Compressed air detection - solid particle dust particle testing

Compressed air detection-Solid particle dust particle testingUsing a high flow dust particle counter in conjunction with original compressed gas specialized detection accessories—Compressed gas diffuser (high-pressure separator), detectable0.35~10.54Compressed gas within the pressure range.

Dust particle counter connection: After the pipeline is blown clean, adjust the flow rate of the compressed air detector to be consistent with the sampling flow rate of the dust particle counter; Connect the sampling port for dust particles with a trachea.

Sampling point determination:

Compressed air detection - solid particle dust particle testing（ Suspended particle detection）The number and distribution of sampling points should be set in key operating areas according to the production process of the product. Therefore, for the determination of suspended particles in compressed air, a sampling point should be set at the end of the gas supply pipeline and at the inlet of the gas supply valve connected to the gas equipment, with a distance of 300About millimeters.

1.Test points

Only by controlling the sampling amount of compressed air can the dust concentration be calculated.

2The test condition is that the gas source has been basically filtered.

Before testing, it is necessary to deflate the air10About minutes.

3Sampling process

3.1Prepare the laser particle counter and compressed air collector properly.

3.2Particle counter startup preheating5Connect the sampling port to the self-cleaning port using a hose in minutes for self-cleaning(Wipe and disinfect with alcohol swab)Connect the high-pressure separator to the compressed air sampling point, blow gas for a period of time to stabilize it, and the particle counter will self clean

Connect the sampling port to the high-pressure air separator for sampling. Use gas source to pass through the collector first2minute

3.3Adjust the flow rate of the collector and turn on the laser particle counter.

3.4Adjust the flow rate and set the sampling period. Press the print button, and the print indicator light will turn on, indicating that the measurement results can be automatically printed after the detection cycle ends.
