Pamene kugwiritsa ntchito mphamvu moyenera komanso kumasuka kwa okwera kukukulirakulira m'machitidwe amakono oyendera, ukadaulo wa variable frequency drive (VFD) wakhala njira yotchuka yosinthira ma escalator. Dongosolo la Hitachi EasyDrive VFD limapereka kuwongolera liwiro mwanzeru, kuchepetsa kugwiritsa ntchito mphamvu, komanso kudalirika kwa magwiridwe antchito a escalator.
Yankho la Anzeru la Escalator Control
Dongosolo la Hitachi EasyDrive VFD limagwiritsa ntchito masensa a infrared omwe amaikidwa pamalo okwera komanso otsika a escalator.
Wokwera akayandikira kapena kukwera pa escalator, sensa ya infrared imayatsidwa ndipo imatumiza chizindikiro ku EasyDrive VFD. Inverter nthawi yomweyo imafulumizitsa escalator kufika pa liwiro lake lokhazikika, kuonetsetsa kuti mayendedwe ake ndi osavuta komanso omasuka.
Munthawi zomwe anthu amadutsa pang'ono kapena osayenda konse, makinawa amasinthira okha kukhala liwiro lotsika. Njira yowongolera yanzeru iyi imachepetsa kwambiri kugwiritsa ntchito mphamvu pamene ikusunga okonzeka kugwiritsidwa ntchito ndi anthu.
Pa ntchito yokwera ndi kutsika, makina owongolera amagwiritsa ntchito chitetezo cholumikizana kuti zitsimikizire kuti ntchitoyo ndi yotetezeka komanso yodalirika. Choletsa mabuleki chimayikidwanso kuti chizitenga mphamvu yochulukirapo yomwe imapangidwa panthawi yochepetsa mphamvu yamagetsi komanso yotsika.
Ubwino Waukulu wa EasyDrive VFD System
Mphamvu Yoyambira Yotsika Liwiro
Ikugwira ntchito mu open-loop vector control mode, EasyDrive VFD imapereka magwiridwe antchito abwino kwambiri komanso kuyankha mwachangu.
Pakuyamba kwa 0.5Hz, drive imatha kupereka mphamvu yokwana 150% ya mphamvu yovomerezeka, kukwaniritsa zofunikira zonse za ma escalator.
Kuyamba Mofewa Kuti Mutetezeke Kwambiri
Ntchito yoyambira yofewa yomangidwa mkati imachepetsa kukwera kwa mphamvu zamagetsi panthawi yoyambira injini, kuchepetsa kupsinjika kwa magetsi pa injini komanso makina opangira magetsi.
Mphamvu Yowonjezera
EasyDrive VFD imagwira ntchito ngati capacitive load, kuthandiza kukonza mphamvu ya injini ndikuchepetsa kutayika kwa mphamvu yogwira ntchito, zomwe zimapangitsa kuti makina onse azigwira ntchito bwino.
Chitetezo Chonse
Chitetezo cha mthupi chimaphatikizapo zinthu zambiri, kuphatikizapo:
- · Chitetezo cha mphepo yowonjezereka
- · Chitetezo cha overvoltage
- · Chitetezo cha katundu wambiri
- · Chitetezo ku kutentha kwambiri
- · Ntchito zotulutsa alamu zolakwika
Zinthu zimenezi zimathandiza kuonetsetsa kuti escalator ikugwira ntchito bwino komanso modalirika pa ntchito zosiyanasiyana.
Kuchepa kwa Kuvala kwa Makina
Ma escalator akale nthawi zambiri amapitiliza kugwira ntchito pa liwiro lathunthu ngakhale palibe okwera. Ndi njira ya EasyDrive VFD, escalator imayenda pa liwiro lotsika nthawi yopuma, zomwe zimachepetsa kwambiri kuwonongeka kwa unyolo, ma sprockets, ma bearing, ndi zida zina zamakanika.
Izi sizimangowonjezera nthawi yogwiritsira ntchito zida komanso zimachepetsa ndalama zokonzera.
Njira Zogwirira Ntchito Zosinthasintha
Dongosolo la EasyDrive VFD limathandizira zonse ziwiri:
- · Makina ogwiritsira ntchito okha
- · Njira yogwiritsira ntchito pamanja
Ngati vuto la VFD lachitika, makinawo amatha kusintha okha kuti agwire ntchito yamagetsi pafupipafupi, zomwe zimathandiza kuti escalator ipitirize kunyamula anthu ndikuchepetsa kusokonezeka kwa ntchito.
Zofunikira pakugwiritsa ntchito ma escalator
Ma escalator ambiri a Hitachi amagwiritsa ntchito ma mota a AC othamanga limodzi ndi makina otumizira ma transmission oyendetsedwa ndi unyolo. Mwachikhalidwe, ma escalator amenewa amagwira ntchito mosalekeza pa liwiro lovomerezeka la pafupifupi 0.5 m/s, mosasamala kanthu za kuchuluka kwa anthu omwe akuyenda.
Njira yogwiritsira ntchito nthawi zambiri imabweretsa zotsatirazi:
- · Kugwiritsa ntchito mphamvu zambiri
- · Kuchuluka kwa kuvala kwa makina
- · Kuchepetsa nthawi ya moyo wa chinthu
Mwa kuphatikiza njira ya EasyDrive VFD, ma escalator amatha kusintha liwiro logwirira ntchito mwanzeru malinga ndi kufunikira kwa okwera. Akapezeka okwera, escalator imathamanga bwino mpaka liwiro lonse logwira ntchito. Munthawi yopanda ntchito, imachepetsa liwiro lokha, zomwe zimapangitsa kuti zida zisunge mphamvu komanso kukhala ndi nthawi yayitali yogwiritsira ntchito.
Mapeto
Dongosolo la Hitachi EasyDrive VFD limapereka yankho lothandiza pakukweza mphamvu ndi mapulojekiti amakono a escalator. Kudzera mu kuwongolera liwiro mwanzeru, magwiridwe antchito oyambira pang'onopang'ono, magwiridwe antchito oteteza, komanso njira zosungira zokha, dongosololi limawonjezera chitetezo, chitonthozo cha okwera, komanso magwiridwe antchito abwino pomwe limachepetsa ndalama zokonzera.
Mukufuna njira zamakono zokwezera ma escalator, kukweza kwa VFD, kapena kusintha zida zokwezera ma escalator? YuanQi imapereka zinthu zodalirika, chithandizo chaukadaulo chaukadaulo, komanso njira zoyimilira zonse za ma escalator ndi ma elevator padziko lonse lapansi.
