The formation and harm of carbon deposits in air compressor
How does air compressor coke formation form?
The reasons for the formation of carbon deposits in air compressors are more complicated. In terms of air compressor oil lubrication, the main reason is that the oil used in the internal lubrication system of the air compressor is often in the form of mist and high temperature, high pressure, high oxygen partial pressure air and metal The contact of the catalyst causes the air compressor oil to rapidly oxidize and deteriorate. On the other hand, the continuous evaporation of the air compressor oil makes the oil of the heavier components remain in the exhaust valve cavity and exhaust pipe on the top of the piston, which is continuously heated and decomposed, dehydrogenated and polymerized. The product is mixed with the mechanical impurities in the inhaled gas and the metal wear debris in the compressor, and is deposited on the surface of the body to be further heated, which becomes carbon deposits.
What is the hazard of carbon deposits in air compressors?
When the air compressor generates more carbon deposits at the exhaust valve and exhaust pipe, the exhaust valve will not move flexibly and close tightly, causing the exhaust gas to flow back into the cylinder and repeatedly compress (ie, secondary compression), so that the gas The temperature rose rapidly. The high gas temperature intensifies the oxidation reaction of the lubricating oil, and the reaction heat cannot be released in time, causing the gas temperature in the exhaust pipe to continue to rise. When the temperature reaches the spontaneous ignition point of the lubricating oil, the air compressor oil accumulated in the carbon deposits starts to burn. Incomplete combustion products, thermal decomposition products of the oil, oil mist in the gas and air form an explosive gas.

1) Leakage. There is no contact between the rotors and between the rotor and the housing during operation, and a certain gap is maintained, so gas leakage will occur. When the pressure increased gas leaks to the suction pipe and the sucking groove through the gap, the exhaust volume will be reduced.

The scroll compressor is a positive displacement compressor, and multiple compression chambers are formed by the meshing of the scroll rotor and the scroll stator. With the translation and rotation of the vortex rotator, the volume of each compression chamber continuously changes to achieve gas inhalation and compression.

German FAG bearings (especially rolling bearings) are divided into two kinds of structure with cage and without cage. Among them, large-scale FAG bearings are generally required to withstand larger loads, often without a cage, but filled with rolling elements between the inner and outer raceways. And most of the small and medium rolling bearings are with cages.

1. Regular maintenance and maintenance of main components In order to enable the air compressor to operate normally and reliably and ensure the service life of the unit, a detailed maintenance plan must be formulated, manned operations, regular maintenance, and regular inspection and maintenance are required to keep the air compressor unit clean, oil-free, and dirt-free.

1 Why is the most harmful of oil in the air? Answer: In some places with strict requirements, such as pneumatic control systems, a drop of oil can change the condition of the air holes. Paralyze the production line that was originally running normally and automatically.
