How to realize the energy saving of pneumatic actuators?
Introduction: Reasonable selection of each component of pneumatic device, intelligent combination, can recover the original waste of heat energy, to achieve 30% energy saving target. In this work, the analysis and evaluation of the compressed air system will be of great help to the user.
According to a European Union survey, the adoption of new technology and efficient pneumatic equipment can save about 30% of energy. The pneumatic turbine drive device is a very effective new technology. From the perspective of long-term development, such efficiency improvement can only be achieved with the help of pneumatic technical experts.
High power density and high speed motors
Compared with electric drive devices, pneumatic devices and pneumatic tools are characterized by high power density, high speed, strong overload protection, arbitrary on/off start, durability, and insensitivity to moisture and dirt. In addition, the explosion-proof characteristics of pneumatic devices make them an ideal choice for flammable and explosive dangerous situations.
However, aerodynamic technology also has some defects, such as poor economy. Different types of pneumatic motors have different utilization rates for compressed air. The consumption of compressed air often exceeds the actual demand, which increases the energy consumption of the air compressor and leads to the increase of the overall energy consumption.
Practical experience shows that the application is the criterion for determining which driver solution to use. For example, the motor speed of a machine tool is 450R /min. On the packaging lines it serves, the sealing process requires 15Nm torque, so the motor speed must be reduced accordingly. In this scheme, it is difficult to meet the above requirements if the ordinary motor is selected, because the motor will always be overloaded during operation, generating a large amount of heat energy and leading to equipment failure. Therefore, the specification of the motor should be determined according to the load torque. The use of pneumatic motors does not exist above problems. All requirements of packaging equipment can be met by economical torque curves of pneumatic motors and small motors.
The pneumatic motor has high efficiency when working at rated speed. Therefore, the careful selection of pneumatic motors in a variety of applications is highly recommended, can significantly save power and operating costs. And only take simple traditional technical measures, people use for a long time, can ensure that the pneumatic motor has better economy.
Pneumatic system analysis to determine the compressed air requirement
Now, air compressor manufacturers are also responsible for helping users reduce the energy consumption of compressed air tools. The compressed air requirements of existing and new compressed air systems can be accurately analyzed and measured through the computer-supported compressed air system analysis project.
The analysis and review results of the compressed air system are of great significance, because the more transparent the cost and saving potential of the compressed air supply system, the more conducive to the energy saving of all gas equipment in the compressed air system, the more conducive to the energy balance and environmental protection of the enterprise.
After measuring the demand, the energy saving potential of the air compressor station can also be explored and the information of reducing the energy consumption of the air compressor station can be obtained. For example, using modern control software dominated by air compressors, industrial computers are used for communication and control to complete accurate data acquisition, analysis and evaluation. This also lays the foundation for complex system management and significantly reduces the energy consumption of the existing air compressor station. In addition, valuable energy can be further saved through heat recovery.
Of course, new technologies and products in the field of compressed air technology also bring great energy saving potential, such as the newly developed turbine pneumatic motor. This product uses turbine blades and compressed air expansion. The efficiency of the device is significantly higher than that of conventional pneumatic motors, with an improvement of about 30%.
