引射系统在空气滤清器性能试验中的实践

所谓引射排尘式空气滤清器就是利用发动机的排气,形成一股引射气流,强制排出粗滤器滤出的灰尘。对引射系统在空气滤清器性能试验过程中的细节作了详细介绍,对某相同型号的具有引射排尘式空气滤清器安装引射系统和未安装引射系统两种形式进行了粗滤效率试验并作了对比分析,总结了一些技术要点,归纳了引射系统在空气滤清器性能试验中不可取代的重要性。

Scavenged System Applying in Air Filter Performance Test

The air fiher torte discharge the dust fihered by the precleaner, using a scavenged airflow that made by the motor exhausting. That is scavenged air fliter. The details about scavenged system applying in air filter performance test were introduced, and compared the pre- cleaner efficiency result between two same type scavenged air filter which one air fiher with scavenged system and another without. At last some technologic key point was given, and it was sununarized the scavenged system is very important cannot replaced in air filter performance test.
