The difference between positive pressure motor and ordinary motor
Information on industrial product production license management
In June 2017, the State Council decided to further adjust the product catalogue for the implementation of industrial product production license management, cancel the production license management of 19 industrial products, and transfer the three types of industrial products from the implementation of production license management to the implementation of mandatory product certification management. The management authority for the production licenses of eight types of industrial products shall be delegated to the quality and technical supervision department of the provincial people's government by the General Administration of Quality Supervision, Inspection and Quarantine. After the adjustment, there are 38 categories of products that continue to implement industrial product production license management, including 19 categories implemented by the General Administration of Quality Supervision, Inspection and Quarantine, and 19 categories implemented by the provincial people's government quality and technical supervision departments.
Today, Ms. participates in the topic of small J to communicate with you about the positive pressure type explosion-proof motor is different from the performance requirements and test judgment of ordinary motors. According to the specific working conditions of the motor, to obtain the production license, in addition to the requirements that the ordinary motor must meet, it is necessary to meet the performance requirements and inspection specifications related to the positive pressure type explosion-proof motor and obtain the explosion-proof certificate.
Positive pressure type explosion-proof motor
The positive pressure type motor is supplemented with clean air or inert gas in the motor and maintains a certain pressure, so that the external explosive mixture can not enter the motor and contact with sparks and heat generating parts generated in the motor, thereby achieving the purpose of explosion proof. According to the gas supply situation, it can be divided into explosion-proof ventilation type and explosion-proof inflation type.
