1
Standard Selection: The series in the table represents the recommended standards. Due to the varying working conditions in actual production applications, the gas intake and pressure will undergo many changes. Therefore, during the selection process, calculations or reference to the usage of existing equipment should be conducted based on the actual vacuum extraction process, gas release process, condensation of non-volatile gases, time variations of the intake pressure, etc.
-
2
Pump Specifications: The technical indicators of the single pump are detailed in the respective pump parameter tables.
-
3
Intake Pressure Limit: The maximum intake pressure refers to the highest pressure that the main pump can start at. If it operates for a long time at a pressure higher than this, it will cause the main pump to overload.
-
4
Explosion-Proof Options: If the vacuum pump motor, electrical contact vacuum gauge/pressure transmitter, and electrical control cabinet need to be explosion-proof, please specify during the order. The 2BV5 water ring vacuum pump in the table should be correspondingly changed to the 2BV6 series.
Q: What is the main operational difference between the 267 Pa, 25 Pa, and 0.5 Pa vacuum units?
The difference lies in the configuration of stages and pre-stage pumps. Single-stage pre-pump setups achieve up to 267 Pa, multi-stage roots combinations reach 25 Pa, and three-stage cascaded systems reach a high ultimate vacuum of 0.5 Pa.
Q: Why is it critical not to exceed the maximum intake pressure during continuous operation?
Operating continuously above the specified maximum intake pressure places excessive differential load on the main Roots pump, leading to motor overload, overheating, and potential mechanical failure.
Q: Can the standard 2BV5 liquid ring backing pump be replaced for hazardous environments?
Yes. For environments requiring explosion protection, the system can be configured with the 2BV6 series explosion-proof water ring vacuum pump along with explosion-proof motors and control instruments.
Q: How should I select the right unit model for processes with condensable vapors?
Selection should account for non-volatile gas condensation, total gas volume release over time, and peak intake pressure variations. Liquid ring backing pumps are ideal for handling condensable vapors.
Q: What determines the choice between 2BV and 2BE series backing pumps?
Smaller flow requirements typically utilize compact 2BV series pumps, whereas larger industrial displacement systems (from 300 L/S to 5000 L/S) utilize heavy-duty 2BE1 series pumps to handle higher gas loads effectively.
