Description

Technical Field

[0001] The utility model relates to the technical field of accumulator cooling equipment, in particular to a cooling device for an accumulator body. Background Art

[0002] An accumulator is an energy storage device in hydraulic and pneumatic systems. It converts system energy into compression energy or potential energy at the appropriate time and stores it. When needed, it converts the compression energy or potential energy into hydraulic or pneumatic pressure and releases it to replenish the system. When the system's pressure suddenly increases, the accumulator absorbs this energy to maintain normal system pressure.

[0003] When an accumulator is operating, it generates a large amount of heat, which causes the inflated rubber airbag inside the accumulator to age and rupture easily after being heated, shortening its service life. Therefore, a cooling device is needed to cool it down. Among them, Chinese Utility Model Patent 2023214791154 discloses a cooling device for an accumulator that is easily disassembled and assembled. The device comprises an accumulator housing, an externally mounted disassembly cooling device, a flexible guide tube and a flexible liquid supply tube mounted below the disassembly cooling device, a liquid supply tube connected to the lower portion of the flexible liquid supply tube, and a liquid supply pump mounted at the lower end of the liquid supply tube. The lower end of the flexible guide tube is connected to a cooling and cooling circulation box structure. The utility model can conveniently remove the heat-conducting aluminum cover from the accumulator housing when disassembly and assembly is required; the heat-conducting copper tube can utilize the copper tube semiconductor refrigeration plate to cool the water liquid, but because the heat-conducting aluminum cover is sleeved on the accumulator housing, a serpentine copper tube for conveying coolant is embedded in the interior of the heat-conducting aluminum cover, and no supporting device is provided on the heat-conducting aluminum cover, resulting in the entire disassembled cooling device being prone to sinking under the influence of its own gravity and other factors, which reduces the cooling effect of the cooling device and makes it impossible to cool the medium inside the accumulator in time, causing the internal inflatable rubber airbag to age and rupture due to high temperature, thereby reducing its service life.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] A cooling device for an accumulator body, such as Figures 1 to 4 As shown, it includes a carbon steel cylinder 1 sleeved on the side of the accumulator body 8, a cooling water chamber 14 is provided inside the carbon steel cylinder 1, an inlet pipe 9 connected to the cooling water chamber 14 is installed on the upper part of the carbon steel cylinder 1, and a water outlet pipe 10 connected to the cooling water chamber 14 is installed on the lower part of the carbon steel cylinder 1. The inlet pipe 9 and the outlet pipe 10 are respectively connected to the cooling water tank to form a circulating cooling loop, which is convenient for cooling the accumulator body 8.

[0023] An upper connecting flange 2 and a lower connecting flange 3 are respectively installed at the upper and lower ends of the carbon steel cylinder 1. The upper connecting flange 2 and the lower connecting flange 3 are respectively composed of two flange seats arranged opposite to each other. A stepped groove 17 is provided on the inner side wall where one flange seat contacts the other flange seat. An O-ring for sealing is installed inside the stepped groove 17. The O-ring is made of fluororubber.

[0024] The O-ring is deformed under the extrusion of the two flange seats and fits tightly against the outer wall of the accumulator body, ensuring the sealing between the carbon steel cylinder and the accumulator body.

[0025] A supporting assembly is provided below the lower connecting flange 3 to prevent the carbon steel cylinder 1 from moving downward. The supporting assembly includes a number of protective plates 13 evenly distributed around the circumference of the accumulator body. The ends of adjacent protective plates 13 are connected by a balancing connecting rod 21. The protective plates 13 are connected to the bottom end surface of the lower connecting flange 3 by welding through a vertical plate 15.

[0026] The vertical plate 15 is threadedly equipped with a top screw 16 mirror-set toward the center of the accumulator body. The inner end of the top screw 16 abuts against the side wall of the accumulator body 8, which can clamp the accumulator body. The accumulator body 8 is synchronously connected to the bottom of the carbon steel cylinder 1 through the vertical plate 15 and the top screw 16, preventing the carbon steel cylinder from moving downward under its own gravity, causing an offset between the accumulator body and the cooling cavity 14 and affecting the cooling effect.

[0027] An anti-sway component is also installed on one side of the carbon steel cylinder 1 to protect the carbon steel cylinder. The anti-sway component includes a column 4 installed on the top of the pump body. A horizontal connecting column 6 is provided at the upper end of the column 4. The connecting column 6 is connected to a clamp 7 mounted on the side of the accumulator body 8.

[0028] The clamp 7 includes two clamps arranged in a semi-annular shape, between which a limit clamping plate 18 is clamped and connected by a connecting screw 19.

[0029] A locking bolt 20 is provided at the bottom of the horizontal plate of the limit clamp 18, and the locking bolt 20 is connected to the top of the upper connecting flange 2, which can synchronously connect the upper part of the carbon steel cylinder 1 with the accumulator body to prevent the sealing between the carbon steel cylinder and the accumulator body from being damaged.

[0030] A connecting base plate 5 is provided at the bottom of the column 4, and the connecting base plate 5 is installed at the top of the outer shell of the pump body through a connecting piece 12. It can prevent the carbon steel cylinder from shaking when the pump body is working, causing displacement between the O-ring and the accumulator body 8, affecting the sealing performance.

[0031] The upper portion of the carbon steel cylinder 1 is symmetrically provided with lifting ears 11 for facilitating the installation of the carbon steel cylinder on the outer side of the accumulator body 8 .

[0032] The bottom of the carbon steel cylinder 1 is also provided with a condensate drain pipe 22 for discharging the cooling water inside the cooling water cavity, so as to facilitate maintenance after the cooling water is discharged and replacement of the O-ring.

[0033] During use, due to the tight connection between the column and the top of the pump body, the anti-sway component connects the carbon steel cylinder to the upper part of the accumulator body and the pump body when the pump body is working, stably supporting the carbon steel cylinder and preventing the carbon steel cylinder from shaking due to the operation of the pump body.

[0034] At the same time, the bottom supporting assembly synchronously connects the lower part of the carbon steel cylinder with the lower part of the accumulator body, preventing the carbon steel cylinder from moving downward under its own gravity and ensuring the cooling effect.

[0035] By setting up anti-sway components and support components, the sealing between the carbon steel cylinder, O-ring and accumulator body is ensured, the cooling effect is improved, and the inflatable rubber airbag inside the accumulator is prevented from being damaged by high temperature due to reduced cooling effect, thereby extending the service life of the inflatable rubber airbag inside the accumulator.

[0036] The utility model provides a cooling device for an accumulator body, which ensures the sealing between the cooling device and the accumulator body by installing an O-ring between the carbon steel cylinder and the accumulator body, and ensures the overall stability of the cooling device by arranging a supporting component and an anti-sway component, thereby avoiding the influence of loose fit between the O-ring and the accumulator body due to downward movement or shaking of the carbon steel cylinder, thereby improving the cooling effect and stability of the cooling device, preventing the internal inflatable rubber airbag of the accumulator from being damaged due to high temperature due to reduced cooling effect, and extending the service life of the internal inflatable rubber airbag of the accumulator.
