为了提升压铸工艺中的设备效能,着重关注了变频调速技术在压铸过程中的优化作用。传统的压铸机采用的异步电动机通常在恒定速度下运作,造成能源浪费。变频调速技术作为一种创新解决方案,能够有效降低能耗并提升整体工作效率。以某企业800 t压铸系统为例,详细阐述了实施变频转换的实际操作流程,以及实施过程中涉及的关键步骤。为对比改造前后性能的变化,对改装后的压铸设备进行了效能特性的专门测试。实验数据表明,变频改造带来了显著的节能效果,同时电动机的运行表现也得到了极大提升。这一成功案例不仅证实了技术改造的安全可行性,还提供了经济效益参考,为同类液态压铸机的变频调速改造提供了参考。

In order to improve the equipment efficiency in the die-casting process,the optimization role of variable frequency speed regulation technology in the die-casting process is emphasized.The asynchronous motor used in traditional die-casting machines usually operates at a constant speed,resulting in energy waste.As an innovative solution,variable frequency speed regulation technology can effectively reduce energy consumption and improve overall work efficiency.Taking the 800 t die-casting system of a certain enterprise as an example,the actual operation process of implementing frequency conversion and the key steps involved in the implementation process are elaborated in detail.To compare the performance changes before and after the renovation,specialized tests are conducted on the efficiency characteristics of the modified die-casting equipment.Experimental data shows that the frequency conversion transformation has brought significant energy-saving effects,and at the same time,the operating performance of the motor has also been greatly improved.This successful case not only confirms the safety and feasibility of the technological transformation,but also provides economic benefits reference,and provides a practical reference template for the frequency conversion speed regulation transformation of similar liquid die-casting machines.
