Abstract

The utility model discloses a speed-reducing energy-saving drive device for a pumping unit and mainly solves the problems of low pumping efficiency, wasting pumping equipment and wasting energy for the speed-reducing drive device of current pumping unit. The utility model is characterized in that: a bearing base (4) is fixed on a base (3) between a motor (1) and a speed reducer (2) and is provided with a central shaft (7) with a big and a small belt wheels (5, 6) at two ends; the big and the small belt wheels (5, 6) are respectively connected with the belt wheel of the motor (1) and the belt wheel of the speed reducer through a belt (8). The utility model has the advantages of improving pumping efficiency, low cost, not wasting pumping equipment and saving energy.

Description

A kind of oil pumper decelerating energy-saving drive unit

Technical field:

The utility model relates to oil pumper drive unit used in the oil recovery field, oil field, belongs to a kind of oil pumper decelerating energy-saving drive unit.

Background technology:

In oil recovery field, oil field, oil pumper utilizes motor as power source, generally be to adopt speed reducing driving device to come transferring power, along with going deep into year by year of oil field machinery oil process, most of oil well liquid-supplying quantity not sufficient, flowing pressure reduces, and it is too fast to have the used speed reducing driving device jig frequency of oil pumper now, and the coefficient of fullness of oil well pump reduces, pump efficiency descends thereupon, both wasted a large amount of energy, increased the loss of pumping equipment again, though the low jig frequency oil pumper is arranged at present, but change new machine and need bigger fund input again, cost of production is raise, be replaced the deceleration device that gets off simultaneously and also can be reduced utilization rate by idle.

The utility model content:

Existing oil pumper speed reducing driving device pump efficiency is low in order to overcome, loss pumping equipment and the deficiency that wastes energy, the utility model provides a kind of oil pumper decelerating energy-saving drive unit, this oil pumper decelerating energy-saving drive unit can improve pump efficiency, has that cost is low, not loss pumping equipment and characteristics of saving the energy.

The technical solution of the utility model is: this oil pumper decelerating energy-saving drive unit comprises motor, reducer and base, motor and reducer are fixed on the base, fixed bearing block on the base between motor and the reducer, bearing support is built-in with two ends respectively with the jackshaft of large and small belt pulley, and large and small belt pulley connects the belt pulley of motor and the belt pulley of reducer by belt respectively.

The utlity model has following beneficial effect: owing to take such scheme, motor drives big belt pulley on the jackshaft by belt, the belt pulley that small belt pulley on the jackshaft drives reducer again rotates, because the increase of resultant gear ratio, jig frequency reduces, the coefficient of fullness of pump improves, and pump efficiency increases, and output significantly increases, and improved the inequality of down-hole load, reduced impact, increased machine like this reducer, bar, the application life of pump, and used power of motor can reduce by 75%～80%, energy-saving effect is remarkable, simple in structure, cost is low, the not loss pumping equipment and the saving energy.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is scheme of installations of the present utility model.

1-motor among the figure, 2-reducer, 3-base, 4-bearing support, 5-big belt pulley, 6-small belt pulley, 7-jackshaft, 8-belt.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

As Fig. 1 in conjunction with shown in Figure 2, this oil pumper decelerating energy-saving drive unit comprises motor 1, reducer 2 and base 3, motor 1 and reducer 2 are fixed on the base 3, fixed bearing block 4 on the base 3 between motor 1 and the reducer 2, bearing support 4 is built-in with two ends and is with respectively greatly, small belt pulley (5,6) jackshaft 7, greatly, small belt pulley (5,6) connects the belt pulley of motor 1 and the belt pulley of reducer by belt 8 respectively, and motor 1 drives big belt pulley 5 on the jackshaft 7 by belt, the belt pulley that small belt pulley 6 on the jackshaft 7 drives reducer 2 again rotates, because the increase of resultant gear ratio, jig frequency reduces, and the coefficient of fullness of pump improves, pump efficiency increases, output significantly increases, and has improved the inequality of down-hole load, has reduced the impact to reducer 2, increased machine like this, bar, the application life of pump, and used power of motor can reduce 75%--80%, and energy-saving effect is remarkable, and is simple in structure, cost is low, the not loss pumping equipment and the saving energy.

Claims

1, a kind of oil pumper decelerating energy-saving drive unit, comprise motor (1), reducer (2) and base (3), motor (1) and reducer (2) are fixed on the base (3), it is characterized in that: the base (3) between motor (1) and reducer (2) is gone up fixed bearing block (4), bearing support (4) is built-in with two ends and is with large and small belt pulley (5 respectively, 6) jackshaft (7), large and small belt pulley (5,6) connects the belt pulley of motor (1) and the belt pulley of reducer by belt (8) respectively.
