SUMMARY:  Variable vane pumps: PV7-1x/16

Add to Cart

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.

Design

Hydraulic pumps of type PV7 are vane pumps with variable displacement.

They basically consist of housing (1), rotor (2), vanes (3), statorring (4), pressure controller (5) and adjustment screw (6).

The circular stator ring (4) is retained by the small reciprocating control piston (10) and the large reciprocating control piston (11). The third supporting point of the ring is height adjustment screw (7).

The driven rotor (2) rotates within stator ring (4). The vanes guided within the rotor are pressed against stator ring (4) by centrifugal force.

 

Adjustment

As pressure builds up in the system, the rear side of the small control piston (10) is always pressurised to system pressure via a channel.

In the displacement position, the rear side of the large control piston(11) is also pressurised to system pressure via a bore in control spool (14). Control piston (11) with the larger area holds stator ring (4) in its eccentric position.

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

Control spool (14) is held by spring (13) in a certain position.

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 plate (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 by the rotation of the rotor (2) and via the suction channel (S), the cells are filled with hydraulic fluid. 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 fluid via the pressure channel (P) into the system.

Down control

If the force FP, resulting from the product pressure x area, exceeds the counterforce FF of the spring, the regulator spool(14) is shifted to the spring (13). Thus, the chamber behind the big actuating piston (11) is connected with the tank and thus unloaded.

The small actuating piston (10) which is continuously pressurized with system pressure, moves the stator ring (4) nearly to the central position. The pump maintains the pressure, the flow declines to zero and the leakages are replaced.

Power loss and heating of the fluid are kept to a minimum.

The characteristic curve qV-p is vertical and moves in parallel when setting different pressure values.

On-stroke control

When the pressure in the system falls below the set zero stroke pressure, spring (13) pushes control spool (14) back to its original position.

The large control piston (11) is again pressurised and shifts stator ring (4) to an eccentric position. The pump starts to displace again.

Pump with customer-specific setting:

When ordering, please indicate the setting data in plain text (e.g. qVmax = 20 l/min; pZero stroke = 70 bar). The pump will be set to the desired values and the operating noise is optimized accordingly.

Without a plain text indication, the flow and the zero stroke pressure are set to the respective maximum values and the operating noise is optimized at these maximum values.

Combination options

All pumps of type PV7 can be combined. Each pump with Eshaft is provided with an output spline.

All combinations of a PV7 + optional rear pump are sealed against each other by means of the shaft seal ring of the rear pump. The seal is direction-related. In the case of more stringent requirements with regard to a reliable separation of media, please consult the technical sales department.

Possible combinations and the material no. of the required combination parts can be found in the following table.

Notes on the engineering of multiple pumps

PV7 pumps can be combined as a standard. Each pump is fitted with a splined, second shaft end. When the PV7 is operated as fixed displacement pump, the fixed displacement pump must be used as rear pump. The general technical data are the same as that of the single pump. 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 include the required seals and screws

Calculation example:

Pump combination: P2V7/25-30... + V7/25-30

Required max. pressure: pn = 160 bar

T1,2 = 90 Nm ≤Toff max

T = T1 + T2 = 180 Nm ≤ Tmax

 

V = Displacement volume in cm3

ηhydr.-mech. = Hydraulic-mechanical efficiency

T = Torque in Nm

Δp = Pressure in bar

 

The pump combination can be operated on the basis of the calculated data

Engineering notes

Comprehensive notes and suggestions can be found in The Hydraulic Trainer, Volume 3, RE 00281, “Planning and design of hydraulic systems“.

When using vane pumps, we recommend that the following notes are observed in particular:

Technical data

All technical data mentioned depend on manufacturing tolerances and are valid under certain boundary conditions. Please note that small tolerances are therefore possible and that different boundary conditions (e.g. viscosity) can also result in changes in the technical data.

Characteristic curves

Characteristic curves for flow and absorbed power. Please take the possible maximum operating data into account when dimensioning the drive motor.

Noise/sound pressure level

The sound pressure level values given on Diagrams/characteristic curves were measured in accordance with DIN 45635 part 26.

