How to improve the pressure of centrifugal impeller
Personal opinion: I don't know why you're trying to improve the pressure. I'd like to remind you. Centrifugal impeller is generally used to pressurize the gas, the impeller speed is usually very high, basically tens of thousands of revolutions / minutes, you must increase speed when you must be careful Oh. The impeller itself has a certain imbalance in quality, this imbalance in the quality of centrifugal force under the action of the shaft has a shear force, the higher the speed, the greater the shear force, to a certain extent, will bend or break the axis. Such a high speed, once an accident, can be great event.
The pressure you mean is the output pressure.The centrifugal impeller speeds up the fluid by rotating centrifugal force. The greater the centrifugal force, the greater the velocity of the fluid. The acceleration process is the compression process. You have to pressure, very simple, directly increase the speed of centrifugal impeller, you can play the role of pressure. If the speed does not add up, there is another way, that is, in the case of a certain speed, increasing the diameter of the centrifugal impeller (ie replace the larger diameter centrifugal impeller) can also play a role in pressure. Principle: the centrifugal force is proportional to the speed and diameter of the rotation.
If you encounter compression equipment low pressure to increase pressure, not sloppy treat, first determine the cause of low pressure, is not part of the rotor beating is too large, causing wear of impeller, the pressure is insufficient.
