The selection of screw air compressor and scroll air compressor should be combined with specific usage scenarios. The following three dimensions of technical characteristics, usage cost and industry adaptability are compared in detail:
| Indicators | screw air compressor | scroll air compressor |
|---|---|---|
| compression principle | male and female rotor meshing compression (volumetric) | scroll rotational compression (volumetric) |
| pressure range | 0.7-3.0MPa (conventional type) | 0.5-2.5MPa (oil-free) |
| gas volume regulation | frequency conversion control (20%-100 stepless adjustment) | unloading valve control (step regulation) |
| energy efficiency ratio | under ISO standard working conditions & eta;& asymp;85-92% | under ISO standard working conditions & eta;& asymp;78-85% |
| vibration value | ≤ 0.5 mm/s (with damping pad) | ≤ 0.3 mm/s (symmetrical design) |
| noise level | 75-85dB(A)(ordinary soundproof cover) | 65-72dB(A)(built-in silencer) |
| Application Scenarios | preferred scheme | technical basis |
|---|---|---|
| pharmaceutical/Electronic Clean Room | scroll machine (oil-free design) | oil content of compressed air <0.01ppm |
| mine/Drilling Site | screw machine (with dust pretreatment) | adapt to high dust environment, heavy load continuous operation |
| food and Beverage Filling Line | scroll machine (IP65 protection class) | waterproof steam design, according to HACCP certification |
| new energy vehicle manufacturing | screw machine (frequency conversion + waste heat recovery) | energy saving 30%, adapt to pressure fluctuation demand |
| laboratory precision instrument | scroll machine (± 0.1bar pressure stability) | no pulsating airflow, to ensure the accuracy of the instrument |
typical case: A photovoltaic manufacturing enterprise found that under the 80% load rate, the annual energy saving cost of the scroll machine can cover the equipment price difference, and the product defect rate decreased from 1.2 to 0.6. It is recommended to make accurate selection through the measured working condition data and the Energy Efficiency Comparison Curve provided by the manufacturer.
Regarding the issue of whether the air compressor condensate needs to be tested for environmental protection, according to relevant national environmental protection regulations and industry standards, the following formal instructions are hereby made: 1. environmental protection regulations require that the the People's Republic of China Water Pollution Prevention and Control Law and the Water Pollutant Discharge Standard
There is no fixed standard for the amount of moisture in the air, as it varies with temperature, humidity, geographic location and other environmental factors. However, we can understand the moisture content in the air according to some common indicators and ranges.
Screw air compressor gap size and vibration relationship: The gap size of the screw air compressor has a direct impact on its vibration during operation. The two screws in the screw air compressor (usually a male screw and a female screw) need to be maintained during the compression process
In the medical compressed air system, the choice of air compressor is very important, which is directly related to the stable operation of medical equipment and the life safety of patients. As one of the leading air compressor manufacturers in China, Shanghai Granklin Group's water-lubricated screw air compressor products are in the medical market.
The pressure of the air compressor is usually determined according to the specific application requirements and will be affected by the use environment and equipment specifications. Generally speaking, the pressure of air compressor can be divided into the following ranges: low pressure air compressor: working pressure is usually between 0.7 and 1.2 M
Regarding the replacement cycle of industrial air compressors, this time interval is not fixed, but is affected by many factors. First of all, the use of the compressor environment has a direct impact on its life. In the harsh working environment, such as high temperature, high humidity or dust
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 industrial production, as an important power source, the selection and configuration of air compressor is directly related to the production efficiency and cost. For a gas consumption of 4m & sup3;/min, it is important to choose a suitable compressor. Water-lubricated snail produced by Shanghai Granklin Group
Compressed air is widely used in pharmaceutical factories. It plays a vital role and is a key factor to ensure drug quality and production efficiency. The following are the main uses of compressed air in pharmaceutical factories: 1. drug production equipment power source filling in liquid preparations
Requirements for solid particle content of compressed air vary according to application fields and specific scenes. International standard ISO 8573-1 and domestic standard GB/T 13277.4 both provide detailed classification and measurement methods. The following are specific instructions: 1. international standard: ISO 8573-1ISO
