Installation and Maintenance Manual, Compact CBP
There are two distinct cases:
Case 1:
The motor works in braking mode. Required
charge pressure at the inlet port is according
to diagram below.
Case 2:
The motor works in driving mode only. Required
back pressure at the outlet port corresponds to
0% of value given in diagram below, but may
not be lower than bar (9 psi).
The hydraulic system must be such that the
motor will recieve sufficient charge pressure at
the low-pressure port. This applies to all types
of installations.
Note:
The diagram is valid for 1 bar (15 psi) case pressure. With increasing case pressure the charge
pressure must be increased accordingly. The graph is valid when 8 ports are used. Max casing
pressure is bar (4,5 psi)(for 1% of the operation time evenly divided, pressure peaks of max 5
seconds upto 8 bar (116 psi) is allowed). Max permitted case pressure at stand-still is 8 bar (116
psi).
In hanging load applications, charge
pressure at motors connection must
be according to graph below under
all conditions.
