Study on cooling of water-cooled motor of EML340 continuous miner
LI Ting-jie
Abstract：Aiming at the performance characteristics and operating conditions of EML340 continuous miner, the author introduces the causes for overheating of explosion - proof motor in EML340 continuous miner, and analyzes the characteristics of various cooling modes of the motor. Deduces the calculation formula of the heat and the temperature rise of the motor, and calculates the calculation formula of the water cooling system. The calculation formula of the total cooling water flow rate, the actual temperature rise and the cooling water flow rate is given. The explosion-proof water-cooled motor for cutting mechanism of EML340 continuous shearer is calculated and verified, finally, the advantages of explosion-proof water cooling motor for continuous shearer are concluded.
