water ring vacuum pump power

Posted on Fri, 18 May 2018 07:48:56 +0000

The water ring vacuum pump can obtain the ultimate vacuum of 2000~4000Pa, and the series air ejector can reach 270~670Pa. The water ring pump can also be used as a compressor, which is called a water ring compressor. It is a compressor with low pressure, and its pressure range is 1~2 x 105Pa mete...

Measurement of vacuum degree

Posted on Fri, 18 May 2018 07:48:11 +0000

The vacuum gauges used in vacuum pumps can be divided into two categories: One is the absolute vacuum gauge that can directly measure the system pressure, such as the Mcleod vacuum gauge. The other kind is the relative vacuum gauge used after the absolute vacuum gauge calibration, the thermocoupl...

Vacuum pump high vacuum system

Posted on Fri, 18 May 2018 07:45:27 +0000

Many users often question whether their high vacuum system needs a bypass line. To understand whether the system requires a bypass line, we must first understand the role of the bypass line. Whether the bypass line is used depends on the pumping time of the vacuum system. If the pump cavity is sm...
