5. vacuum system circuit diagram     The vacuum circuit diagram list of components 1. THE VACUUM EJECTOR PUMP      If compressed air (4-6BAR) is supplied to an  AIR-type EJECTOR PUMP,     the VENTURI phenomenon will occur on the nozzles arranged in  parallel and will     instantly generate a vacuum at the  vacuum nozzle 2. THE SOLVAC AIR SAVING SYSTEM (AS-KIT)     This is a system that can dramatically save air  consumption by automatically     blocking air if a  vacuum reaches a certain degree. 3. THE VACUUM ON/OFF CONTROL VALVE     This is a valve that links and blocks air supply to the vacuum pump.     Various types of valves can be selected including solenoid, roller lever, and  hand valves. 4. THE VACUUM RELEASE CONTROL VALVE     This is a valve that releases the generated vacuum. 5. THE NEEDLE VALVE     This is a valve that controls flow. 6. THE VACUUM FILTER     This filters out foreign matter and dust in order to prevent them from flowing into the     vacuum pump.     In order for the vacuum pump to function properly,  the use of a vacuum filter is essential. 7. THE VACUUM GAUGE     This displays the degree of the vacuum.. 8. THE VACUUM SWITCH     This delivers electronic or air compressing signals     when a vacuum reaches a certain degree. 9. THE SPRING PLUNGER     This controls the difference between the heights of objects to be conveyed. 10. THE BALL JOINT     If an inclined object is to be conveyed, the ball joint  would work so that a vacuum     pad can be attached along the incline. 11. THE VACUUM PAD     This is attached to the surface of an object. 12. THE FILTER REGULATOR     This removes foreign matter from the compressed air supplied and maintains a     certain level of pressure.. 13. THE HAND-OPERATED VALVE     This is a valve for hand operation.
