The method of detecting the runout of the piston rod

1. In one stroke of the piston reciprocating motion, check the horizontal and vertical radial runout of the Chrome Plated Piston Rods at all levels to check the comprehensive maintenance effect of the moving mechanism.

2. Measure the runout in the vertical direction: the dial is precisely installed at the 12 o'clock position on the top of the piston rod, close to the sealing packing, and the pointer on the dial must be perpendicular to the piston rod body. Measurement of vertical runout: The dial is set at the 3 o'clock or 9 o'clock position of the piston rod, in close contact with the filler, depending on the "closer" as possible.

3. The connection between the plunger rod and the cross head must be opened correctly, and the cross head must be laid flat and evenly attached to the slide rail. The gap between the slider and the slide cannot be inserted by 0.04 mm at 6 o'clock, and the gap between the four corner feeler gauges inserted into the slide must be consistent.

4. Press and hold the "handle" of the dial, and the pointer on the dial will rotate on the dial surface so that the pointer faces the zero mark on the dial surface.
