1. Pay great attention to avoid installation deviations during installation
(1) The tightening of the gland should be carried out after the coupling is aligned. The bolts should be evenly supported to prevent the end face of the gland from deflection. Check each point with a feeler gauge, and the error should not be greater than 0.05 mm.
(2) Check the matching clearance (ie concentricity) between the gland and the outer diameter of the shaft or sleeve. The circumference should be even. Use a feeler gauge to check that the tolerance of each point is not more than 0.01 mm.
2. The compression of the spring should be carried out in accordance with the regulations, and no excessive or too small phenomena are allowed, and the error is 2.00 mm. If it is too large, it will increase the specific pressure of the end face and accelerate the wear of the end face. Too small will cause insufficient specific pressure and can not play a sealing role.
3. After the moving ring is installed, it should automatically spring back after pressing the moving ring to the spring.
