Description
Technical field
The utility model belongs to oil pumper technical field, relates in particular to a kind of energy-saving device for beam-pumping.
Background technology
Oil pumper is the necessary equipment in traditional oil exploitation, and general each crude oil production well is at least used an oil pumper.Oil pumper in the course of the work, horse head suspension point is subject to two class loads, be static load and dynamic loading (rod string and fluid column load, vibration and shock loading, frrction load etc.), dynamic loading is inertial load, act on the inertial load of suspension point along with upstroke is divided into four-stage by the variation of speed, accelerate increment of load process, at the uniform velocity off-load process, accelerate off-load process and deceleration increment of load process, above-mentioned be that the horse head of corresponding oil pumper drops to the process the oil well pump oil suction of shaft bottom from peak from off-load process at the uniform velocity to the stage of deceleration increment of load process, in the conversion process of energy in above-mentioned stage, there is a process of oppositely generating electricity to electrical network, be oil pumper above-mentioned stage when hollow load the diligent electric energy consuming be only the do work sub-fraction of oil pumping stage consuming electric power of oil pumper full and down, thereby the electric energy that remaining major part is not consumed can cause the reverse impact to work system electrical network, in above-mentioned conversion process of energy, there is energy loss simultaneously, therefore how to utilize the energy in stage that oil pumper flogs a dead horse, avoid impacting work system electrical network, causing energy loss is urgent problem.
Utility model content
Technical problem to be solved in the utility model is: a kind of energy-saving device for beam-pumping is provided, has to solve in traditional oil pumper work using the stage flogging a dead horse, impact the technical problem of work system electrical network and energy loss.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of energy-saving device for beam-pumping, comprise the sector gear on the reducer output shaft that is arranged on described oil pumper, described sector gear is in transmission connection for eliminating the screw pump of back pressure in oil pipeline by transmission device.
As further improvement, described transmission device comprises the power transmission shaft in the frame that is rotatably installed in described oil pumper, described power transmission shaft is provided with a travelling gear, described travelling gear and described sector gear are connected by meshing transmission, and described power transmission shaft is connected by chain gear transmission with the screw rod of described screw pump.
As further improvement, described screw pump is single-screw (single screw) pump.
As further improvement, described single-screw (single screw) pump is communicated with described oil pipeline by oil pipe.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because the output shaft of the reducer of oil pumper is provided with a sector gear, sector gear is in transmission connection for eliminating the screw pump of back pressure in the oil pipeline of oil pumper by transmission device, the energy that utilizes single-screw (single screw) pump that oil pumper is provided at not consumable work system electrical network of the stage of flogging a dead horse directly uses has eliminated the back pressure in oil pipeline, prevent energy loss, energy-conserving and environment-protective, the oil well pipe of simultaneously eliminating back pressure can be accelerated the rate of pumping of oil pumper, improve oil pumper operating efficiency, the energy not being consumed when single-screw (single screw) pump has directly utilized oil pumper to flog a dead horse the stage has in addition been avoided the impact to work system electrical network, select not only simple to operateization of single-screw (single screw) pump, and safe and reliable to operation, use cost is low.
Because transmission device adopts travelling gear, the transmission of driving-chain form, not only simple in structure, and also easy to install, be convenient to safeguard.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 to Fig. 3 is common, a kind of energy-saving device for beam-pumping, comprise the sector gear 2 on the output shaft of the logical reducer 1 that is arranged on oil pumper, sector gear 2 is in transmission connection for eliminating the screw pump of back pressure in the oil pipeline of oil pumper by transmission device 3, and screw pump adopts single-screw (single screw) pump 4.
When use, oil pumper is under the drive of motor, middle by after the transmission of linkage, make the swinging up and down of walking beam 5 of oil pumper become pumping of horse head 8, thereby the piston that drive connects by oil pipeline pumps, realization is drawn to ground downhole oil and completes oil recovery;
The specific works process that the energy that when single-screw (single screw) pump 4 directly flogs a dead horse the stage by oil pumper, work system electrical network provides uses is as follows:
In the tooth portion of the sector gear 2 that reducer output shaft 10 is provided with and transmission device 3, the joggleword section of travelling gear 31 is that the horse head 8 of oil pumper drops to the process of oil well pump from down-hole starts oil suction from peak, sector gear 2 is under the drive of reducer output shaft 10, the tooth portion of sector gear 2 forwards the position of engaging with travelling gear 31 to, now sector gear 2 is with nutating gear 31 to rotate, travelling gear 31 drives power transmission shaft 30 to rotate, now the drive sprocket 34 on power transmission shaft 30 also rotates, then drive sprocket 34 drives driven sprocket 33 to rotate by driving-chain 32, driven sprocket 33 is arranged on the screw rod of single-screw (single screw) pump 4, now driven sprocket 33 drives the bolt rotary of single-screw (single screw) pump 4, be that single-screw (single screw) pump 4 is started working, because single-screw (single screw) pump 4 is communicated with the oil pipeline of oil pumper by oil pipe 6, single-screw (single screw) pump 4 is just by the back pressure sucking-off in oil pipeline like this, utilize the energy that above-mentioned idle work cannot consume directly to eliminate the back pressure in oil pipeline, energy-conserving and environment-protective, also accelerated rate of pumping simultaneously, increase work efficiency.
While starting oil suction action to oil well pump, now the tooth portion of sector gear 2 just in time turns over travelling gear 31, no longer engage with travelling gear 31, by the time horse head 8 is that horse head declines the stage flogging a dead horse again from peak drops to oil well pump oil suction, the tooth portion of sector gear 2 forwards the position of engaging with travelling gear 31 again to, again drive single-screw (single screw) pump 4 to work, recycling single-screw (single screw) pump 4 uses not consumable above-mentioned idle work stage energy, so circulation, therefore the course of work of above-mentioned single-screw (single screw) pump 4 is intermittent movement, adopt single-screw (single screw) pump 4 simple to operateization, reliable safety, economical and practical.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of making within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
