Abstract

The invention discloses an axial flow pump for sewage treatment equipment. The equipment comprises a shell. A square frame is fixedly connected to the top of the shell. An adjusting mechanism is installed above a thick rod. The adjusting mechanism comprises curved rods, a sleeve plate, notches, inserting rods, a long rod, a wide plate and guide vanes, wherein the inner sides of the two curved rodsare connected with the upper portions of the left side and the right side of the thick rod in an inserted manner correspondingly. The long rod is controlled by the adjusting mechanism to move upwardsand downwards to drive the guide vanes to change the positions, space change is achieved, it is avoided that a large number of bubbles are generated, cavitation damage is reduced, and the service life is prolonged; because the space between the guide vanes and blades is adjusted through the adjusting mechanism, flow guiding speed control is achieved, flow dividing treatment at a water outlet is facilitated, the working difficulty is reduced, the stability is improved. rotation friction is reduced, looseness is prevented, normal use is guaranteed, and the working efficiency is guaranteed; andwhen the height of a vertical plate is adjusted through the control mechanism, a curved block meets the requirement for fixing at different positions, limitation is eliminated, practicability is improved, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of axial flow pumps for sewage treatment equipment, in particular to an axial flow pump for sewage treatment equipment. Background technique [0002] Axial flow pumps rely on the force generated by the blades of the rotating impeller on the liquid to transport the liquid along the axial direction. There are several types of vertical, horizontal, inclined and through-flow pumps. [0003] When the existing axial flow pump for sewage treatment equipment is used, the distance between the guide vanes and the blades moves when the flow rate is large. Due to the close distance, a large number of air bubbles will be generated, the cavitation is serious, it is easy to be damaged, and the service life is shortened, and the distance is relatively close. The diversion speed is fast, which is not convenient for the diversion treatment of the discharge port, which increases the work, and the power output end is directly c...
