PX series positive pressure cabinet

PX series positive pressure cabinet

The product is set to change the gas chain. Before the product is put into operation, only after the air is ventilated in the main disk, and after the specified time and the amount of ventilation, it is confirmed.

The main disk is blown away from the flammable and explosive gas, the secondary disk can be powered, and the main cavity pressure is detected to ensure that the product is put into operation.

The components have been effectively isolated by the clean medium;

Only when the air pressure in the main disk meets the specified air pressure requirement, the power supply automatic switching system in the secondary disk will send power to the main cavity;

The working pressure of the inner cavity of the main disk is 100Pa≤P≤800Pa; when the air pressure is higher than 800Pa, the automatic control system automatically turns off the intake or

Open the exhaust valve and automatically adjust the internal air pressure to ensure that the product is not damaged by high air pressure. When the air pressure is lower than 100Pa

The automatic control system automatically alarms (sound and light), and turns on the air intake to automatically adjust the internal air supply. When the air supply is successful, it automatically returns to normal.

If it is unsuccessful and the internal air pressure drops to 60Pa, the system can be automatically powered off if necessary;

The secondary disk automatic control system continuously monitors continuously and displays the pressure parameters of the main disk cavity;

The positive pressure ventilation type is continuous uninterrupted air supply, and the working heat of the electrical components in the positive pressure chamber can be taken away at any time, with good heat dissipation.

Features. Internally, it can be equipped with measuring instruments, analytical instruments, display instruments, low-voltage electrical appliances, soft starters, computers, etc.

Products can be used as equipment start-up, control, central signal processing and control systems;

The positive pressure compensation type is intermittent gas supply, and the positive pressure chamber has good pressure sealing performance;

Multiple models of the same model can be operated in parallel;

When the user supplies the air source, it must be equipped with a clean or inert gas source. Under normal circumstances, the instrument air source at the user site can meet the requirements.

The gas source pressure is 0.2~0.8MPa or 0.2~0.5MPa (determined according to the volume of the main cavity);

The applicable power supply system is AC three-phase four-wire 380/220 system and all weak current systems, not suitable for high voltage systems.

Pz series positive pressure cabinet

For a positive pressure explosion-proof cabinet designed for the 2nd district, the Pz series and the Px series omits the inspection of the ventilation time.

Full device, only indicates the time of ventilation, by the user before the main cavity is energized as required; in addition, when the internal air pressure is lower than 100Pa

When the automatic control system automatically alarms (sound and light), when the air supply is successful, it automatically returns to normal, unsuccessful and the internal air pressure drops to 60Pa.

The system does not automatically power off and continues to alarm.
