As far as the working principle is concerned, slurry pump belongs to centrifugal pump. Conceptually speaking, it refers to a machine that increases the energy of solid-liquid mixed medium through the rotation of pump impeller, and converts the electric energy into kinetic energy and potential energy of medium. The adjustment of slurry pump impeller is to ensure the operation of pump speed. We summarize the adjustment of impeller: in order to ensure the operation of slurry pump rate, the gap between impeller and front guard plate must be adjusted in time. The clearance between impeller and front guard plate of metal lined pump is 0.5-1mm. The clearance between the impeller of rubber-lined pump and the front and rear sheaths is equal. When adjusting the impeller clearance, stop the pump first, loosen the bolt that presses the bearing assembly, tighten the nut on the adjusting bolt, make the bearing assembly move forward, and rotate the transmission shaft in the direction by hand. Until the impeller rubs against the front guard. For metal lined pump, loosen the nut just tightened in front for half a turn, and then tighten the nut in front on the adjusting bolt to move the bearing assembly backward. At this time, the clearance between the impeller and the front guard plate is 0.5-1mm. For rubber-lined pump, by tightening the nut on the adjusting bolt, the bearing assembly moves forward to make the impeller contact with the front sheath, and then the bearing assembly moves backward to make the impeller contact with the rear sheath, and the total bearing assembly is measured. Take half of this distance as the clearance between the impeller and the front and rear jackets, and then adjust the position of the bearing assembly by adjusting bolts to ensure the correct clearance between the impeller and the front and rear jackets. After adjustment, the impeller must be rechecked before restarting. Check whether the rotation is normal, whether the compression bolts and adjusting bolts of the bearing assembly are tightened, and then start the pump. To sum up, it is about the adjustment of slurry pump impeller. The impeller of slurry pump is a very important component in the operation of slurry pump. If the impeller fails and wears, it will directly affect the operation of the pump.
