为了提高电厂输煤系统的机械化和自动化水平,改善劳动条件,减轻劳动强度,我院在参照国外同类产品的基础上,研究试制了30050型电动推杆(推力300公斤,行程500毫米)。电动推杆是一种由电动机带动的往复式
In order to improve mechanization and automation level of power plant coal handling system, improve working conditions and reduce labor intensity, our hospital made a trial manufacture of 30050 electric push rod (thrust 300 kg, stroke 500 mm) on the basis of referring to similar foreign products. Electric push rod is a motor-driven reciprocating
