Summary
If the following items are normal, start and run for more than 30 minutes, start the fan and dry the fan at the operating temperature of the fan. Notes after the Roots blower water:
If the following items are normal, start and run for more than 30 minutes, start the fan and dry the fan at the operating temperature of the fan.
Notes after the Roots blower water:
1. Check whether the belt is affected with damp, if it becomes loose, adjust it tightly;
2. If the water quality is good and there is no suspended substance in it, the water can be directly drained;
3. Check whether the motor is damp.
4. Replace the lubricating oil, transparent gear lubricating oil;
5. If there are suspended solids in the water, please pay attention to clean up, do not adhere to the impeller and other accessories;
If the roots blower needs to be treated immediately after entering the water, if it is not handled properly, it will cause damage to the roots blower and motor. Please check the above items and make sure that they are correct before normal operation.
Function: The working principle of Roots blower is basically the same as that of turbo compressor. The gas flow rate is low and the pressure change is small. Generally, the specific volume change of the gas is not considered, that is, the gas is regarded as an incompressible fluid. Roots blowers are available in both right-hand and left-hand versions. Front view on the side of the motor: the impeller rotates clockwise, called the right rotating fan; the impeller rotates counterclockwise, called the left rotating fan.
Working principle: Roots blower is based on the principle of converting kinetic energy into potential energy. Rotating the impeller at high speed accelerates the gas, then decelerates and changes the flow direction, thereby converting kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas becomes radial as it flows through the impeller, and then enters the diffuser. In a diffuser, the gas will change the direction of flow, and the cross-sectional area of the pipe will increase to slow down the flow. The deceleration converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, followed by the expansion process. In a multi-stage roots blower, backflow is used to bring the airflow to the next impeller, thereby generating a higher pressure.
