Detailed Product Description: | PXK51-proof positive pressure cabinet: I. Scope 1. Pressure explosion-proof distribution cabinets for chemical, offshore drilling platforms, metallurgy, medicine, light industry, textile, food, bio-engineering, aerospace engineering, and military and other explosive gas or dust environment, as the three-phase four-wire (380V / 220V) AC low voltage electrical power distribution system or instrumentation, analytical instruments, monitors, micro-computer touch screen, high-power inverter and other components for monitoring and control. 2. For a Zone 2 hazardous locations. 3. For IIA, IIB, IIC class, temperature class T1-T4 explosive atmosphere. 4. Proof positive pressure cabinet indoor and outdoor installation. Second, the principle of using dielectric isolation explosion ignition source explosion-proof measures. Namely: the user used electrical components are mounted on a full clean gas pressure inside the cabinet, so that the external environment flammable gas mixtures can not come into contact with electrical components generated during normal operation of the spark or dangerous temperature, so as to achieve the purpose of electrical explosion. Fourth, the product features 1. Pressure explosion-proof distribution cabinets mainly by the cabinet, automatic control systems, gas distribution system, alarm system, power distribution system components; cabinet and sub-chamber by the pressure chamber composed of cavity pressure distribution system components installed user and vice chamber mounted automatic control system. 2. Products using GGD cabinet cabinet, main dish is about structure, seat-mounted cable channel, the next line, the front door operation, backdoor overhaul. 3. Box-quality products using steel plate welded structure, main and auxiliary drive for the vertical structure, hanging installation, the next line, the front door operation and maintenance. 4. Qin desktop products using high quality steel folding welded, main and auxiliary plate for the front and rear structure, seat-mounted, down the line, the song of operation, the back door overhaul. 5. Press the inlet is divided into ventilated and compensated. Vented gas supply for the continuous operation, positive pressure chamber mounted components work with gas heat can be taken away, with good heat dissipation, high-power explosion-proof inverter suitable for solving thermal problems; compensating for the intermittent supply , have a good seal chamber pressure to ensure low air consumption. 6. Users are required to provide gas source requirements: clean air or nitrogen gas source pressure is: 0.2 ~ 0.8Mpa; usually wind instrument user site can meet the requirements. 7. Steel materials are generally cold-rolled steel with GB710-88, can also be selected according to user requirements GB3280-84 stainless steel. Five features that PxK series explosion pressure cabinet: 1. Product settings ventilation chain, product before operation, and only after the main dish cavity ventilation and the required ventilation time and the amount of ventilation, make sure the main dish in addition to the internal blow flammable gases, Vice disk to the power and began testing the main chamber pressure, to ensure that products put into operation, the electrical components have been clean media effectively isolated. 2. Only the master disk cavity pressure to meet the requirements prescribed pressure, the Deputy tray supply automatic switching system will send power to the main chamber. 3. Working pressure of the master disk cavity 100Pa ≤ P ≤ 1000Pa. When the pressure is higher than 1000Pa, the automatic control system automatically shut down the air intake or exhaust valves open automatically adjust the internal pressure to ensure that products are not deformed by high-pressure shock damage. When the air pressure is lower than 100Pa, the automatic control system automatic alarm and open the inlet to automatically adjust the internal qi, qi is successful, automatically return to normal, unsuccessful and the internal pressure drops 60Pa, if necessary, the system can be set to automatically power down. 4. Vice-disc automatic control system for the continuous operation monitoring, and displays the main dish each cavity pressure parameters. Cabinet pressure Pz series dedicated to the design of a zone 2 pressure-proof cabinets, Pz and Px series compared to the series, are omitted ventilation time checking safety device, only the mark ventilation time by the user in the main chamber before energizing as required; addition, when the internal pressure is less than 100Pa, the automatic control system automatic alarm and open the inlet to automatically adjust the internal qi, qi is successful, automatically return to normal, unsuccessful and when the internal gas down to 60Pa The system does not automatically power off, intermittent alarm. (Huanghua Fang 15637170997) six, the main technical parameters Ex marks Protection Working pressure gas source pressure ExpdeIIBT4 ExpdeIICT4 IP65 60 ~ 1000pa 50 ~ 500pa 0.2 ~ 0.8Mpa |
