PXK series explosion proof positive pressure cabinet with left and right cavities
█ features of PXK series explosion-proof positive pressure cabinet with left and right cavities
1. The shell of the product is welded with high-quality steel plate or stainless steel, and the surface is sprayed with electrostatic powder after high-speed polishing, with beautiful appearance;
2. This product is a "Zhongtong explosion-proof" improved explosion-proof product, which can be installed with various common detection instruments, analysis instruments, display instruments, transformers, soft starters, frequency converters, PLC, various buttons, switches, micro-computer touch screen and ordinary electrical components according to the user's requirements, and the installation of electrical components is not limited;
3. Diversified design, including cabinet type (upper and lower form, left and right form), wall hanging type, piano table type, plane type, etc;
4. The power distribution cabinet is composed of cabinet body, control system, air distribution system, alarm system and power distribution system; the explosion-proof components of some control systems and the power distribution system components of users are installed in the positive pressure chamber (split type or online type can be customized according to customer requirements);
5. The air intake mode of the left and right cabinets is ventilation type, i.e. continuous gas supply. The working heat of the components installed in the positive pressure chamber can be taken away with the gas path, which has good heat dissipation effect.
6. This product is designed, manufactured and inspected according to gb3836.1-2000, gb3836.5-2004 and relevant standards.
7. The automatic control system mainly completes high-end functions such as air exchange, air supplement, ultra-high pressure automatic alarm and exhaust, air pressure alarm, low-voltage interlocking power-off and other high-end functions.(the positive pressure cabinet has the function of low-voltage interlocking, when the pressure is lower than the specified value (50pA), the power distribution of users in the positive pressure chamber will be automatically cut off);
8. External protective door can be installed according to customer requirements, which can display the display or action of internal control part;
9. All fasteners are made of 304 stainless steel with strong corrosion resistance;
10. Wiring mode, steel pipe or cable, explosion-proof hose can be used;
11. It can be customized according to user's requirements;
Under the control of the automatic control system, the positive pressure cabinet is filled with protective gas, and the pressure in the positive pressure chamber is higher than that outside the positive pressure chamber, forming a small safe environment with micro positive pressure, thus preventing the combustible dangerous gas from entering the positive pressure chamber and ensuring the safe operation of the internal ordinary instruments and electrical components.
