I’m really busy today. I haven’t eaten since morning! In order to rush the goods for the customers in Beijing, we are working overtime and trying to get the goods out around 1:00 p.m. A batch of special lighting tiles for granaries ordered by the customers in Beijing have been completed today after more than a week of work. Our explosion-proof If the cable introduced from the lamp to the lamp is likely to be subjected to pulling force during the entire process from installation to use, a cable anti-pull-out pressure plate should be added to the compression nut of the introduction device or inside the lamp close to the introduction device to prevent the force from being transmitted to the terminals and Prevent possible movement of cables and prevent poor contact or failure of electrical connections. The lamp may need to provide more than one introduction device during design to facilitate users' different installation requirements. When leaving the factory, all introduction devices should be installed with sealing parts, and the structure of the sealing parts must be suitable for the explosion-proof type. Alternatively, install only one entry device and replace the remaining holes (after removal of the entry device) with bulkheads suitable for the type of explosion protection. In this way, the failure of the flameproof enclosure will not be caused by forgetting to seal the redundant introduction device. Explosion-proof lamps are inseparable from transparent parts, and transparent parts are the lowest-strength parts of the housing components. Therefore, whether the installation of transparent parts is reliable directly affects the safety performance of explosion-proof lamps. Let's analyze the three commonly used installation methods of transparent parts. The transparent parts are directly sealed in the shell and form an integral whole with the shell. This method is simple, practical and widely used. The sealing material should be heat-resistant and oil-resistant rubber parts, or use epoxy resin and other adhesives to seal the transparent parts in the shell and press them tightly. b) Fasten the transparent piece directly into the shell with or without a liner. When the liner is not used, the flatness of the joint surface of the transparent parts is very demanding. It is generally suitable for small flat glass and the glass joint parts must be ground flat at the same time. Otherwise, the glass will be unevenly stressed and easily broken. ) is sealed or glued to a frame that is fastened within the housing, allowing the clear piece to be replaced as a unit. This structure is rarely used in lamps. In some large equipment that requires frequent replacement of transparent parts, the transparent part and frame are replaced as an integral component. For the sealing of transparent parts and frames, please refer to the type of ). Structurally, the force (generated by internal explosion) on the transparent part should be transmitted directly to the metal shell as much as possible. It is inappropriate to transmit it to the metal shell through the pressure plate and or screws of the transparent part. At the same time, after the transparent part is installed, It cannot be subjected to stress, so as to ensure that the transparent part and the shell are combined reliably.

The selection, installation, use and maintenance of explosion-proof lamps are indispensable links to ensure the long-term safety, reliability and efficient operation of explosion-proof lamps, and must be given full attention . Selectors must understand the basic working principles of explosion-proof lamps and be familiar with explosion-proof signs. According to the level of explosive hazardous locations, accurately select the explosion-proof category, type, level and temperature group of the lamp. Understand the usage environment conditions and work requirements, and rationally choose explosion-proof lamps with various functions. For example: the protection level of the outer shell of explosion-proof lamps for outdoor use must be at least 3. In places where color discrimination is required, explosion-proof lamps with high-pressure mercury lamps and high-pressure sodium lamps cannot be used because these two light sources have poor color rendering. Read the product instruction manual in detail to understand the product's performance, precautions and product limitations, and understand the contents of all product marks. If there is a symbol on the explosion-proof certificate number, it means that the lamp has specific applicable places. You should check the product instruction manual and nameplate to clarify the applicable place requirements. Our factory provides large and small power explosion-proof lamps for use in various places all year round. Customers who need consultation can call us at any time. Our factory has professional instructors to answer your questions.
