High-Efficiency Underwater Thruster
All of our underwater thrusters are very efficient and are proven models that have a solid track of records. All underwater thrusters body are streamlined and limit flow blockage. Being of superior design, using Torque PMSM motors together with SK propeller and Rice Nozzle shape of the Lian Innovative underwater thruster keeps the efficiency as high as 42% at low-speed heavy loads. For high speed, light loads using high-speed Direct Drive PMSM motors combined with B-series propellers keeps efficiency up to 63%. The Efficiency has been calculated between input power (Dc voltage cross current) and output hydrodynamic power (Thruster force cross vehicle speed).
This high level of efficiency rated our underwater thrusters to be more attractive in the high-tech applications. As an ROV thruster, using Lian Innovative underwater thruster leads to using thinner umbilical which reduced the drag load and rises the system overall efficiency high. As AUV thruster and submarine thrusterو using Lian Innovative underwater thruster led to reduces the battery size and overall cost.
Advanced Shaft Sealing
All our underwater thrusters have a very advanced design triple redundant sealing system. The first seal is a high quality ceramic mechanical seal which is totally worn resistance. And two specially designed elastomer internal/external seal that is capable of sealing the motor on its own. This offers a large safety margin to prevent water leaks into the motor.
The multi-shaft sealing system design allows the ROV thruster and AUV thruster to continue running in the event of a shaft seal failure and subsequent flooding, without damage to the winding or electronic components.
Advanced System Design
Lian Innovative underwater thrusters provide the most reliable AUV thrusters and ROV thrusters currently in the marketplace. Lian Innovative underwater thrusters Electric Motor are direct drive and do not require any adapter shaft, extra bearings, gears and or a gear box. The ROV motors efficiently produce all the torque needed by the propeller without any gearbox. Lian Innovative’s new direct drive range of PMSM (brushless DC motor) thrusters breaks new ground in the underwater thruster, low weight, and enhanced reliability.
We have single and multi-channel controllers suitable for battery operated units. And for the larger underwater thruster which needs higher power, high voltage controllers are provided which generally will be fed by umbilical. The application is very dependent on your needs. Integrated electronic drives are matched with motors to produces the highest level of efficiency.
Lian Innovative AUV thrusters and ROV thrusters are currently available in many sizes, each incorporating Lian Innovative’s unique technology.
All of Lian Innovative underwater thruster independently tested for 12 hours under highest water pressure and variable load to ensure the finalized product quality. All of our product are guaranteed for one year.
