Umgomo wokusebenza wephampu ye-axial piston

④ I-cylinder bore kanye ne-plunger pair Ukuze ugweme ukugxiliswa kwengcindezi, umphetho wesilinda kufanele upholishwe futhi ube yindilinga; ukuze kwandiswe impilo yesevisi ye-cylinder, ezinye ze-piston bore zifakwe nge-alloy cylinder liner (Fig. f), kanti ezinye zimbozwe ngesendlalelo sokugqoka nge-sintering noma ezinye izindlela; ukuze kuncishiswe amandla angemuva, indawo ye-piston esetshenziselwa ukuvula i-groove annular [Fig. g (a)], kodwa manje kubonakala sengathi kulula ukubangela ukuthi i-plunger iboshwe, ngakho-ke i-plunger yokukhanya isetshenziswa kakhulu okwamanje . Ukuze unciphise isisindo, unciphise amandla e-inertia namandla e-centrifugal, futhi uthuthukise izici eziguquguqukayo zepompo, i-plunger ngokuvamile yenziwa ifomu elingenalutho elinesakhiwo esilula. Nokho, isilinda esingenalutho sandisa ivolumu “efile” engavumelekile kusilinda, esingakwazi ukuthuthukisa ukusebenza kahle kwevolumu nokunciphisa umsindo, ngakho ngokuvamile sigcwaliswa ngensimbi elula noma ipulasitiki elula [Fig. g (b)].

Ngaphezu kwalokho, ukuze kuncishiswe ukuvuza kwegebe lonyaka phakathi kwe-plunger ne-cylinder bore, ukucaciswa kwe-plunger bore ngokuvamile kulawulwa ngaphakathi kuka-0.02 ~ 0.04mm.

⑤ Uma uhambisa amafutha ngaphakathi nangaphandle, ipuleti le-valve kanye nepuleti le-valve elisizayo ebusweni bokugcina be-cylinder block kufanele ithwale i-eccentric load ye-cylinder block ngenxa yephutha lokunemba lokwengeza i-T kanye ne-torque etshekisayo isebenza. Uma imvume phakathi kobuso bokuphela kwesilinda kanye nepuleti ye-valve inkulu kakhulu, ukuvuza kuzokwenyuka futhi ukusebenza kahle kwe-volumetric kuzoncishiswa, ngaphandle kwalokho, ukuguga kwepuleti ye-valve kuzoqiniswa. Isimo esihle sokuxhumana ukuthi i-cylinder block imisiwe epuleti lokusabalalisa uwoyela.

Uma igebe eliphakathi kwepuleti le-valve nesilinda lingafani, lizokwandisa ukuguga kwepheya yobuso bokuphela kwepuleti levalvu kanye nesilinda, futhi kuthinte ukusebenza nempilo yesevisi yepompo. Ukuze ulawule imvume engalingani, izinyathelo ezilandelayo zithathwa esakhiweni se-valve plate noma i-cylinder block.

a. Ukusatshalaliswa kwendiza kubizwa ngokuthi ukusatshalaliswa kwendiza ngoba inhlanganisela yepuleti le-valve ne-cylinder block iyindiza. Lesi sakhiwo sinezinzuzo zokucubungula nokugcinwa kalula, isinxephezelo se-axial nokunye. Ngakho-ke, lesi sakhiwo sisetshenziswa kabanzi kumaphampu amancane naphakathi nendawo namamotho. Kumaphampu namamotho anokususwa okukhulu, esinye sezinyathelo ezintathu ezilandelayo ngokuvamile sithathwa ukuze kuvale igebe elingalingani: enye iwukusebenzisa ipuleti levalvu elintantayo [Fig. H (a)] ukunxephezela ngokuzenzakalelayo ukuntanta okuhlobene kwe-valve plate 1 nomkhono wokugeleza 5; enye iwukusebenzisa isilinda esintantayo [Fig. H (b)] ukunxephezela ngokuzenzakalelayo ukuntanta okuhlobene kwebhulokhi yesilinda 2 kanye nomkhono wokugeleza 5 Uma kuqhathaniswa, kulula ukucubungula futhi kulula ukukhetha isilinganiso sokuminyanisa, kodwa ukunyakaza kwe-inertia yebhulokhi yesilinda kuyenyuka, ukusebenza kokuziqondanisa akukuhle, kanye nokusebenza kokuzilungiselela kwephampu kuyathinteka; okwesithathu, ipuleti lenguquko elintantayo [Fig. I-H (c)] isetshenziselwa ukunxephezela ngokuzenzakalelayo ngokuntanta okuhlobene kwepuleti lenguquko 7 kanye nebhulokhi yesilinda 2, elungele ukucubungula nokugcinwa, kodwa ngesinxephezelo esincane.

Ngokusatshalaliswa kwevalvu yendiza, ngezinye izikhathi ungqimba lwethusi nezinye izinto ezivimbela ukukhuhlana (Fig. f) zisetshenziselwa ukumboza ubuso obuphansi bokugcina kwesilinda ukuze kuncishiswe ukuguga kwendawo ehlangene phakathi kwepuleti le-valve kanye nebhulokhi yesilinda.

b. Imbobo eyindilinga iboniswa kuMfanekiso I. njengoba inhlanganisela ye-port plate 1 ne-cylinder block 2 iyindilinga, ibizwa ngokuthi imbobo eyindilinga. Lesi sakhiwo sinokuma okuhle futhi singanxephezela ngokuzenzakalelayo. Kodwa ukucutshungulwa kwendawo eyindilinga kudinga okokusebenza okukhethekile, ukunemba okuphezulu nokugcinwa okungalungile.

Shiya imininingwane yakho futhi
sizokuthinta.
