湖南省电力工业局机电安装工程公司第一队在株州电厂安装了两台国产AK-12型汽机,在党的正确领导下,顺利地完成了安装任务,并于1959年7月全部移交生产。经过长期运行考验,安装质量良好,机组振动均在0.01毫米以内。现将安装和试运行过程中在各主要部件上所遇到的一些问题及其解决办法,分别介绍如下,供各兄弟单位参考。一、对轮 1.三号机对轮防窜装置三号机组在第一次起动时,发现发电机转于向汽机侧窜动,使发电机转子电环和静子上固定碳刷螺丝相碰,并引起磨擦而冒火花。停机检查发现两轴头之间有179毫米的距离,如图1所示。停机后,我们在
The first team of the Electrical and Mechanical Installation Engineering Company of Hunan Provincial Electric Power Industry Bureau installed two domestic AK-12 steam turbines in Zhuzhou Power Plant. Under the correct leadership of the Party, the first installation was successfully completed and was completely handed over to production in July 1959 . After long-term operation test, the installation quality is good, the unit vibration is less than 0.01mm. Now the installation and commissioning process encountered in the main components of some of the problems encountered and their solutions, respectively, are introduced below, for the brothers units for reference. First, the round 1. On the 3rd machine on the runway anti-channeling unit No. 3 unit at the first start, found that the generator turn to the turbine side of the play, so that the generator rotor ring and static stator carbon brush screws touch , And cause friction and sparks. The shutdown check found a distance of 179 mm between the two shaft heads, as shown in Figure 1. After the shutdown, we are here
