What are the causes of oil leakage from the steam turbine breathing valve?
Thread Content
First of all, the oil return pipe is not blocked.
Is it because the dry gas seal in your place is not good, causing the oil and gas to cross? But looking at the pictures is pretty cool...
The range hood may be too small! Or the outlet valve of the range hood is not fully open, or the protective nitrogen gas in the fuel tank is leaking! Causes excessive positive pressure in the fuel tank! Caused by poor oil return!
Is there a sight glass on the oil return line? Observe the amount of oil return.
The pressure in the fuel tank is too high, causing the oil return pipe to become clogged. Check whether the exhaust fan of the fuel tank is turned on normally and the direction of rotation is correct.
The oil temperature is too high, the smoke is too large, and the oil tank smoke exhaust fan cannot discharge it in time, or the oil return volume is too large and the pipeline is blocked.
Check the sealing, it's still a sealing problem.
It is recommended to check the outlet opening of the exhaust fan. If it is small, it may cause poor oil return.
It is recommended to check whether the oil return pipe is smooth, whether the range hood is operating normally, whether the oil temperature is a bit high, and whether the amount of nitrogen protection is excessive.
Are there other leak points? What does a leak look like? Has the cause been found? Our unit had an oil leakage from the coupling guard last winter. Later it was found that the reason was that the outlet pipe of the exhaust fan was blocked by frost due to the low temperature.
