How can I quickly eliminate a diesel engine after it fails? Hainan buys diesel generators to buy diesel generators. Sanya buys diesel generators. First, we must have a more detailed understanding of the working principle of diesel engines. Secondly, Wenchang buys diesel generators Qionghai to buy diesel generators. Wanning buys diesel generators to understand in detail. The structure and working principle of each system and the relationship between the various systems, Changjiang purchase diesel generator Ledong to buy diesel generator Qiongshan to buy diesel generators can quickly determine the fault location according to the performance of the fault. Although the performance of the fault is ever-changing, there is always a certain regularity to follow. In summary, Chengmai purchases a diesel generator. Lin Gao purchases a diesel generator. The dragon roll buys a diesel generator. There are only the following points:
1. Abnormal sound: abnormal knocking sound, purchase of diesel generator in Zhangzhou, Baoting diesel generator, cannon sound, blowing sound;
2. Abnormal operation: Hainan sells diesel generators. Haikou sells diesel generators. Dingan sells diesel generators. Diesel engines are not easy to start, and they produce severe vibrations during operation, with no moving load;
3, the appearance is abnormal: white smoke, black smoke, blue smoke, air leakage, oil leakage, water leakage;
4, temperature anomaly: Wanning diesel generator Haikou manufacturers diesel generator Wuzhishan diesel generator locomotive cooling water temperature is too high, the bearing is overheated;
5. Abnormal pressure: Lingshui sells diesel generators. Lingshui purchases diesel generators. Baisha purchases diesel generators. The oil pressure is too low and the pressure inside the cylinder is too low;
6, the smell is abnormal: smoke, burnt, odor.
After the diesel engine fails, it is necessary to diagnose the fault. Baisha sells diesel generators. Hainan generators Haikou generators Commonly used methods are:
1. Abnormal sound judgment: Determine the location of abnormal sound and different sounds, Sanya generator Qionghai generator Dongfang generator If the main bearing gap is too large, the sound will be very dull, and the valve knocking piston will be crisp.
2, the site stop method: After analysis, Linwang generator Tunchang generator Lingshui purchase diesel generator suspected that the fault caused by that part can stop the part, observe whether the symptoms disappear, generally used to determine whether the cylinder is faulty Wait.
3. Comparison method: Suspected that the fault is caused by a certain component or part, Haikou Cummins diesel generator Hainan Shangchai diesel generator Sanya Cummins diesel generator can update the parts and compare the working conditions.
4. Heuristic method: Exploratory adjustment of the diesel engine based on preliminary analysis and judgment. Qionghai Diesel Motors Diesel Generators Wanning Cummins Diesel Generators Changjiang Shangchai Diesel Generators For example, diesel engines emit smoke. If judged, the injection pressure can be changed tentatively or the advance angle can be changed within a small range to observe the change effect.
5, instrument, instrument inspection: the use of instruments, instruments to check the diesel engine, such as the use of cylinder pressure gauge to check whether the pressure meets the requirements to determine whether there is a fault such as air leakage.
In actual work, the above various means can be comprehensively used for fault diagnosis. Hainan imports diesel generators from Haikou to find faults quickly and accurately.
In short, the mastery of the regularity of diesel engine faults will be of great help to the actual repair work. At the same time, it is good at summing up and making records for future search.
Rubber Anti-oxidant Agent is a kind of rubber to join in the process of production can delay the ageing of the rubber, prolonging the service life of the rubber chemicals.
Ningbo Actmix produce the non-staining anti-oxidant for vulcanizates based on natural and synthetic rubbers, included Actmix®MMBI-70, Actmix®MBI-80, Actmix®ZMMBI-50, Actmix®ZMMBI-70, Actmix®NDBC-75 etc, application for variety of transparent,white and colorful rubber products, fabric coating, especially for heat-resistant rubber parts.
