Title:
ELECTRICALLY DRIVEN GAS COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2011/125406
Kind Code:
A1
Abstract:
A horizontal electrically driven gas compressor (1) is configured to prevent, even in a low-speed operation state, the occurrence of an operational failure of a gas compression mechanism section (30) due to the shortage of lubricating oil caused by the accumulation and stagnation of lubricating oil and liquefied refrigerant in the space at the bottom of a suction chamber (11).
The electrically driven gas compressor (1) is provided with: an electric motor (20) disposed within the suction chamber (11) of the housing (2); the gas compression mechanism section (30) disposed within the housing (2) and operated by the electric motor (20); a sucked refrigerant guide path (60) for guiding to the gas compression mechanism section (30) a refrigerant within the suction chamber (11); and a lubricating oil supply path (65) for connecting, at the bottom of the suction chamber (11), the suction chamber (11) and the sucked refrigerant guide path (60) in order to supply lubricating oil, which is accumulated and stagnated in the space at the bottom of the suction chamber (11), to the inside of the sucked refrigerant guide path (60). The lubricating oil accumulated in the space at the bottom of the suction chamber (11) is supplied to the inside of the sucked refrigerant guide path (60) by the weight of the oil itself, that is, the lubricating oil can be supplied independent of the rotational speed.
