Iindaba

Ehlabathini leevalve, i-servos, njengeteknoloji engathandekiyo, ikhokela ukuguqulwa kweshishini kunye neenzuzo zabo ezizodwa kunye namathuba angenamkhawulo. Namhlanje, makhe singene kule ntsimi yomlingo kwaye siphonononge indlela i-servos etshintsha ngayo ishishini levalvu kunye namathuba oshishino angenamkhawulo aqulethwe kuwo.

Yintoni i-servo?

I-Servo sisikhundla somqhubi we-servo, esiqhele ukusetyenziswa kulawulo lomphezulu we-rudder yemodeli yenqwelomoya kunye needrones. Ngophuhliso lwetekhnoloji kwiminyaka yakutshanje, ukusebenza kwe-servos kuye kwaphakama, kwaye ngokuthe ngcembe sele isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ezikumgangatho ophezulu ezinjengeerobhothi, izixhobo zonyango, kunye ne-automation ye-industrial. I-actuator yombane yevalve yombane ifana kakhulu ne-servo, zombini ezi ndawo kunye nohlengahlengiso lwe-angle. Xa kuthelekiswa ne-motor stepper, i-servo ine-torque enkulu, ukuchaneka okuphezulu, kwaye inokubonelela ngempendulo ye-angle kunye nokubonelela ngolwazi lwexesha lokwenyani.

Iinkalo zokusetyenziswa kweevalvu ze-servo

Phakathi kweentlobo ezininzi zeevalve, iivalve zombane zifumene ingqwalasela ebanzi kunye nezicelo ngenxa yokukwazi ukuzilawula, i-torque ephezulu, ukuchaneka okuphezulu kunye nokulawula kude. Phakathi kweevalve ezininzi zombane, kukho ezininzi iindidi ezigqwesileyo ezinokuthi ziqhutywe ngama-servos, phakathi kwazo ezona ziqhelekileyo ziyi-valve yebhola, i-butterfly valves kunye ne-reversing valves.

Ukusetyenziswa kwee-servos kwiivalvu zebhola zombane

Iivalve zebhola zisetyenziswa ngokubanzi kwibala lemizi-mveliso, kwaye eyona nto iphambili ilele ekomeleleni kwazo okugqwesileyo kunye nokusebenza kokutywinwa.

I-Torque iyisalathisi esibalulekileyo sokulinganisa ukusebenza kwee-valve zebhola, kwaye i-servo ineenzuzo ezicacileyo kulo mbandela. I-servo ine-torque enkulu kwaye inokugcina ukusebenza okuzinzile kwiindawo ezinzima. Akunjalo kuphela, ukuchaneka kunye nesantya sokuphendula se-servo zingcono kunezo ze-motor stepper, kwaye inokubonelela ngengxelo yexesha langempela kwi-angle, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lwendawo.

Ukusetyenziswa kwe-servo kwivalve yebhabhathane yombane

Iivalve ze-Butterfly nazo zisetyenziswa ngokubanzi kwintsimi yoshishino ngenxa yesakhiwo sazo esilula, ukusebenza okulula, ubunzima obulula kunye nobukhulu obuncinci.

Kwiivalve zebhabhathane, ulawulo oluchanekileyo oluphezulu kunye nokuphendula ngokukhawuleza kwe-servo kunokuphucula kakhulu ukuchaneka kokulawula ukuhamba kwevalve yebhabhathane. Kwangaxeshanye, inokuphinda iqonde ingxelo yomsebenzi ozimeleyo, ibone kwangexesha kwaye ilungise ukuphambuka kwe-engile, kwaye ineempawu zokudityaniswa okuqinileyo kunye nofakelo olufanelekileyo.

Ukusetyenziswa kwe-servo kwiivalvu zombane zokubuyisela umva

Iivalvu ezibonisa umkhomba-ndlela zincinci ngobungakanani kwaye ziphezulu ngamaza. Zihlala zisetyenziselwa ukunxibelelana, ukusika kunye nokubuyisela umva ukuhamba kweoli ye-hydraulic kunye nemibhobho yezonyango, kunye nokukhulula uxinzelelo kunye nokulawulwa kwezenzo ezilandelelanayo.

I-servo ayincinci kuphela ngobukhulu, kodwa ine-torque egqwesileyo kunye nokuchaneka phakathi kweeseva zobukhulu obufanayo. Iyakwazi nokulawulwa kuthotho kwaye usete indawo yayo engu-zero.

Ukongeza kwezi zivalo, i-servos inokufezekisa iziphumo ezilungileyo kwiindawo ezininzi. Kwimizila yokuvelisa i-automation automation, i-servos inokufezekisa ulawulo olukhawulezayo noluchanekileyo lweevalvu ukuphucula ukusebenza kakuhle kwemveliso; kwimimandla yepetroleum, imboni yeekhemikhali, unyango lwamanzi, njl., i-servos inokulawula ngokuchanekileyo ulwalathiso lokuhamba kunye nokuhamba kwamanzi ukuphucula ukhuseleko lwemveliso kunye nokuzinza; kunye nezixhobo zonyango, i-servos inokufezekisa ulawulo oluchanekileyo lwezixhobo zonyango kunye nokuphucula ukuchaneka kokuxilongwa kwezonyango kunye nonyango. Ukongeza, ii-servos zikwanawo amathemba osetyenziso olubanzi kwiindawo eziphakamileyo ezinje nge-aerospace, ukuveliswa kweemoto, kunye nokuhanjiswa kobuchule.

Ukuqukumbela

Ukusetyenziswa kwe-servo kwintsimi ye-valve ayitshintshanga kuphela indlela yokuqhuba i-valve, kodwa iphinde yaphucula ukuchaneka kokulawula i-valve kunye nokusebenza kakuhle. Kwimimandla ye-industrial automation, i-petrochemicals, izixhobo zonyango, njl., ukuvela kweevalve ze-servo ngokungathandabuzekiyo kuzise impumelelo engazange ibonwe ngaphambili kwishishini. Ngokuchaneka kwayo okuphezulu, i-torque ephezulu, impendulo ekhawulezayo kunye nezinye iimpawu, iivalve ze-servo zihlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza ezintsonkothileyo kwaye zifake ubutsha obutsha kuphuhliso loshishino lwevalvu yelizwe lam.
