We know that the liquid ring vacuum pump was used as a suction pump in the initial stage. Now most of the media in the field of application are liquid, so we have to deal with water frequently, which makes us have to consider the relevant hydraulic factors, so the following small series will introduce the hydraulic requirements of the pump equipment.
1. The flow passage of liquid ring vacuum pump is wide, so the passage of large particles should be considered, and the flow capacity should be strong.
2. The flow characteristics of the slurry should be considered at the outlet of impeller and volute for re abrasion.
3. The impeller is usually cylindrical blade. The impeller is designed with front and back blades to reduce leakage and balance axial force.
4. It is designed as concave arc exit. The settling velocity should be considered in the flow velocity of slurry in the channel to prevent solid precipitation and block the flow channel.
The above is the introduction of the four hydraulic requirements of liquid ring vacuum pump. This kind of pump equipment can play a different effect in special environment. If we master its hydraulic characteristics before use, it will be more convenient for the staff to use. Therefore, we must master the above contents.
