Confirm the relevant information before installing the explosion-proof dome camera

With the development of the coal, petroleum and chemical industries, it is a good development opportunity for the explosion-proof monitoring industry. In order to improve the level of explosion-proof monitoring equipment in dangerous places such as coal mines, petroleum and chemical industries in China, and to ensure the safety of dangerous places in coal mines and petrochemical industries, explosion-proof monitoring enterprises should independently innovate and develop new products. Enterprises should adjust product structure, increase investment in innovation, and constantly develop explosion-proof monitoring equipment with high technological content and independent intellectual property rights. Enterprises should introduce advanced foreign technologies and products, improve their ability to innovate through digestion and absorption, and constantly narrow the gap with foreign advanced technologies and products. Only in this way can the leading products of the explosion-proof monitoring industry reach a higher level.

Explosion-proof ball machines can well prevent electrical fire accidents in dangerous environments and ensure the safety of people's lives and property to a large extent. Many companies now comprehensively monitor explosive and flammable equipment and production workshops, and the use of wired distribution control has further enhanced the potential danger brought by various wires. The use of explosion-proof ball machines is a better choice for many enterprises.

Explosion-proof ball machine is suitable for the zone 0, zone 1, zone 2 where the factory has IIA, IIB, IIC group T1 ～ T6 flammable gas, vapor and air mixture, and zone 20, 21 formed by combustible dust and air. Dangerous areas. Such as petroleum, chemical industry, docks, oil depots, ships, drilling platforms, gas stations, mines, ports, aerospace, military industry, medicine, steel, fireworks production, machinery, food processing storage and other places.

Before installing explosion-proof ball machines in petrochemical enterprises, they should confirm:

1. There are three kinds of markings on qualified explosion-proof electrical products and equipment:

1) It is strictly forbidden to open the cover with electricity and the explosion-proof sign;

2) Product nameplate, namely manufacturer name, certification unit, certification number, applicable gas group and temperature class of explosion-proof structure;

3) Grounding identification.

2. Explosion-proof dome camera is a monitoring product used in dangerous environment. The sign on the casing is marked with “No open the cover with power on”. It is forbidden to open the cover with power during installation or maintenance.

3. During the installation, pay attention to the protection of the flameproof surface to prevent damage to the flameproof surface during disassembly and assembly, and affect the flameproof performance.

4. Install the lead-in device and sealing device properly. The introduction device using the filler must wait until the filler is cured to install the rubber seal ring, and at the same time tighten the compression nut so that it cannot be opened without the aid of a special tool, to prevent improper assembly of the filler or the rubber seal ring introduced into the device, causing "Explosion" or IP protection is invalid.

5. Whether the installation of explosion-proof ball machines and explosion-proof boxes are properly grounded according to requirements.

6. When the explosion-proof ball machine is damaged or has defective parts, please do not put it into installation and operation, otherwise an accident may occur.

7. It is strictly forbidden to modify the structure of the explosion-proof ball machine without authorization. Failure to do so may cause a safety accident.
