.Jining explosion-proof motor
Jining series of explosion-proof three-phase asynchronous motors for underground coal mines are axially ventilated, fully enclosed, self-fan cooling, squirrel cage type explosion-proof three-phase asynchronous motors. They are an update of the new design that replaced the series in my country. The updated basic series of flameproof motors for underground coal mines have the advantages of high efficiency, large torque, strong overload capacity, low noise, small vibration, large temperature rise margin, good performance, convenient installation and maintenance, and long life. It has the advantages of reasonable structure, safe and reliable use, and beautiful appearance. The product technology level has reached the domestic advanced level.
The power level and installation dimensions of this series of motors comply with the International Electrotechnical Commission standards, and their corresponding relationships are the same as those of the Federal German Industrial Standards. The center height is (~) the power range is (.~) and the synchronous speed is,,,,/. The voltage is / or /.
The explosion-proof performance of this series of motors complies with the provisions of "General Requirements for Electrical Equipment for Sexual Gas Environments, Part 2" and "Electrical Equipment for Sexual Gas Environments, Part 2 Explosion-Proof Type". It is made into an explosion-proof type, and the explosion-proof mark is. It is suitable for underground mining working faces in coal mines where there is danger of methane mixture and coal dust.
