Abahlinzeki bedivayisi yempendulo yamandla bakukhumbuza ukuthi iziguquli zefrikhwensi zisetshenziswa kakhulu ekukhiqizweni kokulawulwa kwezimboni. Ahlukaniswe abe ama-low-voltage frequency converters kanye nama-medium high voltage frequency converters ngokuya ngamazinga kagesi, futhi inhloso kanye nezidingo zokusetshenziswa kwawo ziyahlukahluka ezimbonini ezahlukene. Uyazazi izinhlelo ezintathu ezinkulu zokuguqula ama-frequency converters?
1. Isetshenziselwa imithwalo yamandla engashintshi
Ngenxa ye-torque ephezulu yokuqala yezimpawu ezithile zomthwalo, imishini okunzima ukuyiqala, njengama-extruder, imishini yokuhlanza, ama-spin dryers, ama-mixers, imishini yokumboza, ama-mixers, amafeni amakhulu, amaphampu amanzi, ama-Roots blowers, njll., konke kungaqalwa kahle. Lokhu kusebenza kangcono kunokujwayelekile ukukhulisa imvamisa yokuqala yokuqala. Ngokusebenzisa le ndlela futhi uyihlanganise nezinyathelo zokushintsha kusukela emthwalweni osindayo ukuya ekulayisheni okulula, ukuvikelwa kwamanje kunganyuswa kuze kube senani eliphakeme, futhi cishe yonke imishini ingaqalwa. Ngakho-ke, ukunciphisa imvamisa yesisekelo ukwandisa i-torque yokuqala kuyindlela ephumelela kakhulu futhi elula.
2. Isetshenziselwa ukubeka nokucubungula isignali
Izintambo ezivikelekile kufanele zisetshenziselwe isignali kanye nemigqa yokulawula ukuvimbela ukuphazamiseka. Uma umugqa umude, njengokugxuma kwebanga okungamamitha ayi-100, i-wire cross-section kufanele inwetshwe. Izintambo zesiginali nokulawula akufanele zibekwe endaweni efanayo yekhebula noma ibhuloho njengezintambo zikagesi ukuze kugwenywe ukugxambukela. Kungcono ukuwabeka emiseleni ukuze afaneleke kangcono.
3. Izindlela ezisetshenziswa ekunikezeni amanzi ngomfutho njalo
Namuhla, indlela yokunikezwa kwamanzi okucindezelwa njalo ivame ukusetshenziselwa ukusetshenziswa kwamanzi: amaphampu amanzi amaningi axhunywe ngokuhambisana ukuze anikeze amanzi acindezela njalo. Kunezikimu ezimbili ezivamile zokuguqulwa kobuchwepheshe bokuphakela amanzi ngomfutho oguquguqukayo:
Yonga utshalomali lokuqala, kodwa umphumela wokonga amandla mubi. Uma uqala, qala uqale isiguquli sefrikhwensi siye ku-50 Hz, bese uqala imvamisa yamandla, bese ushintshela kulawulo lokonga amandla. Ohlelweni lokuhlinzeka ngamanzi, yiphampu yamanzi kuphela eqhutshwa isiguquli semvamisa enomfutho ophansi kancane, futhi kuba nezinxushunxushu nokulahlekelwa ohlelweni.
Ukutshalwa kwezimali kukhulu uma kuqhathaniswa, kodwa konga amandla angu-20% ngaphezu kuka-(1). Ukucindezela kwepompo ye-Yuantai kuyavumelana, akukho ukulahlekelwa kwesiphithiphithi, futhi umphumela ungcono.
Lapho amaphampu amanzi amaningi exhunywe ngokufana ukuze anikeze amanzi ngomfutho njalo, indlela yokuxhuma yochungechunge lwesignali isetshenziswa ngenzwa eyodwa kuphela, enezinzuzo ezilandelayo:
Yonga izindleko. Isethi eyodwa nje yezinzwa kanye ne-PID;
Njengoba kunesignali eyodwa kuphela yokulawula, imvamisa yokuphuma iyahambisana, okungukuthi, imvamisa efanayo, ngakho-ke ukucindezela nakho kuyavumelana, futhi akukho ukulahlekelwa kwesiphithiphithi;
Okuzuzisa kakhulu ukuthi ngenxa yokuthi uhlelo lunesignali eyodwa kuphela yokulawula, ngisho noma amaphampu amathathu afakwe okokufaka okuhlukene, imvamisa yokusebenza iyafana futhi ingcindezi nayo iyafana. Lokhu kuphumela ekulahlekelweni kwezinxushunxushu, okusho ukuthi ukulahlekelwa kuncishisiwe, ngaleyo ndlela kuzuzwe umphumela ongcono kakhulu wokonga amandla.
