Abstract

The invention relates to an oil pumping unit. The oil pumping unit comprises a horse head, a girder beam, a bracket, high-pressure springs, a cross beam, connecting rods, a crank, a reduction box and a motor. The horse head is fixedly connected with one end of the girder beam to be integrally formed. The middle section of the girder beam is rotationally connected with the top end of the bracket through a rotating shaft. The other end of the girder beam is rotationally connected with a middle protrusion of the cross beam through a rotating shaft. One end of one of the two high-pressure springs is fixedly connected with one end of the girder beam. The other high-pressure spring is fixedly connected with the other end of the girder beam. The other ends of the two high-pressure springs are fixedly connected with protrusions at the top ends of two long plates stretching out of the front side and the back side of the bracket correspondingly. According to the oil pumping unit, the energy utilization rate and production benefits are increased; the loading condition of suspension points can be improved, and the loading condition of the motor is relieved; the balance degree of the oil pumping unit is improved, and inverse torque is eliminated or weakened.

Description

Oil pumper
Technical field
The present invention relates to a kind of oil pumping in oil fields articles for use, particularly oil pumper.
Background technology
Current domestic and international each manufacturer successively develops the oil pumper of the models such as front beam-pumping unit, phased crank oil pumper, air balance oil pumper, overcomes some shortcomings of conventional beam-pumping unit in varying degrees. But still do not break away from and utilize quadric chain that rotary motion is changed into straight reciprocating motion, cause balance of well pumping unit effect and do not obtain basic improvement, acceleration is still significantly high, inertial load is big, the shortcoming that gross mass increases exponentially, hence without solving root problem, and make structure more complicated, to maintenance, maintenance, and both increase certain burden service life.
Current Power Consumption of Pumping Units amount is big, and work efficiency, capacity usage ratio this present situation low is still one of emphasis of China's oil pumper research, efficiency of the pumping unit and energy-conservation in, also have very big room for promotion
And electric motor normal working is often with light running, thus results in oil pumper and mate unreasonable with the load of motor, be in operation and be in the high-power situation with little load. Motor is in meritorious duty when oil pumper is up, is in generating state time descending, and " low load with strong power " phenomenon occurs in the most of the time, and this phenomenon is prevalent in oilfield exploitation. Particularly in the development late stage in oil field, the yield of machine-pumped oil well sharply declines, and " pump is empty " of oil pumper various degrees at work and " dry tap " situation, inefficiency, energy consumption is big, and backlash increases. According to statistics, there are nearly 80,000 beam pumping units in current China, accounts for about the 90% of whole oil pumper market, and the water content of oil well can be gradually increasing, and the quantity of mechanical oil well also may proceed to increase year by year. The average load rate of motor is only 20% one 30%, and section motor rate of load condensate is lower, causes the significant wastage of the energy. In cost for oil production, the oil pumper electricity charge account for about 30%, year power consumption account for the 20%-30% of oil field total power consumption, for the second of oil field power consumption, be only second to water filling. If some energy resource consumptions saved by an oil pumper, then whole economic benefit is quite surprising.
Summary of the invention
Present invention is generally directed to problem above, it is provided that a kind of capacity usage ratio that improves, increase productivity effect, enough improving the load condition of suspension point, alleviate motor load situation, this oil pumper improves balanced degree, eliminating or weaken the oil pumper of the existence bearing torque, its technical scheme adopted is as follows:
Oil pumper includes: caput Equi Asini, trip fine strain of millet, support, high pressure spring, crossbeam, connecting rod, crank, reduction box, motor and brake gear, described caput Equi Asini and the affixed global formation in walking beam one end, walking beam stage casing is rotationally connected by rotating shaft and cantilever tip, the walking beam other end is rotationally connected by rotating shaft and crossbeam intermediate projections, one end of one, two high pressure springs is affixed by one end of affixed mode Yu walking beam, two another roots of high pressure spring are affixed by the other end of affixed mode Yu walking beam, the other end of two high pressure springs by affixed mode respectively with support before and after the two block length plate top projections stretched out of both sides affixed, two connecting rod one end are rotationally connected with the two ends, left and right of crossbeam respectively by rotating shaft, the other end of two connecting rods is rotationally connected by the crank of the mode being rotationally connected and reduction box both sides, two cranks are rotationally connected respectively at the both sides of reduction box, motor is connected with the rotation wheel of reduction box front end by belt.
On technique scheme basis, described crank includes: curved bar and runner, and curved bar is affixed with runner, and two cranks are affixed by rotating shaft.
The beneficial effect that the present invention produces has: improve capacity usage ratio, increases productivity effect, enough improves the load condition of suspension point, alleviates motor load situation, and this oil pumper improves balanced degree, eliminates or weaken the existence of negative torque.
