HAWE哈威調(diào)速閥,HAWE調(diào)速閥它由定差減壓閥,,液動換向閥和簡式節(jié)流閥三部分組成,。油缸停歇后,減壓閥處于全開狀態(tài),,而液動換向閥處于關(guān)閉狀態(tài),。再次啟動時,液壓油必須首先打開液動換向閥,,同時由于減壓閥彈簧腔油壓很低,,減壓閥被抬起,閥口被關(guān)小,,通過的流量很小,。當(dāng)油缸油壓建立起來后,維持一個適當(dāng)?shù)拈_口,,與后面的節(jié)流閥一起起調(diào)速作用,。因此不會出現(xiàn)前沖現(xiàn)象。
新型調(diào)速閥的原理及應(yīng)用
它由定差減壓閥,、電磁換向閥和兩個簡式節(jié)流閥組成,。當(dāng)換向閥上位接通時,通過的流量由閥調(diào)節(jié),,當(dāng)換向閥下位接通時,,通過的流量由閥調(diào)節(jié)。
兩種工進速度可以單獨調(diào)節(jié),,由一種工進轉(zhuǎn)入另一種工進時,,由于減壓閥一直處于減壓狀態(tài),油缸不會出現(xiàn)前沖現(xiàn)象,。而且該回路的速度調(diào)節(jié)靈活方便,。回路發(fā)熱少,,效率高,。
HAWE哈威調(diào)速閥,,HAWE調(diào)速閥型調(diào)速閥在結(jié)構(gòu)上是由兩個節(jié)流閥共用一個定差減壓閥,在定差減壓閥與兩個節(jié)流閥之間嵌入換向閥,,與原先用兩個調(diào)速閥與一個換向閥組成的速度換接回路相比,,大大縮小了占用的空間,還簡化了回路,。調(diào)速性能與普通調(diào)速閥相同,,而速度換接性能卻顯著提高。這種新型調(diào)速閥尤其適用于液壓系統(tǒng)集成塊尺寸受限制的場合,。
新型調(diào)速閥和新型調(diào)速閥,,克服了以前調(diào)速閥節(jié)流調(diào)速回路及工進速度換接回路中的不足,在液壓機床上有廣闊的發(fā)展前景 HAWE哈威調(diào)速閥,,HAWE調(diào)速閥
