The mechanical seal for mixers is an ideal way to solve the sealing of the stirring shaft. According to the logarithm of the sealing surface, there are single-end mechanical seals and double-end mechanical seals. Double mechanical seals are generally equipped with a balanced circulation system, which can be used in flammable, explosive, toxic and corrosive, high vacuum and other occasions with stricter sealing requirements. The sealing structure is an external flushing structure. The flushing fluid can be clean water or industrial reuse water. The pressure of the flushing fluid is lower than the pressure of the sealing chamber. The flushing fluid is input at the upper end of the auxiliary sleeve, and is output at the lower end of the auxiliary sleeve for recycling. The seal plays the role of cooling and flushing. The auxiliary devices of the mechanical seals include a thermostat, a balance tank (isolated fluid container), and a forced circulation balance system.
