What factors cause oil entry into the compressor cylinder?

Sometimes when we start and stop the vehicle here, we notice that the fuel level in the tank drops, yet there’s a lot of oil inside the engine block. Let’s discuss what could be the reasons for this.
A reciprocating compressor? The lubricant for the compressor motor cannot enter the cylinder block; the lubricant inside the cylinder block is supplied by the oil filler. If oil is present when the valve is opened, it indicates that the compressor does not drain water thoroughly, so it is necessary to pay closer attention to the process of draining oil on a hourly basis.
1: The unit pressure is too low. 2: The pressure release speed is too fast. 3: The liquid level is too high when the sump is installed. 4: There is a problem with the oil seal itself.
1. After the engine starts running, oil enters the pipelines and lubrication areas, which inevitably causes the oil level in the tank to drop. 2. Oil entering the cylinders is mainly due to excessive oil pressure, too low reference air pressure, or an excessively high liquid level in the seal oil reservoir
It might be that the pressure of the isolation gas in the dry gas seal is too low, preventing it from blocking the oil from entering the cylinder, or it could be caused by high oil pressure
