Pumping rate of Roots vacuum pump unit

Roots water ring vacuum unit is made up of roots pump main pump and water ring pump as series pump.


The water ring pump is more advantageous than other vacuum pumps in Roots water ring vacuum unit. It overcomes the limit pressure difference (the limit pressure of the unit is much higher than that of the water ring pump) when a single water ring pump is used, and has the disadvantage of low pumping rate under certain pressure. At the same time, it keeps the Roots pump working quickly and pumping greatly. The advantages of gas rate.


Especially suitable for pumping a large number of condensable steam, especially when the gas-filled oil seal mechanical vacuum pump is not enough to remove condensable steam, or the use of solvent can deteriorate the performance of the pump oil, or the vacuum system does not allow oil pollution more obvious. When equipped with explosion-proof motors and electrical appliances and comply with the corresponding safety rules, flammable and explosive gases can also be extracted.


Roots Vacuum Pump Unit in the selection of time to consider a variety of parameters, such as its efficiency, pumping rate and other issues, each problem may be the cause of equipment failure, therefore, in order to better use the equipment, we need to further understand and understanding of it, today I focus on for you to enter A simple analysis of the pumping rate of Roots vacuum pump unit is hoped to be helpful to all of you.

Analysis of pumping rate of Roots vacuum pump unit:

The pumping rate of Roots Vacuum Pump Unit varies greatly because of the different pre-stage pumps and the different working pressure range. The design should be based on the specific working conditions and the requirements of the vacuum system, and strive to make Roots Vacuum Pump Unit reflect good applicability and economy.


When Roots vacuum pump is used in vacuum engineering, it is usually connected in series with vacuum pump such as rotary vane pump, slide valve pump, water ring pump or other dry pump with direct air exhaust. It is used as mechanical booster pump in medium and low vacuum range. Its working principle is the same as Roots blower. The actual pumping rate of Roots vacuum pump is closely related to theoretical pumping rate and zero flow compression ratio.
