Operations to be avoided during maintenance of MTU generators

The use of the generator to achieve better results, but also to prevent the phenomenon of influence on use, to carefully identify some problems of the generator, timely processing, so as to avoid the impact of use, if the generator fault is found, there are many maintenance ways can be used, also to avoid misoperation, Next, we will introduce the common misoperation of generator maintenance in Dongguan.

1. Failure to correctly judge and analyze faults during equipment maintenance

During maintenance, some maintenance personnel are not clear about the mechanical structure and principle of the equipment, do not carefully analyze the cause of the fault, and can not accurately judge the fault location. They dismantle and unload equipment blindly based on approximate and similar ideas. As a result, not only was the original fault not eliminated, but new problems arose due to poor maintenance skills and techniques.

2. The phenomenon of blindly replacing parts and repairing parts exists to varying degrees.

It is relatively difficult to judge and eliminate equipment failure. Some maintenance personnel always use the method of replacement test, whether large parts or small parts, as long as they think that parts may cause failure, they will be replaced one by one. As a result, not only did they fail to troubleshoot, but they also arbitrarily replaced parts that should not have been replaced, increasing maintenance costs. Some faulty parts can be repaired to fully recover their technical performance without a complicated repair process. During maintenance, the cause and location of the fault should be carefully analyzed according to the fault phenomenon, and the technical performance of the repairable parts should be restored by means of repair to prevent blind replacement of parts.

3. There are many phenomena that do not pay attention to detecting the fit clearance of parts. In the maintenance of common diesel generators, there are strict requirements on the matching clearance between piston and cylinder liner, piston ring clearance, piston top clearance, valve clearance and so on. Maintenance needs to be measured, do not meet the clearance requirements of the parts should be adjusted or replaced.

4. When assembling the equipment, the parts are installed upside down.

When maintaining equipment, some parts have strict direction requirements; A part will work only if it is installed correctly. Some parts external features are not obvious, can be installed in reverse direction. In practice, they are often installed in reverse, leading to early damage of parts, abnormal operation of machinery, equipment damage accidents, etc.

Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
