Description
Technical field
The utility model relates to the metallurgical casting technical field, especially a kind of magnesium alloy pouring pump.
Background technology
Extensive use with various alloy materials, the deep processing problem of magnesium alloy is put on agenda, because the technical equipment of magnesium alloy fusing, cast is relatively backward, cause casting quality to be difficult to improve, in addition, active and the easy oxidizing fire of magnesium alloy high temeperature chemistry character, there have slightly to be improper, and security incident just easily takes place.At present, during magnesium alloy pouring, the pump housing of employing is vane pump, screw pump or centrifugal pump, and its course of work all is by pump liquation to be aspirated the process of lifting from bottom to top, and there is following defective in this mode when being used for magnesium alloy pouring; 1., water the fluence instability, the value that promotes liquation by the pump suction directly is subjected to the influence of melt temperature, liquid level, causes that to water fluence wayward, the material consumption increases; 2., the bits in the liquation are not easily separated, pump sucks the bits in the liquation in aspiration procedure easily, causes that pipeline blocks, workpiece produces slag inclusion; 3., existing pouring pump have that processing safety is poor, maintaining difficulty, problem that maintenance cost is high.
Summary of the invention
The purpose of this utility model is a kind of magnesium alloy pouring pump that provides at the deficiencies in the prior art, and it is pressed into the hydrojet pipeline from bottom to top with liquation and pours into a mould, and fluid speed is fast, and the duration of pouring is short, stability of flow, and slag of the no end sucks.
The concrete technical scheme that realizes the utility model purpose is:
A kind of magnesium alloy pouring pump, comprise workbench, connecting rod, the pump housing, workbench is provided with the motor bearing, the motor bearing is provided with motor, the pump housing is located at the workbench bottom and is fixedlyed connected through several support bars with workbench, the pump housing is provided with the hydrojet pipeline, and the hydrojet pipe outlet stretches out workbench, is provided with shaft flow rotor in the pump housing; Connecting rod passes workbench and an end connects shaft flow rotor, the other end connects motor output shaft.
The described pump housing is one spoonful of shell body, and head is established a cylindrical cavity, is provided with runner in the shank, and runner is communicated with cavity, and shaft flow rotor is located in the cavity, and the hydrojet pipeline is communicated with runner, and pump housing bottom and corresponding cavity place are provided with Yu Yifa.
Described shaft flow rotor is two concentric circles column casings that diameter is different, is provided with several blades between its two external diameter and the internal diameter, and great circle column casing external diameter is provided with groove.
The utlity model has that fluid speed is fast, the duration of pouring is short, stability of flow, advantages such as slag suction of the no end, and simple in structure, low cost of manufacture, safe and reliable, be convenient to maintaining.
