Hot oil pump is an ideal hot oil circulation pump or as a heat transfer pump, heat exchange equipment is the ideal matching pump. There are many ways to cool the hot oil pump. This is the first to analyze the hot oil pump sealing structure, which is the main method of cooling the hot oil pump. Of course, there are many other methods besides these, which requires us to pay attention when using it Different cooling methods may achieve different results. We should pay attention to this when using it, and also summarize his basic rules by himself. Botou Tianyi Pump Co., Ltd. hopes you can learn more methods.
According to different sealing structure using different cooling methods. Heat pump seal structure mainly has the following four structures:
(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 the media have a good effect. According to the above sealing structure Let us Analysis of the following hot oil pump cooling (1) hot oil pump in the sealed chamber around the cooling water jacket, through the cold water cooling, the sealed chamber temperature can be reduced to 200 ~ 250 ℃.
(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.
