叉車防凍液的作用以及選擇!

叉車防凍液的效果:防凍和冷卻防凍液的全稱為防凍冷卻液,從姓名上就可以看出它有兩項主要的功用:就是防凍,第二為冷卻。防凍液可以避免車輛在寒冷冬天停車時冷卻液結冰而脹裂車輛的冷卻系統,而在夏天則可以避免“開鍋”。 什么是開鍋?

  The effect of forklift antifreeze: antifreeze and cooling antifreeze are all called antifreeze coolant. From the name, it can be seen that it has two main functions: the first is antifreeze, the second is cooling. Anti-freezing fluid can prevent the cooling system from freezing and cracking when the vehicle stops in cold winter, and can avoid "boiling" in summer. What is boiling pot?
  咱們常說的“開鍋”是指發動機水箱中的冷卻水到達沸點,并發生很多水蒸氣,正如家中煮開水相同。由于水溫到達了沸點,會發生很多氣泡,冷卻系統中一部分面積被氣泡所占據,就會使氣缸壁周圍嚴重虧水,然后使得發動機缺乏冷卻,會使活塞、活塞環、連桿等部件的強度降低,乃至變形,承受不了正常的負荷,一起也會破壞各零件間的正常空隙,使零件間不能保持正常的油膜,輕則會使發動機拉缸、拉瓦,重則還會使整個發動機損壞乃至作廢。 此外,防凍液除了“防凍”之外,還有一個特性就是沸點高。咱們都知道水的沸點為100℃,而防凍液的沸點一般都在110-120℃,這對保護發動機、避免“開鍋”有顯著的效果。舉一個簡略的比如,桑塔納發動機的作業溫度為90-105℃,捷達為85-115℃,假如全部用水取代防凍液的話,不光不防凍,并且在夏天還容易開鍋。 防凍液除了具有“冰點低、沸點高”特點外,還具有防腐蝕和防水垢的效果。
  We often say "boiling" means that the cooling water in the engine water tank reaches the boiling point and generates a lot of water vapor, just like boiling water at home. As the water temperature reaches the boiling point, many bubbles will occur. A part of the cooling system occupied by bubbles will cause serious water shortage around the cylinder wall. Then the lack of cooling of the engine will reduce the strength of the piston, piston ring, connecting rod and other components, and even deform them, which can not withstand normal loads. Together, it will also destroy the normal voids between the parts, so that the parts will not be able to withstand normal loads. The normal oil film can make the engine pull cylinder and tile lightly, and the engine damage or even scrap heavily. In addition, in addition to "anti-freezing" antifreeze, there is also a characteristic of high boiling point. We all know that the boiling point of water is 100 C, while the boiling point of antifreeze is generally 110 - 120 C, which has a significant effect on protecting the engine and avoiding "boiling". For example, the operating temperature of Santana engine is 90-105 C and Jetta is 85-115 C. If all water is used instead of antifreeze, it is not only not antifreeze, but also easy to boil in summer. In addition to the characteristics of "low freezing point and high boiling point", antifreeze has the effect of anti-corrosion and anti-scaling.
  假如終年運用普通自來水,水中都含有礦物質成分,尤其是鈣和鎂,在高溫環境中,這些礦物質會與金屬件發生反應并形成難以去除的水垢,水垢也是車輛冷卻系統的另一大殺手。車輛冷卻系統中形成水垢后會影響“冷卻水”的流動性,一起對各部件的散熱也晦氣。久而久之便會影響車輛冷卻系統的正常作業。而假如運用專用的防凍液則沒有了這方面的顧慮,它不光具有防腐蝕性,并且在制作過程中一般都是用蒸餾水,并加入防水垢增加劑,所以水垢的問題也無需憂慮。 ● 防凍液的挑選:防凍液冰點比居住地冬天低溫再降10℃ 目前市面上的防凍液大致有兩類,一類為濃縮液,需求兌水運用。第二類,為“即買即用”型,防凍液在運用時無需兌水。此外,整車廠商還會推出原廠指定品牌防凍液,這類防凍液一般多為濃縮型,需兌水運用。而市面上出售的大部分“通用型”防凍液則多為“即買即用”型,購買是盡量挑選大品牌的產品就行了。比如殼牌、嘉實多和長城等均有對應的產品。

  If ordinary tap water is used all year round, it contains mineral components, especially calcium and magnesium. In high temperature environment, these minerals will react with metal parts and form scales that are difficult to remove. Scale is another major killer of vehicle cooling system. Scale formation in vehicle cooling system will affect the fluidity of "cooling water", and the heat dissipation of each component is also obscure. Over time, it will affect the normal operation of vehicle cooling system. However, if special antifreeze is used, there is no such concern. It is not only anticorrosive, but also used distilled water in the production process and added with water-proof scale additives, so there is no need to worry about the scale problem. Selection of antifreeze solution: The freezing point of antifreeze solution is 10 degrees lower than the lowest temperature in winter in the residential area. There are two kinds of antifreeze liquid on the market at present, one is concentrated liquid, which needs to be mixed with water. The second type is the "buy-and-use" type, and the antifreeze does not need water when it is used. In addition, the vehicle manufacturers will also introduce the original designated brand antifreeze liquid, which is usually concentrated and needs to be mixed with water. Most of the "general" antifreeze liquid sold on the market is "buy-and-use" type, and the purchase is to select the products of large brands as far as possible. For example, Shell, Jiashiduo and Great Wall have corresponding products.
  關于車主來說需求注意的就是包裝上冰點標識。如圖所示,這瓶殼牌防凍液的冰點為零下30℃。如何挑選防凍液的冰點?建議仍是參閱您實際居住地的冬天低氣溫,然后再下降10-15攝氏度為宜。寶馬華晨寶馬寶馬3系2005款 320i時髦型木內飾 防凍液的價格大多都不貴,其中“通用型”的防凍液主流品牌產品價格根本都在40-60元一桶,容量為4升(一般轎車水箱容積差不多也是4L)。原廠濃縮型防凍液的價格可能會稍貴一些,一般在80元一瓶左右,容量為1.5L左右。在替換防凍液時需按份額增加,一般狀況下為防凍液比水按照1:1或許1:2的份額即可。
  For car owners, the most important thing to pay attention to is the freezing mark on the packaging. As shown in the figure, the freezing point of this bottle of Shell antifreeze is minus 30 C. How to choose the freezing point of antifreeze? It is still advisable to refer to the lowest temperature in winter in your actual place of residence and then drop by 10-15 degrees Celsius. BMW Huachen BMW 3 Series 2005 320i fashionable wood interior antifreeze is mostly inexpensive, of which the price of "universal" antifreeze mainstream brand products are basically 40-60 yuan a barrel, capacity is 4 liters (car water tank volume is almost 4L). The price of the concentrated antifreeze may be a little more expensive, usually around 80 yuan a bottle, capacity is about 1.5L. When replacing antifreeze liquid, it needs to increase by share. In general, the proportion of antifreeze liquid to water should be 1:1 or 1:2.
