What are the conditions of insufficient aeration in the process of using Roots blower?
2020-11-27
Summary
1. Selection error If the selection of the Roots blower is wrong, the air volume and pressure are insufficient, and it is normal that aeration cannot be achieved. If the pressure is selected during the selection, the fan is overloaded and the motor overcurrent is normal; if the selected air volume is too small, it will cause insufficient aeration intensity or partial aeration in the aeration tank.

If the pressure is selected during the selection, the fan is overloaded and the motor overcurrent is normal; if the selected air volume is too small, it will cause insufficient aeration intensity or partial aeration in the aeration tank.
2. One-way valve problem
The one-way valve is a one-way valve, which is a safety protection device that prevents gas backflow and impurities from entering the fan. Because the check valve and the pipe flange are connected by a rubber sealing ring to ensure sealing. When the air volume is high, the Roots blower is turned on; after turning off the blower, close the negative pressure valve in the pipeline. When installing, please make sure that the direction of the air outlet of the one-way valve cannot be reversed. If it is reversed, air cannot be discharged.
3. The fan itself fails
The longer the Roots blower is used, some parameters of the blower will have problems, such as insufficient air volume and insufficient pressure. This is a normal phenomenon, because the Roots blower will wear out during use, so the longer the Roots blower is used, the greater the possibility of parameter deviation.
4. Pipeline problems
When using Roots blowers, there are often piping problems, such as: inlet filter blockage, outlet pipe blockage, pipe leakage, pipe damage, too long pipes, too many elbows, etc., which will cause corresponding problems in the fan system.
5. Circuit problems
Motor wiring errors will cause the motor to fail to start or the current is abnormal, the motor steering is wrong and cause the fan to reverse, the electrical components are aging, and the output voltage is too low.
