发电机组作为小功率机组，现如今也应用广泛，但是你知道发电机组振动故障及节能措施有哪些么?今天焦化发电机组小编一一给大家讲解一下，走过路过不能错过，这可都是知识点!

As a small power unit, the generator set is also widely used now, but do you know what are the vibration faults and energy-saving measures of the generator set? Today, the small editor of coking power generation unit will explain to you one by one. You can't miss it when you pass by. It's all knowledge points!

众所周知，电机的布局一起包含电气和机械，也能够说是机械和电气的结合点。所以说，它的毛病要一分为二的剖析。通常来讲，电机振荡是因为转变有些不平衡、电磁方面或机械毛病的缘由招致的。

As we all know, the layout of the motor includes electrical and mechanical together, which can also be said to be the combination of mechanical and electrical. Therefore, its defects should be analyzed in two parts. Generally speaking, the motor oscillation is caused by some unbalanced, electromagnetic or mechanical problems.

一、转变有些不平衡首要是转子、耦合器、联轴器、传动轮(制动轮)不平衡招致的。处置办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，应与转子分隔独自找好平衡。再有就是转变有些机械松动形成的。如:铁心支架松动，斜键、销钉失效松动，转子绑扎不紧都会形成转变有些不平衡。

1、 The transformation of some unbalance is mainly caused by the unbalance of rotor, coupler, coupling and transmission wheel (brake wheel). The solution is to find the rotor balance first. If there are large transmission wheels, brake wheels, couplings and couplings, they should be separated from the rotor and balanced separately. Another is the transformation of some mechanical looseness. For example, if the iron core support is loose, the oblique key and pin are loose due to failure, and the rotor is not tightly bound, the transformation will be somewhat unbalanced.

二、机械有些毛病有以下几点:

2、 Some mechanical problems are as follows:

1、联动有些轴系不对中，定心不正确。这种毛病发生的缘由首要是装置过程中，对中不良、装置不妥形成的。还有一种状况，就是有的联动在冷态时是重合共同的，但运转一段时间后因为转子支点，根底等变形，因此发生振荡。

1. Some shafting of linkage is not aligned and centering is incorrect. This kind of fault is mainly caused by poor alignment and improper installation during the installation process. Another situation is that some linkages are coincident in cold state, but oscillations occur after a period of operation due to the deformation of rotor fulcrum and root.

2、与电机相联的齿轮、联轴器有毛病。这种毛病首要表现为齿轮咬合不良，轮齿磨损严峻，对轮光滑不良，联轴器倾斜、错位，齿式联轴器齿形、齿距不对、空隙过大或磨损严峻，都会形成必定的振荡。

2. The gear and coupling connected with the motor are defective. This kind of problem is mainly manifested as poor engagement of gears, severe wear of gear teeth, poor smoothness of coupling, inclination and dislocation of coupling, incorrect tooth shape and pitch of toothed coupling, excessive gap or severe wear, which will form certain oscillation.

3、电机自身布局的缺点和装置的难题。这种毛病首要表现为轴颈椭圆，转轴曲折，轴与轴瓦间空隙过大或过小,轴承座、根底板、地基的某有些甚至整个电机装置根底的刚度不行，电机与根底板之间固定不牢，底脚螺栓松动，轴承座与根底板之间松动等。而轴与轴瓦间空隙过大或过小不只能够形成振荡还可使轴瓦的光滑和温度发生反常。

3. The disadvantages of the motor's own layout and the difficulties of the device. This problem is mainly manifested in the following aspects: the journal is elliptical, the rotating shaft is tortuous, the gap between the shaft and the bearing bush is too large or too small, the stiffness of the bearing pedestal, the root plate, some parts of the foundation and even the entire motor device is not good, the fixation between the motor and the root plate is not firm, the anchor bolts are loose, and the bearing pedestal and the root plate are loose. However, too large or too small gap between shaft and bearing bush can not only cause oscillation, but also make the smoothness and temperature of bearing bush abnormal.

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

4. The load carried by the motor oscillates. For example, the vibration of steam turbine of steam turbine generator, the vibration of fan and water pump driven by motor will cause the vibration of motor.
