The discharge section area of the design welding stator is equal to the average discharge section area, according to the axial plane of the casting stator
Projection determines the axis plane projection of the welding stator；The design welding stator includes the first plane domain, the second plane domain
And the cylindrical surface areas between first plane domain and second plane domain, ensureing the import of welding stator
On the premise of angle, the angle of outlet and cornerite are respectively equal to inlet angle, the angle of outlet and the cornerite of the casting stator, according to the casting
Make stator leaf adjustment it is described welding stator it is leaf.Such scheme is complicated, and also fails to solve stator and impeller wiping
The technical problem in jail.
