The plastic impeller modular construction of the utility model Submersible Pump, it is characterised in that: the modeling of Submersible Pump
Expect impeller assembly, by: three front shroud of impeller, back shroud of impeller and impeller upper cover plate parts form；It is set on cover board before the impeller
There is choma, back shroud of impeller is equipped with wheel hub and 4 ~ 8 blades, the bottom of blade are a plane or an arc surface, circle on back shroud of impeller
It is laid with gap identical with blade quantity week, welding energy line I is arranged in circumference uniform distribution on blade, and welding energy line I is set
It sets on blade；Circumference uniform distribution is equipped with boss on impeller upper cover plate, and the quantity of boss is identical as blade quantity, chamfered shape
It is identical as the shape of gap in setting after the impeller cover board, welding energy is laid in the groove inner periphery of impeller upper cover plate
Line II；Impeller upper cover plate is connected into the back shroud component for the form of being integrally formed, back shroud portion with back shroud of impeller by supersonic welding
Part is connected into impeller assembly by supersonic welding with front shroud of impeller.
The plastic impeller modular construction of the utility model Submersible Pump, with designing, reasonable, structure is simple, mold system
The characteristics of making convenient, achievable a multi-cavity mold, being readily produced, improves production efficiency, reduces manufacturing cost；And due to realizing
The injection molding production of the twisted blade of lesser blade and stream interface angle, for low cost, the design and life of high efficiency injection molding impeller
Production provides necessary condition.
