How to improves dredge pump efficiency by impeller adjustment?
The working principle of the dredge pump belongs to the centrifugal pump, which conceptually refers to a device that converts the energy of the solid and liquid mixed medium by the action of the rotation of the impeller of the pump, and converts the electrical energy into the kinetic energy and potential energy of the medium. The adjustment of the dredge pump impeller is to ensure efficient operation of the pump. This article is a summary of what we have done about impeller adjustment:
In order to ensure the efficient operation of the dredge pump, the gap between the impeller and the front guard plate must be adjusted in time. The gap between the metal liner pump impeller and the front guard plate is between 0.5-1 mm, between the rubber lining pump impeller and the front and rear sheath. The gaps are equal. When adjusting the impeller clearance, first stop the pump, loosen the bolts of the compression bearing assembly, tighten the nut on the adjusting bolt, and move the bearing assembly forward. At the same time, the hand drive shaft rotates in the pump transmission direction until the impeller rubs against the front guard. For the metal lining pump, loosen the nut that has just been tightened in the front half, and then tighten the nut on the front of the adjusting bolt so that the bearing assembly moves back and the gap between the impeller and the front guard is between 0.5 and 1 mm. For the rubber lining pump, the bearing assembly is moved forward by tightening the nut on the adjusting bolt, so that the impeller contacts the front sheath and then moves the bearing assembly backward, so that the impeller contacts the rear sheath, and the total bearing assembly is measured. The moving distance is taken as half of the distance between the impeller and the front and rear sheaths. Then adjust the position of the bearing assembly by adjusting the bolts to ensure the correct clearance value of the impeller and the front and rear sheaths. After restarting, the impeller must be re-examined. Rotate whether the normal bearing assembly compression bolt and adjustment bolt are tightened, and then start the pump.
In summary, it is about the adjustment of the impeller of the dredge pump. The impeller of the dredge pump is the most important component in the operation of the dredge pump. If the impeller wears fault, it will directly affect the operation of the pump.
