Umthethonqubo kanye nomgomo wesilinganiso sokuthekelisa sempahla ye-valve kagesi sikhuphuka unyaka nonyaka

I-valve kagesi isetshenziswa kakhulu ekulungiseni ukugeleza okuphelele kwepayipi lesofthiwe yohlelo lomoya oluwuketshezi kanye nomusi. Isakhiwo se-valve kagesi singahlukaniswa sibe izingxenye ezimbili, ingxenye engenhla ihlukaniswe i-actuator kagesi, ingxenye engezansi ihlukaniswe i-valve.
Ukusebenza kwangempela kwe-actuator kagesi ukulawula ukuma kwe-valve, ukuqedela ukuvulwa nokuvala i-valve, bese ubona izinto ezibonakalayo ekushintsheni kwamandla epayipi noma ukulungiswa. I-actuator kagesi ye-valve kagesi ngokuvamile yakhiwe nge-asynchronous motor enezigaba ezintathu, i-transmission gear reducer, inhlangano enciphisa ibanga, uhlobo lwezandla kanye nenhlangano yokuguqula okuzenzakalelayo, inkomba yokuvula kanye nezingxenye zikagesi. Amandla okukhipha i-valve motor ngokuvamile angu-0.37 ~ 5.5kW.
Ukuze kuqinisekiswe ukushintshwa kwamandla okuthembekile kwe-valve kagesi, ukuvikelwa kwe-over-voltage kulawulwa ngokuqinile. Izinyathelo zokuvikela ezijwayelekile uhlobo lwempahla kagesi kanye nohlobo lwe-pedal. I-DL yamanje edluliselwe isetshenziswa njengesivikelo se-overvoltage yokulungiswa kwemishini kagesi. Ukulungiswa kwe-Pedal kusebenzisa umkhawulo wegiya ukuvikela i-over-voltage.
1. Imithetho yokulawula
Ukulawulwa kwe-valve kagesi: cindezela inkinobho ye-valve evulekile, i-valve ivuliwe, cindezela inkinobho ye-valve yokuvala, i-valve ivaliwe. Uma i-valve ivuleke ngokugcwele noma ivaliwe, inhlangano yokulawula ukuhlelwa kwe-stroke izonqamula ngokuzenzakalelayo isifunda sokulawula i-ac contactor, futhi ukufinyelela i-valve kuvuleke ngokugcwele noma kuvaliwe ukukhanya kwenkomba yesignali. I-relay yamanje yohlobo lwe-DL isetshenziselwa ukulungiswa lapho isekethe yamandla ivinjiwe futhi ilayishwa ngokweqile ohlelweni lokuvula noma lokuvala. Kukhona ukuxhuma kagesi phakathi kwe-valve ac contactor evulekile kanye nesixhumi esiseduze sevalvu.
Kukhona futhi umzila osebenza nge-pedal one-double overtorque yokugcinwa kwe-overtorque kanye nemishini yokuqapha ukuvulwa kwamavalvu.
2. Umgomo we
Xhuma i-switch power supply, isibani senkomba sivuliwe.
