Series 90

General Description Series 90 axial piston variable displacement pumps are of cradle swashplate design with variable displacement, and are intended for closed circuit applications.

The flow rate is proportional to the pump input speed and displacement.

The latter is infinitely adjustable between zero and maximum displacement.

Flow direction is reversed by tilting the swashplate to the opposite side of the neutral (zero displacement) position.

General Technical Specifications Speed Range

Case Pressure

The Rated Speed is the highest speed recommended at full power condition at which normal life can be expected.

Under normal operating conditions, the maximum continuous case pressure must not exceed 3 bar (40 psi).

All other operating conditions (e.g. fluid viscosity and temperature, charge pressure) must be within recommended ranges.

Maximum allowable intermittent case pressure during cold start must no exceed 5 bar (75 psi).

Hydraulic Fluids Maximum Speed is the highest operating speed permitted and cannot be exceeded without reduction in the life of the product or risking immediate failure and loss of driveline power (which may create a safety hazard).

Braking Warning !

The loss of hydrostatic driveline power in any mode (e.g. acceleration, deceleration, or neutral mode of operation) may cause a loss of braking capacity. A braking system which is independent of the hydrostatic transmission must, therefore, be provided which is adequate to stop and hold the system should the condition develop.

Maximum Attainable Speed requires approval from SAUER-SUNDSTRAND Application Engineering. Special unit hardware and/or special operating conditions may be required.

System Pressure Range System pressure is a dominant operating variable affecting hydraulic unit life. High pressure, which results from high load, reduces expected life in a manner similar to many mechanical assemblies such as engines and gearboxes.

The maximum pressure is the highest intermittent pressure allowed. It is determined by the max. machine load demand.

Ratings and data for Series 90 products are based on operating with premium hydraulic fluids containing oxidation, rust and foam inhibitors.

The following are suitable: - Premium turbine oils - API CD engine oils per SAE J183 - M2C33F or G automatic transmission fluids (ATF) - Dexron II (ATF) meeting Allison C3 or Caterpillar TO-2 - Certain agricultural tractor fluids (STOU) - Hydraulic fluids per DIN 51524, part 2 (HLP) - Hydraulic fluids per DIN 51524, part 3 (HVLP) Fire resistant fluids are also suitable at modified operating conditions. For more information see Sauer-Sundstrand publication BLN-9887 or 697581.

Refer to publication ATI-9101E for information relating to biodegradable fluids.

While fluids containing anti-wear additives are not necessary for the satisfactory performance of the Series 90 units, they are often required for associated equipment. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion and corrosion of the internal components.

It is not permissible to mix hydraulic fluids. Contact SauerSundstrand Application Engineering for more information.

Temperature Limits For petroleum based fluids, see page 10 for maximum allowable temperatures.

These temperature limits apply at the hottest point of the transmission, which is normally the case drain.

Maximum pressure is assumed to occur a small percentage of operating time, usually less than 2 % of the total.

Heat exchangers should be sized to keep the fluid within the limits.

Maximum pressure is normally the pressure relief valve setting. It is desirable to have a machine duty cycle with the percentage of time at various loads and speeds. An appropriate design pressure can be calculated by our application department from this information. This method of selecting operating pressure is recommended whenever duty cycle information is available.

Charge Pressure

12

The charge pressure setting listed in the Model Code is based on the charge flow across the charge pressure relief valve at fluid temperature of 50 °C (120 °F). The motor charge relief valve pressure setting is the pressure generated at a charge flow of 15 l/min (4 gpm).

Options Reservoir

Charge Pressure Filtration - Option R, T, P, L

The function of the reservoir is to remove air and to provide make up fluid for volume changes associated with fluid expansion or contraction, possible cylinder flow, and minor leakage.

The pressure filter can be integrally mounted directly on the pump or mounted remotely, Figure 5, for ease of servicing.

A 200 mesh screen, located in the reservoir or the charge inlet line, is recommended when using charge pressure filtration. This system requires a filter capable of withstanding charge pressure.

The reservoir should be designed to accommodate maximum volume changes during all system operating modes and to promote deaeration of the fluid as it passes through the tank.

