50年代开始发展起来的新型干式纸质空气滤清器,发展历史虽不长,因具有很多优点,在国外汽车上(特别是轿车上)早就采用。至今,纸质空滤器发展的种类也比较多,如:带旋流叶片的单滤芯空滤器,带旋流叶片环的双滤芯空滤器,旋流管加单滤芯或双滤芯的,以及采用双寿命滤纸和锥形滤芯的等等。我厂X6130及其增压柴油机是采用带有旋流叶片环双滤芯的三级滤清纸质干式空气滤清器(如图1)。兹阐述设计方法和在设计中所要注意 The new dry-paper air filter, which started to develop in the 1950s, has not long history of development. It has long been adopted in foreign vehicles (especially on cars) because of its many advantages. So far, the development of paper air filter is also more types, such as: a single-cartridge air filter with a swirling vane, a double-filter air filter with a swirling vane ring, a single or dual filter cartridge with a spiral pipe, Life filter paper and cone filter and so on. Our factory X6130 and its turbocharged diesel engine are three-stage filter paper dry air filter (as shown in Figure 1). Here are the design methods and design considerations
