Abstract
A split counterweight built-in accumulator is applied to vibroseis vibrators for oil geophysical prospecting, and used for absorbing vibration hydraulic system pressure pulsation and supplementing hydraulic energy. Volume of the accumulator ranges from 1 liter to 5 liters, a diaphragm is arranged in the accumulator, an annular convex plate is processed at the upper end of the outer wall of the accumulator, an upper flange is sleeved on the outer wall of the accumulator, an annular groove is arranged at the lower end of the inner wall of a central hole of the upper flange, the annular convex plate on the outer wall of the accumulator is arranged in the annular groove of the upper flange, the upper flange is pressed to the annular convex plate of the accumulator, a lower flange is sleeved on the outer wall of the accumulator, a lower plane of the annular convex plate of the accumulator is pressed by an upper plane of the lower flange. The split counterweight built-in accumulator has the advantages that use reliability of the diaphragm accumulator is improved, the diaphragm or the accumulator can be changed conveniently by the aid of the flanges for mounting and seal rings for sealing, and the split counterweight built-in accumulator is convenient in field assembly, disassembly and maintenance and meets use requirements. Application shows that the split counterweight built-in accumulator is fine in reliability.
Description
Technical field
The utility model relates to the geophysical prospecting for oil technical field, a kind of device that is used for absorption system pressure pulsation, replenishes hydraulic energy of installing on particularly a kind of controlled source vibrator.It is the built-in accumulator of a kind of split type weight.
Background technique
At present, the built-in accumulator of geophysical prospecting controlled source weight is for absorbing vibration system pressure pulsation and replenishing instantaneous hydraulic energy and design.In order to bring into play the best use of, built-in accumulator mounting point is near more good more apart from actuator.
The previous built-in bag type accumulator of weight that uses of homemade controlled source is mounting flange of welding on the outer cylindrical housing of accumulator, before the welded and installed flange, to pull down leather bag and poppet valve in the accumulator, after finishing, welding needs the installation and processing face, assemble the technological requirement complexity again after cleaning each part then.Simultaneously, built-in bag type accumulator in use also exposes some problems, interior spring tray set screw nut and the poppet valve set screw nut of poppet valve that mainly is the accumulator ingress easily comes off, and anti-shake performance is poor, and the part that comes off enters the damage that causes hydraulic element in the oil duct.
The model utility content
The purpose of this utility model is: provide a kind of split type weight built-in accumulator, be used for the vibrator weight, improve the reliability and the working life of built-in accumulator.
The technical solution adopted in the utility model is: the built-in accumulator of split type weight, mainly to form by upper flange, lower flange and accumulator, and accumulator adopts cylinder bodily form diaphragm accumulator, and the volume of accumulator has barrier film in the accumulator between 1～5 liter; Cylinder bodily form diaphragm accumulator is an outsourcing piece.It is characterized in that: the upper end at the accumulator outer wall is processed with annular boss; Upper flange is enclosed within on the outer wall of accumulator, there is annular groove the lower end of upper flange center bore inner wall, the annular boss of accumulator outer wall is in the annular groove of upper flange, and upper flange is pressed on the annular boss of accumulator, and upper flange can prevent that accumulator from moving upward under pressure.Lower flange is enclosed within on the outer wall of accumulator, and the last plane of lower flange is pressed on the annular boss lower plane of accumulator, and the last plane of lower flange contacts with the lower plane of upper flange.Be that lower flange installs below the outer wall of accumulator, the annular boss lower plane of accumulator is withstood on plane on it, prevents that accumulator from moving downward.
In order to improve the sealing between upper flange and the accumulator outer wall, between upper flange inwall and accumulator outer wall, radial direction seal ring is arranged, prevent that hydraulic oil from flowing out from radial clearance; In order to improve on upper flange lower plane and the lower flange sealing between the plane, between the plane planar seal ring is being arranged on upper flange lower plane and the lower flange; In order to install, make plane sealing on lower flange lower plane and the weight, at the lower plane of lower flange planar seal ring is arranged.By bolt upper flange and lower flange are fixed on plane on the weight, the built-in accumulator of whole split type weight is fastened on the weight.
The beneficial effects of the utility model: the built-in diaphragm accumulator of the split type weight of the utility model, improved the reliability of using; Simultaneously, install, and adopt the seal ring sealing, can be convenient for changing barrier film or accumulator, be convenient to on-the-spot dismounting maintenance, satisfy usage requirement by flange.Show through on probation, the built-in diaphragm accumulator good reliability of split type weight, using effect is obviously improved than existing accumulator.
Description of drawings
Fig. 1 is the built-in accumulator structure generalized section of the split type weight of the utility model.
Among the figure, 1-upper flange, 2-lower flange, 3-accumulator, 4-radial direction seal ring, 5-planar seal ring.
Embodiment
Embodiment 1: with a built-in accumulator of split type weight is example, and the utility model is described in further detail.
Consult Fig. 1.The built-in accumulator of the split type weight of the utility model, mainly form by upper flange 1, lower flange 2, accumulator 3, radial direction seal ring 4, planar seal ring 5, accumulator 3 adopts cylinder bodily form diaphragm accumulator, and the volume of accumulator 3 is 2.5 liters, and a barrier film is arranged in the accumulator 3.Be processed with an annular boss in the upper end of accumulator 3 outer walls; The outer diameter of accumulator 3 is approximately 110 millimeters, and the external diameter of annular boss is approximately 120 millimeters, and the thickness of annular boss is approximately 30 millimeters.
Upper flange 1 is enclosed within on the outer wall of accumulator 3, between upper flange 1 inwall and accumulator 3 outer walls twice radial direction seal ring 4 is arranged.There is annular groove the lower end of upper flange 1 center bore inner wall, and the annular boss of accumulator 3 outer walls is in the annular groove of upper flange 1, and upper flange 1 is pressed on the annular boss of accumulator 3.
Lower flange 2 is enclosed within on the outer wall of accumulator 3, at upper flange 1 lower plane planar seal ring 5 is arranged between the plane on lower flange 2.The last plane of lower flange 2 is pressed on the annular boss lower plane of accumulator 3, and the last plane of lower flange 2 contacts with the lower plane of upper flange 1.
Lower plane at lower flange 2 has planar seal ring 5 one, seals after the installation.
