With the development of social productivity and the advancement of science and technology, machines have been working under high load due to the needs of production. If you want to check the runout of the stainless steel piston rod, first check the horizontal radial runout and vertical radial runout of the stainless steel piston rod in one stroke of the piston reciprocating motion at all levels to check the comprehensive maintenance effect of the motion mechanism.
The way to measure vertical runout is: a dial is mounted on the top of the stainless steel piston rod at the punctual position, next to the pressurized packing, and the needle of the disc needs to be perpendicular to the stainless steel piston rod shaft. Measure the amount of runout in the horizontal direction: the dial is set at the 3 o'clock or 9 o'clock position of the piston rod against the pressure sealing packing, depending on the "closeness" as close as possible.
