When disassembling the convex key inflatable shaft, the following steps should be followed:
1. First, press the steel head of the inflation nozzle on the inflation shaft to release the compressed air inside the inflation shaft;
2. Remove the inflation nozzle;
3. Use iron wire to pass through the small holes on the key strip along the circumference of the inflation axis, with a group of holes in the same circumferential direction;
4. Secure all key strips to prevent them from falling into the aluminum alloy roller when the airbag is pulled out, making it easy to install the airbag;
5. Remove the positioning screws and sleeves that fix the aluminum alloy roller and gas expansion shaft at both ends;
Convex key inflation shaft: also known as key type inflation shaft, key bar type inflation shaft, etc., but the working principle is the same.
Convex key inflatable shaft, key strip inflatable shaft, convex claw inflatable shaft, claw key inflatable shaft, but the working principle is the same. When customizing inflatable shafts, users must indicate the type and external dimensions of the inflatable shaft, mark the tolerance level and order quantity of important dimensions on the shaft. If there are special requirements, they should be specified separately.
Features: The main body of the shaft is made of high-quality steel pipe, with a chrome plated surface and aluminum protruding keys that are flexible in expansion and contraction; Equipped with high-quality rubber inner liner and fast charging and discharging air nozzle, it has good sealing effect, long service life, detachable shaft head, and easy maintenance. After inflation, the single-sided expansion height can reach 5mm to 6mm, for example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 79mm to 82mm. Special expansion heights are required separately. 3-inch key type inflation shaft, usually using a coiled tube with an inner diameter of 76mm.
Applicable: The key type inflatable shaft expands a single key strip, and the fulcrum spreads to each key strip, balancing the force. It can be used for mechanical winding of heavy load-bearing items, such as fabrics, paper products, films, printed materials, leather, composite materials, etc. It is suitable for the winding and unwinding of related machinery such as coating, slitting, printing, rewinding, composite, papermaking, bag making, plastic, etc. It can effectively improve work efficiency.
1. Sudden power-off test on the boundary of the external inflation shaft key rod
When the device is manually or automatically started, regardless of the situation, the external power supply can be reliably terminated and the device can resume operation according to the required steps. Inflatable shaft key rod
2. Emergency Interruption Test
When the equipment is manually or automatically started, regardless of the situation, actual operation (such as pressing the key panel of the emergency stop switch to operate the air expansion shaft) can reliably stop the equipment, and it can resume work according to the required operating steps.
3. Check if the power switch is functioning properly and conduct a test
We should consider the detection probability network of poor power switches, especially mechanical parts, which are susceptible to interference and can easily harm safety components. The key process of solving the gas rising shaft article is to arrange terminal inspection of all data signals of the gas rising shaft key. If abnormal testing is carried out, it is necessary to ensure that even if the power difference is checked, the key of the starting shaft key falls off or the key is damaged or the gas rising shaft is not prone to safety accidents.
4. Conduct infinite imperfect testing
The probability of no defective components in the implementation of system software should be considered, especially for components that are prone to cause mechanical equipment impact, intervention, and safety hazards. To solve test abnormalities, it is necessary to ensure that even if the shaft key rod device is not good or damaged, safety accidents are not likely to occur.
5. Maintenance circuit posture test
The probability of system protection circuit composition should be considered, especially for the maintenance of isolation switches, control system switches, and other devices related to the key strip of the air lift shaft. To solve abnormal tests, it is necessary to ensure that when the key strip protection device of the product constitutes the air lift shaft, the equipment can be terminated according to the spectrum and restored to work according to the operation steps.
