随着井下综采设备和支护设备的大型化,以及深井、超深井的不断出现,迫切需要大型防爆提升机。目前,井下防爆提升机防爆型式可分为液压防爆和电气防爆两种。由于电气防爆产品向大功率发展有困难,且价格昂贵,故目前大功率井下防爆提升机常采用液压防爆式。JKYB-3.5×2.5 J单绳缠绕式单筒液压防爆提升机是由洛阳中重自动化工程有限公司于2011年为徐
With the large-scale downhole comprehensive mining equipment and support equipment, as well as the emergence of deep and ultra-deep wells, the urgent need for large explosion-proof hoist. At present, underground explosion-proof explosion-proof hoist explosion-proof type can be divided into two kinds of hydraulic explosion-proof and electrical explosion-proof. As the electrical explosion-proof products to the development of high-power difficulties, and expensive, so the current high-power underground explosion-proof hoist often use hydraulic explosion-proof.
