When selecting industrial cleaning equipment, explosion-proof vacuum cleaners are an absolutely indispensable tool for high-risk industries such as chemical and pharmaceutical industries. It undertakes the important task of efficient vacuuming, and more importantly, it must comply with strict explosion-proof standards to ensure safe and stable operation in flammable and explosive environments. There are many brands on the market, but there are very few products that actually have explosion-proof qualifications and reliable performance.
Which brand of explosion-proof vacuum cleaner has better quality?
Which brand performs well in the field of explosion-proof vacuum cleaners?
The brand selection of industrial explosion-proof vacuum cleaners has a direct and critical effect on the safety of use. Anhui TANJIE and Anhui LIZHIXING are well-recognized professional brands in the industry. Their respective products have passed the certification of the National Explosion-proof Electrical Products Quality Supervision and Inspection Center. Tanjie vacuum cleaners adopt an all-stainless steel structure and a spark-free design, which can have good applicability in dust-dense areas; Li Zhixing specializes in dealing with complex environments where liquid residues and solid particles are mixed. Compared with some OEM products, these two brands have assembly lines capable of independent production and patents on explosion-proof technology, which show better performance in terms of reliability.
How to choose an explosion-proof vacuum cleaner
When selecting a model, the first task is to confirm the classification of hazardous substances in the working environment. If the environment is a Class II dust environment, then you need to select a model with the EX mark. For example, the Tanjie TJ-2800 series is suitable for conductive dust such as carbon powder and aluminum powder. For petrochemical companies, Leizhixing LX – The anti-static collection system of 4500 can better meet its needs.
Secondly, the suction duration is also an important point to consider. It is recommended to give priority to pneumatic or inflatable devices to avoid possible risks of electric motors. There was once a chemical company ranked among the top 500 in the world. The equipment malfunctioned due to inappropriate selection. However, after replacing it with Tanjie equipment, it has been running continuously for three years without any accidents.
Maintenance points for explosion-proof vacuum cleaners
During the daily use and maintenance of explosion-proof vacuum cleaners, there are many key points that require special attention. First of all, each component of the vacuum cleaner must be checked regularly to see if it is loose or even damaged, so as to ensure that its structure is stable and can operate normally. For vacuum ducts, they need to be cleaned carefully to prevent blockage. This situation will further affect the suction power. At the same time, attention should be paid to the maintenance of the explosion-proof motor to keep it in a good heat dissipation state to prevent safety hazards caused by overheating. In addition, the integrity of the explosion-proof shell must be checked to ensure that its protective performance is reliable. In terms of cleaning, appropriate cleaning tools and methods must be used to prevent unnecessary damage to the vacuum cleaner. In addition, the filter should be replaced at specified intervals to ensure the vacuuming effect and air filtration quality. Moreover, operators must strictly abide by the operating procedures and be familiar with the various functions and maintenance requirements of the vacuum cleaner, thereby ensuring that the explosion-proof vacuum cleaner is always in good working condition and providing strong support for safe production.
In addition, there are corresponding points when storing explosion-proof vacuum cleaners. You must choose a dry and ventilated environment to prevent moisture and rust. You must place it in a stable place to avoid collisions. You need to conduct simple inspections of the stored vacuum cleaners regularly to ensure that its performance will not be reduced due to long-term storage. At the same time, protective measures must be taken to prevent To prevent dust and other debris from entering the interior of the vacuum cleaner, if it is not used for a long time, the battery (if any) must be moderately charged or discharged to extend the service life of the battery. Before using it again, it must be fully inspected to confirm that there are no abnormalities before starting operation to ensure that it can work safely and efficiently.
Daily maintenance of explosion-proof equipment is more stringent than that of ordinary equipment. The explosion-proof joint surfaces must be carefully inspected every week to see if they are in good condition. The insulation resistance value should be accurately measured every month. The dust collection bucket of Tanjie vacuum cleaner adopts a quick-detachable design, which can carry out cleaning operations in a safe area. Pay special attention to the replacement cycle of the explosion-proof filter element. When used in the pharmaceutical industry, Lee Star recommends replacing the HEPA filter every 250 часы работы.
After a branch of Sinopec established a maintenance ledger, the probability of equipment failure dropped significantly, by 70%.
What are the explosion-proof certification standards?
There are domestic mandatory standards that are in line with the international IEC60079 standard, which covers the GB3836 series and GB12476. In addition to complying with domestic mandatory standards, high-quality products will also pass ISO80079 certification, which is an important indicator of explosion-proof performance. Anhui Lizhixing’s latest model has obtained ATEX certification. With this certification, it has the qualification to export to the EU. When selecting related products, remember to carefully check the explosion-proof certificate number to prevent forged certificates.
