气体渗碳出炉时多用手压泵将炉盖升起。这样操作劳动强度大,而且延缓出炉时间,增加工件脱碳机会。为此我们用齿轮泵代替手压泵。经使用表明,齿轮泵明显减轻
Gas carburizing baked more hand pressure pump lid will rise. Such labor-intensive operation, but also delay the baked time, increase the chances of decarburization of the workpiece. For this purpose we use a gear pump instead of a hand pump. After use shows that gear pump significantly reduced
