Vacuum oil pumping buffer tank

The invention relates to a vacuum oil pumping buffer tank. The vacuum oil pumping buffer tank comprises a buffer tank body, an extraction opening and an oil inlet are arranged in the upper portion of the buffer tank body, and an oil drain valve is arranged on the lower portion of the buffer tank body. The vacuum oil pumping buffer tank not only can be used as an oil pumping buffer tank of a transformer, but also can be used as a sediment and storage container for transformer oil. The vacuum oil pumping buffer tank has the advantages that 1, the vacuum oil pumping buffer tank is reasonable in structural design, convenient to use, safe and reliable, not only can be used as the oil pumping buffer tank of the transformer, but also can be used as the sediment and storage container for transformer oil; 2, an oil pipe and an oil baffle are arranged so that sucked transformer oil can be effectively prevented from entering the extraction opening and damaging a vacuum pump; 3, a higher support and a lower support are arranged, so that the buffer tank body is arranged aslant, and oil drainage and washing are convenient; 4, workers can conveniently know the storage amount of transformer oil in the tank body through an oil level indicator on the lateral wall of the buffer tank body.
