Problems solved by technology

[0002] In recent years, with the advancement of industrialization and urbanization, natural gas has developed rapidly as an economical and environmentally friendly clean energy, and the proportion of natural gas used in the automotive industry has become more and more obvious; however, in the process of filling natural gas for vehicles The management of data, security, and information resources is in a primitive manual management stage
[0003] In the prior art, manual operation is used for data statistics and charging of gas refueling, which not only has a large workload, but also cannot avoid manual errors; moreover, cash transactions are used for gas filling, which increases the possibility of receiving counterfeit money; date, there may not be timely information reminders and the refueling staff still fills the vehicle with natural gas, which poses a threat to safe refueling

Embodiment 1

[0028] This embodiment provides a kind of LNG filling machine, the structure is as follows figure 1 , figure 2 As shown, it includes casing 1, keyboard 2, electronic display 3, small ticket printing outlet 4, ventilation hole 5, liquid filling gun 6, pressure gauge 7, emergency stop button 8, hook 9 and mass flow meter 10, casing 1 It is a cube-shaped structure installed vertically. The casing 1 includes two working surfaces. The two working surfaces are two adjacent sides, which are respectively the working front and the working side. Small ticket printing outlet 4, a pair of ventilation holes 5 are respectively arranged at the upper and lower edges of the working side, and a pressure gauge 7, an emergency stop button 8, a hook 9 and a liquid filling gun 6 are arranged in the area between the upper and lower ventilation holes, and the hook The horizontal position of 9 is higher than the filling gun 6;

[0029] The filling gun 6 is installed on the filling gun seat, the fil...

Embodiment 2

[0034] This embodiment provides a method for operating an LNG liquid filling machine, and the specific steps are as follows:

[0035] A. Check whether there is abnormal looseness at each connection, check whether the valves of the liquid inlet and circulation port are open, push the operating handle lightly to check whether there is any jamming, and then feed in liquefied natural gas to check whether there is any leakage, and then add Power-on self-test of the hydraulic machine, confirm that there is no error message;

[0036] B. Before adding liquid, make sure that there is no pressure at the port of the liquid filling gun, insert the liquid filling gun vertically back into the gun seat, and confirm that the gun and the gun seat are free of frost and impurities;

[0037] C. Press the "pre-cooling" key on the keyboard of the liquid filling machine to start pre-cooling. When the liquid filling machine is pre-cooled to the set temperature, it will automatically complete the pre-...

Abstract

The invention discloses an LNG (Liquefied Natural Gas) charging machine and further discloses an operation method of the LNG charging machine. The LNG charging machine is characterized in that a chassis is in a cubical structure mounted vertically, and comprises two adjacent working faces, namely the front working face and the side working face respectively; a keyboard, an electronic display and a receipt printing outlet are arranged on and formed in the front working face; a pair of air vents is arranged at each of edges of the upper end and the lower end of the side working face; a pressure gauge, a jerk button, a hook and a charging gun are arranged in an area between the air vents at the upper end and the lower end of the side working face; and a horizontal position of the hook is higher than that of the charging gun. The designed LNG charging machine is high in measuring precision; by adopting an advanced dynamic filter technique, the flat characteristic of the precision is ensured, and the measuring precision and the accuracy are ensured; in addition, subsection precision compensation is realized by utilizing a flow compensation technique; zero wander is automatically corrected by an automatic zero setting technique; a temperature sensor is adopted, so that stiffness correction compensation is realized; and interference from an external environment is reduced by adopting a vibration signal isolation technique.
