Vavu ya Hydraulic Vavu ya Throttle valve yolumikizidwa ndi cartridge LF12 Vavu yowongolera yoyenda LNV-12

Valve ya cartridge yokhala ndi ulusi ndi valavu ya cartridge yozungulira, yomwe imakulungidwa mu dzenje lamafuta ndi plug-in ndi ulusi wake (monga momwe zasonyezedwera) kuti kapangidwe kake ka hydraulic system kakhale kocheperako, voliyumu yake. ndi yaying'ono, yopepuka kulemera, wononga ulusi pa chisindikizo kuti ipange chisindikizo cholimba imatha kuwonetsetsa kuti ma hydraulic system sataya mafuta. Chifukwa chake, chifukwa cha kutayikira kwake kwa zero, kuchuluka kwa voliyumu yayikulu, malo ang'onoang'ono, osavuta kugawa ndikusintha, okwera mtengo, amatha kulumikizidwa mwachindunji ndi chowongolera (monga hydraulic cylinder, motor) kulowetsa ndi kutumiza kunja, kukhazikitsa kosavuta ndi kukonza zolakwika. ndi zabwino zina, ndi chidwi chamakampani apanyumba ndi akunja a hydraulic. Chithunzi 2 chikuwonetsa kagwiritsidwe ntchito ka Vickers screw insert valavu mu makina opopera konkriti a Sany Construction Machinery. Mfundo yake yogwirira ntchito ikuwonetsedwa mu FIG. 1.b. Pamene pisitoni yatsala pang'ono kufika kumapeto ndikudutsa doko A, chifukwa cha kusungunuka kwa dzenje lotayirira, kusiyana kwapakati kumapangidwira kumapeto kwa cartridge valve spool, kotero kuti doko C limapereka mafuta obwezeretsa, ndiyeno. Kupyolera mu kusungunuka kwa valve yokhetsa mafuta, kupanikizika kumapangidwira kuyendetsa woyendetsa pang'ono valavu ya hydraulic valve ya swing-way-way valve, zomwe zimabweretsa kusintha kwa valve yogwedeza ndikumaliza kupopera konkire Theka la kuzungulira kwa hydraulic commutation.
 

Popeza makina opangira makina opangira konkriti a SANY amatenga njira imodzi yolumikizira ma hydraulic system (ndiko kuti, silinda yogawa konkire ndi silinda yopopera zili mulupu womwewo), chinsinsi cha dongosololi ndimomwe mungadziwire kutsata kotsatizana kwa valavu yogawa konkire. silinda ndi silinda yamphamvu yopopa, kotero ma silinda akulu akulu a chipangizo chopopera cha Sany kukoka mpope ndi galimoto yapampope ali ndi mavavu opangidwa ndi ulusi (Chithunzi 2.). Perekani chizindikiro chowongolera mphamvu, kuti ntchito yopopera konkire ikugwira ntchito yolondola komanso yanthawi yake, ndiye kuti, ma hydraulic system okha kuti amalize silinda yapampu yamadzi ndi silinda yogawa valavu yakusintha kwina kwa hydraulic commutation cycle, kuzindikira bwino. mphete ya kuyamwa ndi kudyetsa.
