Function description of Powerpackage with mechanicalspring4 Function description of Powerpackage withmechanical spring
The drive works with a pneumatically operated cylinder with pneumohydraulic power stroke. At the same time, a closed oil cylinder and valve system is driven with compressed air, which is controlled in the same way as a
double-acting pneumatic cylinder.
Compressed air is converted to oil pressure in the intensifier part to generate the necessary press force for the power stroke. In the working part, theoil pressure acts on the working piston.
The compressed air is also used for the fast approach of the working piston
to the working position (fast approach stroke) and for the return to the home
position (return stroke).

Specification for hydraulic oil
The following oils are approved for standard application:
Hydraulic oil HLP32 (according to DIN 51524-2), filtered < 5µm, load
rating > 30 N/mm2



Food grade oil Klüber Summit HySyn FG 32

The following hydraulic oils are approved with limitations for standard application:
Hydraulic oil UCON™ LB-165



Synthetic oil ISOTEX 46



Synthetic oil Envolubric PC 46 NWLThe use of hydraulic oils that have not been approved as standard canlead to an increase of maintenance intervals due to an increased intake
of air.



The use of hydraulic oils that have not been approved as standard can
reduce the lubrication capacity lower than for HLP32 hydraulic oils.
This can lead to a shorter lifetime of seals.

Some sealing materials in case of hydraulic oils not approved as standard tend towards increased swelling and therefore to a reduced lifetime of the seals.

NOTE
Loss of warranty in case of the use of non-approved hydraulic oils!
Due to the negative effects on maintenance intervals, swelling behavior andlifetime of the seals in case of the use of hydraulic oils that have not been
approved as standard, the granted warranty becomes extinct.
è Use hydraulic oils that have bee approved by TOX® PRESSOTECHNIK
as standard.
è Use other hydraulic oils only after the express approval of TOX® PRESSOTECHNIK.
è Do not mix different hydraulic oils. Negative effects such as flocculation
cannot be excluded.

7.1

Design principles
When fastening, note the following:–

Installation dimensions–

Weight, including weight of the accessories–

Press force–

Loads caused by the working process (dynamics and vibrations)

No transverse forces may act on the piston rod.
If necessary, use a linear guide for the working piston: either a ram
plate and guiding columns or a guiding rail with guiding carriage.

In the case of horizontal installation the connection side must face upwards.



Elements requiring servicing maintenance, such as oil filling nipple,
vent hole, high pressure measuring connection, control throttle‚X‘ andoil level indicator should be accessible.



Make sure that the ventilation of the hydraulic system is always possible even when installed.

The space requirement for supply lines must be taken into consideration.



The length of the hose lines, the connection of an oil pressure switch oroil pressure monitor can significantly reduce the power stroke.

TOX_Construction_Installation_Guideline_Powerpackage_line-Q_en

23

Design guidelines

7.1.1

Air consumptionFor the air consumption, the fast and return stroke are calculated withthe available air pressure.

The air requirement in the power stroke is calculated depending on therequired press force.
For example, this depends on when the required oil pressure isreached.



If the intensifier chamber is filled with complete air pressure, the air
consumption can indeed be higher than the requirement that is actuallyneeded and calculated.

In general, the specification for the air requirement includes all filling processes required for a stroke. The information only refers to the specificdrive.
For hoses and valves - in particular for long hoses with large cross sections- which are filled and ventilated together with the drive, their consumption
must also be considered when selecting a compressor.
The following applies here: Short lines from the valve to the drive mean
economical energy.
When using pressure regulators (e.g. for the pneumatic spring), low internal
air consumption cannot be avoided. This is usually in the range of a few
liters per hour. Similarly, there might be air losses in the hose and valve
connections. In order to avoid air losses, e.g. at night, the drive can be depressurized during this time.

24

TOX_Construction_Installation_Guideline_Powerpackage_line-Q_en

Design guidelines

7.1.2

Cycle times
The cycle time is calculated depending on the required press force. The following applies:

The smaller the effective press force, the shorter the cycle time.

An effective press force over 90 % should be avoided.

The switching times of the valves and controls upstream of the drive
must be taken into consideration for the specified cycle times.

Requirement for achieving the calculated times:Air pressure
The required air pressure is the result of the desired effective press
force. To achieve a short cycle time, an air pressure as high as possible is recommended for fast and return stroke. If the maximum press
force of the cylinder is to be reduced, this can be realized with a pressure control ZDK (manual or electric) in the power stroke line.

