Sadden | Corrosion is the main cause of radiator failure

15kw silent gasoline generator direct price is how much?

The Saden generator Penggong reminds you that when using a generator to perform routine maintenance on the generator, it is necessary to pay attention to whether it is for self repair, replacement of parts, or for other personnel. Such mistakes, in order to ensure that Saden gasoline generators meet maintenance requirements, work properly. Saden Gasoline Generator, I hope you enjoy your machine!
In the whole body of the Sadden gasoline generator set, the radiator tank plays an important role in ensuring the normal operation of the generator set. If it is used improperly, lighter ones can damage the Sardon petrol engine and generator set. When it is more serious, it may cause sa The gasoline engine was scrapped. In the after-sales complaint received by the Saden generating unit, many problems are related to the use of water tanks. Below, Sa Dion power technicians summarized the following points for the use and maintenance of the cooling water tank, for your reference.
The first is that while the Saden generating set is in operation, the coolant in the cooling water tank is usually very hot and there is pressure. Therefore, it is forbidden to arrange the radiator or remove the pipe without cooling, and not to operate the radiator while the fan is rotating. Or open the fan guard.

Saden technicians found that corrosion problems are the main cause of radiator failure. It is recommended that the joints of the pipes be inspected regularly so that they do not leak, and that the tank is regularly filled with water to evacuate the air inside the system. The radiator tank should not be partially filled with water, as this will often accelerate the corrosion process. For non-operating generator sets, empty or fill all the tanks. If conditions permit, it is best to use distilled water or natural soft water, and add an appropriate amount of rust inhibitor.
One problem is the cleanliness of the tank. Tank cleaning is divided into external cleaning and internal cleaning. This is an extremely important part that will directly affect the use of radiators and thus affect the use of the entire generator set.
Let me talk about external cleaning. In generator sets that work in open air, the gaps in the radiator may be blocked by debris, insects, and other debris. Frequent spraying with low-pressure hot water (appropriately added detergent) can be used to inject steam or water from the front of the radiator to the fan. When spraying, use cloth to block the Sadden gasoline engine and alternator. If the deposit is difficult to remove, the radiator can be removed and soaked in hot alkaline water for about 20 minutes, then rinsed with hot water.
For the internal cleaning of the generator, the main purpose is to remove the scale in the tank. Follow these steps:
1. Drain the water from the cooling system, and then disconnect the pipe from the place where the Sardon Gasoline Engine is connected; 2. Prepare a 4% rust removing acid solution and clean water (pay attention to pouring acid into the water, not the other way around) . Let it melt for a few minutes and then heat the solution to 49°C (120°F). 3. Slowly pour the solution through the filter cap or one of the tills into the tubing where foam will form. When the chemical reaction has stopped, fill the radiator with the hot solution; 4. Allow the solution to stay in the system for a few minutes, then return the solution from the bottom pipe or drain to the original container; 5. Check the inside of the tank, if still With scale, repeat the above steps to increase the acid solution to 8%.
After descaling, the neutralization of the acid is performed in the following steps: the vessel is filled with clean water and heated to the boiling point, plus daily soda crystals, in the following proportions: 500g soda with 20 liters of water (1 pound with 4 gallons Water), use this solution to fill the radiator, and then let it flow back to the original container;
Rinse the heatsink several times with the above method, and then fill it in the radiator for at least one hour after filling, then rinse with hot water after emptying.
