Explosion -proof switches are widely used in high -risk industries such as petroleum, chemical industry, and electricity. In the face of high temperature, high humidity, vibration and other complex environments, they need to have excellent earthquake resistance, waterproof, and corrosion resistance to ensure the safety of the equipment. The explosion -proof and sealing technology is an effective means to protect the explosion -proof switch from being affected by external environment. Papering can not only provide additional mechanical protection, but also effectively prevent internal components from moisture and corrosion, avoid poor electrical contact and other problems, and ensure the stable work of explosion -proof switches in harsh environments.
However, the sealing demand of explosion -proof switches is challenging, especially in the choice of glue’s liquidity, bottom sealing, and solidifying method.
Explosion-proof switch
challenge
When choosing an irrigation material for explosion -proof switches, the design team is facing the following challenges:
Moderate liquidity of glue: The irrigation sealing needs to have good liquidity in order to penetrate into every corner of the switch and ensure that each contact point is fully covered. However, over -flowing glue can cause the glue to penetrate into a area where it should not be penetrated, which will affect the performance of the switch.
The bottom sealing: The explosion -proof switch is often facing the risk of glue from the bottom during the sealing process, especially before solidification. Therefore, ensuring the sealing of the bottom is another key issue. If the bottom leakage is leak, it may cause incomplete seal effect and even affect the security of the switch.
Normal temperature curing: In many industrial applications, explosion -proof switches may require irrigation operations without high temperature equipment. Therefore, it is particularly important to choose an irrigation and sealing that can be solidified at room temperature.
