How do you adjust a thruster brake?
To adjust the braking torque to the desired value, the preloading of the compression spring is to be done by top nuts up the spring tie rod. To increase torque, turn nuts clockwise. The adjustment of the braking torque is very critical.
What is a thruster brake?
Thruster brakes are fail-safe brakes that are spring applied and use an electrohydraulic thruster to hold the brake open. When supplied power, the thruster piston rod extends and the brake is released. If the thruster is turned off or power is lost, the piston rod retracts and the spring engages the brake.
How does a hydraulic thruster work?
Thruster is an electro hydraulic device, designed to exert a constant force to any mechanism to be operated. The Thruster works on a principle of hydraulics. On supply of electric power, motor driven centrifugal impeller draws the oil from the low pressure end of the chamber to the high pressure upper end.
Which oil is used in thruster brake?
Requires Transformer Oil to be filled in the thruster cylinder. Function is to bring to stop, moving / rotating machinery like motor / gearbox.
What is DCEM brake?
DC Electro-Magnetic shoe brakes are actuated by an energy stored in the compression spring and is released by a DC electromagnet. Thus , the brake is fail-safe and is normally (applied). The DC magnet coil, when energized releases the brake. These brakes are characterized by robust construction and design.
How does an electromagnetic brake work?
An electromagnetic brake uses an electric actuation but transmits torque mechanically. When the brake receives voltage or current, the coil is energized, creating a magnetic field. This field turns the coil into an electromagnet that creates magnetic lines of flux. The magnetic flux attracts the armature.
What is thruster capacity?
Drum Diameter: Up to 600 mm drum diameter. Voltage: AC Supply,400 / 440 Volts,3 Phase,50 C/s. Oil Capacity: 2.0 Literes.
What are thrusters used for?
Thruster is a propulsive device used by spacecraft for station keeping, altitude control, in the reaction control system, or long-duration, low-thrust acceleration.
How do bow thruster work?
The addition of bow thrusters allows a boat to move to the side (port or starboard) without forward or backward thrust from the engine or rudder. Thrusters use suction to draw in water from one side of the boat and push it out the other side to move the boat in the opposite direction.
What is electro hydraulic thruster brake?
Electro Hydraulic Thruster Brake is used to retard the speed of moving machinery and to stop it accurately to the desired position. The breaking force is applied to the brake shoes by a pre—stressed compression spring. The brake shoes press on the rotating brake drum retarding its speed, and finally stopping it.
