SUMMARY

The discussion centers on troubleshooting pressure gauge issues in a compressed air machine, specifically a cigarette filter maker. The pressure gauges are malfunctioning when attached to the machine, but function correctly on other lines. Key factors include the absence of an air tank, the pressure range of the machine (10mbar to 130mbar), and the gauge's range (0mbar to 180mbar). Potential causes for the malfunction include blockages in the air line, closed isolation valves, or inadequate pressure supply.

PREREQUISITES
  • Understanding of compressed air systems and their components
  • Familiarity with pressure gauge specifications and ranges
  • Knowledge of troubleshooting techniques for pneumatic systems
  • Basic mechanical skills for handling and inspecting equipment
NEXT STEPS
  • Investigate the impact of blockages in air lines on pressure readings
  • Learn about the function and importance of isolation valves in pneumatic systems
  • Research the specifications and operational ranges of pressure gauges
  • Explore troubleshooting methods for compressed air machinery
USEFUL FOR

Technicians, engineers, and maintenance personnel working with compressed air systems, particularly those involved in the operation and troubleshooting of pneumatic machinery.

hi every body,

I have a machine with compressed air. the problem is the pressure gauges is not working.
and when I take the gauges into other compressed air line the pressure gauge work properly.
why this happening ? I need your help
 
Engineering news on Phys.org
Here are some thoughts. Where is gage attached on the machine in question. What is the machine. Does it have an air tank etc. What range of pressure is the machine supposed to operate at. Is this range suitable for the gage.
 
There is a blower pump ( pump pressure= 250mbar) . the air of blower pass throw manifold into three ports. the gauges attached after manifold in each port to measure the pressure of each port. (No Air Tank)
The range of pressure for each port is from (10mbar to 130mbar) , the pressure gauge range is (0mbar - 180mbar)
The machine is cigarette filter maker

anther Question.
I found in pump specification [pressure= +(250/230)mbar] . what does it mean? Max &min??

The gauge might be working OK. Do you really have pressure?
Or do you have pressure and a block in the air line to the gauge?
Is there an isolation valve on the line to the gauge that has been closed?
When you remove the gauge, does it release air?
