濾清器是自動上料攪拌車不可缺少的部件，一般包括空氣濾清器、燃油濾清器兩種，今天就和大家簡單介紹一下這兩種濾清器，也是為了方便后期的使用和維修。

Filter is an indispensable part of automatic feeding mixer, which generally includes air filter and fuel filter. Today, I will briefly introduce these two filters to you for the convenience of later use and maintenance.

空氣濾清器

Air filter

空氣濾清器一般安裝在發動機進氣管前方的進氣系統中，其主要作用就是濾掉將要進入氣缸的空氣中的有害雜質，以減少氣缸、活塞、活塞環、氣門及氣門座的早期磨損，提高發動機的耐久性，根據結構形式分為干式和濕式兩種，濕式空氣濾清器又包括油浸式和油浴式兩種。

The air filter is generally installed in the air intake system in front of the engine intake pipe. Its main function is to filter out the harmful impurities in the air that will enter the cylinder, so as to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat and improve the durability of the engine. According to the structural form, the air filter is divided into dry type and wet type. The wet air filter also includes oil immersed type and oil bath type.

我們要對空氣濾清器的工作原理有所了解，混凝土攪拌機啟動時，發動機在吸入空氣和燃油混合之前，空氣濾清器的功能就是濾掉空氣中的灰塵、碳、部分的水蒸氣及其它的雜物，從而保證清潔的空氣進入到氣缸中。在理論上每單位體積的燃油燃燒時，大約需要1萬單位體積的清潔空氣。一般情況下，制造商推薦空氣濾清器正常維護的更換周期為4.8萬Km,且每2.4萬Km要進行一次常規檢查；所以保守的維護更換周期為2.4萬KM，混凝土攪拌機所處的工作環境比較差，維護周期要相應的減少一些。

We need to understand the working principle of the air filter. When the concrete mixer is started, the function of the air filter is to filter the dust, carbon, part of the water vapor and other sundries in the air before the engine inhales the air and mixes the fuel, so as to ensure that the clean air enters the cylinder. In theory, about 10000 units of clean air are required per unit volume of fuel combustion. Generally, the manufacturer recommends that the replacement cycle of air filter for normal maintenance is 48000 km, and routine inspection shall be conducted every 24000 km; Therefore, the conservative maintenance and replacement period is 24000km. The concrete mixer is in a poor working environment, so the maintenance period should be reduced accordingly.

在大氣中含有三種密度不同的基本顆粒污染物，即灰塵、殘渣和碳粒。如果是在開放式的高速公路上，灰塵的含量較建筑工地低一些，灰塵濃度較大的區域，即建筑工地，攪拌站，風沙區域，在這些地方工作的混凝土攪拌機，它的空氣濾清器的檢驗和更換頻率要高一些；而在高速公路和交通比較擁堵的區域，因為車輛的排放物集中，所以空氣中碳的含量明顯偏高，對于濾清器的檢查更應該仔細，尤其是濾清器的內部褶皺處；有時候，濾清器的外部看似清潔，但是其實內部已經非常臟了，因此必須盡快更換。

There are three basic particulate pollutants with different densities in the atmosphere, namely dust, residue and carbon particles. If it is on an open highway, the dust content is lower than that of the construction site, and the dust concentration is higher in the areas, i.e. the construction site, the mixing plant, and the sandstorm area. The inspection and replacement frequency of the air filter of the concrete mixer working in these areas should be higher; In areas with highways and traffic congestion, the carbon content in the air is obviously high due to the concentration of vehicle emissions. Therefore, the filter should be inspected more carefully, especially at the internal folds of the filter; Sometimes, the outside of the filter looks clean, but the inside is very dirty, so it must be replaced as soon as possible.

燃油濾清器

Fuel filter

燃油濾清器屬于燃油的過濾裝置，有柴油濾清器和機油濾清器兩種，它串聯在燃油泵和節流閥體進入油口之間管路上，一般都在發動機共軌系統的一側，通過它可以得到更優質的柴油，從而保護發動機的正常工作，減少磨損，避免堵塞，提高自動上料攪拌車發動機使用壽命。它的作用主要有兩個：過濾固體有害雜質；過濾燃油中的水分。

The fuel filter belongs to the fuel filter device, including diesel filter and engine oil filter. It is connected in series on the pipeline between the fuel pump and the oil inlet of the throttle body. It is generally on the side of the engine common rail system. Through it, higher quality diesel can be obtained, so as to protect the normal operation of the engine, reduce wear, avoid blockage and improve the service life of the engine of the automatic feeding mixer. It has two main functions: filtering solid harmful impurities; Filter the water in the fuel.
