Working principle
Special note: The control methods of our company's non-negative pressure (no suction range) variable frequency voltage stabilized water supply equipment series products are divided into non-touch screen intelligent operation control methods and touch screen intelligent operation control methods. If users choose touch screen control, please indicate it in the contract. .
Set the water supply pressure value required by the user through the controller on the control cabinet panel. The microcomputer monitors the municipal pipe network pressure at all times. When the pressure is lower than the pressure required by the user, the microcomputer automatically controls the start of the frequency converter and adjusts the speed of the water pump. Increase until the pipe network pressure rises to the pressure required by the user, and the well controls the water pump to run at a constant speed for constant pressure water supply. When water consumption increases, the rotation speed increases; when water consumption decreases, the rotation speed decreases to ensure constant water pressure for users. The lower the pressure of tap water, the higher the speed of the water pump. The higher the pressure of tap water, the lower the speed of the water pump. When the pressure of tap water is greater than or equal to the pressure required by the user, the water pump stops running. During operation, the equipment makes full use of the original pressure of tap water and ensures that the user's water supply pressure is constant.
During the operation of the equipment, the microcomputer always monitors the pressure of the municipal pipe network and system, automatically controls the negative pressure suppressor and the steady-flow energy storage device to suppress the generation of negative pressure, which not only fully utilizes the pressure of the municipal pipe network , the fork ensures that no negative pressure is generated and does not have any adverse impact on the municipal pipe network, ensuring water safety. When the water supply in the municipal pipe network is cut off or the flow rate is insufficient, the equipment automatically shuts down and starts automatically when the water supply is restored. After a power outage, the system automatically restarts to restore constant pressure water supply.
This set of equipment adopts an advanced intelligent control system that can safely realize automatic control and detect faults and automatically switch, thereby achieving unattended functions and saving personnel expenses. Specific functions include
●Water pump, power supply, voltage, fault self-test, alarm and protection. ●Automatic switching function when water pump fails
●Automatic frequency conversion function and soft start function. ●Water pump automatic timing switching function.
●Vacuum suppression function. ●Low flow shutdown and pressure maintaining function.
●Automatic liquid level detection and alarm function. ●Fully automatic operation with unattended function.
