Kunoma yimuphi umakhenikha ochwepheshe noma indawo yokusebenzela yezimboni, ukuqonda imininingwane yezobuchwepheshe yomshini wokulinganisa okunamandla akuyona nje indaba yelukuluku—kuyisidingo esibalulekile sokufeza ukunemba ekugcinweni nasekukhiqizeni imishini ejikelezayo. Inqubo yokulinganisa i-rotor ithinta ngqo impilo yokusebenza, amazinga omsindo, nokuphepha kwemishini kusukela kuma-crankshaft ezimoto kuya kuma-rotor turbine ezimboni. Nokho, abathengi abaningi bazithola bedidekile ngohlu lwamapharamitha ezobuchwepheshe afakwe kumadatha omkhiqizo, bavame ukudida ukunemba nesivinini noma umthamo womthwalo nekhwalithi yokulinganisa. Lo mhlahlandlela obanzi uklanyelwe ukuchaza amapharamitha ayisisekelo emishini yokulinganisa okunamandla, uhlinzeka abakhenikha nabathengi ngolwazi oludingekayo ukuze benze izinqumo zokuthenga ezinekhono. Ekupheleni kwalesi sihloko, uzoba nokuqonda okucacile ukuthi yini okushiwo yileyo naleyo imininingwane, ukuthi ithinta kanjani uhlelo lwakho, nokuthi ungahlanganisa kanjani lezi zilinganiso ukuze uthole ukusebenza okuhle kakhulu emsebenzini wakho othize. Noma ngabe umusha emkhakheni wemishini yokulinganisa noma ufuna ukuthuthukisa isistimu yakho ekhona, lo mhlahlandlela uyisiqondiso sakho esibalulekile sokukhetha umshini ofanele.

Ukunemba kokulinganisa cishe kuyipharamitha ebaluleke kakhulu lapho uhlola noma iyiphi umatshini wokulinganisa obalulekile, njengoba uchaza inani elincane kakhulu lokungalingani uhlelo olungakuthola futhi lulungise ngokuthembekile. Lesi sicaciso sivame ukuvezwa ngamayunithi amagremu (g) noma amamiligremu (mg), emelela ukungalingani okuncane okusele umatshini ongakulinganisa ngemuva komjikelezo ophelele wokulinganisa. Ngokwesibonelo, umatshini wokulinganisa onokunemba okuphezulu ungase unikeze ukunemba okungu-0.01 mg kwama-rotor amancane asetshenziswa kuma-gyroscopes ezindiza, kanti umatshini wokulinganisa ojwayelekile wezimoto ungase usebenze ebangeni lika-0.1 kuye ku-1.0 g wezingxenye ezijwayelekile zokudonsa. Umthetho oyisithupha ulula: uma isidingo sakho sokudlidliza siqine kakhulu, ukunemba okuphezulu kokulinganisa kuyadingeka. Kodwa-ke, ukujaha ukunemba okuphezulu ngaphandle kokucabangela ukonga izindleko kungaholela ekuchithweni okungadingekile, njengoba omatshini abaqine kakhulu bebiza kakhulu futhi bangadinga izimo zemvelo eziqine kakhulu njengamagumbi alawulwa izinga lokushisa. Ikhwalithi yezinzwa—ezivame ukuba ama-transducer e-piezoelectric noma e-eddy-current—idlala indima enkulu ekunqumeni ukunemba okungafinyelelwa, njengoba izinzwa ezisezingeni eliphezulu zithwebula izimpawu zokudlidliza ezicashile ngokunemba okukhulu. Kubaqeqeshi abasebenza ezintweni ezijwayelekile zezimboni, umatshini onokunemba phakathi kuka-0.1 g no-0.5 g uvame ukunikeza imiphumela emihle, kanti izicelo ezikhethekile njengezinduku ezisheshayo zidinga ukunemba okungaphansi kwamamiligremu. Ukuqonda ubudlelwano phakathi kokunemba kokulinganisa ukungalingani namazinga okudlidliza avumelekile esikhundleni sakho esithile kuyisisekelo sokukhetha okuhlakaniphile emakethe yezinto zokulinganisa.

