    Abstract: A volute for a pump featuring a volute or casing having a pump inlet for receiving a fluid being pumped, a pump discharge for providing the fluid, and a volute or casing vane forming double volutes therein. The volute has an upper cutwater farthest from the pump discharge defining an upper cutwater throat area and an end of passage for the upper cutwater, and also has a lower cutwater closest to the pump discharge defining a lower cutwater throat and a corresponding end of passage for the lower cutwater. The upper cutwater throat area is dimensioned to be greater than and not equal to the lower cutwater throat area so the upper cutwater throat area and the lower cutwater throat area provide substantially equal flow velocity at both the upper cutwater and the lower cutwater in response to an angular sweep of the fluid being pumped. The end of passage for the upper cutwater is dimensioned with an upper cutwater passage area that is greater than and not equal to a corresponding lower cutwater passage area of the corresponding end of passage for the lower cutwater so that upper and lower cutwater passage areas at the pump discharge are balanced as a function of differing rates of flow of the fluid being pumped therein and so that the fluid being pumped from associated ends of the upper and lower cutwater passage areas meets at the pump discharge with a substantially equal velocity.

    Abstract translation: 用于具有蜗壳或套管的泵的蜗壳具有用于接收被泵送的流体的泵入口,用于提供流体的泵排出口以及在其中形成双重蜗壳的蜗壳或套管叶片。 蜗壳具有距离泵排出口最远的上部切割水,其限定上切割水喉区域和用于上部切割水的通道的端部,并且还具有最靠近泵排出口的下部切割水,其限定下部切割水喉部和相应的通道末端 较低的切割水。 上切割喉咙区域的尺寸设定为大于并不等于较低的切割水喉部区域,因此上切割水喉区域和下切割喉咙区域响应于上切割水和下切割水道而提供基本上相等的流速 正在泵送的流体的角度扫掠。 上部切割水的通道的末端的尺寸设置有较大的切割水通道面积,该上部通道面积大于并且不等于下部切割水的相应的通道末端的相应较低的切割水通道面积,从而使得上部和下部切割水通道区域 泵排出作为泵送的流体的不同流量的函数来平衡,并且使得从上和下切水通道区域的相关端泵送的流体以基本上相等的速度在泵排出口相交。
