Description of a Homogenising Tool

Inserting the Homogenizing Tool

| The generators have sharp edges. Handle with care. Risk of injuries!
---|---

The homogenizing tool comes always assembled. The connecting adapter (drive pin (11)) is located on the top of the Shaft and is used to attach the Shaft to the drive motor. When inserting the homogenising tool, make sure that the coupling fits well. This can be easily detected by the “click” that is heard when the coupling Shaft has reached the end of the coupling slot of the motor. Securely fasten the holding screw (6).

Never run homogenising tools dry as the bearings and gaskets will be damaged if the generator is not cooled by the medium. The distance between the homogenising tool and the vessel bottom should not be less than 10mm. The filling of the medium may not be less than about 55 mm. To avoid a vortex it is necessary to insert the dispersing shaft out of the centre of the vessel. If these conditions are met the unit is ready for operation.

Exchanging the Generator

To exchange the Generator (rotor and stator), always take the Shaft out of the motor drive unit as described under 4.6.
For undoing the rotor, use the two special keys (to be ordered separately). The socket wrench is used to counter-hold the Shaft, and the rotor wrench to undo the rotor.
To exchange the stator, remember that the fastening thread is counter- clockwise.
You will find further detailed descriptions in the instruction manual which comes with each homogenising tool.

Always unscrew the rotor first before unscrewing the stator.

Limits on continuous operation of the X 1000 drive unit

In combination with the shafts T6, T10, T17 and T/G20 the X 1000 drive unit can be used in continuous operation.

Overheating protection for the X 1000 drive unit

The X 1000 drive unit features a safety electronic (temperature-dependent overload protection), which prevent the unit from overheating by enabling a cooling mode as soon as the drive reaches the critical temperature.

In that cooling mode the constant-electronic is deactivated and the drive unit is running at a very low speed. After a cooling time of 60 seconds, the machine is ready for operation. Therefore, switch off and on the device to activate the constant-electronic. Before switching on the device, ensure that the lowest rpm-level is set to prevent the media from splashing out of the container. The speed can then be raised step-by-step

****When the overheating of the drive unit occurs several times in a row, we recommend extending the duration of the cooling-phase significantly to avoid permanent damage to the device.

Whether and in what time the engine may overheat depends on the rated input and the present self-cooling power of the drive unit. The rated input of the system is determined by the following factors:

• Set speed
• Tool size and tool design
• Condition of the medium to be processed (such as: viscosity, temperature, volume, inclusions of air or solids, etc.)

Intensified conditions (e.g. higher ambient temperature, fluid temperature or differing viscosity levels) can shift the time of overheating of the drive unit. Therefore, careful handling of the X 1000 drive unit is fundamental!

Maintenance and Cleaning

Cleaning the Drive Unit UNIDRIVE X 1000/X 1000D

To clean the drive unit use only water with a detergent that contains tensides or use isopropyl alcohol for stubborn soiling.

Cleaning the Homogenising Tool

To avoid clogging of the shaft, clean shaft, generator and in case of G-shaft the sealingparts after each use. This is done by operating it in a solvent which dissolves substance residues and is not harmful to the gasket. This is usually sufficient to clean the Generator.

Chemical sterilization may be also a method. General-purpose disinfectants such as formalin, alcohol, etc. may be used. It is important to remove disinfectant residues with sterilized water.

Make sure that the bearings, O-rings and gaskets are resistant to solvents.

Sterilization with moist heat:

This denotes the use of a steam jet pressurized to 2 bars at 120°C.

Rough Cleaning of Flow-Through-Chamber and Tubing

Flow-through-chamber and tubing might be roughly cleaned by pumping a suitable liquid through the chamber instead of the medium.

Cleaning the Inside of the Flow-Through-Chamber

Before cleaning please disconnect first drive unit from mains and detach the flow through chamber DK 30

The flow-through chamber can be disassembled without disconnecting the tubes. Attention: Rest liquid escapes!!!

Please take care that neither O-rings nor any other parts experience any damage during assembling respectively disassembling the flow-through chamber.

Before operation check the slip ring sealing. The slip ring should be easily turned by hand. If it is stuck after a long period without use just loosen slip ring by wetting it with water. Never operate the flow-through chamber if the slip ring is stuck!!

Always unscrew the rotor before the stator.
Note: Rotor and stator wrenches are listed in the price list under accessories.

Maintenance of drive units UNIDRIVE X 1000/X 1000D

****| Do not open the instrument. Repairs are only to be carried out by trained service technicians.
---|---

Maintenance homogenizing tools

The gaskets in the homogenizing tools must be constantly monitored. In the event of leakage the suction effect of the rotating Shaft can cause the medium to penetrate as far as the drive unit. If liquid emerges from the side hole at the top of the Shaft tube stop work immediately and check the gaskets. The function of the Generators depends on the condition of the sharp edges on the rotor and stator. These edges may be blunted very quickly in abrasive media, reducing the effectiveness of homogenizing.
