Description&Application

Wolong supplys the YBK3 series explosion-proof three-phase asynchronous motor for underground coal mine is axially ventilated, fully enclosed, fan-cooled, squirrel-cage explosion-proof three-phase asynchronous motor, which is the basic series of explosion-proof motors designed to replace the YBK2 series in China motor industry, with the advantages of high efficiency, high torque, strong overload capacity, low noise, low vibration, large temperature rise margin, good performance, easy installation and maintenance, and long service life.

It is mainly used in coal mine, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other sectors.

Implementation standards

The explosion-proof performance of YBK3 series explosion-proof three-phase asynchronous motors conforms to the national standards GB3836.1-2010 Explosive Environment Part 1: General Requirements for Equipment and GB3836.2-2010 Explosive Environment Part 2: General Requirements for Equipment.

GB3836.2-2010 "Explosive Environment Part 2: Equipment Protected by Flame-proof Shell "d"" and industry standard MT/T451-2011 "General Technical Specification for Safety Performance of Flame-proof Low-voltage Three-phase Asynchronous Motors for Coal Mines" and JB/T9593.1-2015 "YBK3 Series Flame-proof Three-phase Asynchronous Motors for Underground Coal Mines". YBK3 Series Flame-proof Three-phase Asynchronous Motors for Underground Use in Coal Mines (Block No. 80-355)", it is made into flame-proof type, and the explosion-proof mark is "Exd IMb". It is suitable for use in underground coal mines where there is a danger of methane mixture and coal dust explosion.

YBC motor can be customized according to customer requirements to Nanyang brand, Wolong brand, Schorch brand, Brook etc in Wolong electric group.
