Description
Technical field
The invention belongs to LNG filling sled technical field, particularly relate to a kind of little chassis and move LNG filling sled.
Background technique
At present along with the popularization of LNG filling sled application, in use occurred that some are difficult to the problem overcome, one is break down in the using process of LNG filling sled, and be difficult to rescue, influence time is longer; Two is that tank car supercharging is comparatively slow in the process of unloading, and the surplus of vehicle speed and LNG is unloaded in impact; Three is to unload storage tank supercharging phenomenon faster from supercharging.
Summary of the invention
A kind of little chassis of conveniently moving is the object of the present invention is to provide to move LNG filling sled, solve with LNG be fuel the vehicle using process such as heavily card in break down, be difficult to rescue, the problem that influence time is longer, provide tank car pumping rate when one can move and unload fast, fully realize the energy-conservation LNG filling sled of unloading from supercharging.
The present invention solves the technological scheme that its technical problem takes: little chassis is fixed filling device, explosion-proof electric apparatus cabinet, pressurized machine, EAG heater, explosion-proof air compressor, pump pond, immersed pump, vacuum line system, pneumatics air pipe line system, filling device electric system and air-operated solenoid valve group; Described filling device electric system and filling device form loading system; Described pressurized machine liquid entering hole seals communicate with tank car liquid phase mouth, storage tank liquid phase mouth, immersed pump liquid outlet respectively, and pressurized machine liquid outlet seals with storage tank gas phase mouth and tank car gas phase mouth respectively and communicates, and forms pressurization system; The import of EAG heater is connected with the diffusion mouth of all safety valves, is formed and diffuses heating system; Explosion-proof air compressor seals with the pneumatics wind main line of prying body and communicates, and forms pneumatics air pipe line system with solenoid valve group and low temperature Emergeny Cutoff Valves; Immersed pump loads in pump pond, is arranged on the extreme lower position that little chassis allows, and forms the power system of filling sled; First, second low temperature Emergeny Cutoff Valves, cryogenic globe valve, low temperature safety check and vacuum line form the vacuum line system of prying body.
1), the design and manufacture on the little chassis of high gooseneck the present invention has following advantages:, and reduce the setting height(from bottom) of immersed pump, the LNG being conducive to storage tank and tank car better enters pump pond, effectively can prevent pump (inhaling empty) idle running, improve the efficiency of pump; High gooseneck has further adapted to the versatility of trailer headstock.2), pressurized machine liquid entering hole is newly-increased is connected with immersed pump liquid outlet, and effectively can improve the speed to tank car and storage tank supercharging, vehicle speed is unloaded in raising, can reduce the residual capacity of storage tank LNG further.3), change tank top liquid entering hole into unload from supercharging tank bottom liquid outlet of unloading, adequately achieve and to unload the same effect with pump, and improve efficiency of unloading, energy saving, decrease pump wearing and tearing, reduce simultaneously because of pump generate heat cause LNG amount of vaporization increase.
