What should be paid attention to during the maintenance of ventilation equipment

Now many of them have set up civil air defense shopping malls in the prosperous areas in order to better promote economic development. In fact, there are some differences between the civil air defense mall and the ordinary mall. Due to the long time underground, the ventilation effect is very limited. Then we need to use air defense ventilation equipment. So, what are the precautions in the use of civil air defense ventilation equipment? 

1. The processing of the centralized civil air defense console, the civil air defense button, the local console of the section partition door, the centralized signal display screen, the ventilation mode signal light box, the door leaf junction box and the door frame junction box shell must be done; the shell welding must be firm and solid, the welding slag shall be removed thoroughly; the anti rust primer shall be sprayed, and there shall be no dead angle inside and outside; The painting drawing requires that the color of the top coat and the baking paint should be bright to ensure the quality of the surface painting and improve the corrosion resistance of the civil air defense equipment.

2. Install sealant strip around the door body of civil air defense equipment for moisture-proof and dust-proof; install moisture-proof lamp in the ventilation mode signal control box to improve the moisture-proof ability of civil air defense equipment.

3. The ventilation equipment shall conduct high and low temperature aging treatment and screening for the purchased qualified components; power aging treatment and screening. Ensure that the components used in the civil air defense equipment are qualified products. Improve the anti environment interference ability of civil air defense equipment

4. Strengthen the protection of civil air defense equipment in the use stage. Due to the large dust in the local control room of civil air defense and each civil air defense control point, the following protective measures should be taken. The plastic dust cover should be used for a long time to protect the dust. The internal and external sanitation of the equipment should be cleaned regularly to keep the equipment clean. The equipment should be electrified and operated regularly to maintain it.

5. Improve the quality of civil air defense equipment.

In the process of installation of civil air defense ventilation equipment, the ventilation equipment manufacturers need to strictly control the installation quality. The sub contractors of civil air defense equipment must be assessed to ensure that the components and parts are purchased from qualified sub contractors. The purchased components and parts must pass the entrance inspection to ensure that they are qualified products.
