Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
I-blade yedayimane engasikwanga akusho ngaso sonke isikhathi ukuthi izingxenye zayo zedayimane seziqediwe. I-blade ingase ime kahle ngaphezu kwe-core yensimbi, kodwa i-blade ikhiqiza uthuli, ilahlekelwe isivinini sokusika futhi ihluleka ukungena kukhonkolo. Ezimweni eziningi, inkinga iwukugqokwa kwe-blade yedayimane , okwenzeka lapho isibopho sensimbi singagugi ngokushesha ngokwanele ukuze siveze amadayimane amasha.
Ukucwebezela kuyimbangela eyodwa kuphela engaba khona. I -blade yesaha ekhonkrithi engasikwa ingakhomba namandla enjini aphansi, amabhande okushayela axegayo, i-RPM engalungile, ukugeleza kwamanzi okungekuhle noma umonakalo we-blade. Izimpawu zingase zifane ngemuva kwesaha, ngakho-ke indlela ehlakaniphile ukuhlola i-blade, umshini kanye nezimo zokusika ngokulandelana okucacile. Ukusunduza kanzima kuvame ukwengeza ukushisa, hhayi ukuhlakanipha.
| Lokho okubonayo | Imbangela okungenzeka | Ukuhlolwa kokuqala |
|---|---|---|
| Ubuso obubushelelezi noma obucwebezelayo | Ukucwebezela noma isibopho esiqinile kakhulu | Ukucaciswa kwe-blade kanye nesimo esihlanganisiwe |
| Ukuphakama kwengxenye kuyaqhubeka, kodwa ukusika kuyahamba kancane | Amadayimane amasha awavezwa | Ukuthi ukugqoka okuphephile kuyawubuyisela yini ukusika |
| Ijubane lenjini liwela ngaphansi komthwalo | Ukucindezela kokudla ngokweqile, amandla aphansi noma amabhande axegayo | Isimo senjini, ukucindezeleka kwebhande kanye nokucindezela kokusika |
| Ingaphakathi le-blade liphenduka umbala | Ukushisa ngokweqile noma ukupholisa okubuthakathaka | Ukulethwa kwamanzi, umjikelezo wokusika owomile kanye nesilinganiso se-blade |
| Insimbi eyinhloko iguga ngaphansi kwezingxenye | Ukusika ngaphansi kwezinto eziklwebhayo | Uhlobo lwezinto kanye nokuvikelwa okungaphansi kokusika |
| Imifantu, izingxenye ezingekho noma umongo ogobile | Umonakalo we-blade yesakhiwo | Misa isaha bese ushintsha i-blade |
Ingxenye yedayimane iqukethe amadayimane okwenziwa abanjwe ngesibopho sensimbi. Ngesikhathi sokusika okuvamile, amadayimane agaya izinto ngenkathi isibopho esizungezile siphela kancane kancane. Amadayimane abuthakathaka ayakhululwa, futhi kuvela izindawo ezintsha zokusika ebusweni bengxenye.
Ukucwebezela kuqala lapho lokhu kuguguleka okulawulwayo kuyeka ukusebenza kahle. Isibopho sihlala sivaliwe eduze kwamadayimane agugile, okushiya indawo ebushelelezi engenawo umthelela omusha wedayimane. Ngokusho kuka- Isiqondiso sokuxazulula izinkinga ze-blade yedayimane yaseNorton , i-blade eqinile kakhulu kunendwangu ingase yehluleke ukuveza amadayimane amasha. UNorton uncoma ukuthi kuthuthelwe ekubambisaneni okuthambile uma kudingeka ukubopha okuphindaphindiwe.
Lo mehluko ubalulekile ngoba ukubopha kungavula kabusha indawo ecwebezelisiwe, kodwa akukwazi ukulungisa unomphela imininingwane engalungile ye-blade. Uma i-blade ivala futhi ngemva kwesikhathi esifushane sokusika, izinto zokwakha kanye nokubopha kungenzeka ukuthi akufani kahle.