Ibangela lokulinganisa okunamandla lomshini wokulinganisa libeka isivinini sokujikeleza lapho ungakwazi khona ukukala nokulungisa ukungalingani kahle, okuvame ukuchazwa ngamajikajika ngomzuzu (r/min). Izinhlobo ezahlukene zemishini ejikelezayo zisebenza ngesivinini esihlukahlukene kakhulu: ipropela yomkhumbi ejikeleza kancane ingasebenza ku-100 r/min kuphela, kanti i-turbine yedrili yamazinyo ingequla u-300,000 r/min. Umshini wokulinganisa ovumelana nezimo wezobuchwepheshe obujwayelekile kufanele uhlanganise ububanzi obubanzi, isibonelo esivamile singaba ububanzi obungu-500 kuye ku-5,000 r/min, okubandakanya izinto eziningi zezimoto ezifana namadiski ebhuleki, ama-pulley, nemihlangano ye-clutch. Ukukhethwa kwebanga lesivinini elifanele kubalulekile ngoba ubukhulu bezingcindezi zokungalingani bukhula kakhulu ngesivinini sokujikeleza, okusho ukuthi i-rotor ebonakala ilinganiswe ngesivinini esiphansi ingadala ukudlidliza okubhubhisayo ngesivinini esiphakeme. Imishini yesimanje yokulinganisa ivumela abasebenzisi ukuthi bakhethe izivinini zokuhlola ezithile ezihambisana nesivinini sokusebenza esilinganiselwe somsebenzi, baqinisekise ukuthi ukulungiswa okwenziwayo kuhambisana nezimo zangempela. Kubachwepheshe abalungisa izinhlobonhlobo zemishini, ukutshala imali kumshini wokulinganisa onamandla onebanga lesivinini elilungisekayo noma elibanzi kunikeza ukuguquguquka okukhulu, okuvumela ukulinganisa okunembayo kuzo zonke izinhlobo zemisebenzi ngaphandle kokudinga imishini ehlukene yezivinini eziphakeme neziphansi. Ngaphezu kwalokho, ukuzinza kohlelo lokulawula isivinini kanye nokunemba kwemoto yokudonsa kuthinta ngqo ukungaguquguquki kokulinganisa ukungalingani, kwenza ubunjiniyela obuqinile kule ndawo kube uphawu lwemishini yokulinganisa ethembekile evela kubakhiqizi abahlonishwayo.

Ukucaciswa kwebanga lobunzima be-workpiece kuchaza isisindo esincane nesiphezulu umshini wokulinganisa obunyakazayo ongawuthwala, okuchaza ngqo usayizi nohlobo lwezingxenye ongazicubungula. Lo mpharamitha uvame ukubhalwa ngamakhilogremu (kg) futhi umele umthamo womshini wokuthwala wamabheringi okweseka kanye nesistimu yokushayela. Ngokwesibonelo, umshini wokulinganisa ophumelelayo owenzelwe izicelo zendawo yokusebenzela encane ungaba nebanga lobunzima lika-0.1 kg kuye ku-10 kg, ofanele ngokuphelele ama-armature, ama-spindle, kanye nama-fan amancane, kanti imishini yokulinganisa yezimboni esindayo ingabhekana nama-workpiece angaphezu kwamathani amaningana. Ukukhetha umshini ongebanga lobunzima elingafanele kuyisiphutha esivamile nesibizayo: umshini ongaphansi ungakwazi ukuthwala izingxenye ezisindayo ngaphandle kokulimaza amabheringi noma ukubeka engcupheni ukuphepha, kanti umshini omkhulu ungase uswele ubucayi obudingekayo ukukala ama-rotor alula ngokunembayo. Abasebenzi bemishini kufanele bahlaziye ngokucophelela lonke uhla lwama-workpiece abawasebenzisayo njengamanje, kanye nemisebenzi yesikhathi esizayo, futhi bakhethe imishini yokulinganisa enesilinganiso sokuphepha esingaba ngu-20% ngaphezu kwengxenye esindayo elindelekile. Umklamo wokusekelwa kwe-workpiece—njengama-roller, ama-V-block, noma ama-self-centering chucks—nawo uthinta indlela izinhlobo ezahlukene zobunzima ezibhekwa ngayo, nezinye izinhlelo ezisezingeni eliphezulu zinikeza izisekeli ezilungisekayo noma ezishintshwayo ukuze zivumelane nezimo ezahlukene. Kubasebenzi bemishini yezimoto kanye nezimboni ezijwayelekile, umshini wokulinganisa obunyakazayo ongebanga lobunzima elisuka ku-0.5 kg kuye ku-50 kg uhlanganisa iningi lemisebenzi ejwayelekile yokulungisa kanye nokukhiqiza kabusha, kusuka kumawili we-turbocharger kuye kuma-rotor amancane aphakathi ezinjini zikagesi. Ukuqonda lo mpharamitha kuqinisekisa ukuthi utshalomali lwakho kubuchwepheshe bokulinganisa obunembayo buvumelana nezimo zangempela zemisebenzi yakho yansuku zonke.

