press plate China Manufactory custom material sealing press plate for steam turbine use

During the starting and loading process of steam turbine, the temperature of cylinder changes greatly, so the thermal expansion value is large. In order to ensure that the cylinder can expand freely in the given direction when it is heated, and keep the center of the cylinder and the rotor consistent. Similarly, when the steam turbine is shut down, the cylinder can contract freely in the given direction. A series of guide sliding pins are set between the inner and outer cylinders, between the cylinder and the bearing block, between the bearing seat and the platen, forming the sliding pin system of the steam turbine. It mainly includes: vertical pin, horizontal pin, longitudinal pin, cat scratch cross pin, angle pin (pressure plate), etc.
