Maziko kusankha gulugufe valavu magetsi actuator

A. Torque yogwira ntchito

Ma torque ogwiritsira ntchito ndiye gawo lofunikira kwambiri pakusankhavalavu ya butterflychoyatsira magetsi. Makokedwe otulutsa a actuator yamagetsi ayenera kukhala 1.2 ~ 1.5 nthawi yayitali kwambiri yogwiritsira ntchitovalavu ya butterfly.

B. Kukankhira ntchito

Pali zigawo ziwiri zazikulu zavalavu ya butterfly choyatsira magetsi: imodzi ilibe mbale yothamangitsira, ndipo torque imatuluka mwachindunji; ina ili ndi mbale yoponyera, ndipo torque yotulutsa imasinthidwa kukhala choponderetsa kudzera mu nati ya valavu yomwe ili mu thrust plate.

C. Chiwerengero cha matembenuzidwe a shaft yotulutsa

Chiwerengero cha matembenuzidwe a shaft yotulutsa ya valavu yamagetsi yamagetsi imagwirizana ndi m'mimba mwake mwadzina la valavu, kukwera kwa tsinde la valve, ndi kuchuluka kwa mitu yolumikizidwa. Iyenera kuwerengedwa molingana ndi M=H/ZS (M ndi chiwerengero chonse cha matembenuzidwe omwe chipangizo chamagetsi chiyenera kukumana nacho, ndipo H ndi kutalika kwa Valve kutsegula, S ndi phula la ulusi wa valve stem drive, Z ndi nambala ya mitu ya ulusi wa tsinde).

D. Kutalika kwa tsinde

Kwa ma valve a tsinde ozungulira maulendo angapo, ngati kutalika kwa tsinde komwe kumaloledwa ndi chowongolera magetsi sikungadutse tsinde la valavu yokhala ndi zida, sikungasonkhanitsidwe mu valavu yamagetsi. Choncho, m'mimba mwake mkati mwa dzenje lotulutsa shaft la chipangizo chamagetsi chiyenera kukhala chokulirapo kusiyana ndi kunja kwa tsinde la valve ya valavu yotuluka. Kwa ma valve otembenukira pang'onopang'ono ndi ma valve a tsinde lakuda mu mavavu otembenuka ambiri, ngakhale palibe chifukwa choganizira momwe tsinde la valavu likudutsa, kutalika kwa tsinde la valve ndi kukula kwa keyway ziyenera kuganiziridwanso mokwanira. posankha, kotero kuti valavu ikhoza kugwira ntchito bwino pambuyo pa msonkhano.

E. Linanena bungwe liwiro

Ngati kutsegula ndi kutseka kwa valve ya butterfly kuli mofulumira kwambiri, n'zosavuta kupanga nyundo yamadzi. Choncho, liwiro loyenera lotsegula ndi kutseka liyenera kusankhidwa malinga ndi zochitika zosiyanasiyana zogwiritsira ntchito.
