Lapho ukhetha injini, ungakhetha kanjani amandla kanye ne-torque?

Amandla emoto kufanele akhethwe ngokuya ngamandla adingwa umshini wokukhiqiza, bese uzama ukwenza injini isebenze ngaphansi komthwalo olinganiselwe.Lapho ukhetha, kufanele unake amaphuzu amabili alandelayo:

① Uma amandla emoto emancane kakhulu.Kuzoba khona "inqola encane edonswa ngamahhashi", okubangela ukuthi injini igcwale isikhathi eside.I-insulation yayo yonakele ngenxa yokushisa.Ngisho nemoto ishe yaphela.

② Uma amandla emoto emakhulu kakhulu.Kuzoba khona "inqola enkulu edonswa amahhashi".Amandla ayo omshini okukhiphayo awakwazi ukusetshenziswa ngokugcwele, futhi isici samandla nokusebenza kahle akuphezulu, okungeyona nje into engathandeki kubasebenzisi kanye negridi yamandla.Futhi kuzodala nokumoshakala kukagesi.

Okuvame ukusetshenziswa kakhulu indlela yokufanisa ukukhetha amandla enjini.Okubizwa ngokuthi isifaniso.Iqhathaniswa namandla enjini kagesi esetshenziswa emishinini yokukhiqiza efanayo.

Indlela eqondile yilena: ukuqonda injini yamandla esetshenziswa imishini yokukhiqiza efanayo yale yunithi noma amanye amayunithi aseduze, bese ukhetha injini yamandla afanayo ukuze wenze ukuhlola.Inhloso yokuhlolwa kokuhlola ukuqinisekisa ukuthi injini ekhethiwe ifana nomshini wokukhiqiza.

Indlela yokuqinisekisa ithi: yenza injini ishayele umshini wokukhiqiza ozosebenza, ulinganise ukusebenza kwemoto nge-ammeter ye-clamp, futhi uqhathanise umthamo wamanje olinganisiwe omakwe ku-nameplate yemoto.Uma ukusebenza kwangempela komshini wamandla kagesi akufani kakhulu nesilinganiso samanje esimakwe embendeni.Kubonisa ukuthi amandla emoto ekhethiwe afanelekile.Uma ukusebenza kwangempela kwemoto kucishe kube ngama-70% aphansi kunesilinganiso samanje esimakwe ku-nameplate.Kubonisa ukuthi amandla emoto makhulu kakhulu, futhi injini enamandla amancane kufanele ishintshwe.Uma isilinganiso sokusebenza semoto singaphezu kuka-40% esikhulu kunesamanje esilinganiselwe esimakwe ku-nameplate.Kubonisa ukuthi amandla emoto mancane kakhulu, futhi injini enamandla amakhulu kufanele ishintshwe.

Ifanele ukuqhutshwa okufanayo kobudlelwane phakathi kwamandla alinganiselwe, isivinini esilinganiselwe kanye ne-torque elinganiselwe ye-servo motor, kodwa inani langempela le-torque elilinganiselwe kufanele lisekelwe esilinganisweni sangempela.Ngenxa yenkinga yokuguqulwa kwamandla, amanani ayisisekelo ayafana, futhi kuzoba nokwehla okucashile.

isakhiwo motor

Ngezizathu zesakhiwo, ama-DC motors anemibi elandelayo:

(1) Amabhulashi nabagibeli badinga ukushintshwa njalo, ukunakekelwa kunzima, futhi impilo yesevisi ifushane;(2) Ngenxa yezinhlansi zokushintsha kwemoto ye-DC, kunzima ukusebenzisa ezindaweni ezinokhahlo ezinamagesi avuthayo neziqhumane;(3) Isakhiwo siyinkimbinkimbi, kunzima ukwenza imoto ye-DC enamandla amakhulu, isivinini esikhulu kanye nomthamo omkhulu.

Uma kuqhathaniswa nama-DC motors, ama-AC motors anezinzuzo ezilandelayo:

(1)Isakhiwo esiqinile, ukusebenza okuthembekile, ukugcinwa okulula;(2) Ayikho inhlansi yokuhamba, futhi ingasetshenziswa ezindaweni ezinokhahlo ezinamagesi avuthayo neziqhumane;(3) Kulula ukwenza injini ye-AC enamandla amakhulu, enesivinini esikhulu futhi enamandla kagesi.

Ngakho-ke, isikhathi eside, abantu banethemba lokushintsha injini ye-DC ngenjini ye-AC eshintshwa isivinini ezikhathini eziningi, futhi umsebenzi omningi wocwaningo nokuthuthukiswa uye wenziwa ekulawuleni isivinini se-AC motor.Kodwa-ke, kuze kube ngama-1970s, ucwaningo nokuthuthukiswa kohlelo lokulawula isivinini se-AC alukwazanga ukuthola imiphumela eyanelisa ngempela, ebeka umkhawulo ekudumeni nasekusetshenzisweni kohlelo lokulawula isivinini se-AC.Kungalesi sizathu futhi ukuthi ama-baffle nama-valve kufanele asetshenziselwe ukulungisa isivinini somoya nokugeleza ezinhlelweni zokushayela ugesi ezifana namafeni namaphampu amanzi asetshenziswa kakhulu ekukhiqizeni izimboni futhi adinga ukulawula isivinini.Le ndlela ayigcini nje ukwandisa ubunzima besistimu, kodwa futhi iphumela ekusetshenzisweni kwamandla.
