School water supply pump

Performance and characteristics of school water supply pump products:

1. Fully functional: The water supply pump has various automatic maintenance functions such as overload, short circuit, overcurrent, etc. The equipment operates stably and reliably, making it easy to use and maintain. It has functions such as stopping the pump due to water shortage and automatically switching the water pump operation on time.

2. Reasonable operation: Multiple pump circulation soft start control methods are selected for the feedwater pump to reduce the impact and interference of direct start on the power grid. The operating principle of the main pump start is: start first stop, stop first start, equal opportunities, which is conducive to extending the life of the unit.

3. Hygiene and energy conservation: Replace traditional rooftop water tank water supply methods to reduce secondary pollution. After variable frequency control, the motor speed is adjusted to achieve a constant pressure in the user's pipeline network, and the energy-saving power can reach up to 60%. During normal water supply, the pressure activity can be controlled within ± 0.01Mpa.

4. High degree of automation and intelligent operation: The feedwater pump is controlled by an intelligent central processing unit, and the operation and switching process of the working pump and standby pump are fully automated. The fault is automatically alarmed, and users can intuitively and quickly find the cause of the problem from the human-machine interface. Using PID closed-loop regulation, with high constant pressure accuracy and minimal water pressure oscillation. After setting various functions, it can truly achieve unmanned operation.

5. Intelligent variable frequency controller (optional): Each water pump in the unit uses an intelligent variable frequency controller independently, which can maintain a constant pressure under drastic changes in flow rate, making the water pressure in the user's pipeline less unstable when switching between pump operation states, resulting in higher water supply quality and better energy-saving effect (saving more than 30% of electricity compared to general water supply equipment).
