Inverter constant pressure water supply system experiment desk

"Tr--ning Device of Frequency Conversion Constitutional Water Supply System" integrates PLC, frequency conversion speed regulation, process control, and engineering configuration technology. It consists of two major parts of the six -story residential fire and water supply system (physical model). The control platform two parts include Programmable controller, inverter, inverter magnetic driver pump, dormant pump, fire pump, pressure transmitter, pressure instrument, water pipeline, fire hydrant, home water faucet, storage pool and other engineering equipment. The control platform uses PLC+inverter The open -type control structure can complete the tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning tr--ning for teaching and research inverter and constant pressure water supply technology. School electrical automation, building automation, building electrical, intelligent architecture and other professional comprehensive tr--ning equipment.

Second, systemic characteristics

The control platform adopts an open control structure of PLC+inverter, providing configuration software and PLC development environment, which allows students to design control solutions themselves and have strong flexibility.

The control platform has multiple protection mechanisms such as heat overload protection, overcurrent protection, leakage protection, grounding protection, ground frequency and frequency conversion link control.

The control system can simulate the real water supply system. There are two control methods: automatic control and manual control. When the automatic control f--ls, the system runs by manual control.

All control objects use st--nless steel and organic glass devices to ensure that they are not rust and are not easy to aging. Simulating the six -story building to the water system, which has two types of waterway models: living water system and fire water system; the power system consists of four water pumps, two of which Conventional inverter cycle pump, a dormant pump, a fire pump, can simulate conventional living water supply systems, fire water supply systems, and small traffic water supply systems at night, and can vividly simulate the typical structure of the dr--nage system for the building.
