申海防爆
防爆控制箱主要用於控制照明系統配電箱及供電系統防爆箱. 可依使用者要求自訂不同的外殼材料, 普遍採用鋁合金, 不銹鋼, 以及稀有絕緣材料. These control boxes are mainly employed in explosive hazardous environments and include components like circuit breakers, 接觸器, 熱繼電器, converters, signal lights, 按鈕, ETC。, with component brands selectable according to user preferences.
1. 安裝過程中, inspect the parts and components as well as the dimensions to avoid any omissions.
2. When installing the control box, avoid striking, touching, or scratching the explosion-proof surfaces to ensure they remain smooth.
3. The box should not be struck with screws or nuts, nor should inappropriate screwdrivers and wrenches be used during installation.
4. Prior to assembling the electrical components in the control box, conduct a pressure test as required, maintaining a pressure of 1MP for 10-12 秒.
5. When assembling the electrical parts of the box, ensure the 防爆箱 is installed in the correct location and secured firmly to guarantee stability.
6. Mark the assembled box with a marker, ensuring clear and complete line numbering. Pay attention to the order of colors and wire diameters when wiring to prevent confusion and ensure clarity.
7. 安裝後, perform a trial run as per the electrical design requirements.
8. Tighten the cable bundles and install the trunking covers after the trial run, checking that the ground wire is properly connected.
9. Before tightening the box cover, evenly apply 0.1-0.3mm3# calcium-based grease to the explosion-proof surface of the box to prevent corrosion and water ingress.
10. When fastening the cover, use a tightening torque of 18N,米, applying screws in a symmetrical, progressive, and uniform crosswise manner.
11. 安裝後, tighten the box cover with a plug gauge and check the explosion-proof gap, ensuring the maximum gap is no less than 0.1mm.
12. Once assembly is complete, clean the surface of the explosion-proof box. Appropriately package it with foam to prevent damage to the box’s structure and surface coating during transportation and installation, and to avoid water ingress.
