Incike ekunyakazeni okuphindaphindayo kwe-plunger kusilinda ukuze iguqule umthamo wegumbi lokusebenza elivaliwe ukuze libone ukumuncwa kukawoyela nokucindezela kukawoyela. Iphampu ye-plunger inezinzuzo zokucindezela okuphezulu okulinganiselwe, isakhiwo esihlangene, ukusebenza kahle okuphezulu kanye nokulungiswa kokugeleza okulula. Amaphampu e-piston asetshenziswa kakhulu ekucindezelweni okuphezulu, ukugeleza okukhulu kanye nezikhathi lapho ukugeleza kudinga ukulungiswa khona, njengokucindezela kwe-hydraulic, imishini yobunjiniyela nemikhumbi.
Amaphampu e-piston ngokuvamile ahlukaniswa abe amaphampu e-plunger eyodwa, amaphampu e-plunger avundlile, amaphampu e-axial plunger kanye namaphampu e-radial plunger.
iphampu ye-plunger eyodwa
Izingxenye zesakhiwo ikakhulukazi zifaka isondo eli-eccentric, i-plunger, isiphethu, umzimba we-cylinder, nama-valve amabili endlela eyodwa. Umthamo ovaliwe uyakhiwa phakathi kwe-plunger kanye nebhore yesilinda. Lapho isondo eliyi-eccentric lizungeza kanye, i-plunger ibuyela phezulu naphansi kanye, yehlela phansi ukuze imunce uwoyela, futhi ikhuphukele phezulu ukuze ikhiphe uwoyela. Ivolumu kawoyela ekhishwa ngokuphenduka ngakunye kwepompo kubizwa ngokuthi i-displacement, futhi ukususwa kuhlobene kuphela nemingcele yesakhiwo sepompo.
Iphampu ye-plunger evundlile
Iphampu ye-plunger evundlile ifakwe eduze nama-plunger ambalwa (ngokuvamile angu-3 noma angu-6), futhi i-crankshaft isetshenziselwa ukusunduza i-plunger ngokuqondile kusilayida senduku yokuxhuma noma i-eccentric shaft ukwenza ukunyakaza okuhambisanayo, ukuze kubonakale ukuncela nokudonsa. ukukhishwa kwe-liquid. iphampu ye-hydraulic. Futhi wonke asebenzisa amadivaysi okusabalalisa ukugeleza kohlobo lwe-valve, futhi iningi lawo amaphampu omthamo. Amaphampu e-emulsion kumasistimu okusekela amanzi asebenza ezimayini yamalahle ngokuvamile amaphampu e-plunger avundlile. Ipompo ye-emulsion isetshenziswa ebusweni bezimayini zamalahle ukuze inikeze i-emulsion yokusekelwa kwe-hydraulic. Umgomo wokusebenza uncike ekujikelezeni kwe-crankshaft ukushayela i-piston ukuze ibuyele ukuze ibone ukudonsa nokukhishwa koketshezi.
Iphampu ye-axial piston
Iphampu ye-axial piston iyipompo ye-piston lapho isiqondiso esiphindaphindayo se-piston noma i-plunger sihambisana ne-eksisi emaphakathi yesilinda. Iphampu ye-axial piston isebenza ngokusebenzisa ukuguqulwa kwevolumu okubangelwa ukunyakaza okuphindaphindayo kwe-plunger ehambisana ne-transmission shaft emgodini we-plunger. Njengoba kokubili i-plunger kanye nembobo ye-plunger kuyizingxenye eziyindilinga, ukulingana okuphezulu okunembayo kungafinyelelwa, ngakho ukusebenza kahle kwevolumu kuphezulu.
Iphampu ye-plunger shaft shaft eqondile
Amaphampu e-Straight shaft swash plate plunger ahlukaniswe abe uhlobo lokuphakelwa kukawoyela ocindezelwe kanye nohlobo lukawoyela oziqalayo. Amaphampu kawoyela ocindezelwe kakhulu asebenzisa ithangi likaphethiloli elinomfutho womoya, kanye nethangi likawoyela we-hydraulic elincike kumfutho womoya ukuhlinzeka uwoyela. Ngemuva kokuqala umshini ngaso sonke isikhathi, kufanele ulinde ithangi likawoyela we-hydraulic ukuthi lifinyelele umfutho womoya osebenzayo ngaphambi kokusebenzisa umshini. Uma umshini uqalwa lapho umfutho womoya ethangini likawoyela we-hydraulic unganele, isicathulo esishelelayo kupompo ye-hydraulic sizokhishwa, okuzobangela ukuguga okungavamile kwepuleti lokubuyisela kanye nepuleti lokucindezela emzimbeni wepompo.
