Ungawuthenga kanjani umshini womjovo we-china ofanelekile

Sengisho nje, iningi lamakhasimende asebenze embonini yokubumba umjovo iminyaka eminingi, babe nekhono lokuzahlulela futhi bakhethe okufanele china umshini wokujova ukukhiqiza. Noma kunjalo, kwezinye izimo, ikhasimende lingadinga usizo lomkhiqizi ekunqumeni ukuthi yimuphi umshini wokubumba umjovo ozowusebenzisa, noma ngisho nekhasimende lingase libe nesampula noma umqondo womkhiqizo bese libuza umenzi. ukuthi umshini ungakhiqizwa noma iyiphi imodeli eqhathaniswa.

Ngaphezu kwalokho, eminye imikhiqizo ekhethekile ingase idinge amadivaysi akhethekile njengama-accumulators okucindezela, izihibe ezivaliwe, ukuminyaniswa komjovo, njll., ukuze ikhiqizwe ngempumelelo. Kungabonakala ukuthi indlela yokunquma umshini wokubumba umjovo ofanele ozokhiqizwa kuwumbuzo obaluleke kakhulu. Ulwazi olulandelayo luhlinzekelwe ukusiza abafundi.

Izinto ezibalulekile ezithinta ngokuvamile ukukhethwa komshini womjovo zihlanganisa isikhunta, imikhiqizo, amapulasitiki, Izidingo zokubumba, njll. Ngakho-ke, ulwazi olulandelayo kufanele luqoqwe noma lutholakale ngaphambi kokukhetha:

◆ Isikhunta ubungako (ububanzi, ukuphakama, ubukhulu), isisindo, umklamo okhethekile, njll. ;

◆ Uhlobo kanye nenani lepulasitiki esetshenzisiwe (impahla eyodwa eluhlaza noma amapulasitiki amaningana);

Usayizi wokubukeka (ubude, ububanzi, ukuphakama, ubukhulu), isisindo, njll. umjovo olubunjiwe umkhiqizo;

Ngemva kokuthola ulwazi olungenhla, ungalandela izinyathelo ezingezansi ukuze ukhethe umshini womjovo ofanelekile:1. Khetha imodeli efanele: imodeli nochungechunge kuncike kumkhiqizo kanye nepulasitiki. Ngoba kunezinhlobo eziningi ze-china imishini yokujova, kuyadingeka ukucacisa kahle ukuthi yikuphi umshini wokubumba umjovo noma uchungechunge umkhiqizo okufanele wenziwe ekuqaleni, njengezinto ezivamile ze-thermoplastic noma ze-bakelite noma izinto zokusetshenziswa ze-PET. Umbala, imibala emibili, i-multicolor, i-interlayer noma umbala oxubekile, njll. Ngaphezu kwalokho, eminye imikhiqizo idinga izimo ezinjengokuqina okuphezulu (iluphu evaliwe), ukunemba okuphezulu, umlilo ophezulu kakhulu, ukucindezela okukhulu kokudubula noma ukukhiqizwa okusheshayo (ama-multi-loop), futhi uchungechunge olufanele kufanele futhi kukhethwe ukukhiqizwa.

2. Kungabekwa phansi: usayizi isikhunta inquma ukuthi “ikholomu enkulu ngaphakathi kwebanga”, “ukujiya kwesikhunta”, “ubuncane bosayizi wesikhunta” futhi “usayizi wepuleti lesikhunta” zomshini zifanelekile ukuqinisekisa ukuthi isikhunta singabekwa phansi.

◆ I ububanzi nokuphakama kwesikhunta kufanele ibe ngaphansi noma okungenani ibe nohlangothi olulodwa lube luncane kunebanga langaphakathi lekholomu enkulu;

◆ Ububanzi nobude besikhunta kufanele kuhambisane nosayizi omncane wokubumba onconywa umshini wokubumba umjovo futhi kuncane kakhulu..

3. Ingatholakala: isikhunta kanye nomkhiqizo wokugcina kunquma ukuthi “isikhunta imivimbo yokuvula” futhi “imivimbo yesikhunta” zanele ukususa umkhiqizo wokugcina.

◆ Ukuvulwa kokuvula kwesikhunta kufanele kube okungenani kabili ukuphakama komkhiqizo wokugcina ekuqondeni kokuvula nokuvalwa kwesikhunta., nobude bokubunjwa kufanele bufakwe;

4. Iyunithi yokubopha engakhiya umshini womjovo kufanele inikeze okwanele “amandla okubopha” ukuvimbela isikhunta ekuvulekeni. Ukubalwa kwemfuneko ye-clamping force imi kanje:

◆Bala indawo ehlongozwayo yomkhiqizo oqediwe ohlangothini lwesikhunta sokushintsha kusuka kusayizi wokubukeka womkhiqizo oqediwe.;

◆ Amandla okusekela isikhunta = indawo ehlongozwayo yomkhiqizo oqediwe ekuqondeni kwesikhunta sokushintsha (cm2) × inani lezimbobo zesikhunta × ukucindezela kusikhunta (kg / cm2);

◆Ingcindezi ekubunjeni iyahlukahluka kuye ngezinto ezingavuthiwe, futhi impahla eluhlaza ejwayelekile ingu-350 ~ 400kg/cm2;

◆I-clamping force yomshini kumele ibe nkulu kunamandla okubamba, nangenxa yokuphepha, amandla okubamba komshini ngokuvamile 1.17 izikhathi eziphakeme kunamandla okubamba.

