Many people come to find out that they have problems when it comes to vacuuming powder. Especially drying fine powder that tends to get puffed up and pulled into the vacuum pump flooding it. With the pumps flooded this leads to an unfortunate problem, one you end up losing the powders you’re trying dry and two it isn’t the best for your pump either.
Why do I care about slew rate? In a critical process it may be necessary to slowly bring the vacuum level up or down at a specified rate so as to not disturb process material. This can be referred to as the slew rate, or ramp rate, of the vacuum level. A new feature for the Stratavac Touch is the ability to set a slew rate along with a setpoint for a valve and the controller handles the details. In Vacuum, what we mean by slew rate is a specific or defined change in pressure over a defined timeframe. Some people
Benefits of Throttle and Bleed Vacuum Control The most commonly used vacuum pumps run at one speed. Therefore, the pump is always driving toward the deepest vacuum control level possible where they function optimally. Just because this is the sweet spot for your vacuum pump, doesn’t mean it’s the best vacuum level for your process. Applications of vacuum technology take place over a wide range of vacuum from ultra-high vacuum all the way up to atmosphere. Most often for industrial vacuum processing, users are ideally looking for a vacuum level that differs from the ultimate pressure of a pump; therefore,
