Abstract
A device for maintaining a lifting rope of a pumping unit comprises an engine oil tank (1), a one-way throttle valve (2), a hydraulic cylinder (3), a one-way liquid pressure regulating valve (4), an oil supply pipeline (5), a pumping unit walking beam (6), a hydraulic plunger (7), a plunger compression bar (8), an oil atomizer (9) and the lifting rope (10) of the pumping unit. The device for maintaining the lifting rope of the pumping unit is characterized in that the engine oil tank (1), the one-way throttle valve (2), the hydraulic cylinder (3), the one-way liquid pressure regulating valve (4), the oil supply pipeline (5) and the oil atomizer (9) are connected in sequence, the hydraulic plunger (7) is arranged in an inner cavity on the top of the hydraulic cylinder (3), and the plunger compression bar (8) is arranged at the top end of the hydraulic plunger (7). The device can be used for maintaining the lifting rope of the pumping unit timely by adding engine oil.
Description
Affiliated technical field
The utility model relates to a kind of plait of pumping unit care device on the oilfield, organic fuel tank [1], one-way throttle valve [2], oil hydraulic cylinder [3], unidirectional fluid pressure modulating valve [4], oil supply line [5], walking beam on pumping units [6], hydraulic plunger [7], plunger depression bar [8], oil sprayer [9], plait of pumping unit [10] form, adopt this device in time to annotate the machine oil maintenance to the hair plait of pumping unit, prolong the working life of plait of pumping unit.
Background technique
At present, known technology is not establish the plait of pumping unit care device on oil well, and in the production process of oil well, maintenance damages because plait of pumping unit can not get in time often, thereby has affected on the crude oil and produced the working life of impact hair plait.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of plait of pumping unit care device, adopts this device in time to annotate the machine oil maintenance to the hair plait of pumping unit, prolongs the working life of plait of pumping unit.
The technological scheme that its technical problem that solves the utility model adopts is: adopt a kind of plait of pumping unit care device, organic fuel tank [1], one-way throttle valve [2], oil hydraulic cylinder [3], unidirectional fluid pressure modulating valve [4], oil supply line [5], walking beam on pumping units [6], hydraulic plunger [7], plunger depression bar [8], oil sprayer [9], plait of pumping unit [10] forms, it is characterized in that: sump [1], one-way throttle valve [2], oil hydraulic cylinder [3], unidirectional fluid pressure modulating valve [4], oil supply line [5], oil sprayer [9] is linked in sequence, top inner chamber at oil hydraulic cylinder [3] arranges hydraulic plunger [7], on the top of hydraulic plunger [7] plunger depression bar [8] is set.One end of plunger depression bar [8] is connected with hydraulic plunger [7], the other end is connected with walking beam on pumping units [6], when walking beam on pumping units [6] is done when pumping, plunger depression bar [8] drive hydraulic plunger [7] is also done simultaneously and is pumped, the each time to-and-fro motion of hydraulic plunger, the capital is with part machine oil inhalant liquid cylinder pressure [3] inner chamber in the sump [1], then, through unidirectional fluid pressure modulating valve [4], oil supply line [5], oil sprayer [9], machine oil is sprayed on the plait of pumping unit [10], adopts this device in time to annotate the machine oil maintenance to the hair plait of pumping unit.
The beneficial effects of the utility model: by site test, the utility model compared with prior art adopts this device in time to annotate the machine oil maintenance to the hair plait of pumping unit, prolongs the working life of plait of pumping unit.
