Abstract

The utility model discloses a kind of service branch structures of pump for liquid salts, including bottom plate, the outlet elbow being fixed on bottom plate, the ring flange for being fixed on outlet elbow end, it is characterized in that the outlet elbow includes 90 degree of corners of the several sections of dried shrimp Guan Bingcheng being connected, the dried shrimp pipe of latter end is horizontally disposed, the overflow pipe that upper end passes through outlet elbow is additionally provided in outlet elbow, the upper end of overflow pipe is connected firmly with horizontal support plate, and support plate is connected firmly by stiffener plate and bottom plate；The utility model can reduce the hydraulic loss and thermal losses of nozzle, to ensure the normal work of pump for liquid salts.

Description

The service branch structure of pump for liquid salts

Technical field

The utility model is related to a kind of service branch structures of pump, are especially used for the service branch structure of pump for liquid salts.

Background technology

The pumped (conveying) medium of pump for liquid salts is fuse salt, has the characteristics that high temperature, load are big；The outlet pipe and branch of existing pump for liquid salts Fagging couples, and when work, not only the hydraulic loss of nozzle is big, and heat is directly scattered and disappeared by support plate, and thermal losses is high, Yi Ying Ring the normal work of pump for liquid salts.

Invention content

The purpose of this utility model is to be directed to deficiencies of the prior art, provides a kind of outlet pipe knot of pump for liquid salts Structure, it can reduce the hydraulic loss and thermal losses of nozzle, and be easy to maintenance, cleaning, to ensure the normal work of pump for liquid salts.

In order to achieve the above objectives, the service branch structure of the pump for liquid salts of the utility model, including bottom plate, be fixed on bottom plate Outlet elbow, the ring flange for being fixed on outlet elbow end, it is characterised in that the outlet elbow includes the several sections of dried shrimp being connected The dried shrimp pipe of 90 degree of corners of Guan Bingcheng, latter end is horizontally disposed, and the overflow that upper end passes through outlet elbow is additionally provided in outlet elbow Pipe, the upper end of overflow pipe are connected firmly with horizontal support plate, and support plate is connected firmly by stiffener plate and bottom plate.

The utility model reaches approximate rounding off by 90 degree of corners of the several sections of dried shrimp Guan Bingcheng being connected, and can reduce and turn Hydraulic loss at angle, the high temperature fluid in pipe are only conducted heat by stiffener plate and overflow pipe, are not connect directly with support plate upwards It touches, the upward transmission of heat can be reduced, reduce thermal losses, be conducive to the normal work of pump for liquid salts；

The secondary latter end dried shrimp pipe being connected as a further improvement of the utility model, with the dried shrimp pipe of latter end is concentric reducing Pipe, internal diameter are gradually reduced by media flow direction；When shutdown or failure, the fused salt in secondary latter end dried shrimp pipe can flow backwards entrance Fused salt tank body, can avoid high-temperature molten salt outlet section is cooling, solidification, conducive to the turning back on of later stage, overhauls, clears up, to protect Demonstrate,prove the normal work of pump for liquid salts；

In conclusion the utility model can reduce the hydraulic loss and thermal losses of nozzle, and be easy to maintenance, cleaning, from And ensure the normal work of pump for liquid salts.

Description of the drawings

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the A-A sectional views of Fig. 2.

Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1 to Figure 3, the service branch structure of the pump for liquid salts, including bottom plate 1, welding are fixed on the outlet on bottom plate 1 Bend pipe 2, the ring flange 3 for being fixed on 2 end of outlet elbow, the outlet elbow 2 include several sections and weld the dried shrimp Guan Bingcheng being connected The dried shrimp pipe level 4 of 90 degree of corners, latter end is arranged, and is concentric reducing with the secondary latter end dried shrimp pipe 5 that the dried shrimp pipe 4 of latter end is connected Pipe, internal diameter are gradually reduced by media flow direction；The overflow pipe 6 that upper end passes through outlet elbow is additionally provided in outlet elbow 2, The upper end of overflow pipe 6 is connected firmly with the horizontal welding of support plate 7, and support plate 7 is connected firmly by stiffener plate 8 and the welding of bottom plate 1.

The utility model forms outlet elbow 2 by 90 degree of corners of the several sections of dried shrimp Guan Bingcheng being connected, and reaches approximate round and smooth Transition can reduce the hydraulic loss of corner, and the high temperature fluid in pipe is only conducted heat by stiffener plate 8 and overflow pipe 6 upwards, no It is in direct contact with support plate 7, the upward transmission of heat can be reduced, reduce thermal losses, be conducive to the normal work of pump for liquid salts；When stopping When machine or failure, the fused salt in secondary latter end dried shrimp pipe 5 can be flow backwards along certain angle enters fused salt tank body, can avoid high-temperature molten salt and exists Outlet section is cooling, solidification, conducive to the turning back on of later stage, overhauls, clears up, to ensure the normal work of pump for liquid salts.

Claims
