The invention provides a pneumatic vortex self-priming lubricating and cooling
system in the technical field of devices utilizing
compressed air as power. The pneumatic vortex self-priming lubricating and cooling
system comprises an
oil tank, a vacuum generator, a vortex separator and an air and liquid
nozzle, wherein the vacuum generator comprises an input end and an output end, a
cold air cavity, a vacuum
nozzle, a
cold air jet cavity, a jet vacuum cavity and an air-liquid mixing cavity are sequentially arranged between the input end and the output end, the
cold air jet cavity is a
conical cavity, the vacuum
nozzle is provided with an oil injection
pipe and a plurality of air flow holes, the oil injection
pipe is arranged at the center of the vacuum nozzle, the air flow holes are uniformly arranged around the oil injection
pipe, and the oil injection pipe is communicated with the
oil tank; the vortex separator is provided with a
compressed air input port, a hot air output port and a cold air output port, the cold air output port is communicated with the input end of the vacuum generator, and the air and liquid nozzle is communicated with the output end of the vacuum generator. The pneumatic vortex self-priming lubricating and cooling
system takes the air as power, realizes vacuum liquid suction, air-liquid mixing and atomizing, heating for preventing freezing and plugging, so that workpieces and a tool can be sufficiently lubricated and cooled.
