Description

The double type energy-saving pumping unit

Technical field:

The utility model relates to and has a kind ofly changed the rotation of motor into song by assembly pulley and wire rope and draw the mechanically operated oil pumper of double type.

Background technology:

Domestic widely-used oil pumper has beam type and no beam type two classes at present, and based on beam type, its frame for movement causes the lot of energy loss, has reduced the operating efficiency of whole oil pumper; Its distribution motivation great majority are Y series motor; Beam pumping unit adopts band to carry the across-the-line starting formula, required detent torque is bigger, the electric motor starting electric current is a 6-8 times of rated current, for the power that satisfies start request institute gas-distributing motor is bigger, and the required torque when operation of this machine is less, and the motor load more than 90% is below 50%, the oil pumper required motor mostly is in the light running state for a long time, load factor is extremely low, and power attenuation is big, and energy waste is serious.

Summary of the invention:

In order to address the above problem, the utility model provides a kind of double type energy-saving pumping unit, its high efficiency, and energy loss is few in the motion process; The oil extraction cost is low, energy-saving and emission-reduction.

Technical scheme: a kind of double type energy-saving pumping unit, it comprises pedestal, pylon, electric control box; Described pedestal is provided with reluctance motor, and reluctance motor is connected with electric control box, and eccentric wheel assembly is connected with reluctance motor; Walking beam and pylon flexibly connect, one end of adjusting rod and pylon flexibly connect, the other end of adjusting rod and walking beam flexibly connect, the front end of walking beam is provided with front component, the middle part of walking beam is provided with the breast wheel assembly, the tail end of walking beam is provided with tail-wheel assembly, and an end of wire rope is fixed on the tail-wheel assembly, and the other end of wire rope is walked around eccentric wheel assembly, breast wheel assembly and front component and is connected with sucker rod.

The beneficial effects of the utility model, a kind of double type energy-saving pumping unit, it has changed the rotation of motor into song by assembly pulley and wire rope and has drawn the double type machine driving, high efficiency, energy loss is few in the motion process; It adopts reluctance motor, the efficient height, and good energy-conserving effect, electric motor structure is simple, and running cost is low, and reliable operation is fit to environment such as various abominable high temperature; Use the utility model, the oil extraction cost is low, energy-saving and emission-reduction.
