液壓系統(tǒng)壓力繼電器使用方法
壓力繼電器在液壓系統(tǒng)中的應(yīng)用非常廣泛。如:當(dāng)機床切削力過大時自動退刀、潤滑系統(tǒng)因堵塞發(fā)生故障時自動停車等都是由壓力繼電器發(fā)出電信號來控制的。壓力繼電器的應(yīng)用例子不勝枚舉,但歸納起來,都是起自動順序控制和安全保護兩種作用。舉2個例子跟大家說下壓力繼電器的使用。
(1)壓力繼電器起順序控制作用 圖1所示爲一種利用壓力繼電器控制電磁換向閥以實現(xiàn)油缸順序動作的回路,首先1YA通電,閥1換向,壓力油進入缸5使其活塞右移。當(dāng)?shù)竭_終點后,系統(tǒng)壓力升高。壓力繼電器3發(fā)出電信號使3YA通電,壓力油進入缸6的左腔使其活塞前進,前進到終點后,電路設(shè)計使4YA通電(3YA斷電)。閥2換向,壓力油進入缸6右腔,使其活塞返回。當(dāng)活塞返回至原位時,系統(tǒng)壓力升高,壓力繼電器4發(fā)出信號,使2YA通電(1YA斷電).壓力油進入缸5的右腔,使其活塞返回。爲了防止壓力繼電器誤動作,壓力繼電器的預(yù)調(diào)壓力應(yīng)比油缸的工作壓力高300~500KPa,但比溢流閥的調(diào)定壓力低300-500KPa。
(2)壓力繼電器起安全保護作用 圖2爲壓力繼電器用于安全保護作用的一種回路,壓力繼電器裝在油缸的進油腔。當(dāng)油缸前進碰上擋鐵或切削力過大時,缸的進油腔(左端)壓力升高,達到壓力繼電器的調(diào)定值時,壓力繼電器發(fā)出電信號使電磁閥2斷電,油缸快速返回。
