Oil-sealed vacuum pump selection

According to the production process requirements and market supply, the general is in accordance with the advanced technology, economic efficiency, the use of production, operational feasibility, maintainability and simplicity, operation Strong and energy supply and other requirements, to investigate and compare the analysis, the best choice of equipment. In the selection of oil-sealed vacuum pump people have a lot of places to pay attention. Oil-sealed vacuum pump Next, we will introduce a few things to note: 1, the ultimate pressure of the vacuum pump should meet the working pressure of the process. The pump pressure is usually selected to be lower than the process requirements of about an order of magnitude. 2, each pump has a certain range of working pressure, therefore, the pump operating point should be selected within this range, but not allow it to work long hours outside the work pressure. 3, when you choose oil seal pump, you should first understand your vacuum system is required for oil pollution. If the equipment is strictly required oil-free, should choose all kinds of non-oil pump, such as: water ring pump, cryogenic pump. If the requirements are not strict, you can choose to have a pump, plus some oil pollution control measures, such as adding cold trap, oil trap, baffle, etc., can achieve clean vacuum requirements. 4, was pumping gas composition, the gas contains non-condensable steam, with or without particles, whether or not corrosive. When choosing a vacuum pump, you need to know the gas composition and select the appropriate pump for the purged gas. If the gas contains steam, particles, and corrosive gases, consideration should be given to installing auxiliary equipment such as condensers, dust catchers, etc. on the pump air inlet piping. 5, when the selection of oil seal vacuum pump, to consider the vacuum pump out of the oil vapor (fumes) on the environment how the impact. If the environment does not allow pollution, should choose oil-free vacuum pump, or the oil vapor to the outside. Selection of oil-sealed vacuum pump not only in economy, work efficiency and other aspects has an important role, but also for the development and promotion of the entire industry plays an important role, how to make this product more innovation and efficiency, deserving more professionals The importance of.
