What is an adjustable torque propeller?

An adjustable torque propeller is a type of propeller that can adjust torque and is commonly used in Marine propulsion systems. The propeller can change the propulsion force and speed of the ship by adjusting the torque according to different sailing requirements and working conditions.

The adjustable torque propeller is usually composed of five major components or systems, such as blade, hub mechanism, oil distributor, hydraulic system and electronic remote control system. Operating the control lever in the cab, the electro-hydraulic servo control system through the oil distribution mechanism, the direction and the amount of oil are controlled by the high-pressure oil into the servo cylinder located in the propeller hub, and through the rotor mechanism, drive the blade, in the full ahead and full astern range, stepless adjustment of pitch Angle. For any defined pitch Angle, a propeller driven by the main engine operating at a certain speed converts the absorbed torque into a force pushing the boat forward or pulling the boat backward.

Adjustable torque propeller has the following advantages:

• Energy saving and environmental protection: Adjustable torque propeller can adjust the propulsion force according to the actual demand, avoid energy waste, while reducing emissions, which is conducive to environmental protection.

• Improve efficiency: By adjusting the torque, the adjustable torque propeller can adapt to different navigation needs and working conditions, and improve the propulsion efficiency and navigation efficiency of the ship.

• Extended life: Adjustable torque propellers reduce wear and stress on the propulsion system and extend service life.

• Reduce maintenance costs: The design of adjustable torque propellers can reduce the frequency and complexity of maintenance and repair, reducing maintenance costs.
