Set-up

Hydraulic pumps of type PGF are leakage gap-compensated internal gear pumps with constant displacement. They basically comprise of housing (1), bearing cover (1.1), end cover (1.2), internal gear (2), pinion shaft (3), plain bearings (4), axial washers (5) and stop pin (6), as well as the segment filler element (7) consisting of segment (7.1), segment support (7.2) and the seal rolls (7.3).

Suction and displacement procedure

The hydrodynamically supported pinion shaft (3) drives the internally geared internal gear (2) in the displayed direction of rotation. During the rotation, there is a volume increase over an angle of approx. 180° in the suction range. An underpressure results and fluid flows into the chambers. The sickle-shaped segment filler element (7) separates suction and pressure chamber. In the pressure chamber, the teeth of the pinion shaft (3) engage in the space between the teeth of the internal gear (2) again. The liquid is displaced via the pressure channel (P).

Axial compensation

The axial compensation force FA takes effect in the area of the pressure chamber and is generated with the pressure field (8) in the axial washers (5). So the axial longitudinal gaps between the rotating and the fixed parts are extraordinarily small and ensure perfect axial sealing of the pressure chamber.

Radial compensation

The radial compensation force FR acts on segment (7.1) and segment support (7.2). The area ratios and the position of the sheet seals (7.3) between the segment and segment support are designed so that an almost leakage gap-free sealing between internal gear (2), segment filler element (7) and pinion shaft (3) is achieved. Spring elements under the sheet seal (7.3) ensure sufficient contact pressure, also with very low pressures.

Hydrodynamic and hydrostatic mounting

The forces acting on the pinion shaft (3) are accepted by hydrodynamically lubricated radial plain bearings (4); the forces acting on the internal gear (2) by the hydrostatic bearing (9).

Gear tooth system

The gear tooth system is an involute tooth system. Its large meshing length results in little flow and pressure pulsation; these little pulsation rates considerably contribute to the low-noise running.

Materials used

Housings (1), bearing covers (1.1), end covers (1.2) and axial washers (5): Aluminum alloy internal gear (2), pinion shaft (3) and stop pin (6): steel plain bearing (4): Copper-tin with steel back segment (7.1) and segment support (7.2): brass alloy sheet seals (7.3): Plastic

Intended use

Internal gear pumps are intended for the set-up of hydraulic drive systems in machine and plant construction.

Technical data

The plant or machine manufacturer must ensure compliance with the admissible technical data and operating conditions. The pump itself does not contain a device to prevent operation outside the admissible data. Operating the pump outside of the admissible technical data is possible to a certain extent, however, this requires the explicit written approval by Bosch Rexroth. All specified technical performance features are average values and apply with the specified boundary conditions. In case of modifications to the basic conditions (e.g. viscosity), the technical data may change as well. Distribution corresponding to the relevant state-of-the-art is possible.

Hydraulic project planning

Bleeding option for commissioning

For Rexroth internal gear pumps PGF.-2/3X, a manual or switchable bleeding option for the initial commissioning or any re-commissioning after maintenance and repair works is to be provided. The bleeding point has to be put into the pressure line in front of the first valve or check valve. Bleeding may only be effected with a maximum counter pressure of 0.2 bar.

Switchable bleeding

Manually operated bleeding

Suction line

The line cross-sections have to be rated for the designed flows in a manner that an ideal suction speed of 0.6 to 1.2 m/s is achieved on average. The suction speed must not exceed a maximum value of 2 m/s.

The suction cross-sections at the pump itself are designed for the maximum flow and can therefore only be used as reference. In case of continuous operation with speeds lower than the admissible maximum speed, the suction tube diameter is to be dimensioned smaller than the suction port of the pump in accordance with the actual suction speed.

All in all, the suction line is to be designed so that the admissible inlet operating pressure is complied with. Bends and the combination of the suction pipes of several pumps are to be avoided. If a suction filter has to be used, it has to be ensured on the system side that the lowest admissible inlet operating pressure is not exceeded even when the filter is contaminated.

Please ensure air tightness of the transitions and dimensional stability of the suction tube as regards to the external air pressure.

The immersion depth of the suction pipe should be as large as possible (at least 100 mm with lowest liquid level). Dependent on the internal tank pressure, the viscosity of the operating medium and the flow ratios within the tank, no vortex must be formed even during maximum flow. Otherwise, there is the risk that air is sucked in. Return flow and leakage fluid must not be sucked in immediately again.

Dimensions in mm

Pressure line

With pressure lines, sufficient bursting protection of the pipes, hoses and connection elements has to be ensured. The cross-sections should be based on the maximum flow in order to avoid additional excessive load of the pump due to back pressure. Here, you must also consider the pipe losses over the entire pressure line length and other line resistances (e.g. bends, pressure filters).

Pressure limitation

The PGF internal gear pump does not comprise any device for compliance with the maximum operating pressure. Setting and limiting the admissible operating pressure has to be ensured on the system side.

The pressure relief valves necessary for that purpose are to be designed considering the maximum flow and the existing pressure increase speed so that the admissible intermittent operating pressure is not exceeded.

Pressure holding function

In the variable-speed drive, the pump can temporarily also be operated below the specified minimum speed, in the pressure holding function. The holding time and the speed necessary for that purpose results dependent on the operating viscosity and the pressure level. For the design, please contact Bosch Rexroth's technical sales department.

In the deactivated state (speed = 0), a leakage flow flows through the pump back into the tank, dependent on the load pressure. If this is to be prevented, a check valve has to be used.

