目前,在我国螺杆泵已在石油、化学、电力、机床、化纤、冶金、造船等工业部门逐渐得到应用。较多的是代替离心泵、齿轮泵或往复泵作输送泵,润滑泵,燃油泵,液压泵用。近年来这种泵在冶金行业中的应用推广较快。尤其在轧钢系统中的应用较多。现就这个问题谈点粗浅的看法。 At present, the screw pump in China has gradually been applied in petroleum, chemical, electric power, machine tools, chemical fiber, metallurgy, shipbuilding and other industrial sectors. Most of them are used instead of centrifugal pumps, gear pumps or reciprocating pumps as conveying pumps, lubrication pumps, fuel pumps, and hydraulic pumps. In recent years, the application of this type of pump in the metallurgical industry has been rapidly promoted. Especially in the rolling system applications. We will now talk about the superficial views on this issue.
