Open circuit control strategies

LoaD sensing oPen

CiRCuit system

The pump receives uid directly rom the reservoir through the inlet line. A screen in the

inlet line protects the pump rom large contaminants. The pump outlet eeds a PVG-32

multi-section, load sensing, directional control valve. The PVG valve directs pump ow tothe cylinder and gear motor. A heat exchanger cools the uid returning rom the valve. A

flter cleans the uid beore it returns to the reservoir.

Flow in the circuit determines the speed o the actuators. The position o the PVG valve

determines the ow demand. A hydraulic pressure signal (LS signal) communicates

demand to the pump control. The pump control monitors the pressure dierential

between pump outlet and the LS signal, and regulates servo pressure to control the

swashplate angle. Swashplate angle determines pump ow.

Actuator load determines system pressure. The pump control monitors system pressure

and will decrease the swashplate angle to reduce ow i system pressure reaches the

PC setting. A system relie valve in the PVG valve acts as a back-up to control systempressure.

I system pressure exceeds the PC setting, the PC control reduces the swashplate angle to

maintain system pressure by reducing ow. The PC control continues to monitor system

pressure and changes swashplate angle to match the output ow with the work unction

pressure requirements.

I the demand or ow exceeds the capacity o the pump, the PC control directs the

pump to maximum displacement. In this condition, actual system pressure depends on

the actuator load.

The Features and options section, page 25, includes control schematic diagrams, setting

ranges, and response / recovery times or each control available.Rp is the time (in

milliseconds) or the pump to reach ull displacement when commanded by the control.

Rcr is the time (in milliseconds) or the pump to reach zero displacement when

commanded by the control. Actual times can vary depending on application conditions.

For additional system protection, install a relie valve in the pump outlet line.

The remote PC control is a two-stage control that allows multiple PC settings. Remote

PC controls are commonly used in applications requiring low and high pressure PC

operation.

P101 966

Closed center circuit with remote PC

The remote PC control uses a pilot line connected to an external hydraulic valve. The

external valve changes pressure in the pilot line, causing the PC control to operate at

a lower pressure. When the pilot line is vented to reservoir, the pump maintains a low

standby pressure o 15 to 20 bar [215 to 300 psi]. When pilot ow is blocked, the pump

maintains pressure at the PC setting. An on-o solenoid valve can be used in the pilot

line to create a low-pressure standby mode. A proportional solenoid valve, coupled with

a microprocessor control, can produce an infnite range o operating pressures.






Size the external valve and plumbing or a pilot ow o 3.8 l/min [1 US gal/min]. For

additional system protection, install a relie valve in the pump outlet line.

The LS control matches system requirements or both pressure and ow in the circuit

regardless o the working pressure. Used with a closed center control valve, the pumpremains in low-pressure standby mode with zero ow until the valve is opened. The LS

setting determines standby pressure.

P101 967

Load sensing circuit

Most load sensing systems use parallel, closed center, control valves with special porting that

allows the highest work unction pressure (LS signal) to eed back to the LS control. mr

prr is the dierence between system pressure and the LS signal pressure. The LS

control monitors margin pressure to read system demand. A drop in margin pressure means

the system needs more ow. A rise in margin pressure tells the LS control to decrease ow.

Integral PC unction

The LS control also perorms as a PC control, decreasing pump ow when system

pressure reaches the PC setting. The pressure compensating unction has priority over

the load sensing unction.

Operating parameters

The table, Ratings, page 20, gives maximum and continuous pressure ratings or each

displacement. Not all displacements within a given rame operate under the same

pressure limits. Defnitions o the operating pressure limits appear below.

s prr is the dierential pressure between the outlet and inlet ports. It is the

dominant operating variable aecting hydraulic unit lie. High system pressure, which

results rom high load, reduces expected lie. System pressure must remain at or below

rated pressure during normal operation to achieve expected lie.

C rk prr is the average, regularly occurring operating pressure.

Operating at or below this pressure should yield satisactory product lie. For all

applications, the load should move below this pressure.

m (pk) rk prr is the highest intermittent pressure allowed.

Maximum machine load should never exceed this pressure.

The table, Ratings, page 20, gives minimum, maximum, and rated speeds or each

displacement. Not all displacements within a given rame operate under the same speed

limits. Defnitions o these speed limits appear below.

Rd pd is the maximum recommended operating speed at ull displacement and

1 bar abs. [0 in Hg vac] inlet pressure. Operating at or below this speed should yield

satisactory product lie.

m pd is the highest recommended operating speed at ull power

conditions. Operating at or beyond maximum speed requires positive inlet pressure

and/or a reduction o pump outlet ow. Reer to Inlet pressure vs. speedcharts or each

displacement.

m pd is the lowest operating speed allowed. Operating below this speed will

not yield satisactory perormance.

Knowing the operating conditions o your application is the best way to ensure proper

pump selection. With accurate duty cycle inormation, your Sauer-Danoss representative

can assist in calculating expected pump lie.

Inlet pressure vs. speedcharts or eachdisplacement show the relationship

between speed, ow, and inlet pressure

or each displacement. Use these charts

to ensure your application operates

within the prescribed range.

The charts defne the area o inlet

pressures and speeds allowed or a

given displacement. Operating at lower

displacements allows greater speed or

lower inlet pressure.

Tech Note

System design parameters

Series 45 pumps may be installed in any position. To optimize inlet conditions, we

recommend installing the pump at an elevation below the minimum reservoir uid

level. Design inlet plumbing to maintain inlet pressure within prescribed limits (see Inletpressure limits, page 11)

Fill the pump housing and inlet line with clean uid during installation. Connect the case

drain line to the uppermost drain port (L1 or L2) to keep the housing ull during operation.

