Japanese torsion spring 90 degrees

The 90 degree torsion spring is a free state torsion Angle at the 90 degree position, the spring produces torque or rotational force. The ends of the torsional springs are secured to the other components, which pull them back to their starting position as they rotate around the center of the spring. Although the spring is called a torsional spring, it is subject to bending rather than torsional stresses. Torsional springs can store and release angular energy or hold a device statically by rotating a moment arm around the central axis of the spring body. This type of spring is usually tightly wound, but the pitch between the springs reduces friction. They create resistance to rotational or rotating forces. Depending on the application, torsion springs can be designed to turn clockwise or counterclockwise to determine the turn direction of the spring.

Network optimization materials:

1 Check the zero range. It shall comply with the provisions of Article 7 of this procedure.

The range measurement verification of barometer is carried out according to the measuring range line of the marked data (including zero value). Professional high temperature spring measurement verification, slowly change pressure (or empty), when the range to measure the limit, pressure resistance 3min; The barometer that has been welded again by electric welding of the elastic yellow tube should be subjected to pressure resistance at the measuring limit for 10min, and then be checked back by lowering blood pressure at the original measuring point.

The difference between the measuring range of the watch case and the measuring range of the normator shall comply with the requirements of Article 8 of this regulation.

The difference between the reading value after the tap during the pressure change and the reading value after the tap during the pressure change and the reading value after the tap during the blood pressure drop at the same measuring point at all measuring points shall meet the requirements of Article 9 of this procedure.

The change of hand range caused by tapping the watch case strap (including zero value) shall comply with the requirements of Article 10 of this regulation.

When carrying out range measurement verification, it is necessary to check the stability of the moving hand, and it should comply with the requirements of Article 11 of this regulation.

When the negative pressure gauge is used, the working pressure of the spring of the professional high-temperature mold is verified according to the measuring range line marked with the data.

One part of the vacuum pump: three points when the upper limit of measurement is 0.06MPa; When the upper limit of measurement is 0.15MPa, check two points.

When measuring the working pressure negative gauge with the upper limit of 0.3 to 2.4MPa, the gauge finger should be tilted to part of the vacuum pump during vacuuming.

5. The negative pressure gauge shall carry out pressure measurement verification according to the void opening degree above 90% of the standard air pressure in the region.
