Explosion-proof technology

Recently, WeChat and qq have many customers who have asked me some explosion-proof technical problems. It is good to ask more questions, and those questions on Wechat have already been answered. I have collected some questions and sent them to the website. No matter if they are useful or not, for your reference. Prepared
1. Q: Can the metal contact surface between the explosion-proof distribution box door and the box be buttered?
1. A: The metal contact surface between the explosion-proof distribution box door and the box can be coated with butter. The purpose of buttering is not to seal, but to prevent rust. Because the contact surface between the box and the door of the explosion-proof box is processed through the lathe, in order to do anti-corrosion treatment for the box, the box and the box door need to be installed later, so that the contact surface cannot be treated with anti-corrosion treatment. Need to deal with it.
2. Q: Does the explosion-proof power distribution box need to be temporarily used in the chemical plant?
2. A: Of course this is needed. It depends on whether or not this chemical plant is in operation. If it is operated, explosion-proof products are needed for temporary use of electricity. If it is actually constructed, explosion-proof electricity is not required. When the plant is in operation, there is a danger that the dangerous gas will explode when it encounters a spark.
3, Q: The distribution box pushes off the tower crane operating room leakage switch?
3, A: It should be a change of knife caused by electrophoresis.
4. Q: Can I use snake skin hose for explosion-proof distribution box connecting wires?
4, A: Use explosion-proof flexible tube
5. Q: What is the difference between explosion-proof lighting distribution boxes and explosion-proof distribution boxes and explosion-proof power maintenance boxes?
5, A: The shell can be designed as IIB or IIC, the main internal components, circuits, circuit diagrams are different, to achieve different functions, functional tests are based on the internal circuit. Nanyang Zhongtong Explosion-proof Electrical Appliance Co., Ltd. will answer your questions. If you have any questions, you can ask questions!
6, Q: Winery wine shop need to press explosion-proof distribution box?
6. A: The need for wineries and pharmaceutical companies to use a large number of volatile organic substances, the vapor of these substances mixed with air to a certain percentage.
When an explosive concentration is reached, burning or explosion occurs when exposed to open flames, high temperatures, arcs, etc. These workshops naturally become flammable and explosive danger areas. In the electrical design of the workshop, explosion-proof safety must be taken as the top priority.
The use of explosion-proof distribution boxes can effectively prevent such dangerous situations from occurring.
7, Q: How to connect the explosion-proof distribution box into the outlet pipe?
7, A: Commonly used methods
1, the use of explosion-proof Granite brass nickel-plated explosion-proof joints are more upscale.
2, the use of explosion-proof box (cast aluminum) is cheap, practical, easy to buy.
It will be even better if you use an electrician cement.
