Edwards vacuum pump is a kind of vacuum equipment widely used in semiconductor, optoelectronics, electronics, medical equipment and other fields. It is produced by the American Edwards Company, hence the name Edwards vacuum pump. Now, it has become one of the most popular vacuum pumps in the world. This article will introduce the principle, characteristics, application and maintenance of Edwards vacuum pump. Principle Edwards vacuum pump is a kind of vacuum pump working according to the molecular impact adsorption principle. It is composed of a rotating rotor and a fixed looking shell. There are a series of different sizes of spiral grooves inside the rotor, when the rotor rotates, the spiral grooves will bring the gas to the inside of the housing, and then through the molecular impact adsorption principle, the gas will be absorbed into the inner wall of the housing, and finally realize the generation of vacuum.
Features 1.High efficiency: Edwards vacuum pump adopts advanced molecular impact adsorption principle, which can realize high vacuum generation in a short time, and improve the production efficiency.
And improve the production efficiency.
2. High reliability: Edwards vacuum pump adopts precise technology and high quality materials, which can ensure its long-term stable work. 3. Easy to use: Edwards vacuum pump has the characteristics of simple structure and convenient operation, which is very suitable for wide application in industrial production. 4. Low noise: The operation process of Edwards vacuum pump is very quiet, which will not cause noise pollution to the surroundings. 5.
APPLICATIONS
Edwards vacuum pumps are widely used in the following fields by
5. Semiconductor manufacturing: Edwards vacuum pumps are used in the semiconductor manufacturing process to help prevent gas and impurity contamination and to ensure the quality of semiconductor devices.
6. Optoelectronics industry: Edwards vacuum pumps are also widely used in optical coating, optical instruments, laser equipment and other aspects.
7. Medical equipment: Edwards vacuum pumps are also used in medical equipment, such as magnetic resonance imaging (MRI) equipment. 8. Laboratory: Edwards vacuum pumps are also suitable for vacuum equipment in scientific research laboratories, to help realize the vacuum environment required by a variety of laboratories, and maintenance. 9.
In order to ensure that Edwardian vacuum pumps work stably for a long time, it is necessary to carry out the necessary maintenance. Specific maintenance matters are as follows 9. regular cleaning: regular cleaning will help to remove the adsorption of gas and impurities inside the casing. 10. replace the rotary shaft seal: if the Edwards vacuum pump fails to achieve the expected results, it may be due to the failure of the seal, you need to replace the rotary shaft seal in a timely manner. 11. keep the casing dry.
11. Keep the casing dry: the inside of the volume casing of the Edwards vacuum pump should be kept dry to avoid unnecessary damage such as oxidation. Conclusion Edwards vacuum pump is a powerful and reliable vacuum equipment. It has the advantages of high efficiency, low noise, easy to use, etc. It is widely used in semiconductor, optoelectronics, medical equipment and other fields. In order to ensure its long-term stable work, it is very important to regularly clean, replace the rotary shaft seal, keep the volume shell dry and other maintenance work.SKU: n/a -
