Axial flow pumps can be divided into two types according to the installation method, which can be divided into common seat type and block type. The motor and the transmission device are directly arranged on the pump structure, and the whole pump is shared with a foundation support; the split seat type pump is respectively arranged on the upper and the lower two different bases of the motor and the transmission device. The vertical axial flow pump is widely used in base structure, and a structure used only in some small axial flow pump.
中小型轴流泵通常做成叶片半调节式，叶片半调节式叶轮由键和螺母固定在轴的下端。当泵转子转动时，水被叶轮从喇叭形吸人管吸入，在叶片的推动下经带有轴流式导叶的导叶体和压出弯管排出泵外。转动系靠上导轴承和下导轴承进行径向支承，泵运转时由引水管引进洁净的润滑水供给上导轴承。
The medium and small sized axial flow pump is usually made into a half regulation type, and the blade is fixed on the lower end of the shaft by a key and a nut. When the pump rotor rotates, the water is from the horn shaped impeller suction tube with suction, axial guide vane diffuser and the pressure pipe discharged out of the pump in leaves under the impetus of. The rotation system is supported by the upper guide bearing and the lower guide bearing, and the pump is operated by a water diversion pipe and is introduced into the clean lubricating water supply.
分座立轴式轴流泵的泵壳重量由下面的安装基础承受，而电机与传动装置的重量、泵的轴向力则由上面的基础承受。电机需要安装在当地最高水位以上，泵的安装高度应保证叶轮处于最低水位之下，并有足够的淹没深度。当泵与电机之间的传动轴很长时，应在适当的位置加设中间导轴承，以防止轴的挠性过大而产生弯曲和振动。
The pump shell weight a vertical axial flow pump by the installed base below under axial force, and weight, pump motor and the transmission device is supported by the foundation of the above. Motor needs to be installed at the local maximum water level above, the pump installation height should ensure that the impeller is under the minimum water level, and there is sufficient depth of submerged. When the transmission shaft between the pump and the motor is very long, the middle guide bearing should be arranged in the proper position to prevent the bending and vibration of the shaft.
轴流泵也可采用全调节式，泵的尺寸通常都较大.
Axial flow pump can also be adjusted, the size of the pump is usually larger.
