The outer barrel is fixedly arranged on the bottom plate; the inner barrel is fixedly arranged in the outer barrel; a heat insulating layer is wound on the outer wall of the inner barrel; the side wall of the outer barrel is provided with a vacuumizing interface; the outer wall of the outer barrel is fixedly connected with a liquid inlet pipe and a liquid outlet pipe; both the liquid inlet pipe and the liquid outlet pipe extend to the side wall of the inner barrel and are communicated with an inner cavity of the inner barrel; and the immersed pump is fixedly arranged in the inner barrel. The low temperature pump tank provided by the utility model has low heat conductivity, anti-radiation heat transmission, high heat insulating performance and light weight and is convenient to install and disassemble.
Description
Technical field
The utility model relates to a kind of pump pond, particularly a kind of cryopump pond.
Background technique
Along with the enhancing of the world to environmental protection consciousness; rock gas is as a kind of novel clean energy resource; be applied in the every field of national economy more and more widely,, rise just day by day in a lot of cities of China and area and promoted and use as automobile fuel with substitute gas gasoline, diesel oil.Rock gas is as automotive fuel, and burning is complete, the few carbon distribution of motor, and burning is turned round steadily, and noise is little, has reduced vapour lock and pinking, makes the engine life prolongation, and maintenance expenses significantly reduces.According to the sample analysis contrast, the LNG automobile is compared with fuel vehicle, and the noxious emission of LNG automobile reduces about about 85%, comprehensive carbon emission reduces about about 95%, emission reduction effect is remarkable, is desirable alternative fuel of present stage, rises significant to the PM2.5 that reduces in the environment.The LNG Liquefied natural gas of coming out from the LNG storage tank (LNG) pressure, temperature is on the low side, and as directly be filled into the LNG vehicle-mounted bottle of automobile without increasing temperature and pressure, the not enough filling of pressure slowly can not be filled into capacity rating on the one hand; On the other hand because the LNG temperature of injecting is low, directly cold excessively LNG is charged in the gas cylinder, to cause that its saturated vapor pressure is lower (to have only 0.2～0.3MPa), can not reach the required supply gas pressure of motor (requiring more than the 0.8MPa), cause engine power output not enough, the phenomenon that occurs can't run.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of before LNG injects the LNG vehicle-mounted bottle, and it is carried out the cryopump pond of increasing temperature and pressure.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of cryopump pond, comprise base plate 9, outer cylinder body 6, inner barrel 5 and immersed pump 7, described outer cylinder body 6 is fixedly mounted on the described base plate 9, described inner barrel 5 is fixedly mounted in the described outer cylinder body 6, the outer wall of described inner barrel 5 is wound with thermal-protective coating, the sidewall of described outer cylinder body 6 offers and vacuumizes interface 10, the outer wall of described outer cylinder body 6 is connected with liquid inlet pipe 4 and drain pipe 8, described liquid inlet pipe 4 and drain pipe 8 all extend to the sidewall of described inner barrel 5 and are communicated with the inner chamber of described inner barrel 5, and described immersed pump 7 is fixedly mounted in the described inner barrel 5.
Further, the top of described outer cylinder body 6 is installed with flange 3, and the top that described inner barrel 5 is positioned at described outer cylinder body 6 and described inner barrel 5 is fixedly connected on the described flange 3.
Further, cooperate on the described flange 3 blind flange 2 is installed, described immersed pump 7 is fixedly mounted on the described blind flange 2.
Further, offer mounting hole on the described base plate 9.
Further, described thermal-protective coating is alternately covered by glass fiber paper and aluminium foil and forms.
(3) beneficial effect
The utility model cryopump pond, the liquid entering hole of rock gas in the storage tank from the pump pond entered the inner barrel of pump, after the process cryopump is suppressed, inject vehicle-mounted bottle from the outlet at top, charge in the gas cylinder through beating saturated natural gas, just can satisfy the requirement of automobile supply gas pressure, make gas-fueled vehicles be able to normal operation; The utility model cryopump pond, thermal conductivity is low, radiation proof heat transfer, heat-shielding performance height, in light weight, and installation and removal are convenient.
Description of drawings
