Izincedisi zomlayishi we-excavator 209-60-77290 indibano yevalve ye-solenoid

Ivalve ye-electromagnetic ye-excavator idlala indima yokulawula.

I-1, i-valve ye-solenoid sisixhobo semizi-mveliso esilawulwa yi-electromagnetic, isetyenziselwa ukulawula izinto ezisisiseko ze-automation fluid, yeye-activator, engaphelelanga kwi-hydraulic, i-pneumatic. Isetyenziswe kwiinkqubo zokulawula i-industrial ukulungelelanisa isalathiso seendaba, ukuhamba, isantya kunye nezinye iiparamitha.

I-2, i-valve ye-solenoid inokudibaniswa kunye neesekethe ezahlukeneyo ukufezekisa ulawulo olufunwayo, kwaye ukuchaneka kunye nokuguquguquka kokulawula kunokuqinisekiswa. Kukho iintlobo ezininzi ze-solenoid valves, iivalve ze-solenoid ezahlukeneyo zidlala indima kwizikhundla ezahlukeneyo zenkqubo yokulawula, ezona ziqhelekileyo zisetyenziselwa ukutshekisha, i-valve yokukhusela, i-valve yokulawula i-directional, i-speed regulating valves njalo njalo.

Isebenza njani ivalve elinganayo

Ulawulo oluzenzekelayo lunokwahlulwa lube lulawulo lwethutyana kunye nolawulo oluqhubekayo. Ulawulo lwethutyana lulawulo lokutshintsha. Kwinkqubo yokulawula i-pneumatic, i-valve yokubuyisela i-ON-OFF ene-frequency ephantsi yokusebenza isetyenziselwa ukulawula ukuphuma kwendlela yegesi. Thembela kwi-valve yokunciphisa uxinzelelo ukulungelelanisa uxinzelelo olufunekayo, uthembele kwi-valve ye-throttle ukulungelelanisa ukuhamba okufunekayo. Le nkqubo yokulawula umoya wendabuko ifuna ukuba nezixhobo ezininzi zokukhupha kunye nezantya zokushukuma ezininzi, idinga iivalve zokunciphisa uxinzelelo oluninzi, i-throttle valves kunye ne-valve yokubuyisela umva. Ngale ndlela, kungekhona kuphela amacandelo adinga ngaphezulu, ixabiso liphezulu, ukubunjwa kwenkqubo kuyinkimbinkimbi, kwaye amaninzi amacandelo kufuneka alungiswe ngesandla kwangaphambili. Ulawulo lwevalvu yombane yombane lololawulo oluqhubekayo, oluphawulwa lutshintsho lobuninzi bemveliso kunye nobungakanani begalelo (ixabiso langoku okanye ixabiso le-voltage), kwaye kukho ubudlelwane obulinganayo phakathi kwemveliso kunye nobungakanani begalelo. Ulawulo olulungelelanisiweyo lunokwahlulwa lube lulawulo oluvulekileyo lwelophu kunye nolawulo oluvaliweyo. Ulawulo oluvaliweyo lwenkqubo yengxelo yomqondiso. Ivalve ye-electro-hydraulic proportional valve yi-proportional electromagnet igalelo lamandla ombane kwivalve ukuvelisa isenzo esihambelanayo, ukwenzela ukuba ivalve esebenzayo i-spool displacement, i-valve port size sitshintshe kwaye igqibezele uxinzelelo kunye nemveliso ye-flow output ngokulingana nombane wegalelo. Ukufuduswa kwe-spool nako kunokondliwa ngoomatshini, ngokwenziwa ngamanzi okanye ngombane. Ivalve ye-electro-hydraulic proportional valve ineefom ezahlukeneyo, kulula ukuyisebenzisa umbane kunye nolawulo lwekhompyuter kwiinkqubo ezahlukeneyo ze-electro-hydraulic, ukuchaneka kolawulo oluphezulu, ukufakwa okuguquguqukayo kunye nokusetyenziswa, kunye nekhono elinamandla lokuchasana nongcoliseko, kunye nezinye iingenelo, intsimi yesicelo iyanda. . Ivalve yombane yokulinganisa ukhetho oluzenzekelayo kunye nokuqokelela, i-R & D kunye nokuveliswa kwevalve ye-cartridge ye-proportional kunye ne-valve ye-multiway elinganayo iqwalasela ngokupheleleyo iimpawu zokusetyenziswa koomatshini bokwakha, kunye nokulawula umqhubi, ukuva umthwalo kunye nemisebenzi yembuyekezo yoxinzelelo. Kubaluleke kakhulu ukuphucula umgangatho wobugcisa ngokubanzi koomatshini behydraulic abahambahambayo. Ngokukodwa, i-electronic control pilot operation, i-wireless remote control kunye ne-wireless remote control operation ibonise amathuba amahle okusebenza. Umgaqo: I-input signal iyanda, i-valve ye-solenoid pilot valve i-1 ibuyele, kunye ne-valve ye-solenoid yokukhupha i-7 ikwimeko yokusetha kwakhona, emva koko uxinzelelo lomoya lungena kwigumbi lomqhubi we-5 ukusuka kwi-SUP port nge-valve 1, uxinzelelo. kwigumbi lomqhubi wenqwelomoya liyanyuka, uxinzelelo lwegesi lusebenza kwindawo ephezulu ye-diaphragm 2, emva koko i-valve core 4 edityaniswe ne-diaphragm 2 iyavulwa, i-valve ye-3 yokuphuma ivaliwe, kwaye uxinzelelo oluphumayo luyenziwa. Olu xinzelelo lwemveliso lutyiswa emva kokulawula i-loop 8 ngokusebenzisa inzwa yoxinzelelo 6. Apha, uthelekiso olukhawulezayo lwenziwa kunye nexabiso elijoliswe kuyo kuze kube yilapho uxinzelelo lwemveliso lulingana nomqondiso wegalelo, okubangelwa utshintsho kwimveliso yoxinzelelo oluhambelana notshintsho kwi uphawu longeniso. Ngenxa yokuba akukho sixhobo se-nozzle baffle, ivalve ayikhathaleli kubumdaka kwaye inokuthembeka okuphezulu.
