A nameplate, also known as a label, generally refers to a label that is fixed on a product after it is put on the market to provide users with information such as manufacturer's trademark identification, brand differentiation, and product parameter memorization.
The nameplate is mainly used to record some technical data of the manufacturer and rated working conditions for correct use without damaging the equipment.
The materials used to make nameplates are divided into metal and non-metal types: metal types include zinc alloy, copper, iron, aluminum, stainless steel, etc., but aluminum is mainly used for production because the processed nameplates have a relatively high-end effect, are durable, and do not rust. Non metallic materials include plastic, acrylic organic boardPVC、PCPaper, etc.
For explosion-proof electrical products and equipment used in explosive hazardous areas, in addition to general product information, their nameplates also need to include explosion-proof technology requirements.
Specifically, what content does the nameplate of explosion-proof electrical equipment include?
1. The nameplate of explosion-proof products must be complete and clear, without missing strokes. The edge of the nameplate is flat without any raised edges;
2. The nameplate must include product name, model, electrical parameters, explosion-proof parameters (intrinsic safety parameters), explosion-proof mark, explosion-proof certificate number, date of manufacture, factory certificate number, and manufacturer information;
3. There should be necessary warning information on the nameplate, such as“It is strictly prohibited to open the lid with electricity on”、“Charging and discharging are not allowed in explosion-proof areas”Wait.
The following are common styles of explosion-proof nameplates:
It is necessary for the nameplate of explosion-proof products to have the following information
1. Explosion proof mark. It can enable users and installers to quickly understand the explosion-proof type and corresponding gas of this explosion-proof product/Dust and temperature group. So as to avoid the installation of gas explosion-proof products in dusty areas,“n”Type product installation to1Explosion proof areas in the district, etc. Ensure that explosion-proof products are compatible with hazardous areas in terms of selection.
2Explosion proof certificatenumber. Can reflect whether the explosion-proof certificate of the product is genuine and valid, and avoid selecting counterfeit or even non explosion-proof products.
3. Date of manufacture. Can quickly determine the product's expiration date, from explosion-proof toZhongnuo TestingDetermine whether to replace a new batch of products based on their lifecycle. To avoid the failure of explosion-proof performance due to long-term use. If the screws of the explosion-proof shell are corroded or missing, the explosion-proof surface is severely corroded, and the sealing ring is aging and cannot achieve the sealing effect.
4. Warning message. It can help maintenance and usage personnel avoid the risk of damage to explosion-proof equipment and even explosions in the surrounding environment caused by improper operation.
In summary, the explosion-proof product nameplate is a very important label. Incomplete or incorrect information can cause unnecessary inconvenience to the usage site and personnel.
