During the operation of air compressor, all kinds of data show the "health status" of the equipment. Experienced technicians can find problems and energy-saving space from the real data.
Mastering some basic general data in the operation of air compressor is very helpful for us to maintain the equipment, summarize the rules and better use the air compressor. Let's get to know!
1. Host operation data
The outlet temperature of the machine head is below 95 ℃ for the air cooler and below 90 ℃ for the water cooler. If the temperature exceeds 110 ℃, the machine will jump at high temperature;
The ambient temperature of air compressor is 0-40 ℃. Too high will lead to the phenomenon of high temperature of the main engine, too low will lead to the difficulty of starting the air compressor;
The head vibration value of the air compressor is: the vibration value of the main engine of the air compressor should be less than 7.5mm/s
2. Operation data of three filters of air compressor
After oil separation, the oil content of exhaust gas is about 1-5ppm, and that of compressed air is 3ppm;
The control panel shows that if the pressure difference of the air filter is lower than - 0.05ba, the filter element must be replaced;
Air filter particles: 98% for 1 micron; 2 μ m is 99.5%; 99.9% for 3 micron
Filter particles of oil filter: 10 μ m ； The filtration precision of oil can reach 0.1 μ M;
Generally, the partial pressure difference of new oil is about 0.2bar; The maximum pressure difference of oil-gas separator shall not exceed 0.8bar, and it shall be replaced immediately if it exceeds;
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: the working temperature is less than 120 ℃, the maximum working pressure is 1.4-1.5mpa.
3 other common data
The temperature difference between cooling water input and output is about 15 degrees. If it is too large or too small, there is something wrong with the cooling system. And the cooling water flow is more than 3.7 L / s;
A. The calculation formula of air compressor gas production is: 1 cubic meter of gas per 6kW; The gas production of 1 kW is 0.1633 m3
B. (1) British horsepower (HP) (HP) = 0.746kw = 746w;
(2) Metric horsepower (HP) (HP) = 0.735kw = 735w (this unit is usually used for conversion);
Air compressor power conversion table: cubic * 6.6;
Air compressor oil: flash point temperature is 200 ℃, freezing point is - 20 ℃.
