Ivalve engundoqo ye-E320B ye-excavator 171-0030 E320 yokhuseleko

I-valve yokunceda i-valve yokulawula uxinzelelo lwe-hydraulic, eyona nto idlala indima yokunciphisa uxinzelelo, ukulawulwa koxinzelelo, ukukhulula inkqubo kunye nokukhusela ukhuseleko kwizixhobo ze-hydraulic. Kwi-quantitative pump throttling regulation system, ipompo yobungakanani inikeza ukuhamba rhoqo, xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iya kuncitshiswa, ngeli xesha i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okungaphezulu kubuyele kwitanki, ukuqinisekisa ukuba Uxinzelelo lwe-valve yokungena, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhleli. I-valve yokunceda idibaniswe ngokulandelelana kwisekethe ye-oyile yokubuya, kwaye ukuzinza kweendawo ezihambayo zoxinzelelo lwangasemva kwe-valve yokunceda kwanda. Umsebenzi wokukhulula wenkqubo kukudibanisa i-valve ye-solenoid kunye ne-flow flow encinci kwi-series kwi-remote control port ye-valve yokunceda. Xa i-electromagnetic ine-energy, i-remote control port yevalve yokukhulula idlula kwitanki yamafutha. Ngeli xesha, ipompo ye-hydraulic ikhutshwe kwaye i-valve yokunceda isetyenziswe njenge-valve yokukhulula. Umsebenzi wokukhusela ukhuseleko, xa inkqubo isebenza ngokuqhelekileyo, i-valve ivaliwe, kuphela xa umthwalo udlula umda ochaziweyo, ukugqithisa kuvulwa, kwaye ukukhuselwa kokugqithiswa kwenziwa, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kwandiswa.

Ivalve yokukhulula, ivalve yokulawula uxinzelelo lwehydraulic. Ikakhulu idlala indima yoxinzelelo oluqhubekayo kunye nokukhuselwa kokhuseleko kwizixhobo ze-hydraulic. Uxinzelelo oluqhubekayo lwempembelelo yoxinzelelo: Kwinkqubo yokulawula ipompo yokulinganisa, ipompo yobungakanani inika umyinge wokuhamba rhoqo. Xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iya kuncipha. Ngeli xesha, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okugqithisiweyo kubuyele kwi-tank, ukuqinisekisa ukuba i-valve yokunceda i-inlet yoxinzelelo, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhlala (i-valve port ivame ukuvulwa ngokuguquguquka koxinzelelo) . Amacandelo alula ukuvelisa ingxolo kwizixhobo ezisebenza ngoxinzelelo olukhulu olwenziwa ngamanzi athathwa ngokuba ziimpompo kunye neevalvu, kwaye iivalvu zilawulwa ikakhulu ziivalvu zokukhulula kunye neevalvu ze-electromagnetic directional directional. Zininzi izinto ezivelisa ingxolo. Ingxolo yevalve yokunceda ineentlobo ezimbini: isandi sesantya kunye nesandi somatshini. Ingxolo kwisandi sesantya sibangelwa ikakhulu kukungcangcazela kweoli, i-cavitation kunye ne-hydraulic shock. Isandi somatshini sibangelwa ikakhulu yimpembelelo kunye nokukhuhlana kwamalungu kwi-valve.
