Its main function is to collect the liquid thrown by the inner impeller, and at the same time convert part of the kinetic energy of the high-speed liquid into static pressure energy. The shape of the pump shell is usually volute-shaped. This design makes the cross-section of the flow channel gradually increase, the speed decrease, and the pressure increase, thus realizing the conversion of kinetic energy. The casting of the pump shell casting is to pour the molten metal into the inner part of the shell mold to ensure that the molten metal can evenly and smoothly fill the cavity of the shell mold, and then wait for cooling to remove the mold.
