II-Kodi pulasitiki makina jekeseni akamaumba ntchito?
Mfundo ntchito ya makina jekeseni akamaumba ndi ofanana ndi syringe jakisoni. Imeneyi ndi njira yaukadaulo yobaya pulasitiki wosungunuka (kutanthauza kutuluka kwamphamvu) mkabowo kotsekedwa kudzera pachikopa (kapena plunger) ndikupeza chinthucho mutachiritsa.
Kuumba jekeseni ndimachitidwe ozungulira, kuzungulira kulikonse kumaphatikizapo:
Kudyetsa kochulukirapo - kusungunuka kwa pulasitiki - jekeseni wamagetsi - kuzirala - kutsegula nkhungu ndi kutenga mbali. Chotsani ziwalo za pulasitiki ndikutseka nkhungu mozungulira.
Jekeseni akamaumba makina ntchito zinthu: jekeseni akamaumba makina ntchito zinthu monga kulamulira kiyibodi ntchito, magetsi dongosolo kulamulira ntchito ndi dongosolo hayidiroliki ntchito mbali zitatu. Kusankhidwa kwa njira yopangira jakisoni, kudyetsa zochita, kupanikizika kwa jakisoni, liwiro la jakisoni, mtundu wa ejection, kuwunika kutentha kwa gawo lililonse la mbiya, kupanikizika kwa jakisoni ndi kusintha kwakanthawi kumbuyo kunachitika motsatana.
Makina akamaumba a makina opangira jekeseni ndi awa: choyamba, pulasitiki wonunkhira kapena ufa amawonjezeredwa mu mbiya, ndipo pulasitiki amasungunuka ndikusinthasintha kwa kagwere ndi kutentha kwa khoma lakunja la mbiya. Kenako makina amapanga nkhungu ndi mpando wa jekeseni kupita chitsogolo, kuti nozzle ili pafupi ndi chipata cha nkhunguyo, kenako mafuta opanikizika amathiridwa mu silinda ya jekeseni kuti apange wononga. Ndodoyo imakankhidwira kutsogolo kuti kusungunuka kulowetsedwa mufa kotsekedwa ndikutentha kocheperako kuthamanga kwambiri komanso kuthamanga kwambiri. Patapita nthawi ina ndi kuthamanga atagwira (amatchedwanso akugwira kuthamanga) ndi kuzirala, ndi Sungunulani ndi olimba ndi kuumbidwa, ndi mankhwala akhoza kuchotsedwa (cholinga cha akugwira kuthamanga ndi kuteteza Reflux wa Sungunulani mu M'mimbamo Ndipo zitsimikizirani kuti malonda ali ndi makulidwe ena komanso olekerera. Zomwe zimafunikira jekeseni ndi pulasitiki, jekeseni ndi kuwumba. Pulasitiki ndi chiyembekezo chokwaniritsira ndikuwonetsetsa kuti zinthu zikuumba bwanji, ndipo Pofuna kuthana ndi zofunikira pakuumba, jekeseni iyenera kutsimikizira kuthamanga ndi kuthamanga kwakanthawi.Pa nthawi yomweyo, chifukwa kuthamanga kwa jekeseni kumakhala kokwera kwambiri, kofanana ndi kuthamanga kwakukulu m'mimbamo (kuthamanga kwapakati pamimbamo kumakhala pakati pa 20 ndi 45 MPA), chifukwa chake payenera kukhala mphamvu yokwanira yolumikizira.Titha kuwona kuti chida cha jekeseni ndi chida chomenyera ndizofunikira kwambiri pamakina opangira jekeseni.
Kuwunika kwa zinthu zapulasitiki makamaka kumaphatikizapo zinthu zitatu: yoyamba ndi mawonekedwe a mawonekedwe, kuphatikiza umphumphu, utoto, kunyezimira, ndi zina; chachiwiri ndikulondola pakati pa kukula ndi malo ofanana; chachitatu ndi zinthu zakuthupi, zamagetsi komanso zamagetsi zogwirizana ndi ntchito. Zofunikira za khalidweli ndizosiyana malinga ndi zochitika zosiyanasiyana za malonda. Zolakwitsa zazogulitsazo zimangokhala pakupanga, kulondola komanso mtundu wa nkhungu. M'malo mwake, akatswiri m'makina opangira pulasitiki nthawi zambiri amakhala ndi zovuta zogwiritsa ntchito njira zaukadaulo zothetsera mavuto omwe amabwera chifukwa chakupunduka kwa nkhungu ndipo samakhudza kwenikweni.
Kusintha kwa njira ndi njira yofunikira yosinthira komanso kutulutsa kwa zinthu. Chifukwa jekeseni wokha ndi waufupi kwambiri,
ngati zochitikazo sizikuyang'aniridwa bwino, zonyansazo ziziyenda mosalekeza. Mukasintha ndondomekoyi, ndibwino kuti musinthe mkhalidwe umodzi kamodzi ndikuziwona kangapo. Ngati kupanikizika, kutentha ndi nthawi zimagwirizana ndikusinthidwa, ndikosavuta kuyambitsa chisokonezo ndi kusamvana. Pali njira zambiri komanso njira zosinthira ndondomekoyi. Mwachitsanzo, pali njira zoposa khumi zothetsera vuto la jekeseni wosakwanira wa mankhwala. Kungosankha njira imodzi kapena ziwiri zothetsera vuto la vutoli ndi pomwe tingathetse vutolo. Kuphatikiza apo, tiyeneranso kulabadira ubale wothandizirana ndi yankho. Mwachitsanzo: mankhwalawa amakhala ndi vuto, nthawi zina amatulutsa kutentha, nthawi zina kuti achepetse kutentha kwa zinthu; nthawi zina kuwonjezera kuchuluka kwa zinthu, nthawi zina kuti muchepetse zakuthupi. Zindikirani kuthekera kothetsa vutoli ndi njira zosinthira.
