Description
Technical field
The present invention relates to a kind of its manufacturing methods of oil field equipment accessory., especially oil field oil pump scrape sand device and its
Manufacturing method.
Background technology
Oil well pump is a kind of common pumping unit crude oil in well being extracted on ground, and existing oil well pump is mainly by upstream
Dynamic ball cover, upper ball sealer, upper sealed ball seat, upper fixed valve union, upward-traveling valves connector, plunger, pump barrel, middle travelling valve bonnet, in
Ball sealer, middle sealed ball seat, sealing seat cover, middle fixed valve union, lower standing valve cover, lower ball sealer, lower sealed ball seat, lower fixation
Valve union forms；Its oil pumping mode is crude oil to be promoted from lower to eminence by the up and down motion of plunger and crude oil from shaft bottom
It is inside extracted on well outside output well, is blocked between pump barrel and plunger due to containing the easy aggregation of sand grains in crude oil, after long-term accumulation
The up and down motion of the plunger of oil well pump can be blocked and be stopped, therefore the plunger outer wall face of oil well pump is provided with multiple recess
The poly- husky slot in right angle, to slow down obstruction of the sand grains to oil well pump, but also undesirable, sand grains can gather sand after work a period of time
Slot, final or obstruction oil well pump are stopped, and oil well pump card machine crash problem are caused, so we are by practice analysis and grind
Study carefully design, invents a kind of oil field oil pump and scrape sand device to solve the problems, such as this.
Invention content
In order to overcome the shortcomings and deficiencies of existing oil well pump, a kind of oil field oil pump of present invention offer to scrape sand device, to
Solve the problems, such as that oil well pump card machine crashes.
The technical solution adopted by the present invention to solve the technical problems is：One oil field oil pump that can be strike-off of design is strike-off dress
It sets, device prevents the sand grains in crude oil from entering plunger and pump between the upper travelling ball cover and upward-traveling valves connector of oil well pump
Cylinder between, oil well pump card machine crash caused by solving the problems, such as the sand sedimentation in crude oil suitable for reading, and to the plunger of oil well pump with
Pump barrel has protective effect, reaches increase service life, reduces the purpose that failure improves oil recovery efficiency.
The oil field oil pump is scraped sand device and is made of sand hole straight coupling and scraper rings.
The sand hole straight coupling is straight-through for tubulose, and upper port is equipped with upper screw socket；Lower port is equipped with lower screw socket；Middle part is equipped with
Cutter groove is equipped with back sand hole at cutter groove.
The scraper rings are circular ring shape, are equipped with knife circumferential weld, magnify collar extension when being easily installed；The section of ring muscle is in rib
Shape, the low outside diameter wall of inner diameter wall is high, forms two blades up and down；Further pump barrel is made in order to avoid scraper rings work long hours
At seam trace and to influence service life long, knife circumferential weld is arranged to R-joining, i.e. the disk angle of knife circumferential weld and scraper rings is：It is interior
Angle 40 to 50 is spent, and exterior angle 130 to 140 is spent.
The sand hole straight coupling and scraper rings are combined as：Scraper rings are collapsed to the cutter groove opened and be nested in sand hole straight coupling
In.
The beneficial effects of the invention are as follows；Card machine caused by capable of solving the sand sedimentation in oil pump plunger piston crude oil suitable for reading crashes
Problem improves oil well pump rate of pumping, oil pumping yield；Oil well pump failure rate is reduced, maintenance personnel is reduced；Improving the pump of oil pumping makes
Use the service life；Improve the working efficiency and oil recovery economic benefit of oil well pump.