A suggested minimum reservoir volume equal to 1/2 charge pump flow/min. This allows 30 seconds fluid dwell for removing entrained air at the maximum return flow. This is usually adequate to allow for a closed reservoir (no breather) in most applications. The reservoir outlet to the charge pump inlet should be above the bottom of the reservoir to take advantage of the gravity separation and prevent large foreign particles from entering the charge inlet line.

Pressure filters with Beta 10 ratio of 10-20 have been shown to provide acceptable performance.

Figure 5: Charge pressure filtration

Screen

Hydraulic fluid reservoir Adjustable Charge pressure relief valve

The reservoir inlet (fluid return) should be positioned so that the flow to the reservoir is discharged below the normal fluid level, and also directed into the interior of the reservoir for maximum dwell and efficient deaeration.

Suction Filtration - Option S The suction filter is placed in the circuit between the reservoir and the inlet to the charge pump, as shown in Figure 4. For closed loop transmissions with controlled reservoir ingression a filter having a Beta 10 ratio of 1.5 to 2 has been shown to provide acceptable performance.

Options (Continued) Multi-function Valve Both the pressure limiter sensing valves and relief valves are built into the multi-function valves located in the pump endcap. The sequenced pressure limiter/high pressure relief valve system in the Series 90 provides an advanced design of overpressure protection.

The pressure limiter avoids system overheating associated with relief valves and the sequenced relief valves are available to limit pressure spikes which exist in severe operating conditions.

Because the relief valves open only during extremely fast pressure spike conditions, heat generation is minimized during the short time that they might be open.

For some applications, such as dual path vehicles, the pressure limiter function may be defeated such that only the relief valve function remains. The relief response is approximately 20 ms whether used with or without the pressure limiter function.

Overpressure Protection The Series 90 pumps are designed with a sequence pressure limiting system and high pressure relief valves (Figure 8). When the preset pressure is reached, the pressure limiter system acts to rapidly destroke the pump so as to limit the system pressure. Typical response is less than 90 ms. For unusually rapid load application, the high pressure relief valve is available to also limit the pressure level. The pressure limiter sensing valve acts as the pilot for the relief valve spool, such that the relief valve is sequenced to operate above the pressure limiter level.

Pressure Limiter Operation Referring to Figure 8 when set pressure is exceeded the pressure sensing valve (A) flows oil through passage (B) and across an orifice in the control spool raising pressure on the servo which was at low pressure. Servo pressure relief valves (C) limit servo pressure to appropriate levels.

The pressure limiter action cancels the input command of the displacement control and tends to equalize servo pressure. Swashplate moments assist to change the displacement as required to maintain system pressure at the set point.

In some applications it is desirable to bypass fluid around the variable displacement pump when pump shaft rotation is either not possible or not desired. For example, a “down” vehicle may be moved to a service or repair location or winched on a trailer without operating the prime mover.

Series 90 pumps are available with an optional speed sensor for direct measurement of pump input speed.

Series 90 pumps are designed with a bypass function. The bypass is operated by mechanically rotating the bypass hex on both multi-function valves three (3) turns counterclockwise (CCW). Refer to figures 8 on page 14.

This connects working loop A and B and allows fluid to circulate without rotating the pump and prime mover.

Caution !

Bypass valves are intended for moving a machine or vehicle for very short distances at very slow speeds.

They are NOT intended as “tow” valves.

A special magnetic speed ring is pressed onto the outside diameter of the cylinder block and a Hall effect sensor is located in the pump housing. The sensor accepts supply voltage and outputs a digital pulse signal in response to the speed of the ring. The output changes its high/low state as the north and south poles of the permanently magnetized speed ring pass by the face of the sensor. The digital signal is generated at frequencies suitable for microprocessor based controls.

This sensor will operate with a supply voltage of 4.5 to 15 VDC, and requires a current of 12 mA at 5.0 VDC under no load. Maximum operating current is 30 mA at 1 kHz. Maximum operating frequency is 15 kHz. Output voltage in “High State” (VOH) is sensor supply voltage minus 0.5 VDC, minimum. Output voltage in “Low State” (VOL) is 0.5 VDC, maximum.

The sensor is available with a Packard Weather-Pack 3 or 4-pin sealed connector or a Turck Eurofast M12x1 4-pin connector.

Options (Continued) Charge Pump Charge flow is required on all Series 90 pumps applied in closed circuit installations to make up internal leakage, maintain a positive pressure in the main circuit, provide flow for cooling, filtration, replace any leakage losses from external valving or auxiliary systems and provide flow and pressure for the control system.

