1. In a four-stroke cycle of repeated movement of the piston rod, check the level and vertical axial vibration of each piston rod to check the actual effect of the comprehensive maintenance of the fitness exercise organization.
2. Accurately measure the amount of vibration in the vertical position: the inner diameter gauge is accurately installed at the top of the piston rod at 12 o'clock, close to the sealing packing, and the needle on the inner diameter gauge must vertically bisect the piston rod body.
3. The connection between the plunger pump rod and the crosshead must be properly opened, and the crosshead must be placed and evenly adhered to the guide rail. The gap between the slide rail and the slide rail cannot be inserted into 0.04mm at six o'clock, and the gap between the four corner feeler gauges inserted into the slide rail must be the same.
4. Press the "rocker" of the case, the needle on the case will rotate on the surface of the case so that the needle faces the zero mark on the surface of the case.
