Abstract
The invention discloses a sealing assembly for an oil pumping rod, wherein the sealing assembly comprises sealing rings, a fastening screw rod, nuts and a sealing base, wherein fractures are formed on the sealing rings, and unthreaded holes are arranged at the both sides of the fracture; the sealing base is welded on the oil pumping rod, and unthreaded holes are arranged on the sealing base as well; the fastening screw rod of a U-shaped structural design and is composed of a cross rod, a left screw rod, and a right screw rod; and in installation of the fastening screw rod, the cross rod clings to the sealing rings, the left screw rod and the right screw rod penetrate through the unthreaded holes on the sealing rings and the sealing base respectively, and the terminals of the left screw rod and the right screw rod are fastened by the nuts. The sealing assembly for an oil pumping rod, which is disclosed by the invention, is reasonable in structural design, convenient in installation, and long-lasting in service life; simultaneously, a sealing performance can be adjusted by adjustment on the quantity of the sealing rings in the sealing assembly according to the actual working condition of the oil pumping rod, thus effectively improving the movement performance while guaranteeing the sealing performance of the oil pumping rod.
Description
Technical field
The present invention relates to a kind of sucker rod black box, relate in particular to a kind of sucker rod black box of easy for installation, stable performance, belong to oil accessory technical field.
Background technology
Mechanical oil recovery is the main mode that the oil exploitation industry is recovered the oil.Along with international and domestic oil industry rapid development, the mechanical oil production technology technology has had significant progress, and the supporting level of technical equipment improves constantly, and has formed four kinds of oil recovery forms such as sucker rod pump, water conservancy piston pump, submersible electric pump and air pump.Wherein, sucker rod pumping is to be that master's rod pumping system is realized with sucker rod, oil pumper and oil well pump.Under oil pumper drove, sucker rod drove oil pump plunger piston and pumps, and fluid is evacuated to ground.In sucker rod moves up and down process, can take a certain amount of crude oil out of, cause waste.Therefore, people can be provided with black box on sucker rod, prevent the leakage of crude oil.
Usually, adopt the bigger cooperation of the magnitude of interference with the raising seal degree between sucker rod and the black box, but can cause bigger frictional force, reduce the application life of black box; Simultaneously, the installation of black box is inconvenience comparatively, need sucker rod be dismantled during installation, has influenced the efficient that oil-recovery operations is produced.
Summary of the invention
To the demand; The invention provides a kind of sucker rod black box; The sealing assembly is easy for installation, stable performance, and application life is lasting; People can regulate the sealing performance of black box according to the practical working situation of sucker rod, when guaranteeing the sucker rod sealing performance, effectively improve its exercise performance.
The present invention is a kind of sucker rod black box, and the sealing assembly comprises sealing ring, fastening screw, nut and sealed base, has fracture on the described sealing ring; The fracture both sides are provided with unthreaded hole, and described sealed base is welded on the sucker rod, also offer unthreaded hole on it; Described fastening screw adopts " U " structure design; Be made up of cross bar and left and right screw rod, when described fastening screw was installed, cross bar was close to sealing ring; Left and right screw rod passes the unthreaded hole on sealing ring and the sealed base respectively, and the terminal adopts nut fastening.
In the present invention's one preferred embodiment, the quantity of described sealing ring is 2 at least.
In the present invention's one preferred embodiment, the material of described sealing ring can be NBR, HNBR, EPDM, FLS or PTFE.
In the present invention's one preferred embodiment, the unthreaded hole aperture is about 2-2.5mm on the described sealing ring, is about 4-5mm with the distance of fracture.
The present invention has disclosed a kind of sucker rod black box, and the sealing modular construction is reasonable in design, and is easy for installation, and application life is lasting; Simultaneously, can through regulating the quantity of black box inner seal ring,, when guaranteeing the sucker rod sealing performance, effectively improve its exercise performance according to the practical working situation of sucker rod to realize the adjusting of sealing performance.
