How to Read Flow Rate Characteristics Graphs

The flow rate characteristics show the relationship between the vacuum pressure and the suction flow rate of the ejector. It also shows that as the suction flow rate changes, so too does the vacuum pressure. Generally, the relationship shown is at the standard working pressure for the ejector. In the diagram, Pmax denotes the maximum vacuum pressure, and Qmax denotes the maximum suction flow rate. These values are the values listed as the specifications in the manufacturer's catalog and elsewhere. See below for information on how to change the vacuum pressure.

Generally, the relationship shown is at the standard working pressure for the ejector.
In the diagram, Pmax denotes the maximum vacuum pressure, and Qmax denotes the maximum suction flow rate. These values are the values listed as the specifications in the manufacturer's catalog and elsewhere.
See below for information on how to change the vacuum pressure.

  1. 1. When the ejector suction port is closed and sealed, the suction flow rate is 0 and the vacuum pressure is at its maximum (Pmax).
  2. 2. As the suction port is gradually opened and air begins to flow (leak), the suction flow rate increases and the vacuum pressure decreases. (State of P1 and Q1)
  3. 3. As the suction port opens further and on to the fully opened state, the suction flow rate reaches its maximum value (Qmax), and the vacuum pressure becomes close to 0 (atmospheric pressure). Thus, as the suction flow rate changes, so too does the vacuum pressure. In other words, if there is no leak in the vacuum port, the vacuum pressure will be at its highest level. As the leakage amount increases, the vacuum pressure decreases and becomes close to 0 when the leakage amount and the maximum suction flow rate become equal. Be aware that when suctioning a workpiece that is breathable or has a leak, the vacuum pressure will not be very high.

Notes

Mounting

  • Be careful not to apply an excessive load or generate moments to the ejector body via the connection port or by mounting.
  • Refer to the manufacturer's catalog for selection and sizing.

Cautions for Handling One-Touch Fittings

One-Touch Fitting Tube Connection and Disconnection

  • Tube attachment
  1. 1. Cut the tube at a right-angle. The tube must not have any cuts on its periphery. Use tube cutters TK-1, 2 and 3 when cutting tubes. Do not use pliers, wire cutters, scissors, etc. This could result in an uneven cut or cause the tube to become flattened. This in turn might make connecting the tube difficult or result in air leakage or the tube coming out after being connected. Be sure to leave a little extra length when cutting the tube.
  2. 2. Hold the tube and push it in slowly until completely inserted.
  3. 3. After inserting the tube, pull it lightly to make sure it does not become detached. Failure to make sure the tube is fully inserted may cause air to leak or the tube to come out.
  • Tube removal
  1. 1. Push-in the release bushing with sufficient force. At the same time, evenly press in the collar.
  2. 2. Keep the release bushing held in so that it does not retract and then pull out the tube. If the release bushing is not being pushed in sufficiently, the tube may become too tightly gripped and make it difficult to pull out.
  3. 3. Detached tubes can be reused by cutting off the section that was previously gripped. Reusing the tube without cutting off the gripped section may lead to air leakage and make it difficult to remove the tube.
