Why Is The Rudder Angle Indicator Too Large?

The rudder angle indicator is an indispensable device in the steering gear, and the rudder device is used to stabilize the ship's heading and rotation. In general, three rudder angle indicators are required for the ship, which are the front of the cockpit and the two wings of the cabin. The normal operation of the rudder angle indicator is very important for heading safety. Therefore, when the deviation of the rudder angle indicator is too large, it is necessary to find out the cause and solve it in time.

     Excessive deviation of the rudder angle indicator is mainly affected by the control link and the feedback link. Generally, the deviation of the rudder angle indicator is too large, and the possibility of problems in the steering gear hardware is very small. Generally, the feedback link of the rudder angle, the rudder angle signal link, and the amplification device link are considered. If there is no fault in these links, consider the hardware problem of the servo. According to this line of thinking, gradually check and solve the problem.

     If the sailing time is too long, the rudder equipment is prone to failure and will affect the accuracy of the rudder angle indicator. Therefore, after using the rudder equipment for a period of time, it is necessary to take it back to the factory for re-commissioning.
