Abstract
The utility model relates to a single crank energy-saving type oil pumping unit which is composed of an electric motor (1), a belt drive (2), a chain drive (3), a reversing mechanism of a crank rocker, a roller extended range mechanism, a counterweight (10) and a pumping rod (9). The utility model has the characteristics that the electric motor (1) is arranged on a base (12), other drive systems are evenly arranged on a supporting frame (11), wherein, the supporting frame (11) can be backwards inclined or be laid down, and thus, the transporting, the installation and the workover treatment, etc., of the pumping unit are simple, safe and convenience. Meanwhile, because a head sheave is directly balanced, the utility model has a good balance effect, enlarges the lifting capacity of the pumping unit, reduces power consumption, and reduces oil extraction cost.
Description
The single crank energy-saving beam pumping unit that the utility model relates to belongs to a kind of ground installation that no slide beam mechanical oil recovery is used.
Pumping unit is one of main ground installation of suction crude oil, the ground machine oil production equipment that the our times various countries adopt, beam pumping unit and no beam pumping unit are arranged, the head sheave long stroke pumping unit of its Chinese patent ZL95200356.2, can realize the direct balance of head sheave, good balance effect, increased the lifting capacity of pumping unit, reduced power consumpiton, reduced cost for oil production, but Duoed a roller bearing travel prolongation mechanism than the common beam machine on its structure, when small-sized pumping unit did not need long stroke, it is a bit complicated that this scheme just seems.
The purpose of this utility model is that head sheave long stroke pumping unit is transformed, and utilizes the roller bearing travel prolongation mechanism of head sheave long stroke pumping unit, is designed to the pumping unit of the more excellent suitable small-sized short stroke of performance.
The utility model is realized by following scheme, this machine has replaced the retarder of head sheave long stroke pumping unit with a kind of extraordinary chain-driven, transmission system weight is lightened, thereby the transmission system of pumping unit can be contained on the support, and when workover eration and transportation, support can be arbitrary to rear-inclined, and the transportation and the installation that are exactly workover eration and pumping unit like this become more simple and safe.Single crank energy-saving beam pumping unit of the present utility model is by motor, belt transmission, chain-driven, the crank rocker changement, the roller bearing travel prolongation mechanism, balancer weight and sucker rod are formed, motor is through belt transmission, behind the chain reduction, driving crank at the uniform velocity rotates, crank drives rocking bar through connecting rod and swings repeatedly, the wire rope of sucker rod and balancer weight is wrapped on the head sheave, direction is opposite, so head sheave when swing, drives balancer weight and sucker rod and rises repeatedly and descend, sucker rod pumps, reach from oil well the purpose of suction crude oil, balancer weight pumps and is used to offset the load of sucker rod, reduces the moment of torsion of crankshaft.
Further describe the utility model embodiment below with reference to the accompanying drawings,
Fig. 1: the drive mechanism schematic diagram that is the single crank energy-saving beam pumping unit;
Fig. 2: the workover eration key plan that is the single crank energy-saving beam pumping unit;
Fig. 3: the transport position figure that is the single crank energy-saving beam pumping unit;
Fig. 4: the extraordinary chain sprocket structure figure that is the single crank energy-saving beam pumping unit.
Transmission principle of the present utility model is implemented by Fig. 1, and in Fig. 1, motor (1) is contained on the base (12), and all the other transmission systems all are contained on the support (11).The unidirectional rotation of motor (1), drive crank (5) rotation that is contained on the sprocket wheel through band transmission (2) and chain-driven (3), crank (5) drives rocking bar (8) swing through connecting rod (4), roller bearing (6) is rigidly connected with head sheave (7), be stuck in again in the slot rolling of rocking bar (8), drive head sheave (7) by roller bearing (6) again during rocking bar (8) swing and realize putting on angular oscillatory motion.Balancer weight (10) and sucker rod (9) are suspended on the lifting rope of head sheave (7), and winding direction is opposite, and the head sheave swing time will drive balancer weight (10) and sucker rod (9) back and forth rises and descends, and reach to take out from oil well and the purpose of crude oil.Balancer weight (10) be used to the to offset load of sucker rod reduces the moment of torsion of crankshaft.
In the embodiment of the present utility model, workover eration is implemented by Fig. 2, be articulated and connected with hinge B between Fig. 2 medium-height trestle (11) and the base (12), afterbody uses the stretch A that is made up of the turnbuckle screw rod to connect again, and the screw rod that rotates stretch can make support (11) recede and stay enough spaces to workover eration.
In the embodiment of the present utility model, the transportation of pumping unit is implemented by Fig. 3.Lay down and draw an end of stretching bar A, support (11) was fallen backward around hinge B, so that the oil pumping function is transported in level with regard to available crane gear.After transporting to oil well.It is upright straight with crane gear support (11) to be sling, and has just finished the installment work of pumping unit.Therefore make the transportation of pumping unit and installation become more simple and safe.
In the utility model scheme, what the driven sprocket of extraordinary chain-driven (3) adopted is inserted formula gear ring, be with the arrangement of single tooth piece by Fig. 4, be fixed to one by one and obtain on the circumference of wheel disc, but 2,3,4,5,6 times of the interval chain pitch of tooth piece, process sprocket wheel in this way, the process equipment that needs is simple, cost is low.
In Fig. 1, connecting rod (4) and crank (5) are contained in the napex of support (11), and support (11) is not subjected to the influence of crank (5) pulling force, thereby can realize clicking crank drive, single crank is compared with double-crank, be not subjected to two nonsynchronous influences of crank running, thereby manufacturing process is simplified greatly.
Single crank energy-saving oil pump of the present utility model has not only been inherited head sheave long stroke and has been taken out The hoisting power of oil machine is big, power consumption is little, outside the low advantage of cost for oil production, and transportation, Install very simple, convenient.
