In five top petrol tanks 15.
The reciprocating compressor of the present embodiment, due to the difference of type, causes oil drain quantity the most different.The profit of Compressor Group
The consumption of lubricating oil is from from 5L/D～50L/D, and according to consumption, the lubricating oil being wherein discharged into compressor body accounts for
30%～50%, after filtering, the lubricating oil that can reuse accounts for 80%～90%, lubricating oil 20% that every day can be saved～
40%.Compressor is with plain oil about 8000 yuan/barrel (one barrel of 209L), and special lube is more than 20000 yuan/barrel (a barrel
209L), plain oil single unit can save about about 50～600 yuan every day, and special lube can save about 140 then every day
～1500 yuan.Annual just can save several ten thousand to the cost of hundreds of thousands, if multiple stage unit runs simultaneously, the one-tenth of saving every year
