Problems solved by technology

[0003] At present, most of the marine motor shell market is welded by steel. Its main disadvantages are: the appearance is irregular, which makes the product unable to maintain its consistency; the production process is slow and the production efficiency is not high; the noise is loud when used.
Easy to cause secondary damage when damage occurs

Embodiment 2

[0042] A marine seamless motor casing, which is composed of the following components in parts by weight: 70 parts of pig iron, 6 parts of recycled steel, 4 parts of silicon carbide, 2.5 parts of graphene, 1.5 parts of calcined kaolin, 2.5 parts of rare earth mixture, zirconia 1.5 parts, 1.5 parts of amorphous quartz particles, 0.5 parts of antimony, 1.5 parts of potassium tungstate, 1.5 parts of pyrite slag;

[0043] Its preparation process steps are as follows:

[0044] 1) Smelting

[0045] Weigh the above-mentioned raw materials according to the composition formula, and send them into the melting furnace to be smelted into a casting solution, and then flow into the casting system for use;

[0046] 2) vibrating sand

[0047] Vibrating sand machine is used to vibrate the casting mold after the last batch of molding. During the vibration process, the molded shell is separated from the sand mold, and the shell is conveyed out through the output device. The sand mold is broken ...

Abstract

A marine seamless motor casing relates to the field of marine electrical technology and is composed of the following components in parts by weight: 70-80 parts of pig iron, 4-6 parts of recycled steel, 4-6 parts of silicon carbide, and 1.5-2.5 parts of graphene 1.5-2.5 parts of calcined kaolin, 1.5-2.5 parts of rare earth mixture, 1.5-2.5 parts of zirconia, 0.5-1.5 parts of amorphous quartz particles, 0.5-1.5 parts of antimony, 0.5-1.5 parts of potassium tungstate, pyrite 1.5-2.5 parts of slag; the present invention makes a large adjustment to the formula of the traditional motor casing, adding materials such as graphene and rare earth, which changes the performance of the casing, so that the strength and hardness of the casing are very high. When destroyed, no secondary damage can be produced.

Description

technical field [0001] The invention relates to the field of marine electrical technology, in particular to a marine seamless motor casing. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery; thus, the application range of the motor is very wide; and the quantity that needs to be manufactured every year is also extremely large. The motor will generate a certain amount of heat during the working process. In order to improve the heat dissipation efficiency of the motor to ensure the normal operation of the motor; for example, there are multiple heat dissipation strips on the outer surface of the Y series three-phase motor housing; but the housing mainly relies on Mold foundry pouring molding blank. [0003] At present, most of the marine motor shell mark...
