在瓦斯91看片神器下载正常运作过程中，91看片APP下载经常会遇到震动的情况，瓦斯91看片神器下载根据多年经验总结出这其实是由电机引起的，主要原因归结为以下三种，零部件松动、机械故障和电磁故障。

　　During the normal operation of gas generator sets, we often encounter vibration situations. Based on years of experience, gas generator sets have concluded that this is actually caused by the motor, and the main reasons can be attributed to the following three types: loose components, mechanical failures, and electromagnetic failures.

　　一、转动部分不平衡主要是转子、耦合器、联轴器、传动轮(制动轮)不平衡引起的。处理方法是先找好转子平衡。如果有大型传动轮、制动 轮、耦合器、联轴器，应与转子分开单独找好平衡。再有就是转动部分机械松动造成的。如：铁心支架松动，斜键、销钉失效松动，转子绑扎不紧都会造成转动部分不平衡。

　　1、 The imbalance of the rotating parts is mainly caused by the imbalance of the rotor, coupler, coupling, and transmission wheel (brake wheel). The solution is to first find the rotor balance. If there are large transmission wheels, brake wheels, couplings, or couplings, they should be balanced separately from the rotor. Another issue is the mechanical looseness of the rotating parts. For example, loosening of the iron core bracket, failure and loosening of the diagonal keys and pins, and loose binding of the rotor can all cause imbalance in the rotating parts.

　　二、机械部分故障主要有以下几点：

　　2、 The main mechanical failures are as follows:

　　1、联动部分轴系不对中，中心线不重合，定心不正确。这种故障产生的原因主要是安装过程中，对中不良、安装不当造成的。还有一种情况，就是有的联动部分中心线在冷态时是重合一致的，但运行一段时间后由于转子支点，基础等变形，中心线又被破坏，因而产生振动。

　　1. The axis system of the linkage part is not centered, the centerline is not aligned, and the centering is incorrect. The main cause of this malfunction is due to poor alignment and improper installation during the installation process. There is also a situation where the center lines of some linkage parts coincide in the cold state, but after running for a period of time, the center lines are damaged due to deformation of the rotor support points, foundations, etc., resulting in vibration.

　　2、与电机相联的齿轮、联轴器有毛病。这种故障主要表现为齿轮咬合不良，轮齿磨损严重，对轮润滑不良，联轴器歪斜、错位，齿式联轴器齿形、齿距不对、间隙过大或磨损严重，都会造成一定的振动。

　　2. The gears and couplings connected to the motor are faulty. This type of malfunction is mainly manifested as poor gear meshing, severe tooth wear, poor wheel lubrication, skewed or misaligned couplings, incorrect tooth profile and pitch, excessive clearance or severe wear of gear couplings, all of which can cause certain vibrations.

　　3、电机本身结构的缺陷和安装的问题。这种故障主要表现为轴颈椭圆，转轴弯曲，轴与轴瓦间间隙过大或过小，轴承座、基础板、地基的某部分乃至整个电机安装基础的刚度不够，电机与基础板之间固定不牢，底脚螺栓松动，轴承座与基础板之间松动等。而轴与轴瓦间间隙过大或过小不仅可以造成振动还 可使轴瓦的润滑和温度产生异常。

　　3. Defects in the structure of the motor itself and installation issues. This type of fault is mainly manifested as elliptical shaft neck, bent shaft, excessive or insufficient clearance between shaft and bearing shell, insufficient stiffness of bearing seat, foundation plate, some parts of the foundation, and even the entire motor installation foundation, weak fixation between motor and foundation plate, loose foot bolts, and loose connection between bearing seat and foundation plate. Excessive or insufficient clearance between the shaft and the bearing shell can not only cause vibration, but also lead to abnormal lubrication and temperature of the bearing shell.

　　4、电机拖动的负载传导振动。例如：汽轮发电机的汽轮机振动，电机拖动的风机、水泵振动，引起电机振动。

　　4. The load driven by the motor conducts vibration. For example, the vibration of the steam turbine in a steam turbine generator, as well as the vibration of the fan and water pump driven by the motor, can cause the motor to vibrate.

　　三、电气部分的故障是由电磁方面的原因造成的主要包括：交流电机定子接线错误、绕线型异步电动机转子绕组短路，同步电机励绕组匝间短路，同步电机励磁线圈联接错误，笼型异步电动机转子断条，转子铁心变形造成定、转子气隙不均，导致气隙磁通不平衡从而造成振动。导致电机振动的原因多种多 样，以上仅是笔者在工作中，实际遇到的一些故障总结如上。

　　3、 The faults in the electrical part are mainly caused by electromagnetic factors, including: incorrect wiring of the stator of the AC motor, short circuit of the rotor winding of the wound asynchronous motor, short circuit between turns of the excitation winding of the synchronous motor, incorrect connection of the excitation coil of the synchronous motor, broken bars in the rotor of the cage asynchronous motor, deformation of the rotor iron core causing uneven air gap between the stator and rotor, resulting in unbalanced magnetic flux in the air gap and causing vibration. There are various reasons that can cause motor vibration, and the above is just a summary of some faults encountered by the author in their work.

　　瓦斯91看片神器下载提示您当瓦斯91看片神器下载出现剧烈的不正常震动时，就要考虑是不是以上这些因素导致的，在检查过程中首先要从这三个方面下手进行针对性的检查，来尽快找出原因所在，恢复正常工作。

　　The gas generator set reminds you that when there is severe abnormal vibration in the gas generator set, you should consider whether it is caused by the above factors. During the inspection process, targeted inspections should be carried out from these three aspects to quickly identify the cause and restore normal operation.
