Roots blowers in the sewage appeared aeration reasons
Roots blower in the process of sewage treatment work in the process of aeration, so what is the reason for this situation? Roots blower take you to understand.
1. Selection error
If the selection of errors, air volume, pressure is insufficient to achieve aeration is a normal phenomenon, for example, we need to pressure 44.1kpa Roots fan for aeration, Roots fan selection pressure selection is small, the phenomenon of fan overload motor overcurrent is very normal; air volume selection is too small, resulting in aeration in the aeration pool aeration strength is not enough or local aeration.
2、Check valve problem
One-way valve is a one-way valve, is to avoid gas backflow, impurities into the fan and additional safety protection devices. As the one-way valve and pipe flange connection is a rubber seal to ensure sealing. Roots fan pipeline when the pressure is low leakage, but when the pressure is high open; turn off the fan after the formation of negative pressure in the pipeline valve closure. When installing the check valve, pay attention to the direction of the outlet can not be installed in the opposite direction, the installation of the reverse gas discharge, not only the aeration is not successful, there is a possibility that the motor burned out!
3、Fan itself failure
The longer the Roots fan is used, some of the parameters of the fan will have problems, such as: insufficient air volume, insufficient pressure, etc. These are normal phenomena, because the Roots fan will be worn out during the use of the fan, so the longer the Roots fan is used, the greater the chances of deviation of the parameters.
4. Piping problems
In the use of Roots fan, piping problems also often occur, such as: inlet cartridge clogging, clogging of the outlet pipeline, pipeline leakage pipeline breakage, pipeline is too long, too many elbows, pipe diameter is too thin and so on will cause the fan system corresponding problems.
5. Circuit problems
Motor wiring error caused by the motor can not start or abnormal current, motor steering error caused by fan reversal, aging of electrical components resulting in low output voltage.
