Centrifugal Pump is Evacuated Phenomenon How to Do? Centrifugal pump in the practical application, there will always be a variety of conditions, one of the many reasons for centrifugal pump failure when the phenomenon of evacuation, always make you feel very headache. What if the centrifugal pump is evacuated? After the pump is pumped, or during the process of pumping1) The vibration of the pump body is large, and the dynamic and static rings of the mechanical seal will continue to intermittently collide, resulting in leakage, and the failure of the mechanical seal structure in serious cases;2) The compression of the dynamic and static ring of the mechanical seal is the sum of the medium pressure and the pretension force of the spring, when evacuated, the medium pressure will not be there, the contact pressure of the dynamic and static ring will become smaller, and the seal will fail;3) After […]
