Introduction of Magnetic Suspension Centrifugal Blower For sale: Knowledge about the loading process of centrifugal blowers!

Author:


The centrifugal blower is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. So do you know the loading process of the centrifugal blower? Let's follow the editor of Magnetic Suspension Centrifugal Blower For sale to have a simple understanding!

Introduction of Magnetic Suspension Centrifugal Blower For sale: Knowledge about the loading process of centrifugal blowers!


The loading process of the compressor is a process from the unloaded (no-load) state to the constant pressure control to reach the pressure setting value and supply air to the system. When the control system receives the load command, the control system compares the actual pressure of the system with the set pressure. When the set pressure of the system is greater than the actual pressure, the intake guide vane will gradually open from 10% when the load is empty, and the motor The current rises; when the current exceeds 230A (the TL set value), the vent valve is closed, and the intake guide vane and the vent valve are adjusted together to keep the current of the motor at 230A until the third-stage pressure rises and the system pressure reaches Set the value and enter the constant pressure control state. The speed of this loading process and whether it can be successfully loaded are related to the proportionality of the control parameters and the integration time. When the system demand is large, the integral time should be increased to reach the speed of the pressure setting value; on the contrary, when the system demand is small, it should be adjusted smaller, otherwise it is too sensitive, which will cause the valve to oscillate and fail to load.
In summary, the editor of Magnetic Suspension Centrifugal Blower For sale tells: Introduction to relevant knowledge about the loading process of centrifugal blowers.
