Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in further detail.
As it is shown in figure 1, a kind of conveying LNG vacuum insulation immersed pump pump pond, including pump cell body 3 and by adpting flange 16 with
Its pump basin lid 1 connected, described pump cell body 3 includes inner housing 31 and shell body 32, is provided with between inner housing 31 and shell body 32
Gap forms vacuum insulation chamber 33, and described shell body 32 lateral wall is provided with the seepage discharging tube that connect internal with vacuum insulation chamber 33
2 and vacuum tube 4, described seepage discharging tube 2 is provided with electromagnetic valve 5, is provided with leakage sensor 6, institute in described vacuum insulation chamber 33
State pump basin lid 1 top be provided with the liquid outlet 7 connected with inner housing 31 and connect with inner housing 31 inside and go deep into inner housing 31 end
The emptying rate of liquid pipe 8 in portion, is respectively equipped with vacuum chamber 9 and lower vacuum chamber 10 bottom described pump basin lid 1 top and pump basin lid 1, on
Vacuum chamber 9 connects with lower vacuum chamber 10, and described lower vacuum chamber 10 lower surface is provided with immersed pump adpting flange 11, described pump cell body 3
Lateral wall is provided with single-chip microcomputer 12 and alarm 13, and the signal output part of described leakage sensor 6 inputs with the signal of single-chip microcomputer 12
End connects, and the signal output part of single-chip microcomputer 12 signal input part with electromagnetic valve 5 and alarm 13 respectively is connected.
