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 can be called a pumping unit measuring cup. The utility model with the publication number of CN205679290U discloses a measuring cup of an oil pumping unit, which comprises a measuring cup body with openings at two ends, an upper end cover, a lower end cover and a central tube, wherein the upper end cover is covered on one end of the measuring cup body, the lower end cover is covered on the other end of the measuring cup body, the central tube is arranged on the upper end cover, the measuring cup body and the lower end cover in a penetrating way, and the axis of the central tube and the axis of the measuring cup body are positioned on the same straight line; an oil hole is formed in the pipe wall of the central pipe, which is close to the lower end cover, and the oil hole is positioned in the measuring cup body; one end of the central tube is provided with a vacuum generator and an oil pumping connecting tube.
Disclosure of Invention
For overcoming the deficiencies in the prior art, the utility model aims to provide a pneumatic sealing structure of the balance gas pipe of the pumping waste oil machine.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: a sealing structure of a balance air pipe of a pneumatic pumping and connecting waste oil machine is characterized in that a measuring cup of the pneumatic pumping and connecting waste oil machine comprises a measuring cup body with two open ends, an upper end cover, a lower end cover and a central pipe; the lower end cover is provided with an opening, and the opening extends towards one side to form a folded edge; the outer edge surface of the folded edge is provided with threads, a balance air pipe is inserted into the opening, and the opening is sleeved with a locking nut; and a sealing ring is arranged between the locking nut and the lower end cover, one end of the balance air pipe is positioned in a measuring cup body of the pneumatic pumping waste oil machine, and the other end of the balance air pipe is communicated with a tank body of the pneumatic pumping waste oil machine.
The preferable technical scheme is as follows: the distance between the top of the balance air pipe and the upper end cover is 3-10 cm.
The preferable technical scheme is as follows: one side of the opening outside the cup body of the vector cup extends to form a folded edge.
Because of the application of the technical scheme, compared with the prior art, the utility model the advantage that has is:
the utility model discloses a set up balanced trachea in the graduated flask cup, make atmospheric pressure in the graduated flask equal with jar internal atmospheric pressure, when opening vacuum generator and take out and connect waste oil, the total volume of vacuum is jar body does not have the sum of the volume of oily part and the volume of the non-oily part of graduated flask cup, consequently, the fluctuation of the volume of oil feed diminishes the influence of the total volume of vacuum, and balanced tracheal mounting means has sealed effectual advantage.
