Stainless steel explosion-proof junction box is a lot of people may not be clear, but you should have seen the dust explosion zha, dangerous gas explosion zha, flammable liquid explosion zha and other accidents reported in the news report, if these are because If the explosion-proof junction box of stainless steel is exploded, the use of stainless steel explosion-proof junction box can avoid the occurrence of explosion zha. The stainless steel explosion-proof junction box is used in those dangerous places to avoid the explosion of zha junction box products.
Three points of attention for the assembly of stainless steel explosion-proof junction boxes:
1. The aluminum alloy distribution box, the components used must be installed in the explosion-proof chamber, and the safety leakage is prevented by the explosion-proof cavity to block the electrical leakage and contact with the dangerous medium on site. Attention should be paid during production: firstly, the guide rail should be placed in the explosion-proof chamber to pay attention to the correct direction. The circuit breaker should be stuck on the guide rail, and then add the mechanism to align the hole at the cover. Install small details at the explosion-proof shaft: There is a small black snap ring on the shaft. It needs to be stuck, fixed and tightened. The position is fixed, the handle operation will be flexible, and the position of the split and break will be clear and clear. Once the handle is stuck, the handle position needs to be re-adjusted.
2, the explosion-proof cavity cover is divided into a high cover and a low cover, generally used is a low cover, if the use of high cover: A, AC 40A or more must use a high cover, such as next to the circuit breaker, but also with the corresponding axis. B, EZD / 4P circuit breaker must use a high cover. C. The customer has additional components provided, and the corresponding high and low covers are provided according to the actual situation.
3. The encapsulation of the explosion-proof cavity. The wire connected in the explosion chamber should pass through the transition nut. The gasket at the transition nut is critical. The gasket is opened according to the diameter and number of the wire. Pay special attention to the diameter of the wire and the diameter of the hole. Match, there is no gap, then press the gasket in the transition nut, it must be flattened. When pouring, pay special attention to whether the sealing gasket leaks. Check the pouring edge to avoid damage to the components. The sealing should be uniform. There are bubbles.
Stainless steel explosion-proof junction box features:
1. Stainless steel or steel plate, the surface is sprayed.
2. Die-casting or welding forming, beautiful appearance.
3. The joint surface adopts a curved road sealing structure, which has strong waterproof and dustproof performance.
4. The terminal block adopts the special-purpose terminal for increasing safety, the wiring is convenient, firm and reliable, and the current size has various specifications for the user to choose.
5. The direction of the inlet port is varied. The inlet port can be arbitrarily selected according to the user's requirements and can be directly equipped with the BMJ series cable gland according to the user's requirements. (Note: The user must specify when ordering.)
6. Meet the requirements of GB3836-2000 and IEC60079 standards.
The price of stainless steel explosion-proof junction boxes is not only determined by your specific needs, but also depends on the specific materials you need. Different hazardous environments have different material requirements. At present, many manufacturers' stainless steel explosion-proof junction boxes are for work, cut corners, and do not have stainless steel explosion-proof junction box production licenses and explosion-proof certificates. The equipment they produce is just like an explosion-proof product. Their products are cheap, and if you buy explosion-proof equipment from such manufacturers, the probability of problems will be very large. Yueqing Changrui Explosion-Proof Electric Co., Ltd. is a science and technology enterprise integrating manufacturing, research and development and sales of electrical appliances. Its product range is complete, standard specifications of explosion-proof electrical appliances and professional lighting, light source, suitable for petroleum, chemical, natural gas, pharmaceutical, electric power, coal, metallurgy, scientific research and military industries. Companies adhering to the "professional explosion-proof, safe and reliable" purpose, the introduction of a large number of professional and technical personnel, production of high-quality explosion-proof electrical appliances; can produce more than 100 series, nearly 1000 specifications of electrical products.
Anodizing Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Anodizing uses chemical or electrochemical treatment to generate a film layer containing the metal component on the metal surface. The metal material as the anode is protected by a material that forms a film on the surface by applying an electric current in a specific electrolyte. Anodizing is a method of metal surface treatment. Most metal materials (such as stainless steel, zinc alloy, aluminum alloy, magnesium alloy, copper alloy, titanium alloy) can be anodized in a suitable electrolyte.
Anodizing is to use aluminum alloy's easy oxidation characteristics to control the formation of oxide layer by electrochemical method to prevent further oxidation of aluminum material and increase the mechanical properties of the surface.
