Analysis on the Cause of Deformation of Marine Explosion-proof Motor
 In the process of Marine Explosion-proof Motor, the failure caused by the base is mainly manifested in its deformation, the seat deformation will directly affect the operation of Marine Explosion-proof Motor. So, what causes the frame to be deformed? Xiaobian specially invited Shi Long motor technology chief engineer to explain:
The deformation caused by the frame is composed of two factors: design and manufacture:
1, the design reasons: not fully in accordance with the theory of structural mechanics design force, such as the base axle, radial tendons size, shape, location design; chassis overall design is not symmetrical. For example, the effective part of the lower part after machining is too small.
2, the production of reasons: timeliness is not in place; metal processing fashion card parts and uneven force, processing finished, release the clamping parts, the seat due to rebound and deformation. Handling deformation, but this is the secondary reason.
Due to the presence of resonance phenomena in the operation of Marine Explosion-proof Motors, it often appears at a certain speed and is fleeting during the start-up process. So the seat deformation is not easy to detect. Due to aging is not in place and the resulting deformation, is not easy to be aware of. Due to the complete release of welding stress takes a long time, so the processing is difficult to find, especially when the duration is short. This is also a typical risk. So in the Marine Explosion-proof Motor production process must pay special attention.
 Case is a Marine Explosion-proof Motor accessories, Marine Explosion-proof Motor is the body weight is relatively heavy, the customer in the installation process, the chassis is damaged, we have to change a motor case. The chassis is different from other assembly parts, especially Marine Explosion-proof Motors.
The material of the motor case is generally cast iron, cast aluminum alloy. Steel (steel), steel and so on. Ordinary motor and Marine Explosion-proof Motor chassis are made of cast iron castings, and then to do the finishing lathe, and stator core with. Because the Marine Explosion-proof Motor special use of the environment, the electrical sealing treatment is better, that is, the internal wiring parts of the motor burned, it will not ignite the external environment of the flammable gas, the general motor case is not explosion-proof isolation function, There is no special sealing action for the motor lead wire.
In order to meet the above requirements, the Marine Explosion-proof Motor chassis can generally use the ordinary chassis, but the underground with YBK2 series of Marine Explosion-proof Motor on the chassis requirements are higher, the general use of Marine Explosion-proof Motor must be used The enclosure is made of steel, and the base, windshield, junction box, insulation structure to take measures to meet the underground operating environment requirements.
