江西矿山机械厂设计试制的JT-0.8矿用提升绞车新产品样机于一九八三年十二月通过了鉴定。确认该种新产品达到了国内同类产品的先进水平,可以投入批量生产。 0.8米矿用提升绞车是一种量大面广的提升运输设备,是地方小煤矿的主要机电设备。长期以来存在着“能防爆的不调速,能调速的不防爆”的问题,严重影响地方煤矿井下的生产与安全,经常造成矿车掉道及其它机电运行事故。新产品为简化防爆设施仍采用鼠笼型电机,利用行
The prototype of JT-0.8 mining winch designed and tested by Jiangxi Mining Machinery Factory passed the appraisal in December 1983. Confirmed that this new product has reached the advanced level of similar domestic products, can be put into mass production. 0.8 m mine hoist is a large amount of lifting transport equipment, is a small local mine the main electrical and mechanical equipment. For a long time, there is the problem of “no explosion-proof speed control and no explosion-proof speed control”, seriously affecting the production and safety in local coal mines and often causing the drop off of mining cars and other electromechanical operation accidents. New products are still used to simplify the explosion-proof squirrel-cage motor, the use of line
