The Application of Frequency and Speed Converting System in Korla Shanshan Oil Pipeline

The structure and working principle of frequency and speed converting system are introduced. With stepless speed regulation, this system can auotomatically regulate flow rate of pump and outlet pressure of pumping station to realize automation control of transportation process without throttling during operation. With this system. the transportation cost can be greatly reduced. The authors consider that this con verting system is an important and indispensible equipment to oil pipeline.
