1. The outlet temperature of air cooler is lower than 95 C and that of water cooler is lower than 90 C.
2. The vibration value of the air compressor head is as follows: the vibration value of the main engine of the air compressor should be less than 7.5 mm/s;
3. The temperature difference between the input and output of cooling water is about 15 degrees. Reaction cooling systems are either too small or too large. The cooling water flow rate is more than 3.7 l/s.
4. The working environment temperature of air compressor is 0-40 C. Excessive high temperature will lead to too high host temperature, too low will lead to difficulties in starting air compressor;
5. 分油后排气含油量约为1-5ppm (ga55-90机仅为2ppm)，一般压缩空气含油量为3ppm;
5. After oil separation, the oil content of exhaust gas is about 1-5 ppm (ga55-90 machine is only 2 ppm), and the oil content of compressed air is generally 3 ppm.
6. According to the computer board, if the pressure difference of the air filter is less than -0.05ba, the filter element must be replaced.
7. Empty filter particles: 98% in 1 micron, 99.5% in 2 micron and 99.9% in 3 micron.
8. Oil filter core particle: 10 micron; oil filter precision can reach 0.1 micron;
9. Generally, the pressure difference of new replacement is about 0.2 bar, and the maximum pressure difference of oil-gas separator should not exceed 0.8 bar, so it should be replaced immediately.
10. The flash point and solidification point of air compressor oil are 200 C and - 20 C respectively.
11. A. The calculation formula of air compressor gas production is as follows:
1 cubic metre of natural gas per 6KW;
1 kW gas production is 0.1633 M3
B, 1)英国马力(HP) = 0.746kw =746W
B, 1) British horsepower (HP) = 0.746 kW = 746 W
公制马力(HP) = 0.735kw =735W。
Metric horsepower (HP) = 0.735 kW = 735 W.
(Usually this unit conversion is used)
12. Oil content: the initial pressure difference is less than 0,2 mpa, and the maximum working temperature is 120 C.
Oil filtration: the maximum working temperature is less than 120 C, and the maximum working pressure is 1.4-2.5 mpa.
Air filtration: the working temperature is less than 120 C, and the maximum working pressure is 1.4-1.5 mpa.
13. Air compressor power conversion table: cubic * 6.6, as follows:
