Abstract
The utility model discloses an electromechanic-integrated oil conveying pump which changes a three-pumping oil extraction appliance into a one-pumping oil extraction appliance. The utility model comprises a conveying pipe 1. The utility model is characterized in that the conveying pipe 1 is connected with one end of a pump barrel 2, and the other end of the pump barrel 2 is connected with a fixing valve 3; the outer surface of the pump barrel 2 is connected with a linear motor 4; a plunger piston 5 which is connected with a travelling valve 6 is arranged in the pump barrel 2, and the travelling valve is positioned in the pump barrel 2. The utility model has the advantages of low cost, long service life, and convenient installation and maintenance.
Description
The utility model relates to a kind of pump, especially a kind of oil transfer pump that is used for deep-well oil-extraction.
As mechanical oil recovery, present employed equipment is " three take out "--pumping unit, and sucker rod, oil well pump use jointly." three take out " equipment link is many, aboveground, the down-hole all will be installed, and equipment is huge, and especially sucker rod is easily broken, and causes maintenance difficult, has increased the cost of production that recovers the oil in the oil field greatly.
The purpose of this utility model will be the electromechanical integration oil transfer pump of " one takes out " equipment oil recovery for people provide a kind of change " three take out " equipment to recover the oil exactly.
The technical solution of the utility model is: a kind of electromechanical integration oil transfer pump, it comprises delivery pipe 1, it is characterized in that: delivery pipe 1 is connected with an end of pump barrel 2, the other end of pump barrel 2 is connected to standing valve 3, the outer surface of pump barrel 2 is connected with linear electric motor 4, be provided with plunger 5 in the pump barrel 2, plunger 5 is connected with traveling valve 6 in being located on pump barrel 2.
Described traveling valve 6 can be one or more.
Because the utility model is integrated linear electric motor and plunger pump, therefore realized that change " three take out " oil production equipment recovers the oil into " one takes out ", what oil field employed " three take out " equipment was homemade now is hundreds of thousands unit, if import then needs units up to a million, the utility model then only needs twenties0000 yuan, this shows, reduced cost widely; And because not having machinery between linear electric motor and the plunger contacts, so greatly reduced loss; Because saved sucker rod,, improved working life again, and simple installation, only needed be installed on the down-hole to the utility model, abovegroundly huge pumping unit need be installed again so reduced rate of breakdown.In sum, the advantage of the utlity model has that cost is low, the life-span is long, being convenient to installation, maintenance.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, delivery pipe 1 couples together with pump barrel 2 usefulness pump housing joints 7, linear electric motor 4 are connected on the outer surface of pump barrel 2 with electric machine joint 8, the other end of pump barrel 2 is connected with standing valve 3 by standing valve joint 9, standing valve 3 is seated at deciding on the valve seat 11 by standing valve gland 10, plunger 5 is housed in the pump barrel 2, the internal surface of the outer surface of plunger 5 and pump barrel 2 adopts the Ni base alloy strengthening of different hardness coupling, make decay resistance Gao Yueshi times than stainless steel, overcome easy peeling of chromium plating and nitrogenize boronising, laser hardening C, N such as ooze altogether at not anti-corrosion shortcoming; The novel line structure that has adopted hydrodynamic lubrication again and strike-off, having overcome general plunger pump squeezes sand grains " grinding paste " of broken formation or scrapes " dry friction " phenomenon that cylinder causes, so working life of greatly having improved oil pump, plunger 5 is connected with traveling valve 6 by traveling valve gland 12, traveling valve 6 can be installed one or more as required on plunger 5, as shown in the figure, be installed on the two ends of plunger 5.
During electric motor starting, standing valve 3 is opened, and when traveling valve 6 and plunger 5 moved down simultaneously, traveling valve 6 was opened, and oil enters in the pump barrel 2, and at this moment, standing valve 3 cuts out; When traveling valve 6 and plunger 5 when up, standing valve 3 is opened, oil enters in the pump barrel 2, plunger 5 is sent into oil in the delivery pipe 1 simultaneously.
