The current discussion on sustainable energy to achieve not only focus on energy consumption in the production process , but also mainly related to the survival of the next generation of environmental protection and the environment . Limited resources on the planet so we have to rethink this .
All along, textile equipment consistently and systematically implement the purpose of reducing energy consumption per unit of output . Rieter efforts to minimize the environmental pollution, the greatest degree of power, to achieve the most optimal use of raw materials production . And its production facilities have done the greatest degree of energy-saving design, which is reflected not only in a single model , but also to form a complete energy system .
Carding - expanded combing the area to reduce energy consumption
Compared with 1992 , the latest Rieter energy production per kg of sliver carding C70 has been reduced by more than 70%.
2002 launch of the C60 made a breakthrough in the field of energy conservation achievements , the key innovation is to work from the original width of 1500 mm to 1000 mm , while the C60 and C70 are beyond the current , active carding area because C70 is currently on the market all carding greatest. Compared with 1992 , the latest Rieter energy production per kg of sliver carding C70 has been reduced by more than 70%. Its oversized combing the area , to ensure the carding quality, while greatly enhancing the productivity, thereby increasing the energy consumption at the same time is very low , thus reducing the energy consumption per kg of sliver production .
Now working width of 1.5 m and an Indian-made C70 1-meter working width of the carding machine comparison. In the case of sliver at the same level of quality , yield per unit time than Rieter C70 carding carding machine made in India more than doubled , thus reducing energy consumption per kg of sliver of 42% , for an hour yarn Spinners yield up to 800 kg , the annual savings of more than 43,000 Swiss francs.
And the machine - compact design to reduce energy consumption
When the output sliver weight 5ktex, delivery speed of 500 m / min , compared with other models in the autoleveler machine RSB-D45 energy consumption per kg of sliver is reduced by 10%.
In industrial production, the machines installed power ( the sum of all motor power on the machine ) is often wrongly associated with the energy efficiency together with the actual size of the installed power consumption irrelevant. Plays a key role in the energy- efficient power the machine , and the effective use of this running time , all parts of the load, and bear the load of the machine efficiency and other factors , must multimeter test data , and the rational calculation of the factory, eventually get the actual energy consumption.
When different drawframes contrast , the most critical is to compare under the same conditions, these conditions include production speed and other process models and so on. When the output sliver weight 5ktex, delivery speed of 500 m / min , compared with other models in the autoleveler machine RSB-D45 energy consumption per kg of sliver is reduced by 10%. Delivery speed of 850 m / min , the production cost per kilogram of yarn , the energy consumption of the process RSB-D45 and only 0.022 kwh . Generally, the drive means more simple, less energy consumption in operation . Since the use of gear reasonable , although a small number of the motor but RSB-D45 is still using fewer driving means such as tension belts and aprons , thus reducing the energy consumption of the machine.
Comber - strengthen cost management to reduce energy consumption
Since 1988 , continues to introduce new Rieter combers combing process makes the total energy consumption reduced by 48%.
Rely on C · A · P · D ( CAPP ) , operation and functionality of Comber has been further optimized and enhanced. In the past few years, with the continuous improvement of precision equipment , production quality combed also rising, at the same time continue to reduce energy consumption . It is worth mentioning that the output E66 comber sliver 72 kg per hour . Even at such high yields, energy production per kg of sliver is still reduced by 46 %. In the case of maintaining a high yield , the same or better quality combed so excellent energy performance possible. With the help of C · A · P · D under significantly more gentle way to reduce the load of each carding carding element.
Since 1988 , continues to introduce new Rieter combers combing process makes the total energy consumption reduced by 48%. Rieter combers on high-precision gear drive, not only reduces energy consumption , but also reduces the loss of spare parts , so that users can more directly benefit .
Ring spinning frame - to increase production to reduce energy consumption
Under the same spindle speed, Rieter ring spinning save 8 % energy than other brands of equipment . Even in the spindle speed is low, still saving 5%.
