What are the advantages of oil-free vacuum pumps? Oil-free vacuum pump products are applicable to a wide range of products, but in the purchase of special attention, the product has been different from the past, the society in progress, science and technology in the development, people's living standards are also improving, with the increase in the demand for products, promote the product also with The Times. Taiwan ruixu vacuum equipment co., LTD. 's products after years of research and development and innovation, products can not only meet the needs of enterprises, but also in the after-sales aspects are guaranteed.
Oil free vacuum pump in the purchase need to pay attention to what?
1. The working pressure of oil-free vacuum pump shall meet the requirements of ultimate vacuum and working pressure of vacuum equipment. For example, a certain vacuum drying process requires a working vacuum of 10mmHg, and the ultimate vacuum of the oil-free vacuum pump should be at least 2mmHg, preferably 1mmHg. Generally, the ultimate vacuum of the selected pump is half to an order of magnitude higher than the operating vacuum of the vacuum equipment.
2, the correct choice of oil-free vacuum pump operating point. Each pump has a certain working pressure range, such as: 2BV series water ring oil-free vacuum pump working pressure range of 760mmHg~25mmHg (absolute pressure), in such a wide pressure range, pump pumping speed changes with pressure (refer to the pump performance curve for detailed changes), its stable working pressure range of 760~60mmHg. Therefore, the pump operating point should be selected in this range is more appropriate, and can not let it in 25~30mmHg long-term work.
3, oil free vacuum pump in its working pressure, should be able to drain all the gas produced in the process of vacuum equipment.
4. Requirements for oil pollution of vacuum equipment. If the equipment strictly requires no oil, should choose a variety of no oil pump, such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, cryogenic pump. If the requirements are not strict, you can choose to have the oil pump, with some anti-oil pollution measures, such as cold trap, baffle, oil trap, can also meet the requirements of clean vacuum.
