Abstract
The invention discloses an energy-saving pulley reducer for oil extraction in an oil field, which solves the problem that the existing pumping unit reducer with a small transmission ratio cannot meet the requirement for stroke frequency and the pulley with an excessive transmission ratio cannot meet the requirement for energy saving. A casing is arranged on one side of the pumping unit reducer, a large gear and an intermediate gear meshed with the large gear are arranged in the casing, an output shaft of the pumping unit reducer is connected with the large gear, and an input shaft of the pulley is mutually meshed with the intermediate gear. The energy-saving pulley reducer is reasonable and reliable in structural design, realizes functions of deceleration, real time detection recording for the mounting of a main reducer load, real time overload alarm and safe poweroff, has the advantages of high mechanical efficiency and low energy consumption, and can be used for the pumping unit with the long stroke and the low stroke frequency in the general oil field, as well as a heavy oil well, a gas-containing oil well and a water-containing oil well.
Description
Technical field
The present invention relates to the pulley decelerates device, be specially a kind of oil extraction in oil field energy-saving belt wheel decelerator.
Background technique
The oil field overwhelming majority of China is low energy, stripper field, unlike external oil field very strong blowing ability is arranged, and most of oil field will come force feed to enter well by water filling, by pumping unit (claiming again the machine of kowtowing) oil is elevated from the stratum.The recoverable amount of China's pumping unit is more than 100,000 at present, and motor installation total capacity is at 3500MW, and a year power consumption exceedes 10,000,000,000 kWh.And the operational efficiency of pumping unit is low especially at present, is 25.96% at China's average operating efficiency, and external average level is 30.05%, and year energy-conservation potentiality can reach tens kWh.In recent years, China's thick oil well, contain gas well, contain the well increasing year by year, but the technique of pumping unit and facts have proved, it is impossible utilizing the way that improves jig frequency to increase the production fluid amount, its as a result thing and be willing to be, aggravate on the contrary the wearing and tearing of pump and each parts, particularly in the situation that thick oil well is even more serious, also can greatly increase simultaneously inspection pump number of times.
At present the oil pump speed reducer that extensively adopts of China oil field is the product in last century, and this retarder gear range little (only having the speed ratio about 30) is restricting the raising of mechanical efficiency, is difficult to satisfy thick oil well, contains gas well, contains the low jig frequency needs of well; In addition, belt transmission is than excessive (between 5-10), and the transmission efficiency of belt gear when low-speed running is low and unstable, so that energy consumption height and the large contradiction of consumption of self appear in belt in the running, be difficult to satisfy long stroke, the energy-conservation requirement of the supporting fractional electric motor of low-frequency-stroke pumping machine.
Summary of the invention
The present invention for solve existing oil pump speed reducer velocity ratio little be difficult to satisfy jig frequency requires and belt transmission than the excessive problem that is difficult to satisfy energy-conservation requirement, a kind of energy-saving belt wheel decelerator is provided.
The present invention adopts following technological scheme to realize: the energy-saving belt wheel decelerator, comprise oil pump speed reducer and belt pulley, oil pump speed reducer one side is provided with housing, be provided with in the housing gearwheel and with the carrier gear of its engagement, the output shaft of oil pump speed reducer is connected with gearwheel, and input shaft and the carrier gear of belt pulley are intermeshing.
During operation, the belt pulley of energy-saving belt wheel decelerator is accepted the energy of motor, input shaft by belt pulley with transmission of power to carrier gear, carrier gear with transmission of power to gearwheel, gearwheel output energy is to oil pump speed reducer, overcome existing oil pump speed reducer velocity ratio little be difficult to satisfy jig frequency requires and belt transmission than the excessive problem that is difficult to satisfy energy-conservation requirement.
Housing one side is provided with the reaction torque strut fixing with ground, the belt pulley output shaft corresponding position of reaction torque strut and housing is provided with the coupling rod hinged with both, be provided with sensor on the coupling rod, can realize that by sensor real-time overburdening is reported to the police and the function of safety outage.
Reasonable in design of the present invention is reliable, overcome that existing pulley decelerates device diameter pulley can not increase, belt pulley axial float, belt pulley Position Design retarder be without spatial position, the belt pulley Position Design retarder problem without the contradiction of small belt pulley spatial position, the real-time detection record function and the warning of real-time overburdening and the safe power down function that have realized deceleration, the main reducing gear load is installed, have advantages of that mechanical efficiency is high, energy consumption is low, can satisfy general oil field long stroke, low-frequency-stroke pumping machine use; Also can satisfy thick oil well, contain gas well, contain long stroke, low-frequency-stroke pumping machine use that well uses.
Jig frequency through 3 types that each manufacturer of existing kind more than 130 is produced, 4 types, 5 types, 6 types, 8 types, 10 types, 12 types, 14 types, 16 type beam pumping units is analyzed average 8.48 times of maximum jig frequency, average 6.82 times of middle jig frequency, average 4.85 times of minimum jig frequency.Suppose 9 times, 7 times, 5 times for desirable jig frequency, its velocity ratio that uses now retarder is about 30 mostly.After these retarders are installed energy-saving belt wheel decelerator of the present invention, make whole reduction speed ratio enlarge 6.3 times, reach about 200; Motor is 1500r/min, and the speed ratio of belt pulley is between 1.5-2.7 the time, and the jig frequency of pumping unit reaches (being desirable jig frequency) 5-9 time, makes the oil pumping unit matching motor power (output) reduce by two grades, average energy-conservation 30%.
