Stainless Steel Open Impeller

The stainless steel open impeller refers to the wheel with the bucket and is part of the impeller of the impeller. Also it refers to the general name of the wheel and the rotating blades mounted thereon.
The stainless steel open impeller has only vanes and blade stiffeners, and the impeller without front and rear covers (the number of open impeller blades is 2-5). The impeller has low efficiency and low application, and is mainly used for conveying liquid with high viscosity and slurry liquid. The blades of the centrifugal pump impeller are generally back-bent blades. The blade has two kinds of cylindrical and twisted shapes. The application of the twisted blade can reduce the load of the blade, improve the suction performance of the centrifugal pump, and improve the anti-cavitation capability, but it is difficult to manufacture and has a high cost. The centrifugal pump for refining and chemical engineering requires the impeller to be an integral impeller for casting or full weld welding. The welding impeller has been developed and is used in special centrifugal pumps for chemical industry made of poorly cast metal materials such as iron and its alloys. The geometric precision and surface finish of the welding impeller are better than the casting impeller, which is beneficial to improve the efficiency of the centrifugal pump.
