Air compressors (or air compressors for short) areCore power source equipment for pneumatic systemsIts essential function is to transfer the primary motor (e.g., electric motor or diesel engine) of themechanical energyEfficient conversion togas pressure energyThis provides a continuous supply of compressed air that meets the requirements.

Core features

1. Energy conversion core: As the main body of the electromechanical pilot gas source device, the core function is to realize theMechanical energy to gas pressure energyThe conversion.

2. Pneumatic system heart: Provides compressed air, the necessary power source for the entire pneumatic system (including pneumatic tools, actuators, control valves, etc.).

3. Pressure generating device: It is a key device for generating and maintaining the air pressure required by the system.

Typical operating principle (piston type as an example)

The piston compressor realizes the above energy conversion and air supply through the following mechanism:

1. Power Input: The electric motor directly drives the compressor, which rotates the crankshaft.

2. Motion Transition: The rotary motion of the crankshaft is converted by the connecting rods into the piston's movement in the cylinder.reciprocating linear motionThe

3. Inhalation process: When the piston goes down, the cylinder volume increases and the internal pressure decreases. Under the action of pressure difference, the outside air passesair filter(filtering out impurities, often with integrated muffling) and the opening of theinlet valveis sucked into the cylinder.

4. Compression process: As the piston travels upward, the cylinder volume decreases and the air drawn in iscompressedThe pressure and temperature increase as a result.

5. Exhaust process: When the pressure in the cylinder rises sufficiently to overcome the exhaust valve spring force and pipe resistance, theventing valveOpen. The compressed air passes through theexhaust linerespond in singingCheck valves (non-return valves) bouncegas canisterThe

6. Energy storage and voltage stabilization: The tank stores compressed air and serves asbuffer,Stabilizes system pressure,Separation of condensaterole and to meet instantaneous high flow demands.

7. Automatic control (start-stop)

   • When the pressure in the storage tank reaches the presetRated exhaust pressure(e.g., 0.7 MPa).Pressure RelayAction to control the air compressorautomatic shutdownThe

   • When the tank pressure drops due to gas usage to the presetstarting pressure(e.g., 0.5 - 0.6 MPa), the pressure relay operates again to control the compressor.automatic activationThe control system starts a new round of compression and inflation process. This control method realizes on-demand gas supply and energy-saving operation.
