Dongosolo la servo ndi njira yosungira mphamvu komanso yothandiza yowongolera ma hydraulic yomwe imagwiritsa ntchito mota ya servo kuyendetsa pampu yayikulu yamafuta otumizira, kuchepetsa dera lowongolera ma valve, ndikuwongolera njira yotsatirira ya hydraulic system. Ndi yoyenera kupondaponda, kupangira ma die, kufinya ma press, kuponya ma die, kuumba ma injection, kuwongola, ndi njira zina.
Poyerekeza ndi makina osindikizira wamba a hydraulic,makina osindikizira a servo hydraulicali ndi ubwino wosunga mphamvu, phokoso lochepa, kugwira ntchito bwino kwambiri, kusinthasintha bwino, komanso kugwira ntchito bwino kwambiri. Dongosolo la servo drive likhoza kulowa m'malo mwa machitidwe ambiri a hydraulic omwe alipo kale.
1. Kusunga mphamvu:
(1) Pamene chotsetsereka chikugwa mofulumira kapena chosasuntha pamalo okwera, mota ya servo siizungulira, kotero palibe mphamvu yamagetsi yomwe imagwiritsidwa ntchito. Mota ya makina osindikizira achikhalidwe a hydraulic imazungulirabe pa liwiro lovomerezeka. Komabe, imagwiritsa ntchito 20% mpaka 30% ya mphamvu yovomerezeka (kuphatikiza mphamvu yomwe imagwiritsidwa ntchito ndi chingwe cha mota, kugwedezeka kwa pampu, kukana kwa njira ya hydraulic, kutsika kwa kuthamanga kwa valavu, kulumikizana kwa makina, ndi zina zotero).
(2) Pa nthawi yogwira mphamvu, liwiro la servo motor ya servo hydraulic press limawonjezera kutayikira kwa pampu ndi makina. Liwiro nthawi zambiri limakhala pakati pa 10rpm ndi 150rpm. Mphamvu yomwe imagwiritsidwa ntchito ndi 1% mpaka 10% yokha ya mphamvu yovotera. Kutengera njira yogwirira mphamvu, mphamvu yeniyeni yomwe imagwiritsidwa ntchito pogwira mphamvu ya hydraulic press panthawi yogwira mphamvu ndi 30% mpaka 100% ya mphamvu yovotera.
(3) Poyerekeza ndi ma mota wamba, mphamvu ya ma mota a servo ndi yokwera ndi pafupifupi 1% mpaka 3%. Izi zimatsimikizira kuti makina osindikizira a hydraulic oyendetsedwa ndi servo ndi osunga mphamvu zambiri.
2. Phokoso lochepa:
Pampu yamafuta ya makina osindikizira a hydraulic oyendetsedwa ndi servo nthawi zambiri imagwiritsa ntchito pampu ya giya yamkati, pomwe makina osindikizira achikhalidwe a hydraulic nthawi zambiri amagwiritsa ntchito pampu ya pistoni ya axial. Pansi pa kayendedwe ndi kupanikizika komweko, phokoso la pampu ya giya yamkati ndi lotsika ndi 5dB ~ 10dB kuposa la pampu ya pistoni ya axial.
Pamene makina osindikizira a servo hydraulic akukanikiza ndi kubwerera, injiniyo imayenda pa liwiro lovomerezeka, ndipo phokoso lake lotulutsa mpweya limakhala lotsika ndi 5dB ~ 10dB kuposa la makina osindikizira achikhalidwe a hydraulic. Pamene makina osindikizira akutsika mofulumira komanso osasuntha, liwiro la injini ya servo ndi 0, kotero makina osindikizira a hydraulic oyendetsedwa ndi servo alibe kutulutsa mpweya.
