Funso loti pampu ya hydraulic imatha kupanga kukakamiza ndikofunikira kuti timvetsetse ntchito yayikulu ya hydraulic system.M'malo mwake, mapampu a hydraulic amatenga gawo lalikulu pakutembenuza mphamvu yamakina kukhala mphamvu ya hydraulic, potero imapangitsa kupanikizika mkati mwamadzimadzi.Zidazi zidapangidwa kuti ziziyamwa madzimadzi amadzimadzi ndikugwiritsa ntchito mphamvu kuti zidutse mudongosolo, ndikupanga kukakamiza komwe kumapangitsa makina ndi zida zosiyanasiyana.Kaya mukugwiritsa ntchito pampu ya pistoni yobwerezabwereza kapena pampu ya giya yomwe imadalira magiya ozungulira, mapampu a hydraulic amapangidwa kuti apange mphamvu yofunikira kuti ma hydraulic system agwire bwino ntchito.
1. Mfundo yogwiritsira ntchito pampu ya hydraulic
2. Mtundu wa pampu ya hydraulic yomwe imapanga kuthamanga
3. Zinthu zomwe zimakhudza kupangika kwamphamvu m'ma hydraulic systems
1. Mfundo yogwiritsira ntchito pampu ya hydraulic
Pampu ya hydraulic ndi gawo lofunikira mu hydraulic system, ntchito yake yayikulu ndikupanga kukakamiza kuyendetsa madzi kudzera mu dongosolo.Kusinthasintha kwawo kumawalola kuti azitha kugwiritsa ntchito makina ndi zida zambiri, akugwira ntchito yofunika kwambiri m'mafakitale monga kupanga, zomangamanga ndi zoyendera.Apa tikuwunika mapampu awiri odziwika bwino a hydraulic omwe amapambana pakupanga mphamvu:
1. Pampu ya piston:
Mapampu a pistoni amadziwika kwambiri chifukwa chogwira ntchito bwino pakutulutsa kuthamanga kwambiri pamakina a hydraulic.Amagwira ntchito pa mfundo yobwezera, pomwe pisitoni imayenda mmbuyo ndi mtsogolo mkati mwa silinda.Pistoni ikatuluka, chotsekera chimapangidwa chomwe chimakokera mafuta a hydraulic mu silinda.Kenako, pisitoniyo ikamakulirakulira, imakanikizira madziwo, kuwakakamiza kudzera pa mpope ndi kulowa mu hydraulic system.
Chimodzi mwazabwino zazikulu zamapampu a pistoni ndikutha kutulutsa mphamvu zokwanira, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira mphamvu zambiri, monga makina olemera a mafakitale ndi makina osindikizira a hydraulic.Kuphatikiza apo, mapampu a pistoni osinthika amatha kusintha mayendedwe ake kuti azitha kuyendetsa bwino milingo yamakasitomala malinga ndi zofunikira za pulogalamuyo.
2. Pampu yamagetsi:
Mapampu a giya ndi mtundu wina wotchuka wa pampu ya hydraulic yomwe imadziwika ndi kuphweka komanso kudalirika.Amakhala ndi zida ziwiri za meshing - zida zoyendetsera ndi zida zoyendetsedwa - zoyikidwa mkati mwa mpope.Magiya akamazungulira, amapanga zipinda zomwe zimakoka madzimadzi a hydraulic polowera pompo.Kuzungulirako kumakakamiza madzimadzi kulowa munjira, ndikupanga mphamvu yofunikira kuti mugwiritse ntchito ma hydraulic system.
Ngakhale mapampu amagetsi sangakwaniritse milingo yothamanga kwambiri ngati mapampu a pistoni, amapambana pamapulogalamu omwe amafunikira kuyenda kosalekeza komanso kokhazikika kwamadzimadzi.Mapangidwe ake ophatikizika, otsika mtengo komanso osamalidwa pang'ono amapangitsa kuti ikhale yoyenera kuzigwiritsa ntchito m'mafakitale osiyanasiyana, kuphatikiza zida zogwirira ntchito, makina owongolera ndi ma hydraulic power unit.
Kusankhidwa kwa pampu ya pistoni ndi pampu ya giya zimatengera zofunikira za hydraulic system.Mapampu a pistoni amayamikiridwa pamapulogalamu omwe amafunikira kuthamanga kwambiri komanso kuyenda kosinthika, pomwe mapampu amagetsi amayamikiridwa chifukwa cha kuphweka kwawo, kudalirika komanso kutsika mtengo pakugwiritsa ntchito komwe kumayenda mosalekeza komanso kofanana ndikofunikira.Kupita patsogolo kosalekeza kwaukadaulo wa pampu ya hydraulic kukupitiliza kupititsa patsogolo magwiridwe antchito azinthu zofunikazi, kuyendetsa bwino komanso kupanga zatsopano m'mafakitale osiyanasiyana.
2. Mtundu wa pampu ya hydraulic yomwe imapanga kuthamanga
Pampu ya hydraulic ndi chida chosinthira mphamvu chomwe chimasintha mphamvu yamakina kukhala mphamvu yamadzimadzi.Mfundo yake yogwiritsira ntchito ndikugwiritsa ntchito kusintha kwa voliyumu yotsekedwa kunyamula madzi, ndikudalira mfundo ya kusintha kwa voliyumu kuti mukwaniritse ntchito.Mapampu a Hydraulic amagwira ntchito potengera kusintha kwa voliyumu yosindikizira, chifukwa chake amatchedwanso mapampu amtundu wa hydraulic.
