A tank body, a metering device, an electronic control device, a liquid inlet fast connector and a liquid outlet quick connector are fixed to an automobile chassis. A pump sump is arranged at the bottom of the tank body. A pump system is fixed in the pump sump, extends out of the pump sump in a sealed manner through a pipeline and communicates with the metering device in a sealed manner. The pump system and the metering device are electrically connected with the electronic control device. The low-temperature liquid filling vehicle is simple in structure, free of pre-cooling and is convenient and rapid to use.

Description

A kind of internal pump charging liquid at low-temperature car
Technical field
The present invention relates to a kind of charging liquid at low-temperature car, a kind of internal pump cryogenic liquid of more particularly to a kind of LNG adds Note car.
Background technology
At present, charging liquid at low-temperature car is by the way of low temperature immersed pump is arranged on outside tank body.Low temperature immersed pump is pacified It is mounted in pump pond, pump pond is arranged on tank body rear, is connected by pipeline between pump pond and tank body.Cryogenic liquid flow from tank body to In pump pond, precooling is carried out to pump and pipeline, wait after reaching pre- cool condition, pump could be started.The drawbacks of this traditional design mode It is, before starting pump every time, precooling will to be carried out to pump so as to reach entry condition, the filling stand-by period is long, fills pipeline System complex.
The content of the invention
In order to overcome the shortcoming of prior art, the present invention to provide a kind of internal pump charging liquid at low-temperature car.Its simple structure, It is without precooling, convenient to use.
The present invention solves its technical problem and is adopted the technical scheme that：Tank body, metering device, electricity are fixed on automobile chassis Control device, feed liquor fast joint and go out liquid fast joint, described tank base has pump pond, and pump system is fixed with pump pond, and pump system passes through Seal for pipe joints is stretched out pump pond and is communicated with metering device sealing, and described pump system and metering device are electrically connected with described electric control gear Connect.
The present invention has following advantages：1) theory cryogenic liquid immersed pump being built in tank body, is proposed, by right Pump system and the design in tank base pump pond, realize pump built-in, it is possible to achieve charging liquid at low-temperature car fills low to low-temperature (low temperature) vessel The function of geothermal liquid；2) precooling to pump, is avoided, pump can be opened at any time, shortened the filling time, improve efficiency；3), structure is closed Reason, maintenance easy accessibility.The immersed pump of dynamic loading is fixed on the flange of pump pond, and pump discharge pipeline and control cable are drawn Tank body, realizes reasonable installation of the immersed pump in tank interior；4), pump pond is reasonable in design, sealed reliable, keeps in repair easy accessibility. Ensure there are enough net positive suction heads for immersed pump, pump is successfully sealed in sealed bottom structure tank interior；5), optimize aerating Stand process system, save pump pond, section of tubing and valve etc., save manufacturing cost.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is front view of the present invention；
Fig. 2 is left view of the present invention；
Fig. 3 is principle of the invention figure.
