Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
Akukho sivinini esisodwa sedrama sokuxuba ikhonkrithi esinikeza umphumela omuhle kakhulu kuwo wonke umshini. Abaxubi bendawo abaphathekayo bangasebenza cishe ngo -20-25 rpm ezibonelweni zomkhiqizi ezishicilelwe, kuyilapho i-ACI ibeka ukuxubana okuvamile kweloli nokuxuba ku- 12-18 rpm . Umehluko ubalulekile ngoba usayizi wesigubhu, i-geometry ye-blade, ivolumu ye-batch kanye nohlobo lokuxuba kushintsha indlela ukhonkrithi oluhamba ngayo ngaphakathi kwesigubhu. Ukujikeleza okusheshayo akusho ukuthi ukhonkrithi olungcono ngokuzenzakalelayo; uma umxube usebenza ebangeni lawo elifanele, ukujikeleza okuphelele kanye nesikhathi sokuxuba kuba yinto ebaluleke ngokufanayo.
Kwabaxubi abaphathekayo, inkomba ethembeke kakhulu ububanzi bokusebenza bomkhiqizi womshini. I-Marshalltown icacisa cishe ama-rpm angu-20-25 kwabaxubi bayo bekhonkrithi abaphathekayo futhi incoma cishe umzuzu owodwa wokuxuba ngebhetshi ngayinye . Lokho akusho ukuthi wonke umxube wekhonkrithi omncane kufanele ulungiswe ube yi-rpm engu-25 ngqo, kodwa kukhombisa ukuthi ijubane lesigubhu nesikhathi sokuxuba kufanele kucatshangelwe ndawonye kunokuphathwa njengezilungiselelo ezihlukile.
Abaxubi bamaloli basebenzisa iphethini ehlukile yokusebenza. I-ACI ithi abaxubi bamaloli bavame ukusebenza cishe nge -12-18 rpm ngesikhathi sokuxuba. Ngohlelo lokulayisha olufanele, cishe ukujikeleza kwama-drum okungu-70-100 ngokuvamile kufanele kuhlinzeke ngokuxuba okwanele. Uma kungezwa ingxube enciphisa amanzi ebanga eliphezulu endaweni, i-ACI incoma ukujikeleza okwengeziwe okungu-30 ukuze kuhlanganiswe kahle.
| Isimo Sokusebenza | Isivinini Esishicilelwe | Ukuvukela / Isikhathi |
|---|---|---|
| Isibonelo sokuxuba esiphathekayo | 20–25 ngomzuzu | Cishe umzuzu owodwa |
| Ukuxuba iloli - ukuxuba okuvamile | 12–18 ngomzuzu | ukuvukela okungu-70–100 |
| Umxube weloli + i-HRWR kungeziwe endaweni | Isivinini sokuxuba | Cishe ama-revolution angu-30 engeziwe |
| Ukuxuba iloli ngemva kokuxuba sekuqediwe | Ngaphansi kwe-6 rpm | Isigaba sokucasuka |
| Ukuxuba iloli ngesikhathi sokuhamba | Cishe 2–4 rpm | Gcina ukhonkolo oxubile |
Isifundo esiwusizo silula: i-RPM yokuxuba ikhonkrithi ephathekayo kanye ne-RPM yokuxuba iloli akuyona imifanekiso eshintshashintshayo .
Cha. Uma umshini wokuxuba ufinyelela ibanga lesivinini owakhelwe lona, ukwenza nje isigubhu sijike ngokushesha akuqinisekisi ukufana okungcono. Imiyalelo ye-Marshalltown yomshini wokuxuba ophathwayo ibeka isigubhu ku-20-25 rpm bese igxila ekuvumeleni cishe umzuzu owodwa ukuthi ibhetshi lixube. Ngamanye amazwi, umshini udinga ukunyakaza okwanele nesikhathi esanele; isivinini sodwa asikwazi ukuthatha indawo yobude bokuxuba.
