双吸离心泵的结构及其机械密封的设计 摘要：离心泵在工业和农业各部分使用非常广泛，双吸单级泵实际上等于将两个相同的叶轮背靠背地装在一根轴上并联地工作这种泵流量大能自动平衡轴向力。双吸单级泵一般采用半螺旋形吸入室。从电机的选择计算、轴的选择计算、叶轮的尺寸以及水泵的外形尺寸的确定,基本上解决了泵的大体结构,在其它部件中,连接法兰、叶轮螺母等都是根据具体位置来计算设计的，根据泵工作的环境和轴经的大小选择机械密封以满足工作要求。关键词 油泵 密封 结构设计Abstract: Centrifugal pumps in various parts of industry and agriculture is widely used single-stage double-suction pumps in fact equivalent to two of the same impeller mounted back to back to work in a parallel axis that can automatically balance traffic flow pump axial force. Single-stage double-suction pumps generally use the semi-spiral suction chamber. Calculated from the motor of choice, the choice of axis calculations, the pump impeller size and shape to determine the size, basically to solve the general structure of the pump, in other parts, the connection flange, impeller nuts are all calculated based on specific location designed to work under the pump shaft by the size of the environment and select mechanical seal to me
