As we all know, the cooling water tank of the coking generator set should use coolant. But some users think that the tap water is very convenient. Instead of the cooling liquid of the diesel generator, the water tank will be full of scale after a long time. The cooling system of the generator may be blocked by scaling. So how to remove the scale?

　　發電機組的除垢工作可按以下步驟進行:

　　The descaling of the generator unit can be carried out as follows:

　　1.從冷卻系統排水，從柴油發電機連接處拆卸管道;

　　1. Drain water from the cooling system and remove the pipe from the connection of diesel generator;

　　2.準備4%除銹酸溶液和清水。將酸性溶液按比例倒入干凈的水中。

　　2. Prepare 4% derusting acid solution and clear water. Pour the acid solution into clean water in proportion.

　　3.讓混合物混合幾分鐘，然后將溶液加熱到49℃(120℉)。

　　3. Mix the mixture for a few minutes, then heat the solution to 49 ° C (120 ° f).

　　4.慢慢地將溶液通過過濾蓋或一個分支倒入管道，在那里它將開始冒泡。當化學反應停止時，熱的溶液充滿散熱器;

　　4. Slowly pour the solution through the filter cap or a branch into the pipe, where it will start to bubble. When the chemical reaction stops, the hot solution fills the radiator;

　　5.將溶液在系統中放置幾分鐘，然后從底部管道或排水管將溶液返回到原始容器中。

　　5. Place the solution in the system for a few minutes, then return the solution from the bottom pipe or drain to the original container.

　　6.檢查一下油箱的內部。如仍有水垢，重復上述步驟，使酸溶液強化至8%。

　　6. Check the inside of the tank. If there is still scale, repeat the above steps to strengthen the acid solution to 8%.

　　7.除銹后,中和酸在以下步驟:用清水填充容器,加熱到沸點,每天添加蘇打水晶,在以下比例:500 g蘇打20升水(1磅4加侖的水),把溶液倒入散熱器,讓它流回原來的容器。

　　7. After rust removal, neutralize the acid in the following steps: fill the container with clear water, heat to the boiling point, add soda crystal every day, in the following proportion: 500 g of soda 20 liters (1 pound of 4 gallons of water), pour the solution into the radiator, let it flow back to the original container.

　　8. 用上述方法沖洗散熱器幾次，然后將其放入散熱器中一小時。倒空后用熱水沖洗。

　　8. Wash the radiator several times with the above method, and then put it into the radiator for one hour. Flush with hot water after emptying.

　　焦化發電機組水箱除垢比較麻煩，水垢對柴油發電機組冷卻系統也有腐蝕，所以焦化發電機組廠家建議用戶使用廠家推薦的冷卻劑，以延發電機組的使用壽命。

　　It is difficult to remove the scale in the water tank of the coking generator set, and the scale also corrodes the cooling system of the diesel generator set. Therefore, the coking generator set manufacturer recommends that the user use the coolant recommended by the manufacturer to extend the service life of the generator set.