Isimiso esifanayo sivela esiqondisweni se-ACI truck-mixer. Ngemva kokujikeleza okungaba yi-100 ngesivinini sokuxuba , i-ACI itusa ukunciphisa isigubhu sibe isivinini sokushukuma esingaphansi kuka -6 rpm . Ngesikhathi sokuhamba, cishe u-2–4 rpm uvamile. Ngaleso sikhathi, umsebenzi wesigubhu ushintshile: asisazami ukuhlanganisa izithako ngamandla, kodwa ukuvimbela ukhonkolo oxubile ukuthi ungahlali.
Ngakho-ke umshini wokuxuba awuyona umshini wokuwasha ojikelezayo. Uma inqwaba isixutshwe kahle, isivinini esengeziwe sinikeza umshini ukuzivocavoca okwengeziwe.
Kokubili kubalulekile, kodwa uma isigubhu sesisebenza ku- RPM efanele yokuxuba ikhonkrithi , isenzo sokuxuba sonke siba yisilinganiso esiwusizo kakhulu. I-ACI isebenzisa ukujikeleza okungu-70-100 njengereferensi yokuxuba iloli ngoba inqwaba idinga ukuphakanyiswa okuphindaphindiwe, ukuwa nokugoqwa ukuze ifane. Lokhu kufundisa kakhulu kunokucaphuna i-RPM yodwa ngoba i-15 rpm imizuzwana embalwa kanye ne-15 rpm imizuzu eminingana ngokusobala azivezi isenzo sokuxuba esifanayo.
Kuma-mixer aphathekayo, imiyalelo yomkhiqizi ivame ukuveza umqondo ofanayo nesikhathi sokuxuba kunokuba kube ukujikeleza okuphelele. I-Marshalltown, isibonelo, ihlanganisa isivinini sayo sesigubhu esingu-20-25 rpm kanye nomzuzu owodwa wokuxuba cishe. Ngakho-ke umthetho wobunjiniyela owusizo uthi: sebenzisa i-RPM ecacisiwe kuqala, bese uqinisekisa ukuthi i-batch ithola isikhathi esanele noma ukujikeleza okuphelele kwesigubhu ukuze ifane.
Yebo. Ukuxuba isikhathi eside akuphephile ngokuzenzakalelayo. I-ACI iphawula ukuthi ukuxuba ngokweqile ngemva kokuxuba okwanele kunganciphisa ukwehla. Uma abaqhubi bese befaka amanzi ukuze babuyisele ukwehla kokuqala, amandla ekhonkrithi angase ehle cishe ngo -8–20% ngehora , kuye ngokushisa kwekhonkrithi kanye nesilinganiso sokulahlekelwa ukwehla.
Lesi esinye sezizathu ezenza opharetha bangagcini ibhetshi ligcwele isivinini sokuxuba ngoba nje isigubhu singaqhubeka nokujika. Uma ukhonkolo usuxutshwe ngokwanele, impendulo efanele ivame ukuthuthela esigabeni sokushukuma esidingekayo kunokwandisa ukuxuba ngesivinini esikhulu. Ukwenza isigubhu sisebenze isikhathi esengeziwe akukwenzi ukhonkolo ukhushulwe.
Izinto ezingaphakathi kwesigubhu nazo zishintsha impendulo. Kukhonkrithi eqiniswe ngefayibha ku-transit mixer, i-ACI itusa isivinini esijwayelekile esingu- 10-12 rpm ngenkathi kufakwa imicu. Ngemva kokuba yonke imicu ingene ku-mixer, i-batch kufanele ithole okungenani ukujikeleza okwengeziwe kwesigubhu okungu-40 , okulingana cishe nemizuzu engu-4-5 , ukukhuthaza ukusabalala kwefayibha okufanayo.
Lesi yisikhumbuzo esiwusizo sokuthi "isivinini sedrama sokuxuba ikhonkrithi esingcono kakhulu" sincike kokubili emshinini kanye nezinto zokwakha. Ikhonkrithi elula, ikhonkrithi egobile kakhulu kanye nekhonkrithi eqiniswe ngefayibha ingadinga izinqubo ezahlukene zokuxuba ngisho nalapho kusetshenziswa i-transit mixer efanayo.
