Molao-motheo oa ho sebetsa

The reserved closing energy of heavy hamore hydraulic control butle closing check butterfly valve is heavy hamore potential energy, e arotsoeng ka hamore e boima ea automatic pressure e bolokang hydraulic control butle koalang hlahloba serurubele (eo ka mor'a moo e tsejoang e le khatello e boima ea hamore ho boloka mofuta) le ho notlela boima bo boima. Hamore khatello ea othomathiki e bolokang taolo ea haeteroliki butle-butle ho koala phunya serurubele (eo ka mor'a moo e bitsoang mofuta o boima oa ho notlela hamore). Maemo a ts'ebeletso a kenyelletsa haholo boemo ba pompo ea centrifugal, boemo ba pompo ea phallo ea axial le boemo ba turbine.

Boemo ba ho sebetsa ba pompo ea centrifugal e nang le ho buloa ha valve (ho kenyeletsoa pompo ea phallo e tsoakiloeng ea centrifugal): qala pompo pele, 'me u bule valve ka mor'a ho lieha nako e behiloeng.

Boemo ba ho sebetsa ba pompo ea phallo ea axial e bulehileng (ho kenyeletsoa le pompo ea phallo e tsoakiloeng ea axial): bula valve ka nako e le 'ngoe, kapa u bule valve ka lehlakoreng le itseng pele, ebe u qala pompo.

Boemo ba ho sebetsa ba turbine ea ho bula li-valve: bula pele valve ea bypass ho leka-lekanya khatello, ebe u bula valve, ebe u bula turbine.

Ka kakaretso ho hlokahala hore ho koaloe valve ka nako e le 'ngoe ea ho koala kapa ho felloa ke matla tlas'a maemo a sa tšoaneng a sebetsang.

Molao-motheo oa ts'ebetso ea electro-hydraulic ke o latelang:

Ha o bula valve, valve ea solenoid e khutlela morao, pompo ea oli ea qala, 'me oli ea hydraulic e kena ka har'a cylinder ea oli ka valve ea ho laola phallo le hose e nang le khatello e phahameng ho sututsa piston le ho khanna leqhubu le hokahaneng le eona ho phahamisa hamore e boima. bula valve. Ka mor'a hore valve e buloe sebakeng sa eona, tsamaiso ea ho boloka khatello e itekanetseng e qala; Enjene e tsoela pele ho tjhaja accumulator. Ha khatello e fihla sebakeng sa khatello e phahameng, pompo ea oli ea emisa. Nako ea ho bula li-valve e ka fetoloa ka ho potoloha letsoho la valve ea ho laola phallo, 'me sebaka sa phetoho ke 10 ~ 90 metsotsoana.
