Constant-pressure water supply system based on PLC technology

Abstract

The invention discloses a constant-pressure water supply system based on a PLC (Programmable Logic Controller) technology. The constant-pressure water supply system based on the PLC technology is characterized by comprising a water supply pipeline, a PLC, a frequency converter, a display, a water pump group and a plurality of pressure sensors, wherein the pressure sensors are arranged on the water supply pipeline; and the PLC is provided with an automatic timing water supply module and a warning module. The constant-pressure water supply system has the real-time water pressure detection function and various water pressure regulation modes; the data processing capability is high; the water supply is stable and reliable; and the practical value is high.

Description

technical field [0001] The invention relates to the technical field of municipal water supply equipment, in particular to a constant pressure water supply system based on PLC technology with novel design and good automatic control effect. Background technique [0002] There are many disadvantages in the traditional water tower water supply method: secondary pollution of water, unbalanced peak and low water consumption, easily damaged pipeline valves, and high maintenance costs. The newly emerging constant pressure water supply method has the advantages of stable system, powerful function and good energy saving effect, so it is more and more used in the domestic fire water supply system of multi-storey residential quarters or the water supply system of other occasions. However, the constant pressure water supply method in the prior art still has some deficiencies, such as imperfect monitoring methods, high construction costs, and unfavorable popularization, etc., so it needs ...
