Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a filtering device used for a vacuum turbine pipeline. Background Art

[0002] A turbine converts the energy contained in a fluid into mechanical work. While turbines vary in their operating conditions and fluids, their structures differ, all share a common principle. The most important component of a turbine is a rotating rotor, or impeller, mounted on the turbine shaft and featuring evenly spaced blades. The energy of the fluid is converted into work as it passes through the nozzle. As it flows through the impeller, the fluid impacts the impeller, driving it to rotate, thereby driving the turbine shaft and producing mechanical work.

[0003] During the operation of the turbine, some impurity particles in the pipeline enter the turbine, which will accelerate the wear of the impeller inside the turbine and sometimes cause the turbine to get stuck, resulting in a decrease in vacuum, a slowdown in pumping speed, and a reduction in the service life of the turbine.
