Building tr*ning table
The tr*ning table is made of iron double-layer matte dense spray structure. The tabletop is fireproof, waterproof, wear-resistant high-density board. It has a solid structure and a rectangular closed structure with beautiful appearance. It has two large drawers and cabinet doors for placing tools and storing materials. The desktop is used to install the power control panel and provide a spacious and comfortable work surface. The tr*ning table is also equipped with four universal wheels and fixed adjustment mechanisms for easy movement and fixing.
PLC
PLC uses Omron CP series controller and HostLink communication protocol, providing a PLC development environment, allowing students to design control solutions by themselves.
(1) Constant pressure water supply for domestic water supply network
(2) Timed pressure control based on d*ly cycle can be realized to meet the demand of water supply pressure change
(3) The dormant small pump can be started at night to achieve maximum energy saving and realize domestic water supply under small flow
(4) In the case of fire alarm, the fire pump can be automatically started to complete the constant pressure water supply under fire mode
(5) PID control with host computer system can be realized
Manual control device
The control system adopts manual control and automatic control. The manual controller is very important in practical engineering applications. The addition of this device has the following functions:
