[0025] When testing in an oily environment, oil mist will be generated. In order to avoid the influence of oil mist on the test accuracy, a hood 15 is provided outside the test component; an oil mist collecting device is provided on the hood 15; the oil mist collecting device is connected to the inside of the hood 15 and is used to collect the oil mist generated by the test in the hood; the oil mist collecting device includes a shell 16, a fixed bracket 17, an air inlet 18, an air outlet 19, a motor 20 with a wind wheel, an oil mist collector 21 and an oil pipeline; the fixed bracket 17 is arranged below the shell; the fixed bracket 1 7 is connected and fixed to the hood 15; the air inlet 18 and the air outlet 19 are arranged on the shell; the air inlet 18 is connected to the hood 15 through a pipeline (not shown in the figure) and communicates with the inside of the hood 15; the motor 20 with the wind wheel is arranged in the shell 16; the oil mist collector 21 is arranged at the rear of the motor 20 with the wind wheel; a second filter 22 is arranged in the oil mist collector 21; the oil mist collector 21 is connected to the oil collection component through an oil pipeline (not shown in the figure), more precisely, connected to the oil tank 12.
