防爆電氣設備零件安裝原則

組件配置後, it’s essential to choose an installation method that aligns with their structural features, 始終遵循這些基本準則:

1. 裝置內部, 元件安裝面板 (或一塊) 應配備四個安裝孔以確保牢固安裝. It’s vital that no loosening occurs during the equipment’s operation.

2. In assemblies utilizing bolt (or screw) and nut connections, the inclusion of spring washers (65Mn) is mandatory. When fastening, ensure the spring washer is compressed just enough to flatten, avoiding over-tightening. Overly aggressive tightening over extended periods can lead to the loss of elasticity in the washer.

3. In instances where bolts and nuts are attached to non-metallic parts, flat washers must be placed between the spring washer and the base to prevent direct compression. Applying direct pressure from the spring washer onto the base can result in surface scratches and damage to its integrity.
