为了适应煤炭工业现代化建设的需要,我厂自1980年以来,组织了一批技术力量研制新产品,使产品由原来的十几种规格发展为现在的六十多种。KBYD系列矿用隔爆型双速三相异步电动机就是近年来研制的新品种之一,其中KBYD 550—132/65—4/8、KBYD450—40/22—4/8两种规格的电机分别于33年8月和85年4月试制成功,将进行工业性试验。该系列双速电机是解决井下工作面输送机起动困难和液力联轴节喷火的有效途径。一、问题的提出无论是采煤,还是掘进、回采、运输、巷道通风都应把保证煤矿井下的安全放在首位,生产井下用防爆电机的厂家在设计和产
In order to meet the needs of the modernization of the coal industry, I plant since 1980, organized a group of technical forces to develop new products, the product from the original specifications for the development of more than 60 now. KBYD series mine explosion-proof two-speed three-phase asynchronous motor is developed in recent years, one of the new varieties, including KBYD 550-132 / 65-4 / 8, KBYD450-40 / 22-4 / 8 two specifications of the motor respectively In August 33 and August 1985 trial successful, will be an industrial test. The series of two-speed motor is to solve the underground face conveyor start-up difficulties and fluid coupling spit fire an effective way. First, the issue raised Whether coal mining, or driving, mining, transportation, tunnel ventilation should ensure the safety of coal mine safety first place, the production of underground explosion-proof motor manufacturers in the design and production
