Pua pua ntawm li qub yog siv los tswj txhua yam ntawm nws txoj haujlwm hauv ib lub tuam txhab fais fab. Ntau thiab ntau li qub nrog tswj actuator yog siv rau thaj tsam loj. Dab tsi' ntau dua, valve thiab actuator yuav tsum tau ua haujlwm ntawm kev kub siab, kub raws li lub zog cog raug yuam kom xav tau ntxiv.
Tam sim no cia peb tham ib yam dab tsi txog xaiv actuator.Tsis muaj teeb meem rau pneumatic actuator lossis hluav taws xob actuator, peb yuav tsum tau txais lub zog ntawm lub valve thiab tom qab ntawd hom nruab nrab. Yog hais tias qhov nruab nrab yog chav los yog tsis-lubricated nruab nrab, 25% kev ruaj ntseg tus nqi yuav tsum tau ntxiv rau torque; Yog hais tias qhov nruab nrab tsis yog-lubricated nruab nrab, 60% kev ruaj ntseg tus nqi yuav tsum tau ntxiv; 100% kev ruaj ntseg valve yuav tsum tau ntxiv thaum nruab nrab yog tsis-lubricated media kis tau tus mob hmoov.
Rau kev xaiv pneumatic actuator, muaj singe nkaus pneumatic thiab ob chav ua haujlwm pneumatic. Kawm rau hauv huab cua muab siab thiab xyuas lub rooj torque ntawm ib leeg ua yeeb yam thiab ob chav ua yeeb yam, thaum kawg xaiv cov pneumatic actuator tsim nyog.
Qhov tseeb actuator nrog valve coj kev nyab xeeb kev khiav hauj lwm thiab lub neej ntev lub sij hawm.Lub sij hawm mounted li qub nrog actuator, qhov zoo tshaj plaws postion yog actuator center aaxis thiab valve qia coaxial.
Tom qab sib sau ua ke, actuator thiab valve yuav tsum tau sim ua ke. Lub valve yog kev sib hloov du, tsis muaj nres thiab nkag mus thaum lub valve tau rov qhib thiab kaw.
