Abstract

The invention relates to a traveling barrel sand discharging subsurface pump, wherein, bipolar cylinder bodies are connected on the same axial lead in series, two ends of the cylinder bodies which are connected into a group in series are respectively provided with reversing clapper groups, chambers of shells of the reversing clapper groups are elastically connected with the other ends of contact terminals, slide blocks operate in the chambers, which are communicated with pipelines, sealing elements are arranged on the contact terminals and the slide blocks. The invention reduces the cost, improves the leak tightness, security and reliability.

Description

technical field [0001] The invention relates to an oil well pump, in particular to a moving barrel sand discharge oil well pump. Background technique [0002] At present, there are precedents at home and abroad for using compressed air or liquid as power to increase the mechanical device for conveying fluid medium through a cylinder or liquid cylinder with two poles connected in series. However, under different usage conditions, the medium to be pressurized and conveyed has a different allowable range of pressure difference at the inlet. During the pressurized conveying process, when the pressure at the inlet exceeds the allowable range, insufficient material supply or displacement Insufficient and other abnormal phenomena, resulting in insufficient displacement when selecting booster equipment specifications, or excessively low front-end pressure due to excessive suction, thus affecting the normal operation of the entire pipe network. [0003] In addition, the moving barre...
