Abstract
The utility model discloses a tube bundle anti-vibration device for a power station U-tube heat exchanger. The tube bundle anti-vibration device for the power station U-tube heat exchanger comprises two support plates horizontally and symmetrically disposed on two sides of the tails of U-shaped heat exchange tubes, the two support plates are fixed on a tube plate inside the heat exchanger. Support rods are horizontally disposed between the two support plates. A shock-absorbing device is disposed between each two adjacent U-shaped heat exchange tubes and is fixed on the support rods. One shock-absorbing device is disposed between each two adjacent heat exchange tubes and is fixed through the support rods, and the support rods are fixed on the tube plate inside the heat exchanger through the support plates. The tube bundle anti-vibration device is simple in structure and easy to implement, the fact that the tails of the U-shaped heat exchange tubes vibrate violently under impact of steam to damage can be prevented effectively, service life of the power station U-tube heat exchanger can be prolonged, and operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of vibration proof device, relates in particular to a kind of power station U-shaped tubular construction heat exchanger tube vibration proof device.
Background technology
At present, the U-shaped tubular construction heat exchanger of power station use is to be formed by a large amount of U-shaped heat exchanger tubes assemblings.In actual use; The afterbody of heat exchanger U-shaped heat exchanger tube can produce high vibration owing to irregular shape does not have specific supporting construction under steam impringement, be easy to cause the U-shaped heat exchanger tube to damage; Cause the equipment inefficiency, seriously have influence on enterprise's ordinary production.
The utility model content
The purpose of the utility model provides a kind of power station U-shaped tubular construction heat exchanger tube vibration proof device, can prevent the afterbody generation high vibration of U-shaped heat exchanger tube in the U-shaped tubular construction heat exchanger of power station effectively, avoids device damage, prolongs service life of equipment.
The utility model adopts following technical proposals:
A kind of power station U-shaped tubular construction heat exchanger tube vibration proof device; Comprise that horizontal symmetrical is arranged on two gripper shoes of U-shaped heat exchanger tube two sides of tail; Two gripper shoes are fixed on the inner tube sheet of heat exchanger; Be horizontally disposed with support bar between two gripper shoes, the U-shaped heat exchanger tube is provided with damping device between any two, and damping device is fixed on the support bar.
Described damping device adopts vibration damper plate, and vibration damper plate is fixed on horizontally disposed two support bars through pipe box.
Described gripper shoe and support bar removably connect.
The utility model all is provided with damping device between any two at heat exchanger tube, and damping device is fixed through support bar, and support bar is fixed on the inner tube sheet of heat exchanger through gripper shoe again; The utility model is simple in structure; Be easy to realize, can prevent effectively that the afterbody of U-shaped heat exchanger tube from can produce high vibration under steam impringement, the phenomenon that causes the U-shaped heat exchanger tube to damage; Can prolong service life of equipment, increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 among Fig. 1 not with the AA face cutaway view of U-shaped heat exchanger tube;
Fig. 3 is the BB face partial sectional view of Fig. 1.
The specific embodiment
To shown in Figure 3, the utility model comprises that 3, two gripper shoes 3 of two gripper shoes that horizontal symmetrical is arranged on U-shaped heat exchanger tube 1 two sides of tail are fixed on the inner tube sheet 2 of heat exchanger like Fig. 1; Two support bars 4 have been horizontally disposed with between two gripper shoes 3; U-shaped heat exchanger tube 1 is provided with damping device between any two, and in the present embodiment, damping device adopts vibration damper plate 5; Support bar 4 passes a plurality of vibration damper plates 5; And each vibration damper plate 5 both sides respectively is provided with a pipe box 6, and pipe box 6 is enclosed within on the support bar 4 vibration damper plate 5 is played the effect that is fixedly clamped
Support bar adopts the mode of removably connecting to be fixed between two gripper shoes 3 through screw bolt and nut 7.The staff can pass through fastening screw screw bolt and nut 7 fastening vibration damper plates 5, thereby the afterbody that prevents U-shaped heat exchanger tube 1 can produce high vibration under steam impringement, the phenomenon that causes heat exchanger tube to damage.
