Structure description:
The compensating micro pressure gauge system consists of a fine-tuning part, a leveling observation part, a reflector part, and a housing part
The compensating micro pressure gauge system consists of a fine-tuning part, a leveling observation part, a reflector part, and a housing part
1. Fine adjustment section - consisting of a fine adjustment disc engraved with 200 equal parts, fixed on a long screw. When the long screw moves, the water box moves up or down, and a gauge block is installed on the static pressure of the water box and the nozzle. The gauge block moves to a height between the gauge plate and the character plate.
2. Leveling observation section - equipped with a water level head inside the observation cylinder to observe changes in the liquid inside the cylinder after dynamic pressure.
3. Reflective mirror part - fixed on the mirror shell by a reflective mirror, the reflective mirror reflects the contact between the water level head and the liquid surface in the observation cylinder, so that the tip of the water level head is connected to the shadow tip of its reflection, and the reading adjustment base point of the micro pressure gauge is adjusted.
4. Shell part - supported by the shell and crossbeam, the long screw is equipped with level bubbles and adjustment screws on the shell rod to adjust the verticality of the screw and dynamic pressure tube of the micro pressure gauge.
