Machine, has a broad prospect of large-scale promotion and application.
1 In the former section of the old air compressor, the 5408 type rolling machine that was used in the Yuli Coal Mine was upgraded in 1985. It has high energy consumption, high noise and its anvil characteristics, and the failure rate is also high, which cannot guarantee production. The source of compressed air during the process.
It has many defects and hidden dangers in many aspects. For example, the crankcase is easy to destroy the crankshaft fatigue broken connecting rod and the like. The wind-water-containing large synchronous motor is affected by the high temperature weather in summer and the aging of the electrical components is affected, which is unfavorable for safe production. It can only be unloaded, not automatically stopped. Also can't be! move. Maintenance 1 is large, there is no reliable 1 guarantee, and the unit cost of gas production in the production process is relatively high, so it is necessary to step up the renovation to improve work efficiency and reduce production costs. Moreover, this type of equipment has also entered, and the list of households has been eliminated. According to the characteristics of the coal mine, the power equipment must be required to have a higher level; 1 venting is particularly effective in the prevention of melon 4 in the underground, which seems to be unsatisfactory and the maintenance workload cannot be too high. There are many drawbacks based on the old series of air compressors, and it is an irresistible trend to promote the new series of air compressors.
2 characteristics of single screw air compressor The new series of air compressors is the most advanced technical equipment in the country. It is also an advanced technology in the 1st world. Research and promotion of such technical equipment has a very important meaning for improving the scientific and technological progress of mining areas, improving safety production capacity, reducing consumption, improving the operating environment, and improving the economic efficiency of enterprises. Promoting the new series of air compressors can solve the old series of air compressors. Many questions existed in the machine to achieve better safety production and energy saving targets, and have the effect of reducing noise and improving the environment. The main points are as follows: ensuring safe production and meeting the demand for compressed air in the well; reducing noise, improving the environment, and improving the health of operators; improving work efficiency and energy saving, reducing oil consumption and reducing electricity consumption!
Just above 3040; it is to achieve computerized operation, automatic control of equipment chain control, and improve the technological progress of enterprises.
The 0,340 single-screw air compressor produced by Haifeihe Industrial Group Co., Ltd. is currently relatively advanced. It makes up for the congenital defects of twin-screw technology and reaches the technical level of the world.
Feihe products were awarded the title of Shanghai New Product in 12001 by Shanghai Economic and Trade Commission and won the award of outstanding new products. In the same year, it was awarded the title of National Key New Product in 2001 by the State Economic and Trade Commission. It is the first in the domestic air compressor industry. The batch passed the 69002 international quality system certification of the enterprise.
The 00340 Jia type single screw air compressor is composed of a cylindrical screw and two symmetrically arranged planar star wheels. The meshing pair is made in the casing, and the screw worm groove casing and the star tooth top surface form a closed volume. The screw drives the star wheel to rotate. When the star wheel moves relatively in the worm groove, the gas in the worm groove is compressed and discharged accordingly. There are six worm grooves in the worm, and the two worms divide the worm along the blood to form two working spaces. Each item achieves a gas, compression and exhaust process. Therefore, the single-screw compressor is equivalent to the six-cylinder, and the main technical performance indexes of the piston-compressed fossil-bound single-screw air compressor are as follows: 1 The structure is reasonable and the ideal force balance is achieved.
Since the star wheel is symmetrically arranged on both sides of the worm, the radial gas forces acting on the worm are offset each other, and the axial axial loads acting on the worm groove are also offset. In addition, there is an air passage between the end faces of the worm, so the gas force acting on both ends of the worm is also offset by itself. Therefore the worm does not experience any radial or axial gas forces. The gas force on the star teeth is very small, only about 130 of the piston compressor or twin screw compressor. 2 energy saving. When the single-screw compressor is working, the worm rotates twice per revolution, so that the worm groove space can be fully utilized. Compared with other rotary compressors, the structure size is small, and the worm does not exist theoretically. The clearance volume has a high volumetric efficiency. The single-screw compressor has a complete control system, with servo-type stepless adjustment gas volume, automatic unloading and load conversion, automatic shutdown and automatic start, etc., to meet the needs of users with different gas consumption, significant energy saving, no-load operation, Its power consumption can be reduced by 60.3 with low noise and low vibration. Due to the reasonable design of the compressor mainframe, high light load, the design of the meshing sub-line type is advanced.
