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.
When discussing the oil content standard of air compressor, we need to pay attention to its measurement index and practical application requirements. For oil-free air compressors, especially water-lubricated screw air compressors such as those produced by Shanghai Granklin Group, the oil content of compressed air is a nuclear standard.
Whether the screw air compressor is a special equipment depends on the relevant regulations and standards of different countries and regions. In China, according to relevant regulations, special equipment refers to equipment that involves life safety and is more dangerous, including boilers, pressure
When discussing the field of air compressors, the expression "20 cubic meters of air compressors" is often confusing. In fact, it refers to the displacement of this type of air compressor, that is, the gas volume that can be discharged per minute is 20 cubic meters (m & sup3;/min). This parameter is
In the food industry, the quality requirements of compressed air are very strict to ensure the safety and hygienic quality of food. Among them, the dew point temperature is one of the important indicators to measure the quality of compressed air. The following is a detailed explanation of the compressed air dew point requirements for the food industry
Air compressor tank is a pressure vessel. Definition and use: The main function of the air storage tank is to store compressed air so that it can be released into the air system when needed. This storage method is to meet the needs of the time, or in the air compressor can not meet.
The use method and precautions of the air compressor are as follows: Check whether the valves of each part are in the correct position before operation. Check whether the power cord is intact and whether the plug is loose. Check the oil level of the lubricating oil to ensure that it is in normal condition.
2.5m & sup3;/min What is the air compressor? For the gas demand of 2.5m & sup3;/min, it is necessary to select an air compressor with appropriate capacity to meet this demand. The capacity of the air compressor is usually measured in cubic meters per minute (m & sup3;/min) or cubic feet per
Air compressor models are different for different application scenarios, why the purchase of screw air compressor users are often difficult to have a fixed price? Screw air compressor pressure and flow are generally customized according to demand, the user needs of different industries are different, the standard machine model is fixed, but not necessarily able to meet the needs of users. Customized models are better used in project scenarios to serve the different needs of users.
View detailsWith the development and progress of technology, water-lubricated screw air compressors are also selected by more manufacturers, but some users will have concerns. Is water lubrication really oil-free? Will it be more energy-efficient than micro-oil air compressors? Is the after-sales maintenance cost of air compressors high? Question 1: Water
In terms of manufacturers of single screw air compressors, there are many well-known manufacturers in the market, such as Shanghai Granklin Group. These manufacturers have advanced production technology and rich experience, can provide high-quality single screw air compressor. Off
