Abstract

The invention provides a filler removing tool of a single-screw pump, and belongs to the technical field of petroleum tools. The filler removing tool of the single-screw pump is characterized in that one end of a first knife edge is connected with a rod body; the other end of the rod body is connected with a handle, wherein the rod body is bent; the first knife edge is in a shape of a circular hook point; the rod body is bent in 120 degrees; the connecting is performed by a welding manner. The filler removing tool of the single-screw pump has the advantages that the design is implemented for the wearing, deforming, gumming and other circumstances of the filler of the single-screw pump; a worker on site can selectively use according to the degree of wear of the filler. The filler removing tool is flexible, easy to be used, and simple to operate, and can quickly remove old filler with a little force; a good safe operating environment is provided to an operator; a lot of time for operating can be saved during operating, and therefore, the labor intensity of the worker is obviously reduced, the sealing cycle of the single-screw pump is prolonged, and the normal running of the single-screw pump is ensured.

Description

technical field [0001] The invention relates to a single-screw pump stuffing removal tool, which belongs to the technical field of petroleum tools. Background technique [0002] In the heavy oil production process, the single screw pump is an important conveying equipment in the oil production metering station. Whether the single screw pump is normal and whether the large tank of crude oil can be transported smoothly depends on the single screw pump. With the prolongation of the service life of the single-screw pump on site, crude oil leakage is often caused by serious wear of the single-screw packing seal. In the process of replacing the single-screw packing, there is a narrow space for on-site operation, it is difficult to remove the old packing with common tools (screws), and the operation time of the staff is long, time-consuming and labor-intensive, etc. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention ...
