This paper mainly introduces the application of molecular pump in the manufacture of energy-saving lamp round car instead of Roots pump. The experiment shows that the effect of energy reduction and efficiency increase is remarkable, and it has great significance for popularization. With this, the application of molecular pump in lighting industry can be promoted, production efficiency can be improved, energy consumption and manufacturing cost can be reduced, and product quality can be guaranteed.
Nowadays, the rapid development of economy brings about huge consumption of energy and threatens the living environment of human beings. It is an urgent worldwide task to improve efficiency, reduce consumption, save energy and reduce emissions to protect the environment. In the application of wide molecular pump, diffusion pump or Roots pump are replaced in many occasions, and good energy-saving and consumption-reducing effects are achieved.
As we all know, the promotion and use of energy-saving lamps in the lighting industry is a measure to save energy and reduce consumption. If all the current ordinary incandescent lamps are replaced by energy-saving lamps, more than 60 billion kilowatt-hours of electricity can be saved throughout the year, which is equivalent to the annual power generation of a Three Gorges hydropower station. However, energy-saving lamps have been introduced to the market for a long time, but their popularity has failed to achieve the desired results. The reason is simple: the energy consumption cost in the manufacturing process of energy-saving lamps is higher, so their relative sales price is also expensive.
According to the relevant information, the high price of energy-saving lamps leads to the difficulty of household consumption, which affects the market promotion. For enterprises manufacturing energy-saving lamps, their previous research and development investment is too large, as well as the production cost is too high. Even if energy-saving lamps save 60% energy than traditional bulbs, their life is 8 times longer than the latter, but their price is 4-5 times the price of ordinary bulbs. In this way, although the energy-saving lamp can save energy and money, but in a certain period of time, considering the immediate interests, the one-time investment is indeed a little larger, moreover, there are doubts in product quality assurance and service life.
Promoting the use of energy-saving lamps is a long-term and arduous energy strategy for the country. Compared with the promotion of energy-saving lamps such as discount, the government should play an active role in this regard, which is not only the top priority, but also can do something. At the same time, the state should formulate corresponding policies and supporting laws and regulations, set up special financial subsidies for energy-saving products, tax relief and other preferential measures, encourage more enterprises to invest in the production and development of energy-saving products, innovate processes, help enterprises reduce production costs, so that energy-saving products have more price advantages in the market competition. In addition, the whole society should support the development of energy-saving and environmental protection research activities in order to achieve energy-saving and environmental protection in the whole society.
At present, in the enterprises that manufacture energy-saving lamps, most of them adopt automatic line of circular row machine, which has high production efficiency and good product quality consistency. However, in general, round row machines are equipped with direct-connected vacuum pumps and Roots vacuum pumps as units, which brings new problems: 1) high power consumption; 2) high noise; 3) large occupied area. For this reason, all lighting equipment enterprises and lighting production enterprises are actively looking for new technology and new methods to carry out technological transformation in order to improve these conditions. Replace the roots pump unit with molecular pump unit.
At present, in the promotion and application of energy-saving lamps, the government gives strong support and corresponding subsidies and policy support. Relevant enterprises are also actively looking for ways and means to save energy and reduce consumption. In the production process of energy-saving lamp, we should tap the potential of reducing consumption and adopt new technology and new means to realize energy-saving in production. This is a successful attempt to save energy and reduce emissions in the production of energy-saving lamps in the lighting industry.
1. Molecular pump experiments introduction
The composite molecular pump adopts the integral rotor processing technology, which greatly improves the overall strength of the rotor, and greatly reduces the gas reflux between different levels of the movable sheet, so as to obtain better vacuum performance faster. The ingenious cavity design in the center of the rotor greatly reduces the probability of damage caused by foreign body falling into the pump. The molecular pump can work in the harsh environment such as large air flow impact or foreign body (broken glass) falling into. At the same time, it has the advantages of low noise, low energy consumption, small occupation, low maintenance cost, high vacuum, high pumping speed, no oil pollution and so on. Preliminary tests show satisfactory results and prove that the design meets the requirements. Finally, the compound molecular pump is used for the replacement test of the energy-saving lamp circulated machine to get the recognition of lighting.2, Molecular pump comparative analysis
(1) the pumping rate of the molecular pump unit is higher than that of the roots roots pump unit, and the vacuum degree is one order of magnitude higher.(2) less noise and less floor space.
(3) operation cost: 280 days a year, 24 h per day and 6720 h a year. Unit: The unit power consumption of Yuan Molecular Pump Unit is 2.38 kW *6720 H = annual power consumption of 15993.60 degrees *1 yuan/degree = 15993.60 yuan Roots Pump Unit power consumption of 8.8 kW *6720 H = annual power consumption of 59136 degrees *1 yuan/degree = 59136 yuan.
Through the above calculation, the investment cost can be recovered from the electricity charge in recent years (59136-15993.60 = 43142.40 yuan). The use of molecular pump units in second years saved 43142.40 yuan in profitability. If the cost of maintenance is considered more substantial, the molecular pump is almost maintenance free. The successful substitution of the molecular pump contributes tremendously to energy saving and emission reduction, achieves a win-win situation in manufacturing applications and expands the new application fields of the molecular pump, which is worthy of promotion.
The energy-saving lamp manufactured by the circular platoon car replaced by molecular pump is tested. The lamp life and quality are improved obviously. The oil pollution of the system is reduced by mass spectrometry analysis. Spectrum analysis shows that the lamp performance manufactured by molecular pump exhaust is greatly improved.
At the same time, according to the practical application feedback of many other special lamps (metal halide lamp, beacon lamp, etc.), car lamp, semiconductor lighting and other customers, molecular pump has played an obvious role in reducing production energy consumption, improving product performance and service life, and has been applied in some well-known lighting manufacturers at home and abroad. Molecular pumps have been well received and heavily replaced.
3. Conclusion
(1) Molecular pump units are directly used in circular row machines to adapt to the unavoidable high pressure caused by air leakage and breakage, the impact of atmospheric flow and glass debris in the manufacturing process, to achieve the goal of reducing consumption, saving energy and guaranteeing quality, so it can completely replace Roots pump units.
(2) Lighting industry has unlimited prospects, product manufacturing technology and product types are developing rapidly, and there is much room for innovation at the level of equipment manufacturing. Together, it contributes to improving the production efficiency of the industry, reducing energy consumption and manufacturing costs, and ensuring and improving product quality.
