A hydraulic systemamagwiritsa ntchito madzi opanikizika kuti apereke mphamvu ndikugwira ntchito zamakina. Imatembenuza mphamvu yamakina kukhala mphamvu yamadzimadzi, kenako ndikubwerera kumayendedwe. Mainjiniya amadalira mfundo monga Navier-Stokes equations ndi Darcy-Weisbach formula kuti akwaniritse bwino.kapangidwe ka hydraulic system, monga momwe zasonyezedwera mwatsatanetsataneChithunzi cha hydraulic system.
Zofunika Kwambiri
- Makina a Hydraulic amagwiritsa ntchito madzi oponderezedwa kuti achulukitse mphamvu ndikuchita ntchito zolemetsa ndikuwongolera bwino, kutengera Lamulo la Pascal.
- Zigawo zazikuluzikulu zikuphatikizapomapampu, ma reservoirs, ma valve, actuators, ndi madzimadzi, chilichonse chofunikira pakutumiza ndi kuwongolera mphamvu moyenera.
- Makina opangira ma hydraulic amayendetsa mafakitale ambiri popereka mphamvu zambiri, mphamvu zamagetsi, komanso kudalirika, koma amafunikira kukonza pafupipafupi kuti apewe kutayikira ndi kuipitsidwa.
Momwe Hydraulic System Imagwirira Ntchito
Mfundo Zoyambira za Hydraulic System (Lamulo la Pascal)
Dongosolo la hydraulic limagwira ntchito motengera Pascal's Law, mfundo yofunikira pamakina amadzimadzi. Lamulo la Pascal limanena kuti pamene kukakamiza kumagwiritsidwa ntchito pamadzi otsekeka, kupanikizika kumafalikira mofanana kumbali zonse mumadzimadziwo. Mfundo iyi imalola makina a hydraulic kuchulukitsa mphamvu ndikukweza zolemetsa ndikulowetsa pang'ono.
Mwachitsanzo, munthu akagwiritsa ntchito mphamvu pa pisitoni yaing’ono, mphamvu yochokera m’madziyo imadutsa mapaipi ndi mapaipi kupita ku pistoni yaikulu. Pistoni yokulirapo, yokhala ndi malo okulirapo, imatulutsa mphamvu yayikulu kwambiri. Ubale pakati pa zolowetsa ndi mphamvu zotulutsa zimatengera kuchuluka kwa madera a pistoni. Ngati pisitoni yolowetsayo ili ndi dera la 2 lalikulu masentimita ndipo pistoni yotulutsa ili ndi dera la masentimita 20, mphamvu yotulutsa idzakhala yochulukirapo kakhumi kuposa mphamvu yolowera, poganiza kuti kukakamiza komweko kumagwiritsidwa ntchito.
Lamulo la Pascal limathandizira ma hydraulic system kuti agwiritse ntchito mapaipi ndi zotengera zamitundu yosiyanasiyana osataya mphamvu, kuwapangitsa kukhala osinthika kwambiri pamakina osiyanasiyana.
Mfundo imeneyi imapanga maziko a zipangizo monga makina osindikizira a hydraulic, mabuleki agalimoto, ndi makina omanga. Kutha kufalitsa kupanikizika mofanana kumalola mainjiniya kupanga makina omwe amatha kukweza magalimoto, kugwiritsa ntchito zida zolemetsa, komanso kupereka kuwongolera koyenera pamafakitale.
Kuchita Pang'onopang'ono kwa Hydraulic System
Kugwira ntchito kwa ma hydraulic system kumaphatikizapo njira zingapo zofunika, iliyonse imathandizira kusamutsa bwino ndikuwongolera mphamvu. Zotsatirazi zikuwonetsa ndondomeko yodziwika bwino:
- Kulowetsa Mphamvu: Dongosolo limayamba ndi makina olowetsamo, monga mota yamagetsi kapena injini, yomwe imayendetsa apampu ya hydraulic.
