Magnesium alloy pouring pump

Abstract

The invention discloses a magnesium alloy casting pump, which includes a workbench, a connecting rod and a pump body; wherein, the workbench is provided with a motor bearing which is provided with an electric motor; the pump body is arranged under the workbench and is fixedly connected with the workbench through a plurality of supporting bars; the pump body is provided with a liquid-spraying pipeline, the outlet of the liquid-spraying pipeline extends out of the workbench; the pump body is internally provided with an axial rotor; the connecting bar penetrates through the workbench, and one end of the connecting bar is connected with the axial rotor, while the other end of the connecting bar is connected with the output shaft of the motor. The magnesium alloy casting pump provided by the invention has the advantages of high speed of liquid output, short pouring time, stable flow, no inhalation of residue dregs, besides, the magnesium alloy casting pump has the advantages of simple structure, low manufacturing cost, safety and reliability, and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of metallurgical casting, in particular to a magnesium alloy pouring pump. Background technique [0002] With the wide application of various alloy materials, the deep processing of magnesium alloys has been put on the agenda. Due to the relatively backward technical equipment for melting and pouring of magnesium alloys, it is difficult to improve the quality of castings. In addition, the high-temperature chemical properties of magnesium alloys are active and easy to oxidize and burn. , A little improper, it is prone to safety accidents. At present, when magnesium alloy is poured, the pump body used is an impeller pump, screw pump or centrifugal pump. The working process of the pump is to pump the melt from bottom to top. This method has the following problems when magnesium alloy is poured: Defects; ①, the pouring amount is unstable, and the value of the melt is directly affected by the temperature and liq...

[0002] With the wide application of various alloy materials, the deep processing of magnesium alloys has been put on the agenda. Due to the relatively backward technical equipment for melting and pouring of magnesium alloys, it is difficult to improve the quality of castings.

At present, when magnesium alloy is poured, the pump body used is an impeller pump, screw pump or centrifugal pump. The working process of the pump is to pump the melt from bottom to top. This method has the following problems when magnesium alloy is poured: Defects; ①, the pouring amount is unstable, and the value of the melt is directly affected by the temperature and liquid level of the melt through pumping, resulting in difficult control of the pouring amount and increased material consumption; ②, the slag in the melt is not easy to separate, The pump is easy to suck the slag in the melt during the pumping process, resulting in blocked pipes and slag inclusions in the workpiece; ③, the existing pouring pumps have the problems of poor operation safety, difficult maintenance, and high repair costs
