Analysis of Common Faults and Problems of Seismic Pressure Gauges
Fully refined paraffin refers to a product obtained by using oil-containing wax as the raw material, degreased by sweating or solvent, and then refined by clay or hydrogenation.
Fully refined paraffin is also called refined white wax. The appearance of fully refined paraffin is white solid, with block and granular products. Its product has a higher melting point, less oil content, no sticking at room temperature, no sweating, no greasy feeling, waterproof, moisture-proof It has good electrical insulation. Because of its high degree of sophistication and low content of fused aromatic hydrocarbons. It has good chemical stability and light, good thermal stability, strong toughness, good plasticity, white color, no mechanical impurities and moisture, and no smell. Fully refined paraffin can be Soluble in: benzene, ether, chloroform, carbon disulfide, carbon tetrachloride, turpentine, petroleum, fixed oils.
Mainly used in high-frequency porcelain, carbon paper, stylus wax paper, precision casting, decorative sound-absorbing board and other products. Also used in packaging, electronics, textile candle crayons, match making and other industries. In addition, manufacturing high-grade candles and various industrial, civilian candle products Raw materials and additives, modifiers, etc.

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, the spring pipe joints within the excessive fouling and 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-proof pressure gauge pointer jump or sluggish phenomenon: 1, the pointer and the surface of the glass or scale touch Capricorn; 2, the central gear shaft bending; 3, two gear mesh with dirt; 4, connecting rod and fan gear The activity screws are 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 pressure gauge indication is low: 1. The gear ratio is out of adjustment; 2. The spring tube has leakage; 3. The pointer or transmission mechanism has a friction element; 4. The pressure guiding pipeline is leaked. Eight, shock pressure gauge pointer can not be indicated to the upper limit scale: 1, the transmission ratio is small; 2, the movement of the fixed position in the base is not appropriate; 3, the wrong position of the spring tube welding.
