I-hydraulic balance valve Excavator i-hydraulic cylinder valve core RPEE-LBN

Amaphutha avamile we-valve yokusiza yilezi: ukudlidliza nomsindo; Ingcindezi yokulungiswa iphansi, ukulungiswa kungasebenzi; Ukucindezela kokulungiswa kuphezulu, ukulungiswa kungasebenzi; Ukushintshashintsha kwengcindezi; Ukuvuza, njll. Izimbangela zalokhu kwehluleka nezindlela zokuxazulula izinkinga zimi kanje:

1. Ukudlidliza nomsindo

1) Umsindo we-fluid kufanele uthathwe ngokuya ngezizathu ezilandelayo:

(1) Umsindo we-Cavitation cavitation kanye nomsindo we-eddy wamanje kanye nomsindo we-shear fluid ngemuva kokuthi i-valve yokuchichima kufanele ishintshwe;

(2) Umsindo womthelela wegagasi lokucindezela ngesikhathi sokuthulula i-valve yokusiza kufanele ukhulise isikhathi sokuthulula, futhi umsindo we-high-frequency obangelwa ukusabalalisa okungalingani kwengcindezi ku-valve yokushayela kanye ne-valve yesilayidi eyinhloko kufanele ithuthukise ukunemba kwejometri. we-valve, wandise ububanzi bepayipi likawoyela elibuyayo, khetha isiphethu se-valve eyinhloko ethambile kanye ne-viscosity efanele yepayipi lokubuyisela uwoyela ngomoya, kufanele uhlole uphawu nokukhipha umoya. Uma ingcindezi yangemuva epayipini likawoyela obuyayo inkulu kakhulu, ububanzi bepayipi likawoyela elibuyayo kufanele linyuswe futhi ipayipi likawoyela elibuyayo kufanele limiswe ngokuhlukana.

(3) Ivalvu yokukhulula indawo yokulawula ingcindezi yangaphakathi emoyeni, kufanele ihlole isivalo kanye nokugeleza kwe-exhaust kudlula inani elivumelekile, kufanele kukhethwe ukuze kufane nokugeleza kwevalvu yokukhulula.

2) Umsindo wemishini, izinyathelo ezihambisanayo kufanele zithathwe ngokuya ngezizathu ezilandelayo:

I-valve yesilayidi kanye nembobo ye-valve kuqine kakhulu noma kuxege kakhulu ukuze kubangele ukudlidliza nomsindo, kufanele ihlole futhi ilungise isiphethu esilawula ukucindezela sithambile kakhulu noma sikhubazekile ukukhiqiza umsindo, kufanele sithathele indawo intwasahlobo elawula ukucindezela.

Uma i-nati elawula ukucindezela ikhululekile, kufanele iqiniswe futhi i-valve ye-taper kufanele iguge, kufanele ilungiswe ngesikhathi ukuze ikhiqize umsindo we-resonance nezinye izingxenye zesistimu, futhi kufanele kubhekwane nayo ngesikhathi ukuze kuqedwe i-resonance.
