Magnetic drive pump impeller how to see steering? Confirm the correct steering is a very necessary thing, is one of the preparatory work before the boot, if the wrong steering will lead to the pump medium countercurrent idling, the existence of safety risks and pump risk, with the pump personnel through the following ways to confirm the impeller steering, the related operation is very simple.
On how to see the steering of the magnetic pump impeller, the intuitive way is to directly observe the motor, can be directly placed in the magnetic pump motor fan by hand, through the wind suction inside and outside to judge the positive and negative rotation, internal suction is positive, outside to anyway, in addition to the coupling protective cover can use cloth, through the direction of the cloth to know the shaft steering, from the pump end to the motor, the direction of rotation is counterclockwise. In addition, it should be noted that most models have a steering arrow on the seal position for reference.
The steering of the magnetic pump impeller is related to the structural design of the pump. The impeller runner and installation decide to turn positive and negative. If there is a steering error, in addition to checking the installation of the impeller, it can be adjusted by adjusting the motor wiring. In addition to the static state to check the steering, if it is in the process of operation, the medium suddenly countercurrent or flow significantly lower, you need to check the steering and speed of the motor is in line with the standard.
After knowing how the magnetic pump impeller looks at the steering problem, the equipment user should also make clear the two reasons that may lead to the reversal of the pump in the process of using the pump.
1. When using the pump, first open the outlet valve and then start the motor, which will make the liquid produce reverse flow at the outlet. The motor should be opened first, and then the outlet valve should be opened after confirming the correct steering.
2. After the completion of the transportation work, stop the pump and then close the outlet, which will let the liquid flow back at the outlet. The outlet valve should be closed first, and then the motor power supply should be disconnected.
