Aux 1 Unit 9 Q7

Correct Answer: B) To transmit the steering command from the bridge to the steering gear via hydraulic pressure

Explanation: The primary function of a hydraulic telemotor system is to transmit steering commands from the ship's bridge to the steering gear using hydraulic pressure, ensuring accurate and responsive steering control.

Correct Answer: C) By varying the hydraulic pressure in the control lines connected to the steering gear

Explanation: The hydraulic telemotor system transmits steering commands by varying the hydraulic pressure in the control lines. These pressure changes correspond to the helm’s movement, which is then transmitted to the steering gear to move the rudder.

Correct Answer: B) To convert the mechanical movement of the helm into hydraulic pressure changes

Explanation: The transmitter unit in a hydraulic telemotor system converts the mechanical movement of the helm into hydraulic pressure changes. These pressure changes are then sent through the hydraulic lines to the receiver unit, which operates the steering gear.

Correct Answer: B) The receiver unit

Explanation: The receiver unit in the hydraulic telemotor system responds to the pressure changes transmitted by the helm. It converts these pressure signals back into mechanical movement to actuate the steering gear and move the rudder.

Correct Answer: B) The pressure in the starboard control line increases, causing the rudder to move to starboard.

Explanation: When the helm is turned to starboard, the hydraulic pressure in the starboard control line increases, which causes the receiver unit to move the rudder to starboard. The hydraulic system ensures that the movement of the rudder corresponds directly to the helm's commands.

Correct Answer: B) To provide real-time information to the helm about the rudder's position, allowing for accurate adjustments

Explanation: The feedback mechanism provides real-time information about the rudder's position to the helm, ensuring that the operator can make accurate adjustments to maintain the desired course.

Correct Answer: B) To equalize the hydraulic pressure between the port and starboard control lines, ensuring smooth operation

Explanation: The balance pipe in a hydraulic telemotor system equalizes the hydraulic pressure between the port and starboard control lines, ensuring that the system operates smoothly and that the rudder responds accurately to the helm's movements.

Correct Answer: B) The system could experience reduced efficiency, leading to sluggish or inaccurate steering responses.

Explanation: Contaminated hydraulic fluid can reduce the efficiency of the telemotor system, leading to sluggish or inaccurate steering responses. Contamination can cause blockages, increased wear, and potential system failures.

Correct Answer: C) By the movement of the helm, which is mechanically linked to the transmitter unit

Explanation: Hydraulic fluid pressure in a telemotor system is generated by the movement of the helm, which is mechanically linked to the transmitter unit. This unit converts the mechanical motion into hydraulic pressure, which is then transmitted to the receiver unit.

Correct Answer: A) Regularly checking and maintaining the hydraulic fluid levels and quality

Explanation: Regularly checking and maintaining the hydraulic fluid levels and quality is essential for the reliable operation of the telemotor system. Proper maintenance helps prevent contamination, leaks, and pressure loss, ensuring the system operates smoothly and accurately.
