What material is generally used for the window part of the Aluminium Oil Level Sight Glass? How to ensure oil resistance and corrosion resistance?

The explosion-proof ability of the Aluminium Oil Level Sight Glass mainly depends on its material properties and structural design. Aluminum alloy itself has high strength and toughness, and is more impact-resistant than glass sight glasses. It can withstand certain pressure fluctuations, thereby reducing the risk of bursting caused by sudden pressure increase or external impact. In terms of structural design, high-quality Aluminium Oil Level Sight Glasses usually adopt a high-pressure sealing structure, such as fluororubber or nitrile rubber sealing rings, so that it can withstand a working pressure of 1.0MPa to 4.0MPa, effectively reducing the safety hazards caused by medium leakage.

Some high-end models will also pass international explosion-proof certification to ensure safe use in flammable and explosive environments. However, if the observation window part of the sight glass still uses ordinary glass, its overall explosion-proof performance will be limited. Therefore, it is recommended to use explosion-proof glass or polycarbonate as the observation window material in high-risk scenarios.

The Aluminium Oil Level Sight Glass has excellent seismic resistance, mainly due to the natural toughness and mechanical vibration resistance of aluminum alloy materials. Compared with glass or plastic sight glasses, aluminum sight glasses are less likely to crack or deform in long-term vibration environments (such as generators, construction machinery or marine equipment).

Some products also use anti-vibration optimization designs, such as adding elastic gaskets, shock-absorbing flanges or anti-loosening bolts to further reduce the impact of vibration. If the sight glass includes a glass observation window, the manufacturer may use sandwich reinforcement or high-strength bonding processes to enhance its stability in a vibrating environment. However, in extreme high-frequency vibration situations, customized designs may be required to ensure long-term reliability.

In order to ensure the safe use of Aluminium Oil Level Sight Glasses in harsh environments, users should take targeted measures during selection and installation. In terms of explosion protection, give priority to all-metal enclosed structures or observation window materials with explosion-proof certification, and ensure that the product meets relevant industry standards. In terms of earthquake resistance, products with one-piece molding design should be selected to reduce potential weaknesses in joints, and anti-loosening gaskets should be used during installation or the status of fasteners should be checked regularly. In addition, avoiding overpressure or overtemperature operation and regularly maintaining seals can greatly extend the service life of the sight glass and reduce the risk of failure.