Ukujikeleza kwedrama kusebenza kuphela ngoba ama-blade angaphakathi aphakamisa futhi asabalalise ukhonkolo. I-mixer enobubanzi bedrama obuhlukile noma ukuhlelwa kwe-blade kungadala indlela ehlukile yezinto ezibonakalayo ku-RPM efanayo. Yingakho ukukopisha isivinini komunye umshini kuyingozi ngisho noma womabili ama-mixer ebukeka afana ngaphandle.
Usayizi weqembu nawo ubalulekile. Isigubhu esigcwele kakhulu sishiya isikhala esincane sokuba ukhonkolo uphakamise, ugoqeke futhi ugoqeke endaweni yokuxuba. Uma umshini wokuxuba ngokuzumayo ukhiqiza amaqoqo axubene kabi yize i-RPM ilungile, hlola umthwalo wangempela ngaphambi kokushintsha i-pulley, isivinini senjini noma uhlelo lokushayela. Isivinini esifanelekile sesigubhu asikwazi ukusindisa iqembu elidlula umthamo ohlosiwe womshini wokuxuba.
Uma isigubhu sasisebenza ngokujwayelekile futhi manje sijikeleza kancane kakhulu, inkinga kungenzeka ukuthi ihlobene nomshini kunekhonkrithi. Qala ngokubheka ukuthi isigubhu sihamba kancane yini uma singenalutho noma ngemva kokulayisha kuphela. Isigubhu esingenalutho esihamba kancane sikhomba emthonjeni wamandla, ibhande, i-pulley, i-bearing noma uhlelo lokushayela. Isigubhu esihamba ngokujwayelekile singenalutho kodwa sehla kakhulu ngaphansi komthwalo singase sibonise usayizi we-batch owedlulele noma ukumelana okungavamile komshini.
Kuma-mixer aphathekayo, qhathanisa isivinini sangempela sesigubhu nobubanzi obulinganisiwe bomkhiqizi. Uma umshini okulindeleke ukuthi usebenze cishe ngo-20-25 rpm ungaphansi kwaleso sibalo, hlola uhlelo lokushayela kunokuvumela nje i-batch ukuthi ixube isikhathi eside futhi unethemba lokuthi kuzolunga.

Kungafaneleka kwezinye izixubi eziphathwayo. I-Marshalltown icacisa cishe ama-rpm angu-20–25 emishinini yayo ephathekayo, kodwa eminye imiklamo yezixubi ingadinga ububanzi obuhlukile. Sebenzisa isilinganiso somkhiqizi somshini oqondile.
Hhayi ngokuzenzakalelayo. Amandla ekhonkrithi ancike ezingxenyeni ezixubile, okuqukethwe kwamanzi, ukufana kanye nokuqina, hhayi nje isivinini sesigubhu. I-ACI iphinde ixwayise ngokuthi ukuxuba isikhathi eside okulandelwa amanzi engeziwe ukubuyisela ukuwohloka kunganciphisa amandla cishe ngo-8-20% ngehora.
I-ACI incoma ukucabanga ngokujikeleza kunesikhathi esisodwa esinqunyiwe: cishe ukujikeleza okungu-70–100 ngesivinini sokuxuba somkhiqizi ngokuvamile kwanele ngokulandelana kokulayisha okufanele.
Zisebenza ndawonye. I-RPM ilawula ukuthi isigubhu siphenduka ngokushesha kangakanani, kuyilapho ukujikeleza okuphelele kuchaza ukuthi inqwaba ithola isenzo esingakanani sokuxuba. Ukuxuba okuhle kuvela ngesivinini esifanele, ukujikeleza okwanele kanye nosayizi weqoqo ongaphathwa yi-mixer—hhayi ngokujaha inombolo ye-RPM enkulu kunazo zonke.
Amathegi: isivinini sesigubhu sokuxuba ikhonkrithi, i-RPM yokuxuba ikhonkrithi, isivinini sokuxuba ikhonkrithi, i-RPM yokuxuba i-samente, isikhathi sokuxuba ikhonkrithi, i-RPM yokuxuba ikhonkrithi ephathekayo, ukujikeleza kwesigubhu sokuxuba ikhonkrithi, isivinini sokujikeleza kokuxuba ikhonkrithi, ukuxazulula inkinga yokuxuba ikhonkrithi, umthamo wokuxuba ikhonkrithi
