You need to understand the situation and attention of the installation of the axial flow pump , the following electromechanical is more important
(1) Adjust the installation angle of the blades on the impeller parts according to the use conditions, so that the installation angles of the blades are consistent, and there must be no looseness.
(2) Use a spirit level to correct the level of the pump base, tighten the anchor bolts, and fill the anchor bolt holes with concrete. After the solidification, check the level again.
(3) The pump shaft and the transmission shaft must be installed on the same plumb line, and the tolerance is less than 0.04mm / m. Make leaves
The gap between the outer circle and the casing of the impeller chamber is uniform along the circumference.
(4) After installation, check whether the nuts of each coupling and each foot bolt are tightened. When tightening the nuts on the drive shaft and the pump shaft, pay attention to the direction of thread rotation. Axial flow pumps require large power at low flow rates, so they should be started with the valve fully open, and not with the valve closed.
Preparation before installation:
(1) Check the pump body, transmission device and motor for damage. If the pump shaft and transmission shaft are bent, they must be straightened.
(2) Tools and lifting appliances should be complete.
(3) Refer to the external dimensions of the installation and check the pump foundation and the water inlet pipeline, so that the distance between the centerline of the pump impeller and the lowest water surface meets the requirements of the cavitation margin.
(4) Because the structure of the inlet pool and the arrangement of several pumps in the same inlet pool have a great impact on the working performance of the pump, there are many places to pay attention to, so this situation must be understood
