Ukuze kusonjululwe ingxaki yokuba iimpawu zokuqukuqela zohlobo lweplunger ivelufa elungelelanisiweyo yokulawula eyilwe ngefomula yobungqina zitenxa kakhulu kumgca othe ngqo olindelekileyo, isikimu sokwandisa ubume bespool sohlobo lweplunger elawula ivelufa ibekwe phambili. Iskimu sithatha i-flow coefficient kunye ne-flow coefficient increment njengeenqobo zokuvavanya i-linear fit degree, ithatha uvavanyo lovavanyo njengesiseko kunye nokulinganisa kwamanani njengendlela ephambili yokulungelelanisa kunye nokwandisa isakhiwo se-spool inyathelo ngenyathelo, kwaye iqinisekisa ingqiqo kunye nokuchaneka kwesikimu ngokulinganisa kwamanani. Iziphumo zibonisa ukuba ulwakhiwo oluphuculweyo lwe-spool lwenza iimpawu zokuhamba zilungele kakhulu umgca othe tye, kwaye ukuphambuka kwe-coefficient yokuhamba ukusuka kwixabiso lethiyori ekuvuleni ngakunye kuncitshiswe ukusuka ngaphezu kwe-8% ukuya ngaphantsi kwe-2%. Ukuphambuka kokunyuka kwe-flow coefficient increment ukusuka kwixabiso lethiyori ngaphambi kokulungiswa kuninzi ngaphezu kwe-15%, kwaye ubuninzi bufikelela kwi-63.26% yehla ukuya ngaphantsi kwe-5%, kwaye ixabiso eliphezulu laliyi-13.62 kuphela.

I-valve ye-spherical pair sesinye sezakhiwo ezisetyenziswa ngokuqhelekileyo zoxinzelelo oluphezulu kunye nempompo enkulu yepiston yokuhamba kunye nesakhiwo esihlangeneyo, indawo enkulu yokuthwala kunye nokukwazi ukuxhathisa umzuzu wokubhukuqa. Ukuvavanywa kokuthembeka kwayo yinxalenye ephambili yokuthembeka kwempompo yepiston. Indlela yokuvavanya ukuthembeka kokuqhekeka kokudinwa kunye nokuthotywa kokuthotywa kweeperical valve pairs kunye neAngile yokuthambeka ethile yeplunger iyacetywa. Imodeli yokuhanjiswa kwefilimu yeoli yeperile yevalve yasekwa, kwaye ukubonakaliswa koxinzelelo lwebhanti yokutywina yangaphakathi nangaphandle yafunyanwa ukuze kuqondwe uhlalutyo lwamandla esibini sevalve. Ngokusebenzisa imodeli yokulinganisa i-ANSYS kunye nohlalutyo lwekhonkco elibuthathaka lebhloko ye-cylinder, uhlalutyo lokuthembeka kokukhathala kwebhloko ye-cylinder lwenziwa ngokusekelwe kwi-criterion Miner. Ukuthembeka kokunxiba kweperi yepleyiti engqukuva kubalwa ngokusekelwe kwithiyori yeGaussian eguqukileyo. Ekugqibeleni, ukuthembeka kokukhathala kunye nokuthembeka kokugqoka kudibaniswa ukuze kufundwe ukuthembeka okupheleleyo. Iziphumo zibonisa ukuba elona khonkco libuthathaka lesibini sevalve ye-axial piston pump ene-inclined plunger yikona ebukhali yojongano lwemingxuma ephezulu kunye nephantsi yoxinzelelo. Ngaphantsi kwemeko yoxinzelelo olunikiweyo, izinga lokusinda liyi-50%, amaxesha omjikelezo ophantsi kakhulu wesixhobo ngu-4.839 × 109, kwaye ubomi bebhloko ye-cylinder yi-31 839.52 h. Umyalelo wobungakanani bomjikelezo woxinzelelo jikelele uhambelana nomyalelo wobungakanani bomjikelo ngokukhathala kunye nokuthembeka kokugqoka, ngoko ukuthembeka okupheleleyo kuyancipha xa ukuthembeka okuninzi kudibaniswa.