Pa nthawi yogwira mphamvu, chifukwa cha liwiro lochepa la injini, phokoso la makina osindikizira a hydraulic oyendetsedwa ndi servo nthawi zambiri limakhala lochepera 70dB, pomwe phokoso la makina osindikizira achikhalidwe a hydraulic ndi 83 dB ~ 90 dB. Pambuyo poyesa ndi kuwerengera, pansi pa mikhalidwe yabwinobwino yogwirira ntchito, phokoso lopangidwa ndi makina osindikizira 10 a servo hydraulic limakhala lotsika kuposa lomwe limapangidwa ndi makina osindikizira wamba a hydraulic omwe ali ndi mawonekedwe omwewo.
3. Kutentha kochepa, kuchepetsa mtengo woziziritsira, komanso kuchepetsa mtengo wamafuta a hydraulic:
Dongosolo la hydraulic la makina osindikizira a hydraulic oyendetsedwa ndi servo silikhala ndi kutentha kochulukira. Pamene chotsitsacho chili chosasunthika, palibe kutentha komwe kumatuluka komanso kosagwirizana ndi hydraulic. Kutentha komwe kumapangidwa ndi makina ake osindikizira nthawi zambiri kumakhala 10% mpaka 30% ya komwe kumapangidwa ndi makina osindikizira achikhalidwe a hydraulic. Chifukwa cha kutentha kochepa komwe kumapangidwa ndi makinawa, makina ambiri osindikizira a servo hydraulic safuna makina oziziritsira mafuta a hydraulic, ndipo ena omwe amapangidwa ndi kutentha kwambiri amatha kukhala ndi makina oziziritsira otsika mphamvu.
Popeza pampuyo ili pa liwiro lopanda zero ndipo nthawi zambiri imapanga kutentha pang'ono, thanki yamafuta ya makina osindikizira a hydraulic olamulidwa ndi servo ikhoza kukhala yaying'ono kuposa ya makina osindikizira achikhalidwe a hydraulic, ndipo nthawi yosinthira mafuta imathanso kukulitsidwa. Chifukwa chake, mafuta a hydraulic omwe amagwiritsidwa ntchito ndi makina osindikizira a servo hydraulic nthawi zambiri amakhala pafupifupi 50% yokha ya makina osindikizira achikhalidwe a hydraulic.
4. Kuchuluka kwa zochita zokha, kusinthasintha bwino, komanso kulondola kwambiri:
Kupanikizika, liwiro, ndi malo a makina osindikizira a servo hydraulic ndi makina olamulira a digito otsekedwa bwino. Mphamvu yake yodziyimira payokha komanso kulondola kwake. Kuphatikiza apo, kuthamanga kwake ndi liwiro lake zimatha kukonzedwa ndikuwongoleredwa kuti zikwaniritse zosowa zosiyanasiyana za njira.
5. Kugwiritsa ntchito bwino kwambiri:
Kudzera mu kufulumizitsa ndi kuchepetsa mphamvu moyenera komanso kukonza mphamvu, liwiro la makina osindikizira a hydraulic olamulidwa ndi servo likhoza kusinthidwa kwambiri, ndipo nthawi yogwirira ntchito ndi yokwera kangapo kuposa makina osindikizira achikhalidwe a hydraulic. Imatha kufika 10/mphindi ~ 15/mphindi.
6. Kukonza kosavuta:
Chifukwa cha kuchotsedwa kwa valavu ya hydraulic ya servo yofanana, dera lowongolera liwiro, ndi dera lolamulira kuthamanga mu dongosolo la hydraulic, dongosolo la hydraulic limasavuta kwambiri. Zofunikira za ukhondo wa mafuta a hydraulic ndizochepa kwambiri kuposa za dongosolo la hydraulic proportional servo, zomwe zimachepetsa mphamvu ya kuipitsa mafuta a hydraulic pa dongosololi.
Zhengxindi katswirifakitale yosindikizira ya hydraulicku China ndipo imapereka makina osindikizira apamwamba kwambiri a hydraulic okhala ndi makina a servo hydraulic. Ngati muli ndi zosowa zilizonse, titumizireni uthenga!
