Lub proportional valve ua haujlwm li cas

Kev tswj tsis siv neeg tuaj yeem muab faib ua kev tswj tsis tu ncua thiab kev tswj tsis tu ncua. Intermittent control yog hloov pauv. Nyob rau hauv lub pneumatic tswj system, ib tug ON-OFF reversing valve nrog ib tug tsawg khiav hauj lwm zaus yog siv los tswj lub on-off ntawm cov roj txoj kev. Cia siab rau lub siab txo lub valve los kho lub siab xav tau, tso siab rau lub valve kom kho qhov xav tau ntws. Qhov kev tswj hwm pneumatic ib txwm xav kom muaj ntau lub zog tso tawm thiab ntau qhov kev txav nrawm, nws xav tau ntau lub siab txo li qub, lub valve kaw thiab thim rov qab li qub. Nyob rau hauv txoj kev no, tsis tsuas yog lub Cheebtsam xav tau ntau tshaj, tus nqi yog siab, muaj pes tsawg leeg ntawm lub system yog complex, thiab ntau yam yuav tsum tau manually kho ua ntej. Kev tswj hluav taws xob proportional valve belongs rau kev tswj tsis tu ncua, uas yog tus cwj pwm los ntawm cov zis ntau hloov pauv nrog cov khoom siv nkag (tus nqi tam sim no lossis tus nqi hluav taws xob), thiab muaj qee qhov kev sib raug zoo ntawm cov zis thiab cov khoom tawm. Kev tswj qhov sib npaug tuaj yeem muab faib ua qhov qhib voj tswj thiab kaw lub voj kaw. Kaw-loop tswj ntawm lub teeb liab tawm tswv yim system. Electro-hydraulic proportional valve yog proportional electromagnet input voltage signal nyob rau hauv lub valve los tsim cov kev coj ua, thiaj li hais tias kev ua hauj lwm valve spool hloov chaw, valve chaw nres nkoj loj hloov thiab ua kom tiav lub siab thiab ntws tso zis Cheebtsam proportional rau lub input voltage. Spool tshem tawm tuaj yeem muab rov qab los ntawm mechanically, hydraulically lossis hluav taws xob. Electro-hydraulic proportional valve muaj ntau hom, yooj yim siv hluav taws xob thiab computer tswj ntawm ntau yam electro-hydraulic systems, siab tswj qhov tseeb, yooj ywm installation thiab siv, thiab muaj zog tiv thaiv kev ua qias tuaj, thiab lwm yam zoo, daim ntawv thov teb yog nthuav. . Fais fab proportional valve tsis siv neeg xaiv thiab sau, R & D thiab zus tau tej cov cartridge proportional valve thiab proportional multiway valve tag nrho xav txog cov yam ntxwv ntawm kev siv ntawm kev tsim machinery, nrog rau kev tswj, load sensing thiab siab them nqi zog. Nws yog ib qho tseem ceeb heev los txhim kho tag nrho cov txheej txheem ntawm mobile hydraulic machinery. Hauv particular, kev tswj hluav taws xob tswj kev ua haujlwm, kev tswj cov chaw taws teeb wireless thiab cov chaw taws teeb tswj kev ua haujlwm tau pom tias muaj kev cia siab rau daim ntawv thov. Lub hauv paus ntsiab lus: Cov teeb liab tawm tswv yim nce, cov khoom siv huab cua solenoid valve pilot valve 1 thim rov qab, thiab cov pa hluav taws xob solenoid pilot valve 7 nyob rau hauv lub xeev rov pib dua, tom qab ntawd cov cua nkag siab nkag mus rau hauv chav tsav 5 los ntawm SUP chaw nres nkoj los ntawm valve 1, lub siab. ntawm cov pilot chamber nce, cov roj siab ua rau sab sauv ntawm lub diaphragm 2, tom qab ntawd cov cua nkag valve core 4 txuas nrog lub diaphragm 2 yog qhib, lub tso pa valve core 3 kaw, thiab cov zis siab generated. Qhov tso zis siab no yog pub rov qab los tswj lub voj 8 los ntawm lub siab sensor 6. Ntawm no, kev sib piv ceev yog ua nrog tus nqi lub hom phiaj kom txog rau thaum cov zis siab yog proportional rau lub teeb liab input, uas ua rau muaj kev hloov pauv ntawm cov zis siab proportional rau qhov kev hloov hauv lub teeb liab input. Vim tias tsis muaj nozzle baffle mechanism, lub valve tsis rhiab rau impurities thiab muaj kev ntseeg siab.
