What ways does the Paper Machine save energy?

When seeking to maximize the energy performance of a paper machine drive, it is not enough simply to select the most energy efficient components. Correct dimensioning is critical, and complex interactions between components mean that the system as a whole must be carefully designed. Attention must also be paid to the control software, which plays a key role in availability and can therefore have a major impact on overall energy efficiency.

Toilet paper machine is a kind of paper processing machinery for the production of toilet paper; it is the essential tools of the toilet paper manufacturers. In the society of pursuing energy saving and environmental friendly development, enhancing the energy efficiency of equipment is the best choice for toilet paper machine suppliers and buyers.

A large toilet paper machine drive can consume up to 30 MW of power. With production running continuously for very long periods, even a relatively small incremental improvement in energy effi­ciency can produce considerable savings over the long term. Variable speed drives can produce remarkable increases in energy efficiency in certain applications by adjusting the speed of the motor to match the demands of the process.

Another way to save energy for toilet paper machine is regeneration. In applica­tions with successive acceleration and deceleration cycles, regenerative drives produce electricity during the braking phases and feed it back to the network. If the machine can be liquid cooled, which can dramatically reduce the energy consumed in air condition­ing and cooling electrical rooms. Liquid cooling can decrease energy losses to the air within the electrical room by as much as 98 %. Other advantages of liquid cool­ing include a higher power density and compact drive cabinets, and higher pro­tection class enclosures offer increased options

In order to optimize the energy efficiency of a toilet paper machine drive it is important to look at the system as a whole. This is because efforts to boost the efficiency of a single component in isolation may end up causing increased losses elsewhere.

It is therefore crucial to understand how the type of power supply, VSD switching frequency and output voltage, and the motor design, affect total system effi­ciency. Achieving optimum energy effi­ciency involves much more than simply comparing the catalog values.
