Technical field
The utility model relates to a kind of Special subsurface pump, and the concrete total accepted way of doing sth oil well pump of a kind of strong keying valve double standing valve that relates to, belongs to oil pumping field of mechanical technique.
Background technique
At present, development along with oil field, the attention that the exploitation of extraordinary oil reservoir is more and more arrived, exploitation technology technology has also obtained further development, but still have deficiency, conventional Heavy Oil is exploited the needs that cold excavating technology can not meet high sticky deep mining, and suction valve and expulsion valve are closed hysteresis, in inclined shaft, suction valve and expulsion valve are not closed completely, and have had a strong impact on the normal operation of oil well and the working life of oil well pump.The standing valve of original oil well pump is single, and oil well is in the process of oil pumping, and from stratum, crude oil out enters in pump by standing valve assembly and discharges ground, and liquid contains a lot of impurity, can wear and tear or liquid erosion standing valve assembly, causes standing valve malfunctioning.
model utility content
Problem to be solved in the utility model is to provide a kind of shortcoming or deficiency that can effectively overcome or avoid existing in above-mentioned prior art, effectively improve suction valve and the expulsion valve of oil well pump and close hysteresis problem, make valve ball Rapid reset, reduce that oil well is acyclic subtracts pump operation, reduce cost for oil production, extend the working life of oil well and oil well pump, improve the total accepted way of doing sth oil well pump of strong keying valve double standing valve of oil well output and development effectiveness.
In order to address the above problem, the utility model by the following technical solutions:
The total accepted way of doing sth oil well pump of strong keying valve double standing valve, comprises pump barrel assembly, in described pump barrel assembly, is provided with the plunger piston assembly that can pump and pump, and the bottom of pump barrel assembly is connected with two cover standing valve assemblies in turn.
Below the further optimization of the utility model to such scheme: pump barrel assembly comprises pump barrel, the two ends up and down of described pump barrel are connected with respectively pump barrel box cupling, internal thread plunger is installed in pump barrel, and the upper end of internal thread plunger is connected with plunger upper part valve bonnet, and lower end is connected with afterbody footstock.
Further optimize: if plunger piston assembly comprises two traveling valve pairs, two traveling valve pairs are arranged in internal thread plunger.
Further optimize: traveling valve pair is comprised of move about valve ball and the valve seat that moves about, the top of described traveling valve pair is provided with the strong keying righting axle of the effect for traveling valve pair being carried out to righting, opening and close rapidly by force and and opens and closes by force righting spring.
Further optimize: described standing valve assembly comprises the first standing valve assembly and the second standing valve assembly connecting successively, and described the first standing valve assembly is connected with the pump barrel box cupling of pump barrel lower end.The lower end of the second standing valve assembly is connected with standing valve and supports pipe nipple.
Further optimize: described the first standing valve assembly comprises standing valve cover, the inside of standing valve cover is provided with standing valve pair, described standing valve pair is comprised of fuel-displaced valve ball and fixed valve base, and the top of described standing valve pair is provided with the strong keying righting axle of the effect for standing valve pair being carried out to righting, opening and close rapidly by force and and opens and closes by force righting spring.
The utility model adopts such scheme, and tool has the following advantages:
1, two cover standing valve assemblies have played the effect of two-way insurance, because liquid contains wearing and tearing and the erosion effect of foul or valve, are easy to make standing valve to damage, and can not affect oil well pump and continue oil pumping after a standing valve is malfunctioning.
2, open and close by force the effect that righting spring can play righting valve ball, when having solved oil well pump and pumping in inclined shaft, valve cuts out the problem of hysteresis, valve ball eccentric wear, has extended the working life of oil well pump in inclined shaft, improve the plot ratio of pump, further improved pump efficiency.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
