AC Variable Speed Drives For Water & Wastewater Applications

The IMO Jaguar VXA (Aqua) range has been specifically designed to fulfil the exacting requirements of the water industry In close consultation with water industry experts worldwide the VXA (Aqua) drive has been developed to offer a three pronged approach to reducing cost and wastage for those in the business of handling water. Reducing energy usage Whether it is simply a case of reducing speed to suit the demand, automatically stopping a pump during periods of low flow rate or one of the drives specific energy saving functions, energy conservation is always a major consideration in pumping systems....

Optimum control for water and wastewater applications Water purification plant, wastewater, clean water and sewage treatment plants The IMO Jaguar VXA (Aqua) drive has specific water industry features that suit almost all of the applications found within water treatment plants. In addition to accurate process control the VXA can also significantly reduce energy usage and maintenance costs. Pumping stations and pressure boosting stations With cascading pump control, 4 built in PID controllers, dry pump detection, condensation prevention and linearization functions the VXA is ideally suited to...

Specific Functions for Use in Water Treatment Cascade Control Cascading pump control is the function that controls multiple pumps with one inverter. The pumps are controlled with a combination of inverter drive and mains driven motors. This can be applied in a large-scale water treatment plant. Pressure sensor In cascading pump control, the signals of flow rate and pressure sensors are controlled by the PID controller built into the inverter. Each pump is driven either by the inverter or mains driven motor according to the switching signal from the inverter. The pumps are controlled only by the...

2. Inverter drive floating method (FLOATING) The system for this method is configured by combining the motors that can be switched between inverter drive and mains driven motor (M1 to M4) and auxiliary motor that are mains driven (MA). The motors are driven by the inverter with variable speed control at start. When the desired discharge flow rate cannot be achieved with the first motor, operations FLOATING-1 or FLOATING-2 can be selected. Pressure sensor Control unit for pump The first motor: to be a mains operated motor. Second and subsequent motors: operated by inverter drive Auxiliary pump...
