Voith successfully commissions the first two VECO-Drives

Published on: 

Voith commissioned the first two VECO-Drives at a coal-fired power station in China. Since February, the two systems have already been running reliably for over 6,000 hours, improving not only the overall efficiency of the drive train but also significantly decreasing noise emissions and vibrations. Various monitoring indicators such as temperature, vibration and pressure were measured and confirmed to be within a safe range. Additionally, the team measured a power transmission efficiency of the complete speed regulation system of approximately 97 percent. Lower than specified noise emissions were attained.

The two VECO-Drives have passed all necessary tests for its customer, Guangzhou China Resources Thermal Power Co., Ltd. and were put into operation in February 2020. The units are part of the customer’s energy-saving transformation project of the electric feed water pump unit to replace the original speed control device.

Voith's variable speed VECO-Drive increases input speed and generates a high output speed that drives the compressor or pump. Frequency controlled servo motors are used together with a superimposing planetary gear to adjust the output speed according to process demand.
