At this time, read vacuum pressure P1, obtain the suction flow rate from the flow-rate characteristics graph for the ejector that is being used, and render this amount as the leakage of the workpiece.

Vs: Power supply 24VDC 12 to 15VDC One of the preset pressures P1 through P4 is selected by the ON/OFF combination of S1 and S2. S1 S2 Preset pressure OFF OFF P1 ON OFF P2 OFF ON P3 ON ON P4 For safety reasons, it is recommended that one of the preset pressures be set to 0MPa.
Pressure Momentary change P1 P2 Set value Anti-chattering function Devices such as large bore cylinders and high-flow vacuum ejectors consume a large volume of air when they operate, and this may cause a momentary drop in the primary pressure.
Mist generation pressure differential (MPa) IC EX: How to obtain the mist generating pressure differential if the flow rate obtaine in 1. above is 35 m3/min and the line pressure (inlet pressure P1) is 0.7 MPa: Extend horizontally from the point at which the flow rate is 35 m3/min to obtain the point that intersects with P1 = 0.7 MPa.

(the condition of P1 and Q1) 3. If the suction port is opened completely, the suction flow rate increases to the maximum (Qmax), while the vacuum pressure then drops almost to 0 (atmospheric pressure). When adsorbing work pieces which are permeable or subject to leakage, etc., caution is required as the vacuum pressure will not be very high.