Mapampu a Hydraulic amagawidwa kukhala mtundu wa zida, mtundu wa vane, mtundu wa plunger ndi mitundu ina malinga ndi kapangidwe kawo.Aliyense ali ndi makhalidwe ake, koma amagwira ntchito pa mfundo yomweyo.Kutuluka kwa pampu ya hydraulic kumatha kusinthidwa ngati pakufunika kuti akwaniritse zofunikira zamitundu yosiyanasiyana yogwirira ntchito.
Pamene pampu ya hydraulic ikugwira ntchito, imazungulira pansi pa kuyendetsa kwa prime mover, kuchititsa kuti voliyumu yogwira ntchito isinthe mosalekeza, motero kupanga njira ya kuyamwa mafuta ndi kutulutsa mafuta.Kuthamanga kwa pampu ya hydraulic kumadalira kusintha kwa voliyumu ya chipinda chogwirira ntchito ndi chiwerengero cha zosintha pa nthawi ya unit, ndipo ziribe kanthu kochita ndi kuthamanga kwa ntchito ndi mikhalidwe ya mapaipi akuyamwa ndi kutulutsa.
3. Zinthu zomwe zimakhudza kupangika kwamphamvu m'ma hydraulic systems
Mbadwo wa kukakamizidwa mu ma hydraulic systems umakhudzidwa ndi zinthu zambiri.Nazi zina mwazifukwa zazikulu:
**Kukula kwa katundu: Kuchulukitsitsa kwa hydraulic system, kumapangitsanso kuthamanga komwe kumayenera kupangidwa.Katunduyo akhoza kukhala kulemera kwa chigawo cha makina, kukangana, kapena kukana kwina.
**Viscosity yamafuta: Kukhuthala kwamafuta kumakhudza kuthamanga kwake komanso mawonekedwe ake pamapaipi.Mafuta a viscosity apamwamba amachepetsa kuthamanga kwa magazi ndikuwonjezera kuthamanga kwa magazi, pamene mafuta otsika a viscosity adzafulumizitsa kuthamanga kwa magazi ndi kuchepetsa kuthamanga kwa magazi.
**Utali wa Chitoliro ndi Diameter: Kutalika ndi kukula kwa chitoliro kumakhudza mtunda ndi kutuluka kwa mafuta mu dongosolo.Mapaipi aatali ndi mainchesi ang'onoang'ono amawonjezera kutayika kwamphamvu, potero amachepetsa kuthamanga kwadongosolo.
**Mavavu ndi zipangizo: Mavavu ndi zipangizo zina (monga zigongono, zolumikizira, ndi zina zotero) zimatha kuletsa kutuluka kwa mafuta, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri.Choncho, posankha ndi kugwiritsa ntchito zigawozi, chidwi chiyenera kuperekedwa ku zotsatira zake pa ntchito ya dongosolo.
** Kutayikira: Kutayikira kulikonse mudongosolo kumachepetsa kuthamanga komwe kulipo chifukwa kutayikira kumayambitsa kutayika kwamafuta ndikuchepetsa kupanikizika mudongosolo.Chifukwa chake, ndikofunikira kuyang'ana pafupipafupi ndikusamalira dongosolo lanu kuti mupewe kutayikira.
** Kusintha kwa kutentha: Kusintha kwa kutentha kumatha kukhudza kukhuthala ndi mawonekedwe amafuta.Kutentha kwakukulu kumawonjezera kukhuthala kwa mafuta, zomwe zimawonjezera kutayika kwamphamvu;pamene kutentha kutsika kumachepetsa mafuta, zomwe zimachepetsa kuthamanga kwa magazi.Choncho, zotsatira za kutentha ziyenera kuganiziridwa popanga ndi kugwiritsa ntchito ma hydraulic systems.
**Magwiridwe a Pampu: Pampu ya hydraulic ndi gawo lofunikira mu dongosolo lomwe limapanga kupanikizika.Kuchita kwa mpope (monga kusamuka, kuthamanga kwa ntchito, etc.) kumakhudza mwachindunji mphamvu yotulutsa mphamvu ya dongosolo.Kusankha pampu yoyenera pazosowa zamakina anu ndikofunikira kuti muwonetsetse kuti dongosolo likuyenda bwino.
** Ma Accumulators ndi Pressure Control Valves: Ma Accumulators ndi ma valve owongolera kuthamanga atha kugwiritsidwa ntchito kuwongolera kuchuluka kwa kuthamanga mu dongosolo.Mwa kusintha zigawozi, kulamulira kogwira mtima ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kakhoza kukwaniritsidwa.
Mbadwo wa kukakamizidwa mu ma hydraulic systems umakhudzidwa ndi zinthu zambiri.Pofuna kuwonetsetsa kuti dongosololi likugwira ntchito moyenera komanso moyenera, opanga ndi ogwira ntchito ayenera kuganizira izi ndikuchitapo kanthu kuti akwaniritse bwino komanso kasamalidwe.
Yankho lomveka bwino la funso lomwe linafunsidwa poyamba ndi inde - pampu ya hydraulic ndiyedi chida chachikulu chopangira mphamvu mu hydraulic system.Udindo wawo pakusintha mphamvu zamakina kukhala mphamvu zama hydraulic ndizofunikira m'mafakitale ambiri, kuyambira pakupanga ndi zomangamanga kupita kumlengalenga ndi magalimoto.Kupita patsogolo kosalekeza kwaukadaulo wa pampu ya hydraulic kukupitilizabe kukonzanso ndikuwongolera kukhathamiritsa, zomwe zimapangitsa kuti pakhale njira zoyendetsera bwino komanso zokhazikika zama hydraulic.Pamene makampani akukula, mapampu a hydraulic amakhalabe osagwedezeka pakufunika kwawo popereka mphamvu zofunikira pa ntchito zosawerengeka, kutsindika udindo wawo monga gawo lofunikira pamakina amasiku ano.
