Main parameters of vacuum pump

In the process of understanding of the equipment, the overall production of all parts of the application is very wide, and from the vacuum pump to grasp time can also be noticed that in every part of the overall performance parameters is very important. Friends should be paid attention to only in various parts of the pump body parameters can know clearly, finally the answer to every friend can find more idealistic, so the operation also has the very vital significance.


From the aspect of vacuum pump performance, it can be noted that the ultimate pressure is often a very important index, which is closely related to the pressure index produced in the actual working process. So when in operation should be better grasp the content, and extraction rate is also very important, in use process can meet the production requirements with the quickest speed should be seriously rise, should better hold up on this question.

Main parameters of vacuum pump:


(1) extraction rate: the extraction rate of the vacuum pump is also called the production capacity. At a certain temperature, the volume of the gas pumped by the vacuum pump in a unit time from the equipment can be expressed in units m cubed /S or m3/h.


(2) residual pressure: also known as extreme vacuum, the minimum pressure that the vacuum pump can reach in a stable state, expressed in Torr or %. 1 ATM torr = 1/760 = 133.3 Pa.


(3) amount of gas extraction: at a certain temperature, the specified amount of gas that the vacuum pump can extract from the equipment in unit time is called volume of gas extraction, unit m3/h.


(4) starting pressure: the pressure when the vacuum pump starts to work.


Friends also, of course, it should be noted that the parameters of the pump body involved in species is often a lot, from the aspects of various parameters can be noticed that in front of the swept volume, start-up pressure and pressure, compression ratio, coefficient of the ho, reflux ratio, the parts are very important, friends should hold up better in each part, after only know clearly in every aspect, finally able to find the answer to a more ideal.


In this way, the performance parameters of the vacuum pump can be understood in various parts, I hope that every friend can better operate these basic information. Know clearly in each part, and eventually people will be able to find more appropriate answer, of course only all parameters in the normal range, this equipment is can choose and buy, this part of the content should be clear.
