Pneumatic lifting rod operation principle and development application

Pneumatic lifting rod the thrust and tension on the piston rod should be determined according to the size of the working force, and the output force of the cylinder should be slightly margin when selecting pneumatic lifting rod. If the cylinder diameter is small and the output force is not enough, pneumatic lifting rod will not work normally; However, the cylinder diameter is too large, which not only makes the equipment heavy and costly, but also increases the air consumption, resulting in energy waste. In fixture design, force increasing mechanism should be adopted as much as possible to reduce the size of pneumatic lifting rod.
The formula for calculating the theoretical output of Xuedian NJXD pneumatic lifting rod:
F: pneumatic lifting rod theoretical output force (kgf)
F': output force (kgf) when the efficiency is 85% -- (f' = f×85%)
D: pneumatic lifting rod cylinder diameter (mm)
P: working pressure (kgf/cm2)
Example: when the straight diameter is 340mm and the working pressure is 3kgf/cm2, what is the theoretical output force? What is the Bud output force?
Connect P and D to find the points on F and f', so as:
F=2800kgf;F′=2300kgf
When selecting the cylinder diameter of pneumatic lifting rod/cylinder in engineering design, it can be found out from experience Table 1-1 according to its operating pressure and theoretical thrust or tension.
Example: one pneumatic lifting rod of its operating pressure is 5kgf/cm2, and its thrust is 132kgf when the cylinder is pushed out. (the cylinder efficiency is 85%) question: what cylinder diameter should I choose?
● from the thrust of pneumatic lifting rod 132kgf and the efficiency of the cylinder 85%, the theoretical thrust of the cylinder can be calculated as F = f'/85% = 155(kgf)
● According to the theoretical thrust of using pressure of 5kgf/cm2 and pneumatic lifting rod, find out that the cylinder with cylinder diameter of 63 can meet the application requirements.

Mobile lifting lighting
The main technical problem of mobile lighting lies in moving. To solve this problem, we must first have lift rod products of high quality.
Nanjing Xuedian Lighting Co., Ltd. is engaged in the research and development of pneumatic lifting rod, integrating the most advanced technology in the world, and has made great progress in the field of mobile lighting, the application of pneumatic lifting rod products in mobile lighting is becoming more and more important.
Mobile lighting (emergency light), as a standby mobile standby electric light source, has entered a high-level stage of application research, and its application scope is increasingly wide. It has been widely used in civil, military, earthquake relief, logistics support, emergency response, etc.
The most common application of mobile lighting is the night lighting Stadium and the scene of large singing and dancing parties. You can see the figure of mobile lighting, and the pneumatic lifting rod rises high.

Pneumatic lifting rod application in mobile lighting vehicle
The mobile lighting system of Nanjing Xuedian Lighting Co., Ltd. carries out the following technical measures according to the market demand:
1. Portable: it adopts a lifting (telescopic) design with a maximum height of 30 meters.
2. Rationalization: Segment products according to the needs of the industry, and rationalize the product structure;
3. High efficiency: use special high-efficiency bulbs;
4. Continuity: use "sealed voltage-controlled battery" and corresponding charging methods.
5. Backup: use vehicle-mounted standby power supply.
With the further improvement of technology, the application of mobile lighting technology will be more extensive and the subdivision degree of products will be strengthened, which also puts forward higher requirements for pneumatic lifting rod products.
