Printer Shaft

What are the main features of the inflation shaft?

1: The inflating operation time is short, the separation and placement of the inflation shaft and the paper tube can be completed in 3 seconds to complete the inflation and deflation, and it is not necessary to separate any parts on the shaft end side to be tightly engaged with the paper tube.
2: The paper tube is simply placed: in the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
3: The bearing weight is large: the diameter of the shaft can be determined according to the actual needs of the customer, and the high-hardness steel is used to make the bearing weight increase.
4: High economic efficiency: The shaft is designed for special functions, and can be applied to all kinds of paper tubes of thick, thin, wide and narrow.
5: Simple maintenance and long use time: The inflation shaft is a single part, and each part in the structure has fixed specifications, which can be used interchangeably to make it easy to maintain.

What are the experimental methods for the abnormal operation of the inflation shaft?

The intent of the abnormal operation experiment is to improve the reliability of the system, and to avoid the incidents that should not be there. Abnormal operation experiments can be carried out as follows:

1. External sudden power failure experiment. When the equipment is operated manually or actively, no matter under any circumstances, the sudden power-off of the external can be suspended, and the normal operation process can make the equipment recover.


2. Emergency breaking experiment. When the equipment is running manually or actively, no matter what the circumstances, regarding the emergency breaking operation (such as pressing the emergency stop button on the control panel), the equipment can be suspended and the normal operation can be resumed after regular operation. .


3. Detect switch failure experiments. Consideration should be given to the possibility of system detection switch failure, especially for components that are prone to collisions, dryness, and safety of mechanical components, and abnormal tests for signals such as end-of-stroke detection. It is necessary to ensure that even if a certain detection switch is defective or damaged, There will still be no security incidents.


4. Perform no residual experiments. Consideration should be given to the possibility of the system performing flawlessness, especially regarding the implementation of parts that are prone to mechanical bumps, dryness, and affecting safety. It is necessary to carry out abnormal experiments. It is necessary to ensure that even if a certain performance component is damaged or damaged, it still does not There will be security incidents.


5. Maintenance loop action experiment. Consideration should be given to the possibility of system maintenance circuit operation, especially for maintenance devices such as circuit breakers and active switches. It is necessary to carry out abnormal experiments. It is necessary to ensure that when the maintenance device operates, the equipment can be suspended and the rules are followed. Can recover from normal work.

The inflation shaft manufacturer tells you the cause for the gas leakage

1. the hose breaks, perhaps there is a excellent trouble within the hose itself. it is important to dispose of the shaft head and update it with a hose.

2. the seal ring offers a gap, which calls for sealing within the sealant

3. the stress ring is loose, just tighten the stress ring, pay attention to the usual investigation to see if it is unfastened.

4. the fuel-filled mouth part leaks, after which it may be replaced and replaced.
