采用先进技术改进老旧设备是节约能源提高工效的一个重要途径.蒸汽锤是有了蒸汽机以后的产物,工业上制造和使用蒸汽锤已有一百多年的历史了.蒸汽锤的优点是结构比较简单,维修方便,使用寿命长.但最大的缺点是热工效低,能耗高.80年代前后,工业发达国家已开始使用电液锤.电液锤是以电动机带动液压泵产生液压作为动力把气动液压这一先进技术用于锻造设备的.电液锤的最大优点是省去动力锅炉系统,节约建设投资;电液锤比蒸汽锤可节约能源90%以上,经济效益明显.特别是近年来,我国除研制成功并使用一批电液锤取代蒸汽锤外,不少工厂还自力更生以“改头”的
The use of advanced technology to improve the old equipment is an important way to save energy and improve work efficiency.Steam hammer is a product of the steam engine after the industrial manufacture and use of steam hammer has a history of more than one hundred years.The advantage of steam hammer is the structure Relatively simple, easy maintenance, long service life, but the biggest drawback is the thermal efficiency, high energy consumption around the 1980s, the industrialized countries have begun to use electro-hydraulic hammer. Electro-hydraulic hammer hydraulic pump driven by a hydraulic motor as the driving force The most important advantage of electro-hydraulic hammer is to save the power boiler system, saving construction investment; Electro-hydraulic hammer than steam hammers can save energy more than 90%, economic benefits are obvious, especially in recent years In addition, our country has successfully developed and used a number of electro-hydraulic hammers instead of steam hammers, and many factories have also relied on their own efforts to “re-head”
