Variable speed constant pressure water pump is a pump device that uses variable frequency technology to control operation and is used to maintain a constant pressure in a water supply or liquid supply system. It is usually composed of a horizontal centrifugal pump and a constant pressure variable frequency controller, a pressure tank, and a pressure gauge. It uses advanced pressure sensing technology to collect real-time pipeline pressure and adjust the pump speed.
Its core feature is to adjust the motor speed through the frequency converter, thereby dynamically adjusting the variable speed constant pressure water pump output pressure according to changes in water consumption or flow, ensuring that the system is always within a stable pressure range.
- The built-in pressure sensor of the equipment detects the pressure in the pipeline in real time.
- When the system pressure is lower than the set value, the inverter increases the pump speed, increases the flow and pressure.
- When the pressure is higher than the set value, the inverter reduces the variable speed constant pressure water pump speed or shuts down.
- Through this dynamic adjustment, constant pressure operation is achieved.
Features:
- Constant pressure: The system pressure is monitored in real time through the pressure sensor, and the variable speed constant pressure water pump speed is automatically adjusted to maintain the set value.
- Energy saving and high efficiency: The motor speed is adjusted according to actual needs, avoiding the energy waste of traditional fixed speed pumps.
- Intelligent control: Usually equipped with an intelligent control system, which can realize functions such as automatic start and stop, overload protection, and water shortage protection. (Mobile phone APP control is optional)
- Quiet operation: Adopting frequency conversion technology, it runs smoothly and has low noise.
- Compact structure: Horizontal design, easy installation, small footprint, suitable for home use.
advantage：
- The interface is simple and easy to operate, and no professional is required for testing or maintenance.
- Compared with conventional water supply methods, variable frequency constant pressure water supply can save energy by up to 20%~60%.
- The intelligent variable frequency controller can provide soft start and soft stop, thereby extending the service life of the variable speed constant pressure water pump.
- The product can adapt to wide voltage, especially in areas with large voltage fluctuations.
- The constant pressure variable frequency controller can fully protect horizontal pump centrifugal pumps or vertical multi-stage centrifugal pumps, and minimize property losses caused by improper use of the variable speed constant pressure water pump.
- The high-definition display panel and intuitive display make it quick and easy to query and set real-time pressure values.
