VFB series variable-frequency pumps adopt stainless steel horizontal type impeller pump+advanced frequency conversion control system+high quality membrane pressure tank+stainless steel five way non-return core+lndustrial-grade pressure sensor and high quality parts sets. Make up the most reliable and economic variable frequency constant pressure water supply system.
1. Paraller control：adopt the RS-485 communication mode. Allow up to 6 pumps parallel work in a single system.
2. Communication and timing switching(alternate running function): for the inverter can communicate with each other. The working pump can be switched by setting the time in order. To make the total working time of each pump in the network tend to be similar.
3. Master-slave pump is automatic identification system: when the power on, the workstation of the system be identified automatically, and set up a master-slave realtionship independently, without human intervention.
4. Fault detection and automatical switching: if a inverter in the network. Automatic master-slave switching. This for in all cases, there is the inverter as a host to work in the command. To ensure water supply system keep on running.
5. Intelligent switching: in order to realize the pressure of the pipe network system is constant, when the pump working time to reach the set total time, which can be realized intelligent transition.
