The closed impeller belongs to Gas Industry Equipment Precision Steel Castings. It is a centrifugal impeller with a wheel and a wheel cover. It is used in a fixed centrifugal compressor. There is no undercurrent loss at the top of the blade, and the efficiency is high, but the stress of the wheel cover is large, and the peripheral speed is limited, generally less than or equal to 320 nsI.
According to the blade bending form, it is divided into a rear curved blade impeller, a radial blade impeller and a front curved blade type juice wheel.
According to the manufacturing method, there are riveting, milling, welding, brazing, precision casting and electro-erosion addition.

This Gas Industry Equipment Precision Steel Castings is a closed impeller consisting of front and rear covers and blades. The efficiency of the closed impeller is high, but the impeller clearance is called narrow pass, but impurities, especially the impeller of a small centrifugal pump requires that the medium to be transported is clearer, the viscosity is not large, and the fiber material cannot be contained. At present, most centrifugal pumps still use the impeller, such as ISG pipe centrifugal pump, ISW horizontal centrifugal pump, and the like.
