Number of patent application is to have disclosed a kind of intelligent power saving hydraulic pressure inner equilibrium sisters well oil pumper in the patent application of ZL200920032400.5, utilized energy in the adjacent well rod decline process though adopt this method, but this equipment can only be used for sisters' well, individual well or heavy wool well can't use, and equipment adopts traditional horse head suspension strut, equipment is huge, the fabricating cost height, and energy loss is big during operation; Number of patent application is to have disclosed a kind of multi-cylinder combined type full-balanced hydraulic oil pumping unit in the patent application of ZL200920300405.1, utilized hydraulic technique though adopt this method, reduced the energy loss of motion process, but this equipment does not have counterweight and accumulation of energy facility, can not make full use of the potential energy that produces when sucker rod descends, cause a large amount of meaningless energy consumptions.In a word, the deficiency that prior art exists not only causes the energy consumption of pumping unit system bigger, the process operation less stable, and also equipment is various, wastes a large amount of metal material, cost increases.
The utility model content
The purpose of this utility model is: provide a kind of volume little, compact conformation, save the hydraulic pressure sash weight accumulation of energy self-balancing energy-saving pumping unit of the energy.
In order to achieve the above object by the following technical solutions: a kind of hydraulic pressure sash weight accumulation of energy self-balancing energy-saving pumping unit: comprise hydraulic system, the automatic reverse valve, the oil well oil-pumping rod connector, switch board, connecting pipe, support, the balance sash weight, hydraulic cylinder is a double-acting type double-piston rod-type hydraulic cylinder, the balance sash weight is connected by the rope chain with the piston rod on hydraulic cylinder piston top, the rope chain is by pulley support, balance sash weight and hydraulic cylinder separation are on the both sides of support, the oil well oil-pumping rod connector directly links to each other with the piston rod of hydraulic cylinder piston bottom, on the import and export pipeline of hydraulic pump the automatic reverse valve is installed, the hydraulic pressure propulsion cylinder on hydraulic cylinder piston top by pipeline with link together with the import and export of hydraulic pump again after the automatic reverse valve is connected, the hydraulic pressure propulsion cylinder of hydraulic cylinder piston bottom links together with importing and exporting with hydraulic pump after the automatic reverse valve is connected by pipeline again; The switch board that links to each other with power line is connected with hydraulic pump, automatic reverse valve by control line and power supply wire harness.
The hydraulic pump entrance of described hydraulic system is provided with liquid supplementation pipe and fluid infusion jar.
Described automatic reverse valve is electro-hydraulic reversing valve or electro hydraulic valve or motor operated valve.
Be arranged in support with center of effort's line of the piston rod of center of effort's line of on one side the rope chain that is connected with piston rod and hydraulic cylinder on same straight line.
The utility model adopts once the cover hydraulic means and need not to increase extra auxiliary equipment, consumes the lifting that the less energy can be finished all kinds of oil well crude oil.This system recycles by energy, adopts liquid presses piston pole directly to drive the sucker rod motion, has reduced the input of equipment, greatly reduces the energy consumption of system, the energy loss of crude oil lifting process.Adopt the direct accumulation of energy of hydraulic pressure sash weight, the utilization hydraulic circuit operates steadily, characteristic of low energy consumption, develop a kind of simple in structure, energy consumption is low, pumping efficiency is high, reversing impact power is little, easy to maintenance, the self-balancing pumping unit of safety durable.The utility model is applicable to the lifting of various types of oil well crude oil, particularly ultradeep well, big discharge capacity oil well, batch (-type) oil well, heavy crude well, offshore platform oil well, oblique straight well etc.Compare saving steel 30%～40% with traditional beam-pumping unit; Energy-conservation: 30～80%; Stroke exists: 0～8 meter; Jig frequency exists: between 1～20 time, but choose reasonable is set.Adopt intelligence control system and corresponding motor, application automatic reverse valve reverse flow technique simultaneously, realize steadily commutation, stable operation has simple in structurely, reasonable in design, and moving component is few, and maintenance cost is low, the characteristics of long service life.For the popularization of oilfield exploitation power-saving technology provides strong product and technical support.
