Product description

Thanks to their specific design, type PV7... vane pumps with adjustable displacement boast a low flow pulsation and achieve very high repetition accuracy with low pressure peaks during the down control. The noise optimization achieved by adjusting the height adjustment screw provides for a low operating noise. Hydrodynamically lubricated plain bearings ensure a long life cycle. The axial compensation of the displacer provides optimum volumetric efficiency.

Function, section

Type PV7 hydraulic pumps are vane pumps with variable displacement.

They consist essentially of the housing (1), rotor (2), vanes (3), stator ring (4), pressure controller (5) and flow adjusting screw (6).

The annular stator ring (4) is fixed by the small floating actuating piston (10) and the large floating actuating piston (11). The ring is fixed at a third location by the height adjusting screw (7).

The driven rotor (2) rotates within the stator ring (4). The vanes (3) are guided in the rotor (2) and are pressed against the inner running surface of the stator ring (4) by centrifugal force.

Suction and displacement procedure

The cells required for the transport of the fluid (8) are built by the vanes (3), rotor (2) and stator ring (4) and the control plates (9).

To safeguard the pump function during commissioning, the stator ring (4) is kept by the spring (12) behind the big actuating piston (11) in its eccentric position (displacer position).

The cell volume (8) increases as the rotor (2) rotates and the chambers (8) are filled with hydraulic fluid through the suction channel (S). When reaching the biggest cell volume, the cells (8) are separated from the suction side. If the rotor (2) is rotated further, connection to the pressure side is established, the cells narrow and press the hydraulic fluid via the pressure channel (P) into the system.

Adjustment

Simultaneously to the pressure build-up in the system, the back of the small floating actuating piston (10) is always pressurized with system pressure through a channel.

In the flow position, the back of the large actuating piston (11) is also pressurized with system pressure through a bore in the regulator spool (14). The large actuating piston (11), with the larger surface, holds the stator ring (4) in its eccentric position.

The pump displaces fluid at a pressure that is below the zero stroke pressure set on the pressure controller (5).

The regulator spool (14) is held in a certain position by the spring (13).

Pressure relief

If the force FP produced by pressure x area exceeds the counterforce FF of the spring, the regulator spool (14) is pushed against the spring (13). This connects the space

behind the large floating stroking piston (11) to the tank, relieving pressure.

The small set piston (10), which is always under system pressure, moves the stator ring (4) to virtually the center position. The pump maintains pressure, flow returns to zero, leakages are replaced.

Power loss and fluid heating are minimal.

The characteristic curve qV-p runs vertically and moves parallel to various high pressures that are set.

Pressure recovery

If the pressure in the system drops below the set zero stroke pressure, the spring (13) moves the regulator spool (14) back to its original position.

The large stroking piston (11) is pressurized and moves the stator ring (4) to its eccentric position. The pump continues to displace fluid.

Sample pumps with customer-specific setting:

  • PV7-1X/16-20RE01MC0-16-P50 pZero stroke = 50 bar
  • PV7-1X/16-20RE01MC0-16-Q25 qVmax = 25 l/min
  • PV7-1X/16-20RE01MC0-16-P70Q20 pZero stroke = 70 bar; qVmax = 20 l/min

In customer-specific settings, the pump comes noise-optimized at the desired operating points (pzero stroke/qV max) and is delivered in this condition.

In standard versions, the pump is noise-optimized at maximum operating pressure and the zero stroke pressure is reset to 30 bar in its condition as supplied.

Multiple pumps

All type PV7 pumps are combinable. All pumps with shaft "E" have output drive gearing.

All combinations of PV7 and any downstream pump are sealed off from one another by the shaft seal ring of the downstream pump. The seal depends on direction. For stricter requirements on secure media separation, please consult Technical Sales.

The possible combinations and material numbers for the required combination parts can be taken from the following table.

This lock comes in pumps with controller options in the versions ...3..., ...7... or ...8...

Functional description

Once unlocked (by turning the key to the right), the lock (1) can be removed from the controller (2), making the adjuster accessible. To lock, the cover is placed over the adjuster and pressed down as far as it will go, then the key is turned to the left.

The lock can be retrofitted on a standard pump as follows:

  • Unscrew the nut (3)
  • Insert the washer (4) and screw on the nut (3)
  • Install the lock (1) as described in the functional description

  • Flow control (2)
    • Turning clockwise reduces flow.
      • Turning counterclockwise increases flow.
      • The set flow should not be less than 50 % of the maximum value.
  • Pressure adjuster (3)
    • Turning clockwise increases operating pressure.
      • Turning counterclockwise decreases operating pressure.

Project planning information

When using vane pumps, we recommend carefully observing the notes below. Project planning, installation and commissioning of the vane pumps require skilled persons with training.

Technical data

All characteristics are based on manufacturing tolerances and apply under specific boundary conditions. Please note that this means certain deviations are possible and characteristics may vary when boundary conditions (e.g., viscosity) change.

