The air compressor is configured with electromechanical equipment sleeves, only a single power connection and compressed air connection, and a built -in cooling system.Do you know what kinds of air compressors are?If the working principle is divided, which type can be divided into two types?How is the air compressor selected?Presumably many people are still unclear.Next, you can learn more about the air compressor.
The main purpose of the air compressor
A. Traditional air dynamic: air dynamic tools, rock drilling machines, wind picks, pneumatic wrenches, pneumatic sandblasts
B. Instrument control and automated devices, such as the tool replacement of the processing center.
C. Vehicle brake, doors and windows are opened and closed
D. Use compressed air to send latitudes with compressed air in the jet machine to replace the shuttle
E. Food and pharmaceutical industry, use compressed air stirring slurry
F. The start of the large -scale shipping diesel engine
G, wind tunnel experiments, underground channel ventilation, metal smelting
H, oil well fracture
i, high -pressure air blasting coal mining
J, weapon system, missile launch, torpedo launch
K, submarine floating, salvage of shipwreck, underwater oil exploration, air cushion boat
l, tire inflation
m, spray paint
n, bottle blower
O.
P. Industrial control power (drive cylinder, pneumatic element)
Q. Production of high -pressure air for cooling and drying of processing parts
Classification of air compressor
The air compressor can be divided into two categories: speed and volume.
The air machine is divided into: 1. speed type; 2. volume type; volume type is divided into rotary and pushy type; rotation: (1) rotor type; (2) screw type; (3) slide sheet.Packing: (1) Pistons; (2) Membrane.
Speed ??type: It is based on the role of gas to rotate the impeller at a high speed, which obtains greater kinetic energy. Then, the speed of the gas is reduced sharply in the transposition device, which transforms the kinetic energy of the gas into potential energy, thereby improving gas pressure.The speed type mainly includes two basic types of centrifugal and axial flow.
Volume type: It is divided into two types: rotary and reciprocating by directly compressing the gas volume to reduce the gas pressure to improve gas pressure.Most of the air compressors prepared by oxygen compartment are used.
Rotating type: Pistons are rotating movements. Pistons are also called rotary, rotor quantity varies, and the cylinder shapes are different.The rotation type includes rotor, screw, and slide, including piston air compressors.
Pour back: The piston is performed, and the cylinder is a cylinder shape.The reciprocating type includes two types: Pistons and membrane types. Among them, the piston type is currently the most widely used type.The vast majority of the oxygen compressors use a piston.
How to buy air compressor
1. Decision of stress:
1. The higher the pressure, the greater the power consumption.The pressure caused by the size and length of the pipeline must be considered, and the use of pressure is both the lower limit pressure.
2. List the use of various types of use of various types of use. If the pressure is too different, it is necessary to purchase an air pressure machine with different pressures or using a supercharger. It cannot reduce the use of pressure and increase electricity expenditure.
Second, the choice of the model:
1. It is advisable to calculate the total actual use of air volume plus the amount of margin.
2. The actual exhaust volume listed in the companys recording is proved according to the US ASME air measurement equipment.
3. Pay attention to the energy consumption value to save electricity.
Third, venue:
1. Must be wide and lighten up to facilitate operation and maintenance.
2. Low temperature, low dust, clean air, and good ventilation, room temperature should be less than 40 ° C.
Fourth, cooling water and water quality
1. The temperature of the cold water should be low, and the cooling water tower should be cooled.
2. Pay attention to the pH value of cooling, which should be maintained at about 7 to prevent scaling and increase the cost of cleaning.
3. Pay attention to the cooling effect of the cooler. Generally speaking, the compressed air export temperature should be about 40 ° C.
Fifth, compressing air quality and requirements:
The compressed air contains a lot of water with 100%relative humidity. It causes great damage to precision instruments, pneumatic tools, pneumatic equipment, valves, instruments, pipelines, etc., because the water will cause rust, blockage instruments, reduce the quality of the finished product, and reduce the quality of the finished product.Damage equipment and losses a lot of money are repaired and maintained, so it is necessary to install the compressed air net system.
