RY20-20-125 air cooling heat transfer oil pump cooling method
RY20-20-125 air-cooled heat transfer 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 ℃; for single-end seal, the use of infusion flushing Clean. The temperature of about 100 ℃ wax oil (generally do not have diesel, because diesel is finished), both to reduce the temperature, but also improve the working environment, is an effective way; gable outside the use of water quench; In addition to reducing the temperature, but also Can prevent the sewer pipe blockage.High usage can prolong the service life of the heat transfer oil pump.Here are some methods of cooling the heat transfer oil pump: (a) Single-end seal: using injection flushing, flushing fluid is about 100 ℃ less second line Wax oil, the pressure is higher than the sealed chamber 0.05 ~ 0.15Mpa. Gland outside with hot water (soft water) for rapid cooling. Generally can use a cycle (ten months). (B) double-sided mechanical seal: External cooling, life is 1.5 ~ 2 times single-end surface. (C) 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. Vice selection of hard to hard (YG6 / YG8.SiC / SiC, etc.), high viscosity, A small amount of medium or medium solid particles produced crystals, have a good effect.