- Fluid Pressurization: Pampu imakoka madzimadzi amadzimadzi kuchokera m'madzi ndikuupanikiza, ndikupanga kutuluka kwamadzimadzi mothamanga kwambiri.
- Kutumiza kwa Pressure: Madzi opanikizika amayenda kudzera pa mapaipi ndi mapaipi kupita kuzinthu zosiyanasiyana, monga ma valve ndi ma actuators.
- Kuwongolera ndi mayendedwe: Mavavu amawongolera komwe akupita, kuthamanga, ndi kuthamanga kwamadzimadzi, zomwe zimalola kuwongolera kusuntha kwa ma actuators.
- Kutulutsa Kwamakina: Ma actuators, monga masilindala kapenama hydraulic motors, tembenuzani mphamvu yamadzimadzi kuti ibwererenso kumayendedwe amakina, kuchita ntchito monga kukweza, kukankha, kapena kuzungulira.
- Kubwereranso Kuyenda: Akamaliza ntchito yake, madzimadzi amabwerera kumalo osungiramo madzi, okonzeka kubwezeretsedwanso ndi mpope.
Akatswiri nthawi zambiri amagwiritsa ntchito zida zowunikira, kuphatikiza zoyezera kuthamanga ndi ma multimeter adijito, kuyang'anira magawo amakina monga kupanikizika ndi mawonekedwe amagetsi. Ngati miyeso ikuwonetsa zolakwika, atha kuyang'ana zida zamkati kuti ziwonongeke kapena kuwonongeka. Njirayi imagwirizanitsa deta yochuluka ndi kuyang'anitsitsa kowonekera kuti zitsimikizidwe kuti zikugwira ntchito bwino.
Kafukufuku woyeserera awonetsa kuti makina a hydraulic amatha kupulumutsa mphamvu zambiri ndikuwongolera bwino pogwiritsa ntchito matekinoloje apamwamba. Mwachitsanzo, mabwalo ogwiritsira ntchito ma valve oyendetsa magetsi amatha kuchepetsa kugwiritsa ntchito mphamvu ndi 15% popanda katundu ndipo pafupifupi 10% pa katundu wapamwamba. Kuyeza kwa kutentha kumawonetsanso kuti machitidwe ogwira mtima amagwira ntchito pa kutentha kochepa, zomwe zimapangitsa kuti zikhale zokhazikika komanso zimachepetsa kuvala.
Miyezo yamakampani, monga ISO 4409:2007, imapereka malangizo oyesa ndikutsimikizira mphamvu zamapampu a hydraulic ndi ma mota. Miyezo iyi imawonetsetsa kuti opanga ndi mainjiniya atha kudalira deta yolondola, yobwerezabwereza posankha ndikusunga zida zamakina.
Zindikirani: Kumvetsetsa kagwiritsidwe ntchito pang'onopang'ono komanso mfundo zoyambira zama hydraulic system kumathandiza mainjiniya kupanga makina odalirika komanso ogwira ntchito pazantchito zosiyanasiyana.
Zigawo Zazikulu za Hydraulic System
Dongosolo la hydraulic limadalira zigawo zingapo zofunika, chilichonse chimagwira ntchito yake pakufalitsa ndi kuwongolera mphamvu. Kumvetsetsa magawowa kumathandiza mainjiniya kupanga makina abwino komanso odalirika.
Pampu ya Hydraulic
Thepampu ya hydraulicamasintha mphamvu zamakina kukhala hydraulic energy, ndikupanga kutuluka kwamadzimadzi opanikizidwa omwe amayendetsa dongosolo. Mitundu yamapampu wamba imaphatikizapo zida, vane, ndi mapampu axial piston. Mapampu amakono amapereka mphamvu zambiri, ndi zitsanzo zina zomwe zimakwaniritsa bwino 92% ndi kukakamiza kugwira ntchito mpaka 420 bar (6090 psi). Kuwongolera kwapamwamba pakompyuta kumalola kusintha kolondola kwakuyenda ndi kuthamanga, kupangitsa mapampu awa kukhala oyenera kugwiritsa ntchito mafakitale ndi mafoni.

