Question: What is the function of the turbine thrust bearing in an (DMTO) olefin separation unit? The function of the thrust bearing is to withstand the axial thrust exerted on the rotor by the steam, to determine the rotor’s axial position within the cylinder, and to restrict the axial movement of the rotor, thereby ensuring that the axial clearance between the moving and stationary parts in the flow path remains within specified limits! Note: The answers will be announced automatically in two days!
It withstands the axial thrust on both the positive and negative sides of the rotor, and serves as a positioning dead point for the rotor. It maintains the axial relative position between the rotor and the cylinder during expansion. By adjusting the total gap between the working and non-working bearing pads and the rotor’s thrust disc (i.e., the thrust clearance), it determines the amount of axial movement of the rotor, ensuring that the rotor has a certain range of axial movement under any operating conditions

The function of the thrust bearing is to bear the axial thrust on the rotor during operation, and to determine and maintain the axial alignment between the turbine rotor and the cylinder
The function of the thrust bearing is to withstand the axial thrust exerted on the rotor during operation, and to determine and maintain the axial relative position between the turbine rotor and the cylinder. Thrust bearings can be designed as separate units, or they can be combined with support bearings to form a single unit, known as a combined type (thrust-support combined bearing). Based on their structural shape, they can be divided into multi-jaw types and fan-shaped tile types; the fan-shaped tile type is the one that is commonly used nowadays. The main structure consists of working tiles, non-working tiles, adjustment shims, mounting rings, etc. 10 to 12 working tiles and non-working tiles are installed on each side of the thrust disc. Each tile is mounted on a mounting ring; the working tiles bear the forward axial thrust of the rotor, while the non-working tiles bear the reverse axial thrust of the rotor. The distance that the thrust disc moves between the working tiles and the non-working tiles is called the thrust gap, which is generally not more than 0.4 mm. The thickness of the black iron on the tiles is generally 1.5 mm, a value that is less than the minimum clearance between the moving and stationary parts of the turbine, ensuring that these parts do not rub against each other even in the event that the black iron melts.
