Ex-proof Pressurized Cabin

Explosion-proof Pressurized Cabin Solutions

I. Overview of Explosion-proof Pressurized Cabin
The explosion-proof Pressurized cabin is a safety protection facility used in special hazardous environments. By maintaining a pressure inside the cabin higher than the external environment, it prevents flammable gases, dust, etc. from entering, thereby achieving the purpose of explosion prevention.

 

II. Clarify the usage scenarios and hazard levels
1. Determine the specific industry and working environment where the explosion-proof Pressurized cabin will be used, such as petrochemical, offshore oil drilling, mining, or aerospace, etc.
2. Evaluate the types of potentially explosive hazardous substances (such as flammable gases, volatile liquids, flammable dust, etc.) and their concentration levels in the workplace.
3. Understand the range of changes in temperature, humidity, pressure, etc. in the environment, as these factors will affect the performance and applicability of the explosion-proof Pressurized cabin.

III. Consider the accommodation requirements for personnel and equipment
1. Clearly define the number of personnel in the cabin, their activity range, and the possible equipment they carry, and plan the spatial layout inside the cabin.
2. List the equipment that needs to be placed in the cabin, including parameters such as its size, weight, and power, to ensure there is sufficient space and carrying capacity inside the cabin.
3. Evaluate the installation method and location of the cabin to see if it is convenient for personnel to enter, exit, and operate.

 

IV. Design key points
1. Cabin structure
    - The cabin structure should have sufficient strength and rigidity to withstand external impacts and internal pressure changes. High-strength and impact-resistant metal materials should be used to ensure a stable structure.
    - Reasonably design the cabin door and observation window to ensure good sealing performance while meeting the observation and operation needs of personnel.


2. Pressurized maintenance system
    - Equip with high-precision pressure sensors to monitor the pressure inside the cabin in real-time.
    - Select a reliable gas source, such as compressed air or nitrogen, and set up a stable gas supply system.
    - Install an intelligent pressure adjustment device to keep the pressure inside the cabin within the safe range.
3. Ventilation and purification system
    - Install efficient ventilation equipment to promote air circulation and ensure the air quality inside the cabin.
    - Configure high-quality filter devices to effectively remove harmful gases and impurities.
4. Electrical system
    - Select electrical equipment that complies with explosion-proof standards, such as lighting fixtures, sockets, etc.
    - Reasonably wire to ensure the safety and reliability of the electrical system.
5. Operation and control convenience
    - Determine whether the layout of the operation control panel inside the cabin is reasonable and easy for operators to use and monitor.
    - Consider whether a remote control function is needed for convenient operation in emergency situations.

 

V. Installation and commissioning
1. Installation
    - Professional teams should operate in accordance with strict installation processes and standards.
    - Ensure that the connection between the cabin and surrounding facilities is firm and sealed.
2. Commissioning
    - Conduct pressure tests to check the sealing and Pressurized maintenance capabilities of the cabin.
    - Commission the ventilation and purification systems to ensure their normal operation.
    - Conduct a comprehensive inspection of the electrical system to ensure the safety of electricity use.

 

VI. Maintenance and management
1. Regularly check the sealing of the cabin and repair any leaks in a timely manner.
2. Regularly maintain the Pressurized maintenance system, calibrate the pressure sensor, and check the gas source supply.
3. Clean and replace the filter devices of the ventilation and purification systems.
4. Regularly inspect the electrical system and replace aged or damaged components in a timely manner.
