Ukuseta iiparamitha ezisisiseko zesixhobo sombane sevalve
I-valve yombane wokwenza umbane
Isixhobo sombane seValve sisixhobo sokuqhuba esiyimfuneko ukuqonda ulawulo lwenkqubo olukude, ulawulo oluzenzekelayo kunye nolawulo olukude lwevalve. Inkqubo yayo yokunyakaza inokulawulwa ngokubetha, i-torque okanye i-axial thrust. Ngenxa yokuba iimpawu zokusebenza kunye nokusetyenziswa kwevalve yesixhobo sombane kuxhomekeke kuhlobo lwesivalo, iinkcukacha zesixhobo esisebenzayo kunye nendawo yevalve kumbhobho okanye isixhobo.
Isixhobo sombane sibandakanya la malungu alandelayo:
** Injini ibonakaliswe kumthamo owomeleleyo wokugcwala, i-torque enkulu yokuqala, umzuzu omncinci we-inertia, ixesha elifutshane, umsebenzi ophakathi.
Indlela yokunciphisa yokunciphisa isantya semveliso yemoto.
Indlela yokulawula i-stroke ukulungisa nokulawula ngokuchanekileyo indawo yokuvula kunye nokuvala i-valve.
Indlela yokunciphisa iTorque yokulungelelanisa itorque (okanye ukutyhala) kwixabiso elimiselweyo.
Umatshini wokutshintsha okwenziwa ngesandla kunye nombane, indlela yokudityaniswa kwesixhobo sokusebenza ngesandla okanye sombane.
Isalathisi sokuvula sibonisa indawo yevalve ngexesha lokuvula nokuvala.
Okokuqala, khetha i-actuator yombane ngokohlobo lwevalve
1. I-Angle stroke actuator yombane (i-Angle 360 degrees) ifanelekile kwi-valve butterfly, i-valve yebhola, i-valve yeplagi, njl.
Ukujikeleza kwe-shaft ephumayo ye-actuator yombane ingaphantsi kweveki enye, oko kukuthi, ngaphantsi kwe-360 degrees, ngokuqhelekileyo i-90 degrees ukuqonda ukuvuleka kwevalve kunye nokulawula inkqubo yokuvala. Olu hlobo lwe-actuator yombane lwahlulwe lwaba ludidi loqhagamshelo oluthe ngqo kunye nohlobo lwesiseko secrank ngokwendlela yojongano lofakelo olwahlukileyo.
A) Iqhagamshelwe ngokuthe ngqo: ibhekisa kuhlobo lofakelo oludityanisiweyo ngokuthe ngqo lweshafti ephumayo ye-actuator yombane kunye nesiqu sevalve.
B) Uhlobo lwe-Base crank: ibhekisa kuhlobo apho i-shaft ephumayo idityaniswe nesiqu sevalvu ngekranki.
2. I-multi-rotary actuator yombane (i-Angle 360 degrees) ifanelekile kwi-valve yesango, i-globe valves, njl.
Ukujikeleza kwe-shaft ephumayo ye-actuator yombane inkulu kuneveki enye, oko kukuthi, inkulu kune-360 degrees. Ngokuqhelekileyo idinga ngaphezulu kwesangqa esinye ukuqonda inkqubo yokuvula nokuvala inkqubo yevalve.
3. I-stroke echanekileyo (intshukumo ethe ngqo) ifanelekile kwi-valve yokulawula isihlalo esisodwa, i-valve yokulawula izihlalo ezimbini, njl.
Intshukumo yeshaft ephumayo ye actuator yombane kukushukuma komgca, hayi ukujikeleza.
Ezimbini, ngokweemfuno zolawulo lwenkqubo yokuvelisa ukumisela indlela yokulawula i-activator yombane
1. Uhlobo lokutshintsha (vula ulawulo lweluphu)
Ukutshintsha ii-actuator zombane ngokubanzi ziqonda ulawulo lwevalvu evuliwe okanye evaliweyo. Ivalve ikwimo evuleke ngokupheleleyo okanye ikwindawo evalwe ngokupheleleyo. Olu hlobo lwesivalo aludingi ukulawula ngokuchanekileyo ukuhamba okuphakathi.
Kubaluleke kakhulu ukukhankanya ukuba ukutshintsha i-actuator zombane nako kunokwahlulahlula kwisakhiwo esahlukileyo kunye nesakhiwo esidibeneyo ngenxa yeefom ezahlukeneyo zesakhiwo. Oku kufuneka kucaciswe xa ukhetha uhlobo, kungenjalo kudla ukwenzeka kwintsimi yofakelo kunye nesixokelelwano solawulo *** kunye nokunye ukungalingani.
A) Isakhiwo sokwahlula (ngokuqhelekileyo sibizwa ngokuba luhlobo oluqhelekileyo) : iyunithi yokulawula ihlukaniswe kwi-actuator yombane. I-actuator yombane ayikwazi ukulawula i-valve ngokuzimeleyo, kodwa kufuneka ilawulwe yiyunithi yokulawula yangaphandle. Ngokuqhelekileyo, umlawuli wangaphandle okanye ikhabhinethi yokulawula isetyenziselwa ukuxhasa.
Ukungalungi kwesi sakhiwo kukuba ayilungele ukufakwa ngokubanzi kwenkqubo, ukunyuka kweengcingo kunye neendleko zokufakela, kunye nokuthanda ukusilela, xa ukusilela kusenzeka, ayilungele ukuxilongwa kunye nokugcinwa kwayo, indleko-esebenzayo ayifanelekanga. .
