How to judge whether the air compressor has excessive fuel consumption?

So how to determine whether the machine has too much fuel consumption?

1. First of all, it is ruled out that there is no oil leakage or oil leakage on the surface of the pipe fittings of the machine.

2. Whether the oil level of the machine has dropped significantly, the observation of the oil level indicator line should be compared under the same working environment, for example, under the same load of 7bar pressure, whether the oil level has changed before and after the time, or observe the oil level after ten minutes of shutdown Is there a difference.

3. For the machine equipped with a water separator, take a sample from the drain of the water separator, drain the water and put it in a clean container (cup or mineral water bottle) and settle for about five minutes, then observe whether there are spots or It is oil film-like oil that accumulates on the surface of the container. Generally, when observing against the light, there are a few thin colorful oil flowers, and the sampled water may be milky white before precipitation, which is normal.

4.For machines without a water separator, you can observe the drainage status of the air storage tank, and compare with the previous normal situation to see if more oil is brought out by the discharged water. (1) First rule out that there is no oil leakage or oil leakage on the surface of the pipe fittings of the machine; (2) Whether the oil level of the machine has dropped significantly, the observation of the oil level indicator line should be compared under the same working environment, for example, under the same load of 7bar pressure, the oil Whether there is any change in the time before and after the position, or whether there is any difference in the oil level after ten minutes of shutdown.
