Adjustable type shared balancing device for walking-beam type multiple well linkage oil pumping system

Abstract

The invention discloses an adjustable type shared balancing device for a walking-beam type multiple well linkage oil pumping system. The adjustable type shared balancing device comprises a support, abalancing wheel and a rotating shaft, wherein two sides of the top of the support are each provided with a bearing box, the balancing wheel is arranged between the two bearing boxes and is provided with a balancing disc, balancing blocks symmetrically located on two sides of the balancing disc and driving mechanisms symmetrically located on two sides of the inner portion of the balancing disc, each balancing block is installed into the balancing disc in the radial direction and is connected with the corresponding driving mechanism, the driving mechanisms drive the corresponding balancing blocks to slide in or slide out synchronously in the axial direction of the balancing disc, the rotating shaft penetrates through the two bearing boxes and the balancing wheel at the same time and is coaxially fixed with the balancing wheel, and under supporting of the two bearing boxes, the rotating shaft rotates and drives the balancing wheel to rotate coaxially. The adjustable type shared balancingdevice for the walking-beam type multiple well linkage oil pumping system has the beneficial effects that up and down strokes are balanced in the oil pumping process and arrangement of the balancing blocks for each oil pumping machine of the walking-beam type multiple well linkage oil pumping system is not needed, the number of the balancing blocks is reduced, the starting and running power of a motor is greatly lowered, and meanwhile, the function of the balancing load being adjustable is realized.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an adjustable shared balancing device of a beam-type multi-well linkage pumping system. Background technique [0002] The beam-type multi-well linkage pumping system drives multiple unit pumping units at the same time through one motor, and connects the unit pumping units through couplings to realize power transmission and reduce cost investment. In the prior art, a balance block is installed on the crank of the unit pumping unit, so that the unit pumping unit runs smoothly during operation, and the loads are mutually balanced during the up and down strokes. However, after connecting multiple unit pumping units through the same main shaft, if a balance weight is still installed on the crank of each unit pumping unit, it is not only necessary to increase the starting and operating power of the motor, but also to increase the balance weight The number of uses increa...

However, after connecting multiple unit pumping units through the same main shaft, if a balance weight is still installed on the crank of each unit pumping unit, it is not only necessary to increase the starting and operating power of the motor, but also to increase the balance weight The number of uses increases the cost input and the economic benefits are not optimistic
