Description
The invention belongs to the oil field oil rig, is about a kind of fully hydraulic oil pump.
Existing oil pumper adopts lever-type structure, the lever 12 type oil pumpers of, oil pumping amount maximum best as existing technical performance, and one is heavy more than 16 tons, and cost needs 120,000 yuan, and Gao Ri takes out former oil mass 175m
3Thereby exist that volume is big, shortcoming such as weight is big, complex structure, cost height, installation and maintenance inconvenience, production efficiency are low.
The purpose of the invention is the development new pumping unit that a kind of volume is little, in light weight, manufacturing is easy to use, cost is low, production efficiency is high.
The technical scheme of the invention is: adopt hydraulic pump formula structure, promptly adopt motor, oil pump, booster, hydraulic control two-position four-way valve, safety overflow valve, one way valve and plunger displacement pump etc., constitute a kind of fully hydraulic oil pump, thereby replace the oil pumper of lever construction.
Reach example in conjunction with the accompanying drawings and specifically introduce the architectural feature of the invention.
Accompanying drawing is represented the total schematic diagram of the structure of the invention fully hydraulic oil pump.
Referring to accompanying drawing, this fully hydraulic oil pump mainly contains fuel tank (1), coarse filter (2) (10), motor (3), oil pump (4), safety overflow valve (5) (14), fine cleaner (6) (16), hydraulic control two-position four-way valve (7) (17) hydraulic control one-way valve (8) (9) (18) (19), one way valve (11) (12) (20) (22), booster (13), adjustable throttling (15) plunger displacement pump (21), flowline compositions such as (26).
Oil pump (4) joins with fuel tank (1), coarse filter (2), motor (3) and hydraulic control two-position four-way valve (7) respectively; Booster (13) is connected with hydraulic control two-position four-way valve (7), one way valve (11) (12) and hydraulic control one-way valve (9) (8) respectively; One way valve (11) (12) is communicated with coarse filter (10), fuel tank (1) and adjustable throttling (15) respectively; Hydraulic control one-way valve (9) (8) communicates with hydraulic control two-position four-way valve (7) respectively.Attaching has safety overflow valve (5) (14) between one way valve (12) and adjustable throttling (15) reaching between oil pump (4) and the hydraulic control two-position four-way valve (7).Hydraulic control two-position four-way valve (17) is connected with the oil cylinder (27) of adjustable throttling (15) and plunger displacement pump (21) respectively.Plunger displacement pump (21) is connected one way valve (20) (22) and one way valve (19) (18), flowline (26).
When motor (3) drives oil pump (4) running, the hydraulic oil of fuel tank (1) lining arrives oil pump (4) through coarse filter (2), be forced into hydraulic control two-position four-way valve (7) to booster (13), the piston of booster this moment (13) moves right, and hydraulic oil is entered the high pressure chest of booster (13) through coarse filter (10), one way valve (11) by fuel tank (1).The hydraulic oil in the right chamber of booster (13) is through hydraulic control two-position four-way valve (7), fine cleaner (6) oil sump tank (1).Piston stroke end of a period when booster (13), the left cavity pressure of booster (13) increases, and hydraulic control one-way valve (9) is opened, hydraulic control two-position four-way valve this moment (7) commutation, the right chamber oil-feed of booster, piston is to left movement, and stroke is ended, increased pressure, hydraulic control one-way valve (8) is opened, hydraulic control two-position four-way valve (7) commutation, the reciprocal continuous motion of piston of booster (13), the continuous supercharging of hydraulic oil.If when system pressure surpassed design pressure, high-pressure and hydraulic oil flowed back to fuel tank (1) by safety overflow valve (5).Hydraulic oil after the supercharging is earlier after one way valve (12), adjustable throttling (15) is (when surpassing design pressure, high-pressure and hydraulic oil flows back to fuel tank (1) by safety overflow valve (14)), hydraulic control two-position four-way valve (17) is in the piston-less lumen (24) of oil cylinder (27), the cylinder barrel of oil cylinder (27) together with plunger (23) to left movement, one way valve (20) is closed, one way valve (22) is opened, this moment, underground crude oil entered flowline (26) through one way valve (22), and oil cylinder (27) has the hydraulic oil of rod end chamber (25) through hydraulic control two-position four-way valve (7) simultaneously, fine cleaner (16) flows back to fuel tank (1).When oil cylinder (27) cylinder barrel stroke is ended, hydraulic fluid pressure increases, open hydraulic control one-way valve (19) hydraulic control two-position four-way valve this moment (17) commutation, hydraulic oil enters having in the rod end chamber (25) of oil cylinder (27), cylinder barrel moves right together with plunger (23), and one way valve (20) is opened, and crude oil sucks the plunger displacement pump (21) that places former oil reservoir following, one way valve (22) is closed, and this moment, underground crude oil was pumped out by flowline (26).Stroke is ended, and hydraulic fluid pressure increases, and hydraulic control one-way valve (18) is opened, hydraulic control two-position four-way valve (17) commutation.Like this, the cylinder barrel of oil cylinder (27) moves back and forth continuously together with plunger (23), and underground crude oil just is drawn out of continuously.
The oil pump of the invention (4) also can adopt many pumps and usefulness, to improve oil pumping power and oil pumping number of times.
This fully hydraulic oil pump that the invention provides, when adopting the ZB740 oil pump, technical parameter is the 457l/ branch, rated pressure is 160kgf/cm2, maximum pressure is 320kgf/cm2, the diameter of plunger of plunger displacement pump is 160mm, ram travel is 300mm, and reciprocal 300 times of per minute, one of this example oil pumper heavily only has more than 1 ton, and cost only has more than 20,000 yuan, and day takes out crude oil and can reach 2600m3 Because parts greatly reduce on this rod-pumped well, be not only applicable to land and recover the oil, more be conducive to the exploitation of offshore oil field.
This oil pumper of the invention is compared with the lever 12 type oil pumpers of existing oil pumping amount maximum, have weight and can alleviate 15 times, make working ability and can improve 19 times, cost can reduce by 5 times, day oil pumping amount can improve 14 times significant effect, have simple in structure, easy to manufacture, cost is low, in light weight, volume is little, installation and maintenance are convenient, the production efficiency advantages of higher.
