Khetha intambo yensimbi engagqwali efanele isicelo sakho

Ukuze intambo yensimbi engagqwali isetshenziswe ngendlela engabizi futhi ephephile, intambo yensimbi engagqwali kumele ikhethwe kahle kulezi zici ezilandelayo. Ukukhetha intambo yensimbi engagqwali kufanele kucatshangelwe ngokwezinhlelo zokusebenza ezahlukene.

Intambo yocingo iphula ukudonsa. Esimweni sobubanzi obuthile bentambo yocingo kanye namandla okudonsa, intambo yocingo ene-coefficient yobuningi bensimbi (okungukuthi, isilinganiso sendawo ye-cross-sectional yentambo nendawo yomthwalo wentambo) kufanele kukhethwe. Ngokuvamile, ukulandelana kwe-coefficient yobuningi bentambo yocingo ukuthi intambo yokuxhumana ebusweni inkulu kunentambo yokuxhumana yentambo, kanti intambo yokuxhumana yentambo inkulu kunentambo yokuxhumana ekhombayo.
Ukumelana nokukhathala. Ngaphansi kwezimo ezivamile, intambo yokuxhumana ebusweni ingcono kunentambo yokuxhumana yomugqa, kanti intambo yokuxhumana yomugqa ingcono kunentambo yokuxhumana ekhomba; intambo eqinisiwe ingcono kunentambo engaqinisiwe; isakhiwo esifanayo singcono ohlangothini olufanayo kunokuqina okuphambeneyo; isilinganiso sentambo yokuxhumana yomugqa wefayibha singcono; intambo yokuxhumana yomugqa wensimbi ilungile.
Ukumelana nokuguguleka. Uma indawo yokuxhumana phakathi kwe-intambo yocingo yensimbifuthi i-pulley noma i-reel, uma ukucindezeleka kokuthinta kuncane, kulapho ukumelana kokuguguleka kuba ngcono khona. Ngakho-ke, i-oda lokumelana nokuguguleka yintambo yokuvala, intambo yentambo enomumo okhethekile, intambo enezintambo eziningi, kanye nentambo yentambo eyindilinga. . Ngokumelana nokuguguleka kwangaphandle, ububanzi bentambo yangaphandle bungcono kakhulu; ngokumelana nokuguguleka kwangaphakathi, ukuxhumana ngentambo kanye nokuxhumana kwendawo kuphakeme kunokuxhumana okuqondile.
Ukumelana nengcindezi. Ikakhulukazi ikhono lentambo yensimbi yokumelana nokuguquguquka kwesakhiwo lapho icindezelwa eceleni. Ingqikithi yentambo yensimbi evamile ingcono kunengqikithi yentambo yefayibha, kanti intambo yesitoko incane kunentambo yesitoko. Ukuxhumana komugqa kungcono kunokuxhumana kwephuzu, ukuxhumana kwendawo kungcono kunokuxhumana komugqa, futhi isakhiwo esifanayo singcono kunesiqondiso esifanayo.
Ukuthamba. Uma inani lezintambo zensimbi lilikhulu ngobukhulu bentambo efanayo, kulapho i-flexibility iba nkulu khona (isilinganiso sobubanzi bentambo yentambo nobukhulu bentambo obukhulu kakhulu entanjeni) futhi kuba ngcono ukuguquguquka.
Ukumelana nokugqwala. Izintambo eziningi zensimbi zisetshenziswa ezindaweni ezinomoya kanye nasezindaweni ezigqwala ezinobuthi noma ezine-alkaline. Umkhuba ubonisile ukuthi ukukhetha i-galvanized, i-zinc aluminium alloy, i-oil seal-resistant rust-proof, ukunciphisa umswakama womongo, i-nylon yokumboza, ipulasitiki kanye nezinye izindlela zokulwa nokugqwala kuzothuthukiswa kakhulu. Impilo yenkonzo yentambo yensimbi.
Ukunwebeka kwesakhiwo kanye ne-elastic modulus. Uma ukusetshenziswa noma ukulungiswa kwentambo ubude obungaguquki kuyinkinga noma kunzima, intambo yentambo enobude obuncane besakhiwo kanye ne-elastic modulus enkulu kufanele ikhethwe. Ngaphansi kwezimo ezijwayelekile, ukunwebeka kwesakhiwo sentambo yensimbi cishe kungama-0.1%-0.2%, kanti okwentambo yentambo yentambo ye-fiber core kungu-0.5%-0.6%. Ukunwebeka kwesakhiwo sentambo yensimbi ecutshungulwa ngokuzilungisa kungancishiswa ngo-0.1%-0.3%, futhi ngesikhathi esifanayo kungathuthukiswa. I-Elastic Modulus.
