The core component of the air compressor is the compressor mainframe, is a volumetric compressor, air compression is achieved by the device in the casing of the mutual parallel meshing of the tooth groove of the yin and Yang rotor volume changes. The rotation of the rotor in the casing with its precise fit makes the gas between the rotor teeth groove continuously produce periodic volume changes along the rotor axis, from the inlet side to the discharge side, to complete the inlet, compression, exhaust three work processes. Therefore, the twin-screw rotor profile technology determines the grade of screw air compressor product positioning.
The workflow of air compressor.
Air through the inlet filter will be filtered out of the dust or impurities in the atmosphere, by the inlet control valve into the compressor host, in the compression process and sprayed into the cooling lubricant mixture, by the compression of the mixed gas from the compression chamber into the oil and gas separation tank, at this time, the compression of the discharge of oil-containing gas through the collision, interception, gravity, the vast majority of the oil medium is separated down, and then into the oil and gas separator for secondary separation When the air is compressed to the specified pressure value, the minimum pressure valve opens and the compressed air is discharged to the cooler for cooling and finally sent to the use system.
The compressor is driven directly by an electric motor, which produces a rotary motion of the crankshaft and drives the connecting rod to produce reciprocating motion of the piston, causing the cylinder volume to change. Due to the change of pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the inlet valve. In the compression stroke, due to the reduction of the cylinder volume, the compressed air enters the storage tank through the exhaust pipe and the check valve (check valve) through the exhaust valve, when the exhaust pressure reaches the rated pressure of 0.7MPa, it is automatically stopped by the pressure switch control. When the tank pressure drops to 0.5 - 0.6MPa, the pressure switch is automatically connected to start.
Air compressor installation site selection.
1. Air compressor installation, must be wide and well-lit place, in order to facilitate the operation and maintenance.
2. The relative humidity of the air should be low, less dust, clean and well-ventilated air, away from flammable and explosive, corrosive chemicals and harmful and unsafe items, and avoid close to places that emit dust.3. When the air compressor is installed, the ambient temperature in the installation site should be higher than 5 degrees in winter and lower than 40 degrees in summer, because the higher the ambient temperature, the higher the air compressor discharge temperature, which will affect the performance of the compressor, if necessary, the installation site should be set up ventilation or cooling devices.
4. If the factory environment is poor, dusty, must be installed with pre-filtering equipment.
5 Air compressor installation site air compressor units should be arranged in a single row.
6 reserved access, with the conditions can be installed overhead crane, in order to facilitate the maintenance of air compressor equipment.
7 reserved maintenance space, air compressor and the wall must have at least 70 centimeters between the distance.
8. Air compressor from the top space distance of at least one meter or more.
