M'mawu akuthupi, galimoto yamagetsi ndi chinthu chomwe chimasintha mphamvu kuti isunthe mtundu wina wa gawo la makina, kaya galimoto, chosindikizira.Ngati injiniyo ingasiya kuzungulira nthawi yomweyo, dziko lapansi silingaganizidwe.
Ma motors amagetsi amapezeka paliponse masiku ano, ndipo mainjiniya apanga mitundu yambiri yama injini kwazaka zambiri.
Ma motors ambiri ndi ma actuators, kutanthauza kuti pogwiritsa ntchito torque, amapanga kuyenda.Kwa nthawi yayitali, mphamvu yoyendetsa ma hydraulic ya ma hydraulic drive inali muyezo wanthawiyo.Komabe, mtundu uwu wamagalimoto ukuchulukirachulukira m'zaka za zana la 21 ndi kupita patsogolo kwa ma drive amagetsi, kuphatikiza kuti mphamvu yamagetsi yachuluka komanso yosavuta kuwongolera.Pa ziwirizi, kodi imodzi ili yabwino kuposa ina?Kapena izi zimadalira momwe zinthu zilili.
Chidule cha ma hydraulic systems
Ngati mudagwiritsapo ntchito jack pansi, kapena kuyendetsa galimoto yokhala ndi mabuleki amphamvu kapena chiwongolero champhamvu, mutha kudabwa kuti mutha kusuntha zinthu zambiri popanda kugwiritsa ntchito mphamvu zambiri.(Kumbali inayi, mwina munatanganidwa kwambiri ndi ntchito yosinthira tayala m’mbali mwa msewu kuti muganizire maganizo amenewa.)
Ntchito izi ndi zofananira zimatheka chifukwa chogwiritsa ntchito ma hydraulic system.Dongosolo la hydraulic silipanga mphamvu, koma m'malo mwake limatembenuza kuchokera ku gwero lakunja kukhala mawonekedwe ofunikira.
Kuphunzira kwa ma hydraulics kumaphatikizapo magawo awiri akulu.Ma hydraulics ndikugwiritsa ntchito madzi amadzimadzi kuti agwire ntchito mothamanga kwambiri komanso kupanikizika kochepa.Mphero “zachikale” zimagwiritsa ntchito mphamvu ya madzi popera mbewu.Mosiyana ndi izi, ma hydrostatics amagwiritsa ntchito kuthamanga kwambiri komanso kutsika kwamadzi kwamadzi kuti agwire ntchito.M'chinenero cha physics, kodi maziko a malondawa ndi ati?
Mphamvu, Ntchito ndi Malo
Maziko akuthupi ogwiritsira ntchito ma hydraulic motors ndi lingaliro la kuchulukitsa mphamvu.Mtengo wamtengo wapatali mu dongosolo ndi chinthu cha mphamvu ya ukonde yomwe imagwiritsidwa ntchito komanso mtunda wosunthidwa popanda chiwerengero Wnet = (Fnet) (d).Izi zikutanthawuza kuti pa ntchito yoperekedwa ku ntchito yakuthupi, mphamvu yofunikira kuti igwiritsidwe ntchito ikhoza kuchepetsedwa powonjezera mtunda wa ntchito ya mphamvu, monga kutembenuka kwa screw.
Mfundoyi imafalikira molunjika mpaka kuzithunzi ziwiri kuchokera ku chiyanjano p=F/A, pamene p=pressure mu N/m2, F=force mu Newtons, ndi A=dera mu m2.Mu hydraulic system pomwe kukakamiza p kumakhala kosalekeza, pali ma pistoni-silinda awiri okhala ndi madera ozungulira A1 ndi A2 omwe amatsogolera ku ubalewu.F1/A1 = F2/A2, kapena F1 = (A1/A2)F2.
Izi zikutanthauza kuti pisitoni yotulutsa A2 ikakhala yayikulu kuposa pisitoni ya A1, mphamvu yolowera idzakhala yaying'ono molingana ndi mphamvu yotulutsa.
Ma motors amagetsi amapezerapo mwayi chifukwa mphamvu ya maginito imapangitsa kuti pakhale mphamvu yosuntha kapena yapano.Chingwe chozungulira cha waya chimayikidwa pakati pa mitengo ya maginito amagetsi kuti mphamvu ya maginito ipange torque yomwe imapangitsa kuti koyiloyo izungulire mozungulira.Shaft iyi ingagwiritsidwe ntchito pazinthu zambiri, ndipo, mwachidule, galimotoyo imatembenuza mphamvu yamagetsi kukhala mphamvu yamakina.
Ma Hydraulics vs Electric Motors: Ubwino ndi Zoipa
Chifukwa chiyani mugwiritse ntchito mota ya hydraulic, injini yoyaka mkati kapena mota yamagetsi?Ubwino ndi kuipa kwa mtundu uliwonse wa mota ndizochulukirapo kotero kuti ndizofunikira kuziganizira pazochitika zilizonse zapadera.
Ubwino wa ma hydraulic motors
Ubwino waukulu wa ma hydraulic motors ndikuti amatha kugwiritsidwa ntchito kupanga mphamvu zapamwamba kwambiri.
Ma mota a Hydraulic amagwiritsa ntchito madzi osasunthika, omwe amalola kuwongolera molimba kwa injiniyo motero kumayenda bwino kwambiri.Pakati pa zida zolemetsa zam'manja, ndizothandiza kwambiri.
Kuipa kwa ma hydraulic motors
Ma hydraulic motors nawonso ndi okwera mtengo, mafuta onse akugwiritsidwa ntchito, kuchita izi moyipa kwambiri, zosefera zosiyanasiyana, mapampu ndi mafuta ziyenera kuyang'aniridwa, kusinthidwa, kutsukidwa, ndikusinthidwa.Kutaya kumatha kupangitsa kuti pakhale ngozi zachitetezo komanso zachilengedwe.
Ubwino wamagalimoto
Kutsegula kwa hydraulic motor sikuthamanga kwambiri, galimotoyo imathamanga kwambiri (mpaka 10m / s).Amakhala ndi liwiro lokhazikika komanso malo oyimitsa, mosiyana ndi ma hydraulic motors, omwe amatha kuyika bwino kwambiri.Masensa amagetsi amatha kupereka mayankho olondola pakuyenda ndi mphamvu yogwiritsira ntchito.
Kuipa kwa magalimoto
Ma motors awa ndi ovuta komanso ovuta kukhazikitsa poyerekeza ndi ma motors ena, ndipo amatha kulephera kwambiri poyerekeza ndi ma motors ena.Ambiri aiwo, choyipa chake ndikuti mumafunikira mphamvu zambiri, mumafunikira mota yayikulu komanso yolemera, mosiyana ndi ma hydraulic motors.
Chiyambi cha Pneumatic Drives
Pneumatic, electronic, or hydraulic actuators amatha kukhala ovuta muzochitika zina.Kusiyana pakati pa ma pneumatic ndi hydraulic actuators ndikuti ma hydraulic motors amagwiritsa ntchito madzi oyenda pomwe ma pneumatic actuators amagwiritsa ntchito mpweya, nthawi zambiri mpweya wamba.
Ma drive a pneumatic ndi opindulitsa pomwe mpweya uli wochuluka, kotero kuti kompresa ya gasi ndiyofunika kaye.Kumbali inayi, ma motors awa ndi operewera kwambiri chifukwa kutentha kwa kutentha kumakhala kwakukulu kwambiri poyerekeza ndi mitundu ina ya injini.
