Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] like Figure 1~3 Shown, a kind of pumping unit provided by the present invention comprises

[0037] The first tank body 1 has a first opening 11;

[0038] The second tank body 2 has a second port 21 and an oil discharge port 22; and

[0039] Reversing valve 3;

[0040] Wherein, the reversing valve 3 includes a first air port 31 communicating with the first port 11, a second air port 32 communicating with the second port 21, and a third air port 33 for communicating with an external air source,

[0041] When the third air port 33 is not connected to an external air source, the first air port 31 and the second air port 32 remain connected,

[0042] When the third air port 33 is connected to an external air source, the third air port 33 is kept in communication with the second air port 32 and the first air port 31 is kept closed.

[0043] The present...

Abstract

The invention provides an oil pumping unit, which comprises a first tank with a first opening, a second tank with a second opening and an oil drain port, and a reversing valve. The reversing valve comprises a first gas port in communication with the first opening, a second gas port in communication with the second opening, and a third gas port in communication with an external gas source. When no external gas source is connected with the third gas port, the first gas port and the second gas port are kept in communication with each other. When the external gas source is connected with the third gas port, the third gas port and the second gas port are kept in communication with each other. By means of the oil pumping unit, when the oil in the second tank needs to be discharged, the third gas port and the second gas port are switched to be in communication with each other. In this way, the gas of the external gas source is filled into the second tank, and then the oil in the second tank is discharged to the outside via the oil drain port. As a result, the oil discharge is completed.

Description

technical field [0001] The invention relates to the field of pumping units, in particular to a pneumatic pumping unit. Background technique [0002] At present, the structure of the pumping unit is poor and complicated, and the operation is inconvenient. Especially in the process of oil discharge, it is easy to leak and close the key valve, which will cause adverse effects on the device. Contents of the invention [0003] The object of the present invention is to provide an oil pump unit that solves one or more of the above-mentioned problems in the prior art. [0004] A kind of pumping unit provided by the present invention comprises [0005] The first tank body is opened with a first mouth; [0006] a second tank body having a second port and an oil discharge port; and [0007] reversing valve; [0008] Wherein, the reversing valve includes a first air port connected to the first port, a second air port connected to the second port and a third air port used to commun...
