Problems solved by technology

To this end, a stable and reliable high-pressure natural gas supply system is necessary, and the accompanying low-temperature gas cylinders on the vehicle are stored with liquefied natural gas as fuel. In order to form 34.5Mpa (5000psig) high-pressure and high-density natural gas, currently, external pressurization technology is generally used. There are certain technical defects
Although there is also in-bottle pressurization technology, it is very immature and only in the theoretical research stage, and there are still many technical obstacles to practical application, especially the pressure of the current in-bottle pressurization technology is far lower than the actual 34.5Mpa

Abstract

The invention discloses an internal booster pump of a low-temperature natural gas cylinder for a vehicle, and relates to the technical field of natural gas cylinders. The internal booster pump comprises a hydraulic oil cylinder, a cooling liquid cavity, a balance cavity, a compression cylinder, a piston rod and a filter. The internal booster pump can replace an external gasifier and a booster of aconventional vehicle-mounted LNG gas cylinder. A vehicle-mounted hydraulic system is used for supplying power to drive the internal booster pump to work, the booster pump is provided with a gasification device to exhaust LNG in the low-temperature gas cylinder and to gasify and pressurize the LNG to 34.5 Mpa, and the high-pressure and high-density form of natural gas is kept stable and reliable.

Description

technical field [0001] The invention relates to the technical field of natural gas cylinders for vehicles, in particular to a built-in booster pump for low-temperature natural gas cylinders for vehicles. Background technique [0002] High-pressure and high-density natural gas is a clean energy that can be used by high-horsepower engines as fuel, which can be comparable to diesel engine performance, obtain stronger power, and achieve energy saving and emission reduction. With the promulgation and implementation of the National Sixth Standard and the requirements of the national energy conservation and emission reduction strategy, high-efficiency high-pressure and high-density natural gas will usher in a broader market prospect. It is widely used in heavy trucks, urban buses, marine, power generation, construction machinery and other fields. To this end, a stable and reliable high-pressure natural gas supply system is necessary, and the accompanying low-temperature gas cylind...
