Value pair of voltage and frequency

| 0

The optimum frequency should be selected based on the medium: 100 Hz for water, 300Hz or higher for gases, 50Hz or lower for oils. Thereafter, the position of the working line of the pump (straight line from maximum pressure to maximum flow) depends on the used amplitude and shifts almost parallel to the origin when it is reduced. Since the operation with gases is more flexible, both amplitude and frequency can be used to control the flow rate (and pressure). The actual flow rate always depends on the working line and the existing backpressure in the system. The value pair of flow and pressure is always on the working line which is conditional to the selected operating parameters (frequency and amplitude).
