A knowledge-based company has designed and manufactured a multifunction transducer that can be used to monitor the power grid in large and small industrial complexes.
“In digital devices, especially digital measuring devices, one of the most important concerns is how to deal with an analog quantity,” Mohammad Reza Hashemi, CEO of Farayand Niroopardaz Company, said.
Hashemi pointed out that the multifunction transducer is based on the latest electronic technology, the Vice-Presidency of Science and Technology reported.
The main function of transducers is to convert one type of energy into another. There is no limit to the type of energy, as they convert each of the electrical, chemical, mechanical and thermal forms of energy.
Transducers are one of the main equipment in industrial electrical automation systems that can be used to sample power grid parameters and convert them into standard signals.
Electrical parameters in this transducer are calculated after the conversion to a digital signal. These quantities are stored instantly in the system’s memory and can be recalled or applied to current or voltage analog outputs after digital selection by all isolated analog-to-analog converters.
Online network monitoring features, measurement of more than 120 electrical parameters of the power grid, remote measurement capability, 2 kV isolation between all parts and four isolated analog current and voltage outputs are among the special features of this domestic transducer.
It offers protection against short-circuit output, measures the total voltage, one-way or two-way active frequency, tolerates transient inputs up to several times the nominal values, has an internal clock equipped with a backup battery and a solar calendar with detectability, synchronization with location systems and occupies little space.
“Knowledge-based companies need to enjoy benefits such as tax breaks to boost domestic production,” the CEO of the knowledge-based company said, while noting that about 15 jobs have been created in the production process.
“The foreign counterpart of the multifunction transducer is priced 12-fold higher and not economical for domestic companies. For this reason and in order to prevent unnecessary imports, knowledge-based companies should be supported.”
Advanced Compressor Competitive
Recently, another domestic knowledge-based company successfully developed a high-speed, high-pressure centrifugal compressor, which has many advantages compared to older models.
“The equipment is used in the oil and gas industry to compress condensates and gas. In some machines, air is compressed and sent to the combustion chamber,” Alireza Nasseri, a member of the board of directors of Kavosh Sanat Toos Company, said.
As a great deal of mechanical energy is expended, the temperature of the compressed gas also rises. High-pressure gas from the compressors is then passed through a cooling system to lower temperature, the Vice-Presidency for Science and Technology reported.
One of the features of a centrifugal compressor is its radial thrust. The air enters the center of the rotating impeller using radial vanes and is expelled by centrifugal forces to the rotating impeller. Before air is pushed to the center of the next rotating impeller, it passes through a diffuser and a coil chamber, in which kinetic energy is converted to static pressure.
The official noted that by achieving capacities as high as 35,000 kW, temporary loads applied to the cycle show higher efficiency and uniform gas movement reduces noise and vibration, which are among the advantages of this device.
High-speed centrifugal compressors are ideal for industries that require a constant application of high-volume pressure.
“This compressor is lighter and has a more compact structure compared to other counterparts. It is more energy efficient and has low maintenance cost because of using fewer parts,” Nasseri said, while stressing that the machine supplies 100% oil-free air and exhibits high resistance to dust.
The new compressor is able to work with a wide range of compressible fluids such as helium, xenon, oxygen and liquid nitrogen.
“Extending support to knowledge-based companies can play a significant role in saving foreign currency and generating employment. The production of high-speed, high-pressure centrifugal compressors has prevented unnecessary imports," he said.
Nasseri noted that promoting knowledge-based products and creating jobs are some of the most important achievements of this enterprise.
Domestic Milling and Turning Machine
A knowledge-based company has succeeded in manufacturing a machine that can simultaneously undertake milling and turning, and rival foreign counterparts.
“The machine has many applications in various industries,” Mohammad Hossein Amani, CEO of Mobtakeran Sanat Rash Machine-Building Company, said, noting that the Computer Numerical Control milling and turning machine has six axes.
The precise cutting machine, which has been patented, is controlled by a preprogrammed computer software that handles all its functions.
The eight-head CNC milling and turning machine is used in many industries, including wood, sculpture, statuary, modeling and molding, as well as masonry.
The foreign model of this device is made only for metals and are very expensive compared to the domestic model, so its use in the wood and stone industries is not affordable.
The high quality, lower price and its ability to work on eight pieces simultaneously make the domestic product competitive.
