                                                    機床電器原理圖分析
                                                    作者:    發布于:2013-10-31 11:41:09    文字:【】【】【
                                                        在前面安陽機床介紹了機床電氣故障產生的原因,通過原因,確定產生故障的可能范圍,機床電氣設備發生故障后,為了能根據情況迅速找到故障的位置并予以排除,就必須熟悉機床的電路。機床的電路是根據機床的用途和工藝要求而定的,因此了解機床的基本工作原理、加工范圍和操作程序對掌握機床電氣控制電路和各環節的作用具有一定的意義。

                                                        任何一臺機床的電氣電路總是由主電路和控制電路兩大部分組成,而控制電路又可分為若干個控制環節,分析電路時,通常首先從主電路人手,了解機床各運動部件和輔助機構采用了幾臺電動機拖動,從每臺電動機主電路中使用接觸器的主觸頭連接方式,大致可以看出電動機是否有正反轉控制;是否采用了減壓起動,是否有制動等,然后再去分析控制電路的控制形式,結合故障現象和電路工作原理進行分析,便可迅速判斷出故障發生的可能范圍和部位。安陽機床廠家所介紹的這些內容知識,對于我們在實際應用過程中非常有幫助,相關從業人員非常有必要了解這些內容。
