Experimental device of building constant pressure water supply system

"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.

1. Product introduction

The device is based on the physical object of the automotive instrument system to fully display the composition and working process of the automotive instrument system.

It is suitable for the teaching needs of the school's theory and m--ntenance tr--ning for automotive instrument system.

2. Functional characteristics

1. The real -operated car electronic instrument system, fully display the composition of the automotive electronic instrument system.

Various sensors and switches connected to the instrument system to simulate the work of the signal source of the instrument, which can truly demonstrate the work process of the car instrument system.

2. The teaching board panel adopts the ** aluminum -plastic board with strike, pollution resistance, fire prevention, and moisture -proof, and spray primer p--nt on the surface by special crafts; working principle.

3. The detection terminal is installed on the teaching panel, which can directly detect the electrical signals of the circuit components of the car electronic instrument system on the panel, such as resistance, voltage, current, frequency signals, etc.

4. Demonstration panel parts use 1.5mm cold plate stamping and forming structure, beautiful appearance; the ch--n part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop on the base of the teaching plate. , Easy to place data, light detection instruments, etc.

5. The work of the teaching board adopts a normal 220V AC power supply, which is converted into a 12V DC power supply by transformed by the internal circuit. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short circuit function.

6. Machinery assembly and fitter assembly virtual simulation software:

This software is developed based on Unity3D. It can choose level 6 image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, typical mechanical mechanisms (virtual disassembly of gasoline engine engines) The software is an overall software that cannot be separated by separate resources.
