变频器联机泵组
485 TECHNOLOGY
VF系列变频水泵采用全不锈钢卧式多级离心泵+先进的变频控制
系统+高品质隔膜压力罐+全不锈钢五通逆止阀+工业级压力传感
器等高品质成套部件系列，组成了当今最为可靠与经济的变频恒
压供水系统。
Product features/产品特点
1. 联机控制：采用485通讯方式，单个系统中最多可允许6台水
泵联机工作。
2. 通讯及定时功能（交替运行功能）：变频器之间能够互相通
讯，可以按设置的时间顺序切换工作水泵，使每台网络中的
水泵工作总时间趋于相近。
3. 主从机自动识别：在上电时对系统中的工作站号自主识别，
自主建立主从关系，无须人工干预。
4. 故障检出及自动切换：如果网络中一台变频器发生故障，变
频器能自动跳过故障变频器，能将控制权顺序交付给网络中
下一顺序号的变频器，自动进行主从切换。以确保在任何情
况下都有变频器作为主机在指挥工作，从而保证供水系统能
继续运行。
5. 智能切换：当水泵工作到设定工作的总时间时，为实现管网
系统的压力恒定不变，可实现智能切换。

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.
1. Prevent frost cracks: using the internal program of inverter switch to non-stop
function, which can keep the pump running, to prevent the pump frost crack.
2. Selfreset after instantaneous power failure: after the power failure or other reasons
cause the pump stop running, the inverter records last running state. For example,
when the power input again, the system will restore operation according to the final
memory mode (Please cut off the power when stop running for a long time).
3. High pressure alarm: operation pressure reach to the set pressure value, the
controller alarm, at the same time alarm lights flashing. When the pressure of pipe
network lower than the set pressure value, alarm automatically remove and restore
operation.
4. Low water level alarm: the water inlet pipe with any water, the system will stop
automatically, at the same time alarm lights flashing. There are two ways for
detection of water level. One is internal testing method, the other is the low water
level sensor testing.
5. Parallel operation: water supply system allow up to 6 pumps in parallel.
6. Water shortage protection: when the water pipe network system fault, that will stop
the pump work, avoid motor burn down.
7. Alternately running(Using for parallel operation): when the pump parallel operation,
to prevent the main pump run continuously, affect the service life of pump.
8. Skip the failure pump running: when a variable frequency pump in the network has
abnormal behavior, that will automatically alarm and stop the pumps running. And
then switch to a normal variable frequency pump.
9. Automatic inspection function: in a single pump working condition, the pump can
automatically working according to the set time, in case of any pump corrosion
occurs due to long time no use.
