Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art without creative labor belong to the scope of protection of the utility model.

[0023] Please refer to Figures 1-5 The utility model provides an embodiment: an automatic exhaust device of air compressor oil system, including base body 1 and base auxiliary body 2, one side of base body 1 is connected through base connecting nut 3 screw thread connection base auxiliary body 2, the upper and lower sides of base body 1 and base auxiliary body 2 are connected through cover nut 8 screw thread connection upper cover plate 4 and lower cover plate 6, the upper end surface of upper cover plate 4 is fixedly connected air inlet 5, the lower end surface of lower cover plate 6 is fixedly connected exhaust port 7.

[0024] Further, the base body 1 includes an exhaust pipe 101, an exhaust chamber 102, an impeller 103, a valve chamber 104 and a one-way valve 105. The exhaust pipe 101 penetrates the air inlet 5 and the exhaust port 7. The middle part of the exhaust pipe 101 penetrates the exhaust chamber 102. The exhaust chamber 102 is cylindrical. The impeller 103 is rotatably connected to the exhaust chamber 102 by a rotating shaft. The lower part of the exhaust pipe 101 is connected to the valve chamber 104. The one-way valve 105 is sleeved in the valve chamber 104. The oil path can be controlled.

[0025] Further, the impeller 103 is made of copper, and the blades of the impeller 103 are located in the vertical direction of the exhaust pipe 101.

[0026] Further, the air inlet 5 and the inner side of the valve cavity 104 are provided with sealing pads, which enhances the sealing effect of the equipment.

[0027] Further, the base body 1, the base auxiliary body 2, the upper cover plate 4 and the lower cover plate 6 are made of acrylic, so that the running state of the equipment can be directly observed, and the function of an observation window is achieved.

[0028] Working principle: first start the auxiliary oil pump, the auxiliary oil pump runs will inject oil into the chamber of the main oil pump, in this process, the air in the chamber is discharged back to the oil tank through the exhaust pipe, at this time, the operator can observe the window of the acrylic plate of the exhaust device and the impeller rotation indicator, and real-time monitor the flow of the lubricating oil, including the flow direction and whether it contains bubbles, so as to determine whether the main oil pump has the starting condition and whether it can normally bear the load after running.

[0029] When it is observed that the lubricating oil flows continuously and the bubbles are significantly reduced, the air compressor needs to be started after the system oil temperature and oil pressure reach the normal range. After the air compressor is started, the main shaft drives the main oil pump to run, and the main oil pump starts to extract lubricating oil from the oil tank after the main oil pump is started, and the lubricating oil is delivered to the lubricating part of the equipment after being pressurized. At this time, the negative pressure formed in the exhaust device will automatically suck up the spherical check valve body, closing the exhaust passage. The automatic locking design replaces the traditional manual valve operation, effectively avoids the gas-containing lubricating oil entering the tubular heat exchanger, eliminates the heat exchange efficiency and the risk of cavitation, and ensures the success rate of the first start of the air compressor.
