Abstract

The invention relates to the technical field of single-screw pumps, and discloses a single-screw stirring pump. The single-screw stirring pump comprises a single-screw pump body. The bottom of the single-screw pump body is fixedly connected with a pump body base, and the bottom of the pump body base is placed at the top of a positioning seat. The bottom of the positioning seat is fixedly connectedwith a telescopic rod, and the bottom of the telescopic rod is fixedly connected with a supporting plate. The outer surface of the telescopic rod is sleeved with a spring, and the bottom of the supporting plate is fixedly connected with a deeply-buried rod. According to the single-screw stirring pump, the deeply-buried rod is deeply pressed into the ground, thus the supporting plate makes contactwith the ground, and the single-screw pump body is supported; the area of the supporting plate is two times that of the pump body base, thus the contact area of the supporting plate with the ground is increased, and sinking is prevented; and through arrangement of the deeply-buried rod, limiting for the supporting plate is facilitated, stability of the pump body base is improved, the single-screwpump body is prevented from moving due to working vibration, and thus stability during petroleum pumping is improved.

Description

technical field [0001] The invention relates to the technical field of single-screw pumps, in particular to a stirring single-screw pump. Background technique [0002] The single screw pump belongs to the rotor type positive displacement pump. It relies on the meshing of the screw and the bush to produce volume changes in the suction chamber and the discharge chamber to deliver the liquid. It is a closed screw pump with internal meshing. The main working parts are composed of double It consists of the bushing of the head helical cavity and the single helical screw engaged with it in the stator cavity. [0003] In the process of oil extraction, single-screw pumps are needed to extract oil, but most of the oil exists in undeveloped areas, some places are wet and humid, and the size of the current single-screw pump base is fixed and flat, for relatively wet areas In terms of land, the vibration force generated during the working process of the single-screw pump can easily caus...
