REXROTH力士樂比例溢流閥工作原理
閱讀:1402 發(fā)布時(shí)間:2020-5-8REXROTH力士樂比例溢流閥比例溢流閥工作原理是:
比例溢流閥工作原理是:比例溢流閥通過彈簧力的大小改變溢流壓力大大小變化,比例電磁鐵作用在彈簧上的力可以按比例調(diào)整,所以就輸入信號(hào)變化比例溢流閥的壓力也會(huì)變化。
普通溢流閥與比例溢流閥一樣,都有一個(gè)閥芯,閥芯的一端是液壓油產(chǎn)生的壓力,另一端是機(jī)械力。普通溢流閥通過調(diào)節(jié)彈簧力,來調(diào)整液壓壓力。而比例溢流閥是電磁鐵直接產(chǎn)生推力,作用在閥芯上,電磁鐵上的輸入電壓可以在0-24伏之間變化,產(chǎn)生的推力就隨之變化,從而得到連續(xù)變化的液壓壓力。
因?yàn)楸壤姶盆F的推力不大,所以直動(dòng)式比例溢流閥的流量很小,壓力70兆帕?xí)r,流量只有1升/分鐘左右。需要大流量比例閥的時(shí)候,要把這個(gè)比例閥做先導(dǎo)閥,還要配一個(gè)大通徑的溢流閥。
