Abstract
The invention relates to a chemical feeding pump for an oil well, in particular to a plunger type chemical feeding pump. The technical scheme is that the plunger type chemical feeding pump comprises a pump body, a liquid inlet pipe and a liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are respectively provided with a valve, a piston is arranged in the pump body and connected with a displacement adjusting column, the displacement adjusting column is provided with a spring, the lower end of the spring is contacted with the pump body, a plunger is arranged at the upper end of the spring, and a stroke pointer is arranged between the plunger and the pump body. The plunger type chemical feeding pump has the advantages that power of an oil pumping unit is fully utilized to serve as motive power of the chemical feeding pump, additional power equipment is not required, the chemical feeding pump is simple to maintain and is organically matched with a well opening so that other operation of the well opening is not influenced, the chemical feeding cost is reduced, paraffin removal and corrosion prevention and the like in production are achieved, and a certain burglarproof effect can be achieved.
Description
Technical field
The present invention relates to a kind of oil well dosing pump, particularly a kind of plunger-type dosing pump.
Background technique
In oil field development, can normally produce in order to make oil well, thereby need adding corrosion inhibitor, antiwaxing agent, antisludging agent to reach the purpose of inhibition, wax control, antiscale, dosing pump dosing method commonly used adopts in batches, intermittently adds at present, cause easily the drug effect fluctuation, can not play a role fully, thereby cause the part well to be blocked, or pipeline is corroded, and brings about great losses to production unit.
Summary of the invention
Purpose of the present invention is exactly in view of the foregoing defects the prior art has, and a kind of plunger-type dosing pump is provided, and safeguards simply, organically cooperates with well head, does not affect other operations of well head, can reach to reduce the dosing cost.
Its technological scheme is: comprise the pump housing, liquid inlet pipe and drain pipe, be respectively equipped with valve on liquid inlet pipe and the drain pipe, be provided with piston in the described pump housing, piston connects the discharge capacity adjustable column, the discharge capacity adjustable column is provided with spring, the lower end of spring contacts with the pump housing, and the upper end is provided with plunger, is provided with the stroke pointer between described plunger and the pump housing.
The invention has the beneficial effects as follows: this dosing pump takes full advantage of the power of pumping unit itself as the motive force of dosing pump, do not need to increase other extra power equipments, safeguard simple, organically cooperate with well head, do not affect other operations of well head, can reach and reduce the dosing cost, can solve again wax removal in the production, the problem such as anticorrosion, can also play certain anti-theft function.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention;
Among the upper figure: the pump housing 1, discharge capacity adjustable column 2, spring 3, plunger 4, stroke pointer 5, valve 6, drain pipe 7, liquid inlet pipe 8, piston 9.
Embodiment:
By reference to the accompanying drawings 1, the invention will be further described:
The present invention includes the pump housing 1, liquid inlet pipe 8 and drain pipe 7, be respectively equipped with valve 6 on liquid inlet pipe 8 and the drain pipe 7, be provided with piston 9 in the described pump housing 1, piston 9 connects discharge capacity adjustable column 2, discharge capacity adjustable column 2 is provided with spring 3, the lower end of spring 3 contacts with the pump housing 1, and the upper end is fixing by plunger 4, is provided with stroke pointer 5 between described plunger 4 and the pump housing 1.
The working principle of dosing pump: move down when transmitting from the power of sucker rod, drive connected discharge capacity adjustable lever, the drive pump rod moves downward, pump rod has occupied the lower cavity space of the pump housing, this is because the valve of liquid inlet pipe is closed, the valve that liquid in the pump chamber just backs down drain pipe flows out liquid discharging valve, and then liquid enters sleeve pipe through high pressure hose; When polished rod was up, the rebounding force of compressed spring moved up rapidly pump rod, and at this moment the lower cavity space of pump forms negative pressure state, the valve of drain pipe is closed rapidly, the valve of liquid inlet pipe is opened, and the liquid in the medicine-chest enters the lower cavity of pump by the liquid feed valve of pump.And so forth circulation realizes the continuous dosing to well head.
This dosing pump takes full advantage of the power of pumping unit itself as the motive force of dosing pump, do not need to increase other extra power equipments, safeguard simple, organically cooperate with well head, do not affect other operations of well head, can reach and reduce the dosing cost, can solve again wax removal in the production, the problem such as anticorrosion, can also play certain anti-theft function.
