How to Clear Carbon Deposit of 560KW Weichai Generator Set

The carbon deposition in 560KW Wechai generator set is actually the product of incomplete combustion of diesel and engine oil flowing into the combustion chamber. It is a common phenomenon that carbon deposition occurs on the top of diesel piston, on the wall of combustion chamber and around the valve. A large amount of carbon deposit will affect the performance of diesel generator set to a certain extent, and its final performance is poor combustion, heat transfer deterioration, and reduce the reliability of fuel injector.

There are many reasons for carbon deposition in power generation units. Here Dingbo Power summarizes six main reasons for carbon deposition.

1. Abnormal operation of fuel injector, such as poor atomization, oil dripping, too high or too low injection pressure, too early or too late injection time and too much injection quantity, will cause incomplete combustion of some fuels.

2. Serious oil channeling.

3. Serious air leakage.

4. The temperature of cooling water is too low, which affects the normal combustion of fuel.

5. The brand of diesel and engine oil is not right, the quality is poor, and carbon slag is formed after combustion.

6. The diesel engine is overloaded or the temperature is too high, and the ignition is too early, which makes the fuel combustion incomplete.

Generally, the composition of carbon deposit is closely related to the structure of diesel engine, the location of components, the types of diesel and engine oil, the operating environment and working time. Carbon deposit is a complex mixture of gum, asphaltene, oil coke, engine oil and carbon, which is caused by insufficient combustion of diesel and engine oil in the combustion process and under the action of high temperature. The carbon deposit will affect the heat dissipation function of some diesel engine parts, lead to the deterioration of heat transfer conditions and the decrease of combustibility, and even lead to overheating of parts and cracks.

Therefore, when there is carbon deposit in 560KW Weichai generator set, we should clean it in time. Here Dingbo Power tell you how to clean the carbon deposit.

At present, the more common removal is the use of mechanical removal, chemical treatment and electrolysis method of three methods for carbon removal, the following Cummins manufacturers for you to answer the specific methods of these three methods.

(1)Mechanical removal method.

First, remove the carbon deposit with wire brush and scraper. In order to increase efficiency, when we use wire brush, the electric drill can drive it to rotate through the flexible shaft. This method is very simple. This method is often used for small maintenance points, but the efficiency is very low. It is easy to damage the surface of the parts, and the carbon deposit is not very good. It can be completely removed. Of course, in addition, the method of spraying nuclear chips can also be used to remove carbon deposits. Because the chip is stronger than the metal, when the impact is strong, the noumenon will deform. So the surface of the part will not be scratched or scratched easily, and the production efficiency is also very high. This method is simply that compressed air is used to blow and impact the surface of parts with carbon deposit, and actively destroy the surface material of carbon deposit, so as to achieve the purpose of basic removal.

(2)Chemical treatment.

For the surface of some finished parts, and not using machinery to remove them, we can use chemical methods. First of all, immerse the parts in sodium hydroxide, sodium carbonate and other solutions, temperature 80 ~ 95 ℃ is more suitable, which can be easy to dissolve or emulsify oil. After the coke becomes soft, take it out about 2 to 3 hours, and then remove the coke with a brush. Then add 0.1 ~ 0.3% potassium dichromate hot water to clean it, and dry it with compressed air.

(3)Electrolytic method.

Using alkali solution as electrolyte, the workpiece is connected to the cathode to remove carbon deposit under the combined action of chemical reaction and hydrogen stripping. This method is more efficient, but we should master the use of norms. For example, the specification of valve electrochemical method is voltage 6V, current density 6A/DM2, electrolyte temperature 135~145℃, electrolysis time 5~10 minutes.
