Seismic pressure gauge compared with ordinary pressure is what, what is the scope of application
Seismic pressure gauges for environment vibration, the pulse of media tolerance, and the impact of a sudden unloading, the instrument is stable and clear. Widely used in machinery, petroleum, chemical, metallurgy, mining, power and other departments to measure the pressure of copper and copper alloys without corrosive medium.Shock proof pressure meter is composed of pressure leading system (including joint, spring tube, limiting screw), gear transmission mechanism, indicator device (pointer and dial) and the shell (including watchcase, table cover, table glass etc.). Vibration proof pressure gauge shell is airtight type structure, can effectively protect the internal parts from the environmental impact and pollution invasion. Vibration proof pressure gauge filled with damping liquid in the shell (usually silicone oil or glycerin) instrument, ripple resistance to working environment and reduce the vibration of medium pressure. The ordinary pressure gauge has poor seismic performance.
1, advantages: seismic table is mainly applicable to the mechanical pressure and intense vibration occasions, the general seismic table by silicone oil filling (low product charge glycerol) as damping oil to reduce vibration indicator beating effect on detection of pressure, but also to increase the pressure in bad environment of life.2, disadvantages: high prices. Seal is not good, prone to oil leakage phenomenon, there are few domestic enterprises to ensure that products must not leak.Now there is a foreign seismic dry table, by changing the core structure of shock absorber, the effect is good, but the price should be cheaper than domestic oil filled gauge.
Ordinary pressure gauges are suitable for measuring the pressure and vacuum of liquids, gases, or vapors that are free of explosion, crystallization, solidification, and corrosion of copper and copper alloys.Vibration proof pressure gauge is widely used in machinery, petroleum, chemical, metallurgy, mining, electricity and other sectors, measurement of non corrosive medium on copper and copper alloy pressure.Seismic pressure gauge pressure gauge has the advantages compared with ordinary:The utility model is suitable for the environment violent vibration places, and can withstand the pulsation of the medium, the impact and the sudden unloading, and the instrument indication is stable and clear.
