Pump body is the center of the pump structure, also known as the volute or pump casing, its type is also more. 1, the horizontal split type This type of pump casing is split on the horizontal split through the axis of the surface, the demolition of the pump casing with suction, the discharge pipe has nothing to do, maintenance is more convenient. 2, vertical subdivision This type of pump housing is vertical axis of the vertical plane is divided, not easy to leak, but must be removed in the maintenance of imported pipelines, so maintenance as horizontal split pump casing convenient. 3, inclined split type pump casing of this type is sucked in from the front, above the discharge, the pump casing in the axial plane through the inclined surface, do not disassemble the suction and discharge pipes, only open the upper half of the pump housing Overhaul the interior. 4, barrel type This type of pump is made of the pump shell into a barrel, the pressure is very high pump, with a single pump hard to withstand the pressure, so the double pump. Cylinder-type pump casing to withstand higher pressures, the installation of its horizontal split or vertical split rotor, fertilizer plant in the high-pressure boiler feed pump is mostly cylindrical multi-stage centrifugal pump. If the shell according to the type of support can be divided into the standard support type, the center of support, cantilever, pipe, hanging. 1, the standard support type This type of pump, generally horizontal, with legs on both sides of the pump body, the legs bolted to the base. 2, the center-supported type of this type of pump, pump housing on the underside of the feet installed on the base, can accommodate the transport of high-temperature fluid caused by thermal expansion stress. 3, this type of cantilever pump, pump housing is a whole, and the pump body and inhalation cover assembly mounted on the bearing bracket. Compact structure, easy to disassemble. 4, pipe type This type of pump is connected with the pipe as part of the pipeline together, and by the pipeline support. During maintenance, the pump's rotor and motor can be overhauled without removing the pump body connected to the pipe. 5, hanging This type of pump is installed in the discharge pump casing, the pump casing in the discharge pipe suspended below the suction container, the pump casing is vertically split type.
