Sauer yoqobo Danfoss Valves MCV116 Series

I-MCV116 i-Pressure Control Pilot (PCP) iValve yivalve yokulawula engabizi kakhulu yokusetyenziswa kwiinkqubo ze-electrohydraulic ezilawula oomatshini abasetyenziselwa ukwakha, ukulima, ukuphatha izinto eziphathekayo, elwandle, kwimigodi kunye ne-industrial applications. Isixhobo siyilelwe ukulawula iivalvu zolawulo lokuqukuqela eziqhutywa ngumqhubi (iivalufa ezilinganayo ezingundoqo ze-spool kuluhlu lwe-5—50 gpm), iimpompo zokufuduswa eziguquguqukayo eziqhutywa ngepilotopeed kunye neenjini kunye naso nasiphi na esinye isixhobo esinoxinzelelo lolwahlulo lokulinga olusebenzayo. I-PCP yi-torque-motor actuated, i-valve ye-flapper ene-nozzle ephindwe kabini evelisa i-different output pressure ngokomlinganiselo wesignali yegalelo lombane elisetyenzisiweyo. Yinqanaba elinye, elizimeleyo, elivaliweyo lokulawula uxinzelelo lwevalve esebenzisa uxinzelelo lwangaphakathi lwehydraulic

Ithiyori yokuSebenza

I-PCP yamkela i-dc yangoku kwaye ivelise i-proportional hydraulic differential pressure output. Jonga iSicwangciso sokuSebenza saNgaphakathi. Igalelo langoku lilawula inqanaba lemotor yetorque, uthungelwano lwebhulorho equka iarmature exhonywe kwipivot ye-torsion kwaye ixhonywe kumsantsa womoya womhlaba wemagnethi. Iimagnethi ezimbini ezisisigxina ezipolarized ngokunxuseneyo kunye nepleyiti yokudibanisa yenza isakhelo sebhulorho kazibuthe.

Kwi-null i-armature igxile kwisithuba somoya phakathi kweepali zemagnethi ezichasayo ngokulingana kwamandla azo wemagnethi kunye nemithombo ephakathi e-null-adjust. Njengoko igalelo langoku linyuka, isiphelo se-armature siba sicala ukuya ngasentla okanye emazantsi, kuxhomekeke kwicala langoku. Isiphumo sokuhamba kwe-armature sichongwa yi-amperage yolawulo lwangoku, i-spring constant kunye ne-different pressure feedback forces (efuna i-torque balance, njengoko kuchazwe ngezantsi). Umgca we-input/output relationship ungaphantsi kwe-10% ukuya kwi-80% yangoku.

Imveliso yebhulorho yamagnetic, i-torque ye-flapper, ilawula umlinganiselo webhulorho ye-hydraulic. Kwi-null, i-flapper iphakathi phakathi kwemibhobho emibini. Umsinga osuka phezulu kumbhobho ngamnye kukho i-orifice enikezela ukuhla koxinzelelo lwegama xa isixokelelwano singasebenzi. Phakathi kwe-nozzle kunye ne-orifice kwicala ngalinye kukho i-port yokulawula. Njengoko i-torque isusa i-flapper isuka kwenye i-nozzle isiya kwelinye, iziphumo zoxinzelelo lolawulo oluhlukeneyo, icala eliphezulu lilo elikufutshane ne-flapper.

I-PCP yivalve yokulawula uxinzelelo lwe-loop evaliweyo isebenzisa iimpendulo zangaphakathi zoxinzelelo lwe-hydraulic ukwenza ingxelo yangaphakathi. Ngenyathelo lenyathelo elisuka kumthombo wangoku, i-flapper iqala ihambela kwi-stroke epheleleyo ukuvala (eyalelwe) umbhobho wecala eliphezulu. Uxinzelelo lwe-fluid lukhuphuka kweli cala kwaye lubuyisela i-flapper ngasemva ukuya kwi-null. Xa i-torque ephuma kwi-motor ilingana ne-torque ye-torque evela kwimpendulo yoxinzelelo, inkqubo ilingana. Uxinzelelo lweDeferential ke ngoko lulungelelwaniso lomyalelo wangoku.
