Pneumatic conveying troubleshooting: What your pressure gauge can tell you — and more, 1/14
CD of live broadcast 1/7/14
This webinar focuses on troubleshooting pneumatic conveying systems. In the past, we’ve covered the various types and modes of pneumatic conveying systems and equipment. The approach in this webinar is different in that we look at the conveying system as though we were a pressure gauge. Through those "eyes" we explain the potential reasons and corrective actions for the various conditions we see taking place in the conveying system.
This webinar looks primarily at dilute-phase pneumatic conveying systems using a rotary airlock as the line charger and a positive-displacement blower as the gas supply, because that’s the most common system type installed in most plants. As appropriate, we discuss other line chargers, such as pressure tanks and screw pumps.
Conditions we discuss include the following:
- A "spiked" pressure gauge
- A fluctuating pressure gauge
- A low pressure situation
- A high pressure situation
- Two gauges reading differently
- A pressure gauge in the wrong position
- A pressure gauge that needs some help
We also discuss methods of making a preliminary assessment of what may be wrong with a system and provide detailed solutions to specific hardware problems.
While not absolutely necessary, we recommend that if you’re not very familiar with dilute-phase conveying, you view our previous webinar sessions dealing with dilute-phase pneumatic conveying and troubleshooting. These can be found in our bookstore.
