Abstract: Energy is an important aspect in our day to day life. It is important to save energy wherever possible that to electric energy. We are suffering from electric energy crisis now-a-days. In order to save electric energy alternate system is chosen and it is implemented which would save electric energy. Wasting energy for supplementary or supporting works like machine door opening and closing considered as uneconomical. Energy consuming system consumes lot of energy for supporting works. In this energy saving concept two different types of system can be coupled to work as a single system which would save much energy than before. Our concept discusses about the same. Energy wastage for operating CNC machine door is taken for consideration in our work and analysis has been done on it. A new hydraulic operating system is proposed to overcome the difficulties.

Abstract: The Institute for Sustainable Technologies – National Research Institute developed a device for erosive wear tests that enables the experimental reconstruction of the erosion process and the empirical modelling with the use of which the assumed operational life of a given material can be determined with reference to the influence of the erosion processes. The author presents the architecture and the functionality of a pneumatic system employed in the device simulating the erosive wear processes. He discusses the functions of individual actuators and the hardware solutions used in this system. Additionally, the research problems encountered during the design and the verification of the prototype of the device are analysed. The instrumentation enables the reconstruction of real operation conditions of structural elements and the simulation of different experimental reactions with the possibility to model their intensity. The developed pneumatic system is an integral part of the device that can be useful for both researchers and designers, because it helps to explain physical aspects of the erosion of materials.

Abstract: This paper developed a tiny-skin transplanter which was used in making and enlarging the tiny square skin before the skin transplantation. It introduced the design process of the transplanter’s pneumatic control system which provided negative pressure to the skin-cutting platform and separating device, and controlled the rising and descending of the cutting system and separating device, and controlled the cutting platform’s rotation.

Abstract: In order to improve the productivity of the filing form materials continuously and automatically packaged line, the control methods for the manipulator and the mechanism which has the capacity of weight self-measuring and auto–filling to the packaged material were studied. The manipulator is a pneumatic control system, it is consists of three pneumatic cylinder circuits to implement the horizontal movements, vertical movements and the activities of picking up or putting down the materials on line. The material to be picked up by manipulator was weighed and displayed by a single chip microcomputer. The general control function of the system was carried out by a PLC unit. The structure changeable type of simulating human being intelligence control methods resulting in the real observing at the objective changes were studied and implemented to achieve the plant high in positioning accuracy and fast in response speed. The experiments were realized and the results showed that the working period time is less than 5.8s,the weight variation measured by single chip microcomputer is not more than 2 grams in 300 grams.

Abstract: There are three work posts in this warm extruder: upsetting station, backward extrusion station and blanking station. They work continuously. The manipulator is mainly used to passing artifacts from one station to another. The warm extrusion forming process manipulator for steel connecting sleeve typically was designed to reduce labor intensity and enhance production automation level. The machines structure and working principle were described. In the same time, some pneumatic circuits and pneumatic control circuits of the manipulator were designed, so the manipulator can have automatic voltage regulating function and run smoothly. Practices show that the strapping machine has the advantages of simple structure, high efficiency, low cost and small vibrating noise.

It brings positive significance for the improvements of productive effect of textile enterprises by verifying various functions with the packaging test developed by the packing production line of sewing thread bar.

Abstract: This paper proposes an approach to calculate the specific thermodynamic energy and specific enthalpy of real gas. In the high-pressure air pneumatic system, the thermodynamic properties of the air which regarded as ideal gas would produce a large deviation to the actual value, thus seriously reducing the authenticity of the pneumatic parameters. In view of this, the specific residual thermodynamic energy and specific residual enthalpy of the high-pressure air were presented on the basis of modified corresponding state equation and virial equation which truncated to the third virial coefficient. In the specific enthalpy calculation for real gas, a difficult part of integration can be avoided by judiciously using advised residual functions. The true thermal physical property parameters of pneumatic system were obtained under the conditions of the wide variations of temperature and pressure.
