What is the balance hole on the impeller of the steam turbine?
Although theoretically speaking, there is no pressure drop on the moving blade of the steam turbine, but because of the leakage of the steam seal of the partition plate, the impeller will produce a certain pressure difference between the front and rear of the impeller, which will cause axial thrust to increase. After the impeller is balanced, it can reduce the axial thrust.
Steam turbine. The utility model is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors, ships, propellers, etc.. The utility model can also utilize the exhaust steam or the middle exhaust steam of a steam turbine to meet the heating requirements of production and life.
Can play a role in reducing axial thrust.A steam turbine is a rotating power machine that converts the energy of steam into mechanical work
