大修過汽車發動機的人都知道，拆開發動機里面的水道有一層一層的水垢，水道壁銹跡斑斑，那怎么減緩發動機產生水垢及鐵繡呢？
濟南哪里修奧迪比較專業廠家為您講解。
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.
水垢和鐵銹產生的原因
Causes of scale and rust
鐵銹是水、鐵、氧三者起氧化作用的結果。由于水套內有形成鐵銹的條件：一，水套本身是鑄鐵制造的；二，水本身含有氧氣，加之散熱器水面低于水套時，水套內就進入空氣，這些都是形成鐵銹的條件。
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.
當發動機運轉后，機體溫度升高，更加加速了氧化銹蝕。冷卻水是硬水時，水中含有礦物質。當溫度升高后，這些礦物質就沉淀，形成水垢。如加軟水就不會形成水垢。
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.
防止發動機產生水垢及鐵繡的措施：
Measures to prevent engine from scaling and iron rust:
加防銹劑；
Add anti rust agent;
盡可能加軟水，加自來水也可；
Add soft water or tap water as much as possible;
保持散熱器水面高度，防止空氣進入水套，以便減少鐵銹的產生；
Keep the water surface height of the radiator to prevent air from entering the water jacket, so as to reduce the generation of rust;
為保護冷卻系統，好使用防凍液，否則寒冷天氣水結冰易脹破水套；
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;
應防止散熱器漏水，減少加水次數，同時應減少換水次數，防止產生過多的水垢。
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.
產生水垢和鐵銹，在水套內壁和水之間會形成隔熱膜，由于其導熱性很差，將大大降低冷卻效果，發動機產生的熱量無法散發出去，不利于其性能的穩定發揮。
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.junwumy.com Consult!
