Why Is The Air Expanded Shaft Lug Tip Inflated With Insufficient Inflationary Pressure?

The air expansion shaft is powered by high-pressure gas, and the shaft with a convex surface is controlled by inflation and degassing, so as to realize the surface expansion and tension control of the shaft.
The use of inflatable shaft and inflatable sleeve is very convenient and fast, this inflatable shaft only needs the user to provide their own air source, and the air pressure of the inflatable shaft is controlled in the range of 6-8kg.

Causes of insufficient inflation pressure at the tip of the inflatable shaft lug:
First of all, it may be because the tip of the inflatable shaft lug has accumulated too much impurities during use, causing the gas flow to be blocked. At this time, we can solve this problem by cleaning the lug tip.
In addition, it is also possible that the air supply is due to the air supply, especially when the air pressure is too low or unstable, which will cause the inflation pressure of the inflatable shaft lug to be insufficient. At this point, we need to adjust or replace the air supply.
There is also the possibility that there is insufficient inflation pressure due to the defect of the inflatable shaft lug itself. In this case, the lugs need to be inspected and repaired.

The solution when the inflation pressure at the tip of the inflatable shaft lug is insufficient:
1) Check that the inflation valve of the inflatable shaft is completely closed. If the valve is not closed, air will flow out of the shaft, resulting in insufficient inflation pressure. Make sure the inflation valve is closed after inflation.
2) Check if there is any damage or defect between the inflatable shaft and the bushing. If so, it needs to be replaced in time. And when replacing an inflatable shaft or bushing, make sure they are a perfect fit, durable, and code-compliant.
3) Soak the shaft in water and check for air bubbles on the shaft body. If air bubbles appear on the surface of the shaft, it indicates a leak in the inflatable shaft. In this case, the shaft body needs to be replaced.
4) Make sure there is sufficient lubrication between the inflatable shaft and the bushing. The right amount of lubricant can help reduce friction and extend the life of an inflatable shaft.
5) Regular maintenance of the inflatable shaft is the best way to prevent insufficient inflation pressure at the tip of the inflatable shaft lug. After each use, wipe the inflatable shaft clean and keep it properly to avoid hard objects and dust from entering the inflatable shaft.
6) Check whether the air pressure is too low or unstable.

Installation steps for convex key inflatable shaft (key bar inflatable shaft) and through-length key inflatable shaft:
1) When installing the air expansion shaft, it is necessary to make sure that the compressor that controls the gas pressure is in a stable state, and the filter is directly installed between the compressor and the expansion shaft to prevent impurities from blocking the air pipe and causing air leakage.
2) Air should enter vertically to prevent damage to the valve;
3) When venting exhaust gas from a key key type inflatable shaft (inflatable shaft of the key lever), a standard exhaust port must be used. The use of sharp hammers and other tools is prohibited. Avoid causing air leakage;
4) Install pressure gauge and pressure control device, and the pressure must be controlled within the range of 3-8kg/cm;
5) When replacing the valve of the convex key inflatable shaft (main rod inflatable shaft), a socket wrench must be used. If an internal failure occurs, it needs to be disassembled and repaired, please consult professional maintenance personnel, do not disassemble, so as not to cause unnecessary losses;
6) The convex key inflatable shaft (key rod inflatable shaft) should be placed carefully to avoid damaging the air valve.

Features of plate type inflatable shaft/Leaf Type Pneumatic Shaft:
The tile type inflatable shaft is made of aluminum alloy tiles, flexible expansion and contraction, equipped with high-quality rubber liner and fast filling and exhaust nozzle, good sealing effect, long service life, detachable shaft head, easy maintenance. After inflation, the expansion part is a plate, usually the expansion height can reach 4-5 mm (such as 74 to 75 mm diameter before expansion, 78 to 79 mm diameter after expansion), special expansion height, separately required, 3-inch plate type inflatable shaft, usually use the inner diameter of the coil tube is 76 mm.

Fields of application of shingle inflatable shaft:
The tile type inflatable shaft expands the whole plate, the fulcrum is evenly dispersed, and the force is uniform, which can be applied to machinery with high winding precision or lighter winding items, such as: electronic materials, battery materials, foam, plush, paper products, non-woven fabrics, etc. It is suitable for coating, slitting, printing, rewinding, laminating, papermaking, bag-making, plastic and other related machinery reeling and unwinding reels, especially suitable for paper tubes with high roundness requirements or the use of surface rewinding and unwinding occasions, which can effectively improve work efficiency and product quality
When ordering the inflatable shaft, the user must specify the type and dimensions of the inflatable shaft, mark the tolerances of the important dimensions on the shaft, and indicate the special requirements.

Precautions for custom plate inflatable shafts:
When ordering the inflatable shaft, the user must specify the type and dimensions of the inflatable shaft, mark the tolerances of the important dimensions on the shaft, and indicate the special requirements.
