Description

Technical Field

[0001] The utility model relates to the technical field of cooling water recovery of a condensate pump mechanical seal, in particular to a cooling water recovery device for a condensate pump mechanical seal. Background Art

[0002] Function and principle of cooling water for mechanical seal of condensate pump: when the condensate pump is in standby state, a high vacuum state must be maintained inside the pump. If the mechanical seal or packing leaks, the vacuum cannot be formed inside the condensate pump, and the condensate pump will not pump water or the dissolved oxygen in the condensate will exceed the standard. Therefore, the condensate pump must be installed with mechanical seal water to prevent leakage and ensure that the standby condensate pump can be put into operation quickly. Installing a sealed cooling water pipe on the condensate pump can cool the mechanical seal and sealing accessories, and prevent the seals of the condensate pump from being damaged due to excessive friction temperature.

[0003] The condensate pump mechanical seal cooling water (hereinafter referred to as mechanical seal cooling water) overflows to a certain extent after being cooled in the cavity due to the design of the condensate pump and the vacuum tightness requirements. In order to ensure the vacuum tightness, the overflow cooling water is directly discharged to the condensate pump pit and then slowly flows to the negative meter sewage pump pit, causing the condensate pump pit to be waterlogged and damp all year round, serious corrosion of the equipment casing, and waste of water resources.
