Introduction to the basic structure of axial flow pump :

The basic components of an axial flow pump are composed of a suction tube impeller (including blades and hubs), a guide vane, a pump shaft, a water outlet elbow, upper and lower bearings, a stuffing box, and a blade angle adjustment mechanism.

(1) Suction tube: In order to improve the hydraulic conditions at the entrance, a streamlined horn tube or a flow channel is often used.

(2) Impeller: It is the main working part of the axial flow pump, and its performance directly affects the performance of the pump. The impeller can be divided into three types: fixed type, semi-adjustable type and full-adjustment type according to the possibility of adjustment. The fixed axial flow pump is a one-piece blade and hub body, and the installation angle of the blade cannot be adjusted. The blades of the semi-adjustable axial flow pump are bolted to the hub body with nuts, the reference line is engraved on the root of the blade, and the position line of the corresponding installation angle is engraved on the hub body. Its performance curve will be different. According to the requirements of use, the blade can be installed in a certain position. During the use process, if the operating conditions change and adjustment is needed, the impeller can be removed, the nut can be loosened and the blade can be rotated to align the reference line of the blade with the hub A certain angle line on the body is required, then the nut is tightened, and the impeller can be installed. A full-adjustable axial flow pump is a pump that can change the installation angle of the blade through a set of oil pressure adjustment mechanisms when the machine is stopped or not stopped according to different head and flow requirements. To meet the requirements of use, this fully-adjustable axial flow pump adjustment mechanism is relatively complicated and is generally used in large axial flow pump stations.

Axial flow pump startup considerations

1. Start the oil pump. Note whether the steering of the pump shaft is correct.

2. Pay attention to the readings of the pressure gauge and vacuum gauge. After starting, when the readings of the pressure gauge and vacuum gauge are stable after a period of time fluctuation, it means that the pump has been filled with liquid, and the oil pump is pumped into the normal oil transfer operation.

3. Pay attention to abnormal sounds and vibrations during rotation.
