Abstract
The utility model relates to the technical field of an oil-well pump, and particularly relates to an energy-saving motor oil-well pump. The energy-saving motor oil-well pump comprises a pump body, wherein the pump body comprises an outer pipe, a pump cylinder arranged inside the outer pipe, and a desilting assembly arranged at the top end of the outer pipe; a plunger and a fixing assembly are arranged inside the pump cylinder; a desilting bag is arranged inside the desilting assembly; the fixing assembly comprises a valve seat, and a valve ball is arranged inside the valve seat. The energy-saving motor oil-well pump disclosed by the utility model can achieve the displacement of a large pump only by a force acted on a small pump, is good in energy-saving effect, strong in sand control ability, long in service life and low in oil production cost, and can play a role of an air bleeding lock.
Description
Technical field
The utility model relates to the oil well pump technical field, especially a kind of energy-saving electrical machine oil well pump.
Background technique
Oil well pump is again deep-well pump, is most important underground equipment in the sucker rod pumping device, is to drive plunger by sucker rod to make upper and lower reciprocating underwell pump.During lower well operations, oil well pump is installed in the bottom of tubing string, be submerged in the well liquid, and by the rod string transferring power, interior liquid in the direct swabbing well.
The oil well pump ubiquity that uses at present contains the problems such as sand, gassiness, hole deviation, eccentric wear, power consumption are large, causes easily the damage of oil well pump and working life short.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of energy saving and dustproof effect good motor oil well pump.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of energy-saving electrical machine oil well pump, comprise the pump housing, the pump housing has outer tube, pump barrel within the outer tube and the desilting assembly that is arranged on the outer tube top is set, be provided with plunger and fixation assembly in the described pump barrel, has a desilting pocket in the described desilting assembly, described fixation assembly has valve seat, is provided with valve ball in the valve seat.
Further, described plunger surface has spray-welding coating, has the erosion control spacing of 4mm～8mm between described plunger and the fixation assembly, and the space that gas exists is very little, can play the effect of venting lock.
Further, described pump barrel internal surface adopts electroplating processes and cover anti-wearing liner to be arranged, long service life.
The beneficial effects of the utility model are, the power that energy-saving electrical machine oil well pump of the present utility model only need act on little pump just can reach large pump delivery, good energy-conserving effect, and the sand prevention ability is strong, can play the effect of venting lock, and long service life, and cost for oil production is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. outer tubes among the figure, 2. pump barrel, 3. desilting assembly, 4. plunger, 5. fixation assembly, 6. valve ball, 7. valve seat.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Energy-saving electrical machine oil well pump as shown in Figure 1, comprise the pump housing, the pump housing has outer tube 1, pump barrel 2 within the outer tube and the desilting assembly 3 that is arranged on the outer tube top is set, be provided with plunger 4 and fixation assembly 5 in the pump barrel 2, has a desilting pocket in the desilting assembly 3, fixation assembly 5 has valve seat 7, is provided with valve ball 6 in the valve seat 7.Plunger 4 surfaces have spray-welding coating, have the erosion control spacing of 4mm～8mm between plunger 4 and the fixation assembly 5, and the space that gas exists is very little, can play the effect of venting lock.Pump barrel 2 internal surfaces adopt electroplating processes and cover anti-wearing liner to be arranged, long service life.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
