| 单级离心泵包括泵体，泵盖，带输出轴的电动机，在泵体内装设的泵轴、轴承座、叶轮、机械密封和机封压盖，其特征在于，它还包括位于电动机输出轴与泵轴之间设置的对夹式联轴器，以及安装在轴承座上的以辅助支承泵轴的导轴承;所述对夹式联轴器分别与电动机输出轴和泵轴刚性连接，在电动机输出轴与泵轴之间留有便于机械密封和机封压盖装拆的空间距离。在维修或更换机械密封时，无须拆卸电动机及泵盖。 The single-stage centrifugal pump comprises a pump body, a pump cover, a motor with an output shaft, a pump shaft, a bearing seat, an impeller, a mechanical seal and a mechanical seal gland arranged in the pump body, which is characterized in that it also comprises a wafer type coupling arranged between the output shaft of the motor and the pump shaft, and a guide bearing arranged on the bearing seat to assist in supporting the pump shaft; the wafer type coupling is respectively electrically driven The output shaft of the machine is rigidly connected with the pump shaft, and there is a space distance between the output shaft of the motor and the pump shaft that is convenient for the installation and disassembly of the mechanical seal and the mechanical seal gland. It is not necessary to dismantle the motor and pump cover when repairing or replacing the mechanical seal. |
