Ask now. With the increase of production workshops and the continuous application of new technologies, more and more contradictions have emerged.
1 Purpose and Necessity of Air Compressor Retrofit and Reconstruction In the initial stage of piston compressor use, the design flow rate is greater than the actual gas consumption, and there is a certain energy waste. In the later stage of equipment use, the piston cylinder body is seriously worn, resulting in airtightness first. The actual gas production is far from the small body and its design is good.
The use of natural gas feed channels since 1999 requires the use of compressed air as the atomizing medium, which consumes a portion of the compressed air. In 2000, the company produced 25, 1 and 50, brine bottles, and the speed of the brine bottle was 5,563. If the gas consumption is large, the progress will intensify the contradiction between the actual gas consumption and the foot. At this time, the lowest air pressure is 2,02 è…½, which has restricted normal production.
The normal working pressure of the bottle making machine is 28, or above. If it is lower than 234, the glass blank will stay in the initial mold for too long, and the middle blowing pressure will not reach, which will cause defects such as neck and neck.
12 technical transformation ideas and finger parameters through a large number of analysis and research, proposed to solve the lack of gas supply has the following three options, open the compressor, that is, the use of spare compressors, the disadvantage is that the energy consumption is greater. The second increase the compressor motor pulley diameter to increase the spindle speed to increase the gas production. The disadvantage is that the high speed progression accelerates the wear of the piston block. The third increase in the inner diameter of the cylinder block of the compressor, and the increase in gas production is also passed through. The anti-argument of the captain scheme is considered to be Dilin, (1) å¦¯åŠ å®¤ and temporary = J Gui is the third option. coefficient. After the transformation of the soil clearance coefficient, the compression ratio of the index compressor of the vertical cylinder expansion process is taken as the mechanical efficiency of the adiabatic index, 80; after the transformation, the total cylinders = 1, 1! =, the rate is in the original motor rated power range, the transformation program can be treated.
2 pressure; the machine is widely used to calculate the pain formula = 2 father and father illusion! Body diameter Piston stroke speed Before the mechanical efficiency transformation, 2 Cry Cylinder = After the transformation, the increase of 37.583076=682 knowledge 1 red was achieved by changing the gas to achieve the intended purpose.
The transformation method replaces the 2131 with a compressor cylinder diameter mountain, 35, 1 sen into a 4 to 1 cylinder, and some of the attachments have been replaced by this practice, which is practical and feasible, and the effect is very obvious.
13 Investment and economic benefits Annex production costs 300 yuan 3 attack and construction 1 fee 2, å…€, accounting for 17,820 yuan to meet the normal production after the transformation, increase the speed of 12 to mention the product quality, so that the yield rate increased 12 2 energy saving The purpose and necessity of the consumption of pipeline networking 21 networking is that the gas supply mode is suitable for manufacturers with relatively small distances in the production workshop. This kind of gas supply mode has a large number of energy-saving units, and each foot has the best performance of the equipment. Pay the hunger and gather the heart of the factory. Concentrate the excess energy in a single unit, and achieve less energy to reduce the backup machine to save energy.
22 ideas and methods of technological transformation The so-called pipeline networking is to concentrate all the compressed air produced by the air compressor, and then distribute it to each production workshop.
The best way to connect the network is to put all the gas produced by the air compressor into a large-capacity gas-regulated gas tank, and then pump it to each production workshop through the pipeline. Due to the difficulty in manufacturing and installing the large-capacity regulator tank, the 2,13 gas storage tanks matched with the original compressor can be used to connect them in series to achieve the effect of voltage regulation.
23 Networking advantages and economic benefits After the network is connected, the whole plant adopts a unified air pressure to ensure normal production of gas. In particular, after the modification of the single air compressor in the first step, the gas production is obviously increased, and the power is saved in the single machine. 12 compressors are saved, and a large amount of water fee and equipment maintenance cost are reduced after networking.
