Why does the rudder angle indicator deviate too much?

The rudder angle indicator is an indispensable equipment in the steering gear, and the rudder equipment is used to stabilize the course and turn of the ship. Generally, ships need to install three rudder angle indicators, which are directly in front of the cockpit rudder platform and the two wing feet outside the cabin. The normal operation of the rudder angle indicator is very important to the safety of the heading. Therefore, when the rudder angle indicator deviation is too large, it is necessary to find out the cause and solve it in time.

     The 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 the rudder hardware problem is very small. Generally, the feedback link of the rudder angle, the signal link of the given rudder angle, and the link of the amplifying device are considered. If none of these links fails, then consider the hardware problem of the steering gear. According to this kind of thinking, we will investigate and solve the problem step by step.

     If the navigation time is too long, the rudder equipment is prone to failure, which will also affect the accuracy of the rudder angle indicator. Therefore, after the rudder equipment has been used for a period of time, it must be returned to the factory for re-debugging.
