amafutha afanele kubalulekile. Igrisi isebenza njengesithiyo esivikelayo, inciphisa ukungqubuzana, ivimbele ukuguga, futhi iqinisekise ukuvaleka okusebenzayo. Kodwa-ke, ngezinketho eziningi ezitholakalayo emakethe, ukukhetha amafutha afanele kungaba nzima. Kulesi sihloko, sizohlola izinhlobo ezahlukene zamafutha afanele ama-o-rings enjoloba, izici zawo, kanye nokusetshenziswa kwazo. Ukwengeza, sizoxoxa ngezinzuzo zokusebenzisa amafutha, amasu okusebenzisa afanele, namathiphu okunakekela ukuze kuthuthukiswe ukusebenza kwama-o-rings erabha.

1. Ukubaluleka Kokukhetha Igrisi Elungile

Ukuthambisa okufanele kubalulekile ukuze ama-o-rings erabha asebenze kahle. Igrisi elungile ayigcini nje ngokuthuthukisa ukusebenza kokuvala kodwa futhi ivikela umswakama, ukugqwala, nokuwohloka okubangelwa izici zangaphandle. Iqinisekisa ukunyakaza okushelelayo kwama-o-rings, kunciphisa ukungqubuzana futhi kuwavimbele ekubeni ome, aqhekeke, noma abe brittle.

2. I-Silicone Grease: Iguquguquka futhi Imelana Nokushisa

Igrisi eyodwa evame ukusetshenziswa kuma-o-rings enjoloba igrisi ye-silicone. Kuyi-lubricant eguquguqukayo enokumelana okuhle kakhulu namazinga okushisa aphezulu, asukela ku -40ºC kuya ku-200ºC (-40ºF kuya ku-392ºF). Igrisi ye-Silicone ihambisana kakhulu nerabha futhi inikeza ukuxosha amanzi okuphakeme. Ivala ngokuphumelelayo umswakama nokungcola, ikwenze ifaneleke izinhlelo zokusebenza ezichayeka ezimweni ezinzima zemvelo, njengezimoto, zasolwandle, namapayipi.

3. Amafutha Asekelwe Kuphethiloli: Ayabiza Futhi Atholakala Ngokugcwele

Amafutha asuselwa ku-petroleum, abuye abizwe ngokuthi ama-mineral oil-based greases, ayizinketho ezingabizi kakhulu ezitholakala kabanzi emakethe. Lawa mafutha ahlinzeka ngezakhiwo ezinhle zokuvala, ukuhambisana nerabha, nokumelana nezinga lokushisa okulingene. Zivame ukusetshenziswa ezinhlobonhlobo zezimboni lapho izinga lokushisa elidlulele noma ukumelana namakhemikhali kungadingeki.

4. Amafutha AFluorinated: Ukumelana Namakhemikhali Okukhethekile

Amafutha ane-fluorinated, afana namafutha e-perfluoropolyether (PFPE), anikeza ukumelana kwamakhemikhali okukhethekile kanye nokuzinza kokushisa. Lawa mafutha avame ukusetshenziswa ezimbonini ezidinga amandla, okuhlanganisa i-aerospace ne-electronics, lapho ukuchayeka kumakhemikhali anokhahlo, izincibilikisi namazinga okushisa aphakeme kuvamile. Amafutha aFluorinated anebanga lokushisa elibanzi lokusebenza, ngokuvamile elisukela -70ºC ukuya ku-250ºC (-94ºF ukuya ku-482ºF).

5. Ukucabangela Ukuhambisana: Indima Yokubunjwa Kwenjoloba

Ngenkathi kukhethwa igrisi efanelekile, kubalulekile ukucabangela ukuhambisana phakathi kwamafutha kanye ne-rubber o-ring material. Izinhlanganisela zenjoloba ezihlukene, njenge-silicone, i-nitrile, noma i-EPDM, zingase zibe nokuhambisana okuhlukile namagrisi athile. Bheka imihlahlandlela yomkhiqizi noma wenze izivivinyo zokuhambisana ukuze uqinisekise ukuthi amafutha akhethiwe awabangeli ukuvuvukala, ukuncipha, noma ukuwohloka kwama-o-rings erabha.

Amasu okusebenza afanelekile:

Ukufaka amafutha kuma-o-rings enjoloba kuyinqubo elula edinga ukunakwa ngemininingwane. Landela lezi zinyathelo ukuze uthole imiphumela emihle:

1. Hlanza I-O-Ring: Ngaphambi kokufaka amafutha, qiniseka ukuthi i-o-ring yerabha ayinakho ukungcola, imfucumfucu, nanoma yiziphi izinto zokugcoba ezindala. Sebenzisa okokugeza okuthambile noma okokuncibilikisa ukuhlanza i-o-ring kahle. Hlanza ngamanzi bese uvumela ukuthi wome ngokuphelele ngaphambi kokuqhubeka.

2. Gcoba Ungqimba Oluncane: Usebenzisa indwangu ehlanzekile, engenantambo, gcoba ungqimba lwamafutha oluncane olulinganayo ebusweni be-o-ring yerabha. Gwema ukunqwabelana kwamafutha amaningi, njengoba kungaheha ukungcola okuningi futhi kuphazamise ukusebenza. Qinisekisa ukuthi igrisi ivala yonke isiyingi se-o-ring.

3. Gwema I-Silicone Grease ku-EPDM: Nakuba amafutha e-silicone ehambisana nama-o-ring amaningi eraba, akufanele asetshenziswe kuma-o-rings enziwe nge-EPDM (ethylene propylene diene monomer). I-EPDM inezinga eliphezulu lokumunca uwoyela, okuholela ekuvuvukeni nasekuwohlokeni lapho kuvezwe amafutha abicah.

4. Cabangela Isivinini Nokucindezela: Ezinhlelweni zejubane eliphezulu noma lezo ezibandakanya ukucindezela okukhulu, sebenzisa izithambisi ezikhelwe ngokukhethekile izimo ezinjalo. Lawa mafutha ngokuvamile anezithasiselo zokuthuthukisa ukusebenza ngaphansi kwemithwalo enzima kakhulu.

5. Ukuhlola Okuvamile Nokugcoba Kabusha: Hlola njalo ama-o-rings enjoloba ukuze ubone noma yiziphi izimpawu zokuguga noma zokulimala. Ngokuya ngezimo zokusebenza, kungase kudingeke ukuthi uphinde ugcobe ama-o-rings ngezikhathi ezithile ukuze kugcinwe ubuqotho nokusebenza kwawo.

Sengiphetha, ukukhetha amafutha alungile kuma-o-rings enjoloba kubalulekile ukuze kuqinisekiswe ukuqina kwawo nokusebenza kahle. Amafutha e-Silicone, amafutha asekelwe ku-petroleum, namafutha e-fluorinated avame ukusetshenziswa, ngalinye linikeza izinzuzo eziyingqayizivele ngokusekelwe ezidingweni zohlelo lokusebenza. Ukucabangela ukuhambisana phakathi kwamafutha nenjoloba kubalulekile ukuvimbela noma yikuphi ukusabela okungekuhle. Ngokulandela amasu okusebenza afanele kanye nokwenza ukuhlola okuvamile, ungakwazi ukwandisa ukusebenza nempilo ye-o-ring yerabha, uqinisekise ukuvalwa okuthembekile kwezinhlelo zokusebenza ezihlukahlukene zezimboni nezasekhaya.
