The disclosure discloses a mounting member including two support rails extending side by side. The two support rails include a first section and a second section in an extension direction thereof. The first section is adapted to carry a device with a first size, and the second section is adapted to carry a device with a second size. Grooves are provided on a top surface of the support rails so as to avoid interference between the bottom surface of the device and the top surface of the support rails. The disclosure also discloses a device assembly including a plurality of devices and the mounting member. The mounting member of the present disclosure allows the plurality of devices to be directly mounted on the two support rails without the need of additional support rails or spacers, thereby reducing the number of parts and improving the integrity and ease of installation of the device assembly.

Provided is a monitoring apparatus used to monitor lubricating oil inside a compressor. The monitoring apparatus comprises a first capacitance detector (), a calculation unit, and a determining unit. The first capacitance detector () is disposed in a compressor () and is completely immersed in lubricating oil () inside the compressor (), and is used to detect a first capacitance value (Cn). The calculation unit calculates a relative dielectric constant of the lubricating oil inside the compressor according to the first capacitance value (Cn) detected by the first capacitance detector (). The determining unit monitors, according to the calculated relative dielectric constant, whether quality of the lubricating oil () inside the compressor () encounters an exception. Further provided are a method for monitoring quality of lubricating oil inside a compressor and an apparatus and a method for monitoring a fluid level of lubricating oil inside a compressor. The monitoring apparatus and method may accurately monitors quality and a fluid level of lubricating oil inside a compressor, thereby reducing a monitoring cost and improving monitoring accuracy.

An oil-gas balancing apparatus includes: a body, a gas balancing opening and at least one oil balancing hole. The body has a first end and a second end opposite to the first end, and the first end can be fixedly connected to a shell of a compressor and in communication with an oil sump of the compressor and a chamber of the oil sump. The gas balancing opening is disposed on a first portion of an end surface of the second end. The at least one oil balancing hole is disposed on a second portion of the end surface of the second end. The second portion and the first portion are oppositely disposed. A compressor system can include the oil-gas balancing apparatus.
