The Particularity Of Explosion-proof Motors Compared To Ordinary Motors

The particularity of explosion-proof motors compared to ordinary motors

There are many categories of motors, different categories of motor qualification management and production process management, there are some differences to varying degrees, today, we briefly communicate with you about the difference between explosion-proof motors and ordinary motors.

Due to the particularity of the application environment of explosion-proof motors, as well as the safety risks in the application process, the mechanical structure, protection level and parts of this type of motor have relatively strict requirements, and the material of parts, mating length, surface roughness of the mating surface, etc. are relatively special requirements for ordinary motors, and the base, end cover and junction box and other parts of the explosion-proof motor must be used after passing the hydrostatic test; Therefore, the production and manufacturing process of explosion-proof motors is relatively complicated, especially the process testing and testing of parts and components is more troublesome.

Before 2019, explosion-proof motors are managed in accordance with the way of production license management, that is, enterprises to produce and repair explosion-proof motors should obtain corresponding production licenses in accordance with relevant requirements: from 2019, the state comprehensive overall management situation, the explosion-proof motor from production license management to 3C certification management. In order to further ensure the effectiveness of management, the product laboratory adopts a designated method to make it clear, that is, the non-designated laboratory is not qualified to issue a test report for 3C certification.

From the perspective of motor manufacturing and application, no matter what way to manage, put safety in the first place, is the motor manufacturers and applications must adhere to the principle, whether it is the original production license management or the current implementation of 3C certification management, the management process is only for the process inspection and sample test conclusions of the comprehensive evaluation, and how to achieve each motor in line with the relevant technical specifications requirements is actually more important, which is also the motor manufacturer credit and integrity of the specific embodiment.

In the process of random inspections of explosion-proof motors at different levels in recent years, the unqualified ones repeatedly found have sounded the alarm for the quality and safety management of this type of motor, so that every motor leaving the factory meets the requirements, which is the safety commitment that explosion-proof motor manufacturers must keep.
