Mechanical seals for the performance of the work, played an important role, how to install mechanical seals, without attention to the relevant details required, will lead to the damage of seals, the same will bring a lot of harm to mechanical equipment, etc., so We must pay attention to the following three major issues in the installation of mechanical seals.
Mechanical seal for the performance of the work, played an important role, how to install mechanical seals, without attention to the relevant details required, will lead to the damage of seals, the same will bring a lot of harm to mechanical equipment, etc., so We must pay attention to the following three major issues in the installation of mechanical seals.
(1) to determine the size of the installation
Installation, should be based on product manual or sample, to ensure that the mechanical seal installation dimensions.
(2) Before loading, shaft (sleeve), gland should be no burr, bearing in good condition; seals, shaft, sealing chamber, gland should be cleaned. In order to reduce the friction resistance, the axis of the mechanical seal parts to be coated with a thin layer of oil to lubricate, taking into account the compatibility of rubber O-ring, if not oil, can be coated with soapy water. Floating static ring without anti-pin structure, not coated with oil, should be dry-loaded gland.
(3) first with the stationary ring and gland mounted on the shaft, be careful not to collide with the shaft, and then move the ring assembly into. The tightening screws of the spring seat or the drive seat shall be tightened evenly in several passes.
Before the gland is not fixed, push the compensation ring for axial compression, release the compensation ring can automatically rebound without jamming phenomenon, and then gland bolts evenly locked.
