The jacket of the high-temperature canned pump is partially overheated.
Thread Content
The jacket of the high-temperature canned pump is partially overheated, probably just above 1 o'clock, and the pipelines are smooth and not blocked. The temperature of the circulating water is basically unchanged, but there is a temperature difference in the lubrication. Does anyone know what the reason is?
original: “The jacket of the high-temperature canned pump is partially overheated, probably just above 1 o'clock, and the pipelines are smooth and not blocked. The temperature of the circulating water is basically unchanged, but there is a temperature difference in the lubrication. Does anyone know what the reason is?" Analysis: Since the pipelines are all unblocked, how can the circulating water temperature remain unchanged? The lubrication you are talking about should be the temperature of the medium passing through the cooler. I think it is most likely the motor coil. Other Haiyou are welcome to comment.
I have also encountered this problem. For our Shanghai Japanese machine, in ours, only the circulating water inlet is cold, and the rest is hot, but the temperature of the circulating water outlet does not change much. I don’t know why, but the pump is turned on and everything is normal. On this point, ours is fine if it is turned on all the time.
It may be that the medium inside has cooled down and crystallized, adhering to the surface, so that the temperature at this point is high and the temperature at other points is normal. It is recommended to disassemble and check.
The flow of cold water was not enough. Our company used a heat exchanger from a company in Dalian that was not good enough and the two media were together.
Friends who have Japanese-made machines, you can try changing the circulating water to frozen desalted water. After I changed it here, it no longer gets hot. 1. The circulating water has many impurities and is easy to block.； 2. The circulating water cooling capacity is insufficient. After I make the changes here, everything will be fine.
