Two porting options and a variety of equipmentoptions are available for this motor (see Section 5and 6) to ensure the best possible adaptationto your specific application.

The use of dual pressure crossline relief valves broa-dens the spectrum of possible applications. The lowsetting of the relief valve permits softgentle braking of the motor. When the relief valve istriggered to its high setting, maximum accelerationand braking torque is available at the motor. A typi-cal application of this type is a turning and boringmill drive.

This motor is used primarily in clo-sed loop circuits.

It is at maximum displacement(Vmax) with no control signal.Variable displacement control tolower displacement is accomplishedhydraulically with the application ofa proportional control pressure sig-nal by the operator.

The motor is also equipped witha system pressure override (POR)which increases the motor’s displa-cement in response to system-rela-ted demands for torque whena predefined system pressure set-ting is reached, overriding the ope-rator’s command for lower displace-ment.

Variable motor with pressure override

In addition, this motor has • electric maximum displacement override (DOR)

that makes it possible to shift the motor to itsmaximum displacement independently of thecontrol pressure, and to lock it there, (as withthe fixed displacement motor.

• electric brake pressure shut off (BPS). It preventsabrupt reactions and response by the systempressure override control to dynamic brakingpressures, and thus makes it possible for amore controlled deceleration of the vehicle.

Linde pressure regulated motors are suitable for bothopen and closed loop circuits. They are high-pressurecontrolled, and are at minimum displacement (Vmin)when system pressure is below the pressure regulationset point of regulation begin (RB). When the pressureregulation set point is reached, the motor smoothlyincreases displacement in response to system-depen-dent demands for torque. The additional maximum dis-placement override control makes it possible to shiftthe motor to maximum displacement independently ofthe pressure regulating control, and locks it there aswith a fixed displacement motor.

The maximum displacement override signal can beeither:

• pneumatic shifted with a low pressure air signal • hydraulic shift with a hydraulic pressure signal • electric shift with a direct current electric signal.

The typical configuration of pressure regulated motorsfor use in open or closed loop circuits is as follows:• Open loop circuit: with cross over relief valve pro-

tection and counter balance valve (see Section 6.7)• Closed loop circuit: with electric brake

pressure shut off (see Section 6.6)

6.6 Brake Pressure Shut Off (BPS)Pressure regulated motors shift towards maximum dis-placement if the operating pressures are equalto or above the regulation begin (RB) pressure setting,irrespective of which working port the pressure isgenerated. With propel systems, this can lead tounpleasant effects if, for example, during dynamic bra-king high pressures are generated above the regulationbegin setting, the motor will shift to maximum displa-

cement and an extremely strong braking effect willoccur.

Brake pressure shutoff prevents the braking pressureor deceleration pressure from reaching the regulator.Only the drive pressure or acceleration pressure is feltby the motor’s pressure regulator, and thus the motorwill remain in minimum displacement during braking.

6.5 Crossline Relief ProtectionHMF/HMV/HMR-02 motors are available with integratedcrossline relief valves to protect the system against pres-sure overloads. Relief valves are pilot operated reliefsin combination with anti-cavitation checks. The use ofthese relief valves is recommended whenever pressurelimiting control has not been provided in some other way(e.g. by means of primary pressure relief or pressure cutoff at the pump or LSC valves.

Anti-cavitation is facilitated through connection E, shownin the circuit diagrams. This may be needed in open loopcircuits if the motor requires more oil than can be suppliedto it, especially in dynamic braking situations. For specialinstallations (e.g. for turning and boring mill drive), the useof dual pressure cross over relief valves should be consi-dered. (see Section 2)

6.7 Counter BalanceThe counter balance valve prevents over speedingthe motor during an over running condition. Toachieve this, the motor’s exhaust oil is automaticallymetered to restrict its escape. Different braking beha-viours are possible. With integrated anti-cavitation

circuitry, cavitation can be prevented. In addition, a flushingvalve can be incorporated to allow motor case flushing.Counter balance valves are typically used in drive systems in open loop circuits.

10. PRESSURE FLUIDS AND FILTRATIONPermitted Pressure Fluids

• Mineral oil HLP to DIN 51524• Biodegradeable fluids upon request• Other pressure fluids upon request

Viscosity Recommendations

Working Viscosity Range [mm2/s] = [cSt] 10 to 80

Optimum Working Viscosity [mm2/s] = [cSt] 15 to 30

Max. Viscosity (short time start up) [mm2/s] = [cSt] 1000

The hydraulic components and parts are designed for a temperature range of -20 °C to max. +90 °C.

Working temperature [°C] Viscosity class [mm2/s] = [cSt] at 40 °C

ca. 30 to 40 22

ca. 60 to 80 46 or 68

Linde recommend using only pressure fluids which areconfirmed by the producer as suitable for use in highpressure hydraulic installations. For the correct choiceof suitable pressure fluid it is necessary to know theworking temperature in the hydraulic circuit. The pres-sure fluid chosen must allow the working viscosity tobe within the optimum viscosity range (refer to abovetable).

Filtration

In order to guarantee proper functions and efficiency ofthe hydraulic pumps the purity of the pressure fluidover the entire operating period, must comply to atleast class 18/13 according to ISO 4406. With modernfiltration technology, however, much better values canbe achieved which contributes significantly to exten-ding the life and durability of the hydraulic pumps andcomplete system.

Technical Data

Attention!Due to pressure and speed influences the leakage fluidtemperature is always higher than the circuit tempera-ture. The temperature must not exceed 90 °C in anypart of the system. Under special circumstances, if thestated conditions cannot be observed then pleaseconsult Linde.