Posungira
Malo osungiramo madzi amasungira madzimadzi amadzimadzi ndipo amalola kuti mpweya utuluke. Mapangidwe achikhalidwe amagwiritsa ntchito akasinja akulu, nthawi zambiri katatu kapena kasanu kuchuluka kwa pampu. Malo osungira amakono amagwiritsa ntchito mapangidwe ang'onoang'ono, nthawi zina amangofanana ndi pampu, zomwe zimachepetsa kulemera ndi malo apansi mpaka 80%. Zatsopanozi zimathandizira kuyendetsa bwino kwadongosolo komanso kutsika kwamafuta amafuta.
| Mtundu wa Metric | Traditional Reservoir | Malo Osungira Amakono |

| Kulemera | Zoyambira | Kufikira 80% zopepuka |
Mavavu
Mavavu amawongolera komwe akupita, kuthamanga, komanso kuthamanga kwamadzimadzi amadzimadzi. Mitundu imaphatikizapo ma valve othamanga, otsogolera, ndi othamanga. Mainjiniya amagwiritsa ntchito njira zochulukira monga kuyezetsa pang'ono sitiroko ndi kuyesa umboni wa in-situ kuti atsimikizire kudalirika kwa ma valve ndi chitetezo. Miyezo yamakono, monga ANSI/ISA-96.06.01-2022, imatanthawuza njira zogwirira ntchito za ma valve actuators, kuphatikizapo kufufuza ndi chitetezo.
Ma actuators (ma Cylinders ndi Motors)
Ma actuators amasintha mphamvu zama hydraulic kukhala zoyenda zamakina. Masilinda a Hydraulic amapanga kuyenda kwa mzere, pomwema hydraulic motorspangani mayendedwe ozungulira. Zidazi zimapereka mphamvu zambiri, ndi masilindala ena omwe amapanga mpaka 43,000 lbf. Ma electro-hydraulic actuators amatha kuchita bwino ndipo amatha kuchepetsa kugwiritsa ntchito mphamvu ndi 50% kudzera pakukonzanso mphamvu.
Madzi a Hydraulic
Madzi amadzimadzi amadzimadzi amatulutsa mphamvu, amapaka mafuta m'zigawo zina, ndikuchotsa kutentha. Kukhuthala kwa madzimadzi kumakhudza mphamvu, mafuta, ndi kupanga kutentha. Mainjiniya amasankha zamadzimadzi kutengera zomwe zimafunikira pamakina, kuchuluka kwa kutentha, ndi mtundu wa pampu. Zowonjezera monga anti-wear agents ndi rust inhibitors zimateteza mbali zamakina ndikuwonjezera moyo wamadzimadzi. Kusankhidwa koyenera kwamadzimadzi kumatsimikizira kugwira ntchito bwino komanso kudalirika kwa ma hydraulic system.
Mapulogalamu a Hydraulic System, Ubwino, ndi Kufananiza
Kugwiritsa Ntchito Wamba kwa Hydraulic System
Makina opanga ma hydraulic amayendetsa mafakitale osiyanasiyana. Zomangamanga, zaulimi, zakuthambo, magalimoto, ndi kagwiridwe ka zinthu zonse zimadalira makinawa ponyamula katundu ndi kuwongolera bwino. Mwachitsanzo, Pennar Industries ikukonzekera kupanga masilinda a hydraulic 150,000 pachaka paulimi ndi zomangamanga. Pulojekiti yothirira ya Polavaram imagwiritsa ntchito masilinda 96 a hydraulic kuti agwiritse ntchito zipata 48 zozungulira. Tebulo ili m'munsiyi ikuwonetsa kukula ndi kusiyanasiyana kwa mapulogalamu:
