Positive Pressure Explosion-proof Cabinet for Mixed Sewage Electromagnetic Flowmeter with Electric Heater Used in GBI Zone, Ergon Explosion-proof Instrument Control Cabinet

Product Features

1. The explosion-proof principle of positive pressure type is to adopt the explosion-proof measure of isolating the ignition source by medium to achieve the purpose of electrical explosion-proof.

2. This product can be installed with various common detection instruments, analytical instruments, display instruments, monitors, microcomputer touch screens, high-power frequency converters, and ordinary electrical components according to user requirements, with basically no restrictions on the internal electrical components.

3. The product mainly consists of a cabinet body, an automatic control system, an air distribution system, an alarm system, and a power distribution system; the cabinet body is composed of a positive pressure chamber and an auxiliary chamber. The positive pressure chamber houses the user's power distribution system components, and the auxiliary chamber houses the automatic control system.

2. The cabinet-type product adopts a GGD cabinet frame, with the main and auxiliary panels arranged left and right, seat-type installation on cable trenches, bottom inlet, front door operation, and rear door maintenance.

3. According to the air intake mode, it is divided into ventilation type and compensation type. The ventilation type provides continuous air supply, and the heat generated by the components in the positive pressure chamber can be carried away by the air path, providing good heat dissipation, suitable for solving the heat dissipation problem of high-power explosion-proof frequency converters; the compensation type provides intermittent air supply, and the positive pressure chamber must have good sealing to ensure low air consumption.

6. The user must provide a gas source, which should be purified air or nitrogen, with a gas source pressure of 0.2 to 0.8 Mpa; usually, the instrument air at the user's site can meet the requirements.

7. The steel plate material is generally GB710-88 cold-rolled steel plate, and GB3280-84 stainless steel material can also be selected according to user requirements.

Product Advantages:

1. The new explosion-proof positive pressure cabinet uses American Dwyer differential pressure switches and instruments, imported AirTac pneumatic components, pure mechanical control, safer, more practical, and more reliable. The automatic control system has a liquid crystal display, high integration, small size, stable operation, and good visibility.

2. The positive pressure explosion-proof distribution cabinet is of the positive pressure ventilation type. When the pressure inside the cabinet exceeds 500 PA, the mechanical automatic pressure relief valve automatically relieves pressure, and the heat inside the cabinet is discharged with the gas, providing good ventilation and heat dissipation. When the pressure drops below 100 PA, the audible and visual alarm sounds; when it drops below 50 PA, the power is automatically cut off.

3. An oil-water separator is used to separate oil and water, keeping the air entering the cabinet clean.

4. Our cabinets all use flow equalizing pipes, and the material is red copper cloth pipe, which not only filters out many impurities but also maintains balanced pressure inside the cabinet, truly achieving the positive pressure explosion-proof effect.

5. Our panel uses anti-static touch panels, and internal and external grounding are safer and more reliable.

6. Our positive pressure cabinet uses a small door outside the touch screen to prevent dust and accidental operation.

7. Even the screws of the seals on our cabinets are made of 304 stainless steel, which is not easy to rust.
