Can the air compressor be set in the explosion-proof area?

The air compressor can be set in the explosion-proof area, but must strictly abide by the explosion-proof standards and regulations.

The explosion-proof standard for air compressors is a comprehensive safety standard designed to ensure that air compressors will not cause explosions when operating in flammable and explosive environments. These standards cover the design, manufacture, installation, use and maintenance of air compressors.

Design stage

in the design stage of the air compressor, the explosion-proof requirements must be fully considered. This includes the selection of suitable materials, the design of reasonable structure and the use of effective explosion-proof measures. For example, the shell of an air compressor should be made of a material that is strong and not prone to sparks to prevent an external explosion in the event of an internal failure. At the same time, the air compressor should also be equipped with reliable explosion-proof devices, such as safety valves, explosion-proof plates, etc., to ensure that the pressure is too high or abnormal temperature can be timely pressure relief or power off, so as to avoid the occurrence of explosion accidents.

Manufacturing stage

in the manufacturing process of the air compressor, the manufacturer must strictly abide by the explosion-proof standards. The use of advanced production technology and strict quality control system to ensure that each air compressor meets the explosion-proof requirements. In addition, the manufacturer shall provide the user with detailed explosion-proof instructions and operating instructions so that the user can use the air compressor correctly and safely.

Installation phase

during the installation of the air compressor, explosion-proof standards must be followed. The user should choose the installation site that meets the explosion-proof requirements, and ensure that the installation and wiring of the air compressor meet the relevant regulations. For example, the air compressor installation environment layout requirements, the room and the emission of explosive, corrosive, toxic gases, dust and other harmful substances must have a certain distance, the machine room should be oriented to have good ventilation, and minimize the sun. The compressor room shall be an independent building, and must be equipped with fixed fire extinguishing carbon dioxide fire extinguishing equipment, and its manual switch must be set outside the danger area.

Use and maintenance phase

when using an air compressor, the user should operate in strict accordance with the operating instructions, and regularly inspect and maintain the air compressor to ensure that its explosion-proof performance is always maintained in good condition. Maintenance personnel should receive professional explosion-proof training and be familiar with the explosion-proof structure and principle of the air compressor. During the maintenance process, the operating procedures should be strictly followed to avoid sparks or high temperatures and other factors that may cause an explosion.

SPECIFIC REQUIREMENTS

• cooling system: The temperature rises sharply after the air is compressed, and the air compressor must be equipped with an effective cooling system. The cooling water system of large air compressor shall be equipped with anti-water-break protection device, which must be sensitive and reliable.
• Alarm and Interlock Device the large air compressor shall be provided with alarm interlocking devices for surge, vibration, oil pressure, water supply, shaft displacement and bearing temperature according to the equipment characteristics. Airdrop test shall be done before driving.
• Safety signs and protection: The entrance of the air compressor room shall be provided with a name board and a sign board of "No Entry Without Permission. The pipeline of air compressor room shall be provided with "compressed air and flow direction" mark and "high pressure gas" safety sign. Air compressor filter must be regularly cleaned and replaced wearing parts. It is strictly forbidden to dismantle the safety protection device. If the safety protection device fails, it shall be shut down for maintenance immediately.

Generally speaking, although the air compressor can be set in the explosion-proof area, it must strictly abide by the explosion-proof standards and regulations, and ensure the safe operation of the air compressor from the aspects of design, manufacture, installation, use and maintenance.
