The pump manufacturer recommends that the user replace the new ceramic wheel, but the original imported impeller is high, and the delivery period is long and cannot meet the requirements of the user’s maintenance period. The material used is perfectly combined with the mother material, and the impeller size is restored to the original size of the manufacturer. After several months of use, the current, power, desulfurization rate and other data are normal. Roughly estimated that one -time costs were saved by users at one time.
To finally handle the preparation of ceramic pulley. It should be noted that in positive fire or quality adjustment, it is necessary to keep the furnace temperature uniform and use a stationary appliance to make the workpiece uniformly heated and cool. It is strictly forbidden to stack it together. To reduce the weight of the drilling, the drilling order should be arranged after the heat treatment.
The final thermal treatment of the ceramic pulley adopts high -frequency quenching of the tooth surface with smaller parts; the tooth surface obtained after high frequency quenching has high strength, hardness, abrasion resistance and fatigue limit, and the heart still maintains sufficient plasticity and toughness. Essence To reduce deformation. The high frequency quenching of the tooth surface should use lower quenching temperature and short heating time, uniform heating, and slow cooling.
