Ivalve ye-hydraulic balance valve Excavator hydraulic cylinder valve core RPEE-LBN

Iimpazamo eziqhelekileyo zevalve yokunceda zezi: ukungcangcazela kunye nengxolo; Uxinzelelo lokulungelelanisa luphantsi, ukulungiswa akusebenzi; Uxinzelelo lohlengahlengiso luphezulu, ukulungiswa akusebenzi; Ukuguquguquka koxinzelelo; Ukuvuza, njl njl. Unobangela woku kusilela kunye neendlela zokusombulula ingxaki zezi zilandelayo:

1. Ukungcangcazela kunye nengxolo

1) Ingxolo yolwelo kufuneka ithathwe ngokwezi zizathu zilandelayo:

(1) Ingxolo ye-Cavitation cavitation kunye ne-eddy current kunye ne-shear fluid fluid emva kokuba i-valve yokuphuphuma kufuneka itshintshwe;

(2) Isandi sempembelelo yamaza oxinzelelo ngexesha lokuthuthwa kwevalve yokukhulula kufuneka sandise ixesha lokukhulula, kunye nesandi esiphezulu se-frequency ebangelwa ukusabalalisa ngokungalingani koxinzelelo kwivalve yokuqhuba kunye nevalve yesilayidi engundoqo kufuneka iphucule ukuchaneka kwejometri. wevalve, ukwandisa ububanzi bombhobho we-oyile yokubuya, khetha isiphethu sevalve ethambileyo engundoqo kunye ne-viscosity efanelekileyo yombhobho wokubuyiswa kwe-oyile kunye nomoya, kufuneka uhlolisise itywina kunye nokukhupha. Ukuba uxinzelelo lwangasemva kumbhobho we-oyile yokubuyisela lukhulu kakhulu, i-diameter ye-oyile yokubuyisela i-oyile kufuneka inyuswe kwaye umbhobho we-oyile yokubuyisela kufuneka ubekwe ngokwahlukileyo.

(3) Ivalve yokukhulula indawo yokulawula uxinzelelo lwangaphakathi emoyeni, kufuneka ihlolisise isitywina kunye nokuphuma kwamanzi kudlula ixabiso elivumelekileyo, kufuneka kukhethwe ukuhambelana nokuhamba kwevalve yokunceda.

2) Ingxolo yoomatshini, amanyathelo ahambelanayo kufuneka athathwe ngokwezi zizathu zilandelayo:

Ivalve yesilayidi kunye nomngxuma wevalvu zixinene kakhulu okanye zikhululekile kakhulu ukuba zibangele ukungcangcazela nengxolo, kufuneka zikhangele kwaye zilungise intwasahlobo elawulayo yoxinzelelo ithambile kakhulu okanye ikhubazekile ukuba ivelise ingxolo, kufuneka ithathe indawo yoxinzelelo olulawula intwasahlobo.

Ukuba i-nut yokulawula uxinzelelo ikhululekile, kufuneka iqiniswe kwaye i-valve ye-taper kufuneka igugile, kufuneka ilungiswe ngexesha lokuvelisa ingxolo ye-resonance kunye namanye amacandelo enkqubo, kwaye kufuneka iqhutywe ngexesha lokuphelisa i-resonance.