I-aggregate eqinile, engagugi kakhulu ingase ingagugi ngokushesha ngokwanele. I-blade ivame ukuqala kahle, bese inqamuka kancane njengoba ubuso bengxenye bupholishwa. Ukusebenzisa ingcindezi eyengeziwe yokuphakelwa kungenza injini isebenze kanzima, kodwa akusizi ukuthi i-bond ikhiphe amadayimane abuthakathaka.
Uma i-glazing ibuya ngemva kokufaka i-dressing kanye ne-saw isebenza kahle, ukushintsha i-bond ibe mnene kuvame ukuba yimpendulo efanele yobuchwepheshe. Kumaphrojekthi ahilela kokubili ukhonkolo kanye ne-asphalt, qala uqinisekise ukuthi i-blade ihambisana nezinto ezisetshenziswayo kunokuba ucele incazelo eyodwa ukuthi iziphathe njengezinsika ezimbili ezihlukene.
I-blade ekhethwe kahle isengabhekana nobunzima lapho isaha lingagcini isivinini ngaphansi komthwalo. UNorton weluleka abaqhubi ukuthi bahlole amandla akhona ehhashi kanye nesimo se-drive-belt lapho i-blade ingasiki. Amabhande axegayo, injini engasebenzi kahle kanye nesivinini sokudla esinamandla konke kunganciphisa isivinini se-blade emphethweni wokusika.
Lalela injini njengoba i-blade ingena ekusikeni. Ushintsho oluncane lwethoni luvamile, kodwa ukwehla okukhulu kwesivinini kusikisela ukuthi izinga lokuphakelwa liphezulu kakhulu noma ukuthi amandla awafinyeleli kahle i-blade. Ngaphambi kokusola amadayimane, qiniseka ukuthi injini, amabhande kanye nomphini we-blade kwenza ingxenye yawo yomsebenzi.
I-RPM ye-blade kumele ihlolwe kanye nobubanzi be-blade. Isiqondiso sokusika ukhonkolo sika-MK Diamond Kunconywa isivinini sokusebenza serimi esingaba ngu- 9,500–11,500 wamamitha ongaphezulu ngomzuzu kuma-blade amaningi edayimane. Isivinini esiphansi ngokuvamile sisetshenziselwa izinto eziqinile neziminyene, kuyilapho isivinini esiphezulu sifanela izinto ezithambile nezikhahlayo.
Ithebula layo lesivinini elishicilelwe libonisa ukuthi kungani ububanzi bubalulekile. I-blade ejwayelekile engamasentimitha angu-12 inesivinini sokubhekisela esingu-3,000 rpm, i-blade engamasentimitha angu-14 engu-2,500 rpm kanye ne-blade engamasentimitha angu-20 engu-1,800 rpm. Lawa amanani okubhekisela e-MK, hhayi izilungiselelo ezijwayelekile, kodwa abonisa ngokusobala ukuthi i-blade enkulu ayikwazi ukufakwa ngokuphephile ngokuhlola imbobo ye-arbor kuphela.
| Ububanzi be-blade | I-RPM yereferensi ye-MK | I-MK ayidluli i-RPM |
|---|---|---|
| 12 in / 305 mm | 3,000 ngomzuzu | 5,095 ngomzuzu |
| 14 in / 356 mm | 2,500 ngomzuzu | 4,365 ngomzuzu |
| 16 in / 406 mm | 2,200 ngomzuzu | 3,800 ngomzuzu |
| 20 inches / 508 mm | 1,800 ngomzuzu | 3,000 ngomzuzu |
Landela njalo i-RPM ephezulu ephrintiwe ensikeni ekhethiwe kanye nebanga lesivinini elivunyiwe lesaha. Insikeni ingase ilingane kahle kodwa isajikeleza ngesivinini esingalungile, okuyinguqulo yomshini yokugqoka amabhuzu asayizi ofanele ezinyaweni ezingalungile.
Ukuze kunqunywe ngokumanzi, amanzi kumele afinyelele izinhlangothi zombili ze-blade bese ekhipha uthuli oluhlabayo oluphuma e-kerf. I-MK Diamond inikeza ireferensi yomkhiqizi cishe amagaloni angu-4.5–6 US ngomzuzu , alingana namalitha angu-17–23 ngomzuzu . Isidingo sokugcina sincike ekusaheni, i-blade kanye nesenzo sokuhlanza sokusika, ngakho-ke incwadi yemiyalelo yemishini ihlala iyireferensi yokulawula.
