What is the working principle of air compressor?How does an air compressor work?Guangdong hand takes you through the principles of air compressors.
Working principle of air compressor: drive the engine to start, through the triangle tape, drive the compressor crankshaft rotation, through the crank rod mechanism into the piston in the cylinder for reciprocating motion.When the piston moves from the cover to the side axis, the cylinder volume increases and the pressure inside the cylinder is lower than the atmospheric pressure.After reaching the lower dead center, the piston moves from the shaft to the cover side, the suction valve closes, the cylinder volume gradually decreases, the air in the cylinder is compressed, and the pressure rises. When the pressure reaches a certain value, the exhaust valve is pushed open, and the compressed air channel enters the gas storage tank, so that the compressor works repeatedly.
The compressed air is continuously transmitted to the air storage tank, gradually increasing the pressure in the tank, so as to obtain the required compressed air.
Detailed process of working principle of air compressor.
Inhalation process:
Screw type air inlet side of the suction mouth, must be designed to make the compression chamber can inhale fully, no air intake and exhaust valve group and screw compressor, air intake by a regulating valve opening and closing adjustment, as the rotor turns, main rotor tooth groove space when transferred to the inlet end wall openings, its space is the largest, the rotor tooth groove space and the freedom of the inlet air are interlinked, was all for tooth groove in exhaust air discharge, vent finished, tooth groove is in a vacuum state, when transferred to air inlet, outside air is inhaled, along the axial flow into the main rotor tooth groove.When air fills the entire tooth groove, the end face of the inlet side of the rotor turns away from the air inlet of the housing, and the air between the tooth groove is closed. The above is: [air intake process].
Sealing and conveying process: at the end of the suction of the main and deputy rotors, the teeth of the main and deputy rotors will be sealed with the enclosure. At this time, the air will be closed in the tooth groove and will not flow out, namely [sealing process].The two rotors continue to rotate, and the tooth peak and tooth groove coincide at the suction end, and the anastomotic surface gradually moves to the exhaust end, which is the [transport process].
Compression and oil injection process: in the transmission process, the meshing surface gradually moves to the exhaust end, that is, the tooth groove between the meshing surface and the exhaust port gradually decreases, the gas in the tooth groove is gradually compressed, the pressure increases, which is the [compression process].At the same time, the oil is sprayed into the compression chamber and mixed with air due to the pressure difference.
Exhaust process:
When the meshing surfaces of the rotor to the mines with casing exhaust, (highest compressed gas pressure at this time) began to discharge the compressed gases, until the teeth with tooth groove of the mating surface to the exhaust end face, the two rotor tooth meshing surface and chassis vent groove space is zero, namely complete (exhaust process), at the same time the rotor mesh surface and casing length of tooth groove between the inlet and the longest, the suction process is in progress.
3. Compression and oil injection process:
In the transmission process, the meshing surface gradually moves towards the exhaust end, that is, the tooth groove between the meshing surface and the exhaust port gradually decreases, and the gas in the tooth groove is gradually compressed and the pressure increases, which is the compression process.At the same time, the oil is sprayed into the compression chamber and mixed with chamber gas due to the pressure difference.
4. Exhaust process:
When the meshing surfaces of the rotor to the mines with casing exhaust, (the highest pressure of the compressed gas) of the compressed air to escape to until of teeth and tooth groove of the mating surface to the exhaust end face, the two rotor mating surface and the tooth groove casing vent space is zero, namely complete (exhaust process), at the same time the rotor mesh surface and casing length of tooth groove between the inlet and the longest, the suction process is in progress.
Above is the detailed air compressor working principle, want to in-depth understanding of other aspects of air compressor, pay attention to hand air compressor.
