Screw type air compressor lubricating oil process and related components function

( supply: Fuyang air compressor water heater, Fuyang air compressor waste heat recovery )

And the mechanical and electrical equipment company limited technical personnel for screw type air compressor system made specific analysis, here to introduce screw air compressor system in the process of lubricating oil flow and related parts and components of the function.

One, the lubricating oil flow:

Oil and gas in the barrel pressure oil gas lubricating oil pressure in the barrel, the oil cooler, oil filter to remove impurities particles, and then divided into two paths, one path from the body bottom is injected into the compression chamber, cooling the compressed gas; another path to the both ends of the body, bearing group, then the various parts of the lubrication oil gathered in the compression chamber at the bottom, from the air outlet. Mixed with oil and compressed air is discharged into the oil and gas barrel, most of the oil deposit in oil and gas barrel bottom, the rest of the oil mist air through the oil separators, further filtered residual oil, and in the next cycle.

In two, fuel injection amount control:

Air compressor the injected oil in addition to play the role of lubrication, is mainly used to take air compressed in the heat generated by the fuel injection quantity, general air compressor factory have already set, non-professionals should not arbitrarily change.

In three, the lubricating oil flow function of main parts:

1 temperature control valve:

Temperature control valve main function is through control spray head lubricating oil humidity control air compressor exhaust temperature, in order to avoid the air moisture in the oil and gas in the barrel and the condensation of emulsified oil. When just starting up, reduces the temperature of lubricating oil temperature control valve is closed, the cold oil, without passing through the cooler and is sprayed directly into the machine body. When the temperature rises above 70 ℃, temperature control valve is , gradually opened to the oil cooler of the pathway, at 76 ℃fully open, the oil will all through the oil cooler and then sprayed into the machine body.

There are a few air compressor models without temperature control valve, but through the control of fan motor stops rotating to control temperature. When the exhaust temperature up to 85, fan running; when the exhaust temperature is below 75 ℃, fan stop automatically, so that the temperature is kept within a certain range.

2 oil cooler:

Oil cooler and aftercooler integrated.

3 oil filter:

Oil filter is a filter paper, filter precision in 10μ~ 15μbetween. Its function is to remove the impurities in the oil. Such as metal particles, dust, oil deterioration etc, and the normal operation of the protection bearing rotor. If the oil filter for blocking, it may lead to insufficient fuel injection amount influence host the service life of the bearing, machine head and exhaust temperature rises.

4 oil separators:

Oil separator filter using multilayer thin fine special fibers, compressed air contained in the lubricating oil mist after oil fine separator can be completely filtered, oil particle size can be controlled at less than 0.1 μ m, oil content can be less than 3PPM.

5 oil return check valve:

Oil separators for filtering oil remaining in the focus on the central round groove of the cartridge, the oil return pipe to avoid host, have been isolated from the oil and then with air discharge. In order to prevent the host compression chamber oil reflux, in the return pipe after setting a one-way valve, if the machine is in operation fuel consumption increase suddenly, should check the one-way valve throttle orifice is blocked.

In four, and the mechanical and electrical equipment limited company sincere intention to recommend the air compressor water heater, air compressor waste heat recovery equipment, as long as you plant air compressor, can 0 operation cost system of water. Scope of supply: China (excluding Hong Kong and Macao ).