This means that only the sound emission of the pump is shown. Ambient influences (such as place of installation, piping, etc.) were eliminated. The values are valid for only one pump.

If, for example, two pumps of the same frame size are operated under the same load conditions, the noise level increases according to the following formula

LΣ = 10 lg (100,1•L1 + 100,1•L2)

LΣ = Total noise level

L1 … Li = Sound pressure level of the individual pump

Example: PV7/16 + PV7/16

p = 120 bar

L1 = 56 dB(A)

L2 = 56 dB(A)

LΣ = 10 log (100,1•56 + 100,1•56)

= 59,01 dB(A)

Caution!

The power unit design and influences at the final place of installation of the pump result in the fact that the sound pressure level is usually 5 to 10 dB(A) higher than the value of the pump alone.

Leakage oil

The external leakage fluid of the pump dissipates a part of the frictional heat. The leakage fluid should be directed with low line resistance directly into the tank. The distance between the leakage line and the suction line must be sufficiently large so that the returning leakage fluid cannot be directly re-aspired. The flow of average, external leakage is shown on Product description. These values must not be used for dimensioning the tanks. The relevant variable for the selection of the tank size is the zero stroke power (see Diagrams/characteristic curves).

Leakage fluid cooler

The values for external leakage fluid given on Technical data are average values that are valid for continuous operation. When the pump goes off stroke, the leakage fluid volume briefly increases due to the pilot fluid of the controller. Reductions in cross-sections, long leakage lines, or also leakage fluid coolers can lead to impermissibly high pressure peaks. Suitable measures, e.g. a check valve in the by-pass must prevent the leakage fluid pressure (pmax = 2 bar) from exceeding the permissible values. Otherwise, the shaft seal ring could be damaged.

Fluid tank

Adapt the useful capacity of the tank to the operating conditions.

Caution!

The permissible fluid temperature must not be exceeded → if required, provide cooler!

Lines and connections

Cut off at an angle of 45°. 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 all pipes and fittings before installing them. Minimum distance to the tank bottom 120 mm Lay the leakage line so that the pump can not drain! Do not pipe a pump without controller! Leakage and return flow fluid must under no circumstances be directly re-aspired!

Filters

Whenever possible, use return flow or pressure filters. (Suction filters only in conjunction with underpressure switch / clogging indicator)

Hydraulic fluid

Please observe our regulations according to data sheet RE 07075. We recommend the use of brand name hydraulic fluids. Different hydraulic fluid types must not be mixed, since this can result in decomposition and a deterioration of the lubricating properties. Observe the manufacturer‘s information! The fluid must be changed at regular intervals according to the operating conditions. In this context, the fluid tank must be cleaned from residues.

Commissioning notes

Bleeding

All vane pumps of type PV7 are self-priming. Before initial commissioning, the pump must be bled in order to protect it against damage. We recommend that the housing be filled via the leakage port for initial commissioning. Observe the filter rating! This increases the operational reliability and prevents wear under unfavourable installation conditions. Should the pump not displace bubble-free oil after approx. 20 s, check the system again. After the operating values have been reached, inspect the pipe connections for leakage and check the operating temperature.

Commissioning

Check that the system has been properly and thoroughly assembled. Observe the direction-of-rotation arrows of the motor and the pump. Let the pump start up under no-load conditions and let it displace fluid at zero pressure for some seconds in order to provide sufficient lubrication. In no case may the pump be operated without fluid!

Important notes

Adjustments, servicing and repairs of the pump may only be carried out by authorised, trained and instructed personnel! Use only genuine spare parts of Bosch Rexroth! The pump may only be operated with the permissible data. The pump may only be operated when in perfect condition! When carrying out any work on the pump (e.g. installation or removal), the system must be de-energised and de-pressurised! Unauthorised conversions or changes to the system, which affect safety and function, are not permitted! Fit protective equipment (e.g. coupling guard)! Do not remove any existing protective guards! Strictly observe generally valid safety regulations and regulations for the prevention of accidents!
