蒸汽锤的能源利用率极低,大都不到1％,空气锤的能源利用率一般不到3％;改为电液锤能源利用率,可以提高到20％。由于液流的阻力和速度的平方接近成正比,因此,可把现有适用于低速机械的液压技术,用到锻锤上去,使它适应锻锤那样高速、高频次、多变、高可靠性的要求,但在工作条件十分恶劣的情况下,是很难达到的。目前电液锤存在的问题是:动作灵活性差、打击频次低,不能急停收锤等缺点,除此之外,价格昂贵。但是,将蒸空锤改为电液锤,经过生产运行证明动作灵活,性能好,并能急停收锤,能达到工艺要求。蒸空锤改电液锤的办法是:取掉原有汽缸,换上电液驱动头,原有机架和基础不动,锤的操作方式和 Steam hammer energy efficiency is very low, mostly less than 1%, air hammer energy efficiency is generally less than 3%; to hydraulic hammer energy efficiency, can be increased to 20%. As the flow resistance and the square of the speed close to proportional to the existing low-speed machinery can be applied to the hydraulic technology used to hammer up to make it as forging hammer that high-speed, high frequency, changeable, highly reliable Sexual requirements, but it is very difficult to achieve in the very bad working conditions. The current problems of electro-hydraulic hammer is: poor mobility, low attack frequency, can not stop receiving hammer and other shortcomings, in addition, the price is expensive. However, the steam hammer changed to electro-hydraulic hammer, after production and operation proved flexible, good performance, and emergency stop hammer, can meet the process requirements. Steam hammer to change the method of electro-hydraulic hammer is: remove the original cylinder, put electro-hydraulic drive head, the original rack and the foundation does not move, the hammer mode of operation and
