Title:
LOCOMOTIVE, AND COMPRESSOR OIL TEMPERATURE CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/045383
Kind Code:
A1
Abstract:
A compressor oil temperature control system, comprising at least one set of heat dissipation devices that are connected in an end-to-end manner, wherein the heat dissipation devices located at the head and tail ends are connected to an oil output port and an oil return port of a compressor, respectively; any one of the sets of heat dissipation devices comprises a radiator (4), a reversing valve, and a primary heat dissipation pipeline and a secondary heat dissipation pipeline that are connected to two output ports of the reversing valve respectively, and the primary heat dissipation pipeline and the secondary heat dissipation pipeline are arranged inside and outside the radiator (4) respectively; when the current oil temperature at the oil output port exceeds a pre-set oil temperature, the reversing valve is switched to a first position, and oil flowing from an input port of the reversing valve into the primary heat dissipation pipeline relies on the radiator (4) for heat dissipation; and when the current oil temperature at the oil output port does not exceed the pre-set oil temperature, the reversing valve is switched to a second position, and the oil flowing from the input port of the reversing valve into the secondary heat dissipation pipeline relies on cold air for heat dissipation. Further disclosed are a method for implementing the control system, and a locomotive comprising the control system. The oil temperature at the oil return port is adjusted by each heat dissipation device to avoid emulsification of oil due to an excessively large temperature difference between the oil return port and the compressor, thereby facilitating prolonging the service life of the compressor.
