Case I
Application of Senlan Inverter in Refinery
I General
Frequency-conversion speed regulation is a kind of effective speed regulating manner, with high accuracy, wide range of speed regulation, and easy operation. Further, the self-contained RS485 munication interfaces on inverters can munications with control system so as to easily monitor work situations of the system and benefit operation of normal production. In 2002, pany carried out automation transformation for the extraction system of liquefied gas by pressors in the refinery. After this transformation, not only the process operating level is enhance greatly, but energy-saving is increased by about 20%, and economic benefits are very significant.
II Main Features of Senlan SB61 Inverter
The propane is the essential equipment of this system and has certain requirements for reliability, starting torque, and dynamic response of inverters. You can select the SB61 All-round Inverter produced by pany. It uses advanced vector control algorithm, plete functions, and can be freely applied in various industries. It is available to select V/f open-loop, V/f close-loop, vector control without PG, and vector control with PG; available to select operating modes of key board, external terminals, and functional terminals; and there are RS485 munication interfaces that can worked cont