When using a check valve, please observe the information on bleeding options for the commissioning.

Mechanical project planning

Fastening

The screws must be accessible on the machine side so that the required tightening torque can be applied. The tightening torque of the screws is based on the operating conditions and involved elements of the screw connection and has to be specified by the manufacturer in the power unit, machine or system project planning.

Tank

In the tank construction or the selection of suitable standard tanks, the following requirements are to be observed:

Selection of the largest tank volume possible, dependent on the continuous or average flow, in order to allow for the separation of air bubbles by means of sufficient duration time of the medium in the tank. The air release capacity of the hydraulic fluid used is also of importance. Provision of settling zones for the hydraulic fluid in the tank in order to allow for air release. Provision of guiding plates in order to allowing for the deposit of contamination at the tank bottom outside the pump suction area. Large dimensioning of the tank surfaces dependent on the heat output to be dissipated via the tank walls.

Required power unit functions

Hydraulic power units should at least be equipped with the following features:

Tanks, the internal pressure of which corresponds to the ambient pressure in accordance with the design, have to be equipped with breathing filters for pressure compensation purposes. The hydraulic fluid should only be filled in using filling connections excluding filling with unfiltered fluid. The ingress of contamination or humidity must be avoided. In case of use in highly contaminated environments, the tank must to this end be pre-tensioned by means of air pressure. If cleansing of the external tank side is intended or to be expected during the period of use, tank fittings for pipes, lines, or hoses have to be selected, which ensure safe sealing against external pressurization with water jet.

Place of installation and environmental conditions

With places of installation from a geodetic height of more than 1000 m, the pump is to be arranged in or below the tank or the tank is to be pre-tensioned by means of compressed air in order to comply with the admissible minimum inlet pressure. A short suction line with large cross-section has to be selected, bends should not be used.

When installing the pump more than 10 m below the tank, the reduction of the inlet pressure to the maximum admissible value has to be ensured by means of additional measures.

When operating the pump in salt-containing or corrosive environments or when pressure loading with strongly abrasive substances is possible, it has to be ensured on the system side that the shaft seal ring and the sealing area of the shaft do not make direct contact with the environment.

Drive

Electric motor + pump carrier + coupling + pump

No radial and axial forces on the pump drive shaft admissible! Motor and pump must be exactly aligned! Always use a coupling that is suitable for compensating shaft displacements!

Pump combinations

With pump combinations it has to be ensured that on every stage, the admissible operating data for the relevant pump type are complied with. The combined pumps must all have the same direction of rotation. The pump with the highest torque, variable displacement pumps or pumps with intermittent load should be provided as first stage in the pump combination. The maximum through-drive torque must be checked by the project planner for every application. This is also true for already existing (coded) pump combinations. The total of the torques in a pump combination must not exceed the maximum drive torque.

Joint aspiration is not possible. For reasons of stability, we recommend using the ISO 4-hole mounting flange according to VDMA E4 for combinations consisting of three or more pumps. Before operating pump combinations with different media, please consult Bosch Rexroth. PGF combinations are mounted without combination part and are not sealed towards each other.

Selection

The shaft design of the front pump must be E, J or L. The shaft design of the medium pump must be L. The shaft design of the back pump must be N. If a pump of the next smaller frame size is to be attached, the first pump must have the designation K at the end (e.g. PGF3 + PGF2 ⇒ front pump: PGF3-3X/032RJ07VU2K)

Dimensions

The dimensions of the connections correspond to those of single pumps (see Dimensions). The overall length of the pump combination results from the addition of the dimensions “d” of the single pumps (see Dimensions) With the combination of PGF2 and PGF1, the length of the assembly of PGF2 (dimension d) increases by 4.5 mm. With the combination of PGF3 and PGF2, the length of the assembly of PGF3 (dimension d) increases by 2 mm. With the combination of PGF3 and PGF1, the length of the assembly of PGF3 (dimension d) increases by 12.5 mm.

Maintenance schedule and operational safety

For safe operation and a long life cycle of the pump, a maintenance schedule has to be developed for the power unit, the machine, or the system. The maintenance schedule must ensure that the intended or admissible operating conditions of the pump are complied with over the entire period of use.

In particular, compliance with the following operating parameters has to be ensured:

The required oil cleanliness The operating temperature range The filling level of the operating medium

Furthermore, the pump and the system have to be checked for modifications of the following parameters on a regular basis:

Vibrations Noise Temperature difference pump – fluid in the tank Foam formation in the tank Leak-tightness

Modifications of these parameters indicate wear of components (e.g. drive motor, coupling, pump, etc.). The cause must be identified and remedied immediately.

In order to achieve high operational safety of the pump in the machine or system, we recommend checking the parameters mentioned above continuously and automatically and shutting the system off automatically in case of modifications exceeding the usual fluctuations in the intended operating range.

Plastic components of drive couplings should be replaced regularly, however, after 5 years at the latest. The relevant manufacturer's specifications must be considered and be given priority.

For preventive maintenance of the pump, we recommend having the seals replaced after a maximum operating time of 5 years by an authorized Bosch Rexroth service company.

Accessories

Pump safety block

For limiting the operating pressure and for the pump circulation at zero pressure, we recommend our pump safety blocks type DBA… according to data sheet 25890.

Automatic bleeding during commissioning is, however, not possible via DBA blocks. In this connection, we recommend separate, manual bleeding.
