Introduction
This section provides engine rating classification method of air filtration device for the traditional and new forms of air filtration device grading
Efficiency measurement, the role of these air filtration device is to filter out dust in the air pollutants to protect the engine.
Fractionation efficiency is a major performance metric for air filtration units. This section is used to guide the measurement of this parameter test method. system
The purpose of this test method is to classify the air filtration unit in a prescribed laboratory test bench in accordance with a uniform test method
Test evaluation.
The data obtained in accordance with this section can be used to determine the classification efficiency characteristics of the air filtration unit tested in accordance with this method. actual
The working environment (pollutants, humidity, temperature, mechanical vibration, flow fluctuations, etc.) is difficult to be simulated, but by using this test method, you can compare
The high confidence level compares the classification efficiency of the air filtration unit.
Car engine and compressor intake air filter
Part 1. Fine particle classification efficiency test
(0.3 μm to 5 μm)
1 Scope
GB/T 35358 provisions of this part of the test method is through the use of optical diameter 0.3μm to 5μm dust to test the engine
Air filter performance.
This part of the performance test including but not limited to the air flow resistance or pressure loss, the original classification efficiency and dust holding capacity during the test increment
Grading efficiency.
The purpose of this section is to establish and provide a unified test procedures, test conditions, test equipment and performance reports, in order to be able to intake system
The air filters used in the system are compared with those of air filters. In the use of laboratory bench to air filter and air filter
This part of the conformance assessment, the test equipment, test procedures and test report format described in detail.
