Shock pressure gauge common faults and their causes First, shock-proof pressure gauge pointer jitter: 1, measured medium pressure; 2, pressure gauge installation location vibration. Second, the earthquake pressure gauge without instructions: 1, the pressure tube on the shut-off valve is not open; 2, pressure tube blockage; 3, spring pipe joints within the fouling and excessive fouling; 4, spring pipe cracking; 5, The center tooth and the sector tooth wear too much to mesh. Third, the pressure gauge pressure indication error inhomogeneity: 1, spring tube deformation failure; 2, spring tube free end and sector gear, connecting rod transmission ratio is not properly adjusted. Fourth, shock pressure gauges common faults and causes analysis Seismic pressure gauge pointer jump or sluggish phenomenon: 1, the pointer and the surface of the glass or scale touch Capricorn; 2, the center gear shaft bending; 3, the two gear mesh with dirt ; 4, the link between the activities of screws and fan gear is not flexible. 5. When the pressure of the pressure gauge is removed, the pointer cannot be restored to zero: 1. The pointer is bent; 2. The spring force is short; 3. The pointer is loose; 4. The transmission gear has a friction. Sixth, the transmission ratio is misaligned. Seventh, the earthquake pressure gauge indicates the low: 1st, the gear ratio is misadjusted; 2nd, the spring tube has the leakage; 3, the pointer or the transmission mechanism has the friction pole; 4ã€The pressure guiding pipeline has the leakage. Eight, shock pressure gauge common faults and causes analysis Seismic pressure gauge pointer can not be indicated to the upper scale: 1, the transmission ratio is small; 2, the movement of the fixed position in the base is not appropriate; 3, the spring pipe welding position is not appropriate.
