Hydrostatic Drive System
1. General
A decanter centrifuge has an associated drive system.
A pump unit powers the hydraulic motor ROTODIFF continuously, dependent on the load of the
machine, torque and differential speed are directly and proportionally regulated.
The hydraulic motor ROTODIFF is directly mounted on the centrifuge bowl system wherein the stator
is mounted on the bowl and the rotor drives the scroll directly. The hydrostatic drive system allows a
positive connection between the scroll and the bowl within the machine rotor and forms a completely
closed kinematic system which can be operated completely independently of the bowl drive.
All other scroll drive systems close their kinematic chain outside of the machine rotor and always rely
on the bowl drive. (With the exception of the 2-gear drive, transmissions if overlay in a symmetrical
arrangement.)
The remarkable properties of the hydrostatic scroll drive can be accomplished because the actual
drive motor (Rotor of the hydraulic motor) is built directly on to the decanter centrifuge scroll and is
fed with energy from a power pack and therefore is absolutely independent of the bowl drive.
2. Structure of the Drive System
2.1. Components
The hydrostatic scroll drive system consists of the following components:
• The slow speed high torque hydraulic scroll drive motor ROTODIFF (R), is a rotating unit,
mounted on the centrifuge bowl
• The Pump Unit (P), mounted stationary close to the centrifuge, near the ROTODIFF (R)
• A control system (P3) either hydrostatic (P3.1) or electronic control (P3.2) / (P3.3) and (E)

2.2.1. General Description of the Hydraulic Scroll Drive Motor ROTODIFF
The ROTODIFF housing is directly bolted to the centrifuge bowl (B1) and the drive shaft (C2) is joined
to the centrifuge scroll like a normal gear box.
While the mechanical transmission works as the actual torque-speed-converter coupled with a stationary machine, the hydrostatic scroll drive system combines both elements in one on the machine
rotor.
The ROTODIFF (R) is a slow speed, high torque hydraulic motor with a constant displacement. The
housing is flanged to the decanter bowl, and the Rotor (R6) drives the decanter scroll (C1). In this
way, the scroll is driven at an adjustable differential speed, independently of the bowl speed. The high
pressure hydraulic oil (red path) is brought from the stationary part (R3), to the rotating part of the
motor (R6), by means of the transfer seal (R2). The unpressurized hydraulic oil (blue path), flows back
to the pump unit over the stationary part (R3).

2.2.2. Working Principal of the Hydraulic Scroll Drive Motor ROTODIFF
The hydraulic motor is a positive displacement radial piston motor. The stator/cam (R4) transmits the
force exerted by the piston rollers (R8) through pressure from the pistons (R7). The tangential component of this force produces the rotation of the rotor (R6). The pistons in the cylinders are subject to
fluid under pressure via the distributor (R5) which is mechanically linked to the cam. The pistons are
thus alternately connected to the high pressure of the hydraulic feed system (working stroke; red path)
and the low pressure of the casing (return stroke; blue path).

2.2.3. Working Principle of the Transfer Seal
The transfer seal is critical for the function of the hydraulic motor. It has to ensure a very low leakage
rate under highest pressures, and must have a adequate passage for the high pressure oil flow as well
as extremely low friction loss. A ball cone (R9) is placed on the rotating part eccentrically, and is connected via a double cone floating eccentric ring (R10) to the stationary, compensation cap (R11). The
rotating ball cone and stationary compensation cap (parts R9 + R11) cause a tumbling motion of the
floating eccentric ring, which continually laps and polishes the contacting surfaces. A considerable
axial force is generated between the stationary and the rotating part. This axial force is contained by
the two angular ball bearings (R12).

2.3. The Pump Unit
An electric motor (P1) drives a hydrostatic pump, not visible, immersed in the tank (P2). The oil
supplied by the pump flows over the control block (P3) with integrated high pressure filter to the
scroll drive (R). The return oil flows over the cooler (P4) back to the tank (P2). The control block (P3)
regulates the oil flow to the scroll drive (R) and varies the differential speed in accordance with the
operating conditions and the preset control characteristics.
Choose between three control systems depending on the requirement
• Hydrostatically regulated, automatic control (P3.1)
• Electronically regulated, automatic control with proportional throttle valve (P3.2) and electronic
unit CVC (E1) or MAI (E2).
• Electronically regulated, automatic control with frequency converter (P3.3) and electronic unit
CVC (E1) or MAI (E2).