In conventional ring spinning mill , the energy costs accounted for 40 % of the entire yarn production costs. So , in the end zone with four- spindle drive spindle , or focus on the use of the dragon belt drive , although the fundamental problem is not a principle , but closely related , and energy consumption . If not professional designers , but also to understand the surround angle between the belt and the spindle , the more is not prone to slipping . From the slip angle Rieter spindles with spindle drive four- speaking, 90 -degree angle is surrounded by the best , and without adding the excessive load on the belt , the belt drive is canceled dragon greatly reduce the energy consumption indicators .
In addition to four spindles belt drive , a number of other important criteria also reduces the energy consumption of the ring spinning machine , such as the use of high-precision spindle , optimize interaction and ring gears and other components . Data from the actual production of the display , under the same spindle speed, Rieter ring spinning save 8 % energy than other brands of equipment . Even in the spindle speed is low, still saving 5%.
Compact spinning machine - vacuum device optimized to reduce energy consumption
Therefore, compared with other compact spinning system , Rieter K45 compact spinning machine highest energy consumption can be reduced by 30% .
Since the launch of its compact spinning machine Rieter further reducing energy consumption per kg of yarn . The first is the use of small diameter wharve on K45 compact spinning machine to optimize the vacuum device , and the aerodynamic performance of the entire spindles and adjusting the drive design drafting system. Compared with the first generation of compact spinning machine , the latest K45 reduce energy consumption by 14 %. In addition, the new models are more energy efficient customer site for testing.
Rieter is the only one using direct drive integrated perforated suction drum agglomeration unit , suction tubes and stacking devices sharing integrated suction pipe suppliers, direct drive drum perforated suction reduces energy consumption , while avoiding the apron of the type commonly used to generate friction stacking device . The use of integrated suction channel can save energy . If you use an ordinary suction device , each ingot is about 6-7 watts power , converted to the 1632 's ring spinning , the whole machine suction device actual power is 10 kilowatts to 11 kilowatts .
The experiment found that the actual power Rieter spinning machine closely K45 increased by only 2 kilowatts than the G35 ring spinning , 1632 long car real power was 12.9 and 10.9 kilowatts , while the use of compact spinning apron stackers machine , the actual power of 21.5 kilowatts , compared with a full Rieter compact spinning machine saves 70% energy consumption.
The reason is simple , compared with the perforated apron lower accuracy , optimized air flow guide element and the perforated suction drums reduce the need for air . Central vacuum device using perforated apron precise location can not be negative to the gathering point , unconstrained flow guide device not only increases air consumption , fluctuations in yarn quality is also great . The flow resistance of the channel should be minimized , i.e. , on the suction passage into the agglomeration unit should minimize corner , K45 compact spinning machine according to this concept is the negative pressure passage design, the flow resistance is very low .
If spinning machine spinning transformation , you need to install additional air flow channel and vacuum blower , thereby undermining the energy balance. Therefore, compared with other compact spinning system , Rieter K45 compact spinning machine highest energy consumption can be reduced by 30% .
Jet spinning machine - Application independent drive to reduce energy consumption
In the same production , J20 space required is less than 35% of other spinning technology , which means savings in air conditioning costs by 35% , greatly reducing the spinning mills annual operating costs.
J20 Jet Li reached yarn spinning machine is the newest member of the device . It uses the optimal design, for example , every single spindle is driven independently , the production process when the yarn breakage occurs, the spinning position will automatically run until the robot to move to the re- born head spindles , thus avoiding unnecessary energy consumption during idle time caused by a single ingot . These energy-saving measures in practice, the effect is significant , in the same production speed , air-jet spinning machine than our competitors' models saving 11%.
If further improve machine speed , even in the actual production of energy-saving up to 14%. In the same production , 35% of the space it needs less than other spinning technology , which means a 35% saving air-conditioning costs and greatly reduce the spinning mills annual operating costs.
Rieter rotor spinning machine continuous improvement in energy efficiency . The earliest models compared with R1, R60 latest energy per kilogram of yarn production has been reduced by 20 %, in particular the last generation models , in particular to optimize the energy consumption significantly . The main reason can be summed up as follows: R60 rotor spinning machine main vacuum suction system with intelligent filter cleaning system for use with ; new spinning yarn is to ensure the best quality in the case of negative pressure is maintained over the low state ; dimension optimal energy-saving motors ; economical inverter cooling system.
