After the explosion-proof air compressor is selected, does the cabinet need explosion-proof treatment?
After the explosion-proof air compressor is selected, the cabinet still needs to do corresponding explosion-proof treatment, which can be sorted out from the safety logic and actual requirements:
why has the explosion-proof air compressor been selected and the cabinet needs explosion-proof treatment?
The explosion-proof treatment of the explosion-proof air compressor is mainly aimed at the main engine of the air compressor and its own matching power components, while the cabinet is generally used to place the control electrical components of the air compressor, such as switches, frequency converters and controllers. These electrical components may produce sparks or abnormal temperature when working. If explosion-proof treatment is not done, it will still become a potential safety hazard in an environment with explosion risk. Therefore, the explosion-proof of the air compressor itself cannot cover the risk.
If the water-lubricated explosion-proof air compressor is used, it is lubricated and sealed with water, no additional oil circuit system is required, and the overall operation produces fewer additional pollutants. However, the corresponding explosion-proof treatment of the supporting control cabinet is also required to completely cover the safety requirements of the entire system.
Processing requirements in different scenarios
explosion-proof treatment must be done in the environment with explosion risk
as long as it is placed in a place with explosion risks such as combustible gas and dust, the cabinet itself must meet the explosion-proof requirements. It is necessary to make corresponding structural design for the cabinet according to the explosion-proof standards. Through sealing structure or positive pressure protection, the electric spark, high temperature generated by internal electrical components and flammable and explosive substances in the external environment are isolated, and the risk of ignition source is eliminated from the whole system level to meet the safety specifications.
Common security environment can be selected as needed
if the air pressure system is placed in an ordinary place without explosion risk, only the air compressor itself is required to be explosion-proof, and the cabinet does not need additional explosion-proof treatment. The conventional structure can meet the demand and reduce the initial investment cost.
Matters needing attention in matching with water lubricated air compressor
the operating characteristics of the water-lubricated air compressor itself make it unnecessary to frequently maintain the relevant parts of the oil circuit, and the whole system has fewer impurities. When used with the explosion-proof cabinet, it will not add additional maintenance burden to the explosion-proof structure. Only the sealing and explosion-proof state of the cabinet need to be checked regularly, the safe operation of the whole system can be maintained for a long time, while retaining the energy-saving advantages of the water-lubricated air compressor itself.
