Advantages of centrifugal compressor

Centrifugal compressor is a kind of turbo compressor. It has the characteristics of large processing gas volume, small volume, simple structure, stable operation, convenient maintenance, and the gas is not polluted by oil, and it has the characteristics of more driving forms. reciprocating and rotary compressor

Advantage:

1. There are no wearing parts, and the maintenance cost is the lowest among compressors;

2. Compared with screw compressors, the leakage caused by the gap is less, so the single-stage efficiency is high;

3. Compared with the dry screw compressor, the number of parts and the number of processing man-hours are less, the processing accuracy is not high, and the production cost is low.

The two screws of the dry screw compressor face each other, so its characteristic is that a slight contact will form a surface contact, causing heat expansion, scorching and jamming. On the other hand, the biggest feature of a centrifugal compressor is the impeller blades. It is opposite to the volute by a line, so even if a few contacts are made, it is a line contact, and the blades pass through like a blade without scorching. Therefore, its biggest advantage is that there are far fewer accidents than dry screw compressors. reciprocating and rotary compressor

The characteristic of the centrifugal compressor is that by reducing the intake valve, the intake volume can be reduced without entering, and the point of action can be moved to reduce the intake pressure to reduce the increase in pressure ratio. reciprocating and rotary compressor

The working principle of centrifugal compressor

Generally speaking, the main goal of increasing gas pressure is to increase the number of gas molecules per unit volume, that is, to shorten the distance between gas molecules and molecules. In order to achieve this goal, the method of gas dynamics is used, that is, the use of mechanical operations. The work element (high-speed rotating impeller) does work on the gas, so that the pressure of the gas under the centrifugal action is increased, and the kinetic energy is also greatly increased. Then this part in the diffuser flow channel is transformed into static pressure energy, which makes the gas The pressure is further increased, which is the working principle of the centrifugal compressor. reciprocating and rotary compressor

The operation of the main engine of the centrifugal compressor is based on the normal operation of the auxiliary equipment. The auxiliary equipment includes the following aspects:

Lubricating oil system

cooling system

Condensate system

Control System

Dry gas sealing system
