Cholinga chathu chachikulu ndikupatsa ogula athu ubale wodalirika komanso wodalirika wamakampani, kupereka chisamaliro chaumwini kwa onse a Chinese Professional China Negative Power AC Drive Wholesale 5.5kw for Small Automatic Machines Frequency Converter VFD, Tsopano tapanga dzina lodziwika bwino pakati pa ambiri. makasitomala. Ubwino & kasitomala woyamba nthawi zambiri amakhala kufunafuna kwathu kosalekeza. Sitingayesere kuyesa kuti tithandizire kupeza mayankho abwino kwambiri. Yembekezerani mgwirizano wanthawi yayitali komanso zabwino zonse!
Cholinga chathu chachikulu ndikupatsa ogula athu ubale wodalirika komanso wodalirika wamakampani, kupereka chisamaliro chaumwini kwa onseAC Inverter, China Inverter, Ndondomeko yathu ya Kampani ndi "ubwino woyamba, kukhala wabwinoko ndi wamphamvu, chitukuko chokhazikika" . Zolinga zathu ndi "za anthu, makasitomala, antchito, othandizana nawo ndi mabizinesi kuti apeze phindu loyenera". Tikufuna kuyanjana ndi opanga zida zosiyanasiyana zamagalimoto, malo ogulitsira, ochita nawo magalimoto, kenako ndikupanga tsogolo labwino! Zikomo chifukwa chopatula nthawi yoyang'ana tsamba lathu ndipo tikulandila malingaliro aliwonse omwe mungakhale nawo omwe angatithandize kukonza tsamba lathu.
Injection Molding Machine Hydraulic System
Kapangidwe ka Hydraulic Servo System
Pambuyo polandira lamulo la kuthamanga ndi kutuluka kuchokera ku makina opangira jekeseni, imapanga mawerengedwe a PID ndi kukakamiza kwenikweni ndi kuyankha mofulumira kuyendetsa galimoto ya servo ndi pampu ya hydraulic ndi nthawi yoyankha mofulumira komanso kubwereza kubwereza kolondola.
Kusintha kokhazikika
Zosankha Zosankha
Mawonekedwe a Hydraulic Energy System (Zinthu zisanu)
Kugwiritsa ntchito kwambiri mphamvu zamakina omangira jekeseni
Mukamagwiritsa ntchito ma hydrualic system, mphamvu yogwiritsira ntchito mphamvu ndi yoposa 75% ya dongosolo lonse la jakisoni. Kupanikizika kosiyana ndi kuyenda kumafunika panthawiyi, kuphatikizapo kutseka kwa nkhungu, jekeseni, kugwira ntchito ndi kutseguka kwa nkhungu. Pamene kuyendayenda ndi kupanikizika kumapitirira zoikidwiratu, mpumulo kapena valve yofanana idzasinthidwa, zomwe zimapangitsa kuti 40% -75% ikhale yogwiritsidwa ntchito kwambiri.
Ubwino Usanu Wapamwamba
Kagwiritsidwe:
Momwe mungasankhire Hybrid Energy System yoyenera
(1) Kusankha Mphamvu Zamagetsi
● Torque yofunika (Nm) T=q.∆p
2π·ηm
● Mphamvu zotulutsa (kw) P=2π·T·n = T · n =Q·∆p
60,000 9550 60·πη
q: cc/rev Kusamuka (cm3) n: Liwiro lozungulira∆p: Kusiyanitsa kovomerezeka (Mpa)
Q: Kuyenda kofunikira L / minηm: Kuthamanga kwamakina pampu ηt: Pampu kukwanira kwathunthu
(2) Njira yothetsera Kusokoneza kwa Signal
Pamene galimoto imayikidwa pa gulu lolamulira, chitetezo cha kusokoneza chizindikiro ndi:
● Mawaya a dera lalikulu ndi dera lowongolera ayenera kukhala osiyana.
● Kukhazikika koyenera ngati kuli kofunikira
● Gwiritsani ntchito chingwe chotchinga pagawo lowongolera
● Gwiritsani ntchito mawaya otchingira pa mawaya akuluakulu ozungulira
(3) Momwe Mungasankhire Yoyenera Hybrid Servo Drive ndi Motor
M'mapulogalamu enieni, kusankha kwa hybrid servo drive ndi motor wikl kumakhala kosiyana chifukwa chamitundu yosiyanasiyana yamafuta.
M'zitsanzo zotsatirazi kuthamanga kwa 64L / min ndi max. Kuthamanga kwa 17.5 Mpa kumagwiritsidwa ntchito.
● Kusamuka kwa Mapampu a Hydraulic:Pezani kusamuka kwa pampu ya hydraulic (cc/rev) kuchokera ku max. Kuyenda kwadongosolo (L/mphindi)
Chitsanzo: Tangoganizani kuti max. Kuthamanga kwa dongosolo ndi 64L / min. ndi max. liwiro la injini ndi 2000rpm. Kusamuka kwa pampu ya hydraulic kudzakhala 64/2000*1000=32cc/rev
● Max. Moto torque:kupeza max. torque kuchokera max. kuthamanga ndi kusamuka kwa pampu ya hydraulic
Chitsanzo: Tiyerekeze kuti max. Kuthamanga ndi 17.5 Mpa ndipo kusamutsidwa kwa hydraulic pump ndi 32cc/rev. Makokedwe adzakhala 17.5 * 32 * 1.3/ (2p) = 116Nm (chinthu ndi 1.3 kwa chipukuta misozi zotayika zonse dongosolo ndipo akhoza kusinthidwa 1.2 kuti 1.3 monga pakufunika)
● Ma torque ovotera ndi ovotera mphamvu yamagalimoto:Torque yofunikira kuti mugwire mwamphamvu pa max. kupanikizika kuyenera kukhala kowirikiza kawiri pa torque ya mota kapena kucheperapo ( gwiritsani ntchito zomwe zaperekedwa kuchokera pafakitale ngati chinthu chofunikira kwambiri). Chifukwa kutentha kwa injini komwe kumagwiritsidwa ntchito panthawiyi kumakhala kosavuta kuposa kutentha. Tangoganizani kuti timasankha torque iwiri yovotera, galimotoyo imakhala 9.1kW* yokhala ndi liwiro la 1500rpm pomwe ma torque ovotera ndi 58N-m.
*Motor Power Formula:P(W)=T(Nm)Xw (rpmX2π/ 60)
●Max. Magalimoto Apano:
Ngati mupeza coefficient kt (Torque/A)=3.31 mumayendedwe agalimoto, max. panopa ndi pafupifupi 115/3.31=35A pamene max. Torque ndi 116N-m.
● Sankhani Kuyendetsa Kumanja:Chonde sankhani kuyendetsa koyenera malinga ndi zomwe makasitomala amafuna. Tangoganizani kuti kuthekera kwa kuchuluka kwa magalimoto ndi 150% kwa masekondi 60 ndi 200% kwa masekondi atatu. Pamene mphamvu yogwira ili pa max. Kuthamanga kwa 17.5 Mpa ndi 32cc/rev hydraulic pump, injini yamakono yomwe imafunikira ndi 35A.
Zindikirani Ngati palibe mota yoyenera, chonde gwiritsani ntchito injini yamagetsi yotsatira.
Chonde funsani Delta ngati muli ndi mafunso okhudza hybrid servo drive kapena kuphatikiza ndi makina anu apano.