Rated charge pressure must be maintained at its specified pressure under all conditions of operation to prevent damage to the transmission.

Many factors influence the charge flow requirements and the resulting charge pump size selection. These factors include system pressure, pump speed, pump swashplate angle, type of fluid, temperature, size of heat exchanger, length and size of hydraulic lines, control response characteristics, auxiliary flow requirements, hydrostatic motor type, etc. When initially sizing and selecting hydrostatic units for an application, it is frequently not possible to have all the information necessary to accurately evaluate all aspects of charge pump size selection.

The following procedure will assist the designer in arriving at an initial charge pump size selection for a typical application, it is emphasized that unusual application conditions may require a more detailed review of charge pump sizing.

Testing is recommended to verify that adequate charge pressure is maintained under actual operating conditions.

Charge Pump Sizing / Selection The first step in approximating the proper size charge pump is to determine the charge flow requirements for the total system under different modes of operation.

The total charge flow requirements must include the flow requirements of the pump/ motor(s) and all auxiliary components which remove fluid from the system.

The charge pump sizing must consider the pump and motor(s) operating at their maximum operating pressure and also when the pump is operating at minimum speed.

A) Charge Flow Requirement - Pump Determine the pump speed, minimum and operating, and maximum system pressure at these speeds. If the pump speed is less than 1 000 min -1, use the data published for 1 000 min-1 .

Referring to the figure 12 on page 17, “Charge Flow Requirement - Pump,” determine the flow factor Fp at the desired flow requirement for the pump:

Fp x Frame Size x 3.785 = l/min, Charge Flow Requested - Pump 75 Fp x Frame Size Qp = = gpm, Charge Flow Requested - Pump 75 Qp =

Frame Size in (cm3/rev)

16

B) Charge Flow Requirements - Motor Determine the motor speeds and maximum system pressure. Referring to the accompanying figure 13, “Charge Flow Requirement - Motor”, determine the flow factor of the motor Fm. Using the following equation, determine charge flow requirements for the motor Qm. Qm = Fm x Frame Size x 3.785 = l/min, Charge Flow Requested - Motor 75 Fm x Frame Size Qm = = gpm, Charge Flow Requested - Motor 75 C) Total Charge Flow Requirements The total charge flow requirements Qt is the sum of the flow requirements of each of the components in system; namely: Qt= Qp + Qm1 + Qm2 + Qaux = l/min, (Tot. Charge Flow Req.) D) Determine Required Charge Pump Size ● Referring to the accompanying figure 14, “Charge Pump Flow”, select the correct charge pump requirements determined above and the pump input speed. ● Refer to the “Charge Pump Size/ Availability and Speed Limits” chart to verify that the maximum speed limit of the selected charge pump is not be exceeded. ● If the desired size noted in the chart is not available, always select the next size larger charge pump. ● If the standard size charge pumps are not adequate to meet the flow requirements of the system, a Gear Pump can be mounted to the auxiliary mounting pad to provide the necessary additional flow.

System features and conditions which may invalidate the above calculations include (but not limited to): ● continuous operation at low input speeds (< 1 500 min-1 ) ● high shock loadings ● excessively long system lines (> 3 m [9.8 ft]) ● auxiliary flow requirements ● use of high torque low speed motors If any of the above conditions exist, contact SAUERSUNDSTRAND Application Engineering.

Maximum Allowable Radial Side Load, Re = Me / L All external shaft loads will have an effect on bearing life. In applications where external shaft loads can not be avoided, the impact on bearing life may be minimized by orientating the load to the 90 or 270 degree position.

Please contact Sauer-Sundstrand Application Engineering for an evaluation of unit bearing life if:

Series 90 pumps are designed with bearings that can accept external radial and thrust loads. The external radial shaft load limits are a function of the load position and orientation, and the operating conditions of the unit.

The maximum allowable radial side load (Re), based on the maximum external moment (Me) and the distance (L) from the mounting flange to the load, may be determined from the table and diagram below. Thrust (axial) load limits are also shown.

•

continuously applied external loads exceed 25 % of the maximum allowable radial side load, Re.

•

the pump swashplate is positioned on one side of center all or most of the time.

•

the unit bearing life (B10) is critical.