Isilinganiso sokunciphisa ukungalingani (URR) siyisikhombisi esinamandla kodwa esivame ukunganakwa sokusebenza komshini wokulinganisa okunamandla, esikhombisa njengamaphesenti alinganisa ukuthi umshini ungakwazi ukususa kangakanani ukungalingani kokuqala kumjikelezo owodwa wokulinganisa. I-URR engu-95% isho ukuthi uma i-rotor iqala ngokungalingani okungu-100 g·mm, umshini ungakunciphisa kube yi-5 g·mm kuphela ngemuva komjikelezo owodwa wokulungisa, kushiya kuphela u-5% wokungalingani kwasekuqaleni kusele. Amanani aphezulu e-URR, njengango-98% noma u-99%, akhombisa ikhono elingcono lokulungisa futhi abaluleke kakhulu ezinhlelweni eziphakeme kakhulu lapho ukudlidliza okusele kufanele kuncishiswe ukuze kunwetshwe impilo yama-bearing futhi kuncishiswe umsindo. Izinto ezithinta i-URR engatholakala zihlanganisa ukunemba kwesistimu yokulinganisa, ukulungiswa kwendlela yokulungisa (njengokungeza noma ukususa izinto), kanye nokuqina kwesakhiwo somshini. Umshini wokulinganisa okunamandla onama-URR aphezulu awukhiqizi nje kuphela izingxenye ezisezingeni eliphezulu kodwa futhi unciphisa inani lezinyathelo zokulinganisa ezidingekayo, kuthuthukisa ngokuqondile ukukhiqiza futhi kunciphisa izindleko zokusebenza. Kubachwepheshe bezobuchwepheshe, ukukhetha imishini yokulinganisa ene-URR engaphezu kuka-95% kuvame ukunconywa, njengoba lokhu kunikeza isiqinisekiso esiqinile sokuthi ngisho nama-rotor anzima angalethwa ngaphakathi kwamaleveli okubekezelelana ngokusebenza kahle. Kubalulekile ukuqaphela ukuthi i-URR ihlangana nepharamitha yokunemba kokulinganisa: umshini onokunemba okuhle kodwa onama-URR aphansi uzodinga izinyathelo eziningi zokulungisa, kanti i-URR ephezulu ihlanganiswe nokunemba okwanele iletha imiphumela efanele. Lapho kuqhathaniswa izinhlobo ezahlukene zemishini yokulinganisa, i-URR inikeza isilinganiso esiqondile, esijwayelekile sokuhlola ukusebenza okuphelele kanye nokusebenza kahle kwenqubo yokulinganisa nokulungisa ukungalingani.

