Embodiment Construction

[0036] The present invention is specifically described below according to accompanying drawing:

[0037] as attached figure 1 In the feedwater pumping station feedback control system shown, the water level of the upstream 1 changes frequently. According to the characteristics of full adjustment of the pump blades, the upstream-water pump feedback control part 11 works to control and change the blade angle of the working pump I2 according to the water level change. When the head is high, the blade angle of the working pump I2 is reduced to reduce the flow rate; correspondingly, when the head is low, the blade angle of the working pump I2 is increased to increase the flow rate, so that the shaft power of the power machine is kept at about the rated value at full load operation, the efficiency is obviously improved; the flow rate of the working pump I2 changes, and the built-in logic of the pump-pump speed control part 12 sends a control signal after receiving the flow signal at ...

Abstract

The invention relates to the pump station automation control field, and especially relates to a water supply pump station feedback control system; the whole system comprises a programmable logic controller control portion with different functions: an upstream-water pump feedback control portion can carry out full adjustment automation control on water pump blade angles; a pump-pump speed control portion controls speed changes of a work pump according to the water inflow; a safety valve feedback control portion can reduce the backflow impact damage effects on the work pump and pipelines by a water hammer when the pump stops; a water reservoir feedback control portion can regulate and control the water reservoir water inflow. The automation feedback control system is flexible and various in functions, thus improving pump station management efficiency, and improving pumping station operation problems.

Description

technical field [0001] The patent of the present invention relates to the field of automatic control, in particular to a feedback control system for a water supply pumping station. Background technique [0002] The pumping station project is a water conservancy project that uses pump units and flow-through facilities to transfer and convert energy, realize water body transportation, and avoid disadvantages. The pumping station engineering facility is a specialized hydraulic structure, which is the main project of water lifting and irrigation, water lifting and drainage, and water diversion projects. It forms a water conservancy system together with other general hydraulic structures, ditches, canals, rivers, and reservoirs. With the development of industrial and agricultural production and the continuous progress of science and technology, the wide application of automation technology, and the continuous improvement of the level of control technology, the application range o...
