Purchase air compressor need to know the data, different air compressor data is not the same, need to match the appropriate air compressor according to the specific use of the scene, after understanding the basic data of the series of air compressor to better purchase.
1. The outlet temperature of the head is below 85 ℃ for the air cooler and below 80 ℃ for the water cooler. If it exceeds 110 ℃, the phenomenon of high temperature jump will occur;
2. The vibration value of the air compressor head is: the vibration value of the air compressor host should be less than 7.5 mm/s;
the temperature difference between the cooling water input and output is about 15 degrees. Too large or too small both reflect problems with the cooling system. And the cooling water flow rate is more than 3.7 liters/second;
4. The ambient temperature of air compressor is 0-40 ℃. The phenomenon that the temperature of the host is too high, and the air compressor is too low to start;
5. After the oil is separated, the oil content of the exhaust gas is about 1-5ppm (only 2ppm for the GA55-90 machine), and the oil content in the general compressed air is 3ppm; Granklin Air Compressor
6. The computer board shows that the filter element must be replaced if the pressure difference value of the air filter is lower than-0.05ba;
7. Air filter particles: 98% for 1 micron; 99.5 for 2 microns; 99.9 for 3 microns;
8. Filter particles of oil filter: 10μm; The filtration accuracy of oil can reach 0.1 microns;
9. Generally, the differential pressure value of the newly replaced oil is about 0.2bar. The maximum differential pressure value of the oil-gas separator cannot exceed 0.8bar, and it should be replaced immediately if it exceeds the maximum;
10. The flash point temperature of air compressor oil is 200 ℃, and the condensation point is -20 ℃;
11, A, air compressor gas production calculation formula is:
1 cubic meter of gas per 6KW;
1 kW gas production is 0.1633 m3
b, 1) inch horsepower (HP)(horse) = 0.746KW = 746W
2) Metric horsepower (HP)(horse) = 0.735KW = 735W.
Granklin water lubricated air compressor (usually converted by this unit)
12. Oil content: the initial pressure difference is ≤ 0,2mpa and the maximum working temperature is 120 ℃;
oil filter: the maximum working temperature is less than 120 ℃, and the maximum working pressure is 1.4-2.5mpa;
air filter: working temperature is less than 120 ℃, maximum working pressure: 1.4-1.5mpa
Q: What is the compressed air regulatory standard for the food industry? A: ISO International Standard: ISO 8573-1:2010. Reference content: Compressed air introduced by [National Standard Project-National Standard Information Public Service Platform] Part 1: Pollution
Air compressor with oil and without oil has its advantages and disadvantages, which is better depends on the specific use of the scene and needs. The oil compressor needs to use lubricating oil during operation, which may cause the discharged compressed air to contain oil molecules. These oil molecules can
In LNG (liquefied natural gas) production, the control standard of oil content of feed gas is extremely strict. According to industry specifications and actual production requirements, the oil content in LNG feed gas usually needs to be controlled below 1 mg/m & sup3; (I. e. not more than 1ppm). The following is a detailed analysis: 1. contains
Air compressors and cold dryers play an important role in industrial production. The relationship between them is mainly reflected in the following aspects: 1. definition and function Air compressor: Definition: Air compressor is a machine that compresses air to a certain pressure. It is inhaled from
The requirements of chemical process for compressors include the following aspects: the requirements of process parameters such as gas volume, pressure and temperature should be met. Should meet the requirements of the media characteristics. For flammable, explosive and toxic gases, the shaft seal is required to be reliable; for corrosion
Explosion-proof air compressor due to the manufacture of strict control, high technical requirements, so its application field is narrow, then explosion-proof air compressor in which areas have applications?
There is no absolute answer to the question of whether the air compressor is oil-free or oil-free, because it depends on the specific application requirements and scenarios. The following is a comparative analysis of oil-free air compressors and oil-free air compressors to help you make a more comprehensive decision. Oil-free air compressor
The dryness of compressed air source is a key indicator to measure the water vapor content in the air, which directly affects the safety of equipment operation, product quality and process stability. The following from the technical principles, influencing factors and control strategies of the three aspects of professional elaboration: 1. dryness of the nuclear.
Through the use of cold dryer to improve air quality, the core is to efficiently remove water vapor, oil and particulate matter in compressed air, so as to prevent equipment corrosion, pneumatic component failure, product pollution and other problems. The following is the specific principle of cold dryer to improve air quality, operation
The role of compressed air in the operating room: In the operating room, compressed air plays a vital role. It is mainly used to drive various medical equipment and tools, such as scalpels, drills, saws, staples, etc. It also provides clean and dry space for the operating room.
