What are the causes of vibration during the operation of chemical pumps?

　　Chemical pumps in the process of operation, vibration often occurs, which will reduce the service life of the pump and make the operation of the safety is affected, therefore, understand the causes of vibration for the correct solution to the problem is of great significance. How to solve the technical problems caused by vibration in the pump? First of all, we need to understand the causes of vibration, the next Schaederbauer pumps and valves through the following points to explain the causes of vibration:

　　First, the pump bearing and shaft tile damage

　　Due to damage to the shaft tile and bearings, may lead to axial vibration of the pump shaft, resulting in vibration in the pump, so you need to regularly check the pump bearings and shaft tile damage, timely replacement of damaged parts.

　　Second, the pump before the vortex

　　Due to the influence of the pump before the vortex, will produce vortex vibration in the process of fluid into the pump impeller, which will lead to the internal vibration of the pump, so it should be used to eliminate the vortex of safe and reliable methods to reduce the impact of vortex vibration.

　　Third, abnormal operation

　　Due to the lack of reliability and stability of the pump, there may be a stall phenomenon in the pump operation, that is, the speed than the normal preset value has a significant change, which will increase the internal fluid vortex convergence, which will make the pump internal vibration, so it should be strengthened to pump reliability, so that the pump operation is more stable.

　　Fourth, drive precision is not enough

　　Due to the drive accuracy is not enough, especially the AC drive, there will be periodic jitter, which will cause the pump internal fluid to repeatedly push, thus generating vibration, so to use the higher accuracy, good reliability of the drive, in order to reduce vibration.

　　Fifth, the pump impeller structure is unreasonable

　　Due to the unreasonable structure of the pump impeller, in the process of pump operation, the pump impeller internal fluid will appear uneven flow, thus generating vortex vibration, and ultimately cause vibration inside the pump, so it should be reasonable to design the structure of the pump impeller, in order to reduce the impact of the vortex vibration.

　　Six, external vibration

　　Due to the impact of external vibration, the pump and its ancillary equipment will let the pump vibration, which will lead to internal vibration of the pump, so measures should be taken to mitigate the impact of external vibration in order to reduce the occurrence of internal vibration.

　　In general, the chemical pump vibration in the operation process has many reasons, the above list is only a few of them, there are many other reasons, such as the pump wheel vane, improper installation, etc., may lead to internal pump vibration. Therefore, only through continuous exploration and analysis, in order to take into account various factors, accurately find out the cause of vibration, in order to correctly solve the problem to provide the necessary basis.
