More Information
Summary:An open cooling space or spiral cooling channel is formed between channel walls of a spool and an outer housing of a rotating shaft seal. The spool is sealed to the housing at the two ends thereof, does not intrude into the cooling inlet or outlet, and is axially removable and exchangeable without being distorted, thereby avoiding damage to the spool and/or contact between the spool and rotating seal elements. Due to the easy installation and removal of the spool, it can be installed as an upgrade after seal installation, and is easily cleaned and replaced. The cooling channel can be terminated by inlet and outlet rings, such that the spool does not require any rotational alignment within the seal assembly. The cooling channel can have a square or rectangular cross-section, thereby increasing thermal exchange between the cooling channel and the cooling channel spool rendering the cooling more efficient.