2.4. Automatic Operation and Regulation
2.4.1. General
The hydraulic system pressure serves as a direct and accurate control variable. The hydraulic system
pressure which is proportional to the scroll torque can be taken as a direct control signal and together
with a suitable control system allows to achieve a very high degree of operational dependability and
reliability of the drive.
There are two basic regulation models, digital and analog:
The digital regulation permits a hand adjustable, fixed differential speed, which will „boost” the differential speed to the maximum at some variable preset pressure (scroll torque).
The analog regulation permits a setting of an adjustable differential speed (so-called base differential
speed ∆n), and a gradual increase in differential speed as pressure (scroll torque) increases. The point
at which the differential speed starts increasing, called the regulation point p1 is variable, and the rate
of increase α is also adjustable.
With both analog and digital regulation, safety cut-outs are provided in the case of high torque p2 and
very high torque p3. These are signalled by pressure switches (adjustable) and are set-up to cut out
the feed pump at p2 and cut-off the bowl drive at p3.
A pressure relief valve protects the system from overload, preventing damage to the scroll drive by
over-torque. This is at a higher value than p3, and has the effect of maintaining maximum torque on
the scroll so that, as the bowl runs down in speed, the falling „G” forces will allow the scroll to commence rotation again and „unplug” a blocked machine.
Note:
Some incompressible products do not respond well to analog regulation, since an increase in differential causes an increase in scroll torque, rather than a decrease. In these cases it is advisable to
use digital operation, and the analog regulation can in most cases be set to operate in a digital mode,
when α = 0 °, and p1 is set at a high value.
There are separation processes where a continuous regulation of the differential speed is redundant or
even undesirable. In such cases the differential speed is adjusted manually, and the measurable system pressure indicating the scroll torque in the centrifuge is only used as an emergency function:
• Quick differential speed increase (digital mode)
• Cut off the feed pump
• Cut off the bowl drive
The whole system is therefore limited to control functions.
But if the differential speed has to be regulated continuously, the most common reference variable
of the system is the scroll torque (hydrostatically measurable system pressure), because it is closely
related to the product load in the centrifuge, and thus allows achieving constant and optimal separation results, within the process related boundaries.

2.4.2. Hydrostatic Regulation Systems
Pump Units Type C
The hydrostatically regulated control block (P3.1) uses the direct feedback of the system pressure
respectively scroll torque as a control variable. The automatic regulation characteristics are adjustable through three hydrostatic valves, the emergency functions are set on a manometer pressure
switch. In addition oil temperature and oil level are monitored on the pump unit.
Such systems are advantageous for their easy operation and reliability.

2.4.3. Electronic Regulation Systems
Depending on the type of electronic unit used the following operation parameters can be displayed
or displayed and controlled. It is also possible to process the measured operation parameters with
an interface unit and control the transmitted data with a PLC controller therefore an easy integration
through norm fieldbus interfaces into a larger process control system is possible.
Operation parameters as follows:
• Bowl speed in rpm (with speed sensor)
• Differential speed in rpm (with speed sensor)
• Hydraulic pressure in bar (over a pressure sensor)
• Additional measured values (oil temperature, vibration, …)
• Operating hours of ROTODIFF, maintenance interval indicator
The benefits of having an electronic control system are manifold:
• Precise control even in the lowest speed range
• Through feedback of the measured differential speed an operation within extremely low differential speed is possible (monitoring of the differential speed through a closed loop control circuit).
• Operating hours of the ROTODIFF, maintenance interval indicator- integration into larger electronic systems
• Utilization of additional regulation parameters is possible (vibration, feed rate, flocculation and
so on)
• Integration capability into a superior system
There are two different electronic regulation systems available: B/C with control block (P3.2) and VFD
with control block (P3.3).

system pressure (torque value) to the electronic display, control, or interface unit (E). A proportional
valve mounted at the pump unit control block (P3.2) controls the oil flow to the scroll drive ROTODIFF (R).
The control current on the proportional throttle valve corresponds directly to the oil flow which is sent
to the scroll drive motor (R).
Mounted on the ROTODIFF (R) are bowl- and scroll speed sensors, the measured signals are also
transmitted to the electronic unit (E). In addition, the oil temperature and oil levels are recorded at the
pump unit.

Pump Units Type VFD
Mounted on the control block (P3.3) is an electronic pressure sensor which transmits the measured
system pressure (torque value) to the electronic display, control, or interface unit (E).
The VFD Drive System consists of a pump unit with a constant displacement pump. The required variation of the oil flow and the resulting differential speed variation is achieved by changing the pumps
rotational speed. This is done by a variation of electric motor speed with a frequency converter (VFD).
Because the differential speed is proportional to the oil flow, an automatic regulation of the scroll
speed is easily obtained.
The scroll torque is sensed hydraulically by the system pressure which is proportional to the scroll
torque. Therefore the differential speed can be exactly monitored and automatically controlled with
precise accuracy, analogue to the scroll torque and solids loading of the centrifuge. Alternatively the
differential speed control signal can be directly taken from the power monitoring of the frequency converter.
Mounted on the ROTODIFF (R) are bowl- and scroll speed sensors, the measured signals are also
transmitted to the electronic unit (E). In addition, the oil temperature and oil levels are recorded at the
pump unit.

