Air-cooled type aluminium pad permanent magnet pump

Abstract

The invention discloses an air cooled molten aluminum permanent magnetic pump, which comprises an annular silicon carbide sealed pipeline. The annular silicon carbide sealed pipeline is arranged in a pump body and is provided with a heat insulating and isolating layer made of heat resisting materials; a main shaft is connected to a main motor and a transmission device thereof ; a permanent magnet fixed plate is connected with the main shaft; a permanent magnet is fixed on the permanent magnet fixed plate through a pure iron yoke embedded on the permanent magnet fixed plate and is arranged on upper side and the lower side of the sealed pipeline or one side or the inside thereof; an austenitic stainless steel pump body is provided with an inlet hole and an outlet hole which are used for the sealed pipeline to extend out of the pump body to be connected with the outside; a temperature sensor is arranged in the pump body; a forced cooling air system is arranged on the pump body; and a power distribution control system is connected with the main motor, the temperature sensor and the forced air cooling system. The permanent magnetic pump has the obvious advantages of high energy conservation, high efficiency, low cost, no pollution, low maintenance cost, long service life and reliable work.

Description

technical field [0001] The invention relates to a permanent magnet pump, in particular to provide an air-cooled aluminum water permanent pump used in the field of non-ferrous metal aluminum processing and suitable for controlling the directional flow of high-temperature aluminum metal melt in pipelines, smelting furnaces and holding furnaces. magnetic pump. Background technique [0002] In the field of non-ferrous metal processing, in order to improve the quality of aluminum alloy and reduce burning loss, various alloying elements should be added and mixed evenly during the smelting process. At present, there are many kinds of molten metal stirring equipment, among which the aluminum water pump is recognized as the best stirring device. It can make the molten aluminum move according to the designed direction and flow rate, so that the molten aluminum in the melting furnace can be fully and quickly mixed. [0003] There are two kinds of aluminum water pumps known in the wor...

Problems solved by technology

But they also have many disadvantages: the aluminum water electromagnetic pump is expensive, consumes more power, and its specially designed N-turn multi-layer combined electromagnetic induction coil needs to be cooled by liquid nitrogen or soft water circulation cooling system, and the control system of electric appliances is more complicated. , the auxiliary equipment occupies a large area and is easy to pollute, so it is rarely used in China at present

The aluminum water mechanical pump is a contact stirring device. Since it needs a complex protection system for the contact part with the high-temperature aluminum melt, it is easy to cause pollution to the aluminum liquid. The rotating impeller and the pump body are mostly immersed in SST grade graphite materials. In molten aluminum, it is very easy to wear and damage, so its service life is short and the annual maintenance cost is high. Many users can afford it and cannot afford it.
