low pice vacuum pump selection guide

EVP vacuum pump manufacturers have their own recommendations for the selection of  low-cost vacuum pumps. Vacuum pump is a device which can improve, produce and maintain vacuum in a closed space in various ways. It has been widely used in metallurgy, chemical industry, food, electronic coating and other industries, and plays an important role in factory production. It is highly praised and loved by the market and users. However, many consumers in the process of purchasing imported vacuum pump, due to the lack of professional vacuum pump knowledge and professional guidance, often choose a device that is not suitable for their own product production.

low cost vacuum pump selection:

In view of the problems mentioned above, I would like to introduce the specific method of low-cost vacuum pump selection.

low pice vacuum pump selection guide is as follows:

1. The pressure of vacuum pump shall meet the working pressure of the process. Generally, the pressure of vacuum pump is about one order of magnitude lower than the process requirements.

2. Each type of vacuum pump has a certain working pressure scale, so the working point of the vacuum pump should be selected within this scale, rather than allowing it to work under the allowable working pressure in a long time.

3. When you choose oil seal pump, you should first understand whether your vacuum system has requirements for oil pollution. If the equipment is strictly oil-free, all kinds of oil pumps should be selected, such as: water ring pump, low temperature pump, etc. If the requirements are not strict, you can choose to have oil pump, plus some anti oil pollution methods, such as adding cold well, oil trap, baffle, etc., the vacuum pump can also meet the requirements of clean vacuum.

4. Know the composition of the extracted gas, including no condensable steam, particle dust and corrosiveness. When selecting a vacuum pump, it is necessary to know the gas composition and select the corresponding pump for the extracted gas. If the gas contains steam, particles and corrosive gas, auxiliary equipment, such as condenser, dust remover, etc., shall be installed on the air inlet pipeline of the pump.

The above is the specific mode of low-cost vacuum pump selection, of course, the specific environment specific analysis, vacuum pump selection according to the actual environment.
