What is a qualified pressure gauge movement

Pressure gauge movement structure

The composition of the pressure gauge movement consists of the shaft gear angle, the transmission balance, and the hairspring. For the pressure gauge, the transmission accuracy of the pressure gauge movement will directly affect the accuracy of the instrument, so there are certain requirements for the pressure gauge movement.

Pressure gauge movement requirements

1. Pressure gauge movement: When the pressure gauge movement is rotated, the rotation angle of the shaft gear should not be less than 360 degrees.

When the gear rotates 360 degrees, the number of teeth that the sector gear does not engage should not be less than three.

2, pressure gauge movement transmission balance: pressure gauge movement gear transmission, should be smooth and flexible, there should be no jumping and stop now

Elephant.

3, pressure gauge movement spring: When the pressure gauge movement is placed horizontally, the hairspring should be in a horizontal state. The pitch of the hairspring should be even,

The connection between the hairspring and the pillar should be firm.

4, pressure gauge movement appearance: the surface of the pressure gauge movement should be clean, no smudges and obvious burrs and other defects.

Pressure gauge movement spring

The hairspring is part of the movement of the pressure gauge. The movement is the component of the pressure gauge at the center of the pressure gauge. The statement of the pressure gauge is not accurate. It should be called the movement spring. The movement spring acts as a small spring. During the operation of the watch, the pointer of the pressure gauge can be stabilized and the reading of the pressure gauge can be accurately displayed.
