I-TM70301 i-proportional solenoid valve hydraulic pump excavator izincedisi

Ivalve ye-screw cartridge yivalvu edityanisiweyo ye-electromagnetic proportional cartridge emiswe kwibloko yendibano yesekethe ye-oyile. I-valve ye-screw cartridge ineempawu zesicelo esiguquguqukayo, ukugcinwa kombhobho kunye nokubunjwa kwemithi ephantsi, njl njl. Isetyenziswe ngokubanzi nangakumbi kumatshini wokwakha kwiminyaka yamuva. Iqhele ukusetyenziswa spiral cartridge uhlobo ivelufa ngokomlinganiselo une ezimbini, ezintathu, ezine kunye neefomu zokudlula ezininzi, indlela ezimbini ivelufa proportional ivelufa main ivelufa throttle ivelufa, ngokufuthi amacandelo ayo kunye ukwenza ivelufa composite, flow, ulawulo uxinzelelo; Amakhonkco amathathu
Ivalve yolungelelwaniso yeyona valve yokunciphisa uxinzelelo, ekwayeyona isetyenziswa kakhulu ivelufa yolungelelwaniso kwinkqubo ye-hydraulic ye-mobile mechanical, esebenza ikakhulu i-hydraulic multiway valve pilot oil circuit. Ivalve yokunciphisa i-valve eneendlela ezintathu zokulinganisa i-pressure ingathatha indawo ye-valve yesiqhelo yokunciphisa i-valve ye-pilot, enokuguquguquka ngakumbi kunye nokuchaneka kokulawula okuphezulu kune-valve ye-pilot manual. Ingenziwa kwi-proportional servo manual manual multi-way valve njengoko kubonisiwe kwi-Figure 1. Ngemiqondiso eyahlukeneyo yokufaka, i-valve yokunciphisa uxinzelelo yenza ukuba i-piston ephumayo ibe noxinzelelo oluhlukeneyo okanye izinga lokuhamba ukuze kuphunyezwe ulawulo olulinganayo lokufuduka kwezinto ezininzi. indlela ivalve spool. Iivalvu ezilinganayo zekhatriji zeendlela ezine okanye ezininzi zinokulawulwa ngokuzimeleyo kwisixhobo esisebenzayo.
Ivalve yesilayidi yohlobo lwesilayidi, ekwabizwa ngokuba yivalve yokuhambisa, yenye yezona zinto zisisiseko zenkqubo yomatshini womatshini wokuhambisa amanzi, enokuqonda isalathiso kunye nolawulo lokuhamba kwevalve edibeneyo.
Ivalve ye-electro-hydraulic slide valve proportional multiway valve yeyona nto ifanelekileyo yokulawula ukuguqulwa kwe-electro-hydraulic, igcina umsebenzi osisiseko wevalve yendlela yeendlela ezininzi, kodwa ikwanyusa indawo yokusebenza kombane ngokulinganayo kwe-servo kunye nokuziva umthwalo kunye nezinye iindlela zolawulo oluphambili, yimveliso yokutshintsha ivalvu ngoomatshini bokwakha.
Ngenxa yokuqwalaselwa kweendleko zokuvelisa kunye neemfuno zokulawula ukuchaneka komatshini wokwakha azikho iimpawu eziphezulu, i-valve ye-proportional ye-multi-way valve ayinakuxhotyiswa nge-sensor yokufuduka, kunye nokufumanisa i-elektroniki kunye nemisebenzi yokulungiswa kweempazamo. Ukufuduswa kwe-spool kuchaphazeleka lula ngokuguquguquka koxinzelelo olubangelwa utshintsho lomthwalo, kwaye ukubonwa okubonakalayo kuyadingeka ukuze kuqinisekiswe ukugqitywa komsebenzi ngexesha lokusebenza. Ulawulo lwe-elektroniki, ukusebenza kokulawula kude kufuneka kuhlawule ingqalelo ngakumbi kwimpembelelo yokuphazamiseka kwangaphandle. Kutshanje, ngophuhliso lwetekhnoloji ye-elektroniki, abantu basebenzisa ngakumbi nangakumbi ukupakishwa kwangaphakathi
Izinzwa zokufuduka ezifana ne-dynamic transformer (LDVT) zisetyenziselwa ukufumanisa ukuhamba kwendawo ye-spool kunye nokuqaphela ulawulo oluvaliweyo lwe-spool displacement. Le valve idityaniswe kakhulu ibandakanya ivalve ye-solenoid elinganayo, isivamvo sengxelo yesikhundla, iamplifier yedrive kunye nezinye iisekethe zombane.
