"Pipeline circulating pump" is a single suction single stage centrifugal pump, belonging to one of the column pumps, and other vertical multistage pumps, column type multistage pumps. The pipe circulating pump has the characteristics of coaxial output transmission data, simple installation, environmental protection and energy saving motor. After mastering the characteristics of the pipeline circulating pump, there is no doubt that you will wonder how to choose the model of the pipeline circulating pump. Then, we will choose the 5-level method for the model of the shared pipeline circulating pump.

(1) According to the design scheme of sewage treatment plant, several kinds of different types of pipeline circulating pumps with different total flow are selected from the comprehensive spectrum of the pipeline circulating pump or the characteristic table of the commercial sample of the pipeline circulating pump. The pump head of the selected design scheme of the pipeline circulating pump is consistent or close to the pump head of the design scheme of the sewage treatment plant. But the total flow is likely to be slightly different.

(2) According to the total flow rate of the sewage treatment plant design scheme and the total flow of the selected single pump, the number of centrifugal pumps in different types of pumps is defined and the requirements are met. Draw the flow path of the design scheme of tap water or drainage pipe in irrigation area, and carry out linear fitting between the total flow process line of sewage treatment plant and the total flow process line of irrigation and drainage design scheme when different number of circulating pumps are selected to operate, and check whether the regulation of the change of irrigation and drainage flow can be achieved. If the linear fitting total flow process line is close to the flow plate process line of irrigation and drainage design scheme, the number of selected pumps will be explained; Basically, the irrigation regulations can be integrated. In the allowable area of irrigation, the total flow process line of the design scheme can be adjusted appropriately to make the two conform to each other.

(3) According to the type and quantity of pumps in the preliminary examination. Provide pipes and accessories, and draw the characteristic curve of the pipeline, find out the working point of the pipeline circulating pump, and define the installation elevation of the pipeline circulating pump.

(4) Optional engine and auxiliary machine equipment, and the structure and layout method of water pump room are formulated.

(5) According to the selected model and specification of pipeline circulating pump and the characteristics of supporting facilities and equipment, and in accordance with the technical standards of economic development, the cost of capital construction and operation cost shall be effectively carried forward, and the types and quantity of effective pumps shall be clarified.

Three outstanding advantages of pipeline circulating pump are as follows:

1. Coaxial output transmission data: centrifugal impeller is connected with motor shaft immediately, environmental protection, energy saving and low noise, which can balance axial and radial load caused by pump operation.

2. Simple installation: the access specification is the same, located in the same line, and the structure is simple. Easy to maintain, when repairing centrifugal impeller and sealing parts, do not dismantle the pipeline.

3. Environmental protection and energy saving motor: secondary energy efficiency, energy saving and power saving, explosion-proof fan can be selected, high temperature and corrosion resistance, long life
