的流动特性表明真空度之间的关系
压力和喷射器的吸入流速，并表明，当
吸气流速改变真空压力也会改变。一般情况下，
这表明喷射器的标准工作压力的关系。
在该曲线图中，P表示的真空压力，尿流率（Qmax）
表示的的吸引流率。这些的值

解释如下。
1。如果喷射器的吸入口的关闭和密封
紧，吸气流率变为“0”和
真空压力增加到

增大，真空压力降低。
（P1和Q1的条件）
3。如果完全打开的吸入口，
吸引流率增加到
尿流率（Qmax），然后真空压力下降

Specific Product Precautions 1
Be sure to read before handling.
Refer to front matters 38 and 39 for Safety Instructions and pages 844 to 846 for Vacuum
Equipment Precautions.
Operation of Ejector Valves
Caution
1. When the air supply is turned ON, vacuum is generated by
the flow of compressed air from the nozzle to the diffuser.
When the vacuum release is turned ON, the vacuum is quickly
released as air passes through the release flow adjustment
needle and flows to the vacuum port.
Operating Environment
Caution
1. Avoid use exposed to direct sunlight.
Solenoid Valves (Series ZL112)
Caution
1. For specific product precuations on solenoid valves, refer
to the solenoid valve (Series SYJ500) catalog.
<How to Read the Graph>
The flow characteristics indicate the relationship between the vacuum
pressure and the suction flow rate of the ejector, and show that when the
suction flow rate changes the vacuum pressure also changes. In general,
this indicates the relationship at the ejector’s standard operating pressure.
In the graph, Pmax 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
tight, the suction flow rate becomes “0” and the
vacuum pressure increases to the maximum
(Pmax).
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 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.
