Operating principle of NJXD pneumatic lifting rod
The NJXD pneumatic lifting rod determines the thrust and pulling force on the piston rod according to the force required for work. Therefore, when selecting the pneumatic lifting rod, the output force of the cylinder should be slightly surplus. If the cylinder diameter is small and the output force is not enough, the pneumatic lifting rod cannot work normally; However, the cylinder diameter is too large, which not only makes the equipment bulky and Cheng Bengao, but also increases the gas consumption, resulting in energy waste. In the fixture design, the booster mechanism should be used as much as possible to reduce the size of pneumatic lifting rod.
The following is the calculation formula of the theoretical output of the NJXD pneumatic lifting rod:
F: theoretical output force of pneumatic lifting rod (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 working pressure of the pneumatic lifting rod with a diameter of 340mm is 3kgf/cm2, what is its theoretical output force? What is the Bud output force?
Connect P and D, find the points on F and f', and get:
F=2800kgf;F′=2300kgf
In engineering design, the cylinder diameter of pneumatic lifting rod can be selected from Empirical Table 1-1 according to its applied pressure and theoretical thrust or tension.

Example: there is a pneumatic lifting rod whose operating pressure is 5kgf/cm2, and its thrust is 132kgf when the cylinder is pushed out, (the cylinder efficiency is 85%) Q: What is the cylinder diameter to choose?
● The theoretical thrust of the cylinder can be calculated as F = f'/85% = 155(kgf) based on the thrust 132kgf of the pneumatic lifting rod of Xuedian NJXD and the efficiency 85% of the cylinder.
● by using the pressure of 5kgf/cm2 and the theoretical thrust of pneumatic lifting rod, finding out the cylinder with cylinder diameter of 63 can meet the use requirements.

Advantages of Nanjing Xuedian pneumatic lifting rod compared with traditional pneumatic lifting rod
1) the pneumatic lifting rod can work independently, without pulling rope, it can work stably under the wind speed of 20 m/s, without damage under the wind speed of 35 m/s, which greatly reduces the requirements for use, and can save manpower to the greatest extent;
2) the rod body of pneumatic lifting rod adopts square section. In the same installation space, square section can provide higher strength, rigidity, torsion resistance and bending resistance;
3) the rod body of the pneumatic lifting rod is made of refined aluminum alloy material, and the drawing process and precision are far beyond the national standard;
4) the movement indirect contact between the rod body and the rod body of the pneumatic lifting rod ensures the anti-corrosion ability of the surface of the rod body;
5) the rising and falling of the rod body of the pneumatic lifting rod are linked, and there is no frequent locking and unlocking process in the process of rising and falling of the rod body one by one;
6) The pneumatic lifting rod is self-locking relying on T-shaped screw bar, which can lock at any height and direction and keep stable operation;
7) the lifting action of the pneumatic lifting rod is driven by power, and it can also fall smoothly under no load, which can ensure the reliable lifting work of the system in harsh environment;
8) all the transmission systems of the pneumatic lifting rod are closed, and there is a rubber RS between the rod body and the rod body to seal (this RS is a life piece, but it is easy to replace and has low cost), good waterproof and sand-proof performance and strong anti-corrosion capability;
9) the design life of pneumatic lifting rod products is 20 years, with simple maintenance and high reliability. Pneumatic lifting rod products have sufficient safety factor (all products are tested 100% before leaving the factory, the bearing capacity of the product can reach about 1.5 times of the nominal bearing capacity before leaving the factory);
10) the company has strong design and calculation ability, and can provide various safety performance calculation data of the rod body of the pneumatic lifting rod (the safety of the vehicle or the cabin is not included);
11) the pneumatic lifting rod products have passed the environmental test (mold, salt spray, damp-heat alternating, high and low temperature work, high and low temperature storage, vibration, rain, sports car test, etc.) conforming to the national military standard gjb150;
12) compared with the same type of foreign products, Xuedian pneumatic lifting rod has a higher price-performance ratio.