2 Er saves equipment maintenance costs 50003000 yuan or more two parts of the work are complementary. The above two schemes were implemented in the Xilinbo workshop in December 2001, and the effect was quite remarkable. Before the transformation, the configuration was 3 for 1 and the replacement for 2 and 1 for normal production, saving one air compressor. After the transformation, the average monthly power saving was 51.03 million compared with the previous month. According to the actual reading of the workshop electricity, the actual electricity saving for the whole year was 31.415 million yuan.
3 The pressure of the compressor after the frequency conversion speed regulation technology transformation needs to be stabilized, otherwise the negative impact surface is larger. Due to the large number of production lines and frequent production changes, the gas consumption fluctuates greatly. If the compressor operator does not adjust the air pressure in time, it is difficult to ensure that the air pressure of the pipe network is stable, causing the pipe network pressure to fluctuate. Frequency conversion of the compressor can effectively solve this contradiction. And save energy. It has several advantages, such as 1 advantage, 1 high rate, and no additional slip loss due to speed regulation.
3 easy to achieve coordinated control and closed-loop control.
After the original system frequency conversion transformation, the 50 power frequency power supply is converted into a frequency-continuous variable frequency power supply through the frequency converter to supply power to the motor, and the pipe network power is composed of the music carrier frequency carrier and the air compressor. The closed loop adjustment system is screwed.
Because the motor output speed is continuously adjustable, the corresponding air compressor air output is continuously adjustable. Therefore, the frequency converter adjusts the speed of the motor according to the air volume of the pipe network, thereby adjusting the air outlet of the air compressor, so that the air volume of the pipe network is equivalent to the air volume of the air compressor, and the constant pressure control of the pipe network is performed. Page 8 Glass and enamel can be used to measure the Curie temperature of the other 3 1 samples. The test error is ±03.
According to the home! The temperature statistics can be published within the experimental error range of 1. The temperature of the sample is lowered by the noisy 0, and the 1st degree of the shoe is larger. From the 1; to the role of the operation, that is, super exchange effect. The Curie temperature of the temperature-sensitive MnZn ferrite material has the following relationship with the super-exchange effect. 5, the Curie temperature 2 is proportional to the number and exchange integral of the number of magnetic ions participating in the human and 8-bit super-exchange. Obviously, the stronger the super-exchange effect, the more the number of ions participating in this exchange, the higher the Curie temperature. According to the crystal field theory, the surface potential of 2+ ions is lower than that of 2+ and 2+ ions, so that it can preferentially enter the gap of the plane to replace the + and 2+ ions, thereby forming a more stable magnetic solid solution. The Curie temperature of a spinel-type ferromagnetic substance depends on the super-exchange effect between the magnetic particles on the human 8th lattice in its lattice structure, and the sub- 21 is a non-magnetic ion, when it is + in the human position, elbow + When replaced by 2+ magnetic ions, the super-exchange effect of human 8 is weakened, which inevitably brings about a decrease in Curie temperature. In addition, due to the substitution of + ions, the lattice of the ferrite can be changed, so that the super-exchange interaction occurs. 3 Conclusions The addition of the 7-inch Mn-Zn ferrite has a fixed influence on the Curie temperature. Due to the addition of 2+ ions, the lattice of the ferrite can be changed, and the super-exchange effect is affected, so the Curie temperature of the sample changes.
From the perspective of the saturation magnetization coercivity, the performance of the Mn-Zn ferrite is greatly improved, and the most prominent one is that the doping can be extracted by the ray diffraction test, and the additive is doped + 1 The presence of ferrite crystal phase in the manganese-zinc iron strontium prepared after the reaction has no effect, but the crystal growth can be improved.

To achieve energy-saving operation.
After the above-mentioned several steps of transformation, the entire air compressor station can not only save energy, but also improve the control precision of the system and the automation process in the production process. 7 physical strength.
