大修过汽车发动机的人都知道，拆开发动机里面的水道有一层一层的水垢，水道壁锈迹斑斑，那怎么减缓发动机产生水垢及铁绣呢？
济南哪里修奥迪比较厂家为您讲解。
Anyone who has overhauled an automobile engine knows that the water channel inside the engine has layers of scale and the water channel wall is rusty. How can we slow down the water scale and iron rust produced by the engine? Where to repair Audi in Jinan? The professional manufacturer will explain it to you.
水垢和铁锈产生的原因
Causes of scale and rust
铁锈是水、铁、氧三者起氧化作用的结果。由于水套内有形成铁锈的条件：一，水套本身是铸铁制造的；二，水本身含有氧气，加之散热器水面低于水套时，水套内就进入空气，这些都是形成铁锈的条件。
Rust is the result of oxidation of water, iron and oxygen. As there are conditions for rust formation in the water jacket: first, the water jacket itself is made of cast iron; 2、 The water itself contains oxygen, and when the water surface of the radiator is lower than the water jacket, air will enter the water jacket, which are the conditions for the formation of rust.
当发动机运转后，机体温度升高，更加加速了氧化锈蚀。冷却水是硬水时，水中含有矿物质。当温度升高后，这些矿物质就沉淀，形成水垢。如加软水就不会形成水垢。
When the engine runs, the temperature of the engine body rises, which accelerates the oxidation and corrosion. When the cooling water is hard, it contains minerals. When the temperature rises, these minerals precipitate and form scale. If soft water is added, scale will not be formed.
防止发动机产生水垢及铁绣的措施：
Measures to prevent engine from scaling and iron rust:
加防锈剂；
Add anti rust agent;
尽可能加软水，加自来水也可；
Add soft water or tap water as much as possible;
保持散热器水面高度，防止空气进入水套，以便减少铁锈的产生；
Keep the water surface height of the radiator to prevent air from entering the water jacket, so as to reduce the generation of rust;
为保护冷却系统，好使用防冻液，否则寒冷天气水结冰易胀破水套；
To protect the cooling system, it is better to use antifreeze, otherwise the water jacket will be easily broken when the water freezes in cold weather;
应防止散热器漏水，减少加水次数，同时应减少换水次数，防止产生过多的水垢。
The radiator shall be prevented from leaking, the number of water additions shall be reduced, and the number of water changes shall be reduced to prevent excessive scale.
产生水垢和铁锈，在水套内壁和水之间会形成隔热膜，由于其导热性很差，将大大降低冷却效果，发动机产生的热量无法散发出去，不利于其性能的稳定发挥。
Scale and rust will be generated, and a thermal insulation film will be formed between the inner wall of the water jacket and the water. Due to its poor thermal conductivity, the cooling effect will be greatly reduced, and the heat generated by the engine cannot be dissipated, which is not conducive to its stable performance.
After we understand the causes of scale and rust, we can start to prevent it, reduce the recurrence of such situations, and protect the engine. Come to our website for more information http://www.lutongqixiu.com Consult!
