Can high outdoor temperatures cause a low pressure difference alarm for the compressor oil?
Thread Content
Please analyze it – what causes this?
It’s probably the oil temperature; high temperatures can affect the cooling effect of the oil. Here, we usually clean it regularly, and if that doesn’t work, we spray water from a fire extinguisher on the oil cooler, along with using a fan nearby. We do this every time the temperature gets especially high in summer
Original poster, what is the normal level for oil pressure? It’s 2 kilograms. However, when the outdoor temperature is high, the temperature of the lubricating oil inside the engine also rises. The return oil from the engine itself has a certain temperature, and combined with the high outdoor temperature, this leads to an increase in the lubricating oil’s temperature and a change in its viscosity. If the circulating water cooling system doesn’t work properly, this will result in low differential pressure!
What does the compressor oil pressure difference refer to?
It’s possible; when the temperature is high, the viscosity of the lubricant decreases, and with all other conditions remaining unchanged, the oil pressure will drop.
When the external temperature is high, the temperature of the cooling water rises, which in turn raises the oil temperature. This leads to a decrease in the viscosity of the oil, and as a result the oil pressure drops, though it does not drop to the level that triggers an oil pressure difference alarm.
:Oh, I just realized it now after learning more about it
When the temperature rises, the oil temperature also increases, which causes the oil to become thinner; the oil pressure will change as well, but not by much! Because it’s impossible to raise the oil temperature that high, right?
