How to reduce the heat pump seal temperature

(1) A domestic hot oil pump is equipped with a cooling water jacket around the sealed chamber, which is cooled by cold water to reduce the temperature of the sealed chamber to 200-250 ° C. (2) for single-end seal, the use of injection flushing, cleaning from the outside world, the temperature of 100 ° C wax oil (generally do not use diesel, because diesel is finished), both to reduce the temperature and improve the working environment, is the Effective way (3) gland outside the use of water quenching; In addition to reducing the temperature, but also to prevent the water pipeline blocked. What are the sealing structure used hot oil pump? (1) single-end seal: the use of flushing, flushing fluid for about 100 ° C by the second-line wax, the pressure 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 choice of hard and soft friction pairs (YG6 / YG8, SiC / SiC, etc.), for high viscosity, medium containing a small amount of solid particles or crystallization of media, with good results.
