Abstract
The utility model discloses a hydraulic spring energy-storage type pumping unit which is designed to achieve the goal of high production efficiency, miniaturization and easiness in maintenance of the pumping unit. An oil inlet end of a pumping unit energy storage tank is connected with a manual ball valve A, an oil inlet solenoid valve and a piston cylinder; and an oil outlet end of the pumping unit energy storage tank is connected with a manual ball valve B, a motor, an oil pump, an oil discharging solenoid valve and the piston cylinder. A piston and a piston rod fixedly connected with each other, an upper stroke limit switch, a lower stroke limit switch and an energy storage spring are arranged in the piston cylinder. The top of the piston cylinder is connected with a piston breather valve for balancing pressure of the top of cylinder and the outside, and an annular air bag for assisting the spring in storing energy is arranged at the bottom inside the cylinder. The hydraulic spring energy-storage type pumping unit can meet the oil well production requirements and is high in production efficiency, stroke frequency can undergo stepless regulation, energy-saving effects are good, and the hydraulic spring energy-storage type pumping unit is small in size and mass, moves flexibly, is convenient to maintain and is of great practical significance for energy saving and consumption and cost reduction in oil field production.
Description
Technical field
The utility model relates to a kind of hydraulic spring grease cup energy storage type oil pumper, belongs to oil field extraction equipment technical field.
Background technology
Beam-pumping unit has exposed energy consumption height and inefficient problem in long-term use procedure, beam pumping unit has huge balance weight, huge reducer and quadric chain, use old-fashioned belt transfer structure, in operation process, can expend a large amount of kinetic energy; Beam-pumping unit has the fuselage of huge heaviness, and the workload of installation and maintenance is very large, needs many platform trucks and crane coordinated manipulation when lifting, expends a large amount of manpower and materials, and maintenance cost is high, and the stroke jig frequency is regulated more complicated, and operation easier is large.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic spring grease cup energy storage type oil pumper, be a kind of have energy-conservation, efficient is high, miniaturization and be easy to the new pumping unit of advantages such as safeguarding.
Concrete technical scheme of the present utility model is as follows:
The energy storage canister oil inlet end connects manual ball valve A, oil-feed electromagnetic valve and piston rod by high-pressure hose, and the oil extraction end connects manual ball valve B, motor and oil pump, oil drain solenoid valve and piston rod by high-pressure hose.Be provided with mutually affixed piston and piston rod in the piston rod, the piston rod top is provided with the upstroke limit switch, and the bottom is provided with down stroke limit switch and energy-stored spring.The piston rod top connects the piston breather valve of compensating cylinder top and ambient pressure, and the cylinder inner bottom part is provided with the annular air-pocket of assisting the spring storage power.
Hydraulic spring grease cup energy storage type oil pumper can satisfy the requirement of oil mining, and production efficiency is high, but stroke jig frequency step-less adjustment, good energy-conserving effect, volume and quality are little, and migration is flexibly, easy to maintenance, the energy-saving and cost-reducing of field produces and reduction cost there are important practical significance.
Description of drawings
Fig. 1 is hydraulic spring grease cup energy storage type oil pumper schematic diagram.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
Motor and oil pump 1, high-pressure hose 2, manual ball valve 3, oil drain solenoid valve 4, oil-feed electromagnetic valve 5, piston rod packing device 6, piston rod 7, piston 8, piston rod 9, upstroke limit switch 10, down stroke limit switch 11, energy-stored spring 12, switch board 13, energy storage canister 14, piston breather valve 15 and annular air-pocket 16 form;
The operating principle of hydraulic spring grease cup energy storage type oil pumper is as follows:
After the utility model oil pumper is installed in well mouth of oil well, be connected with piston rod packing device 6.When starting rear upstroke, two manual ball valves 3 are all opened with oil drain solenoid valve 4, and oil-feed electromagnetic valve 5 cuts out, and motor and oil pump 1 start, and hydraulic oil enters piston rod 7 by energy storage canister 14, and energy-stored spring 12 releases energy, and piston 8 is produced upwards thrust; When this thrust during greater than the lower pulling force sum of 9 deadweights of piston 8 and piston rod and piston rod 9, piston 8 moves upward, and oil pumper enters upstroke.
Under the control of upstroke limit switch 10 and switch board 13 time relays, when oil pumper reached default stroke, oil drain solenoid valve 4 was closed, and oil-feed electromagnetic valve 5 is opened, hydraulic oil flows back to energy storage canister 14 by piston rod 7, and hydraulic oil is reduced gradually to the thrust of piston 8; When this thrust during less than the lower pulling force sum of 9 deadweights of piston 8 and piston rod and piston rod 9, piston 8 moves downward, and oil pumper enters down stroke.
When piston 8 dropped to piston rod 7 bottom, compressed energy-storage spring 12 storage power were under down stroke limit switch 11 and switch board 13 time relays are controlled, when oil pumper reaches default piston rod bottom, oil drain solenoid valve 4 is opened, and oil-feed electromagnetic valve 5 cuts out, and oil pumper enters upstroke again.
