The variable frequency constant pressure water supply equipment system adopts intelligent control technology, with manual/automatic switching and timed rotation of main and auxiliary pumps, achieving the goal of energy conservation and consumption reduction. One frequency converter can achieve the effect of multiple frequency converters and save electricity. The starting current of the soft start water pump auxiliary pump is 200-300% of the rated current. We have adopted two operating modes
1. Incremental operation mode
2. The alternating operation mode is the basic function of constant pressure variable frequency water supply. When all water pumps are stopped and restarted, the initially started pump operates with variable frequency speed regulation, and this pump is the main pump. Start the main pump alternately every time or at any set time to prevent a pump from starting frequently.
The variable frequency water supply equipment adopts a closed-loop control method, continuously collecting data, providing feedback, and regulating the speed of the water pump to achieve a constant water supply pressure in the user's pipeline network.
The pneumatic water supply equipment adopts an open-loop control method, which collects signals, provides feedback signals, and controls the water pump. The speed of the water pump cannot be adjusted, and only a small amount of stable water supply pressure can be achieved using a diaphragm stabilizing tank
Types of Control Methods for Variable Frequency Constant Pressure Water Supply Equipment
1. Pneumatic water supply
2. Self irrigation water supply method for domestic water pool
3. Self suction water supply method for domestic water pool
4. Variable frequency water supply method for water wells
The equipment adopts submersible pump frequency conversion control, which can be one pump or control multiple pumps. Each pump is automatically put into operation according to changes in water consumption.
