雙作用葉片泵的工作原理
它的作用原理和單作用葉片泵相似,不同之處只在于定子表面是由兩段長半徑圓弧、兩段短半徑圓弧和四段過渡曲線八個部分組成,且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時針方向旋轉(zhuǎn)的情況下,密封工作腔的容積在左上角和右下角處逐漸增大,為吸油區(qū),在左下角和右上角處逐漸減小,為壓油區(qū);吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn),每個密封工作腔完成吸油和壓油動作各兩次,所以稱為雙作用葉片泵。泵的兩個吸油區(qū)和兩個壓油區(qū)是徑向?qū)ΨQ的,作用在轉(zhuǎn)子上的液壓力徑向平衡,所以又稱為平衡式葉片泵。
雙作用葉片泵的瞬時流量是脈動的,當葉片數(shù)為4的倍數(shù)時脈動率小。為此,雙作用葉片泵的葉片數(shù)一般都取12或16。
