Abahlinzeki beziguquli ezikhethekile zamafrikhwensi amakheshi bakukhumbuza ukuthi ukulawulwa kwesivinini kwesiguquli semvamisa kungafinyelela ukusheshisa okuqhubekayo nokulawulwa kokunciphisa ikheshi, okungavimbela ngempumelelo izingozi ezinjengokusongwa nokungavulwa kwekheshi; Ukulawulwa kwejubane kwesiguquli semvamisa kungaphinda kuzuze ukuqala okuthambile kwemoto, kususe ukusetshenziswa kwamandla okubangelwa ukumelana nochungechunge lwe-rotor futhi kube nomthelela obaluleke kakhulu wokonga amandla.
Isakhiwo sesistimu yokulawula isivinini sokuguqulwa kwemvamisa yekheshi
Isistimu yokulawula isivinini sokuguqulwa kwemvamisa ye-hoist ikakhulukazi yakhiwe isiguquli semvamisa; Ukulawula ukuhamba; Ukulawula ukusebenza; Ihlanganiswe nokubhuleka kokusetshenziswa kwamandla nokubamba ibhuleki, isiguquli sefrikhwensi sifinyelela ngokuyinhloko ukulawulwa kwesivinini esishintshashintshayo sokuphakamisa nokwehlisa i-hoist; Ukulawulwa kohambo ikakhulukazi kunikeza isilawuli sokuhamba esinembayo sokudluliswa, ukupaka, kanye nokubhuleka kwe-hoist; Ukulawulwa kokusebenza kuqeda ngokuyinhloko ukuqala kokuphakamisa, ukwehlisa isiqalo, ukusetha kabusha iphutha, ukubhuleka okuphuthumayo nezinye izilawuli zokusebenza kwe-hoist; Ukusebenzisa amandla amabhuleki nokubamba amabhuleki ikakhulukazi kuzuza ukulawula ukupaka kwekheshi.
Isimiso sokulawulwa kwesivinini esishintshashintshayo
Ekusetshenzisweni kwesistimu ye-hoist, isiguquli sefrikhwensi senza ukulawula isivinini esishintshashintshayo sokusheshisa njalo, ukulawulwa kwesivinini esishintshashintshayo sokuqala, ukwehla okungaguquki, ukulawulwa kwesivinini esishintshashintshayo sokuma, nokulawula isivinini esishintshashintshayo sokusebenza. Ukulawulwa kwejubane lokuvama okuguquguqukayo kulungisa isivinini semoto ngokushintsha imvamisa yokunikezwa kwamandla okokufaka, ngakho-ke uhla lokulawula isivinini lubanzi kakhulu. Ngokuvamile, iziguquli zefrikhwensi zingafinyelela ku-0-400Hz, futhi ukunemba kokulawula imvamisa ngokuvamile kungu-0.01Hz, okungahlangabezana kahle nezidingo zokusheshisa okuqhubekayo nokwehla okuqhubekayo kokulawula isivinini esingenasinyathelo se-hoist. Ngakho-ke, ngemuva kokusebenzisa isiguquli semvamisa, injini ingafinyelela isiqalo esithambile sangempela kanye nokulawulwa kwejubane elibushelelezi. Ukulawulwa kwejubane le-frequency drive eguquguqukayo kuhlukile kunokulawulwa kwejubane lokumelana nochungechunge lwe-rotor, okunciphisa izinga lokushelela, kuthuthukise isici samandla wesekethe, futhi kungakhipha i-torque engaguquki. Amandla okukhiphayo ayahlukahluka ngesivinini, ngakho anomphumela omuhle wokonga amandla. Ngakolunye uhlangothi, isiguquli se-frequency singase futhi siguqule kalula i-torque yokuphumayo (okungukuthi ukulungisa ijika lesinxephezelo se-torque), ukusheshisa kanye nesikhathi sokunciphisa, imvamisa eqondiwe, amaza omkhawulo aphezulu naphansi, njll. ngokusebenzisa isofthiwe. Isiguquli sefrikhwensi siphinde sibe nemisebenzi enamandla ehambisanayo, futhi singahlanganisa imisebenzi, setha imingcele (shintsha), futhi silungise isivinini ngokuguquguqukayo ngokuya ngezidingo zokusetshenziswa. Isiguquli sefrikhwensi singaphinda silawulwe ngamabhulokhi wetheminali ukuze kuzuzwe ukulawulwa kwesivinini sezigaba eziningi se-stroke. Umfanekiso wesi-2 uwumdwebo wohlelo lokusheshisa okungaguquki kanye nenqubo yokulawula isivinini sokwehla njalo kwesiguquli semvamisa. Izinqubo zokusheshisa nokunciphisa zingashintshwa ngendlela eguquguqukayo, okuzuzisa kakhulu ukuvimbela ukugoqa, ukuqaqa, ukwehla, njll. kwe-hoist.
