Description
Technical field
The utility model relates to a kind of oil pumper, is a kind of hydraulic pumping unit specifically.
Background technology
Current oil extraction in oil field factory uses the earliest and most widely used mechanical oil recovery equip ment is beam pumping unit.Beam pumping unit complex structure, floor space is large, installs difficulty, and needs civil construction.Beam pumping unit oneself motor power is large in addition, consumes electric energy many, causes its electric efficiency low, and with reduction box, causes its oil pumping degree of depth to be restricted.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, floor space is little, and electric efficiency is high and the oil pumping degree of depth limits little hydraulic pumping unit.
For achieving the above object, the utility model comprises hydraulic cylinder, hydraulic pump, motor and oil conservator, the piston that can move up and down is provided with in described hydraulic cylinder, sucker rod is fixed with in the bottom of piston, coupled logical ventilating pipe is provided with from top to bottom successively at the right-hand member of hydraulic cylinder, oil return pipe and main oil pipe, the left end of described hydraulic pump is provided with oil returning pipe joint, lower end is provided with main oil pipe joint, described oil return pipe has main oil pipe joint to be connected with hydraulic pump with main oil pipe respectively by oil returning pipe joint, the right-hand member of described hydraulic pump is provided with coupled motor, U-shaped branch oil pipe is provided with in the upper end of hydraulic pump, two oil conservators are provided with on the top of U-shaped branch oil pipe.
The connectivity part up and down of described oil return pipe and hydraulic cylinder is respectively eyelet B and eyelet A.
Rubber stopper moving up and down is provided with in described each oil conservator.
By above setting, the utility model power of motor is less, and energy consumption is low, and efficiency is high.The utility model structure is simple, and floor space is little, easy for installation, reduces cost of production, substantially increases oil recovery efficiency.

Detailed description of the invention
As Fig. 1, shown in 2, the utility model comprises hydraulic cylinder 1, hydraulic pump 2, motor 3 and oil conservator 4, the piston 5 that can move up and down is provided with in described hydraulic cylinder 1, sucker rod 6 is fixed with in the bottom of piston 5, coupled logical ventilating pipe 7 is provided with from top to bottom successively at the right-hand member of hydraulic cylinder 1, oil return pipe 8 and main oil pipe 9, the left end of described hydraulic pump 2 is provided with oil returning pipe joint 10, lower end is provided with main oil pipe joint 11, described oil return pipe 8 has main oil pipe joint 11 to be connected with hydraulic pump 2 with main oil pipe 9 respectively by oil returning pipe joint 10, the right-hand member of described hydraulic pump 2 is provided with coupled motor 3, U-shaped branch oil pipe 12 is provided with in the upper end of hydraulic pump 2, two oil conservators 4 are provided with on the top of U-shaped branch oil pipe 12.
Described oil return pipe 8 is respectively eyelet B13 and eyelet A14 with the connectivity part up and down of hydraulic cylinder 1.
Rubber stopper 15 moving up and down is provided with in described each oil conservator 4.
By above setting, the utility model operationally, is divided into following Four processes:
(1) down stroke: sucker rod 6 and piston 5 are descending in hydraulic cylinder 1 under Gravitative Loads, the power fluid of piston 5 bottom is pushed back hydraulic pump 2, and motor 3 drives hydraulic pump 2 to be promoted by hydraulic fluid pressure, power oil pump is entered oil conservator 4.
(2) bottom commutation: at down stroke latter end, piston 5 closes eyelet A14, the late commutation of pressure change hydraulic control pump 2.
(3) upstroke: the power oil be stored in oil conservator 4 oppositely flows back to hydraulic pump 2, and hydraulic pump 2 makes power oil supercharging, and in oil cylinder 1, piston 5 is up under the effect of lower power oil pressure.
(4) top commutation: close to upstroke latter end, piston 5 closes eyelet B13, and the pressure increase in oil return pipe 8, main oil pipe 9 and U-shaped branch oil pipe 12 carrys out the late commutation of hydraulic control pump 2, and then sucker rod 6 and piston 5 start descending.
Claims (3)
1. a hydraulic pumping unit, comprise hydraulic cylinder, hydraulic pump, motor and oil conservator, it is characterized in that: in described hydraulic cylinder, be provided with the piston that can move up and down, sucker rod is fixed with in the bottom of piston, coupled logical ventilating pipe is provided with from top to bottom successively at the right-hand member of hydraulic cylinder, oil return pipe and main oil pipe, the left end of described hydraulic pump is provided with oil returning pipe joint, lower end is provided with main oil pipe joint, described oil return pipe has main oil pipe joint to be connected with hydraulic pump with main oil pipe respectively by oil returning pipe joint, the right-hand member of described hydraulic pump is provided with coupled motor, U-shaped branch oil pipe is provided with in the upper end of hydraulic pump, two oil conservators are provided with on the top of U-shaped branch oil pipe.
