Reasons for seal coking
Thread Content
What causes severe coking of the mechanical seal in a Changdingxun gasoline pump?
The temperature of the medium gasoline is around 150°C
To address this issue, the components of the raw materials were analyzed, as well as the properties of the crude oil; the problem is caused by water contamination or issues with the incoming oil. It can also be triggered by heating due to the cooling effect of the seal cooling water. Our refinery has switched some of the cooling water to steam for sealing purposes, and this approach has yielded good results, leading to more stable operation. Seals of types 52 and 53 are used, and the white oil used for cooling seals has been replaced with steam; moreover, the small springs used in the sealing structure have been replaced with bellows
Thank you, we deal in bellows
