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. 1. If the ejector's suction port is closed and sealed max tight, the suction flow rate becomes "" and the vacuum pressure increases to the maximum (max). 2. 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 1 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 "" (atmospheric pressure). acuum pressure reached 89.3ka acuum pressure 1 8ka 66.7ka 53.3ka 4ka 26.7ka 13.3ka Q1 Qmax Suction flow rate When adsorbing work pieces which are permeable or subject to leakage, etc., caution is required as the vacuum pressure will not be very high.
