Molecular pump application in energy saving lamp manufacturing process
Molecular pump is an alternative to Roots pump in the manufacture of energy-saving lamps. It has a significant effect on energy reduction and synergy through experiments. It has a great promotion significance. It can also promote the application of molecular pumps in the lighting industry and improve production. Performance, reducing energy consumption and manufacturing costs, and ensuring product quality.
At present, in the manufacturing of energy-saving lamp enterprises, most of the use of automatic line row machine, high production efficiency, good product quality consistency. However, the general configuration of the circular row machine adopts the direct vacuum pump and Roots vacuum pump as the unit, which brings new problems: high power consumption; high noise; and large occupation area.

Replace the roots pump unit with molecular pump unit. However, the current standard molecular pump can not be directly used in the circular row machine, because of the working conditions of the circular row machine, the lamp tube will inevitably produce leakage and breakage of high pressure, atmospheric impact and glass debris.
Molecular pump takes the lead in using the whole rotor processing technology in China, which greatly improves the overall strength of the rotor, and greatly reduces the gas backflow between the various layers of the moving plate, and can obtain better vacuum performance faster. It has the advantages of low noise, low energy consumption, small floor area, low maintenance cost, high vacuum, high pumping speed and no oil pollution.
