Furring car header tank water system caused by poor water, can not effectively heat output of cooling the body; body water side fouling, due to scale thermal resistance coefficient, the formation of a cooling barrier, both resulting in body temperature rises and coexist. After the body temperature rises, the piston lubricant consistency diluted, lost lubrication, resulting in high temperature piston, friction increases at high temperatures change the physical properties of the metal, it has also undergone a chemical change, caused by fuel waste. Leading to serious engine locking, stick cylinder, of the tile, the consequences of leaks and other damage, and even cause accidents.
The car header tanks have been removed hose with water and compressed air cleaning the exterior dirt, then placed in the sink to remove scale. car header tank descaling method:
1. Will be filled within the sink containing 3 to 5% sodium carbonate aqueous solution, the heating, the temperature is maintained at 80 to 90C; the water car header tank placed in a sink detergent, after about 5 to 8 hours out, into the water in the pool, and then warm water;
2. Will be filled on a sink containing 10 to 15% of the caustic soda solution heated to a digester car header tank where 25 to 30 minutes, then washed with hot water;
3. On the scale of serious water car header tank, can be 3 to 5% hydrochloric acid solution, according to a liter of solution by adding 3 5 g hexamethylene tetramine, then heated to 60 to 70 ℃, washing for about 30 minutes; then hot lye wash, and finally rinse with water;
4. When the car header tank through the above methods can not remove scale, use a soft metal cleaning rod dredge to remove deposits. Then press the above method to clear again. The car header tanks have been removed hose with water and compressed air cleaning the exterior dirt, then placed in the sink to remove scale.
