Description

A kind of reciprocating flexible drawing oil pumping mechanism
Technical field
The present invention relates to rod pumping system, and in particular to a kind of reciprocating flexible drawing oil pumping mechanism.
Background technology
Existing rod pumping system generally transmits energy using rigid sucker rod, passes through the up and down reciprocatingly fortune of sucker rod It is dynamic, plunger upward and downward is driven, so as to realize oil pumping, it has simple in construction, strong adaptability, maintenance management convenient and long lifespan The characteristics of, it is the widest mechanical oil production model of current domestic and international application.Because rigid sucker rod is very long in the system, it is conducted oneself with dignity Machine system inefficiency is caused with eccentric wear.With the exhaustion of oil field resource, oil well is more and more deeper, and required sucker rod is also more next It is longer, cause the efficiency of oil pumping system lower, as current oil recovery urgent need to solve the problem.
The content of the invention
It is oversize and cause to take out to solve sucker rod it is an object of the invention to provide a kind of reciprocating flexible drawing oil pumping mechanism The problem of oil system inefficiency.
Reciprocating flexible drawing oil pumping mechanism of the present invention, including oil pipe and plunger pump, the plunger pump include pump Cylinder and plunger, are connected by branch sleeve between the oil pipe and pump barrel, sealing block are provided with branch sleeve, in the sealing The first check valve is provided with block, the second check valve is provided with plunger;Also include pull rope and balancing weight, pull rope is located at In oil pipe, the drive mechanism connection of its upper end and plunger pump, lower end is connected by the upper end of pilot seal component and plunger;It is described Balancing weight is suspended on the lower end of plunger;When drive mechanism pulls plunger up, the first check valve is opened, and the second check valve is closed Close, the fluid in pump barrel is extruded through the first check valve from oil pipe;When drive mechanism stops, balancing weight is pulled under gravity Plunger is descending, the first closed check valve, and the second check valve is opened, and fluid enters in pump barrel through the second check valve.
Further, the pilot seal component includes being arranged on the pilot seal set at sealing block center, and is located in and leads The guide rod being slidably matched therewith into sealing shroud, the upper end of guide rod is connected with pull rope lower end, its lower end and plunger it is upper End connection.
Reciprocating flexible drawing oil pumping mechanism of the present invention, by setting single in branch sleeve and in plunger respectively To valve arrangement, drive plunger up with pull rope, drive plunger descending with balancing weight, the corresponding pump oil and storage for completing oil pumping system Oil, instead of and transmit energy by rigid sucker rod in the prior art, it is to avoid cause oil pumping system to imitate because sucker rod is oversize Rate is low.The present invention is simple in construction, practical.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Fig. 2 is the sectional view in Fig. 1 along line A-A;
In figure:1-pull rope, 2-oil pipe, 3-guide rod, 4-connection sleeve pipe, 5-the first check valves, 6-sealing block, 7-pilot seal set, 8-pump barrel, 9-plunger, 10-the second check valves, 11-balancing weight.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Reciprocating flexible drawing oil pumping mechanism shown in Figure 1, including oil pipe 2 and plunger pump, the plunger pump include Pump barrel 8 and plunger 9, are connected by branch sleeve 4 between the oil pipe 2 and pump barrel 8, sealing block are provided with branch sleeve 4 6, at least two group first check valve 5 is provided with the sealing block 6, the second check valve 10 is provided with plunger 9;Also include leading Messenger 1 and balancing weight 11, pull rope 1 are located in oil pipe 2, the drive mechanism connection of its upper end and plunger pump, and lower end is by being oriented to Seal assembly is connected with the upper end of plunger 9;The balancing weight 11 is suspended on the lower end of plunger 9.
Specifically, the drive mechanism is the wiring roller that positive/negative rotation can be achieved.When drive mechanism is rotated forward, post is pulled Fill in 9 it is up when, the first check valve 5 is opened, and the second check valve 10 is closed, the fluid in pump barrel 8 between plunger 9 and sealing block 6 Extruded through the first check valve 5 from oil pipe 2;When drive mechanism stops or inverts, balancing weight 11 pulls plunger 9 under gravity Descending, the first check valve 5 is closed, and the second check valve 10 is opened, fluid through the second check valve 10 enter plunger 9 and sealing block 6 it Between pump barrel 8 in.
Specifically, the pilot seal component includes the pilot seal set 7 for being arranged on the center of sealing block 6, and it is located in The guide rod 3 being slidably matched therewith in pilot seal set 7, the upper end of guide rod 3 is connected with the lower end of pull rope 1, its lower end and post The upper end connection of plug 9.By the pilot seal component, make motion of the plunger 9 in pump barrel 8 more steady.
As a kind of preferred scheme of the present embodiment, in the plunger 9 along its it is axially arranged have two group of second check valve 10, when When plunger 9 is up, dual-seal is formed between the second check valve 10 and plunger 9, it is ensured that between the second check valve 10 and plunger 9 not Fluid can be revealed, and then improves the efficiency of the oil pumping system.
The operation principle of the oil pumping mechanism is as follows:
When drive mechanism is rotated forward, and is moved upwards by the pulling plunger 9 of pull rope 1, the pump between plunger 9 and sealing block 6 It is about to the first check valve 5 on the valve ball of the first check valve 5 in cylinder 8 cavity pressures rise, sealing block 6 to open, while in plunger 9 The second check valve 10 valve ball under be about to the second check valve 10 and close, the fluid in pump barrel 8 between plunger 9 and sealing block 6 Extruded through the first check valve 5 from oil pipe 2.
When pull rope 1 goes upward to predeterminated position, drive mechanism stops or inverted, and plunger 9 is made in the gravity of balancing weight 11 Moved downward under, the cavity pressure of pump barrel 8 between plunger 9 and sealing block 6 declines, and the valve ball of the first check valve 5 is by back pressure It is about to the first check valve 5 under active force to close, meanwhile, the valve ball of the second check valve 10 is single by being about to second in back pressure effect power Opened to valve 10, the fluid of the lower section of pump barrel 8 enters in the pump barrel 8 between plunger 9 and sealing block 6.
So far, a working cycles are completed.
