Description

TECHNICAL FIELD

[0001] The utility model relates to underground rod type pump technical field, concretely is a kind of multifunctional underground rod type pump. BACKGROUND

[0002] The working principle of the multifunctional underground rod type pump is based on the principle of suction. When the surface pumping unit moves the downhole sucker rod up and down through the pull rod, the piston in the pump body also moves up and down. The up-and-down movement of the piston causes the pressure in the pump body to change, thereby controlling the opening and closing of the traveling valve and the fixed valve. When the piston moves upward, the pressure in the pump body decreases, the traveling valve opens, and the liquid in the well is sucked into the pump body; when the piston moves downward, the pressure in the pump body increases, the fixed valve opens, and the liquid in the pump body is discharged into the oil pipe.

[0003] In related technology, impurities and dirt can accumulate in the piston during long-term use of oil pumping. These impurities and dirt can hinder the normal movement of the piston, resulting in reduced efficiency of the equipment. Moreover, impurities suspended in the oil (such as sand, particulate matter, etc.) can enter the interior of the piston, accumulate between the plunger and the cylinder, and cause the plunger to be obstructed, resulting in a decrease in oil quality and affecting subsequent processing and use.
