The flyweight of steam turbine emergency trip set, also known as the impactor, is a key component used to trigger and operate the emergency trip set. Its main function is to quickly disconnect the steam or power supply to the turbine in case of emergency, to ensure the safe operation of the system. During normal operation of the steam turbine, the impactor remains stationary for a long time, and after continuous operation for 2000 hours, an oil injection test needs to be conducted. However, due to the emergency trip set installed on the main oil pump shaft at the front end of the rotor, it is not convenient to observe the status of the impactor during the test.

The HZQW-03E rotational speed monitor has solved this problem. It is specifically designed for monitoring the speed of rotating machinery, providing multiple parameter measurements and early fault prediction for the safe operation of rotating machinery. Unlike ordinary speed meters, while monitoring the speed, it can also observe the status of the impactor and record the turbine speed during the impactor action.

By using the HZQW-03E speed meter, the characteristics and trend data of the flyweight state changes can be obtained, which helps to detect and prevent potential faults in a timely manner, and improves the availability and safety of the steam turbine. It can effectively reduce the risk of accidents and protect the turbine and its surrounding equipment from serious damage.
