How to solve the problem of fire extinguisher pressure gauge pointer stuck

In industrial applications, fire extinguisher fire extinguisher pressure gauges are key measuring tools, and their accuracy and reliability directly affect the safety and efficiency of the production process. However, the phenomenon of the fire extinguisher pressure gauge pointer getting stuck and not moving often occurs, which not only affects the normal operation of the equipment, but may also cause production accidents. Therefore, it is particularly important to investigate and solve this problem.

First of all, one of the main reasons for the fire extinguisher pressure gauge pointer getting stuck may be the winding of the hairspring. The winding of the hairspring usually comes from the fire extinguisher pressure gauge being improperly adjusted or being affected by vibration during transportation. When the hairspring is hung on the nut, the fire extinguisher pressure gauge may have a "jumping needle" failure during operation; and if the hairspring is wound on the fan teeth, it will cause the fan teeth and the center axis teeth to entangle with each other, so that the pointer cannot rotate freely. To solve this problem, it is necessary to disassemble the watch cover, remove the dial for detailed inspection, and re-adjust the position of the hairspring to ensure that it will not entangle with key components such as the fan teeth.

Another common cause of failure is the eccentric movement of the dial and the bending of the center axis of the movement. In this case, the pointer may rub against the inner hole of the dial during operation, and in severe cases, the pointer may be completely stuck. In order to solve this problem, the position of the dial must be adjusted to ensure that it is concentric with the center axis of the movement. At the same time, the state of the center axis of the movement must be checked. If bending is found, it must be replaced or repaired in time to restore its normal function.

In addition, the pointer may also get stuck if the needle is too high. When the needle is too high, the watch glass may press the needle library and hinder the normal movement of the pointer. At this time, you can check the operation of the pointer by loosening the cover and removing the watch glass. If the pointer can return to normal, it means that the problem is indeed caused by improper needle height. At this time, the height of the needle needs to be adjusted to ensure that it is within the normal range.

In addition to internal faults, external factors are also an important reason for the fire extinguisher pressure gauge pointer to get stuck. For example, the valve under the fire extinguisher pressure gauge is not opened or the pressure guide hole is blocked, which will cause the pointer to be unable to move. When the valve is not opened, the fire extinguisher pressure gauge pointer naturally cannot respond when pressurized. The solution is to slowly open the valve to restore the normal state. If the pressure guide hole is blocked, it needs to be cleaned to ensure that the pressure can be smoothly transmitted to the inside of the fire extinguisher pressure gauge.

When dealing with a stuck fire extinguisher pressure gauge, operators need to pay special attention to the following points: First, be sure to follow the fire extinguisher pressure gauge's instruction manual and safety specifications to avoid further damage to the equipment during operation. Second, if you are unable to determine the root cause of the problem or resolve it yourself, it is recommended that you contact a professional fire extinguisher pressure gauge repairer or manufacturer for repair in a timely manner. In addition, regular inspection and maintenance of the fire extinguisher pressure gauge is also an important measure to ensure that it is in good working condition.
