Pressure booster DPA - Festo

1 Pressure booster DPA2d Internet: to change 2022/03 Pressure booster DPAKey featuresFunctionThe Pressure booster is a twin-piston Pressure intensifier used only for com-pressing the DPA is pressurised with com-pressed air, integrated check valves automatically ensure the Pressure on the secondary side is built up. The out-put Pressure p2 can increase to up to twice the value of the input Pressure p1. The required output Pressure is set using a manually operated Pressure regulator. In the case of Pressure boosters without a Pressure regulator, the output Pressure is always double the input air supply to both drive pistons is controlled by a pneumatic directional control valve that reverses automati-cally when the stroke end position has been Pressure booster starts up auto-matically when the input Pressure is applied and the desired output pres-sure has not yet been the set output Pressure is reached, the Pressure booster stops operating to save energy, but restarts automatically when the output pres-sure drops version of the DPA with proximity sensing provides.

2 There is an option of sensing individual strokes of the drive piston with the help of an external sen-sor and adding -NotePressure boosters are used for the occasional drawing-off of pressurised compressed air. Pressure boosters are not suitable as replacement com-pressors, as wear on the seals and drive piston increases significantly when used continuously without -NoteThe Pressure regulator is supplied with no tension on the regulator spring ( only). After applying the input Pressure , the regulator spring is pretensioned by turning the regulator knob until the desired output Pressure p2 is reached. A Pressure gauge is strongly recommended for monitoring the output Pressure p2.

3 The regulator setting of the DPA-63/100 can be secured against unauthorised adjustment using the regulator lock to the compressed air networkInput Pressure sideThe use of a 3/2-way on/off valve ( , or a comparable type) is recommended in the com-pressed air line to the Pressure boost-er. The 3/2-way on/off valve must not be opened until the input Pressure pin has been built Pressure sideIt is recommended that a 3/2-way on/off valve is connected to the output Pressure side of the Pressure booster to ensure safe exhausting of the output Pressure pout. If a 3/2-way valve is not used, the output Pressure can only be exhausted by completely relaxing the regulator spring (turning the regulator knob all the way to the left).

4 H- -NoteIf the system includes a soft-start valve, it is essential to position a 3/2-way on/off valve between the soft-start valve and the Pressure booster . H- -NoteFor Pressure boosters without pres-sure regulator, the air must be ex-hausted externally via a 3/2-way on/off valve.[1] Pressure booster [2] Pressure gauge[3] Silencer[4] Filter[5] 3/2-way on/off valve on the input Pressure side[6] 3/2-way on/off valve on the output Pressure sideKey features32022/03 Subject to changed Internet: booster DPAKey featuresInstallation with air reservoirAn air reservoir ( CRVZS) should al-ways be used on the output Pressure side to compensate for Pressure fluctu-ations.

5 The air reservoir smooths the pulsation of the Pressure booster . It is sensible to fill the volume of the air reservoir with the input Pressure p1 via a connecting line. The Pressure booster only has to make up the difference between the input and the output Pressure . Filling the air reservoir takes less time. A check valve prevents the air from flowing back out of the arrangement corresponds to the scope of delivery of the Pressure boost-er/air reservoir combination available to order (a page 17).Circuit with 2 on/off valvesThe air reservoir is exhausted via the regulator knob of the Pressure with 3 on/off valvesThe air reservoir is exhausted via the additional on/off valve.
