Abstract

The invention discloses a vacuum jet siphon drainage equipment monitoring system based on a PLC, which comprises a vacuum jet siphon water taking system consisting of a submersible vacuum jet rectifier, a siphon and a siphon outlet regulating valve, a vacuum power system consisting of a vacuum tube stop valve, a water ring vacuum pump, a buffer tank, a liquid-gas exchange box and a make-up pump, an automatic monitoring control system consisting of the PLC, a touch screen, a motor control relay, a flow signal sensor, a pressure signal sensor, a temperature signal sensor, a water level signal sensor and a motor comprehensive protector which are electrically connected with the PLC, and a valve opening degree sensor. The motor comprehensive protector and the motor control relay are respectively connected with a motor of the water ring vacuum pump, and the PLC is electrically connected with the siphon outlet regulating valve and the vacuum pipe cut-off valve. The system is used for improving the water conveying efficiency of the siphon pipeline, automatic operation and continuous controllability of the system are achieved, and the system has the advantages of being simple in structure, reliable in operation and high in integration degree.

Description

technical field [0001] The invention relates to the technical field of fluid monitoring and control, in particular to a PLC-based vacuum jet siphon drainage equipment monitoring system. Background technique [0002] Siphon, an ancient natural phenomenon, makes natural power such as flow field force, gravity, and atmospheric pressure a natural power source for water. At present, most water intake processes use pumping as the main transportation method, which has disadvantages such as high energy consumption, easy cavitation water hammer, high maintenance cost, more affected by boundary conditions, low pump efficiency, and low intelligence level. [0003] Vacuum jet siphon drainage is a large-diameter, large-flow, fast and efficient water delivery technology and equipment. It breaks through key technologies such as vacuum siphon, submersible rectification, and drainage control, and integrates industrial intelligent manufacturing to form a large-scale drainage and drainage meth...
