When the air quality is poor, some people will wear masks to filter impurities in the air. The mixer also has a "mask", that is, an air filter. When will the air filter of the mixer be replaced?
To understand the working principle of the air filter, the function of the air filter is to filter out the dust, carbon, part of the water vapor and other impurities in the air before the engine inhales air and mixes fuel when the mixer is started, so as to ensure that clean air enters the cylinder.
In theory, 10000 units of clean air are required for the combustion of fuel per unit volume. In general, the manufacturer recommends that the replacement cycle for normal maintenance of the air filter is 48000 km, and a routine inspection should be carried out every 24000 km; Therefore, the conservative maintenance and replacement cycle is 24000 km, and the working environment of the mixer is relatively poor, so the maintenance cycle should be reduced accordingly.
There are three basic particulate pollutants with different densities in the atmosphere, namely dust, residue and carbon particles. If it is on the open expressway, the dust content is lower than that of the construction site, and the areas with higher dust concentration, namely the construction site, mixing plant, and wind blown sand area, the inspection and replacement frequency of the air filter of the mixer truck working in these areas should be higher.
However, in the expressway and areas with heavy traffic, the carbon content in the air is obviously high because of the concentration of emissions from the mixer, so the filter should be checked more carefully, especially the internal wrinkles 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.
The working place of the mixer is usually the mixing station and construction site with heavy dust. Its air filter is particularly important, and its maintenance should be very careful, otherwise it will cause abnormal wear of the engine and reduce the service life of the engine. Therefore, regular inspection, maintenance and replacement should be carried out. Please visit our website for precautions http://www.qzt12580.com consulting service
