In some embodiments, a temperature-controlled switch 400 is provided in the sixth conduit 6, which can be triggered by the low-temperature cooling oil. It should be noted that, as known to those skilled in the art, the viscosity of the cooling oil is large at low temperature, that is, the oil pressure is large, and as the oil temperature of the cooling oil is continuously increased, the viscosity of the cooling oil is gradually decreased, and the oil pressure is also decreased accordingly.
It can be understood that, when the air compressor is just started, the temperature of the cooling oil in the gear box is lower, and the temperature of the high-pressure head assembly and the low-pressure head assembly is also lower, so that the temperature of the cooling oil which cools the high-pressure head assembly and the low-pressure head assembly is also lower, that is, the cooling oil which flows through the sixth pipeline 6 from the fourth pipeline 4 is low-temperature cooling oil, and because the viscosity of the low-temperature cooling oil is high and the oil pressure is high, the low-temperature cooling oil pushes and triggers the temperature control switch 400 in the sixth pipeline 6, so that the low-temperature cooling oil is discharged to and from the sixth pipeline 6. And after air compressor machine is transporting a period, the cooling oil temperature in the gear box risees gradually, and high temperature cooling oil's viscidity is little, and oil hydraulic pressure is little to lead to it to promote above-mentioned temperature detect switch 400 of triggering for high temperature cooling oil all need get into through fourth pipeline 4 and cool off in the external oil cooler just can get back to in the box 100, continue to carry out the oil circuit circulation after filtering through oil filter assembly 200.

It will be appreciated that the cooling oil filtered by the oil filter assembly 200 will flow through the above-mentioned eighth conduit 8 to the bearing gear set of the high pressure head assembly and through the ninth conduit 9 to the bearing gear set of the low pressure head assembly. Wherein, as shown in fig. 4, above-mentioned eighth pipeline 8 is including two pipelines of looks perpendicular setting, and this application does not do specifically and restricts eighth pipeline 8 and ninth pipeline 9's setting mode, can be convenient for high pressure head assembly's bearing gear train and low pressure head assembly's bearing gear train lubricate can. Further, the cooling oil in the eighth pipeline 8 flows into the head clamping shell of the high-pressure head assembly, the cooling oil is guided by the channel in the head clamping shell to lubricate the bearing gear set of the high-pressure head assembly, and the process of lubricating the bearing gear set of the low-pressure head assembly by the ninth pipeline is the same as the above. Then, the cooling oil lubricated for the bearing gear set is discharged through the head assembly and falls back into the tank 100 to be circulated.
It is further understood that when the air compressor just started, the temperature of the cooling oil in the gear box is lower, low-temperature cooling oil can trigger the temperature control switch 400 in the sixth pipeline 6, so that the cooling oil can flow to the seventh pipeline 7, and flow to the oil filter assembly 200 through the seventh pipeline 7, and lubricate and cool the bearing gear set of the high-pressure head assembly and the bearing gear set of the low-pressure head assembly through the eighth pipeline 8 and the ninth pipeline 9 respectively after being filtered by the oil filter assembly 200, it can be seen that the bearing gear set of the high-pressure head assembly and the bearing gear set of the low-pressure head assembly can be lubricated in time when the air compressor just starts up through the arrangement of the temperature control switch 400, so that the bearing gear set of the high-pressure head assembly and the bearing gear set of the low-pressure head assembly are effectively protected, and the service life of.
