    摘要： A dual-sided impeller for a centrifugal blower assembly is provided. The dual-sided impeller comprises a plurality of fan ribs defined in a single continuous metal sheet and extending from a hub toward a circumference of the impeller. Each of the plurality of fan ribs has first and second vanes, wherein the first and second vanes extend in opposing directions relative to a plate region of the impeller. The first and second vanes can comprise one or more of a forward-curved vane, a backward-curved vane, a forward-inclined vane, a backward-inclined vane, and a radial vane. The centrifugal blower assembly comprises a blower housing, wherein the dual-sided impeller is disposed within the blower housing. The dual-sided impeller is continuous and is stamped and/or pressed from a single sheet of metal, such as one or more of a sheet of steel, stainless steel, and aluminum.

    摘要： A food centrifugal pump formed by stamping and welding, comprising a pump casing and a cover mounted therein, an impeller, a shaft and a motor provided on the outer side of the casing, wherein the impeller is mounted on the shaft and driven to rotate by the motor; the pump casing is provided with an inlet pipe and an outlet pipe; the impeller have a structure of half-opened type and consists of blades, a hub and a back cover plate, the front end of the blade is close to the inner side of the axial plane of the pump casing, and there is an end face seal formed therebetween; the pump casing is formed by stamping a single metal plate, the outer side of the axial plane of which is provided with an inlet pipe bracket used to support the inlet pipe, the end of which is connected to the outer side of the pump casing, the other end of which is nestedly connected to the inlet pipe and fixed thereon. The manufacturing process of the food centrifugal pump is simple and convenient, its cost is low, its flow rate capability is high, and the inside of the pump casing is clean.