5. Isibhamu esigcwele: Nquma okudingekayo “umthamo womjovo” kusukela kusisindo somkhiqizo oqediwe kanye nenani lezimbobo zesikhunta bese ukhetha okufanele “isikulufa ubukhulu”.

◆Inani lemigodi yesikhunta (isikhunta esisodwa kanye nezimbotshana eziningana) kufanele kubhekwe lapho kubalwa isisindo somkhiqizo ophelile;

◆Ukuze kube nozinzo, umthamo womjovo kufanele ube 1.35 izikhathi isisindo somkhiqizo ophelile, leyo, isisindo somkhiqizo ophelile kufanele sibe ngaphakathi 75% yevolumu yomjovo.

6. Umjovo omuhle: izimo ze “isikulufa kokucindezelwa isilinganiso” futhi “ingcindezi yomjovo” kunqunywa ngepulasitiki. Amanye amaplastiki wobunjiniyela adinga ukucindezelwa komjovo ophakeme kanye nomklamo ofanele wesikulufu sokuminyaniswa ukuze ube nemiphumela emihle yokubumba. Ngakho-ke, ukuze umkhiqizo oqediwe udutshulwe kangcono, izidingo zengcindezi yomjovo kanye nezinkinga zesilinganiso sokuminyanisa nazo kufanele zicatshangelwe lapho kukhethwa isikulufu. .

7.7. Ukudubula ngokushesha: kanye nokuqinisekiswa kwe “isivinini sokudubula”. Eminye imikhiqizo eqediwe idinga isilinganiso somjovo ophakeme nomjovo osheshayo wokubumba okuzinzile, njenge-ultra-thin imikhiqizo eqediwe. Esimweni esinjalo, kungadingeka ukuqinisekisa ukuthi isilinganiso somjovo kanye nesilinganiso somjovo womshini sanele, nokuthi ngabe idinga ukufakelwa ama-accumulators engcindezi, i-loop-control control namanye amadivayisi. Sengisho nje, ngaphansi kwezimo ezifanayo, isikulufa esingahlinzeka ngomfutho ophakeme womjovo ngokuvamile sinesivinini sokudubula esiphansi, Ngokuphambene nalokho, isikulufa esinganikeza ingcindezi yomjovo ophansi ngokuvamile sinejubane eliphakeme lokudubula. Ngakho-ke, lapho ukhetha ububanzi besikulufu, ivolumu yomjovo, ingcindezi yomjovo kanye nesilinganiso somjovo (isivinini somjovo) idinga ukucatshangelwa futhi ikhethwe.

Ngaphezu kwalokho, idizayini enezinhlobonhlobo eziningi nayo ingasetshenziselwa ukunciphisa isikhathi sokubumba ngezenzo ezihlanganisiwe ezihlanganisiwe. Ngemuva kwezinyathelo ezingenhla, ngokomthetho, umshini wokubumba umjovo ohlangabezana nezidingo unganqunywa, kodwa kunezindaba ezikhethekile okufanele zibhekwe:

◆Inkinga yokufanisa usayizi:

Ngaphansi kwezimo ezithile ezikhethekile, isikhunta sekhasimende noma umkhiqizo ungase ube nosayizi omncane wesikhunta kodwa inani elikhulu lokudubula, noma usayizi omkhulu wesikhunta kodwa inani elincane lokudubula. Esimweni esinjalo, imininingwane ejwayelekile ebekwe umenzi kungenzeka ingatholakali. Ukuze uhlangabezane nezidingo zamakhasimende, okuthiwa “ukufanisa usayizi” kumele kwenziwe, leyo, “udonga olukhulu isibhamu esincane” noma “udonga oluncane isibhamu esikhulu”. Okuthiwa “udonga olukhulu nomjovo omncane” ibhekisela kuyunithi yokuqala yokufa esezingeni elivamile elinesikulufu somjovo esincane. Ngokuphambene nalokho, i “udonga oluncane kanye nomjovo omkhulu” ibhekisela kuyunithi yokuqala evamile yokubopha ngesikulufu somjovo esikhulu. Kunjalo, kungase kube amazinga amaningana umehluko phakathi isikhunta clamping kanye umjovo.

Ekusetshenzisweni kwangempela, amakhasimende amaningi azocela ukuthenga lokho okubizwa “umshini wejubane eliphezulu” noma “umshini osheshayo”. Sengisho nje, ngaphezu kwezidingo zomkhiqizo ngokwawo, iningi lemigomo iwukufinyeza umjikelezo wokubumba nokwandisa okukhiphayo ngesikhathi seyunithi, ngaleyo ndlela kunciphisa izindleko zokukhiqiza kanye nokwenza ngcono ukuncintisana. Ngokuvamile, ukufeza inhloso eshiwo ngenhla, kunezindlela eziningana:

1. Sheshisa i- isivinini somjovo: ukwandisa motor kanye futha, noma wengeze i-accumulator yokucindezela (okungcono ukulawulwa kweluphu evaliwe);
2. Sheshisa isivinini sokudla: ukwandisa motor motor kanye futha, noma wehlise i-hydraulic motor yokudla ukusheshisa isivinini sesikulufu;
3. Uhlelo lwe-Multi-loop: yamukela idizayini eyiluphu ephindwe kabili noma eyiluphu emithathu ukuze yenze izenzo ezihlanganisiwe kanyekanye ukuze kufinyezwe isikhathi sokubumba;
4. Khulisa umzila wamanzi wesikhunta ukuze uthuthukise ukusebenza kahle kokupholisa kwesikhunta.
