There are usually high -pressure environments in the production of chemical products, while the pressure instrument can monitor environmental pressure and visually display it on the dashboard in a numerical manner. During the high pressure link, the pressure instrument can ensure the safety of the construction personnel and the safety of production work. In high -pressure environments, the common faults in the existence of pressure instruments include: (1) The pressure value parameter of the pressure instrument equipment is wrong. When the pressure instrument equipment fails, the parameter error occurs. This situation will cause safety accidents such as toxic items and personnel casualties. (2) The sealing of the pressure instrument is invalid. When the pressure instrument is aging, the pressure instrument will decrease, which will cause the pressure instrument parameters to read abnormalities. (3) The pressure instrument equipment is aging, the circulation pipeline is blocked, which will cause system failure. One of the main reasons for the operation failure of the pressure instrument.
1.3 Dalm level instrument system failure
In the production process of chemical products, the production equipment liquid level instrument monitoring system and data transmission and analysis system have a certain impact on the production efficiency, production cycle, production supervision, etc., and the implementation of chemical production management plans. If the liquid level instrumental equipment of chemical production equipment fails, it will not only cause the quality and production efficiency of chemical products, but also damage the liquid level instrument equipment, which will also cause harmful substances and toxic gases, which will cause damage to production equipment. In addition, the common causes of liquid level instruments in the production process of chemical products mainly include equipment failure, equipment leakage, pipe leakage, etc. The above situations will cause errors in the reading of liquid level instrument parameters. If the problem of liquid level instrument failure occurs during the production of chemical products, it will not only greatly affect the stability and safety of production, but also environmental pollution and corporate economic and social benefits.
