Ungakhetha kanjani i-Underwater Bearing?

Kunombono oyiphutha ovamile wokuthi wonke ama-bearings amelana nokugqwala afanele ukusetshenziswa ngaphansi kwamanzi, kodwa akunjalo. Amarobhothi angaphansi kwamanzi, ama-drones, ama-propeller shafts nama-conveyor angaphansi kwamanzi konke kudinga ukucatshangelwa komklamo othile kanye nama-bearings akhethekile. Yiziphi izinto zokuthwala ezifanele ukusetshenziswa kwamanzi.

Amanye ama-bearings amelana nokugqwala angasebenza lapho echayeke emanzini ahlanzekile, amanzi anosawoti, isitimu noma amanye amakhemikhali, kodwa akuwona wonke alungele ukusetshenziswa okuqhubekayo ngaphansi kwamanzi. Ukucwilisa ngokuphelele i-bearing kungaba nomthelela omubi wokuphila kwayo, kuye ngento eyenziwe ngayo. Isibonelo, ama-bearings ensimbi engagqwali angama-440. Ziyakwazi ukumelana kakhulu namanzi ahlanzekile namakhemikhali abuthakathaka, kodwa uma zifakwe emanzini anosawoti noma zicwiliswe ngokuphelele, zizogqwala ngokushesha.

Amabhereli avamise ukuhluleka ngaphambi kwesikhathi ngenxa yokugqwala, ukungasebenzi kwe-lubricant noma ukungcoliswa. Uma i-bearing ingafanele ukusetshenziswa isikhathi eside ngaphansi kwamanzi, amanzi angangena engxenyeni futhi enze ihaba ngalezi zinkinga ezivamile. Uma uphawu lwezindlu luphuka, uketshezi lungangena ohlelweni futhi lunciphise ukuthambisa, kudala ukungqubuzana okwengeziwe okungalimaza ingxenye ebanzi. Amanzi anosawoti noma amakhemikhali nawo angagqwala, okuholela ekunqanyulweni kwesikhathi sokuphila kwengxenye. Ngakho-ke khetha i-bearing ye-underwater kufanele ngakho-ke ucabangele ukusetshenziswa kanye nemvelo ye-bearing ukuze uqiniseke ukuthi okokusebenza kwabo akuboli ngokungalindelekile futhi kuholele ekunciphiseni isikhathi esibizayo.

 

Ukukhetha i-bearing efanele

Kunezinhlobo eziningi zama-bearings afanele ukucwiliswa emanzini, kodwa ukukhetha ama-bearings afanele wohlelo kuyisihluthulelo.

Ama-Ceramic bearingsazithintwa amanzi anosawoti, ngakho-ke ayasebenza ekusetshenzisweni kwedrone ngaphansi kwamanzi ezindaweni zamandla asogwini. I-Zirconium dioxide noma izinto ze-silicon nitride ziqinile kakhulu futhi zingamelana nemithwalo ephezulu engadingeka kuma-propellor noma kuma-conveyors angaphansi kwamanzi.

Amabhodi epulasitikinazo zimelana nokugqwala okukhulu emanzini ahlanzekile nanosawoti futhi zingasebenza kahle uma zicwiliswe ngokuphelele. Ezinye izindlela zepulasitiki ziyisixazululo esingabizi kakhulu futhi zinezinga eliphansi lokungqubuzana, nakuba umthamo womthwalo uphansi kunensimbi noma ama-ceramic bearings.

316ama-bearings ensimbi engagqwalizisebenza kahle zicwiliswe emanzini ahlanzekile ngaphandle kokugqwala nangaphansi kwamazinga okushisa aphezulu, ngakho-ke ingasetshenziswa ekulayisheni okuphansi nezinhlelo zesivinini embonini yasolwandle, njenge-propellor shaft. I-bearing izophinde imelane nokucwiliswa emanzini anosawoti uma kukhona ukugeleza kwamanzi njalo phezu kwe-bearing ukuze kunikeze umoya-mpilo odingekayo ukusiza ukuvimbela ukugqwala.

Ukutshala imali ekugcobiseni okufanele kuzoqinisekisa ukuthi ukusebenza kahle kwe-bearing kuhlala kuphezulu. Amafutha angangeni manzi nawo angengezwa, ngakho ukuthambisa akuhlanjululwa nganoma yikuphi ukuthintana kwamanzi.Akuwona wonke ama-bearings resistant corrosion afaneleka isikhathi eside ngaphansi kwamanzi, ngakho-ke khetha ama-bearings afanelekile, njenge-ceramic, ipulasitiki noma ezinye izinsimbi, kuzoqinisekisa ukuthi imikhiqizo inesikhathi eside sokuphila, ngaphandle kwesidingo sokushintshwa njalo kwama-bearings awonakele noma agqwalile.Khetha izimo ezihlukene i-arekta engakwazi ukumelana nayo kusiza ukuthuthukisa ukusebenza kahle nokunciphisa izindleko eziphelele zezingxenye ezishintshayo.
