(1) According to the sealing area, choose the gasket with the specifications and thickness that meets the requirements to ensure the tightness of the sealing device. If the installation is too tight, the felt will drop elastically, overheat, and damage early; if it is installed too loosely, it will cause oil leakage. Therefore, the felt must have proper preload when it is installed. In general, depending on the kind of felt, the natural thickness of the felt should be 1/4 to 1/3 larger than the size of the felt in the sealing device.
(2) The wool felt gasket must be saturated with oil before installation. If the wool felt washer installed in the rotating part is not immersed in oil, the felt and rotating journal will produce high temperature due to dry friction when the machine starts to rotate, causing early failure of the elasticity of the contact surface, causing the felt to lose hermeticity and cause the seal. Oil leaks at the site and does not work properly in severe cases.
(3) Strengthen maintenance. Always inspect the sealing condition of the felt seal and find that the felt is leaking and damaged. Replace it promptly. Overhauled felts should be replaced if they lose their elasticity.
As described above, the flow medium penetrates into the fine gaps, causing leakage leakage of the gasket made of cellulosic material.
The felt pad is a sealing washer made by punching machine. With sealing, oil storage, shock, filtration and other effects.
The installation quality of the felt mat has an important influence on its sealability and service life, as well as the fact that the felt mat is twisted. Before assembly, the sealing groove and the sealing mating surface must be strictly cleaned; at the same time, grease shall be applied to the surface to be passed in the assembly of the felt pad.
