Ukuze uqonde ukuthi futha plunger, kufanele kuqala ukunquma ukuthi iyiphi isigaba ke singasho sithi. Kaningi kunesidingo ekhaya e ukuxuba izingxenye eziningi yesixazululo kunoma iyiphi isilinganiso esithile. Ngokuvamile asetshenziselwe le nhloso futha nokushintsha kokudla nokufakwa. Kuyinto idivayisi wokubacindezela okuvumela uhlanganise futhi basabalalise izinto eziwuketshezi. On imininingwane yomsebenzi wabo, amaphampu ezinjalo zihlukaniswe ayimihle nevolumu. umehluko wabo ngethangi ekhethekile lapho uketshezi ayanikezelwa yokuhlanganisa.
Kukhona lolu hlobo like futha plunger elingelakwaJuda esigabeni by volume. Emsebenzini walo imininingwane kanye nesakhiwo thuluzi afana piston. Umehluko omkhulu itholakala izici we plunger, ukuthi kuyinto piston ekhethekile. Kuyinto induku metallic ezihambayo ekamelweni tekusebenta metering futha reciprocates, lapho izindonga ke akasabeli. I plunger liyisici esiyisisekelo for futha plunger. Kule ndaba, kuyakushiswa ethulwa eziningi nezimfuneko ezithile: kumele kube eziqinile, ukuvuza-ubufakazi futhi iqine, ukuhlinzeka izinga okusezingeni eliphezulu kanye nokusebenza onokwethenjelwa futha. Izindleko zedivayisi kuxhomeke kulokho izinto senziwa.
Piston futha has imininingwane ethile wokusebenza: lapho plunger ihamba ngakwesokudla, ingcindezi egumbini ukusebenza is kakhulu ziyancipha futhi ingcindezi kule line ukuncela stably sisalokhu siphakeme. Lapho kwakhiwa umehluko ingcindezi, valve ukuncela iqala ukusebenza, lapho ketshezi bese ihamba nayo egumbini ukusebenza kwe-futha. Lapho uhamba plunger kwesobunxele, ushintsho okuphambene ingcindezi kwenzeka, ngenxa okuyinto valve osenyameni ivuleka, okuyinto displaces uketshezi esuka egumbini ukusebenza.
Plunger futha nge ushintsho ingcindezi kudala ezinye okusizwa ukushaya. Lokhu kungaba kabi nomthelela ekusebenzeni idivayisi, ngakho le nkinga kumele ixazululwe. Ungasebenzisa pistons eziningana axhunyiwe kushaft, ngesikhathi esifanayo babe ukuhambisa ngemijikelezo, kodwa umjikelezo ngamunye kumele lingafani omunye engela kanye nokunyakaza isigaba. Enye ukudala amathuba nemibandela operation umehluko futha lapho ukudonsa wenziwa phakathi umphini ukunyakaza ukuphendukela kunoma iluphi uhlangothi.
amanzi Piston amaphampu bahlinza isimiso esifanayo njengoba ezivamile. Umthamo uketshezi akhishwa lapha incike ekutheni ngaphakathi is Umfutho, okusho ukuthi, ephakeme ukubaluleka, indaba ngaphezulu sihamba. Design izici amadivayisi uvumele kuwahlukanise ngezigaba eziningana: multiplunger olulodwa futhi; ibhantshi Ukushisa, ngaphandle-ke, lo mbhalo uphawu; nge ibhukwana noma othomathikhi; enezingqimba noma mpo; single- ne-multi-cylinder. Plunger ingcindezi high amaphampu labo abazokwazi ezisebenza nge izinhlobo ezahlukene ketshezi, ngokuqondene lapho kwenziwa ngezinto ezahlukene, kuye ngokuthi imvelo ukusebenza.
