Diesel generator set heat sink maintenance method

Diesel generator set heat sink maintenance method:
First, the coolant of the generator set heat sink is usually very hot, and it is pressure. It is not possible to consolidate the heat sink or remove the tube when not cooled. Do not work or open the fan protection when the fan is rotated. cover.

Second, corrosion problems are mainly caused by the heat sink. To keep the pipe joints do not leak, and periodically add water from the top of the radiator to keep the system \"no gas\". The radiator should not be in part of the injection of water, as this will accelerate corrosion. For unmimerated generators, all the water is taken or full. If possible, with distilled water or natural soft water and add an appropriate amount of rust.

Third, external cleaning: in a large or contulsive environment, the gap of the heat sink may be blocked by debris, insect, etc., thereby affecting the efficiency of the heat sink. Cleaning of these light deposits can be sprayed with low pressure hot water, and the vapor or water is ejected from the front of the radiator. If ejection from the reverse direction will only blow the dirt into the center. When using this method, it is necessary to use a cloth barrier diesel engine and an alternator. The stubborn deposits cannot be removed in the above method, and the heat sink can be removed in the hot alkali water for about 20 minutes, and then rinse with hot water.

Fourth, internal cleaning: If the joint is leaking, there is no choice for a long time to use a hard water irrigation, or because the power generation runs for a period of time and useless rust, the system may block the scale. Clearing scale can be made as follows:
1. Drain the water from the heat dissipation system, then remove the pipe from the diesel engine;
2, accurate 4% of the excessive solution and clean water, pour the acid solution into the water, do not turn over;
3, wait a few minutes to mix, then heat the solution to 49 ° C (120 ° F), which is the height of Zui, which is not high;
4, slowly put the solution through the filter cap or a division into the pipe, which will boil the foam. When the chemical reaction is stopped, the heat of the heat is filled with heat;
5. Let the solution stay in the system minutes, then put the solution from the bottom pipe or drain outlet back to the original container;
6. Check the inside of the water tank, such as still dim, then repeat the above steps, add the acid solution to 8%;
7. After descaling, press the reaction in the following steps: Take the container to be filled with water, heating to the boiling point, plus the daily soda crystal, as follows: 500g Soda 20 lissive water (1 lb With 4 Golden Water), use this solution to incorporate the radiator and let it flow back to the original container;
8. Rushing the heat exchanger several times with the above method. After the zui is filled, it will stop in the radiator for at least one hour, and rinse with hot water after emptying;
9. Before using the radiator to reinstall, use water to test or leakage, sometimes due to removal of scale;
10. Prior to Running, the coolant should be added to the necessary corrosion and the appropriate amount of condensing agent.
