The invention provides an oil pumping unit which is switched to a third air port to be communicated with a second air port when oil in a second tank body needs to be discharged, an external air source is used for filling the second tank body, and the oil in the second tank body is pressed out of a system through an oil discharge port to finish oil discharge.
The first tank body is provided with a vacuum generator. The utility model discloses a utility model patent that grant publication number is CN205679290U discloses a beam-pumping unit graduated flask, and vacuum generator and oil pumping connecting pipe all set up in the casing, and vacuum generator includes air nozzle, gas vent and vacuum sunction inlet usually, and wherein the lateral wall of casing is all worn out to air nozzle and gas vent to can be fixed with it through threaded connection, the vacuum sunction inlet stretches into in the center tube, and hollow generator can pass through oilhole and graduated flask cup intercommunication, with its evacuation. One end of the oil pumping connecting pipe penetrates through the shell and is in threaded connection with the three-way pipe, the other end of the oil pumping connecting pipe extends into the central pipe, and the pipe wall of the oil pumping connecting pipe and the shell can be fixedly connected through threads; the second end of the three-way pipe is provided with a vacuum meter, and the third end of the three-way pipe is communicated with an oil pumping pipe. The oil pumping pipe can flow into the measuring cup body through the oil hole after pumping oil, and the vacuum meter can be used for detecting the vacuum degree in the measuring cup. The high-speed air flow of evacuation can produce the noise when flowing through the gas vent, therefore, it is necessary to design a kind of pneumatic suction and connect the silencing structure of the waste oil engine.

Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve.
