The water turbine shear pin annunciator CJX-14 is a device installed on the guide vane shear pin. The main function of the shear pin annunciator is to monitor the integrity of the shear pin and provide immediate feedback when the shear pin breaks. This allows the operator to take immediate measures to prevent further damage or accidents. The shear pin annunciator is integrated with the control instrument to better monitor and manage the operating status of the turbine.

The shear annunciator CJX-14 is made of high quality brittle polystyrene material, organic glass, etc. It can trigger the action of annunciator in case of stress or fracture. Its material has excellent mechanical property, impact resistance and transparency, which can ensure that the annunciator has good durability and visibility while not hindering its functionality.

CJX-14 annunciator is simple in structure. Its working principle is that when the shear pin breaks for some reason, the annunciator will trigger an alarm through its internal mechanical or electronic mechanism. This signal can be transmitted to the central control room or operator through the monitoring system, so as to ensure timely response.

The specific working mode is as follows:

The normally closed annunciator CJX-14 is in direct contact with the shear pin. When the shear pin is not broken, the sensor is in a normal state and no signal is generated. Once the shear pin breaks, the state of the sensor changes, usually due to the displacement or breakage of the shear pin. The state change of the sensor will be converted into electrical signal. After being processed by the circuit, the alarm system will be triggered, such as sending sound and light alarm or sending signal to the monitoring system through the communication interface.

There are different types of sensors used for different steam turbine units. Check if it has the sensor you need, or contact us for more details.
