Application of vacuum system in strong acid environment text: the vacuum system installed for a chemical enterprise has been running safely in hydrochloric acid gas environment for a period of time, creating good vacuum production conditions for the enterprise, and the product quality has been recognized.
Vacuum system is mainly used to avoid oil contamination of the pumped medium and vacuum environment, such as some chemical, pharmaceutical and semiconductor industries. The vacuum environment required by the flame retardant production enterprise needs high cleanliness, and the extracted gas needs to be reused to avoid oil pollution. Therefore, the vacuum system is installed for the production.
In the actual production environment, the vacuum system required by the enterprise is in contact with a large number of hydrochloric acid gas, which is highly corrosive, and has quite high requirements for the anti-corrosion performance of the vacuum pump. Therefore, in the process of setting up the vacuum system, the coating of vacuum pump was specially treated. The nano nickel and molybdenum double-layer coating was adopted, and the standard functions such as sealing pressure protection, shutdown cleaning and purging protection were provided to ensure that the vacuum pump can still effectively slow down the corrosion process, extend the service life of the equipment, and ensure the operation and efficiency of the equipment under the strong acid environment.
