Iimfuno zenkqubo yomatshini omkhulu wokunitha ojikelezayo
(1) Kuyafuneka ukuba isiguquli se-frequency converter sinokuchasana okunamandla kokusingqongileyo.Ngenxa yokushisa okuphezulu kwendawo yokusebenza kwendawo kunye ne-cotton wadding, i-fan yokupholisa kulula ukuvalelwa, yonakaliswe kwaye umgodi wokupholisa uvaliwe.
(2) I-Flexible inching function iyadingeka, amaqhosha e-inching afakwe kwiindawo ezininzi zezixhobo, kwaye i-converter frequency kufuneka iphendule ngokukhawuleza.
(3) Ngokubhekiselele kulawulo lwesantya, izantya ezintathu ziyafuneka.Enye isantya sokubaleka, sikholisa ukuba malunga ne-6Hz;Okwesibini sisantya esiqhelekileyo sokuluka, esona santya siphezulu sinokufikelela kuma-70Hz;Okwesithathu, umsebenzi wokuqokelela ilaphu ngesantya esisezantsi ufuna ukuphindaphinda malunga ne-20Hz.
(4) Ngexesha lokusebenza komatshini omkhulu ojikelezayo, akuvumelekanga ngokupheleleyo ukubuyisela umva kunye nokujikeleza i-motor, ngaphandle koko inaliti yombhede wenaliti iya kugoba okanye yaphuke.Ukuba ngumatshini omkhulu ojikelezayo kunye neebheringi zesigaba esisodwa, akunakuqwalaselwa.Ukuba ukujikeleza phambili kunye nokubuyisela umva kwenkqubo kuxhomekeke ngokupheleleyo ekujikelezeni phambili kunye nokubuyisela umva kwemoto, kwelinye icala, kuyimfuneko ukunqanda ukujikeleza umva, kwaye kwelinye icala, kuyimfuneko ukuseta i-DC braking ukuphelisa ukujikeleza. .
Imfuneko yobugcisa
Umzi-mveliso woMatshini wokunitha uneemfuno ezilula kulawulo lomsebenzi wesiguquli samaza.Ngokuqhelekileyo, ukuqala kunye nokumisa kulawulwa yi-terminal, kunye ne-frequency enikiweyo yobuninzi be-analog okanye i-frequency enikeziweyo yesantya se-multistage sisetyenziswa.I-intshing okanye i-low-speed operation kufuneka ikhawuleze, ngoko ke i-converter frequency iyadingeka ukuze ikwazi ukulawula i-torque ephantsi ye-motor.Ngokubanzi, imowudi ye-V / F ye-frequency converter inokuhlangabezana neemfuno zokusetyenziswa komatshini omkhulu ojikelezayo.
Isisombululo sethu kukuba:
EC590 frequency converter, amandla yi 4kW
Iinzuzo zemveliso:
1. Ukukhawuleza kohlobo lwe-S kunye nokunciphisa isiqalo esigudileyo kunye nokuyeka.
2. Imowudi yokulawula i-Magnetic flux vector, i-frequency ephantsi, i-torque enkulu, ukuphendula ngokukhawuleza.
3. I-Deceleration plus DC braking function, ukuvala okuzinzile kunye nokunyathela.
4. Umsebenzi wokuthintela ukujikeleza umva wamkelwa ukuphepha ukuphuka kwenaliti okubangelwa ukujikeleza okujikelezayo kwezixhobo.
5. Uyilo oluhle lokutshatyalaliswa kobushushu lunokuhlangabezana ngokupheleleyo nokusebenza kwexesha elide lezixhobo kwindawo yokushisa okuphezulu.