I-variable frequency regulation ayigcini nje ngokulawula unhlangothi, kodwa futhi nokulawula amabhuleki
Ukulawula ukuhamba - kuwumdwebo wohlelo lwenqubo yokuphakamisa nokwehlisa ikheshi. Ukulawulwa kokuhamba kuhlukaniswe izinqubo ezimbili, enye i-stroke yokuphakamisa phambili kanti enye i-stroke ehlehlisayo ehlehlayo. Ukulawula ukuhamba kuhlukanisa ikakhulukazi inqubo yokuphakamisa ikheshi ngezikhawu zokuhamba ezihlukene. Ngokwesimo sangempela sesikhawu sohambo ngasinye, ukulawulwa kwesivinini sokuguqulwa kwemvamisa okuhlukile kungasetshenziswa ukulawula isivinini sokuphakamisa ikheshi. Ukulawula ukuhamba akulawuli kuphela ukulawulwa kwesivinini sokuguqulwa kwemvamisa yayo yonke inqubo yokuphakamisa i-lifti, kodwa futhi kulawula inqubo yokupaka neyokubhuleka yekheshi. Ukulawulwa kohambo kungavimbela ngokuphumelelayo izingozi ezinjengokujika, ukuqaqa, ukuchezuka, nokugingqika kwendawo ephakamayo, kuyenze ifaneleke ngokukhethekile imishayo ethambekele ekhethekile enamajika nezimfoloko.
Ukulawulwa kohambo kusetshenziswa ngokusekelwe endaweni yokuphakamisa (isikhathi sokuvakasha) sekheshi. Isilawuli sokuhamba siguqula indawo yohambo sibe isignali yokushintsha futhi senza ulawulo lokuguqulwa kwefrikhwensi yezigaba eziningi, ulawulo lokupaka, nokulawula amabhuleki ngokusebenzisa itheminali yokulawula yesiguquli sefrikhwensi.
Ukulawula amabhuleki - Ukusetshenziswa okuphephile kwe-hoist kudinga uhlelo oluhle lokulawula ukubhuleka nokubhuleka, ngokuvamile oluhlanganisa ukusebenzisa amandla okubhuleka nokubamba ibhuleki. I-braking yokusetshenziswa kwamandla isebenzisa amandla okuvuselela kabusha akhiqizwa yi-inertia ye-hoist ngesikhathi sokuncipha kanye ne-descent stroke for braking. Isiguquli sefrikhwensi sisebenzisa amayunithi okusebenzisa amandla ukuze sizuze ukubhuleka kokusetshenziswa kwamandla, okuwuhlobo lokubhuleka okuthambile okungavimbela ngempumelelo umthelela wemishini kanye nokushelela ngokushesha. Ukuze kugwenywe izingozi ezifana nokuphuma emzileni, i-hoist ivalwe ngebhuleki. Ibhuleki livame ukusetshenziswa uma upaka. Lapho imoto ifika endaweni yokupaka, isilawuli sohambo sithumela isignali yokuma kusiguquli sefrikhwensi, futhi ngesikhathi esifanayo, sithumela isignali yokulawula ibhuleki kubhuleki ukuze kusetshenziswe ibhuleki. Uma kwenzeka kuba nengozi noma ezinye izingozi, isilawuli sokusebenza sisebenzisa ibhuleki eliphuthumayo.
