Safety instructions
- A10VSO pump is designed to be used in open circuit.
- The project planning, assembling and commissioning of the axial piston unit must be carried out by qualified personnel.
- Before using the axial plunger unit, please read the corresponding manual completely.
- If necessary, please ask Bosch Rexroth for these handbooks.
- During and shortly after operation, there may be a risk of burning of the axial piston unit (especially the electromagnet). Appropriate safety measures (such as wearing protective clothing) should be taken.
- As per the different working conditions (working pressure, oil temperature) of the axial piston unit, the characteristics may change.
- Work pipeline oil outlet:
· Oil nozzles and fixed threads are designed for maximum specified pressure. Machine or system manufacturers must ensure that the safety factor of connecting components and pipes meets the specified working conditions (pressure, flow, hydraulic oil, temperature).
· Work pipeline nozzles and functional nozzles are only designed for hydraulic pipelines.
- Pressure cut-off and pressure control do not provide overvoltage protection. Separate relief valves are provided in the hydraulic system.
- The data and instructions contained here must be followed.
- The product has not been certified as a department that meets the requirements of DIN EN ISO 13849's general machine safety concept.
- The following tightening torque is used:
· Connector:
Refer to manufacturer's instructions for tightening torque of the joints used.
· Installation bolts: For installation bolts that meet the ISO metric thread standard of DIN 13 and the thread standard of ASME B1.1, we recommend that tightening torque be checked separately according to VDI 2230.
· Thread holes in the axial plunger unit:
The maximum allowable tightening torque MG Max is the maximum value for threaded holes and shall not exceed that value.
· Locking screw:
For the metal locking screw provided with the axial plunger unit, the tightening torque MV is required.
