Problems solved by technology

When the pump is used in the scene of providing kinetic energy for the liquid, there is a high requirement for the flow rate of the liquid; in the conventional technology, it is difficult to meet the high kinetic energy requirements of the pump when the liquid delivery path is long by using a single pump. Analyze the flow velocity of the liquid at different positions to keep the flow velocity of the liquid at different positions within the controllable flow rate range, and prevent the decrease of the liquid flow velocity in the long conveying path from affecting the kinetic energy and head of the liquid at the liquid outlet

Embodiment Construction

[0021] Such as figure 1 as shown, figure 1 It is a multi-stage linkage pump operation control system proposed by the present invention.

[0022] refer to figure 1 , the multi-stage linkage pump operation control system proposed by the present invention includes: liquid channels, n pumps, n detection modules, and n adjustment modules;

[0023] n pumps are evenly arranged in order from the inlet to the outlet of the liquid channel, n pumps divide the liquid channel into n+1 areas, denoted as A 1 、A 2 、A 3 ...A n+1 ;

[0024] n detection modules are used to detect A 2 、A 3 、A 4 ...A n+1 The average flow velocity of the liquid in the area, denoted as V 1 , V 2 , V 3 ...V n ; Among the n detection modules, any two adjacent detection modules are connected by communication;

[0025] The n adjustment modules are respectively used to adjust the working power of the n pumps, and the n adjustment modules correspond to the n pumps one by one;

[0026] The jth detection mod...

Abstract

The invention discloses a multistage linked pump operation control system. n pumps are uniformly arranged from an inlet to an outlet of a liquid channel in sequence, and divide the liquid channel inton+1 areas; n detecting modules are respectively used for detecting average flowing speeds of liquid in n areas; any two adjacent detecting modules in n detecting modules are in communication connection; n adjusting modules are respectively used for adjusting working powers of n pumps; and the jth and j+1th adjusting modules are acted according to a comparison result of the average flowing speedsbetween a target area and the two adjacent areas. The multistage linked pump operation control system uses the flowing speeds of the liquid in two areas near the target area for detecting if the flowing speed of the liquid in the target area is in a preset range, adjusts the flowing speed of the liquid in the target area through changing the working powers of the pumps to keep in a controllable range, guarantees keeping of ideal kinetic energy of the liquid in the outlet, and uses multiple pumps for realizing intelligent control of the flowing speeds of the liquid.

Description

technical field [0001] The invention relates to the technical field of pump control systems, in particular to a multi-stage linkage pump operation control system. Background technique [0002] Pumps are widely used in industrial applications and they consume huge amounts of energy. About 15% of all electricity consumed by the industrial sector is consumed in pump applications. As the price of electricity continues to increase and the need to reduce energy consumption arises, monitoring the energy efficiency of pumping systems becomes even more important. When the pump is used in the scene of providing kinetic energy for the liquid, there is a high requirement for the flow rate of the liquid; in the conventional technology, it is difficult to meet the high kinetic energy requirements of the pump when the liquid delivery path is long by using a single pump. The flow velocity of the liquid at different positions is analyzed to keep the flow velocity of the liquid at different...
