Vacuum pump selection method Raiders wide

【Vacuum pump is a vacuum pump in various ways in a closed space to improve, produce and maintain the vacuum device has been widely used in metallurgy, chemical, food, electronic coating and other industries, plays an important role in the production of the enterprise The role of much market users respected and loved. However, many consumers in the purchase process due to the lack of professional guidance, often paramount, painstakingly. Xiaobian on this issue to discuss with you. Vacuum pump selection method Raiders Raiders vacuum pump selection method is as follows: 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 range of working pressure, therefore, pump operating point should be selected within this range, but not allow it to work long hours outside the working pressure. 3. When you choose an oil seal pump, you should first understand whether your vacuum system has oil pollution requirements. 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. Understand the pumping gas composition, the gas contains no condensable steam, with or without particulate dust, 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. Understand the composition of the gas being drawn, the gas contains non-condensable steam, with or without dust 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. The above is the basic method of selection of vacuum pumps, of course, the specific circumstances of the specific analysis, according to the actual situation to carry out selection.
