Technical Field
[0001] The present application relates to the technical field of air compressors, and in particular to a stabilizing structure of an oil drain port of an air compressor. Background Art
[0002] Air compressors require oil for sealing and cooling during the compression process, and also require oil for lubrication. Therefore, most of the current screw air compressors are oil-injected and require air compressor oil. After the air compressor oil has been used for a period of time, the oil needs to be replaced.
[0003] The existing air compressor discharges oil through an oil drain pipe, which is usually arranged vertically or horizontally. When discharging oil, a collecting tank is placed under the oil drain pipe to collect the waste oil. However, when the horizontal oil drain pipe starts to discharge oil, the internal pressure of the air compressor is high, the waste oil is discharged over a long horizontal distance, the waste oil is easily sprayed onto the ground, the collecting tank cannot play a good collection role, and the oil discharge stability of the oil drain port needs to be improved. Therefore, a technical measure is proposed to solve the problem that the waste oil is easily sprayed onto the ground, the collecting tank cannot play a good collection role, and the oil discharge stability of the oil drain port needs to be improved under the existing technology.
