Axial Flow Pumps have lower heads but higher flow rates and are extremely versatile in low lift areas. The axial Flow Pump is divided into three types: vertical, horizontal and inclined, and its basic structure is the same. The impeller is fixed to the lower end of the pump shaft. There are usually 4 to 5 blades on the impeller. The blades are available in fixed, semi-adjustable and fully adjustable versions. The latter two can adjust the mounting angle of the blades within a certain range for efficient operation. The blades are bolted to the hub, the base of the blade is engraved with a reference line, and the hub has several mounting angular positions. The adjustment method is as follows: first remove the impeller, loosen the bolts, mobilize the blades to align the reference line with the required angular position line, and then tighten the bolt. This adjustment method is called semi-adjusting. The full adjustment is achieved by a special adjustment mechanism to adjust the blade mounting angle. The role of the guiding impeller is to convert the kinetic energy of the rotary motion of the impeller outlet liquid into pressure energy to avoid the impact and vortex loss caused by the rotation of the liquid.
