Ama-Gasket Enjoloba

Kuphi Ongakusebenzisa: Umhlahlandlela Wokusebenzisa Ama-Gasket Enjoloba, Izimbozo Zothuli, Izimbozo ze-V, kanye nama-O-rings

Onjiniyela babhekene nenselele eqhubekayo: ukukhetha uphawu olufanele lomsebenzi. Nsuku zonke, ubheka amapulani, uvula izincwadi zokulungisa, noma uhamba phansi kokukhiqiza. I-flange iyavuza. Isilinda iyaphela. Umgodi uyaphela. Uyini imbangela? Ngokuvamile ukukhetha uphawu olubi. Lo mhlahlandlela unikeza izimo ezisebenzayo zokukusiza ukhethe phakathi kwama-gasket enjoloba, ama-dust seal, ama-V seal, kanye nama-O rings. Ama-Rubber Gasket afaneleka kakhulu kuma-flange joints angaguquki.

Cabanga ngendlu yokufutha. Izindawo ezimbili zensimbi eziboshwe ndawonye. Zibukeka ziyisicaba, kodwa ngaphansi kwe-microscope, zigcwele imihuzuko, izimpawu zamathuluzi, nezigodi ezincane. Uketshezi luthola lezo zindlela. I-gasket yerabha ihamba phakathi kwazo. Uqinisa amabhawodi. I-gasket iyacindezela, igeleze kulezo ziphambeko, ivimbe ukuvuza. Zisebenzise ezindlini zokufutha, ezimbozweni zamavalvu, ezindlini zokufutha amapayipi, kumaphaneli okufinyelela. Izindawo ezinkulu? Izimo ezingajwayelekile? Ayikho inkinga. Uma ukusetshenziswa kwakho kuhilela izindawo ezimbili ezimile ezidinga ukuvalwa, i-gasket yerabha ivame ukuba yisisombululo. Khumbula: azizona zezingxenye ezihambayo.

Manje cabanga ngesilinda se-hydraulic esise-backhoe. Induku iyanwebeka futhi ihoxe, ingena futhi iphume kwisilinda. Uthuli, udaka, isihlabathi kugcwele yonke indawo. Uma lezo zinto ezingcolisayo zidlula uphawu lwenduku, zishaya udonga lwesilinda, zibhubhise i-piston, zonakalise yonke iyunithi. Yini oyengezayo? Izisilinda Zesilinda ze-hydraulic, ama-actuator e-pneumatic, ama-linear guides, nanoma yimuphi umgodi ophindiselayo ovezwe othulini.

Zifake ohlangothini lwangaphandle lwesivalo sokucindezela esiyinhloko. Umsebenzi wazo ukukhipha, hhayi ukugcina. Udebe oluguquguqukayo lusula induku njalo uma ihoxa. Lususa udaka, ukungcola, amaconsi amanzi. Uma imishini yakho isebenza ezindaweni ezinothuli, ezinodaka, noma ezimanzi, isivalo sothuli sizokwandisa isikhathi senkonzo kakhulu. Ziyisivikelo sokuqala ekungcoleni. Zishintshe njalo; ziguga ngokushesha kunezivikelo zokucindezela.

Kodwa kuthiwani ngamashafti ajikelezayo? Ama-motor kagesi. Ama-gearbox. Ama-conveyor rollers. Lawa mashafti ajikeleza ngokushesha, avame ukungahleleki kahle, ngezinye izikhathi anezindawo ezimagebhugebhu ngenxa yokuguga. I-lip seal ejwayelekile izoshisa kakhulu, iklabalase, futhi yehluleke ngokushesha. Lapha, i-geometry ehlukile isebenza kahle kakhulu. Ama-V seal ayinketho yamashafti ajikelezayo anezindawo ezimagebhugebhu, ezigijimayo, noma ezimagebhugebhu.

Ingxenye yesiphambano esimise okwe-V ihlakaniphile. Njengoba ishaft ijikeleza, amandla e-centrifugal aphonsa umlomo wesivalo ngaphandle. Ayithinti kakhulu i-counterface, ngakho-ke ukungqubuzana kuncane. Isimo sidala isenzo sokupompa esisunduza ukungcola kude nesivalo. Akukho ukulingana okudingekile. Uyifaka kushaft; iziqondisa yona. Zisebenzise kuma-motor kagesi, kuma-gearbox input/output shafts, imishini yezolimo, kuma-conveyor rollers. Ziphatha isivinini seshaft esifinyelela kumamitha angu-20 ngomzuzwana. Zibekezelela ukungalungi kahle kwe-angular okungabhubhisa ezinye izivalo. Ukufakwa kuyashesha; awudingi amathuluzi akhethekile.

Ngakho-ke usebenzisa nini uphawu oluvame kakhulu kunawo wonke? Yonke indawo. Amasongo ayisibonakaliso esizenzakalelayo cishe kuzo zonke izinto.

Amasilinda e-hydraulic, ama-valve omoya, ama-coupling asheshayo okuxhuma, ama-fittings oketshezi, kanye nezinye izinhlelo zokusebenza eziningi ezimile nezishintshayo. Umgomo ulula: ukuguqulwa okulawulwayo. Usika umsele, ufake indandatho ye-O, uyicindezele ngengxenye yokuhlangana. Ingxenye eyindilinga yesiphambano iyasicaba, idala ukuxhumana okubili kokuvala. Ukucindezela kwangaphakathi kusunduza indandatho ye-O ohlangothini lokucindezela okuphansi, kwandisa ukucindezela kokuthinta. Kuzinika amandla. Kusebenza kusukela ku-vacuum kuya kukucindezela okuphezulu. Kusebenza kusukela ku--50°C kuya ku-200°C ngezinto ezifanele. Uma une-groove, indandatho ye-O cishe izofanelana.
