Why don't self-priming pump absorb water? How to solve this problem?

Self-priming pump belongs to the self-priming centrifugal pump, it has many advantages, such as high efficiency, stable operation, long service life and so on. It was also because of the existence of these advantages, so established its status in the field of machinery manufacturing. Self-priming pump can be applied in many fields, created many multidimensional convenient for our life. Of course, in the process of using the self-priming pump, we will inevitably encounter some tricky problems. This time, if you can solve the solution of their own, not only have to spend money to repair company also. And small make up to introduce to you today, is about the content, why don't self-priming pump water? Have you met this aspect of the failure?

If joint leakage, it can also cause the same problem. Of course, the solution is the same, fixed joint. shaft and the pump set between clearance under normal circumstances, the pump shaft and is should not be a gap between pump sets, unless the machining accuracy. shaft and the pump set, if the clearance between the self-priming pump in the operation of the process, can produce leakage phenomenon. Air leakage phenomenon directly told to everybody: self-priming pump is impossible to sheung shui. Can actually let self-priming pump suction is not the cause of the water has a lot of, in addition to the above to introduce these points, the impeller damage or loose, untight seal bearing body, pump body, such as water shortage, can also cause the emergence of the phenomenon.
