Air compressor selection, their understanding of the principle of various kinds of air compressor
Author: 志和      Release Date:2014/4/19      View Count:2155
 

Since the air compressor from a fast necessary tool of modern industrial production,in just a few years time has played a small world of their own, a lot of enterprises /factories pursued. But people want to choose air compressor suitable according totheir different needs. How to choose suitable air compressor own, how do we choose to do, or that we have to distinguish how air compressor? We should select suitable for air compressor itself, first we must to understand the system of various air compressor (principle): the small make up for you to simply say the advantages of various air compressor working principle about the classification and their operationand their:

According to the principle of division of air compressor, air compressor can be divided into the volume of air compressor and speed compressor two, while the volume of air compressor can be divided into reciprocating air compressor and rotary compressor.Reciprocating air compressor is divided into piston with membrane; rotary into rotor,rotary screw and vane.

According to the above Xiaobian simple with complex, with a little wordy classifyingcomplex, you choose to suit their own factories / companies use air compressor? Butin fact, Xiaobian there are more important things not to share with you. In fact, one air compressor is suitable for their own use, working principle is one of the most important reasons, there are also very important is that they each piece of work principle Oh,below we together to learn about the working principle of each piece:

The working principle of volume type compressor:

Volume type compressor is through direct compressed gas, the gas volume reductionand to improve the gas pressure to. Volume type compressor according to thecharacteristics of cylinder measuring piston is divided into two types of rotary and reciprocating. The majority of oxygen with air compressors use volume.

The working principle of speed type air compressor:

Speed compressor is mainly depending on the gas in the high-speed rotating impeller,get a larger kinetic energy, then in the diffuser device rapid deceleration, the kinetic energy of gas into potential energy, thus increasing the air pressure. Velocity typemainly has two kinds of basic types of centrifugal and axial flow type.

The working principle of reciprocating air compressor:

The piston to do reciprocating motion, the cylinder is a cylinder. Reciprocatingincluding piston and membrane type two kinds, the piston is one type of the most widely used. So the oxygen in air compressor are the vast majority of the air compressor piston type.

The piston type air compressor with exhaust pressure, exhaust volume (volume),structure type and structure features for classification.

Connected with the exhaust volume is divided into:

1, the small air compressor 1m3 / min < exhaust volume 10m3 / min 

2, medium-sized air compressor 10m3 / min < exhaust volume 100m3 / min 

3, large air compressor exhaust, exhaust volume 100m3 / min air compressor suctionstate that free gas flow. General provisions: the shaft power, exhaust pressure < 15KW ≤ 1.4MPa for miniature air compressor.

According to the structure characteristics of divided into:

Single action: gas is only in the side of the piston compression.

2, double action: the gas is compressed on both sides of the piston.

3, water cooling type: refers to the cylinder with the cooling water jacket, water cooling.

4 cylinder, air-cooled: surface cast with fins, air cooling.

5, fixed type: air pressure unit fixed on the foundation.

6, mobile: air compressor on the mobile device to move.

7, lubricating oil: refers to the cylinder lubrication oil circulation lubrication, movement mechanism.

8, no lubrication oil: refers to the cylinder without lubrication, the piston and the cylinder is running dry, but the transmission mechanism is composed of oil circulation lubrication.

9, the oilless lubrication: cylinder drive mechanism were no oil lubrication.

In addition, divided into the crosshead (small oil free compressor), no<, SPAN space="0| " right-pos="63|9" left-pos="3293|9"> cross head (V,W low voltage micro air compressor); single stage compression, two stage or multi-stage compression,

According to exhaust pressure level is divided into:

Low pressure air exhaust pressure compressor ≤ 1.0MPa

Medium pressure air compressor discharge pressure < 10MPa 1.0MPa >

3, high pressure air compressor compressor discharge pressure < 100MPa 10MPa >

According to the central line of the cylinder and the relative position into the ground:

Vertical air compressor: the cylinder center line perpendicular to the ground layout.

Angle type air compressor: the cylinder center line forms an angle with the ground (V type, W type, L type).

3, the horizontal air compressor:: the cylinder center line parallel with the ground, the cylinder is arranged in one side of the crankshaft.

The dynamic balance type air compressor:: the cylinder center line parallel with the ground, the cylinder are symmetrically arranged on both sides of the crankshaft.

Reminder.

Chronicles and the electromechanical device limited company to recommend air compressor, water heater, air compressor heat recovery equipment, as long as youhave the air compressor factory, can 0 operation cost of producing hot water andheating.

See details > >

(this article mainly analyze the principle of work, various kinds of air compressor in the actual in the problem solving process is for reference only.)