Tapered input shafts or “clamp-type” couplings are recommended for applications where radial shaft side loads are present.

The time required for the pump output flow to change from zero to full flow (acceleration) or full flow to zero (deceleration) is a function of the size of the orifice in the control flow passage.

Input Shaft Rotation

A range of orifice sizes is available for the Series 90 Electric Displacement Control to assist in matching the rate of swashplate response to the acceleration and deceleration requirements of the application. Testing should be carried out to determine the proper orifice selection for the desired response.

Controls - Circuit Diagram, Nomenclature and Description (Continued) Electric Displacement Control (EDC), Options KA, KP The electric displacement control uses an electrohydraulic Pressure Control Pilot valve to control the pilot pressure.

The Pressure Control Pilot valve converts an electrical input signal to a hydraulic input signal to operate a 4-way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servo piston tilts the cradle swashplate, thus varying the pump´s displacement from full displacement in one direction to full displacement in the opposite direction. The control has a mechanical feedback mechanism which moves the servo valve in relation to the input signal and the angular position of the swashplate. The electrical displacement control is designed so the angular rotation of the swashplate (pump displacement) is proportional to the electrical input signal.

Due to normal operating force changes, the swashplate tends to drift from the position preset by the machine operator. Drift, sensed by feedback linkage system connecting the swashplate to the control valve, will activate the valve and supply pressure to the servo piston, maintaining the swashplate in its preset position.

Features and Benefits of the Electric Control: • The electric displacement control is a high gain control: With only a small change of the input current, the servo valve moves to a full open position thus porting maximum flow to the servo cylinder.

• Oil filled pilot valve case lengthens control life by preventing moisture ingression and dampening component vibrations.

Figure 26: Cross-section of electric displacement control valve

• All electrical displacement controls are equipped with dual coil pilot valves. The user has the option of using a single coil or both coils (in series or parallel).

• Internal mechanical stops on the servo valve allow rapid changes in input signal voltages without damaging the control mechanism.

• Precision parts provide repeatable accurate displacement settings with a given input signal.

• The swashplate is coupled to a mechanism. The control valve hydraulically connects the ends of the servo piston to drain when an electric input signal is not present.

• These features result in: - Simple, low cost design.

- Pump will return to neutral after prime mover shuts down.

- Pump returns to neutral if external electrical input signal fails or if there is a loss of charge pressure.

Response Time The time required for the pump output flow to change from zero to full flow (acceleration) or full flow to zero (deceleration) is a function of the size of the orifice in the control flow passage.

A range of orifice sizes is available for the Series 90 Electric Displacement Control to assist in matching the rate of swashplate response to the acceleration and deceleration requirements of the application. Testing should be carried out to determine the proper orifice selection for the desired response.

Typical response times between neutral and full flow at the following conditions: ∆p = 210 bar (3 000 psi) Temperature = 50 °C (122 °F) Charge Pressure = 24 bar (340 psi) Table 14: Typical response times

Manual Displacement Control (MDC), Options MA, MB The manual displacement control device converts a mechanical input signal to a hydraulic signal that tilts the cradle swashplate through an angular rotation varying the pump`s displacement from full displacement in one direction to full displacement in the opposite direction.

The manual displacement control has a mechanical feedback mechanism which moves a servo valve in the proper relationship to the input signal and the angular position of the swashplate.

The manual displacement control is designed so that the angular rotation of the swashplate is proportional to the mechanical input signal. The control is designed with an internal override mechanism which allows the mechanical input to be moved at a faster rate than the movement of the swashplate without damage to the control.

Features and Benefits of the Manual Control: • Precision parts provide repeatable, accurate displacement settings with a given input signal.

• The manual displacement control is a high gain control: With only small movement of the control handle (input signal), the servo valve moves to full open position porting max. flow to the servo cylinder. This is a high response system with low input force.

• The integral override mechanism allows rapid changes in input signal without damaging the control mechanism.

• Precision parts provide repeatable, accurate displacement settings with a given input signal.

• A double-acting servo piston is coupled to a spring centering mechanism. The servo control valve is spring centered such that with "no input signal" the servo valve is open centered and thus no fluid is ported to the servo cylinder.

• These features result in: - Pump will return to neutral after prime mover shuts down.

- Pump will return to neutral if external control linkage fails at the control handle or if there is a loss of charge pressure.
