Cause analysis of leakage of star discharger

If the star discharger leaks, it will not only cause certain losses to the material transportation, but also reflect the discharger itself has problems, so where the damage of the star discharger will cause the material leakage? Today, let's talk about Tianlan environmental protection equipment with you!


Cause analysis of leakage of star discharger 1


The problem of material leakage often occurs in the use of star type discharger, because the gap at the connection of discharger wall of impeller is too large, which is easy to cause material leakage during discharging. In this way, rubber pad can be fixed on the impeller to solve the problem of material leakage. The shell of discharger wall will be worn out when it is always discharging and friction, causing material leakage. Discharger is a very important part of all kinds of dust removal equipment, The machine has a series of advantages such as compact structure, beautiful appearance, convenient use, stable operation, low noise, etc. due to the bearing of the discharger, the gear box is a certain distance away from the shell, which is resistant to high temperature for ordinary dischargers in the past, Generally, the structure of the discharger is composed of a rotor impeller with several blades, a shell, a seal, a reducer and a motor. When the material in the upper bin falls by its own weight and fills the gap between the blades, it is discharged from the upper part with the rotation of the blades. This is the working principle of the discharger. The discharger can discharge continuously, Because of its simple operation, long service life of the equipment.


Star type discharger is commonly used in pneumatic output system. For pressure output system or negative pressure output system, star type discharger can evenly and continuously supply material to the conveying pipe, so as to ensure that the gas and solid in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally. At the same time, it can block the upper and lower air pressure of discharger and play the role of air locking. Therefore, star discharger is an important part in pneumatic conveying system.


As a kind of uniform feeding equipment for all kinds of powder, star unloader is used in all kinds of use environment. Facing the complex material characteristics and different use requirements, running and leakage is one of the serious problems in the current user response when completing the feeding.


In the process of discharging and feeding, the running and leakage of the star discharger are mainly concentrated in the rotating shafts at both ends of the shell, especially in the environment of fine powder with good fluidity and pneumatic conveying. As one of the professional star discharger manufacturers, Pratt & Whitney dust removal Co., Ltd. now shares the causes and treatment of the main running and leakage of star discharger based on years of on-site feedback information and production experience.




Analysis of the main reasons for the running and leakage of star discharger 2


The star discharger relies on the rotation of the impeller to realize uniform discharge. Since the impeller rotates in the shell, there must be enough gap between the impeller and the shell, otherwise the impeller can not rotate. If the gap between the impeller and the shell causes material leakage without rotation, and causes part of the material to enter the gap between the two ends of the impeller and the shell, and the main shaft rotates too fast During the process, the material is blown to the outside of the shell along the main shaft due to the wind pressure, resulting in the material running from both ends of the bearing.