iphampu ye-radial piston
Amaphampu e-radial piston angahlukaniswa ngezigaba ezimbili: ukusatshalaliswa kwe-valve kanye nokusabalalisa kwe-axial. Amaphampu e-radial piston okusabalalisa ama-valve anezinga eliphezulu lokuhluleka kanye namaphampu e-piston asebenza kahle kakhulu. Ngenxa yezici zesakhiwo samaphampu e-radial, amaphampu e-axial distribution radial piston anokumelana nomthelela ongcono, impilo ende kanye nokunemba okuphezulu kokulawula kunamaphampu e-axial piston. . I-stroke eguquguqukayo yepompo ye-stroke eguquguqukayo emfushane ifinyelelwa ngokushintsha ukucaca kwe-stator ngaphansi kwesenzo se-plunger eguquguqukayo kanye ne-limit plunger, futhi i-eccentricity ephezulu ingu-5-9mm (ngokokususwa), futhi ukushaywa okuguquguqukayo kukhulu kakhulu. kufushane. . Futhi indlela eguquguqukayo yenzelwe ukusebenza kwengcindezi ephezulu, elawulwa yi-valve yokulawula. Ngakho-ke, isivinini sokuphendula sepompo siyashesha. Idizayini yesakhiwo se-radial inqoba inkinga yokugqokwa kwe-eccentric yesicathulo esishelelayo sepompo ye-axial piston. Ithuthukisa kakhulu ukumelana nomthelela wayo.
Iphampu ye-Hydraulic plunger
Iphampu ye-hydraulic plunger incike kumfutho womoya ukuze inikeze uwoyela ethangini likawoyela we-hydraulic. Ngemuva kokuqala umshini ngaso sonke isikhathi, ithangi likawoyela we-hydraulic kufanele lifinyelele umfutho womoya osebenzayo ngaphambi kokusebenzisa umshini. Amaphampu e-Straight-axis swash plate plunger ahlukaniswe abe izinhlobo ezimbili: uhlobo lokuphakelwa kukawoyela ocindezelayo kanye nohlobo lukawoyela oziqalayo. Iningi lamaphampu anikezela uwoyela ocindezelayo asebenzisa ithangi likaphethiloli elinomfutho womoya, kanti amanye amaphampu asebenza ngogesi ngokwawo anepompo yokushaja ukuze anikeze uwoyela ocindezelayo endaweni yokungena kawoyela yephampu ye-hydraulic. Iphampu ye-self-priming hydraulic inekhono eliqinile lokuzibamba futhi ayidingi amandla angaphandle ukuhlinzeka ngowoyela.
Amafutha okucindezela wepompo ye-plunger eguquguqukayo angena emgodini ophansi we-variable displacement casing emzimbeni wepompo kanye nembobo kawoyela endaweni eguquguqukayo yesikhwama sepompo ngevalve yokuhlola. Lapho induku yokudonsa ishona phansi, i-servo piston iphushelwa phansi, bese i-servo valve Imbobo ye-valve ephezulu ivuliwe, futhi uwoyela ocindezelayo egumbini elingaphansi lendlu eguquguqukayo ungena ekamelweni eliphezulu lendlu eguquguqukayo ngokusebenzisa imbobo kawoyela. i-piston eguquguqukayo. Njengoba indawo yegumbi eliphezulu inkulu kunaleyo yegumbi elingaphansi, umfutho we-hydraulic uphusha i-piston ukuthi iye phansi, ishayela i-pin shaft ukwenza ikhanda eliguquguqukayo Lijikeleze phakathi nendawo yebhola lensimbi, shintsha i-angle yokuthambekela. kwekhanda eliguquguqukayo (ukwanda), futhi izinga lokugeleza kwepompo ye-plunger lizokhula ngokufanele. Ngokuphambene nalokho, lapho induku yokudonsa ihambela phezulu, i-angle yokuthambekela yekhanda eliguquguqukayo ishintsha ngokuphambene, futhi izinga lokugeleza kwepompo nalo lishintsha ngokufanele. Uma i-engeli yokuthamba ishintsha ibe uziro, ikhanda eliguquguqukayo lishintshela ku-engeli eyinegethivu, ukugeleza koketshezi kushintsha indawo, kanye nezimbobo zokungena nokuphumayo zephampu ziyashintsha.
