Description

Technical Field

[0001] The utility model belongs to the field of oil pumping devices, in particular to a barrel-type oil pumping device used for pumping oil from an oil tank. Background Art

[0002] Oil tanker trucks are also called mobile refueling trucks, computer tax-controlled refueling trucks, oil tank trucks, oil loading trucks, oil transport trucks, oil pulling trucks, oil transport trucks, and edible oil transport trucks. They are mainly used for the transportation and storage of petroleum derivatives (gasoline, diesel, crude oil, lubricating oil, coal tar and other oil products). Oil tanker trucks may be overloaded during the filling process, so some of the oil in the tanker truck needs to be pumped out. However, the existing technical methods generally use an air pump to extract the excess oil, which is too costly. On the other hand, the operation is difficult and inconvenient for staff to use.

[0003] Therefore, those skilled in the art provide a barrel-type oil pumping device for pumping oil from an oil tank to solve the problems raised in the above-mentioned background technology. Utility Model Content