3. Benefits of the Viscotherm Hydrostatic Drive System
3.1. Quality and Reliability
Decanter centrifuges are often placed in harsh environments, humidity, heat, dust, and so on. In such
an environment, the hydrostatic drive system is particularly suitable because of the robust design and
resilience.
Hydraulics are also used in industrial, military and transport applications where there is no room for
error – the use differs widely from the most sterile to the dirtiest environments. Examples include airplanes, railways, ships, submarines, elevators, construction equipment, mining, drilling and more
• The hydrostatic drive system is especially suited to operate in such conditions because of the
robust and simple construction; due to this it offers high operational safety
• Stable and reliable operation under fluctuating loading conditions this is one more reason the
market place has justified the hydrostatic drive system
• Long Service life / Quality robust design and automatic heat dissipation
• No overheating of the hydraulic drive motor ROTODIFF, automatic continuous heat dissipation
through the oil-conditioning system
• Hydraulic motors with only few slow moving parts are easy to maintain, in comparison to multiple stage gear-boxes with gears operating at higher speed
• Minimal operating and maintenance costs
3.2. Excellent Weight/Torque Ratio
The entire hydraulic drives made by Viscotherm (ROTODIFF product series) have an outstanding
weight / torque ratio which is given due to the hydrostatic design.
• On average, hydrostatic drives have about half the weight of a standard gearbox with the
same rated torque capacity
• This means that higher bowl speeds can be achieved
• Reduced overhung loading and a reduced moment of inertia considerably decrease the vibrations on the machine
• The excellent torque to weight ratio lead to an increased life time of the main bearings
3.3. Overload Protection
A torque overload or torque peaks do not cause any damage to a Viscotherm drive.
• All mechanical components are protected against overload by various safeguards and finally
protected by a simple pressure relief valve
05/2012

3.4. Behavior of the Drives During Particular Operations
The Viscotherm drive system is a closed kinematic drive chain, i.e. the conveyor drive is operated
independently of the bowl drive system. Due to this fact, the conveyor drive system has full 100%
torque capacity in each operating mode.
• When the bowl is stationary
Clean out of plugged scroll at stand still possible / change of direction of rotation possible.
• While the bowl is running up to speed
• During run-down of the centrifuge
• Ideal cleaning (CIP) at reduced bowl speed (lower G-Force)
• During power failure, the energy from the rotating bowl can be recovered and used for continued operation of the scroll speed and a controlled shut-down, it prevents plugging and costly
maintenance
High differential speed and full torque capacity at the same time. The danger of plugging (and therefore a total disassembly of the centrifuge) is almost eliminated. Flushing is also assisted, since a high
differential speed can be obtained at near-zero bowl speed.
3.5. Automatic Operation and Regulation
On gear-box drive systems complicated control measurements are necessary for the differential
speed control. Bowl speed, pinion shaft speed, gear-box ratio and the electric motor current are factors for control errors.
The hydraulic system pressure serves as a direct and accurate control variable.
• The hydraulic system pressure which is proportional to the scroll torque can be taken as a
direct control signal and together with a suitable control system allows to achieve a very high
degree of operational dependability and reliability of the drive
• Control and monitoring of the operation with easy integration into a process controller through
standardized fieldbus interface
3.6. Highest Energy Efficiency and Increased Through-Put Capacity
The hydraulic technology operates independently of the main drive
• The scroll drive uses only the energy required to drive the scroll; it does not waste energy from
the main drive. No braking action like on electrical back-drive systems, no energy conversion
losses
• The direct precise speed control together with the highest torque capability permit increased
through-put capacities
3.7. Reduction or Elimination of „Chatter or Slip-Stick”(Product Related Oscillations)
Some products, when sedimented in a centrifuge, have a tendency to cause torque peaks, torque
oscillations “Chatter or Slip-Stick” (mostly by plasticizing). For example certain Starches, Cellulose
derivatives, some crystalline products, P.V.C, Polysaccharides, Co-angulated blood, sulphur flower, or
also less frequently caseins etc.. Such oscillations have devastating effects on a rigid drive systems
(gear boxes) and lead to a short lifetime.
• The hydrostatic drives superb damping characteristics that can be further increased by changing the hydraulic impedance of the system
05/2012
• If necessary, with the installation of a suitable hydraulic accumulator system, the damping
effect can be enhanced (tuned), this guarantees the life of the drive system.
14
3.8. Explosion Proof (ATEX) – ATEX Certification-ZONE 1
Applications in various hazardous areas such as oil production and refining will continue to be a challenge to the decanter manufacturer, especially as the centrifuge operation moves into less hospitable
zones.
• The very durable and easy to use Viscotherm drive system is particularly suitable in hazardous
areas because it contains a minimum of electrical components, which are easily obtainable in
ex-proof version; this is in contrast to electric back drives.
• The advantage of explosion proof design (including ATEX certification) will be a key feature to
any decanter manufacturing company, contractor or end-user.
