Sealing and isolating type bidirectional oil extraction pump

Abstract

The invention discloses a sealing and isolating type bidirectional oil extraction pump which comprises equipment shell. A traction cavity is formed in the equipment shell. A rotating disc is installedon the inner wall of the rear side of the traction cavity in a rotating fit manner. A protruding block is fixedly arranged on the end face of the front side of the rotating disc. The protruding blockis provided with a connecting rod in a rotating fit manner. A sliding groove is formed in the left side of the traction cavity in a communicating manner. A sliding block is arranged in the sliding groove in a sliding fit manner. The sliding block and the left end of the connecting rod are matched in a rotating manner. The left side of the sliding groove is provided with a first transmission cavity in a communicating manner. A first traction wheel and a second traction wheel are installed between the front inner wall and the rear inner wall of the first transmission cavity in a rotating fit manner. The second traction wheel is located right below the first traction wheel. A first traction line is wound around the periphery of the first traction wheel. The upper end of the first traction line and the left end face of the sliding block are fixedly connected. The first traction line is wound around the periphery of the second traction wheel. A sliding cavity is formed in the right side wall of the lower portion of the first transmission cavity in a communicating manner.

Description

technical field [0001] The invention relates to the field of energy exploitation, in particular to an isolated bidirectional oil production pump. Background technique [0002] When traditional oil production equipment is operating, it often faces the problem that it can only do work once in a stroke, which leads to low efficiency, high energy consumption, and poor economy of traditional equipment, and it cannot make good use of simple mechanical structures to achieve various production operations. , is a major bottleneck in the development of energy engineering, so there is an urgent need for a light-weight, easy-to-operate oil production pump that can perform work multiple times within the stroke, thereby simplifying costs, improving economical and power requirements, and meeting the needs of the energy mining industry. need. Contents of the invention [0003] The object of the present invention is to provide an isolated bidirectional oil recovery pump, which can overcom...
