Abstract
A kind of sheeting pump shell of centrifugal pump which includes a main shell, a vane wheel, an inlet dual-flange and an outlet by dual-flange. The main shell has the inlet and outlet to connect the inlet and outlet dual-flange. The rim of inlet dual-flange has an extended skirt structure to be mounted the location far away from the inlet dual-flange and the outlet dual-flange also has the skirt structure to connect with the main body and inlet dual-flange to improve the structural strength and the borne external force of the flange can be dispersed by the skirt structure. There is a special deflection in the main body which can form a pump shell volute in the pump shell with gradually increased section. By at least one roller to press the sheets for manufacturing that the metal plate can be gradually generated plastic deformation to form the pump shell body including the inlet end plate, volute end plate and the neck. Because the sheet pressing process is slow and gradually processing that the machining stress will not concentrate in a certain part.
