At present, the oil pumper that is used for artificial lift is based on beam pumping unit, according to different conventional type beam pumping unit, prefix type beam pumping unit, out-phase type beam pumping unit and the two horse head type beam pumping units etc. of being divided into of horse head and crank quadric chain.These beam pumping units are celebrated with its reliability height, but its transmission of power is through motor-belt pulley-belt-belt pulley-secondary (three grades) reduction box-double-crank-double link-crossbeam axle-walking beam-horse head-polished rod eye, the transmission of power circuit is long, and loss is big, and the complete machine mechanical efficiency is low.
Also had the flexible transmission oil pumping machine of single crank using in recent years, it is to drive the single crank rotation by motor drives planet cycloid gear reduction unit, and the eccentric arbor wheel on the crank drives chain and does stretching motion, drags polished rod eye and moves back and forth.This new pumping unit has shortened the transmission of power circuit, improved mechanical efficiency, but there are two big problems in it: the one, chain is a moving component, with driving wheel, directive wheel, follower except that rolling friction is arranged, also have sliding friction, but because it is open mounting means, can be subjected to the erosion of sleet dust storm, the friction of motion surface has impurity such as sand and dust, greasy dirt, and moving surface can form abrasive wear, quicken the wearing and tearing of critical components such as chain, drive, reduce application life.The 2nd, chain is a flexible connecting member, can only single load bearing, so counterweights such as balance weight can only be less than or equal to static polished rod load, make that complete machine load strengthens when promoting, and each strength of parts has been proposed requirements at the higher level, also increased energy consumption.
The utility model content:
In use the transmission of power circuit is long in order to solve oil pumper, and loss is big, the problem that the complete machine mechanical efficiency is low, the utility model provides a kind of single crank beam pumping unit, this oil pumper has shortened the transmission of power circuit, has reduced frictional dissipation, has improved the mechanical efficiency of complete machine greatly.
The technical solution of the utility model is: this single crank beam pumping unit comprises support, balance weight, control system and base, control system and support are installed on the base, but control system output control signal is given the speed governing braking motor, but the speed governing braking motor directly drives on the output shaft of planet cycloid gear reduction unit rotation and planet cycloid gear reduction unit and by shaft coupling and bearing support a crank is installed, crank is connected with the lower end of connecting rod, the upper end of connecting rod is connected with walking beam, crank drivening rod and balance weight move back and forth, the walking beam rear end is provided with counterweight, and connecting rod drives counterweight, walking beam and horse head move back and forth.
Above-mentioned said walking beam rear end is provided with two counterweights, and the material of counterweight is mixed by nonmetal; Balance weight is by metal and nonmetal designing.
The utlity model has following beneficial effect: 1, owing to adopt the beam type structure, all friction of motion parts all are in sealing, lubricating status, can guarantee that its reliability is identical with traditional beam pumping unit; 2, because the employing motor directly drives the planet cycloid gear reduction unit, and use single crank, single bar-link drive, shortened the transmission of power circuit, reduced frictional dissipation; 3, owing to adopt the counterweight that is provided with the down eccentric barbell structure in the walking beam rear end, improve the balance of well pumping unit state, reduced the weight and volume of balance weight; 4, select nonmetals for use owing on the counterweight material, on balance weight, selected the composite construction of metal and nonmetals for use, thereby reduced manufacturing cost greatly, reduced one-time investment; 5, control system can be provided with each stage motor speed according to arts demand according to the control program of extraction technics institution, reduces oil pumper and starts rotating speed, improves detent torque, has reduced the configuration power of electric motor.But 6, select the brake motor that arrestment mechanism directly is installed in motor interior for use, belong to the power-off brake mode, complete machine structure is simple, dependable performance.
