Classification of air compressor

The general-purpose air compressor is in accordance with national standards, and the discharge pressure is 0.7 MPa. If it is higher or lower than this pressure, it is a non-standard special air compressor. The main types of air compressors are the following: According to the volume of gas (refers to the volume of the discharged gas per minute when the air compressor is converted into the inhaled state), there are small machines (discharge volume below 10 m3/min), Medium-sized aircraft (with displacement of 10 to 100 m3/min) and main engines (with displacement of 100 m3/min or more).


According to the structural type, there are rotary, piston, and diaphragm air compressors. Commonly there are piston type and rotary type screw type, slide type. Screw compressor rotors have complex rotor profiles and high manufacturing costs, but they are small, lightweight, and small parts. In the case of the same displacement, screw compressors are much more expensive than piston compressors, and maintenance personnel must also have specialized knowledge and experience.


According to the cylinder center line and relative position can be divided into vertical, horizontal, angle type air compressor. Among them, the angle type is divided into V type, W type, L type and so on. In general, because the piston compressor is a reciprocating machine, there is a certain degree of vibration. The angle type can well balance its inertial force. Therefore, most of the small and medium-sized piston compressors are angled. Only the compressors for vehicles and boats are established due to the limited floor space. The horizontal compressor is an initial product and is almost never produced now due to its lack of superiority.


According to the cooler mode, it can be divided into water-cooled and air-cooled air compressors. The water-cooled type uses tap water open circulation cooling; the air-cooled type is fan cooling.


According to the different engine can be divided into motor drive and diesel drive air compressor. Large electric type equipped with distribution cabinets, diesel-driven start by the battery, both compressors have direct connection, side connection (ie belt drive).


Lubrication can be divided into oil-free and oil-lubricated air compressors, and the latter is divided into splash-type and forced-type (ie, the oil pump and lubricator oil lubrication type).


According to the width of the basic configuration of the press can be divided into fixed (basic, no-basic) and mobile air compressor.
