7.2 Installation conditions
The installation position and location oftheaxial piston unit essentially determine
how itisinstalled and commissioned (such aswhen filling and air bleeding theaxial
piston unit).
▶ Fasten theaxial piston unit sothat theexpected forces and torque can
betransferred without any danger. The machine/system manufacturer
isresponsible for sizing thefasteners.
▶ Observe the permissible radial forces as indicated on page 7 of the
datasheet(Part II) on the drive shaft when transferring output drive with radial
loading. Donot use belt drives; see chapter 7.4.3 "General instructions" on
page38.
▶ Make sure theaxial piston unit isalways filled with hydraulic fluid during
commissioning and operation. Also do this also after relatively long standstill
periods, since theaxial piston unit may drain out through thehydraulic lines.
▶ Install carefully and in accordance with ATEX guidelines to prevent damage to the
bearings, housing, clamp collar and drive shaft.
▶ The case drain fluid in the case interior must be directed to the reservoir via the
highest case drain port. Use aline size that matches theport.
▶ A check valve in the drain line is only permissible on a case-by-case basis upon
request. Please consult your proper contact person atBoschRexroth.
▶ To keep noise values low, use elastic elements toisolate all connecting lines from
all vibration-capable components (e.g. reservoir).
▶ Make sure that the suction, reservoir and return lines lead into the reservoir
below the minimum fluid level in all operating conditions. This will prevent air
from being drawn inand foam from forming.
▶ Make sure that a minimum suction pressure of 0.8bar absolute is present at
portS during operation for all installation positions and installation locations
of the axial piston unit; see Fig. 5. See the data sheet (Part II) for additional
pressure levels.