The worm produces 12 compression cycles per revolution, with 35,280 exhausts per minute. The exhaust has almost no pulsation, so the vibration is extremely small, and the noise reduction device is used, so the noise is very low, and the quiet coins can be kept upright. It will not fall on the fuselage. 4 long life. The single screw compressor mainframe has a novel structure. The worm axial gas and the radial gas force are each in a completely balanced state, and the bearing is only subjected to the shortcomings of the small gravity air compressor bearing, and the resistance is higher than that of the other types of air compressors. 5 high reliability. Yang 00 compressor design, leading technology, sophisticated production technology, high-precision special equipment, to ensure product quality, daily operation only need to replace the Air Filter movement Oil Filter oil and gas separation fine filter and compressor Oil, so that maintenance costs are reduced, low crows! Degree, the whole layout is compact and reasonable. The compact and beautiful box cover is quick and easy to disassemble and replace parts. It is quick to install and does not need to be installed. It can be used once it is in place. 6 control is perfect, safe operation. The operation control panel is equipped with monitoring devices, which display various relevant parameters and working conditions, operating conditions, and the faults are conspicuous. The over-temperature protection and over-temperature protection of the machine are carefully set. Protection phase failure and successive protection, oil filter block light alarm and so on. In the case of emergency stop, the interlock protection function is added to the over temperature protection overload protection.
In addition, where the control of man-machine interface multi-machine joint control remote and online monitoring, etc., a variety of control modes are available for users to choose.
3 The actual effect of the promotion and use of the miner's wide ground air compressor room, the first in 2003, the introduction of the 0034 grab type single screw air compressor. With the assistance of the manufacturer, after the installation and commissioning operation, the work is straight and stable. After years of observation, it is true that the structure of the machine is simple. It is easy to operate, safe to operate, and the noise is significantly lower than that of the old machine. The energy consumption and lubricant consumption are also very low, which is an ideal substitute.
The 00,01 single-screw air compressor also saves energy in the excitation part. According to the field test results, the normal operating current of the original 5408 air compressor is 20, the voltage of the excitation part 50, the excitation current 100 current is 25, the load ratio is 65, and no special excitation is required. If you run 18 hours on the same day according to the same boot time, the annual operation of the 360-type machine and the opening of one, the power saved by the 340-rated single-screw air compressor is a comprehensive analysis, which can be judged, Jiangxi Province is predicting, The use of electricity and economic growth will be compared with the development of the provinces in the past 8 years. 3=Predicted that Jiangxi will hit 10,000 yuan in 2010; 1 The energy consumption is low. 1 Reference provinces, considering the industrial structure of Jiangxi Province The various reference stagnations are still in the future, and the future adjustment of water is expected to improve energy consumption and consumption, indicating that the prediction results of this study are reasonable and basically credible.
The tfStm per capita, corpse, and the number of production index are calculated according to the average price of the incoming mine in the month of 0.55 yuan. The annual electricity saving benefit of a single unit is 569,400 yuan. In addition, it saves considerable lubricants. The old machine annual fuel consumption 4 6801 new machine only changed times 汕 801 Zhuo Zuo Nian + over 3 2001. In the middle of the year, the annual festival test 14801. According to the market price of the first 220 medium-pressure machine lubricants 5.75; calculated, the annual fuel-saving cost is 8510 kg. The savings in the project amounted to 578,000 7 years. It is not in the water-saving side but also has significant effects on its social and security benefits. The Nanfeng Well in the North Wind Well of the Yuli Mine, as well as the Xifeng Well, still use the old air compressors, even better than the first! Type 8 is even behind, with higher energy consumption and louder noise. Therefore, research and promotion of this type of new technology and equipment has great practical significance.
4 Conclusion Yang 03401 咕 咕 screw new series of air compressors in the preliminary application of the coal-rich coal, safe and economical operation is very good.
