Problems solved by technology

In this way, not only the experimental cost is high, but also the friction force of the fixed pulley is introduced, and the measurement accuracy is low
[0004] In addition, the existing technology can only measure the thrust of the submersible mixer, but cannot measure the influence of the torque and placement angle of the agitator on the flow field, nor can it accurately control the speed regulation of the submersible mixer

Abstract

The present invention discloses a submersible mixer experimental device which comprises a submersible mixer (1) and a support column (2). The tail of the submersible mixer (1) is fixed at the middle of the support column (2). The submersible mixer experimental device also comprises a first pull force sensor (4) for measuring thrust and a second pull force sensor (5) for measuring a torque. One end of the first pull force sensor (4) is fixedly connected to the upper end of the support column (2) through a steel wire rope, and the other end of the first pull force sensor (4) is connected to a first fixed point (6) through a steel wire rope. One end of the second pull force sensor (5) is fixedly connected to the upper end of the support column (2) through a steel wire rope, and the other end of the second pull force sensor (5) is connected to a second fixed point (7) through a steel wire rope. The experimental device of the invention can measure the thrust and torque of a submersible mixer at the same time, and the measurement precision is high.

Description

technical field [0001] The invention belongs to the field of fluid machinery and engineering technology, in particular to a submersible mixer experimental device capable of simultaneously measuring thrust, torque and power of a submersible mixer with high measurement accuracy. Background technique [0002] Submersible mixer is a new type of high-efficiency sewage treatment equipment, which is widely used in environmental engineering to treat sewage in aeration tanks and anaerobic tanks of industrial, urban and rural sewage treatment plants. It is the main equipment of sewage treatment plants. The submersible mixer is installed horizontally in the sewage tank. The water thrust and the distribution of the stirring flow field are the key performances of the submersible mixer, which directly affect whether the sewage treatment can meet the standard. Moreover, there are many factors that affect the distribution of the flow field, such as the placement angle of the submersible mix...
