How to classify the high pressure in air compressor type air compressor

　　Air compressor can be divided into two kinds of speed type and volume type according to the working principle.

　　The air machine is divided into 1 parts: speed and speed; 2, volume type; volume type is divided into rotary and reciprocating; rotary type: (1) rotor type; (2) screw type; (3) slide type. Reciprocating: (1) piston type; (2) membrane type.

　　Speed mode: the larger kinetic energy can be obtained by the action of gas on the impeller with high speed, and then the speed will decrease rapidly in the diffuser, so that the kinetic energy of the gas can be changed into potential energy, thus improving the gas pressure. The speed type mainly consists of two basic types of centrifugal and axial flow.

　　Volumetric type: by directly compressing the gas, the volume of the gas is reduced to achieve the purpose of increasing the gas pressure. According to the characteristics of the cylinder piston, the volume type is divided into two categories: the rotary type and the reciprocating type. Most of the air compressor chamber prepared by displacement.

　　The rotary piston rotates, the piston is also known as the stem, the number of rotor ranging from a cylinder shape. The revolving type includes the piston type air compressor, such as the rotor, the screw type, the slide type, and so on.

　　Reciprocating: the piston does the reciprocating movement, and the cylinder is cylindrical. Reciprocating consists of two types of piston and membrane, of which the piston is the most widely used type at present. Most of the oxygen compressor piston. The classification, model representation method, structure characteristics and working principle of the piston type air compressor are introduced as follows:

　　The piston type air compressor is generally classified by exhaust pressure, exhaust volume (volume flow), structure type and structure characteristics.

　　1. according to the height of the exhaust pressure, it is divided into:

　　Low pressure air compressor exhaust pressure is less than 1.0MPa

　　Medium pressure air compressor exhaust pressure is less than 10MPa 1.0MPa. "

　　High pressure air compressor compressor exhaust pressure is less than 100MPa 10MPa. "

　　2. the size of the discharge volume is divided into:

　　1m3 / min < small air compressor exhaust is equal to or less than 10m3 / min

　　10m3 / min < medium air compressor exhaust is equal to or less than 100m3 / min

　　Large air compressor exhaust volume > 100m3 / min

　　The exhaust volume of the air compressor refers to the free flow of gas in the inhalation state.

　　General requirements: axle power is less than 15KW, the exhaust pressure is less than 1.4MPa for micro air compressor.

　　3. according to the relative position of the center line of the cylinder and the ground, it is divided into:

　　The vertical air compressor - the center line of the cylinder is arranged vertically to the ground.

　　Angle air compressor - the center line of the cylinder and the ground to a certain angle (V, W, L, etc.).

　　The horizontal air compressor, the central line of the cylinder is parallel to the ground, and the cylinder is arranged on the side of the crankshaft.

　　The dynamic balance air compressor, the central line of the cylinder parallel to the ground, is arranged symmetrically on both sides of the crankshaft.

　　4 according to the structural characteristics, they are divided into:

　　Single action - the gas is compressed only on the side of the piston.

　　Double action - the gas is compressed on both sides of the piston.

　　Water cooling - the cylinder with cooling water jacket and water cooling.

　　Air cooling type - the surface of the cylinder is cast with a heat sink, and the air is cooled.

　　The fixed - air compressor set is fixed on the foundation.

　　The mobile - air compressor unit is placed on the mobile device to move easily.

　　Oil lubrication - Lubrication of oil in cylinder, circulation lubrication of lubricating oil in movement mechanism.

　　Oil free lubrication - the non oil injection lubrication in the cylinder, the piston and the cylinder for dry operation, but the transmission mechanism is lubricated by lubricating oil.

　　All oil free lubrication - no oil lubrication in cylinder drive mechanism.

　　In addition, it is divided into cross head (medium and small oil free air compressor), no cross head (V, W type low pressure micro air compressor); single stage compression, two stage or multistage compression,

　　Dew point temperature:. Keep the moisture content in the air constant, and make it lower the temperature, when the water vapor is saturated with the temperature of saturation, that is, dew point temperature. The dew point temperature can also be used to indicate the amount of water gas. The higher the dew point temperature, the more water and gas in the air.
