The pumps in these industries usually use mechanical seals (referred to as machine seals) to prevent medium leakage and ensure the safety and stability of the production process. However, the machine seal generates a large amount of heat due to friction during operation, which needs to be cooled by circulating cooling water. This part of water used for cooling is called machine seal water.
