INSTALLATION
DYNASET hydraulic compressor can be placed deliberately ensuring free air intake, sufficient cooling and an
easy access to the unit. Position of a compressor should be horizontal. To protect compressor against overheating,
do not allow the warmed cooling air to be directed by cooling fan back to the compressor block. Compressor’s
location should be chosen as far as possible from any source of dust and heat. Protective cover against weather
and season impacts is recommended.
Intake air should not contain any smoke, toxic or flammable gas/vapor. When necessary, intake pipe can be
fitted (the pipe should be measured properly in order to avoid load loss).
DYNASET hydraulic compressor works installed into an original hydraulic system of any carrier machine.
Additionally, return line must be connected to a hydraulic oil tank directly in the shortest possible way in order
to keep return oil pressure under 5 bar. Generally DYNASET’s T-line is to be connected directly to the return
line of a hydraulic system, when hydraulic fluid flows to the tank only through the return filter and cooler.
Both filtering degree and cooling capacity of a hydraulic system should be sufficient (ref. to PARAMETERS).
Ensure that the oil flow is sufficient to run the unit, i.e. at least the nominal flow must be available.
At the oil flow less that demanded nominal rate, compressor’s delivery will be below the nominal. If the oil
flow is so excessive, that the automatic speed control valve is unable to handle it, the unit could be damaged.
In the latter case the oil flow is to be reduced either by dropping down the rotation speed of hydraulic pump
or using flow limiter valve.
DYNASET priority valve is recommended.
After having been connected to the hydraulic system, DYNASET hydraulic compressor is to be started by directing
the oil flow to the unit’s pressure port by means of control valve - manual or solenoid. Even simple ball valve
or three-way valve can be used.
To ensure DYNASET’s proper operation, the hydraulic pressure must be set to the level, at which at least the
nominal power output is achieved (ref. to PARAMETERS). Lower hydraulic pressure reduces compressed air
pressure. Maximum hydraulic pressure is 250 bar (ref. to PARAMETERS). If the hydraulic system main pressure
is higher, service pressure relief valve must be used.
Ensure also that your machine oil cooling is working properly when DYNASET is in operation.
It is possible to use DYNASET either as a mobile compressor and connect hydraulic power
with quick couplings, or make a fixed installation on a carrier machine.
To put DYNASET compressor into operation only pressure- (P) and return (T) lines of a
hydraulic system are to be connected to the unit’s corresponding hydraulic ports. The
proper connection ensures correct rotation direction of the compressor and, by that, an
appropriate cooling of the compressor block. Rotation in opposite direction is not allowed.
Furthermore, cross-connection of hydraulic hoses damages hydraulic motor’s shaft seal.
