Whether the oil-free air compressor needs to be equipped with frequency conversion depends mainly on your actual gas usage scene. Not all cases must be equipped with frequency conversion, which can be judged according to your own working conditions:
no need to install frequency conversion
if your production is stable for a long time, the air compressor is almost always running at full load, and there is almost no fluctuation in gas demand, there is no need to match frequency conversion. The conventional operation mode is more cost-effective and can also reduce the initial equipment input cost.
It is suggested to match the frequency conversion
if the daily gas demand fluctuates greatly and the amount of compressed air required at different times varies significantly, it is more recommended to allocate frequency conversion, which mainly has these benefits:
save energy consumption and reduce electricity costs
when the traditional oil-free air compressor has low gas demand, it can only rely on frequent loading and unloading or emptying of excess gas to adjust, which will waste a lot of electric energy. Frequency conversion can adjust the motor speed according to the actual gas consumption, and output as much gas as it uses, thus avoiding ineffective energy waste and saving a lot of electricity charges for long-term use.
Stable gas supply pressure to ensure production
frequency conversion can adjust the output in real time, so that the gas supply pressure has been kept stable, and the pressure will not fluctuate greatly due to changes in gas consumption, which can better ensure the stability of the production process and avoid unstable air pressure affecting product quality.
Reduce equipment loss and extend life
frequency conversion can realize soft start and soft stop of the motor, reduce the impact on the power grid and equipment when starting, and also reduce the wear caused by repeated opening and closing of the valve and frequent stress on the components, which can extend the overall service life of the equipment and reduce the workload of daily maintenance. At the same time, the speed is lower when the frequency conversion is running, and the noise generated by the operation can be reduced.
Advantages of collocation with water-lubricated oil-free air compressor
the water-lubricated oil-free air compressor itself uses water for lubrication, cooling and sealing, the compression process is closer to the ideal compression state, and its energy efficiency is higher than that of other oil-free models. After matching with frequency conversion technology, the energy-saving advantage can be further enlarged under the working condition of gas fluctuation, frequent loading and unloading are not required, additional energy consumption loss is also reduced, and the overall operation cost will be lower.
Air compressor is a kind of equipment widely used in various industries. Its main function is to compress and store air so as to supply other equipment or processes. Different types of air compressor, the pressure range is also different. The following is a common type of air compressor pressure range
The air pressure used in general machining centers usually needs to meet certain standards and ranges to ensure the normal operation and processing efficiency of the machining center. Specifically: pressure range: machining center in the process of air pressure range is generally 0.4~0.
In the field of modern industry, efficient and environmentally friendly compression equipment has been paid more and more attention. The low-pressure oil-free and water-lubricated screw air compressor produced by Shanghai Granklin Group is an outstanding representative of this trend. The air compressor uses advanced water lubrication technology, Che
Air compressor: an important part of mechanical power, non-special equipment Introduction: In the industrial field, compressed air is a widely used power source. The air compressor, as the key equipment for the manufacture of compressed air, plays an important role in many industries. However, off
The replacement cycle of air compressor filters, including air filters (air filters) and other types of filters (such as oil filters, water filters, etc.), depends on many factors, such as the air compressor's use environment, working load, The quality of the filter and the manufacturer's recommendations.
The equipment using compressed air is not necessarily a pressure vessel. We can summarize and explain from the following points: Definition and characteristics: Pressure vessel is a closed device that is specially used to contain gas or liquid and can withstand a certain pressure. They usually
The quality standard of compressed air for food blown film is that the total oil content is below 0.01mg/m3. Compressed air for food film blowing has a standard oil content of 0.01mg/Nm3 and a gas production of 10 Nm3/min. The cumulative oil content in one hour is 6mg and 180g a month.
The size of the compressor required for a small plant depends on a number of factors, including the specific needs of the plant, the scale of production, the process and the budget. Here are some suggestions to help you determine the air compressor size suitable for small factories: Determine the demand: evaluate
Oil-injected air compressors not only drain but also drain oil, which is a heavy maintenance burden. The water-lubricated oil-free screw air compressor only needs to drain, and the drain is clean water, which is much simpler to maintain. If you are using a fuel injection machine now, don't be lazy about drainage.
To estimate the usage of compressed air in the plant, a comprehensive analysis of equipment list, process parameters and system losses shall be carried out. The following is a systematic estimation process based on industry practice: 1. basic data collection, air equipment census, preparation of "Compressed Air Equipment Ledger", record
