The technical solution of the utility model is:
A kind of compressor oil-supplying system that forces fuel feeding and pressure reduction auxiliary feed-oil to combine, it comprises oil pump, screw down nonreturn valve, the damping one-way valve, pressure transducer and controller, the inlet of described oil pump links to each other by the outlet of pipeline with compressor oil cooling device, the outlet of oil pump links to each other with the corresponding oil-feed port of compressor, screw down nonreturn valve is attempted by the two ends of oil pump, the inlet of screw down nonreturn valve links to each other with the inlet of oil pump, the outlet of screw down nonreturn valve links to each other with the outlet of oil pump, the outlet of oil supply system oil cooler links to each other with the corresponding oil-feed port of compressor by the damping one-way valve, each induced signal input end of pressure transducer links to each other with the corresponding pressure signal output part of compressor oil-supplying system, each signal output part of pressure transducer links to each other with the respective signal input end of controller, and the signal output part of controller links to each other with the control signal input end of oil pump.
Oil supply system of the present utility model also comprises oil strainer, and the inlet of described oil strainer links to each other with the outlet of compressor oil cooling device, and the outlet of oil strainer links to each other with the inlet of oil pump.
Pressure transducer of the present utility model is three, is respectively inspiratory pressure sensor, back pressure transducer and oil pressure sensor.
The beneficial effects of the utility model:
The utility model will force the advantage of fuel feeding and pressure reduction oil supply system effectively to combine, guarantee that compressor moves reliably can before pressure reduction is not set up, for the enough fuel feeding of compressor, also can after pressure reduction is set up, only depend on suction and discharge pressure reduction fuel feeding.This fuel system is in the selection of oil pump, and oil pump flow is littler than the oil pump flow of forcing fuel system to be selected.Reduce product cost and also saved electric energy, but also avoided only depending on the increase and decrease of pressure reduction fuel feeding energy to carry the insensitive shortcoming of reaction.
