Since most of the pressurizing pumps used in industry are reciprocating plunger pumps, a common problem of the reciprocating plunger pumps in the pressurizing process is that a pipeline or a device connected with the pressurizing pump is obviously and even severely vibrated due to pulse high-pressure fluid generated by reciprocating motion of a plunger, and on one hand, the vibration is easy to damage equipment and even cause pipeline rupture to generate huge safety problems, and on the other hand, the vibration can cause loss of kinetic energy of reciprocating motion of the plunger to further increase production energy consumption.

The high-pressure fluid vibration damping and stabilizing device 10 also realizes the adjustment and stabilization of the temperature of the fluid in the vibration damping cavity 110 by arranging the heat exchange component 500. By injecting cooling water into the heat exchange component 500 for cooling and exchanging heat, the cooling water after heat exchange can be used for other technological processes requiring heat for extraction, thereby realizing the maximum utilization of energy.
Optionally, the high-pressure fluid vibration-damping and flow-stabilizing device 10 further includes a heat exchange liquid inlet pipe 520 and a heat exchange liquid outlet pipe 530, wherein the heat exchange liquid inlet pipe 520 is connected to the heat exchange inlet, and the heat exchange liquid outlet pipe 530 is connected to the heat exchange outlet.
Preferably, the material of the heat exchange member 500 is a thermal insulation material, which refers to a material having a thermal coefficient of less than or equal to 0.12, for example, polyurethane foam, polystyrene board, phenolic foam, etc.
Further, the heat exchange member 500 has a spherical shape, the heat exchange chamber 510 has a spherical shape, and the outer wall of the vibration absorbing member 100 is spaced from the inner wall of the heat exchange chamber 510 at equal intervals, that is, the heat exchange member 500 is concentric with the vibration absorbing member 100.
The principle of realizing complete vibration elimination of the high-pressure fluid vibration elimination flow stabilizer 10 is as follows: firstly, the fluid filled in the vibration absorption cavity 110 plays a good buffering role, secondly, the impact force of the high-pressure fluid in the vibration absorption cavity 110 on the vibration absorption cavity 110 in all directions can be mutually offset due to the omnibearing reverse symmetry of the spherical cavity, so that the mechanical balance is achieved, the linear velocity of the high-pressure fluid after the high-pressure fluid comes out of the vibration absorption cavity 110 is greatly reduced, and the elimination of vibration is realized.
Example 1
The present embodiment provides a high pressure fluid vibration damping and stabilizing device 10.

Referring to fig. 2, the overall length of the liquid inlet member 200 is 200mm. Wherein, the length of the first liquid inlet portion 210 is 100mm, the outer diameter of the first liquid inlet portion 210 is 53mm, the inner diameter of the first liquid inlet portion 210 is 28mm, and the wall thickness of the first liquid inlet portion 210 is 12.5mm. The length of the liquid inlet transition part 220 is 10mm, the outer diameter is expanded from 53mm to 70mm, and the inner diameter is reduced from 28mm to 12mm. The second liquid inlet portion 230 had a length of 90mm, an outer diameter of 70mm, an inner diameter of 12mm and a wall thickness of 29mm.
Referring to fig. 3, the total length of the tapping member 300 is 200mm. The length of the first liquid outlet portion 310 was 90mm, the outer diameter was 70mm, the inner diameter was 12mm, and the wall thickness was 29mm. The length of the liquid outlet transition pipe is 10mm, the outer diameter is reduced from 70mm to 53mm, and the inner diameter is expanded from 12mm to 28mm. The second liquid outlet 330 had a length of 100mm, an outer diameter of 53mm, an inner diameter of 28mm and a wall thickness of 12.5mm.
When the high-pressure fluid vibration-eliminating flow stabilizer 10 in the embodiment is applied to a liquid carbon dioxide boosting system, when the fluid pressure is boosted from 5-6MPa to 40-45MPa by a high-pressure pump, the boosting process has no vibration, the fluid flow is stable, the noise is small, and meanwhile, the temperature of the liquid carbon dioxide is increased from 8-12 ℃ to 30-35 ℃. In actual production, cooling water can be introduced into the jacket to regulate and stabilize the fluid temperature after passing through the high-pressure fluid vibration damping and stabilizing device 10, and heat energy of the part is utilized by heat exchange of the jacket water, so that the maximum utilization of energy is realized, and the production cost is reduced.
The high-pressure fluid vibration-eliminating and flow-stabilizing device 10 can stabilize high-pressure high-speed fluid and eliminate vibration, namely completely eliminate huge pressure fluctuation in the high-pressure high-speed fluid. The high-pressure fluid vibration-eliminating steady-flow device 10 provided by the invention has the advantages that the vibration-eliminating cavity is a spherical cavity, the radial dimension of one end of the liquid inlet channel close to the liquid inlet interface 120 is smaller than the radial dimension of one end of the liquid outlet channel close to the liquid outlet interface 130, the radial dimension of one end of the liquid outlet channel close to the liquid outlet interface 130 is smaller, the liquid inlet interface and the liquid outlet interface are positioned at opposite positions, the high-pressure high-speed fluid filled in the vibration-eliminating cavity and the acting force of the fluid in the vibration-eliminating cavity on the vibration-eliminating cavity are all-round and reversely symmetrically eliminated, so that the huge pressure fluctuation in the high-pressure high-speed fluid is eliminated, the purposes of no vibration, stable and adjustable performance, large flow and small noise of the fluid pressure boosting system in the boosting process are further realized, and the kinetic energy of the reciprocating motion of the high-pressure fluid plunger pump is effectively converted into heat energy to be utilized.
The high-pressure fluid vibration-eliminating flow stabilizer 10 can also effectively convert the kinetic energy of the reciprocating motion of the high-pressure fluid plunger pump into heat energy. Compared with the traditional vibration reduction flow stabilizer, when the high-pressure fluid vibration reduction flow stabilizer 10 is used, the temperature of the fluid in the vibration reduction component 100 and the vibration reduction cavity 110 can be obviously increased, because the kinetic energy of the reciprocating motion of the plunger of the high-pressure fluid plunger pump is converted into heat energy, the kinetic energy of the reciprocating motion of the plunger is firstly transferred to the high-speed fluid in the liquid inlet component 200, and the high-speed fluid impacts the inner wall of the vibration reduction cavity 110 after entering the vibration reduction cavity 110 to generate heat.
