In general, this indicates the relationship at the ejector s standard operating pressure. In the graph, max indicates the maximum vacuum pressure, and Qmax indicates the maximum suction flow rate. These are the values that are published as specifications in catalogs, etc. Changes in vacuum pressure are explained below. max. If the ejector s suction port is closed and sealed tight, the suction flow rate becomes and the vacuum pressure increases to the maximum (max).. If the suction port is opened and air is allowed to flow (the air leaks), the suction flow rate increases and the vacuum pressure decreases. (the condition of and Q) 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 (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. A Z S AM AE HE 7

Series Specific roduct recautions Be sure to read before handling. Refer to front matters 38 and 39 for Safety Instructions and pages 844 to 846 for acuum recautions. Operation of Ejector alves Caution. When the air supply valve is turned ON, vacuum is generated by the flow of compressed air from the nozzle to the diffuser. When the vacuum release valve is turned ON, the vacuum is quickly released as air passes through the release flow adjustment needle and flows to the vacuum port. Caution Caution Operating Environment. Avoid use exposed to direct sunlight. Solenoid alves (Series ). For specific product precuations on solenoid valves, refer to the solenoid valve (Series SYJ5) catalog. A Z S AM AE HE 79
