1, domestic centrifugal pump set in the sealed chamber around the cooling water jacket, cold water cooling, can make the sealed chamber temperature is reduced to 200 ~ 250 ℃. 2, single-end seal, the use of injection flushing, cited from the outside world clean, the temperature of 100 ° C wax oil (generally do not use diesel, diesel is finished), both to reduce the temperature and improve the working environment, is effective Approach. 3, outside the gland with water quenching; In addition to reducing the temperature, but also to prevent the water pipeline blocked. Sealing structure used are: 1, single-ended seal: The use of infusion flushing, flushing fluid for about 100 ℃ minus second-line wax, the pressure is higher than the sealed cavity 0.05 ~ 0.15Mpa. Gattern outside with hot water (soft water) for rapid cooling. Generally can use a cycle (ten months). 2, metal bellows machine seal: compact structure, easy installation, in the case of the same auxiliary system, the life of 2 to 3 times the normal seal. 3, double-end machine seal: the use of circular washing, plus external cooling, life is single 1.5-2 times. 4, the friction pair selection of hard and hard (YG6 / YG8, SiC / SiC, etc.), on the high viscosity, medium containing a small amount of solid particles or crystallization of media, with good results.
