(1) Assembly of gland and bellows: The gland and bellows are connected with 6-12 bolts, and there are gaskets between them to prevent medium leakage.
(2) Hard ring positioning: First fix the fixed ring on the positioning counterbore of the shaft sleeve, then put the gland and bellows assembly so that it is close to the fixed ring, put the hard ring, wedge ring and rotating seat ring , After determining the position of the rotating seat ring, tighten the ring tightening screw slightly, connect the rotating ring and the hard ring with screws, and take out the fixed ring, gland and bellows assembly.
(3) End face alignment: When the rotating seat ring and the hard ring are connected to the shaft sleeve, keep the end face vertical. Generally ensure that the end face runout is less than 0.05mm. On the assembly platform, after tightening the set screw on the rotating seat ring, use a dial indicator to align it while tightening the screw connecting the rotating seat ring and the hard ring to ensure the end face is vertical Spend.
(4) Adjustment of compression amount: The compression amount of the cartridge bellows mechanical seal is reflected in the thickness of the positioning block. But some users require a different amount of compression.
