Description

technical field [0001] The invention relates to the technical field of centrifugal pump casing production, in particular to a casting molding system for a multistage centrifugal pump casing. Background technique [0002] Centrifugal pump casings are often produced by casting to form a complete whole with good sealing performance and are relatively popular. However, the existing casting and forming systems are prone to local condensation during casting or transfer. , affecting the casting effect and casting efficiency; in addition, after casting, the cooling molding speed is slow, and the production efficiency of the centrifugal pump shell is not high. Contents of the invention [0003] The object of the present invention is to provide a multi-stage centrifugal pump casing casting molding system to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical sol...
