Yiziphi izinzuzo zokukhetha i-granite njengombhede wemishini?

Okokuqala, izakhiwo zomzimba eziphakeme

I-Granite iyinto enzima kakhulu, ubulukhuni bayo buphakeme, ngokuvamile phakathi kwamazinga ayisithupha kuya kwayisikhombisa, kanti ezinye izinhlobo zingafinyelela ngisho namazinga angu-7-8, aphakeme kunezinto zokwakha ezijwayelekile njengemabula, izitini, njll. Ngesikhathi esifanayo, ukuminyana kwe-granite kukhulu, ngokuvamile phakathi kuka-2.5 no-3.1 amagremu per cubic centimeter (noma 2.8-cubi imitha), amandla angafinyelela ku-2.8-cubi ephakeme kakhulu, i-compressive 1 imitha / cubi 3. 150-300Mpa, enekhono elihle lokuthwala nokuzamazama komhlaba. Lezi zici zenza i-granite ekusetshenzisweni kombhede wemishini ingamelana nomthwalo omkhulu nokucindezela, akulula ukuguqulwa nokulimala.

Okwesibili, izakhiwo zamakhemikhali ezizinzile

I-Granite ine-asidi enhle kakhulu kanye ne-alkali ukumelana nokugqwala futhi akulula ukugqwala nokuguguleka ngamakhemikhali. Lokhu kusho ukuthi enqubweni yokwenza imishini, noma ngabe ihlangabezana ne-coolant ebolayo noma i-lubricant, umbhede we-granite ungahlala uzinzile, futhi ngeke uthinte ukunemba kwawo nempilo yesevisi ngenxa yokugqwala okufushane.Nakuba i-granite ine-asidi enhle ne-alkali ukumelana nokugqwala, ibuye igcinwe kahle ngemva kokucubungula, ukwelashwa okufika ngesikhathi kwendawo ukugwema uketshezi olubolayo olugcinwe phezulu isikhathi eside ukuze kulimaze ukunemba kwendawo yayo.

Okwesithathu, i-coefficient yokwandisa okushisayo incane

I-coefficient yokwandisa ukushisa kwe-granite incane, engakwazi ukumelana ngokuphumelelayo nethonya lokushintsha kwezinga lokushisa. Enkambweni yomshini, ngenxa yesizukulwane sokusika ukushisa nokushisa kwe-friction, izinga lokushisa lomshini womshini lizoshintsha. Uma i-coefficient yokwanda okushisayo kombhede inkulu, izobangela ukuguqulwa kombhede, ngaleyo ndlela kuthinte ukunemba kwemishini. Umbhede we-granite uhlukile embhedeni we-cast iron, futhi ngeke uthinteke ukushisa, okunganciphisa ngokuphumelelayo lokhu kuguqulwa nokuqinisekisa ukunemba kokucubungula.

Okwesine, ukumelana nokudlidliza okuhle

Ngenxa yevolumu yayo enkulu nokusebenza okuhle kakhulu kokuvimbela ukudlidliza, umbhede wesisekelo se-granite unganciphisa ngempumelelo ukuphazamiseka kokudlidliza kunqubo yokwenza imishini. Lesi sici sibaluleke kakhulu ekusikeni ngesivinini esiphezulu noma ekwenzeni imishini ngokunemba, okungathuthukisa ikhwalithi yomshini futhi kunwebe impilo yesevisi yethuluzi.

5. Ukunemba okuphezulu kokucubungula

I-Granite iyimpahla yemvelo enokuthungwa okufanayo nombala, okungacutshungulwa kube yizimo nobukhulu obuhlukahlukene ngokwezidingo zangempela. Ngokusika, ukuhlela, ukugaya, ukubhoboza, ukuphonsa kanye nolunye uchungechunge lokucubungula, i-granite ingacutshungulwa ibe ngumbhede wemishini onembile futhi osezingeni eliphakeme ukuze uhlangabezane nezidingo zokunemba nokuqina kwemishini yesimanje.

6. Izindleko zokunakekela eziphansi

Umbhede we-granite akulula ukuwugqoka futhi uwohloke ngesikhathi sokusetshenziswa, ngakho-ke izindleko zokuwunakekela ziphansi kakhulu. Ukuhlanza nokuhlola okuvamile kuphela okungayigcina isesimweni esihle sokusebenza.

Kafushane, ukukhethwa kwe-granite njengombhede wemishini kunezinzuzo eziningi, kufaka phakathi izakhiwo eziphakeme zomzimba, izakhiwo zamakhemikhali ezizinzile, i-coefficient encane yokwandisa ukushisa okushisayo, ukumelana nokudlidliza okuhle, ukunemba okuphezulu kokucubungula kanye nezindleko eziphansi zokulondoloza. Lezi zinzuzo zenza umbhede we-granite emkhakheni wokukhiqiza imishini unezinhlobonhlobo zamathemba ohlelo lokusebenza.
