Up to 20% increase in energy efficiency
The hybrid drives are effectively matched to the requirements of the corresponding pipe forming machines and pipe bending machines. Hydraulic units of the new system are equipped with constant pumps and are driven by a powerful servo motor. Almost the entire control of the system takes place via the power or rotation speed of the motor. It is very energy efficient. Generally improves the energy efficiency by 15 to 20 %, since the power is always given in accordance with the consumer.
Quieter, smaller, more precise
Its advantages shows the technology especially in areas where powerful drives are requiredas well as with several hydraulic cylinders of different sizes and at different speeds. This applies especially for pipe bending processes and axial pipe forming machines. The hybrid drives are not only smaller and much quieter in operation. Also the heating in the process is minimized. The hydraulic unit needs up to 20% less volume of oil and the required performance of the external cooler is correspondingly lower.
“Efficient machines need efficient drive”
Unique for hydraulic drives is the new positioning accuracy due to the hybrid system. Since each consumer is supplied with a specific volume of oil positions (depending on the consumer) can be approached in the 1/10 mm range. Via the electrical control, the consumption volumes are preselected or stored and via the rotational speed of the drive motor submitted precise.
Responsible for high precision means is not least the specially designed control system. It provides a synchronization of the desired speed of the consumer in relation to the required volume. To ensure that no excess volume is generated. With the combination of electronics and hydraulics, the new solution of transfluid , thus ensuring improved efficiency and ensures that requirements are met in the best possible terms of drive technology.
