In rotor pump operation, there has been no flow, what is the cause of this? Today Ace lobe pump's is here to tell you.
1, rotor rotation direction opposite. Rotor direction of rotation is very important for the lobe pump, the direction of rotation is reversed the import of the pump becomes the export, the export becomes the import, then the export naturally will not have the medium out. Check the direction of rotation, correct the wrong direction according to the sign on the pump.
2、Close the valve of the suction or discharge side pipeline. Check whether the valve on the suction or discharge side of the line is closed, and if so, open the valve.
3, no media or low pressure at the inlet. lobe pump although there is a strong self-priming function, but there is a certain limit, too low liquid level, but also make the lobe pump can not absorb liquid resulting in the pump no flow.
4. poorly closed full valves.
5. The viscosity is too high and the pump cannot bite the material.
These are just a few of the reasons why there is no flow in the lobe pump, and you can combine them with the situation of your own equipment to solve the problem.
