Vacuum pumps play a vital role in the field of heritage preservation, and their applications are wide and efficient, which is reflected in the following key areas:

1.Preservation of fragile artefacts: Vacuum pumps play an important role in the treatment of newly unearthed wooden artefacts, and by employing special vacuum treatment technology, they contribute to the long-term preservation of these precious artefacts.

2.Conservation of underwater artefacts: For wooden artefacts excavated from the underwater environment, vacuum technology can simulate the protective effect of water, effectively preventing the decay and decomposition of wood by maintaining its moist state.

3.Wax sealing stabilization treatment: Combined with vacuum pump and low temperature conditions, the direct sublimation of water in the frozen state can be realized, that is, from solid ice to water vapor, avoiding re-liquefaction, so as to realize the drying and stabilization of cultural relics.

4.Desalination treatment of iron cultural relics: In the protection of iron cultural relics, the vacuum pump discharges the air in the void of the cultural relics by vacuuming, so that the desalination solution is easier to penetrate into the cultural relics, thereby improving the desalination efficiency.

5.Non-destructive monitoring of ferrous cultural relics desalination device: This device is specially designed for ferrous cultural relics, which can provide the maximum vacuum while realizing the dynamic monitoring of the desalination solution to prevent excessive desalination from causing damage to cultural relics.

6.Vacuum technology for museum cultural relics display: Vacuum technology can effectively slow down or prevent the oxidation and corrosion process of cultural relics by creating a low-oxygen and low-humidity environment, providing a cleaner and more stable preservation environment for cultural relics.

7.Rapid pumping and nitrogen filling device: This device can quickly reduce the oxygen concentration in the cultural preservation space, create a low-oxygen clean environment, effectively isolate the oxidative pollution of oxygen and pollutants in the air to the unearthed cultural relics, and realize the emergency protection of the unearthed cultural relics.

The role of vacuum pump in the protection of cultural relics cannot be underestimated, it is not only crucial for the long-term preservation of cultural relics, but also provides strong technical support in the process of display and protection of cultural relics, ensuring the safety and integrity of cultural relics.
