Two, background technology
At home and abroad in the petroleum production engineering of oil field, mechanical oil recovery equip ment commonly used is a beam pumping unit at present.Beam pumping unit because simple in structure, use reliably, make it in oil extraction process, obtain using widely, what still adopted more than 90% in China oil field at present is beam pumping unit.But because its torque factor is bigger than normal, cause the clean torque peak on the crank axle excessive, it is big that energy consumption also becomes thereupon; At heavy crude producing, high coagulate oil, deep-seated oil, particularly during highly aqueous field, use conventional beam-pumping unit can't realize more economical, more effectively exploit.According to the requirement of oil production technology, both at home and abroad all at development long stroke, big load, low jig frequency, energy-efficient oil pumper.Wherein chain drive pumping unit has Windsor, complete machine is in light weight, compact conformation, power consumption is few, jig frequency is low, stroke is long, the suspension point acceleration change is little, inertial load is little, operate steadily, the reducer nominal torque is little and be easy to characteristics such as installation, therefore obtained general development in recent years, but because there is the changement complexity in common chain drive pumping unit, the crosshead shoe position is serious wear in use, fracture accident takes place in path chain and king-pin easily, the balance sysmte complexity, problems such as reliability is on the low side make the application of chain type oil pump be subjected to very big restriction.
Three, summary of the invention
Technical problem to be solved by this invention is to provide a kind of compound head sheave type chain drive pumping unit at the deficiency in the above-mentioned existing chain drive pumping unit technology, its compact conformation, and safe and reliable during work, balance is good, and energy-saving effect is remarkable.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of compound head sheave type chain drive pumping unit, comprise motor, the belt gear that is connected and is driven by it with described motor, be connected the reducer on the output shaft of described belt gear, be connected on the output shaft of described reducer and drive the crank that rotates by this reducer, be connected connecting rod and frame on the crank, being equipped with on the described frame can be for the guide rail of slide block slip, head sheave and lower sprocket fixed mount, described head sheave is provided with steel cable, by steel cable connection cord rod connector and be installed in sucker rod on the described Rope rod connector, it is characterized in that: described slide block and rod hinge connection, the upper end of slide block is connected with chain one end, the lower end of slide block is connected with the other end of chain, described chain is on upper sprocket wheel and lower sprocket and be meshing with each other, described lower sprocket is hinged on the lower sprocket fixed mount, and described upper sprocket wheel is connected with head sheave is coaxial.Motion driving sliding block by connecting rod is slided on guide rail, the chain that is connected on the slide block moves with slide block, engaged transmission by chain and upper sprocket wheel and lower sprocket drives the upper sprocket wheel rotation, and upper sprocket wheel drives head sheave and rotates, and drives sucker rod then and pumps.
Described guide rail is rail plate or rolling guide.
The diameter of described upper sprocket wheel is less than the diameter of head sheave.
Described slide block adopts slide block or roller structure.
The lower end of described slide block is provided with balance weight.
Described lower sprocket fixed mount is provided with oil-way.
The present invention compared with prior art has the following advantages:
1, compact conformation, safe and reliable, the mechanical transmission structure technology maturation that adopts among the present invention realizes easily.
2, balance weight directly is attached on the slide block, makes the balance weight energy stored be used for balanced load completely, and counterbalance effect is fine.
3, adopt big head sheave and minor sprocket, can realize long stroke.
4, energy-efficient.Than common chain drive oil pump energy-saving about 40%; Compare energy-conservation about 15% with energy-saving beam pumping units such as existing pair of horse head oil pumper, down eccentric barbell formula oil pumper, curved beam pumping units.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
