Rotor is a rotating body supported by bearing. Sometimes, in order to use it better, we need to measure the rotor of stainless steel vacuum pump. What method can we adopt?
The measurement of the radial circular runout value of the rotor of stainless steel vacuum pump first places the rotor on two V-shaped iron and divides the circumference of each measuring part of the rotor into several equal parts, such as six parts. Install a dial gauge on the measuring part. The measuring head of the dial gauge should be perpendicular to the axis.
Slowly rotate the stainless steel vacuum pump rotor in the same direction, and record a reading for every equal part of rotation. After the rotor rotates for one week, each measuring point receives six readings, which are recorded in the table, and then the maximum runout value of each measuring point is calculated according to the records. The difference between the maximum reading and the minimum reading of the same measuring point is the radial circular runout value of the measuring point.
Inspection of the axial circular runout value of the rotor of stainless steel vacuum pump Impeller is mounted on the shaft to measure its axial circular runout value, mainly to ensure that the perpendicularity of the impeller end face and the axis center line meets the requirements. Use a dial to point vertically at the side of the impeller and adjust the dial pin to zero. The disc impeller rotates around a circle. The difference between the maximum reading and the minimum reading of the dial indicator is the axial circular runout of the impeller. Note: The percentile meter should be reset to zero after one week of rotor rotation. Otherwise, it indicates that there is axial movement of the shaft or loosening of the watch head, and should be eliminated. The same is true for the measurement of the axial circular runout of the balancing disc.
