Intelligent Pump System
The intelligent pump system is composed of a control panel, motor with sensor, pressure sensor, and a water pump. The current case is 220V AC/380VAC power supplying the controller to control the motor, meanwhile the motor sensor transfers the location signal to the controller. The pressure sensor in the pump system transmit the pressure value to the controller, based on these pressure value, the controller carries on the real-time speed control. thereby achieve the function of constant pressure of the whole pump system.
Moreover, the controllers can be connected to the buses, the controller can control different motors, if the pressure is insufficient, the other motors would work simultaneously to keep the constant pressure. meanwhile, to avoid other pumps from rust.
You can refer to the diagram, once the pressure is reduced, the motor would speed up to pump more, to keep the system pressure stable. Because controllers are connected to the buses. In case, the water demand is too great that one pump( pump1) can’t meet, the system would open the pump2, pump 3,… intelligently. Opposite process can work as well. All the process is automatically, by close loop control. The intelligent system can help to saving enrgy and keep constant water pressure.
The pump system used permanent magnet motor, compared to induction motor pump system. Thanks to its advantages listed below, which is to be used that have variable water requirements provides up to 35% energy saving and improves the pump’s service life.
Soft Start and Longevity
Excessive current drawn during the star-delta of the electrical motor (starting current) and the mechanic loads are eliminated thanks to the soft start and stop features of this system. As a result, longevity of the motor equipment improves and maintenance costs decrease.
Economical Run and Constant Output Pressure
When the conventional electric motor pump switches on, it keeps working at its constant speed, most of the time, the pump doesn’t need the full load operation, this wastes a lot of power long terms. Pumps with our permanent magnet motor, works at an optimum speed (rpm) to meet the real time water needs and provides great deal of energy savings as well as producing targeted constant output water pressure.
1. Pump used permanent magnet motor systems.
1.1 Purpose: In variable speed pumps, the conventional motor system is Induction Motor+ VFD (Variable Frequency Driver); the permanent magnet motor system has higher efficiency and wider speed range, which can meet the variable speed pumps better. This case is trying to optimize the motor system to develop a higher cost performance variable speed pump system.
