The difference between energy-saving stator and guide wheel in ships

The difference between energy-saving stator and guide wheel in ships

The stator is one of the main components of a ship's AC motor, which generates a magnetic field through a fixed winding, thereby inducing electromotive force on the rotor. On ships, the main function of the stator is to convert electrical energy into mechanical energy, driving the ship forward. The energy-saving design of stator mainly includes two aspects: first, reducing stator resistance loss, and second, reducing stator iron loss. These measures include using low resistance materials to manufacture the stator, increasing the conductivity of the stator winding, and reducing the cross-sectional area of the winding.

What is the difference between the front guide wheel and the rear guide wheel of a ship's pump jet propulsion system?

What is the difference between the front guide wheel and the rear guide wheel of a ship's pump jet propulsion system?

The pump jet thruster of a ship is commonly referred to as a water jet thruster, but due to the widespread use of shaftless pump propulsion in submarines in China, many people believe that the pump jet thruster is the thruster of submarines.

Grinding of spiral guide wheels

Grinding of spiral guide wheels

Due to limitations, traditional guide wheel grinding machines are commonly used for convex spiral guide wheels, which rely on templates for grinding. Due to errors in template production, assembly errors in installing templates onto the guide wheel grinder, and errors in the guide wheel grinder itself, errors may accumulate, resulting in significant deviations between the final result of guide wheel grinding and the design.

Design of guide wheel system for multi wire cutting machine

Design of guide wheel system for multi wire cutting machine

The guide wheel system is responsible for the transmission and direction change of metal wires in the multi wire cutting machine. The wire speed of the multi wire cutting machine can reach up to 680 m/min, and the corresponding guide wheel speed is nearly 3000 r/min. This requires the guide wheel system to rotate at high speed and flexibly, with small jumping, high reliability, and long service life, to ensure stable tension of the metal wire and overall reliability of the equipment. At the same time, the guide wheel system is all located on one side of the winding box, in a relatively dirty working environment, and the mortar fluid will inevitably adhere to the guide wheel. To ensure the flexibility of the guide wheel rotation, a sealing device must be designed for the guide wheel. The entire guide wheel system is mainly composed of components such as spacers, guide wheel shafts, guide wheels, pressure covers, bearings, etc. The guide wheel is the embodiment of accuracy in the entire system. The metal wire moves at high speed in the guide wheel groove, driving the guide wheel system to move at high speed. The rotational accuracy of the guide wheel reflects the accuracy of the entire system. Therefore, the entire system must ensure the rotational accuracy of the guide wheel after installation, including rotational flexibility, end jumping, and radial jumping accuracy. The high-precision angular contact ball bearings used back-to-back ensure the rotational accuracy of the guide wheel system, making it high-precision and long-life, Small end jumps and radial jumps.