To allow unrestricted ow to the reservoir, use a dedicated drain line. Connect it below

the minimum reservoir uid level and as ar away rom the reservoir outlet as possible.

Use plumbing adequate to maintain case pressure within prescribed limits (see Case

pressure limits, page 11).

To prevent damage to the pump, including premature wear, uid entering the pumpinlet must be ree o contaminants. Series 45 pumps require system fltration capable o

maintaining uid cleanliness at ISO 4406-1999 class 22/18/13 or better.

Sauer-Danoss does not recommend suction line fltration. Suction line fltration can

cause high inlet vacuum, which limits pump operating speed. Instead we recommend

a 125 m (150 mesh) screen in the reservoir covering the pump inlet. This protects the

pump rom coarse particle ingestion.

Return line fltration is the preerred method or open circuit systems. Consider these

actors when selecting a system flter:

Cleanliness specifcations

Contaminant ingression rates

Flow capacity

Desired maintenance interval

Typically, a flter with a beta ratio o10 = 10 is adequate. However, because each system

is unique, only a thorough testing and evaluation program can ully validate the

fltration system. For more inormation, see Sauer-Danoss publication 50L04Design

Guidelines or Hydraulic Fluid Cleanliness.

The reservoir provides clean uid, dissipates heat, and removes entrained air rom the

hydraulic uid. It allows or uid volume changes associated with uid expansion and

cylinder dierential volumes. Minimum reservoir capacity depends on the volume

needed to perorm these unctions. Typically, a capacity o one to three times the pumpow (per minute) is satisactory.

Locate the reservoir outlet (suction line) near the bottom, allowing clearance or settling

oreign particles. Place the reservoir inlet (return lines) below the lowest expected uid

level, as ar away rom the outlet as possible.

Series 45 pumps have tapered roller bearings capable o accepting external radial and

thrust loads. The external radial shat load limits are a unction o the load position,

orientation, and the operating conditions o the pump.

The maximum allowable radial load (Re) is based on the maximum external moment (Me)

and the distance (L) rom the mounting ange to the load. Compute radial loads using

the ormula below. The table, Ratings, page 20, gives maximum external moment (Me)

and thrust load (Tin , Tout) limits or each pump rame size and displacement.

All shat loads aect bearing lie. In applications where external shat loads can not

be avoided, maximize bearing lie by orientating the load between the 150 and 210

positions, as shown. We recommend tapered input shats or clamp-type couplings or

applications with radial shat loads. The table, Ratings, page 20, gives BB10 bearing lie or

Auxiliary mounting pads are available or all radial ported Series 45 pumps. Since the

auxiliary pad operates under case pressure, use an O-ring to seal the auxiliary pump

All mounting pads meet SAE J744 Specifcations.

The combination o auxiliary shat torque and main pump torque must not

Tech Note


Tables in the Features and options section give torque ratings or available input shats.

Ensure that your application respects these limits.

Maximum torque ratings are based on shat strength. Do not exceed them.

Coupling arrangements that are not oil-ooded provide a reduced torque rating. Contact

your Sauer-Danoss representative or proper torque ratings i your application involves

non oil-ooded couplings.

Sauer-Danoss recommends mating splines adhere to ANSI B92.1-Class 5. Sauer-Danoss

external splines are modifed class 5 fllet root side ft. The external major diameter and

circular tooth thickness dimensions are reduced to ensure a good clearance ft with the

mating spline. Tables in each section give ull spline dimensions and data.

The table, Shat data, page 27, gives ull spline dimensions and data.

Ratings

A table in the Design and specications section gives sound levels or each displacement.

Sound level data are collected at various operating speeds and pressures in a semi-

anechoic chamber. Many actors contribute to the overall noise level o any application.

Here is some inormation to help understand the nature o noise in uid power systems,

and some suggestions to help minimize it.

Noise is transmitted in uid power systems in two ways: as uid borne noise, and

structure borne noise.

ld-br (pressure ripple or pulsation) is created as pumping elements

discharge oil into the pump outlet. It is aected by the compressibility o the oil, and

the pumps ability to transition pumping elements rom high to low pressure. Pulsations

travel through the hydraulic lines at the speed o sound (about 1400 m/s [4600 t/sec]

in oil) until there is a change (such as an elbow) in the line. Thus, amplitude varies with

overall line length and position.

srcr-br is transmitted wherever the pump casing connects to the rest

o the system. The way system components respond to excitation depends on their size,

orm, material, and mounting.

System lines and pump mounting can ampliy pump noise. Follow these suggestions to

help minimize noise in your application:

Use exible hoses.

Limit system line length.

I possible, optimize system line position to minimize noise.

I you must use steel plumbing, clamp the lines.

I you add additional support, use rubber mounts.

Test or resonants in the operating range, i possible avoid them.

Tech Note

Design and specifcations

Design Series 45 Frame F pumps have a dual servo piston design with a cradle-type swashplate

set in polymer-coated journal bearings. The bias piston increases swashplate angle. The

servo piston decreases swashplate angle. At equal pressure, the larger diameter servopiston overpowers the bias piston. Nine reciprocating pistons displace uid rom the

pump inlet to the pump outlet as the cylinder block rotates on the pump input shat.

The block spring holds the piston slippers to the swashplate via the slipper retainer. The

cylinder block rides on a bi-metal valve plate optimized or high volumetric efciency

and low noise. Tapered roller bearings support the input shat and a viton lip-seal

protects against shat leaks.

An adjustable one spool (PC only, not shown) or two spool (LS) control senses system

pressure and load pressure (LS controls). The control ports system pressure to the servo

piston to control pump output ow.
