Air compressor users are often troubled by deposits such as sludge carbon deposits. These harmful substances affect the operating efficiency of the air compressor, increase maintenance costs, and cause serious accidents such as shutdown and explosion.
reasons for the formation
high temperature: high temperature is the decisive factor that causes the oxidation and deterioration of lubricating oil. The higher the temperature, the faster the oxidation rate, and the greater the possibility of forming carbon deposits;
pressure: After the air is compressed by the air compressor, the pressure increases and the oxygen concentration increases, which increases the oxidation rate of the oil and the possibility of the formation of carbon deposits;
metal catalysis: metal plays a positive catalytic role in the oxidation reaction and accelerates the reaction;
the type of air compressor oil: the quality and addition of air compressor oil will have different degrees of influence on the formation of carbon deposits. If mineral type air compressor oil is used, the unsaturated components in the base oil are more likely to form carbon deposition tendency.
Air compressor explosion accidents are mostly caused by the accumulation of carbon deposits. Carbon deposition is a high-temperature product, but it also spontaneously ignites at high temperatures. Usually, the self-ignition temperature of carbon deposits is about 180 ℃, and the outlet temperature of air compressor is generally not higher than 160 ℃. Under normal operation, carbon deposits will not be ignited. However, when the air compressor due to some fault instantaneous high temperature or high pressure, the air compressor temperature rises sharply, causing spontaneous combustion of carbon deposits, making the oil in the carbon deposits quickly vaporized. When the vaporized oil and gas and the high concentration of oxygen in the compressed air and high temperature exist at the same time, it will cause the compressor to explode and cause an accident.
Control of sludge carbon deposition in air compressor
1. Choose clean high-quality air compressor oil, and replace the air compressor oil regularly according to the maintenance requirements.
2, the selection of high-quality maintenance parts and materials, according to the maintenance requirements of regular replacement. The use of high-quality oil, oil filter, air filter, can effectively filter external and endogenous pollution sources, to ensure the normal operation of the air compressor.
3. Maintain normal working temperature and working pressure to ensure effective ventilation of air compression station.
4. Take auxiliary cleaning method to keep the compressor clean, choose mature online cleaning fluid, clean the air compressor regularly, and keep the head rotor and oil circuit clean.
During the manufacture and installation of air compressors and air storage tanks, as special equipment, daily management must be carried out in accordance with the relevant national and departmental safety management inspection regulations. In recent years, the air compressor explosion caused by the frequent occurrence of safety accidents, to the safety management
What kind of water-lubricated oil-free air compressor is better? Choose the water-lubricated oil-free screw air compressor produced by Shanghai Granklin Group. Granklin GW series air compressor using water standard of pure water lubrication, the entire compression process without the participation of oil. Therefore, the air compressor provides clean compressed air without oil.
View detailsThe air supply pressure used in the machining workshop is usually in the range of 0.5~0.8 MPa(5~8 bar), but the specific pressure value should be determined according to the equipment type, process requirements and safety specifications. The following is a detailed analysis: 1. common equipment air supply pressure demand pneumatic
In the complete air supply scheme of the pharmaceutical factory, the water lubricated air compressor is generally used with drying equipment and filtering equipment to ensure that the air sent to each air point is clean and stable.
The range of compressed air pressure varies depending on the application requirements, depending on the type of compressor, design specifications, operating conditions and the desired application scenario. The following is a general description of compressed air pressure: 1. conventional range In conventional applications, compressed air
Analysis of the relationship between air compressor exhaust pressure and energy saving 1. The definition of exhaust pressure and energy consumption Exhaust pressure refers to the compressed air pressure (such as 0.6-0.8MPa) output by the air compressor, and its setting value directly affects the energy consumption of the equipment. Theoretically, the higher the compressed air pressure, the need to overcome
As a widely used mechanical equipment, the general field of air compressor covers many important industries and scenarios. The following is a rigorous summary of the general field of air compressors: 1. industrial production and manufacturing production line power source: in all kinds of industrial production lines, air compressors are
1. According to its principle, it can be divided into volume type compressor and speed type compressor. Volume type is divided into: reciprocating compressor, rotary compressor; speed type compressor is divided into: axial compressor, centrifugal compressor and mixed flow compressor. Household today.
The warranty period of the air reservoir of the piston air compressor varies according to the manufacturer and product model. Generally speaking, the air storage tank is an important part of the air compressor system, and its warranty period is usually provided when the product is purchased, and it is clearly written in the purchase contract or product manual.
The calculation of compressed air consumption of equipment is a comprehensive problem, which needs to be considered in combination with equipment type, work demand, gas parameters and environmental factors. The following is a detailed calculation method and related factor analysis: 1. compressed air gas consumption definition refers to the equipment in a single.
