The functions of the turbine speed impactor monitoring device RZWW-03A are as follows:
1. Real time speed display: The RZWW-03A device can display the current speed of the steam turbine in real time, which is crucial for operators as it allows them to keep track of the equipment's operating status and detect and handle any abnormal situations in a timely manner.
2. Record the highest speed: This device can capture and record the highest speed of the unit, which is crucial for evaluating equipment performance and ensuring safe operation.
3. Impact sub action monitoring: When the impact sub of the emergency governor "hits" or "retracts" due to centrifugal force during high-speed rotation, RZWW-03A can record the speed at which these actions occur and store this data in the instrument for users to view at any time.
4. Alarm function: When the speed exceeds the set alarm value, the device will light up through the alarm indicator light and output a switch signal on the rear panel to protect the monitored equipment. The alarm settings can be adjusted with a delay range of 1-60 seconds, which helps prevent false alarms caused by on-site interference.
5. Signal output: RZWW-03A is equipped with a current output interface, which can be connected to computers, DCS, PLC systems, paperless recorders and other equipment to achieve remote monitoring and recording of data.
6. Power off detection function: This device has power on and power off detection functions, as well as sensor disconnection detection function. When power failure or sensor disconnection is detected, the alarm and shutdown output circuits will be automatically cut off, effectively suppressing instrument false alarms and ensuring the stable operation of the system.
7. Parameter setting and operation: Users can set and view parameters through the operation keys on the dashboard, including the maximum speed value, impact sub action speed value, alarm value, alarm delay, etc. The setting and adjustment of these parameters enable the device to better adapt to different working environments and requirements.
8. Adapt to multiple sensor inputs: RZWW-03A can receive signals from reluctance speed sensors or gear sensors, which enables it to adapt to different measurement needs and on-site conditions.
9. High precision measurement: The display accuracy of this device can reach 1rpm, ensuring the accuracy and reliability of the measurement results.
10. Environmental adaptability: RZWW-03A can operate normally within a temperature range of -10 ° C to 65 ° C, with a storage temperature range of -10 ° C to -70 ° C and a relative humidity between 20% and 90% (non condensing), which enables it to operate stably under various environmental conditions.
