compressor

Abstract

The utility model discloses a kind of compressors, which are provided with: first capacitance sensor, immersed in liquid medium and fixedly connected with shell;The surface of at least one electrode of first capacitance sensor is provided with a plurality of first through holes to allow liquid medium to enter first capacitance sensor;Second capacitance sensor, the top of its electrode plate gap extends to the liquid level outside of liquid medium, the bottom is immersed in liquid medium and fixedly connected with shell;The surface of electrode immersed in liquid medium in second capacitance sensor is provided with a plurality of second through holes in at least partial area to allow liquid medium to enter second capacitance sensor;The relative dielectric constant of liquid medium is obtained by the first capacitance value measured by first capacitance sensor, and the oil quality of liquid medium is judged accordingly, and the oil level of liquid medium is obtained by the second capacitance value measured by second capacitance sensor.The compressor can effectively avoid the operation risk caused by poor oil quality or low oil level.
