SYSTEM FOR PRE-START HEATING OF COMPRESSOR ASSEMBLIES OIL IN COMPRESSOR STATION Russian patent published in 2018 - IPC F04D29/58 

FIELD: machine engineering.

SUBSTANCE: system for pre-start heating of oil of compressor assemblies in a compressor station comprises a heat exchange unit installed in an oil tank of each compressor assembly, made in the form of coil of the heat exchanger, and an oil pump connected to oil tank and to oil supply pipe to the compressor friction units and to oil return to the oil tank. The heat exchange unit of each of the compressor assemblies is connected with its inlet and outlet, respectively, with a pressure manifold for supplying oil to the heat exchange units of the compressor assemblies and a return manifold for removing oil from the heat-exchange units of the compressor assembly. In each compressor assembly, the pipe to supply oil to the friction units is also connected to the pressure and return manifold.

EFFECT: invention makes it possible to reduce time for preparation to start and start of backup compressors at compressor station, and substantially reduce operating costs of the electric power at their start.
