Decanter centrifuges are characterized by their continuous operation, the presence of a scroll (a helical screw that rotates at a slightly slower speed than the bowl and conveys the solids towards the outer wall of the bowl), and a solids discharge port located on the outer wall of the bowl. They are used in a wide range of industries and .
On Nov 14, 2013, an important discussion took place regarding the impact of closing the discharge valve in a centrifugal pump while it is running. This issue is critical not only for centrifugal pumps but also for positive displacement (PD) pumps. In this article, we will delve into the various problems that can arise when the discharge valve is closed during operation, as well as the consequences of closing the valve when starting the pump.
>If you start the pump discharge valve closed, it means no discharge head minimum resistance to the pump and minimum current drawn. Even though current taken during startup is more than
Centrifugal Discharge Valve Closed
Centrifugal pumps rely on the principle of centrifugal force to move fluids through the system. When the discharge valve is closed while the pump is running, several issues can occur. One of the primary problems is the buildup of pressure within the pump and the associated increase in power consumption. The pump may struggle to maintain its flow rate, leading to inefficiencies and potential damage to the pump components.
Pump Discharge Valve Closed
In general, closing the discharge valve of a pump restricts the flow of fluid, causing back pressure to build up within the system. For centrifugal pumps, this can result in cavitation, a phenomenon where vapor bubbles form due to low pressure regions in the pump. Cavitation can lead to erosion of the pump impeller and other components, reducing the pump's efficiency and lifespan.
Discharge Valve Closed When Starting Pump
Closing the discharge valve when starting a pump can also have detrimental effects. When the pump is started with the discharge valve closed, the pump may experience a sudden surge in pressure, causing stress on the pump components. This can lead to mechanical failures, including seal damage and bearing wear. Additionally, the motor driving the pump may draw excessive current, leading to overheating and potential burnout.
Please explain what are all the problems that pump will encounter if the discharge valve is closed in the running condition for both centrifugal and PD pumps. In case of …
Dewatering Decanter crudMaster. For clear clarification, liquid separation and solids dewatering in chemical and mineral processing applications. The heavy or light liquid phase is discharged under pressure by use of a centripetal pump while the other liquid phase is discharged by drain tubes. CIP-compatability of the decanter can be assured.
