Description
Technical field
The utility model relates to LNG (LNG Liquefied natural gas) and adds pump pool structure in air pump sled, particularly relates to the LNG pump pond of the outer cold insulation of a kind of end cap.
Background technique
Publication number is that the Chinese patent of CN203532187U discloses a kind of pump pool structure for low temperature immersed pump, it designs a cold insulation assembly to reduce the cold loss of end caps in end caps, end caps cold insulation is respond well, and outside cold insulation structure convenient operation and monitoring.It comprises immersed pump and immersed pump fixing device, the end caps of immersed pump fixing device is provided with cold insulation assembly, cold insulation assembly comprises one end to be fixed by fixed cover and low-temperature storage tank, the stuffing box gland that the other end is provided with closed end cap and the vacuum orifice be arranged on stuffing box gland.This cold insulation assembly comprises two-part, and one is cold insulation assembly, and another is interlayer cold insulation assembly, and two assemblies go out to combine to be formed a closed chamber at end cap.Its deficiency is: interlayer cold insulation assembly is combined into a closed chamber by flange and cold insulation assembly, wherein complex structure, installs inconvenient.
Summary of the invention
The utility model provides the LNG pump pond of the outer cold insulation of a kind of end cap, solves the deficiencies in the prior art part.
The technical solution adopted in the utility model is:
The LNG pump pond of the outer cold insulation of a kind of end cap, comprise housing, end cap, end cap is connected with housing by flange, arrange the first cold insulation assembly in housing, arrange the second cold insulation assembly outside end cap, the second cold insulation assembly is made up of Cold-keeping Layer and cover plate, first cold insulation assembly is connected with the first vacuum orifice, cover plate is provided with the second vacuum orifice, Cold-keeping Layer one end is welded on end cap, and the other end welds with cover plate.
Preferably, vacuum powder is provided with in described second cold insulation assembly.
For ensureing cold insulation effect, in described housing, the first cold insulation assembly adopts the mode that interlayer and vacuum are wound around, and the air in interlayer is drained after adopting cold insulation material to be wound around by inner housing, reduces the convection current of gas, conduction, plays the effect of cold insulation.
Advantage of the present utility model and beneficial effect:
1, in housing, the first cold insulation assembly and the outer second cold insulation assembly of end cap are independently arranged, and connect different vacuum orifices respectively, be communicated with therebetween without the need to flange, structure is simple, easy for installation.
2, Cold-keeping Layer is directly welded on end cap, and manufacturing process is simple.
