Corporation of centrifugal pumps: In actual applications, the centrifugal pump always occurs in various conditions. One of the many reasons for the failure of the centrifugal pump when the phenomenon is short, it will always make everyone feel a headache. What if the centrifugal pump takes time? The editor summarizes the status, reasons and treatment measures of the centrifugal pump, and hopes to help your work.

After pumping empty, or during the process of drawing, 1) The pump body vibrates large, and the mechanical sealing and static ring will continue to intermittent collisions, resulting in leakage, and the mechanical sealing structure is invalid in severe cases;

2) The tightness of the dynamic static ring of the mechanical seal is the sum of the medium pressure and the pre -tightening force of the spring. When it takes time, the medium pressure will not, and the contact pressure of the dynamic static ring will become smaller, and the seal will be invalid;

3) After pumping, the mechanical sealing static ring surface of the self -buffer scheme (that is, the pumping medium is rinsed with) loses cooling and lubrication, dried rubble, mechanical sealing failure.
