延安螺桿壓縮機價格
螺桿壓縮機,也稱螺旋式壓縮機,包括螺桿空氣壓縮機和螺桿工藝壓縮機(氯乙烯壓縮機等),螺桿機為容積式雙螺桿噴油壓縮機,一般為箱式撬裝結構。
螺(luo)桿(gan)壓(ya)(ya)縮(suo)機分為單(dan)螺(luo)桿(gan)壓(ya)(ya)縮(suo)機和雙螺(luo)桿(gan)壓(ya)(ya)縮(suo)機,直到(dao)1934年瑞(rui)典(dian)皇家(jia)理(li)工學(xue)院A.Lysholm才奠定了螺(luo)桿(gan)式壓(ya)(ya)縮(suo)機SRM技(ji)術,并開始在工業上應(ying)用,取得(de)了迅速的發展。
