The utility model utilizes the empty weight of the two adjacent oilwell rod sets to be as the counterweight for operation, and utilizes a group of reversing motors for driving, the speed reducer for deceleration, and the soft wire rope for transmission, so as to achieve the multiple advantages of energy conservation, high efficiency and low cost.
Description
Technical field
The utility model relates to a kind of energy-saving pumping unit that is applicable to vertical formula oil well, particularly utilizes the counterweight each other of conducting oneself with dignity of the bar group of vertical formula well, utilizes reversing motor to drive, and the flexible steel cable transmission drives two mouthfuls of adjacent oil well bar groups and works simultaneously.
Background technology
Abundant petroleum resources are contained in the Northwest, but because the restriction of its geological condition and ground surface or terrain, and are how in the majority with vertical formula oil well on the arranging of oil well.
The oil pumper of this area mainly still is a unit individual well operational mode at present.The major defect of the operation of this pattern is: (1) is in order to solve the balanced ratio that energy consumption improves oil pumper, what oil pumper adopted in when design is the load that the mode that installs the tail balance weight additional is come the balance oil well, the balanced ratio that this mode is general is all lower, and the power draw of motor is relatively large; (2) adopt the cost of unit individual well pattern oil pumper higher relatively, cause the waste of cost and material.
Summary of the invention
The purpose of this utility model is a kind of energy-saving pumping units that are applicable to vertical formula oil well of research and development, utilize two mouthfuls of adjacent oil well bar groups weight counterbalance operation each other of conducting oneself with dignity, utilize reversing motor to drive, reducer slows down, the flexible steel cable transmission has reached energy-conservation, efficient, the low plurality of advantages of cost.
The technical solution of the utility model: the energy-saving pumping unit of vertical formula oil well that is applicable to of the present utility model comprises the reversing motor that connects successively, reducer, the oil pumper cylinder, wire rope on the oil pumper cylinder, the oil well bar group that is connected with wire rope on the oil pumper cylinder, one end of the wire rope on its oil pumper cylinder is connected on the polished rod eye of first group of oil well bar group by first directive wheel, the other end of the wire rope on the oil pumper cylinder is connected to by second directive wheel on the polished rod eye of second group of oil well bar group, with one group of reversing motor, reducer, the running of oil pumper cylinder drives two groups of oil well bar groups and works up and down.
Advantage of the present utility model: the utility model utilizes two mouthfuls of adjacent oil well bar groups weight counterbalance operation each other of conducting oneself with dignity, and utilizes one group of reversing motor to drive, and reducer slows down, and the flexible steel cable transmission has reached energy-conservation, efficient, the low plurality of advantages of cost.Further improve the balanced ratio of oil pumper, it is energy-saving and cost-reducing to reduce motor load.Bring into play the advantage of a machine twin-well, save the oil pumper materials, reduce manufacturing cost.
