Abstract
The utility model discloses a double liquid inlet low temperature submerged pump pool. The double liquid inlet low temperature submerged pump pool is characterized by comprising a pump cover and a pump pool body, wherein the pump cover is arranged on the pump pool body, the pump pool body is also provided with a groove vehicle liquid inlet pipe and a liquid inlet pipe and a remaining liquid reflux inlet connected with a storage tank; and the pump pool body is also internally provided with a remaining liquid return pipe communicated with the remaining liquid reflux inlet. An LNG (liquefied natural gas) low temperature submerged pump pool provided by the utility model has the advantages that the structure is simple, the conception is novel, the use is convenient, and a low temperature submerged pump pool double liquid inlet design is adopted; and the double liquid inlet low temperature submerged pump pool provided by the utility model improves the pump pool body to adopt a double liquid inlet structure, the groove vehicle liquid inlet pipe can increase the pressure of a pump tank car through a connecting pipe of the tank car, so that a connection pipe port of the pump tank cat is arranged, and the low temperature submerged pump function is more complete.
Description
Technical field
The utility model relates to a kind of low temperature immersed pump pool device, specifically is the low temperature immersed pump pond of the two feed liquor patterns of a kind of LNG immersed pump.
Background technique
Along with the LNG technology in the develop rapidly of China and use widely; The technology of LNG gas station and application are also in develop rapidly and application; Often demand is also very big: the rock gas of (1), LNG volume ratio homogenous quantities is little 625 times, uses so available automobile, train, steamer are transported to the place that does not have rock gas with LNG easily.The rock gas of international trade reaches 25% with what the liquid mode was transported; (2), the LNG efficiency of storage is high, takes up an area of few.Less investment, 10m3LNG storage volume just can supply one day gas for domestic use of 10,000 family residents.(3), LNG compares with gasoline as the vehicle fuel of high-quality, it has the octane value height, the capability of antidetonance is good, engine life is long, fuel cost is low, advantages such as good environmental protection.It can reduce 72% with HC in the gasoline automobile tail gas, and NOx reduces 39%, and CO reduces 90%, and SOx, Pb reduce to zero; (4), the LNG latent heat of vaporization is high, the recyclable utilization of the cold in the liquefaction process; (5), back density is very low because LNG vaporizes, and has only about half of air, has leakage to spread immediately slightly, has reduced the possibility that sets off an explosion; (6), because the LNG composition is purer, burning fully, the burning back generates carbon dioxide and water; So it is good clean fuel, help protecting environment, reduce municipal pollution; Through the deep cooling process, the sulphur composition in the rock gas is separated out, is separated with solid form, more cleans than other fuel; Greenhouse gas emissions are lower during burning, are the energy of a kind of " green ".The low temperature immersed pump is in requisite status in LNG (LNG Liquefied natural gas) the transfusion flow process, and LNG (LNG Liquefied natural gas) low temperature immersed pump function imperfection can not be given the tank car function of increasing pressure when needing for a long time.
The model utility content
The goal of the invention of the utility model is to overcome the problem of above-mentioned existence, this provide a kind of simple in structure, novel, easy to use, adopt two feed liquor patterns to utilize the two feed liquor low temperature immersed pumps pond of low temperature immersed pump to the tank car supercharging.
The utility model is to realize like this; Construct a kind of pair of feed liquor low temperature immersed pump pond; It is characterized in that: include pump cover, pump pond body; Wherein pump cover is arranged on the body of pump pond, also be provided with on the body of pump pond tank car liquid inlet pipe and the liquid inlet pipe that is connected with storage tank and residual night refluxing opening, also be provided with reflow pipe at residual night with residual night, refluxing opening was communicated with in the body of pump pond.
According to the described a kind of pair of feed liquor low temperature immersed pump pond of the utility model, it is characterized in that: said residual night refluxing opening be arranged on liquid inlet pipe directly over.
The beneficial effect of the utility model is: the described LNG low temperature of the utility model immersed pump pond, and simple in structure, novel, easy to use, adopt the two feed liquor designs in low temperature immersed pump pond.Two feed liquor structures are adopted through improving pump pond body in said pair of feed liquor low temperature of the utility model immersed pump pond, can realize that through the tank car liquid inlet pipe pump gives the tank car supercharging, give the tank car supercharging connection mouth of pipe so increased pump, make low temperature immersed pump more perfect functions.

Fig. 2 is the outside schematic representation in described pair of feed liquor low temperature of model utility immersed pump pond.
Fig. 3 is the plan view in described pair of feed liquor low temperature of model utility immersed pump pond.
Among the figure: 101, tank car liquid inlet pipe, 102, residual night reflow pipe, 103, liquid inlet pipe, 104, residual night refluxing opening, 105, pump cover, 106, pump pond body.
Embodiment
Below in conjunction with accompanying drawing 1-3 the utility model is done detailed explanation:
A kind of pair of feed liquor low temperature immersed pump pond, as shown in Figure 1: include pump cover 105, pump pond body 106, wherein pump cover 105 is arranged on the pump pond body 106.The liquid inlet pipe 103 that also be provided with tank car liquid inlet pipe 101 on the pump pond body 106, is connected with storage tank and residual night refluxing opening 104.As shown in Figure 2: said residual night refluxing opening 104 be arranged on liquid inlet pipe 103 directly over.In pump pond body 106, be provided with reflow pipe 102 at residual night, residual night reflow pipe 102 with residual night refluxing opening 104 be communicated with.The utility model adopts two feed liquor designs (comprising that the liquid inlet pipe 103 that is connected with storage tank is connected the tank car liquid inlet pipe 101 of supercharging with tank car), has made full use of low temperature immersed pump function.Two feed liquor structures are adopted through improving pump pond body 106 in said pair of feed liquor low temperature of the utility model immersed pump pond, can realize that through tank car liquid inlet pipe 101 pump gives the tank car supercharging, give the tank car supercharging connection mouth of pipe so increased pump, make low temperature immersed pump more perfect functions.Liquid inlet pipe 103 is connected with storage tank, is used for the storage tank transfusion.Residual night, refluxing opening 104 also was connected with storage tank, was used for returning liquid to storage tank.
Claims (2)
1. two feed liquor low temperature immersed pump pond; It is characterized in that: include pump cover (105), pump pond body (106); Wherein pump cover (105) is arranged on the pump pond body (106); Liquid inlet pipe (103) that also is provided with tank car liquid inlet pipe (101) on the pump pond body (106) and is connected with storage tank and residual refluxing opening at night (104) also are provided with the residual reflow pipe at night (102) that is communicated with residual refluxing opening at night (104) in the pump pond body (106).
