Abstract
The utility model relates to a drum type pumping unit which comprises a drum, a bracket, fixed pulleys and a power mechanism, and is characterized in that the fixed pulleys are arranged at two ends of the bracket, and the drum is arranged below the bracket; the drum is fixed on the ground foundation, and two ends of the drum are wound with two lifting ropes or chains with opposite winding directions; one end of one lifting rope or chain penetrates through one fixed pulley to be connected with a weight box, and one end of the other lifting rope or chain penetrates through the other fixed pulley to be connected with a suspending device. The drum type pumping unit is reasonable and compact in structure, labor-saving and consumption-reducing; mechanical energy is sufficiently utilized, energy consumption of the motor is reduced, and electricity is greatly saved; meanwhile, the service life of equipment is prolonged, the motor is not required to be placed in a high position, and the mounting cost is reduced; and the arranged pulley is sufficiently utilized, and the manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of cylinder energy-saving beam pumping unit.
Background technology
In oil extraction in oil field process, oil pumper is one of oil production equipment main in oil producing operation.Common beam oil pumper exist stroke less, from great, the deficiency such as occupation of land is many, counterbalance effect is undesirable, reduction box output torque fluctuates large efficiency is low.Although the pylon oil pumper using at present has the advantages such as stroke is long, lightweight, floor space is little, energy-conservation; but mostly also exist operation to step down, do and show that merit unloading is inconvenient, reversing impact is large, nothing is lost defects such as carrying protection, its uniform motion makes oil well pump, and in aspiration procedure, load can not even variation.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reasonable in design, simple in structure, drum type pumping unit that energy consumption is low and easy to operate is provided.
Technology contents of the present utility model is: a kind of drum oil pump, comprise cylinder, support, fixed block, actuating unit, and it is characterized in that described support two ends are provided with fixed block, support below is provided with cylinder; Described cylinder is fixed on basis, ground, and its two ends are wound with respectively two lifting rope or chains that winding direction is contrary; Described two lifting ropes or chain wherein one end of one are connected with ballast box through fixed block, and another one end is passed fixed block and is connected with suspender.
Preferably, one end of the described lifting rope being connected with ballast box or chain is fixed on described cylinder, and is wrapped in clockwise cylinder one end; One end of the described lifting rope being connected with suspender or chain is fixed on described cylinder one end, and is wound around counterclockwise.
Preferably, described cylinder is connected with actuating unit; Described actuating unit comprises reduction box and motor.
Preferably, described cylinder one end cylinder face diameter is greater than the cylinder face diameter of the other end.
Preferably, the cylinder face diameter that described cylinder is connected one end with ballast box is greater than a face diameter of one end that cylinder is connected with suspender.
The beneficial effects of the utility model are: the invention compactness rational in infrastructure, laborsaving consumption reduction; Make full use of mechanical energy, reduce motor power consumption, greatly save electric weight; Meanwhile, increase service life of equipment, do not need the high-order placement of motor, reduce installation cost; Make full use of pulley setting, reduced manufacturing cost.
Brief description of the drawings
Figure 1 shows that the structural representation of a kind of drum oil pump of the utility model.
Figure 2 shows that the structural representation of the utility model cylinder 2.
Detailed description of the invention
As shown in Figure 1, mainly comprise 1, cylinder; 2, support; 3, pulley; 4, actuating unit; 5, ballast box; 6, suspender; 7, pedestal.
Cylinder 1 is fixed on pedestal 7 to the lifting rope that 1 larger one end of face diameter of cylinder is fixed and winding is connected with ballast box 5, the lifting rope that cylinder less one end of face diameter is fixed and winding is connected with suspender; Wherein the lifting rope of the larger end of cylinder face diameter is wrapped on cylinder clockwise; Cylinder face diameter is wrapped on cylinder counterclockwise compared with the lifting rope of small end; Two lifting ropes are respectively through on two pulleys 3 that are fixed on support 2; Said apparatus is all fixed on base 8; Actuating unit 4 comprises motor and reduction box; Actuating unit 4 is connected with cylinder 1.
As shown in Figure 2, be mainly the structural representation of the utility model cylinder 2, the lifting rope of one end that cylinder end face diameter is large is to be wound around clockwise; The lifting rope of one end that cylinder end face diameter is little is to be wound around counterclockwise.
