Pressure gauge pointer is bent
The pressure gauge has been used for a period of time, but the pressure of the gauge is unstable, or the pressure gauge is removed for maintenance. Sometimes you will find that the pointer to the original straight sword has become a machete shape, and a small depression will obviously be left at the "retreat" The size of the mark or depression, the pointer is bending.
The pressure gauge bends the pointer of the pressure gauge, which is relatively lower than the "bend" of the nail. This is because the pressure gauge releases pressure too quickly and too quickly during work, causing the pointer to repeatedly hit the nail plate for inspection. This is usually at the lower pointer of the pressure gauge, and check the position of the pointer and the stylus. It can be seen that the impact of severe impact will leave the depth of the gap.
The relative pressure check dial "returns" to the bent nail. This is because the pressure gauge is used, the pressure is too large, the pressure gauge pointer is counterclockwise to check the steering wheel too quickly, and the nail bending has a greater impact. It also leaves a gap on the upper side of the pressure gauge pointer.
The material of the pressure gauge pointer is generally an aluminum alloy plate. If the material of the pressure gauge pointer is too thin and the material is too soft, the reason is that the pressure gauge pointer is easy to bend.
