QJZ-400/1140(660)R
从属类别:矿用隔爆兼本质安全型交流软起动器   
 
 
用途 Application
本起动器主要用于井工煤矿、露天煤矿、滞金、港口、选煤厂、发电厂等生产设备的软起动及软停车。
随着我国煤炭生产机械化、自动化程度的不断提高,长距离、大功率、大运量、高速度的采掘运设备日益增多,软起动已广泛应用于刮板输送机、皮带输送机、绞车、水泵、乳化液泵、主扇、局扇等设备的控制。
This starter is mainly applied to soft start and soft stop for production equipments in coal mine,strip coal mine,metallurgy, harbor coal washery,power house,etc
Along with the mechanical and autimatic improvement in our country,and the increase of the excavation and transport equipment with long-distance,high-power,high-freight volume and high-speed advantages,the soft starter has been widely applied to contrlo equipments such as redler, belt, belt conveyer, winch, water pump,emulsion emulsion pump,major blower,portable blower.
