Abstract
The utility model discloses a pumping unit, which is formed by a base, a support, a walking beam and a mule head hinged at the top of the support, an electric control cabinet and a motor which are arranged at the rear parts of a pumping rod and the base, a belt wheel reducer and a crank connecting rod mechanism; and a rear mule head and a balance weight device are additionally mounted at the rear end of the walking beam. The pumping unit has the beneficial effects of balanced operating, small load changing and energy saving as the balance weight device and an F1500.G serial frequency converter capable of adjusting current frequency of a motor are additionally provided.
Description
Technical field
The utility model relates to the oil field equipment technical field, is specifically related to a kind of oil pumper.
Background technology
Conventional beam pumping unit is the indispensable equipment of Petroleum Production: the structure of beam pumping unit by: base and support, electrical control cubicles, motor and the pulley decelerates machine and the crank-link mechanism that prop up the hinged walking beam of top of the trellis and horse head and sucker rod, base rear portion are formed.During work, motor rotates, and by gearbox crank is rotated, and an end of drivening rod push-and-pull walking beam swings up and down horse head, makes sucker rod move up and down the operation of pumping.The overall result of use of this oil pumper is better, and when its weak point was pumping of beam hanger, its stressed load variations was very big, impacts also very greatly, and the deficiency that the expense power consumption can be high is arranged.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and oil pumper that a kind of conserve energy is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of oil pumper described in the utility model, is formed by electrical control cubicles, motor and the pulley decelerates device at the hinged walking beam of base and support, a top of the trellis and horse head and sucker rod, base rear portion and crank-link mechanism, add afterwards horse head and balance weight device in the walking beam rear end.
Further, the F1500-G Series Frequency Converter is housed in electrical control cubicles.
After adopting said structure, the utility model beneficial effect: oil pumper described in the utility model, owing to add the frequency converter that a balance weight device and regulate the F1500.G series of current of electric frequency, so the good effect that running balance, load variations are little, save the energy is arranged.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, existing oil pumper comprises what electrical control cubicles 14, motor 13 and belt pulley 11 reductors 10 at walking beam 5 that base and support 2, support napex are hinged and horse head 4 and sucker rod 3, base rear portion and crank 9 connecting rods 8 mechanisms formed.Energy-saving pumping unit of the present utility model is on the basis of above-mentioned oil pumper, walking beam 5 rear ends increase be equipped with one after horse head 6, be lifted with a balance weight device 12 on the back horse head 6, according to the load condition of sucker rod 3, regulate the weight of counter weight device 12, to reach the balance of walking beam 5 two ends gravity.Energy-saving pumping unit of the present utility model, also in electrical control cubicles 14, add the frequency converter 15 of F1500-G series, frequency converter is used widely in Industrial Boiler, blower fan, pump class at present, because frequency converter can be according to the frequency of the Load Regulation motor of motor, prevent the load impact to motor, the effect of tangible power and energy saving is arranged.1 is well head among the figure; The 7th, tailing axle is the last hinge of connecting rod 8.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
