As soon as the pump starts to feed, it shuts down no matter how small the flow rate is – what could be the reason?
First, check whether it is a motor issue; secondly, it could be bearing damage or seal damage. It is also necessary to check whether there are any changes in the physical and chemical properties of the material. Also, whether the impeller flow channel is blocked
Is the motor experiencing overcurrent: The pump is clogged, the switch is undersized, there is a fault in the motor current detection, or there is actually a fault with the pump or the motor.
It runs normally when idle but cannot operate under load. First, determine the motor’s operating current, the actual current during idle operation, as well as whether the size of the switches and contactors installed in the circuit is appropriate. If the current is normal, then check the viscosity of the material, its solid content, and the size of the crystals. . . .
We have one pump; its motor was selected for use in pumping liquefied gas. When we tried to use it to pump water for the first time, it stopped working as soon as the outlet valve was opened – this is due to the choice of motor.
What does it mean to experience a jump as soon as material is fed in? Was a trial run using water carried out previously? Was there no problem during the water test?
Check the motor, as well as the relay and grounding
Have you driven around in it? ? The poster didn’t mention a single item that needs to be checked before starting the pump.
Is the current setting for the motor too low? ! ! It needs to be reset in the distribution room! ! ! ! ! !
