Abstract

The invention discloses a pump for conveying high temperature molten aluminum. The pump comprises a stator. A high temperature molten aluminum outlet is formed in the outer wall of the front part of the stator, a high temperature molten aluminum inlet is formed in the outer wall of the back part of the stator, a rotor coaxially arranged with the stator is arranged in the stator, a gap is formed between the rotor and the stator, threads same in structure and opposite in rotating direction are arranged on the outer wall of the rotor and the inner wall of the stator, and spiral chutes of the threads are right-angled triangular spiral chutes; the back end and the front part of the rotor are rotatably connected to the stator, a front end cover and a back end cover are separately fixed to the front end and the back end of the stator, the headmost end of the rotor penetrates the front end cover, and the headmost end of the rotor can be connected to a driving device which drives the rotor to rotate around the axis of the rotor. The pump is simpler in structure and more practical, can guarantee the coaxiality of the stator and the rotor better, can exert better performance and is more suitable for a working environment.

Description

technical field [0001] The invention relates to a pump, in particular to a pump for transporting high-temperature aluminum liquid. Background technique [0002] The existing automobile wheel hub casting process is low-pressure casting. During the die-casting process, the air intake pipe is inflated and pressurized for die-casting, and the entire mold is basically sealed. The speed of filling the aluminum alloy liquid is relatively fast, and the gas cannot be discharged in time It will cause groups of small air holes inside the aluminum alloy wheel hub. In addition, during the process of holding the pressure until it is completely solidified, a concave air pocket will be formed on the surface of the aluminum alloy hub, and these small air holes and air pockets will have a greater impact on the performance of the aluminum alloy wheel hub. In addition, the riser pipe is in contact with the high-temperature aluminum alloy liquid for a long time, and the service life is short and...
