Indoor airflow detection in clean room engineering


The characteristics of air flow measurement in the clean room project are large vibration. Not every air flow meter is installed in a place with high vibration. However, air flow meters installed in compression plants and blower rooms must consider vibration issues. This vibration mainly comes from compressors and blowers. The vibration of the machine can be transmitted far away through air ducts or ducts. Among them, the most reciprocating compressors are reciprocating compressors. The vibrations generated by large reciprocating compressors often cause the plant to vibrate with the surrounding ground, which threatens the accurate and reliable operation of related air flow meters. It causes the fulcrum of the lever differential pressure transmitter to move and cause the meter to drift. The vibration causes the vortex flow sensor to generate an interference signal corresponding to the vibration frequency, which causes the flow indication value to be significantly higher.
Technical parameters of clean room purification:
Ventilation times of dust-free workshop project: 10-15 times per hour for 100,000 class;
10,000 class 15-25 times / hour;
Thousands class 50-52 times / hour;
The wind speed at the section of the hundred-level operation platform is 0.25-0.35m / s;
Differential pressure: ≥5Pa from the main workshop to the adjacent clean room; ≥10Pa from the clean room to the non-clean area;
Throttle differential pressure flowmeter for clean room engineering. Throttle differential pressure flow meters have a long history in air flow measurement. With the emergence of a large number of novel flowmeters, despite the major shortcomings of narrow differential pressure flowmeters such as narrow range, troublesome installation and maintenance, and large pressure loss, it is still reliable in compressor rooms and blower rooms with obvious vibration. The instrument with high performance, good stability and strong anti-interference ability.
