It is segmented into import 51 and outlet 52；The import 51 is connected with the first chamber 12；The outlet 52 and second cavity volume 21
Connection.
The technique that the manufacture of the present embodiment water chamber head-pump case integral structure can be combined by " forging+machining "
Realize.Concrete mode is first solid forging shaping, the internal chamber passage that can not be directly realized by for forging, by being machined to
Type.The main manufacturing process of water chamber head solid forging is：Smelting ingot casting → forging → heat treatment after forging → roughing → ultrasound
Ripple detection → property heat treatment → machining sampling → inspection (chemical composition, mechanical performance, metal lographic examination etc.) → machining →
Non-Destructive Testing.Pump case chamber, pump case chamber outlet runner are then machined out shaping.Finally again by hydroecium dividing plate and turnover
Mouth ozzle dividing plate is connected by welding with water chamber head solid forging respectively.
