flow regulating in the vacuum system
flow regulating in the vacuum system
(OP)
What's the flow ragulator for vacuum? My system is
Particle source -> filter -> valve -> vacuum pump.
The flow rate is about 1 acfm. While the particulate is captured by filter, the pressure drop is increased. To maintain the flow rate, the valve should be opened gradually. Is there a type of regulator that I can use between filter and vacuum pump?
The particles are less than 1 miron coal ash, actually, the purpose of this system is collecting the particles for other experiment. The valve or pressure regulator should locate after filter.
Thanks in advance

RE: flow regulating in the vacuum system
How about:
Particle source -> filter-->Vacuum Breaker-->Valve fully open-> vacuum pump
You might want to monitor the vacuum upstream of the filter as an indicator of the particulate resistance at the filter.
