How to solve high oil temperature in the coupler
Thread Content
What can be the reasons for high oil temperature at the outlet of the coupler of a gas centrifugal fan? How to solve it? I seek the advice of experts
This situation has occurred in the summer: when the fan speed decreases or the plate heat exchanger gets scaled, the oil temperature fails to rise. As a temporary solution, cold water can be used to flush the heat exchanger; it’s best to inspect the heat exchanger as well
Inspect the heat exchanger, increase its quantity, and check for instrument issues
Check the quality of the lubricating oil and the efficiency of the heat exchanger, as well as the cooling effect of this chilled water.
It is best to keep the oil temperature at the outlet of our coupler around 75 degrees; aside from blockages in the heat exchanger or insufficient water flow, there should be no design issues
`The oil temperature at the outlet of the coupler here used to be around 63°, but it has risen to around 73° in recent days. What measures should be taken?
Clean the heat exchanger and increase the water flow rate. It is best to add a filter before the heat exchanger to reduce the number of times it needs to be disassembled and assembled.
Is there a solution to installing a filter in front of the heat exchanger without stopping the fan?
Measure the shaft vibration and shaft displacement; minor issues with the bearings can also cause this. Do you use an oil filter when refueling? The oil quality might be poor now. Adjust the speed to see if it’s too high. There should be circulating water cooling; maybe someone turned it down.
