DAIKIN 雙聯(lián)定量葉片泵/日本DAIKIN銷售處/*日本大金
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?！?RP08A1-07-30,、RP08A2-07-30,、RP08A2-07-30RC、RP15A1-15-30,、RP15A2-15-30,、RP15A3-15-30、RP15A1-22-30,、RP15A2-22-30,、RP15A3-22-30、RP15A1-15-30RC,、RP15A2-22-30RC,、RP15C11H-15-30、RP15C12H-15-30,、RP15C13H-15-30,、RP15C22H-15-30、RP15C23H-15-30,、RP15C11H-22-30,、RP15C12H-22-30、RP15C13H-22-30,、RP15C22H-22-30,、RP15C23H-22-30、RP15C11JA-15-30,、RP15C12JA-15-30,、RP15C13JA-15-30、RP15C22JA-15-30,、RP15C23JA-15-30,、RP15C11JB-15-30、RP15C12JB-15-30,、RP15C13JB-15-30,、RP15C22JB-15-30、RP15C23JB-15-30,、RP15C11JP-15-30,、RP15C12JP-15-30、RP15C13JP-15-30,、RP15C22JP-15-30,、RP15C23JP-15-30、RP23A1-22-30,、RP23A2-22-30,、RP23A3-22-30、RP23A1-37-30、RP23A2-37-30,、RP23A3-37-30,、RP23A2-22-30RC、RP23A3-37-30RC,、RP23C11H-22-30,、RP23C12H-22-30、RP23C13H-22-30,、RP23C22H-22-30,、RP23C23H-22-30、RP23C11H-37-30,、RP23C12H-37-30,、RP23C13H-37-30、
