Embodiment 1

[0020] A low-temperature motor magnetic material for a submersible liquefied natural gas pump, which contains 28% MgB 2 And 12% of SmCo, the balance of VM111-35N silicon steel.

[0021] According to the conventional method, it is prepared as a low-temperature motor magnetic material for a submersible liquefied natural gas pump. After testing, it can work normally at -260°C, and the iron consumption at low temperature is basically the same as that at normal temperature.

Embodiment 2

[0023] A low-temperature motor magnetic conduction material for a submersible liquefied natural gas pump, which contains 15% MgB 2 And 18% of SmCo, the balance of VM111-35N silicon steel.

[0024] According to the conventional method, it is prepared as a low-temperature motor magnetic material for a submersible liquefied natural gas pump. After testing, it can work normally at -280°C, and the iron consumption at low temperature is basically the same as that at normal temperature.

Embodiment 3

[0026] A low-temperature motor magnetic material for a submersible liquefied natural gas pump, which contains 13% MgB 2 And 15% of SmCo, the balance of VM111-35N silicon steel.

Abstract

The invention discloses a low-temperature motor magnetic-conducting material for a submerged liquefied natural gas pump. The material takes silicon steel as a main body and is doped with MgB2 and SmCo. The working temperature of the motor magnetic-conducting material can reach -250 DEG C and below, and the advanced level in the field is achieved.

Description

technical field [0001] The invention relates to the field of motor materials, in particular to a low-temperature motor magnetic conduction material for a submersible liquefied natural gas pump. Background technique [0002] At present, with the aggravation of air pollution, especially smog pollution, there are more and more restrictions on fuels with high dust, sulfur and nitrogen content, especially coal fuels. However, the demand for fuel in the entire northern region is increasing, so the application of clean energy will become wider and wider. [0003] In clean energy, natural gas has been widely used because of its high calorific value, convenient transportation and only carbon dioxide and water produced after combustion. A large number of applications of natural gas have brought corresponding transportation problems, and because of its form, natural gas is mainly transported through liquefaction. When the delivery volume of liquefied natural gas (LNG) is relatively l...