Cross-section of hose
The line cross sections must at least match the connection sizes provided in order to achieve the calculated cycle time. This applies also to
the regulation valves and maintenance units installed upstream of thedrive.
Reduced line cross sections can considerably reduce the cycle time.

Tube lengths
The length of the hoses should be kept to a minimum, since the air consumption as well as the cycle time are increased with the length.

Compressor performance
The compressor performance should always be sized with sufficient
safety.



Speed setting
The speed can be regulated as required by installing throttle checkvalves in the fast approach stroke and return stroke lines (except for
type RP, T). Furthermore, the speed of the power stroke can be adjusted by mounting a throttle in the power stroke line of the unit. The
drive can thus also be used for special applications, such as pressing inbushes, projecting etc.

Optimization of stroke frequency ZHO
The cycle time specifications correspond in general only to the entire
drive under realistic conditions. If necessary, the cycle time can be further reduced using our optional accessory module ZHO.

Design guidelines

7.2

Performance optimization
The ratio of the speed between the return stroke and the fast approach
stroke must be set in order to ensure optimum performance.
An optimum speed ratio between fast approach stroke and returnstroke.



A balanced power stroke speed.

Adequately sized connection sizes (cross-section of hose, switchingvalves, maintenance unit) that prevent a reduction of the power stroke
speed.
For technical data and installation dimensions see data sheet.
(http://www.tox-pressotechnik.de)

7.3

Avoidance of dynamic oil leakage
The dynamic oil leakage is based on the physical effect of drag flow: thehigher the speed, the thicker the oil film dragged along. In the case of an
unfavorable speed ratio between the fast approach stroke and returnstroke, an oil film could get into the pneumatic chambers of the Powerpackage.
The following applies:

The ratio of the speed between the return stroke and the fast approach
stroke must be set.
–

A balanced power stroke speed.
–26

For setting the speed ratios, also the exhaust air dampers must be
installed on the fast approach stroke connections and the returnstroke connections.
For the attuned power stroke speed an exhaust air damper mustalso be installed in the power stroke venting.



For the throttled power stroke speed, the speed ratios between powerstroke speed and venting of the power stroke must be set.
See Installing the speed reduction for power stroke venting.

The power cross sections to the Powerpackage (hose cross sections,switching valves, maintenance unit) must at least meet the specifications in the type sheet.
For technical data and installation dimensions see the type sheet.

Speed reduction of the power stroke
The speed of the power stroke can be reduced if a control throttle is installed in the supply line for the power stroke.
To prevent a dynamic oil leakage, an additional exhaust throttle must be installed in this case so that the speed ratio can be adjusted.
See Installing speed reduction for power stroke.

Horizontal installation Type K and Z
For horizontal installation type K, Z the following applies:

When the diameter difference between the working part and the intensifier part is large, the weight of the intensifier needs to be supported.



The intensifier may only rest on the support device and must not bescrewed onto the working part.

A horizontal assembly with a standing intensifier facing up or with ahanging intensifier facing down is preferable to a lateral assembly.



It must not be possible to activate the fast approach stroke and thepower stroke when doing so.

Attach drop protection if necessary.

When depressurizing a pressure valve (pneumatic spring), the following applies:

This can be displayed, for example, by connecting a pressure gauge orused via transmission to a pressure switch for generating a switching pulse.
The following applies for the activation of the compressed air supply during
venting:During venting, the return stroke and pressure valve (pneumatic spring)must be impinged with compressed air.



It must not be possible to activate the fast approach stroke and thepower stroke when doing so.

Attach drop protection if necessary.

When depressurizing a pressure valve (pneumatic spring), the following applies:

8.2

When the forward stroke connection and back stroke connection areswitched, the compressed air supply of the pneumatic spring must also
be turned off.

Activation according to dynamic pressure method forPowerpackage
If the working piston meets a counterforce during the fast approach stroke,
it stops and the dynamic pressure acting on the piston surface falls. The
power stroke valve switches and the intensifier piston is impinged with compressed air.
The changeover time is controlled and adjusted with the control throttle X.
The drive is actuated like a double-acting pneumatic cylinder, via an electrical, pneumatic or mechanical 4/2 or 5/2 directional control valve or via a 4/3
or 5/3 directional control valve.
The drive must be switched to initial position before changing over to thefast approach stroke.
