Häufig gestellte Fragen - CRDSNU-25-50-P-A Festo

Wie schließe ich den Pneumatikzylinder CRDSNU-25-50-P-A an?

Schließen Sie die Druckluftleitung an die Anschlüsse im Lager-/Enddeckel an. Verwenden Sie geeignete Schläuche und beachten Sie die Anzugsdrehmomente. Details entnehmen Sie der Anleitung.

Wie stelle ich die Geschwindigkeit des Zylinders ein?

Verwenden Sie Rücklaufdrosselventile (GRLA für doppeltwirkende, GRLZ für einfachwirkende) an den Versorgungsanschlüssen. Schließen Sie die Ventile vollständig, dann eine Umdrehung öffnen, und feineinstellen.

Welche Wartung ist erforderlich?

Der Zylinder ist dank Lebensdauerschmierung wartungsfrei. Regelmäßig die Kolbenstange reinigen und bei Bedarf nachschmieren. Keine aggressiven Reinigungsmittel verwenden.

Wie reinige ich den Zylinder?

Reinigen Sie das Produkt mit einem weichen Tuch. Verwenden Sie keine aggressiven Reinigungsmittel. Entfernen Sie nicht das Schmiermittel von der Kolbenstangenoberfläche.

Was tun, wenn die Kolbenstange unregelmäßig läuft (ruckt)?

Mögliche Ursachen: Schmutz auf der Kolbenstange, fehlende Schmierung, falsche Drosselung oder nicht parallele Führung. Reinigen Sie die Stange, schmieren Sie nach, stellen Sie die Drosselung auf Abluft um oder verwenden Sie einen selbstzentrierenden Kupplungskopf.

Welche Sicherheitshinweise muss ich beachten?

Vor Montage- und Wartungsarbeiten Druckluftversorgung abschalten und gegen Wiedereinschalten sichern. Nur im Originalzustand verwenden und Kennzeichnung beachten.

Kann der Zylinder in jeder Einbaulage verwendet werden?

Ja, die Einbaulage ist beliebig. Achten Sie jedoch auf parallele Montage und vermeiden Sie Verspannungen.

Welches Betriebsmedium ist zulässig?

Zulässig ist Druckluft nach ISO 8573-1:2010 [7:4:4]. Geölter Betrieb ist möglich, dann aber immer erforderlich.

Wie entsorge ich den Zylinder?

Entsorgen Sie Verpackung und Produkt umweltgerecht gemäß den geltenden Vorschriften. Weitere Informationen unter www.festo.com/sp.

Wo finde ich Ersatzteile und Zubehör?

Ersatzteile unter www.festo.com/spareparts, Zubehör im Katalog unter www.festo.com/catalogue.

5 Product overview

5.1 Function

The piston rod moves outwards when the cylinder chamber is pressurised. The advanced piston rod is retracted as follows:

• For double-acting cylinders, by pressurising the other cylinder chamber.
  The cylinder force during advance and return is:
  – different with piston rod at one end.
  – identical with through piston rod.
  The position of the piston can be detected by proximity switches.

5.2 Design

1 Male thread on the piston rod for mounting the payload
2 Male thread on the bearing cap for mounting

3 Supply ports in the bearing/end cap
4 Cross hole for mounting

Fig. 1 Sample illustration CRDSNU

5.3 Mounting

• Handle the cylinder so as to avoid any damage to the cylinder barrel and piston rod.
• Observe the following points:

– parallel mounting when using external guides
- installation without distortion
- Compliance with the permissible loads www.festo.com/catalogue

- Observe tightening torque of lock nuts on the male thread 2.

Tightening torque [Nm] 15 15 40 40 60 80 100 100 550 550 on the bearing cap

Tab. 1 Tightening torques on the bearing cap

- Avoid mechanical alignment inaccuracies between the piston rod and an external guide using one of the following measures:

- absolutely precise alignment (general)

– use of a self-aligning rod coupler FK

– use of a guide unit FEN with compensating coupling

A rigid coupling impairs the service life and function of the cylinder.

5.4 Mounting Accessories

In the case of a large payload, high piston speed or when using quick exhaust valves:

• Use suitable shock absorbers or external stops.
  To prevent the payload from sliding down suddenly in the event of an air supply failure in a horizontal or sloping mounting position:
• Use piloted check valves.

To set the speed:

- Use one-way flow control valves in the following supply ports:

• For single-acting cylinders: GRLZ (supply air)
• For double-acting cylinders: GRLA (exhaust air)

The one-way flow control valves are screwed directly into the supply ports. Use of other accessories with a screw-in depth that is too long will damage the cushioning piston.

For position sensing with proximity sensors:

- Use proximity sensors with mounting kit.

Avoid external influence caused by magnetic or ferritic parts in the vicinity of the proximity sensors (spacing ≥ 10 mm).

6 Installation

6.1 Pneumatic Installation

- Connect tubing to supply ports.

7 Commissioning

7.1 Preparation

- Pressurise the system slowly. A soft start valve is used for gradual start-up pressurisation www.festo.com/catalogue.

With medium or large payloads or at high speeds:

- Use sufficiently large arrester fixtures. The product will tolerate the maximum velocities and payloads without external arrester fixtures

→ www.festo.com/catalogue

7.2 Processing

NOTICE!

Risk of collision due to payloads that project into the setup region of the product.

- Only turn adjusting screws while the product is stationary.

1. First of all, close the one-way flow control valves on both sides completely, then unscrew them one complete turn.

2. Pressurise the cylinder simultaneously at both ends. The piston rod moves slightly to a point of balance.

3. Exhaust the cylinder at one end. The piston rod moves to an end position.

4. Start the test run.

5. If the piston rod strikes hard against the end positions or rebounds, correct the speed using the one-way flow control valve.

8 Maintenance

8.1 Cleaning

NOTICE!

• Do not use aggressive cleaning agents.
• Do not clean the guide elements. Regularly removing the lubricant from the surface of the piston rod reduces the service life.

- Clean the product with a soft cloth.

The cylinder is furthermore maintenance-free owing to the lifetime lubrication.

9 Malfunctions

9.1 Fault clearance

Fault description Cause Remedy

Irregular movement of the piston rod (cylinder jolts).	Lack of lubricant. Apply lubricant	in accordance with wearing parts sheet ➔ www.festo.com/spareparts.
	One-way flow control valves restrict the flow of supply air.	Control the exhaust air flow if possible (not the supply air).
	Piston rod is dirty. – Clean the cylinder. – Provide covering (relubric- ate after thorough clean- ing).
	Insufficient supply air (stick slip)	– Keep the tubing lines short and select suitable cross-sections. – Select correct pressure. – Keep pressure constant.
	Pressure is too low. Connect volume upstream.
	Guide is not parallel to direction of stroke.	Use self-aligning rod coupler as in accessories ➔ www.festo.com/catalogue.
Piston does not travel to end position.	Cylinder barrel is damaged. Replace cylinder.
	Setting screw for end-position cushioning is completely closed.	Loosen setting screw.
	Foreign matter in the cylinder. Filter the compressed air.
	Cylinder travels to an external end stop.	Readjust the end stop.
False triggering during position sensing.	Temperatures too high or too low.	Comply with permissible tem- perature range of the proximity sensors.
	Fault at proximity sensor ➔ Instruction manual for prox- imity sensor
