Abstract:Pressure gauge is an instrument used to measure fluid pressure, which is one of the important process parameters in industrial production. If the pressure does not meet the requirements, it will not only affect production efficiency, reduce product quality, but also cause serious safety accidents. Therefore, pressure measurement holds a special position in industrial production. The article introduces the important role and use of pressure instruments for everyone to understand.

Pressure is one of the important process parameters in industrial production. If the pressure does not meet the requirements, it will not only affect production efficiency, reduce product quality, but also cause serious safety accidents. Therefore, pressure measurement holds a special position in industrial production.

The correct use of pressure gauges, accurate measurement of pressure values, and mastery of the correct use of pressure gauges are quite necessary.

The inherent danger of pressure instruments is very low, especially compared to the production systems they monitor, their danger is almost negligible. The reason why the use of pressure instruments needs to be highly valued is that pressure instruments are the prerequisite for automatic interlocking devices, sensing devices, and protective devices, and are the way for various reaction devices to obtain pressure information.

The role of pressure instruments in production systems and the subtle issues that may arise during their operation can be safety hazards, especially for pressure instruments used for monitoring harmful substances such as flammable, explosive, corrosive, and toxic substances. Once there is an error in pressure measurement, it may directly lead to the leakage of harmful substances, causing a huge environmental disaster. The safe use of pressure instruments is not only the responsibility of every enterprise, but also the obligation of every operator. This requires the use of pressure instruments by enterprises to fundamentally improve the safety of pressure instrument use, reduce the occurrence of safety hazards in the system, and provide a good environment for the use of pressure instruments. Worry free spare parts website provides imported pressure instruments, welcome to purchase.

The user unit of pressure instruments should actively carry out the calibration work of pressure instruments on the basis of daily maintenance and testing, timely eliminate, downgrade, and scrap those pressure instruments that do not meet the usage requirements, and ensure that the displayed values of pressure instruments are accurate and reliable. Enterprises using pressure instruments should also establish supervision departments to supervise the departments using pressure instruments and reduce the occurrence of violations. The safe operation of pressure instruments is a long-term and continuous work. The user must start from the system, details, and foundation, avoid illegal operation and prohibit illegal use, fundamentally create a safe environment for the use of pressure instruments, and jointly build a solid safety embankment.

Pressure instruments are commonly used mechanical equipment in industrial control and measurement processes. Pressure instruments can be divided into mechanical pressure instruments and electronic pressure instruments. Among them, mechanical pressure instruments are highly favored by users due to their excellent elastic components and high mechanical strength, and are widely used in industrial production.

The working principle of mechanical pressure gauges is to indicate pressure values through elastic deformation of internal elastic sensitive elements under pressure. Mechanical pressure gauges generally use spring tubes, diaphragms, bellows, and bellows as elastic elements. After deformation, these elastic elements will be amplified by the gear transmission mechanism to display the corresponding pressure values.

The pressure measured by a pressure gauge is generally relative pressure, which is measured with atmospheric pressure as the relative point. The result displayed by the pressure gauge is also the pressure exhibited by the measured object under atmospheric pressure conditions. Pressure gauges are indicated by pointers within the measurement range, and the dial corresponding to the pointer is generally 270 degrees.
