china indicator rudder angle
Our China rudder angle indicator can bu used on different kinds of marine , boat and yacht. When the ship is advancing at full speed (111 rpm), turn the rudder angle indicator from 35 ° on one side to 35 ° on the other side, and it should be able to turn from 35 ° on one side to 30 ° on the other side within 28 seconds. When the ship is advancing at half speed (56 rpm) and the speed is not less than 7 knots, make the rudder angle indicator switch from 15 ° on one side to 15 ° on the other side within 60 seconds and move flexibly. Throughout the entire test process, the hydraulic system and all moving components should have no abnormal heating/vibration/knocking/oil leakage, and the speed/oil pressure/oil temperature/viscosity of the oil pump and ship speed data should be recorded, meeting the requirements of the manual. Collision stop reverse test: (only for the first ship, the process is about 20 minutes) When the main engine is sailing at maximum speed, pull the handle of the car clock from "NAV. FULL AHEAD" (main engine speed is 107 rpm) to the "CRASH ASTRN" (main engine speed is 80 rpm) position on the bridge until the ship stops completely. Observe and record the time and speed/heading/wind speed/wind speed of the main engine at various points during this process, such as camshaft commutation/brake start air/start air cut-off/full speed reverse.
What is the difference of ± 0.5 ° in the following rudder degrees from the three rudder angles; ±1°。 When aligning the rudder, the error of the china rudder angle indicator indicating the position of the rudder blade deviation should not exceed ± 1 °; ± 1 °, and the error should be. ± 0.5 ° when facing the rudder; ±1°。 When the error between the rudder angle command on the steering instrument and the actual rudder angle exceeds ± 1 °, adjustments need to be made. The transmitter and signal amplifier have high accuracy and rarely malfunction, and can be directly debugged in the system. The entire system is powered on, the rudder angle of the servo is placed in position, the top cover of the rudder angle transmitter is opened, the three screws fixing the rotating shaft are loosened (do not need to be removed), and the rotating shaft is adjusted to indicate 0 ° on the china rudder angle indicator gauge.
