Hydraulic valvụ valvụ eriri eriri katrij valvụ LF12 valvụ nchịkwa na-efe efe LNV-12

The threaded cartridge valve valve bụ rotary mounted cartridge valve, nke a na-agbanye n'ime oghere nke eriri mmanụ site na nkwụnye ya na eri nke ya (dị ka egosiri) nke mere na nhazi nke usoro nhazi nke hydraulic dị mgbagwoju anya, olu ya. dị obere, dị arọ karị, ịghasa eri na akara iji mepụta akara siri ike nwere ike hụ na sistemu hydraulic anaghị agbapụta mmanụ. Ya mere, n'ihi na nke efu leakage ya, elu unit olu njupụta, obere ohere, mfe igbasa na dochie, na-eri-irè, nwere ike jikọọ ozugbo na actuator (dị ka hydraulic cylinder, moto) mbubata na mbupụ akụkụ, mfe ntinye na debugging. na uru ndị ọzọ, site na nleba anya ụlọ ọrụ hydraulic ụlọ na nke mba ọzọ. Ọgụgụ 2 na-egosi ngwa ngwa nke Vickers screw insert valvụ na ngwaọrụ mgbapụta nke Sany Construction Machinery. E gosipụtara ụkpụrụ ọrụ ya na FIG. 1.b. Mgbe piston na-achọ iru ebe njedebe ma gafee ọdụ ụgbọ mmiri A, n'ihi mmetụta na-akụda mmụọ nke oghere damping, a na-emepụta ihe dị iche iche nrụgide na nsọtụ abụọ nke valvụ cartridge spool, nke mere na ọdụ ụgbọ mmiri C na-enye mmanụ nchịkwa na-atụgharị, na mgbe ahụ. site na damping nke valvụ mmiri na-agbapụta mmanụ, a na-arụ nrụgide iji kwọọ onye na-anya ụgbọ mmiri obere valvụ hydraulic nke valvụ na-agbagharị ụzọ anọ, na-eme ka ntụgharị nke valvụ swing na-emecha ma mechaa ihe mgbapụta ahụ ọkara okirikiri nke hydraulic commutation.
 

Ebe ọ bụ na SANY concrete pumping engineering machinery adopts a single loop hydraulic system (ya bụ, ihe nkesa valvụ cylinder na cylinder na-agbapụta n'otu aka ahụ), isi ihe dị na usoro a bụ ka esi aghọta ihe omume akpaka nke valvụ nkesa ihe. cylinder na pumping master cylinder, ya mere, isi cylinders abụọ nke ngwaọrụ mgbapụta nke Sany Drag pump na pump truck na-onwem na valvụ eriri eriri eri (Figure 2.). Nye akara njikwa nrụgide, nke mere na ọrụ mgbapụta ihe na-aga n'ihu na usoro ziri ezi na oge, ya bụ, sistemu hydraulic n'onwe ya iji mezue mgbapụta nna ukwu cylinder na nkesa valvụ cylinder nke ntụgharị ọzọ nke okirikiri ebugharị hydraulic zuru oke, ghọta nke ọma. ọrụ mmịpụta na nri mgbanaka.
