Theory of Operation

Venturi Vacuum Pumps with Air Saver Technology


The Vaccon Air Saver Circuit is an all-pneumatic system designed to minimize compressed air usage in vacuum clamping and vessel evacuation applications.

For pick and place applications handling non porous materials, the Air Saver Circuit will maintain a safe holding force, save compressed air and hold the part even if the compressed air supply is interrupted providing an extra level of safety when handling large loads.

This complete system requires only a compressed air source to be fully functional. The system includes a venturi vacuum pump, vacuum check valve, air piloted air valve and pneumatic vacuum switch. The pneumatic vacuum switch is the brain of the system that constantly monitors the vacuum level. The vacuum switch is adjustable from 0 to 30"Hg and is set using the adjustment knob.

The hysteresis is set at approximately 3"Hg. Simply set the switch to the desired vacuum level and should there be a leak in the system and the vacuum level drops by set at approximately 3"Hg, the Air Saver Circuit automatically re-energizes the venturi to bring the system back to the preset vacuum level and then de-energizes the venturi. The vacuum check valve seals the system.

The Vaccon Air Saver Technology has been adapted to the entire range of Vaccon venturi vacuum pumps. These are ideal for creating and maintaining vacuum for safe, energy efficient operations for clamping, pick and place and vessel evacuation applications.

Principles of Operation: Air Saver Pumps

The pneumatic vacuum switch is the brain within the Air Saver system. It constantly monitors and controls the vacuum level as required based on customer specifications. Minimizing leaks in plumbing lines and connections extends the "venturi off" cycle and maximizes air savings. Below is a brief overview of the air saver cycle.

 Air Saver Principles of Operation-50

    Determine the maximum vacuum level desired, then adjust the switch to the vacuum level setpoint.

   1. Once the vacuum level set-point is reached, the switch turns the pump off, stopping the flow of air to
       the venturi → air savings.

   2. The integral check valve maintains the vacuum level.

   3. Should there be a leak and the vacuum level decrease (Hysteresis 3"Hg [102mbar]), the pneumatic  
       switch automatically re-energizes the venturi to bring the system back to the pre-set vacuum level 
       set-point.

   4. Then the switch de-energizes the venturi pump, (stopping the flow of air to the venturi — air savings) 
       and the air saving cycle starts again.

 

Air Saver VP20-100H-AS-15                       

VP20-AS Mid Series:   Venturi Vacuum Pumps with Air Saver Technology

Vaccon's Air Saver Pumps are an all-pneumatic systems that minimizes compressed air usage by creating, monitoring and maintaining vacuum for safe energy efficient operations.

For pick and place applications handling non-porous materials, the Air Saver pumps will maintain a strong holding force, conserve compressed air, and hold the part even if the compressed air supply is interrupted providing an extra level of safety when handl-ing large loads.

For vessel evacuation applications such as wood and composite clamping, Air Saver pumps maintain vacuum for long periods of time and only consume compressed air to overcome system leaks resulting in 90% air savings.

The system includes a venturi vacuum pump, vacuum check valve, air piloted air valve and all-pneumatic vacuum switch. The switch is adjustable from 0 to 28"Hg [948mbar] and the hysteresis is set at approximately 3"Hg [102mbar].
