Use simple 5 installation problems and 11 seal selection caused by leakage detection
Feb 06, 2023
Want to use a simple method to detect leakage of seals is very simple, first of all, we know how much of the seal products, and then in the selection of seals on how much.Let's get down to brass tacks. Let's talk about the installation and selection of seals.
Installation issues
(1)The seal assembly direction error causes the leakage.
(2)During installation, foreign matter and dust are mixed into or in the pipeline to cause leakage into the sealing chamber.
(3)Poor assembly caused seal damage caused by leakage.
(4)Seal surface scratches caused by leakage.
(5)The piston rod is not concentric, the eccentric load causes the leakage.
Selection of seals
(1)The pressure is too high, the hardness of the seal is too small to be extruded out of the metal groove.
(2)The sealing material dissolves with the medium, and the sealing element is softened or dissolved.
(3)Seals are used in conditions where the temperature is too high and the sealing material is carbonized.
(4)Low temperature causes the sealing material to harden and shrinkage causes leakage.
(5)The use of line speed is too high, leading to heat seals, dry grinding, carbonization of the formation of leakage.
(6)Poor lubrication in service conditions results in leakage due to wear and tear of seals.
(7)The cavity being used is vibrated to cause leakage.
(8)Because the dust causes the seal to wear to cause the leakage.
(9)The hardness of the seal is too high to fill the metal groove completely and cause leakage.
(10)The size of the seal does not match the metal groove causing the leak.
(11)Select the storage time is too long, aging seals caused by leakage.
