推進機設備:推進機在整條生產線中起到持續輸送推力的作用,通過調節上下部壓輥機構將鋼管壓緊于整條生產線軸線上,壓輥機構轉動時產生摩擦力將鋼管推動向前運行,運行時可以變頻調速實現與整條生產線速度匹配。 Propelling machine: the propelling machine plays a role of continuous transmission of thrust in the whole production line. The steel pipe is compressed on the axis of the whole production line by adjusting the upper and lower roller pressing mechanisms. When the roller pressing mechanism rotates, th
