Variable speed pump fixing
1 pump can be operated at adjustable speed, and the rest of the pumps can be operated according to the data output of the inverter for power frequency ON and OFF.
And the role of constant pressure control for pipelines. The line pressure is maintained according to the PI function of the inverter that controls the variable speed pumpPoor persistence.
Up to 1 adjustable speed pump and 3 commercial power constant speed pumps can be operated.If you have a DO-A3 card:Up to 1 variable speed pump and 11 commercial power constant speed pumps can be operated.
Variable speed pump cycle switching mode 1
Variable speed operation is carried out on one pump, and when the working pressure of the pipeline is insufficient, it is switched to a commercial power supply and the next pump is performedVariable speed control to achieve constant pressure control of the pipeline. Compared with the fixed pump mode, the variable speed control of the pump with adjustable speed operation will be carried out to realize the constant pressure control function of the pipeline. Relative to the fixed mode of the pump, the variable speed controlled pump can be cyclically switched for operation. The continuity of the differential pressure in the line is maintained by the PI function of the inverter that controls the variable speed pump. To apply this method, the DO-A3 option is required. Up to 5 pumps can be operated with variable speed cycle switching.
Variable speed pump cycle switching mode 2
Adjustable speed control is carried out on a certain pump, and when the working pressure of the pipeline is insufficient, it is switched to a commercial power supply, and the variable speed control of the next pump is carried out to realize the constant pressure operation of the pipeline. In contrast to the fixed pump method, the pump with adjustable speed operation will be cyclically switched. The PI function of the inverter that controls the variable speed pump maintains a constant pressure difference in the line. Up to 3 pumps can be operated with variable speed cycle switching.If you have a DO-A3 card:Up to 11 pumps can be operated with variable speed cycle switching.
features
Depending on the pressure or flow rate, it is possible to run at the same timeThe function of circulating pump cutting can prevent the unbalanced operation time between each pump and achieve stable operation.
The above is for the productThe introduction of Yaskawa/Yaskawa W1000 inverter mainly understands that there are two kinds of productsVariable speed pump cycle switching mode, and common features.
