Hello,
I am new here and working with pumps for the first time. We are currently working on a consumer goods product that utilizes a small d/c diaphragm motor for applying a vacuum. Right now, between cycles, the solenoid valve returns pressure to 0 between each cycle. I am wondering if anyone has tried maintaining a baseline pressure, where you would drop the vacuum to between -50 and -75mmHg instead of 0, and then resume another vacuum cycle.
Any tips on how to achieve this would be appreciated. Keep in mind it is a price conscious product, so very expensive pressure switches might be too far out of the scope. I am hoping it can be achieved by a simple motor sensor and/or by just closing the valve quicker, but maybe that's too naïve, not sure.
