發電機組作為小功率機組，現如今也應用廣泛，但是你知道發電機組振動故障及節能措施有哪些么?今天焦化發電機組小編一一給大家講解一下，走過路過不能錯過，這可都是知識點!

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!

眾所周知，電機的布局一起包含電氣和機械，也能夠說是機械和電氣的結合點。所以說，它的毛病要一分為二的剖析。通常來講，電機振蕩是因為轉變有些不平衡、電磁方面或機械毛病的緣由招致的。

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、轉變有些不平衡首要是轉子、耦合器、聯軸器、傳動輪(制動輪)不平衡招致的。處置辦法是先找好轉子平衡。如果有大型傳動輪、制動輪、耦合器、聯軸器，應與轉子分隔獨自找好平衡。再有就是轉變有些機械松動形成的。如:鐵心支架松動，斜鍵、銷釘失效松動，轉子綁扎不緊都會形成轉變有些不平衡。

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、機械有些毛病有以下幾點:

2、 Some mechanical problems are as follows:

1、聯動有些軸系不對中，定心不正確。這種毛病發生的緣由首要是裝置過程中，對中不良、裝置不妥形成的。還有一種狀況，就是有的聯動在冷態時是重合共同的，但運轉一段時間后因為轉子支點，根底等變形，因此發生振蕩。

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、與電機相聯的齒輪、聯軸器有毛病。這種毛病首要表現為齒輪咬合不良，輪齒磨損嚴峻，對輪光滑不良，聯軸器傾斜、錯位，齒式聯軸器齒形、齒距不對、空隙過大或磨損嚴峻，都會形成必定的振蕩。

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、電機自身布局的缺點和裝置的難題。這種毛病首要表現為軸頸橢圓，轉軸曲折，軸與軸瓦間空隙過大或過小,軸承座、根底板、地基的某有些甚至整個電機裝置根底的剛度不行，電機與根底板之間固定不牢，底腳螺栓松動，軸承座與根底板之間松動等。而軸與軸瓦間空隙過大或過小不只能夠形成振蕩還可使軸瓦的光滑和溫度發生反常。

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、電機拖動的負載傳導振蕩。例如:汽輪發電機的汽輪機振蕩，電機拖動的風機、水泵振蕩，招致電機振蕩。

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.