B) Isakhiwo esidibeneyo (esiqhelekileyo sibizwa ngokuba luhlobo oludibeneyo) : iyunithi yokulawula kunye ne-actuator yombane zipakishwe ngokupheleleyo, ezinokuthi ziqhutywe kwindawo ngaphandle kweyunithi yokulawula yangaphandle, kwaye inokusebenza ngokude kuphela ngokukhupha ulwazi olufanelekileyo lolawulo.
Iingenelo zesi sakhiwo yinkqubo efanelekileyo yokufakela ngokubanzi, ukunciphisa i-wiring kunye neendleko zokufakela, ukuxilongwa lula kunye nokuxazulula iingxaki. Nangona kunjalo, iimveliso zendalo ezidityanisiweyo zesakhiwo nazo zineziphene ezininzi, ngoko ke i-activator yombane ekrelekrele iveliswa.
2. Uhlobo olulungisekayo (ulawulo oluvaliweyo lwelophu)
I-actuator yombane elawulayo ayinayo kuphela umsebenzi wokutshintsha uhlobo oludibeneyo lwesakhiwo, kodwa inokulawula ngokuchanekileyo i-valve kunye nokulungelelanisa ukuhamba okuphakathi.
A) Uhlobo lophawu lolawulo (olukhoyo, amandla ombane)
Umqondiso wolawulo lwe-actuator yombane elawulayo ngokubanzi inesignali yangoku (4 ~ 20mA, 0 ~ 10mA) okanye isignali yombane (0 ~ 5V, 1 ~ 5V). Uhlobo kunye neeparitha zomqondiso wolawulo kufuneka zicace xa ukhetha uhlobo.
B) Ifomu yokusebenza (umbane kuhlobo, uhlobo olucinyiweyo lombane)
Imowudi yokusebenza ye-actuator yombane elawulayo luhlobo oluvulekileyo lombane ngokubanzi (uthatha ulawulo lwe-4 ~ 20mA njengomzekelo, uhlobo oluvulekileyo lombane lubhekisa kumqondiso ohambelana ne-4mA yivalve evaliweyo, ivalve ehambelana ne-20mA evulekileyo), kunye nezinye. luhlobo olusondeleyo lombane (ukuthatha ulawulo lwe-4-20MA njengomzekelo, uhlobo oluvulekileyo lombane lubhekiselele kwisignali ehambelanayo ye-4mA yi-valve evulekileyo, i-valve ye-20mA ehambelanayo vala). I-electrode ekwaziyo ukunxiba
C) ilahleko yokhuseleko lomqondiso
Ukulahlekelwa kokhuseleko lomqondiso kubhekiselele ekulahlekelweni kwesignali yokulawula ngenxa yeempazamo zomgca, i-actuator yombane iya kulawula i-valve evulekile kwaye isondele kwixabiso elimiselweyo lokukhusela, ixabiso eliqhelekileyo lokukhusela livulekile ngokupheleleyo, livalwe ngokupheleleyo, ligcine kwiimeko ezintathu.
Eyesithathu, ngokokusetyenziswa kokusingqongileyo kunye nokuhlelwa komgangatho wokuqhuma kwezixhobo zombane
Ngokweemfuno zendawo yokusetyenziswa kunye nebakala lobungqina bokuqhuma, isixhobo sombane sevalve sinokwahlulwa sibe luhlobo oluqhelekileyo, uhlobo lwangaphandle, uhlobo lwe-flameproof, uhlobo lwangaphandle lwe-flameproof.
Qinisekisa i-torque yokuphuma ye-actuator yombane ngokwetorque efunwa yivalve
Ukuvulwa kwevalve kunye nokuvala itorque efunekayo imisela itorque yemveliso ye actuator yombane ukukhetha indlela, ngokubanzi ibekwe phambili ngumsebenzisi okanye ngokuthelekisa umenzi wevalvu, njengoko umenzi we-actuator unoxanduva lwe torque yemveliso ye actuators, ukuvulwa kwevalve yesiqhelo kunye nokuvala. i-torque efunekayo igqitywa ngubungakanani be-valve ye-diameter kunye noxinzelelo lokusebenza, kodwa ngenxa yokuchaneka komenzi wevalve, inkqubo yokuhlanganisana, ngoko ke, i-torque efunwa yimilinganiselo efanayo yeevalvu eziveliswe ngabavelisi abahlukeneyo nayo yahlukile, nangona iinkcukacha ezifanayo zeevalvu eziveliswe ngumenzi wevalvu efanayo. Xa i-actuator ikhethiwe, ukhetho lwe-torque luncinci kakhulu ukuba lubangele ukuvulwa okuqhelekileyo kunye nokuvalwa kwe-valve, ngoko i-actuator yombane kufuneka ikhethe uluhlu olufanelekileyo lwe-torque.
Okwesine, ukhetho oluchanekileyo lwesiseko sesixhobo sombane sevalve:
I-torque yokusebenza: i-torque esebenzayo iyona parameter ephambili yesixhobo sombane sevalve, i-torque ephumayo yesixhobo sombane kufuneka ibe yi-1.2 ~ 1.5 amaxesha obuninzi be-torque yokusebenza kwevalve.
I-Operation thrust: kukho izinto ezimbini eziphambili zesixhobo sombane sevalve: enye ayixhotyiswanga ngepleyiti yokutyhala, itorque ephuma ngokuthe ngqo; Enye ixhotyiswe nge-thrust disc, i-torque yemveliso ngokusebenzisa i-thrust disc stem nut iguqulelwe kwi-output thrust.
