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?

　　发电机组的除垢工作可按以下步骤进行:

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

　　1.从冷却系统排水，从柴油发电机连接处拆卸管道;

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

　　2.准备4%除锈酸溶液和清水。将酸性溶液按比例倒入干净的水中。

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

　　3.让混合物混合几分钟，然后将溶液加热到49℃(120℉)。

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

　　4.慢慢地将溶液通过过滤盖或一个分支倒入管道，在那里它将开始冒泡。当化学反应停止时，热的溶液充满散热器;

　　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.将溶液在系统中放置几分钟，然后从底部管道或排水管将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.检查一下油箱的内部。如仍有水垢，重复上述步骤，使酸溶液强化至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.除锈后,中和酸在以下步骤:用清水填充容器,加热到沸点,每天添加苏打水晶,在以下比例:500 g苏打20升水(1磅4加仑的水),把溶液倒入散热器,让它流回原来的容器。

　　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. 用上述方法冲洗散热器几次，然后将其放入散热器中一小时。倒空后用热水冲洗。

　　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.

　　焦化发电机组水箱除垢比较麻烦，水垢对柴油发电机组冷却系统也有腐蚀，所以焦化发电机组厂家建议用户使用厂家推荐的冷却剂，以延发电机组的使用寿命。

　　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.