Isivikelo se-blade esimanzi asifakazeli ukuthi amanzi anele afinyelela ezingxenyeni. Hlola zombili izikhala ukuze ubone ukuthi azinawo yini ama-nozzle futhi ubheke ukuthi i-slurry ishiya yini i-clutch ngokukhululeka. Ukusatshalaliswa kwamanzi okungekuhle kungandisa ukushisa, kunciphise ukusebenza kahle kokusika futhi kudale ukuguguleka okungalingani emaceleni.
Ngezinsika ezivunyiwe ezomile, I-Norton yeluleka ngokumelene nokunciphisa okuqhubekayo isikhathi eside futhi incoma ukuvumela i-blade ukuthi ijikeleze emoyeni njalo ngemizuzu embalwa. Izinto eziqinile zingadinga ukupholisa kaningi. Akukho mthetho ojwayelekile wemizuzu emithathu noma emihlanu, ngakho-ke landela imiyalelo yomenzi we-blade.
Ukulethwa kwamanzi kuthinta okungaphezu kokushisa kwe-blade. Izinga le-silika lokwakha i-US OSHA , izinga lesenzo se-silica ekristalu ephefumulayo lingu- 25 μg/m³ , kuyilapho umkhawulo wokuvezwa ovunyelwe ungu- 50 μg/m³ . Zombili zibalwa njengezilinganiso zesikhathi samahora ayisishiyagalombili.
Ithebula le-OSHA 1 lidinga ukuthi amasaha ahamba ngemuva asebenzise uhlelo oluhlanganisiwe oluqhubeka nokunikeza amanzi ensikeni. Umsebenzi wangaphandle usebenzisa indlela yokulawula ebhalwe ohlwini awudingi umshini wokuphefumula owengeziwe, kuyilapho umsebenzi wangaphakathi noma ovalekile udinga okungenani ukuvikelwa kokuphefumula kwe-APF 10. Lezi yizidingo zase-US; osonkontileka kwamanye amazwe kufanele balandele imithetho yendawo yephrojekthi.
| Into ye-OSHA | Imfuneko eshicilelwe |
|---|---|
| Izinga lesenzo se-silica | 25 μg/m³ ngaphezu kwe-TWA yamahora angu-8 |
| Umkhawulo wokuvezwa ovunyelwe | 50 μg/m³ ngaphezu kwe-TWA yamahora angu-8 |
| Ukulawula isaha lokuhamba ngemuva | Ukulethwa kwamanzi okuhlanganisiwe okuqhubekayo |
| Ukusetshenziswa ngaphakathi noma okuvalekile | I-APF encane kakhulu engu-10 |
Misa isaha bese uhlola i-blade ngaphambi kokuzama ukuyilungisa. Ukulungisa kufaneleke kuphela uma i-blade iqinile ngokwesakhiwo futhi ubuso be-segment buvaliwe noma bucwebezelisiwe. Ungalungisi i-blade enemifantu, izingxenye ezingekho, umongo ogobile noma ubuthakathaka obubonakalayo ngaphansi kwezingxenye.
Qinisekisa ukuthi i-blade ilinganiswe ngokwezinto zokwakha, i-saw kanye nendlela emanzi noma eyomile.
Hlola umcibisholo ojikelezayo, i-arbor, ama-flange, amabhande kanye nohlelo lwamanzi.
Sebenzisa indwangu yokugqoka evunyelwe ngumkhiqizi noma ibhlogo elithambile elihudulayo.
Yenza izingcezu ezimfushane zokugqoka, bese umisa bese uhlola ubuso bengxenye.
Buyela ezintweni zokusebenza usebenzisa umfutho wokudla ophakathi nendawo.
