Vacuumizing equipment for liquefied natural gas bottle for double-layer vehicle and vacuumizing method of vacuumizing equipment

Abstract

The invention provides vacuumizing equipment for a liquefied natural gas bottle for a double-layer vehicle and a vacuumizing method of the vacuumizing equipment, and relates to the technical field of vacuumizing devices.The vacuumizing equipment comprises a frame body, a vacuumizing part and a tank body; four universal wheels are mounted on the frame body, and the four universal wheels are in contact with the ground; the vacuumizing part is composed of a mounting seat, an equipment main body, a fixing bolt, a connecting pipe, a connector and a clamping groove, the mounting seat is mounted on the frame body, auxiliary holes are formed in an auxiliary seat in a rectangular array shape, each auxiliary hole is of a semicircular hole-shaped structure, and the auxiliary holes are aligned with a switch mounting seat in position; when the frame body moves, wind can be collected through the auxiliary seat of the rectangular box-shaped structure, the collected wind can be sprayed to the switch mounting seat through the auxiliary holes formed in the rectangular array shape, then dust on the switch mounting seat is cleaned, and problems that when the switch mounting seat is connected with the tank body, the sealing performance is poor, and the connection with the tank body is tedious are solved.

Description

technical field [0001] The invention relates to the technical field of vacuuming devices, in particular to a vacuuming device and a vacuuming method for a double-layer vehicle liquefied natural gas bottle. Background technique [0002] With the high development of modern science and technology, the sealed containers used in industry, commerce, science and research institutions are getting bigger and bigger. Since the manufacturing process cannot be perfect, there are thousands of sealing points, and the sealing device inevitably has the possibility of leakage. , In the process of production and development, the equipment often has problems in material quality, installation, component fatigue and structural design, which reduces the sealing of the system and causes air leakage in the system, so it is necessary to use vacuum equipment for inspection. [0003] However, as far as the current traditional vacuum equipment used for LNG cylinder inspection is concerned, firstly, its...

Problems solved by technology

[0003] However, as far as the current traditional vacuum equipment used for LNG cylinder inspection is concerned, firstly, its tightness is weak when it is connected with the tank body, and it is cumbersome and time-consuming to connect with the tank body; secondly, after a period of use After a period of time, the control panel of the equipment is easy to accumulate dust, which affects the use; finally, when the equipment is disassembled and fixed, the bolt holes need to be aligned repeatedly, and the fixing firmness is low
