關于叉車發動機積碳的清除方法

來源:http://nukkadh.com/ 日期:2018-09-17 發布人:admin

方法一、叉車機械法:是采用鋼絲刷、刮刀、竹片或砂布來清除積炭的方法。可按照零件清洗部位的形狀做成專用刷子和刮刀:如對噴油器噴孔周圍的積炭,可用細銅絲刷刷凈;對壓力室的積炭可用銅絲做成的專用通針插入以刮凈;對氣門導管、氣門座的積炭,可用圓柱形金屬刷來清除。

Methods 1. Forklift mechanical method: Wire brush, scraper, bamboo or abrasive cloth to remove the coke method. It can be made into special brushes and scrapers according to the shape of parts cleaning parts: for example, the coke deposited around the nozzle hole of the injector can be brushed with thin copper wire; for the coke deposited in the pressure chamber, a special through needle made of copper wire can be inserted to scrape off; for the coke deposited in the valve duct and valve seat, a cylindrical metal brush can be used to remove it.
機械法清除積炭工效低、清除質量差,有些部位難以刮除干凈,還會留下許多細小劃痕,成為新積炭的生長點,增大了零件的粗糙度。因此,對精度高的零件一般不宜采用此法。
The mechanical method is inefficient in removing coke deposit, poor in quality, difficult to scrape some parts clean, but also leave many small scratches, become the growth point of new coke deposit, increased the roughness of parts. Therefore, this method is not suitable for parts with high accuracy.

方法二、噴核法:是利用高速氣流將粉碎的核桃、桃、杏的桃殼顆粒噴向零件表面以去除積炭的方法。此法除積炭的效率高、徹底干凈,但需要有形成高速氣流的專用設備,成本相對較高,因此也不宜廣泛采用。
Method 2. Spraying core method: The peach shell particles of walnut, peach and apricot were sprayed onto the surface of parts by high-speed airflow to remove the coke deposit. This method is efficient and thoroughly clean for removing coke deposit, but it needs special equipment to form high-speed airflow, and the cost is relatively high. Therefore, it is not suitable to be widely used.
方法三、化學法:是使用一種化學溶劑——退炭劑將零件表面的積炭軟化,使其失去與金屬結合的能力,然后將軟化的積炭除去的方法。此法除積炭的效率高、效果好,不易損環零件表面。退炭劑一般由積炭溶劑、稀釋劑、緩成釋劑和活性劑4種成分組成。退炭劑的種類較多,按金屬零件材質的不同可分為鋼件退炭劑和鋁件退炭劑,上些退炭劑中含有對鋁制品起化學腐蝕作用的成分(如苛性鈉),所以只適用于鋼件退炭。
Method 3. Chemical method: It uses a chemical solvent - decarbonizer to soften the coke deposit on the surface of the parts, making it lose the ability to combine with metal, and then remove the soft coke. This method has high efficiency and good effect except carbon deposition, and it is not easy to damage the surface of ring parts. Carbon removal agents are generally composed of 4 components: carbon deposition solvent, diluent, slow release agent and active agent. There are many kinds of decarburizers, which can be divided into steel decarburizers and aluminum decarburizers according to the different materials of metal parts. Some decarburizers contain chemical corrosion components (such as caustic soda), so they are only suitable for steel parts decarburization.