I-Norton ibala ibhulokhi ethambile yekhonkrithi noma isondo elidala elirhabaxa njengezinto zokubopha ezingaba khona. Uma ukusika kuthuthuka okwesikhashana kodwa ukugcotshwa kwengilazi kubuya, shintsha imininingwane yesibopho esikhundleni sokuguqula ukugqoka kube yinto yokuzilibazisa yansuku zonke.
| Isimo | Ukubukeka okuvamile | Isenzo esinconyiwe |
|---|---|---|
| Ukucwebezelisa | Ubuso bengxenye ebushelelezi kanye nokuphakama okusebenzisekayo okusele | Hlola ukuthi isibopho sihambisana kahle yini futhi ugqoke kahle yini |
| Ukugqoka okuvamile | Izingxenye ziyancipha ngokulinganayo futhi ukusika kuhlala kuzinzile | Qhubeka nokuhlola bese ushintsha endaweni elinganiselwe |
| Ukusika ngaphansi | Insimbi iba mncane ngaphansi kwezingxenye | Misa uma ibuthakathaka; sebenzisa i-blade enesivikelo esingaphansi kokusika |
| Umonakalo wesakhiwo | Imifantu, izingxenye ezingekho noma umongo osontekile | Shintsha ngokushesha |
Ibhulokhi lokugqoka lingaveza amadayimane amasha, kodwa alikwazi ukulungisa umongo wensimbi oqhekekile. Uma insimbi inomonakalo wesakhiwo, ukushintshwa kuyindlela enengqondo kuphela.
Ngaphambi koku-oda i-blade entsha, qopha phansi izinto, isimo sokuhlanganiswa, imininingwane ye-blade, imodeli yesaha, ububanzi be-blade, i-RPM ephezulu, ukujula kokusika kanye nendlela emanzi noma eyomile. Bese uhlola ukuqina kwebhande, isivinini senjini, ama-shaft bearings, isimo se-flange kanye nokulethwa kwamanzi.
Okuzinikele isaha likakhonkolo elihamba ngezinyawo kufanele isetshenziswe nge-blade ehambisana nezinto kanye nomshini. Ukuze uthole ukusika umgwaqo okujulile, qhathanisa nosayizi we-blade ovunyiwe kanye nokujula kokusika komshini okhethiwe, njengokuthi I-ACE QF400 i-saw yomgwaqo ekhonkrithi .
I-blade ecwebezelayo ivame ukuba nobuso obubushelelezi be-segment, ukuphakama kwe-segment okuwusizo okusele kanye nokulahlekelwa okucacile kwesivinini sokusika. Qinisekisa ukuthi umshini ugcina amandla ngaphambi kokubopha i-blade.
I-blade engaguquki ecwebezelayo ingavame ukugqokwa ukuze kuvele amadayimane amasha. I-blade eqhekekile, egobile noma eyonakele kufanele ishintshwe.
Ukugqwala okuphindaphindiwe kuvame ukukhomba isibopho esinzima kakhulu kunento, amandla aphansi esaha noma ukucindezela okukhulu kokudla. Hlola kabusha imininingwane ye-blade nesimo somshini.
I-MK Diamond inikeza inkomba engaba ngu-4.5–6 US gal/min, noma 17–23 L/min. Ukugeleza kokugcina kumele kulandele imiyalelo yomenzi wesaha ne-blade.
Yishintshe lapho ungqimba lwedayimane olusebenzisekayo lufinyelela umkhawulo walo ophawulekayo, ingxenye ingekho, umongo uqhekekile noma ugobile, noma ukusika okungaphansi kwensimbi kubuthakathaka ngaphansi kwezingxenye.
Isiqondiso Sokubuza Ngomkhiqizo Wemvelo:
Yabelana ngezinto, isimo esihlanganisiwe kanye nokucaciswa kwe-blade uma ucela ukwesekwa kokuxazulula izinkinga.
Faka imodeli yesaha, ububanzi bensingo, usayizi we-arbor, i-RPM ephezulu nokuthi ngabe ukusika kumanzi noma komile.
Izithombe zobuso bengxenye, umongo wensimbi kanye nephethini yokuguguleka zingasiza ekuhlukaniseni ukucwebezela nokusika phansi noma umonakalo wesakhiwo.
