滤清器是自动上料搅拌车不可缺少的部件，一般包括空气滤清器、燃油滤清器两种，今天就和大家简单介绍一下这两种滤清器，也是为了方便后期的使用和维修。

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.

空气滤清器

Air filter

空气滤清器一般安装在发动机进气管前方的进气系统中，其主要作用就是滤掉将要进入气缸的空气中的有害杂质，以减少气缸、活塞、活塞环、气门及气门座的早期磨损，提高发动机的耐久性，根据结构形式分为干式和湿式两种，湿式空气滤清器又包括油浸式和油浴式两种。

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.

我们要对空气滤清器的工作原理有所了解，混凝土搅拌机启动时，发动机在吸入空气和燃油混合之前，空气滤清器的功能就是滤掉空气中的灰尘、碳、部分的水蒸气及其它的杂物，从而保证清洁的空气进入到气缸中。在理论上每单位体积的燃油燃烧时，大约需要1万单位体积的清洁空气。一般情况下，制造商空气滤清器正常维护的更换周期为4.8万Km,且每2.4万Km要进行一次常规检查；所以保守的维护更换周期为2.4万KM，混凝土搅拌机所处的工作环境比较差，维护周期要相应的减少一些。

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.

在大气中含有三种密度不同的基本颗粒污染物，即灰尘、残渣和碳粒。如果是在开放式的高速公路上，灰尘的含量较建筑工地低一些，灰尘浓度较大的区域，即建筑工地，搅拌站，风沙区域，在这些地方工作的混凝土搅拌机，它的空气滤清器的检验和更换频率要高一些；而在高速公路和交通比较拥堵的区域，因为车辆的排放物集中，所以空气中碳的含量明显偏高，对于滤清器的检查更应该仔细，尤其是滤清器的内部褶皱处；有时候，滤清器的外部看似清洁，但是其实内部已经非常脏了，因此必须尽快更换。

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.

燃油滤清器

Fuel filter

燃油滤清器属于燃油的过滤装置，有柴油滤清器和机油滤清器两种，它串联在燃油泵和节流阀体进入油口之间管路上，一般都在发动机共轨系统的一侧，通过它可以得到更的柴油，从而保护发动机的正常工作，减少磨损，避免堵塞，提高自动上料搅拌车发动机使用寿命。它的作用主要有两个：过滤固体有害杂质；过滤燃油中的水分。

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.
