Motor Reversing Pumping Unit

Product Details:

Motor reversing pumping unit is a high efficiency and low energy consumption product. It employs the intelligent analog and digital control and uses the switched reluctance motor as the prime mover which the power factor is cosΦ=1. As the transmission of the friction wheel is the working mechanism, the mechanical transmission line is short and the efficiency is high, realizing the reversion of the motor. The starting reversion is stable with low impact. The stroke and stroke frequency can be regulated independently and steplessly. The velocity of the up stroke and down stroke of the polished rod can be controlled respectively.

 Its mechanical efficiency is about two times that of conventional beam pumping unit, its system efficiency reaches to 50%, and energy saving rate is about 46%. The product is an ideal pumping unit to replace conventional beam pumping unit.

Characteristics

Lower installed capacity and mechanical efficiency is over 95%.The electromotor power factor is COSФ≈1,so it can improve the utilization ratio of transformer.The start-up current of motor is so low that it is only 30% of rated current, while the actual load is 150% of rated load. And motor can not be burned because of excellent motor protection system.

Symmetry balance can reach precise.

Stroke and SPM can be regulated steplessly which makes it adaptable for well condition easily in a few minutes. The pump efficiency will be improved accordingly.

High efficiency and low power consumption. In normal cases, the system efficiency can reach 40-50%.

The unit is adaptable for drawing viscous crude and adjusting the parameter properly, it can ease the problem of eccentric wear of sucker rod and tubing.

Work system adopts the friction transmission when the pump is blocked, the friction system can slide to avoid overload, it can stop running automatically for protecting.

Because the center of gravity is set in the frame of unit, it is safe to people and livestock.

 Easy maintenance. Transmission parts has only two inlets of filling lubricant, the electric system is equipped with self-examination indicator when disorder.

 Easy operation. Stroke can be regulated within a few minutes and SPM can be regulated within a few seconds without extra-devices.

 The wireless concentrate monitoring and controlling interface are available.

Transmission structure of work system, which are consist of switched reluctance Motor(1).cycle reducer(2).and friction wheel (3).is set up on the up-platform. Control system is the other part of work system.

Switched Reluctance Motor

Power factor is cosФ=1,mechanical efficiency can reach 95%. It is simple mechanism, reliably working and is adaptable for alternatively rotating frequently.When start-up current is 150% of rated torque, start-up current is 30% of rated current. There is not peak load when working.

Cycle Reducer

It is small and light and suitable for frequently rotating alternatively. It is also high transmission ratio and efficiency,high excess load ability, low breakdown ratio, long operation life, easy maintenance and reliably working.

Friction Transmission Mechanism

Steel rope is flexible and of long operation life.When pump is blocked, raising rope make a slide on the surface of friction wheel for protecting sucker rod and sucker rod pump.
