After the machine is used for a period of time, scale is inevitable. In particular, the scales of the cylinder head, the cylinder water jacket, and the water tank interfere with heat dissipation and should be promptly removed. The main methods of cleaning the cooling system are: 1. Alkaline washing method: The steps are: (1) Start the engine at medium speed so that the water temperature rises above 50°C, turn off the cooling water; (2) Add 1.5 kg of caustic soda and 0.5 kg of kerosene to 20 kg of water. The cleaning fluid is injected into the water tank; (3) Start the engine for 5 to 10 minutes to stop the engine for 10 hours; (4) Restart the engine to control the speed of the throttle so that the speed of the rotation is fast and slow to make the water flow shock wave to allow the scale or sediment to suspend the operation 5 to 10 After a few minutes, make up the cleaning solution; (5) Add clean, soft water to the tank to start the engine for 5 minutes and then drain the washing water for 2 to 3 times. 2. Pickling method: Inject 20% hydrochloric acid solution into the tank for 10 minutes, release the cleaning solution and rinse it with clean water. Note: When preparing the hydrochloric acid solution, slowly pour the hydrochloric acid into the water and stir constantly. Do not pour the water into the hydrochloric acid. Whether the pickling or caustic washing is corrosive to the metal, it is necessary to grasp the ratio of the cleaning liquid and the cleaning time. Finally rinse with clean water several times. In order to avoid the corrosion of the cooling system by the general chemical cleaning solution, a special “water tank cleaning agent†can also be used. The method of use is the same as the above-mentioned alkaline cleaning method.
