CONTROL STATION (CS)
The purpose of our control stations is to provide pump unit control, processing of instrument signals and the pump unit emergency tripping.
The control system can be based on PLC by Bradley, Siemens, Mitsubishi, Beckhoff or any other manufacturer requested by the client. PLC enables feeding the HPP operation parameters into the memory, and sending all process parameters of the pump unit to the client’s upper level of automation via RS-485 or Ethernet interface. The control station can be provided with a frequency converter by Danfoss, Mitsubishi, ABB, Schnider Electric, of other VFD requested by the client
Pump unit control algorithms include the PID control system (automatic maintenance of the preset flow rate and discharge pressure values by adjusting the electric motor speed and the shut-off valve). It allows to maintain the pump units operation within the maximum efficiency range (and hence the minimum energy consumption) due to the fact that the system itself selects the required motor speed of the pump unit to ensure the preset flow rate and discharge pressure values. The automation facilities will ensure the preset pressure and flow rate values at the pump unit outlet even with changing injection conditions such as well intake capacity.