Ukuhlanganisa imingcele emine eyisisekelo—ukucaca kokulinganisa, ububanzi besivinini, ububanzi bobunzima bomsebenzi, kanye nesilinganiso sokunciphisa ukungalingani—kuhlelo oluhlangene lokukhetha kudinga ukuhlola okuhlelekile kwezidingo zakho ezithile zohlelo lokusebenza. Qala ngokufaka uhlu lwezinhlobo zama-rotor owalinganisayo njalo, uqaphele izivinini zawo zokusebenza, ubunzima, namazinga okulinganisa adingekayo ngokuya ngamazinga omhlaba wonke njenge-ISO 1940. Ngokwesibonelo, isitolo esisebenza ngokukhethekile ekwakheni kabusha ama-turbocharger ezimoto kufanele siphambanise umshini wokulinganisa obunamandla ngokucaca okuphezulu (0.01–0.1 g) kanye nobubanzi besivinini obukwazi ukudlula i-100,000 r/min, kanti indawo elinganisa abalandeli bezimboni ingagxila kububanzi obubanzi bobunzima kanye nokwakhiwa okuqinile. Ukusebenzisana phakathi kwale miqulu kusho ukuthi akukho ukucaciswa okukodwa okutshela yonke indaba; umshini olinganiswe kahle uhlinzeka ngokuhlanganiswa okuhambisanayo okufaneleka indlela yakho yokusebenza eyinhloko. Lapho uhlola ukuthengwa okungenzeka, cabanga hhayi kuphela ngokucaciswa okuyinhloko kodwa futhi nekhwalithi yokwakhiwa, idumela lomkhiqizo, kanye nokutholakala kusekelo lwangemuva kokuthengisa. Ngalesi sikhathi, kufanele kuqokonyiswe ukuthi i-Shenkai, njengengxenye yomndeni wakwaYunnan Mechanic Auto Technology Co., ifanekisela izindinganiso zobunjiniyela bokucacisa abazidingayo abakhanda izimoto. Ngokuzibophezela okuqinile ekukhiqizeni imishini yokulinganisa enokusebenza okuphezulu ebonakala ngokucaca okungajwayelekile, ububanzi besivinini obubanzi, nokwakhiwa okuhlala njalo, i-Shenkai ihlinzeka ngezixazululo ezimelana nezidingo zamaworkshop anamanje. Ifilosofi yenkampani, egxile ekukhandeni okucacile nasekubuseni kobuchwepheshe, iqinisekisa ukuthi umshini ngamunye uhlinzeka ngesevisi ethembekile nemiphumela engaguquki kuzo zonke izinhlobo zezicelo. Ngaphezu kwalokho, ukuvakashela ikhasi lomkhiqizo kukuvumela ukuthi uhlole lonke uhla amamodeli atholakalayo, kanti ikhasi elithi Mayelana Nathi lichaza izigaba zomkhiqizo kanye nokuzibophezela kwesevisi. Kulabo abanezidingo ezihlukile, isevisi eyenziwe ngokwezifiso ihlinzeka ngezixazululo eziqondene nawe ukuze zihambisane nobujamo obuthile bomsebenzi kanye nevolumu yokukhiqiza. Ngokuhlanganisa ukuhlaziywa okucophelelayo kwemingcele nokukhethwa komkhiqizi omethembayo njenge-Shenkai, abakhanda izimoto bangatshala emishini yokulinganisa ethuthukisa kokubili ukuzinza kokusebenza nokusebenza kokukhiqiza.

Ukuqonda amapharamitha abalulekile womshini wokulinganisa okunamandla akuyona nje into yokufunda—kuyisidingo esisebenzayo kunoma yimuphi umakhenikha noma umphathi we-workshop ohlose ukufeza ukusebenza komshini okuzinzile, ukunciphisa isikhathi sokungasebenzi, nokwelula impilo yesevisi yezingxenye ezijikelezayo. Ukunemba kokulinganisa, ububanzi besivinini, ububanzi besisindo somsebenzi, kanye nesilinganiso sokunciphisa ukungalingani kwakha izinsika ezine zokukhetha okuhlakaniphile, ngayinye ithonya ezinye ebuhlotsheni obuyinkimbinkimbi kodwa obulawulekayo. Ngokuhlaziya ngokuhlelekile izidingo zakho zohlelo bese uzifanisa nalezi zici, ungagwema izinkinga ezibizayo zokucacisa ngokweqile noma ukucacisa kancane izinto zakho zokulinganisa. Imvelo ephilayo yobuchwepheshe besimanje bokulinganisa inemishini ekwazi ukubhekana nakho konke kusuka kuma-rotor amancane anembayo kuya kuma-spindle amakhulu ezimboni, inqobo nje uma wazi ukuthi ubheka ini. Khumbula ukuthi umshini wokulinganisa okunamandla ongcono kakhulu we-workshop yakho yilowo ohambisana nomsebenzi wakho wamanje ngenkathi unikeza ukuguquguquka ukuze ubhekane nokukhula kwesikhathi esizayo. Lapho ukhetha isixazululo esisekelwa ubunjiniyela obuqinile nokuzibophezela okucacile kwekhwalithi—njengokunikezwa yi-Shenkai ne-Yunnan Mechanic Auto Technology Co.—uyatshala hhayi kuphela entweni eyodwa, kodwa ekuthembekeni kwesikhathi eside nokuncintisana komsebenzi wakho wonke. Hlala unolwazi, hluza ngokucophelela, futhi uvumele amapharamitha afanele akuhambise kumshini wokulinganisa ophelele wezidingo zakho eziqondile.
