Global pumps high-pressure systems supplier RMI Pressure Systems says its newly launched On Demand Intelligence (Odin) control system enables pumps drive motors to function at their optimum speed and provide maximum output while using minimal energy.
Odin is a robust and reliable control logic system that is capable of rapid response and close control of system pressure. The control technology is available in three modes: local, remote and prime, which can be arranged to provide the level of control appropriate to each application.
In local mode, the controller uses information provided by a pumping station to control the pressure and speed of the motor. This mode can be used for descaling operations in steel mills and smaller underground mining applications.
Remote mode uses additional pressure signals from equipment located away from pumping stations, such as the roof supports of a mine. It enables a pumping station to be more responsive and efficient in providing hydraulic flow.
Odin prime is designed predominately for longwall mining applications and can interrogate individual components of the system to allow changes in demand to be fulfilled in the most efficient manner. The control system regulates the speed of all the pumps in the system and matches the pressure and flow characteristics required by the shearer and the roof supports.
“Taking account of pressure signals at the valve banks and digital information, Odin prime calculates the anticipated roof support movements and the subsequent increased demand for hydraulic fluid from the pumpstation. Calculating the changes in demand before they occur allows the pumps to modulate in speed and thus change the flow and pressure, which enables the roof supports to operate in a more responsive manner, which can increase the productivity of the mine,” explains RMI.
