Abstract

The invention discloses a hanger with multiple sealing sections and manufacturing equipment thereof. The hanger comprises a first motor arranged on a bottom plate, wherein an electric chuck is arranged on the first motor, a storage unit is arranged on the bottom plate, an outlet and an inlet are formed in the storage unit, and the outlet is located above the electric chuck; a lifting unit is further arranged on the bottom plate, a clamping unit is arranged at the lifting end of the lifting unit, a turning tool is rotationally arranged on the clamping unit, the turning tool corresponds to the outer wall of a hanger blank, and the clamping unit controls the machining depth of the turning tool through a transmission unit; and the outlet and the electric chuck are both located on the lifting stroke of the clamping end of the clamping unit. According to the hanger, a limiting boss, an annular groove and an annular sealing groove of the outer wall of the hanger blank can be machined through the turning tool, the hanger blank can be clamped through the clamping unit for feeding, a sealing ring can be installed on the machined annular sealing groove through a sealing ring installation unit, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of hangers, in particular to a hanger with multiple sealing sections and manufacturing equipment thereof. Background technique [0002] Oil production engineering is the general term for various engineering and technical measures taken to the reservoir through production wells and injection wells according to the development objectives in the process of oilfield production. The tubing hanger is a device that supports the tubing string and seals the annular space between the tubing and the casing. . The existing hanger manufacturing equipment separates the clamping device and the turning tool, and needs to separately set the power to control the clamping device and the power to control the turning tool, and the cost is high and the structure is relatively complicated. Contents of the invention [0003] An object of the present invention is to provide a hanger with multiple sealing sections for the multi-section seal...
