The reciprocating compressor lubricating oil is also a reason for the decline
Thread Content
The reason for the drop in the lubricating oil level in the crankcase of a reciprocating compressor is that 360 L of oil needs to be added every two months. Please analyze the reasons for this.
Check the cooler to see if there is oil in the cooling water; it’s possible that a pipe is leaking and the oil has gotten into the water. . . .
If there is less oil and the amount is quite low, then it’s definitely due to a leak. Besides what was mentioned above, other possible causes include leaks from the oil scraper rings, the sight glasses, and various oil pipe connections. A careful inspection will definitely help identify where the problem lies. :lol
First, check for any leaks in the oil circuit, then open the side cover of the middle section to inspect it. If there is a cooler, check the inter-stage cooler as well. Open the water circuit drain lines to initially determine whether there are any leaks in the pipes
Two reasons: 1. The oil cooler is leaking. You can release the coolant return water to check for oil bubbles. 2. Oil seal failure leading to leakage. Open the middle body and check to see if there is lubricant present, as well as its quantity.
Take a close look at the oil seal of the main shaft bearing; there might be oil leakage. This location is relatively hidden and not easy to observe; in some larger models, the oil that leaks from this area ends up directly in the motor stator, making it difficult to detect.
Reciprocating machines generally consume a lot of oil, and are often referred to as \"oil monsters.\" Apart from leaks, oil evaporation is another issue; 360 liters of oil needing to be replenished every two months is indeed quite much. Leaks from things like oil scrapers usually end up back in the oil tank. It’s also necessary to check for leaks in the oil cooler, clean the oil cooler to lower the oil temperature, and consider the possibility that someone might be stealing oil, haha!
I agree with the above statement. The compressor in our unit experienced a rapid drop in the level of crankcase lubricating oil some time ago. After checking the external pipelines and oil coolers, no leaks were found. When the middle section was opened for venting, a large amount of lubricating oil flowed out. The liquid level in the collector is also rising rapidly; it is presumed that there is leakage from the oil skimming ring and the packing of the central body. After replacing the seasoning, it is working properly.
