Some suggestions on purchasing and using pneumatic lifting rod
Some news media and the Internet have published the news that the swing chair was injured by the pneumatic lifting rod blasting. Through the discussion of experts on the Internet and the media, we know that these goods are basically three-no goods, therefore, it is advocated that consumers should pay attention to the place of production, manufacturer and so on when purchasing the pneumatic lifting rod for swing chair. When purchasing the pneumatic lifting rod for swing chair, manufacturers should pay attention to the skill, strength, promise and application materials of manufacturers, the filled gas is in order to maintain the interests and personal safety of the users.
So, what should swing chair manufacturers and users pay attention to in the process of purchasing and using pneumatic lifting rods? As a manufacturer, we propose the following suggestions to our customers:
1) what gas is filled with pneumatic lifting rod?
The pneumatic lifting rod is filled with high-purity nitrogen with a pressure of 6 ~ 8Mpa. It is well known that nitrogen is a stable gas, which can prevent the internal parts of the pneumatic lifting rod from rusting to reach a longer service life, not to mention explosion due to static electricity and conflicts. In order to reduce costs, some companies will be in danger of blasting if they do not fill nitrogen or do not meet the requirements of pressure control.

2) do not disassemble the inner core of pneumatic lifting rod without permission
Some manufacturers of swing chair may disassemble and check the wall thickness of the inner core of the pneumatic lifting rod and the raw materials and strength of the used accessories. In this case, it is best to drill a small hole first and drain the high-pressure nitrogen, it is concluded that the piston rod can be pulled back and forth in the axial direction by hand, and the control button will no longer bounce up before it can be removed.
3) request for wall thickness of inner core of pneumatic Rod lifting rod
Traditionally, the thickness is usually 2mm or 2.5mm. Due to the fierce competition in shopping malls, many manufacturers become thinner and thinner,
The 1.5mm wall thickness has been tested repeatedly by our NJXD science and technology professionals, and its strength can reach the request. However, if it is thinner, there may be doubts such as blasting, which we advocate to use.

4) when we got off work, we lowered the swing chair to the lowest level, and the next morning we found it raised
This kind of scene is called internal leakage, also called "return air", which is one of the quality questions of pneumatic lifting rod.
5) the swing chair will never rise after sitting down
If it is concluded that there is no doubt about the control handle of the chassis, it must be that the pneumatic lifting rod is broken, which is now called external leakage, or "air leakage" for short ".
6) is the grease in the inner core of the pneumatic lifting rod leaking oil?
When the pneumatic lifting rod moves up and down, there will be some grease on the inner core. It helps the inner core and the outer tube slide smoothly without affecting the function, but it will affect the beauty. Many users think that it leaks oil, this is a misunderstanding.
7) many merchants will ask: how many people can the pneumatic lifting rod accept?
A qualified pneumatic lifting rod can accept the weight of anyone without invalidation. However, because it is a pneumatic commodity, the larger the weight of human body, the greater the tightening of pneumatic lifting rod.

8) in a big fire, the lifting rod was burned beyond recognition. Will the pneumatic lifting rod explode?
The pneumatic lifting rod will not burst, because when it is under too high temperature, the rubber seal will be damaged, and the air will leak out, so it will not burst.
