Yekutanga Sauer Danfoss Mavhavha MCV116 Series

Iyo MCV116 Pressure Control Pilot (PCP) Valve ivharuvhu isingadhure yekushandisa mumagetsi emagetsi anodzora michina inoshandiswa mukuvaka, kurima, kubata zvinhu, marine, migodhi uye maindasitiri maapplication. Chishandiso ichi chakagadzirirwa kudzora mavharuvhu anofambiswa nendege (proportional main spool valves mu5-50 gpm range), pilotoperated variable displacement pumps and motors and any other device which is pilot differential pressure actuated. Iyo PCP ndeye torque-motor actuated, kaviri-nozzle flapper vharafu iyo inoburitsa yakasarudzika yekubuda kudzvanywa inoenderana neyakaiswa magetsi ekuisa chiratidzo. Iyo imwe-nhanho, yakamira, yakavharwa loop pressure control valve inoshandisa mukati me hydraulic pressure

Iyo PCP inogamuchira dc ikozvino uye inogadzira yakaenzana hydraulic differential pressure output. Ona iyo Internal Workings Schematic. Input current inodzora torque mota nhanho, network yebhiriji ine armature yakaiswa pane torsion pivot uye yakamiswa mugero remhepo remagineti. Magineti maviri echigarire akaporeswa akaenzanirana uye ndiro yekubatanidza inoumba furemu yebhiriji remagineti.

Pakushata, armature iri pakati pemukaha wemhepo pakati pemagineti anopikisana mapango nekuenzana kwesimba remagineti uye null-adjust centering springs. Sezvo yekuwedzera ikozvino inokwira, magumo ezvombo anove akarerekera kuchamhembe kana kumaodzanyemba, zvichienderana negwara rezvino. Iyo inokonzeresa armature kufamba inotarirwa neamperage yekudzora ikozvino, chitubu chinogara uye mutsauko wekumanikidza mhinduro masimba (anotsvaga torque chiyero, sezvakatsanangurwa pazasi). Linearity yehukama hwekupinza / kubuda huri pasi pe10% kuburikidza ne80% yeyakayerwa ikozvino.

Iyo magineti bhiriji kubuda, iyo flapper torque, iyo inodzora iyo hydraulic bhiriji reshiyo. Pakushaikwa, flapper iri pakati pemanozzles maviri. Kumusoro kubva kumhuno yega yega kune orifice inopa kudonha kwezita rekudzvanya kana sisitimu yapera. Pakati pemhuno negonhi padivi rega rega pane chiteshi chekutonga. Sezvo torque inoshandura flapper kubva kune imwe muromo ichienda kune imwe, mutsauko wekudzora dzvinyiriro inoguma, iyo yakakwira divi iri iyo iri pedyo neflapper.

Iyo PCP ndeye yakavharwa-loop pressure control valve inoshandisa mukati hydraulic pressure reactions kuti iite intrinsic mhinduro. Nekupinza nhanho kubva kwazvino kunobva, flapper inotanga yakananga kuzere sitiroko kuvhara iyo (yakarairwa) yepamusoro-padivi muromo. Fluid pressure inokwira kudivi rino uye inofambisa flapper kumashure ichienda ku null. Kana iyo torque inobuda kubva kumota yakaenzana ne torque inobuda kubva mukumanikidza mhinduro, iyo system iri mukuenzanisa. Deferential pressure inobva yaenzana nekuraira ikozvino.