Characteristic curves for flow and power input

When designing the drive motor, observe the maximum possible application parameters.

Sound pressure level

The sound pressure levels shown starting in chapter Diagrams/characteristic curves were measured in the style of DIN 45635 Sheet 26. This means that only the noise emitted by the pump is shown. Ambient influences (place of installation, piping, etc.) were not included. These levels always refer to only one pump. Each additional comparable pump increases the initial level by 3 dB(A).

Notice

Due to the power unit design and influences at the final place of installation of the pump, the sound pressure level is usually 5 to 10 dB(A) higher than the level from the pump itself.

Leakage

Chapter Technical Data contains the average external leakage of the pumps. Note that these values are only intended to serve as project planning guidelines for determining cooler sizes and line cross-sections. The zero stroke power is the relevant factor for dimensioning the reservoir (see chapter Diagrams/characteristic curves). Cross section narrowing and the use of a leakage cooler can cause unacceptably high pressure peaks in the leakage line.

Leakage cooler

The values for external leakage in chapter Technical Data are averages for continuous operation. When the pump relieves pressure, the leakage flow is increased momentarily by the pilot fluid of the controller. Cross section narrowing, long drain lines and leakage coolers can cause unacceptably high pressure peaks. Appropriate steps, e.g., a check valve in the bypass, should be taken to prevent the leakage pressure (pmax = 2 bar) from exceeding permissible limits. Otherwise there is a risk the shaft seal will be damaged.

Pressure limitation

Depending on the controller version, the PV7 vane pump contains no internal mechanism for limiting potential peaks in 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.

Multiple pumps

PV7 pumps are designed to be combinable. Every pump comes with a geared through-drive.

  • When operating the PV7 as a displacement pump, it should be used as the downstream pump.
  • The same general technical data for single pumps applies.
  • The pump that is subjected to higher loads (pressure x flow) should be the first pump stage.
  • When several pumps are combined, the torques that occur can reach impermissibly high values. The sum of torques must not exceed the permissible values (see table)
  • Combination parts must be listed as separate items on the order.
  • The combination parts come with the necessary seals and screws.

Installation notes

Fluid tank

  • Adapt the useful capacity of the tank to the operating conditions.
  • The permissible fluid temperature may not be exceeded; include a cooler, if necessary.

Lines and connections

  • Cut off at a 45° angle.
  • Remove protective plug from the pump.
  • We recommend the use of seamless precision steel pipes according to DIN 2391 and removable pipe connections.
  • Select the clear width of the pipes according to the ports.
  • Thoroughly clean pipelines and fittings prior to installing.

Proposal for piping layout

Dimensions in mm

  • Minimum 120 mm from the tank bottom.
  • Place the leakage line so the pump cannot run dry.
  • Under no circumstances should the leakage and return fluid be directly suctioned back into the pump.

Filter

If possible, use return flow filters or pressure filters.

(Use suction filters only in combination with a ported vacuum switch/clogging indicator).

Hydraulic fluid

  • Please observe our regulations according to data sheet 90220.
  • We recommend brand name hydraulic fluids.
  • Do not mix different types of hydraulic fluids, since this can result in decomposition and deterioration of lubricity.
  • Hydraulic fluid should be replaced at regular intervals according to the operating conditions. Residue should also be cleaned from the hydraulic fluid reservoir at this time.

Drive

Electric motor + pump carrier + coupling + pump

  • No radial or axial forces permissible on the pump drive shaft.
  • Motor and pump must be exactly aligned.
  • Use a torsionally flexible coupling.

Installation positions

Horizontal position preferred

Commissioning

Commissioning information

Bleeding

  • All type PV7 vane pumps are self-priming.
  • Before the initial commissioning, the pump must be air bled to protect it against damage.
  • For the initial commissioning, we recommend filling the housing via the leakage port. Note the filter rating. This increases the operational safety and prevents wear in case of unfavorable installation conditions.
  • If the pump does not convey bubble-free oil after approx. 20 seconds, check the system again. After the operating level has been reached, check the pipe connections for leak-tightness. Check the operating temperature.

Commissioning

  • Check whether the system is thoroughly and properly installed.
  • Note the arrows indicating the direction of rotation on the motor and the pump.
  • Start up the pump without load and let it pump in a depressurized state for a few seconds to ensure sufficient lubrication.
  • Never operate the pump without hydraulic fluid.

Notices

  • The pump should only be adjusted, maintained and repaired by authorized, trained and instructed staff.
  • Use only original Rexroth spare parts.
  • Only operate the pump within the admissible tolerances.
  • Only operate the pump when in good working order.
  • Before working on the pump (e.g., installation/removal), de-energize and depressurize the system.
  • Unauthorized modifications or changes which impair the safety and function are inadmissible!
  • Apply protective devices (e. g. coupling guard)!
  • Do not remove any protective devices.
  • The generally valid safety and accident prevention regulations must imperatively be complied with!
