Problems solved by technology
When the pumping unit is working normally, the hot water circulation hose 12, together with the wellhead tee joint 13, moves up and down periodically under the swing of the donkey head of the pumping unit, causing the hot water circulation hose 12 to be on the support beam of the pumping unit. Periodic friction on 14 for a long time, after 6-12 months of continuous work the hot water circulation hose 12 will be damaged and leak and will have to be replaced

The invention discloses a hot water circulation hose pup joint and an oil pumping unit. The hot water circulation hose pup joint comprises a first pipe connector (1), a main body pipe (3), a piston pipe (4) and a second pipe connector (7) which are sequentially connected in a sealed mode, an elastic part (5) is connected between the main body pipe (3) and the piston pipe (4), the piston pipe (4) can move in the axis direction of the main body pipe (3), and the elastic part (5) can provide restoring force for the piston pipe (4). The hot water circulation hose pup joint is used for replacing a hot water circulation hose to be in direct contact with a pumping unit support, the service life of the hot water circulation hose is prolonged, maintenance time is shortened, and cost is saved.
Description
technical field [0001] The invention relates to the technical field of adopting equipment, in particular to a hot water circulation hose short connector, or a pumping unit including the hot water circulation hose short connector. Background technique [0002] In the oil field production process, in order to maintain normal production in high pour point oil blocks and heavy oil blocks, closed double hollow rod hot water circulation heat tracing technology is usually used to achieve the purpose of wax prevention and viscosity reduction. This technology uses demineralized water as a carrier, heats it through the ground water jacket furnace, injects it into the high-vacuum heat-insulated inner pipe, and returns to the inner and outer rod annulus through the end of the hollow rod. The rod is passed to the produced fluid of the oil layer to increase the temperature of the produced fluid. [0003] In practical application, the circulating water surface pipeline 11 is connected to ...
